Deaf signers and hearing non-signers have previously been shown to recruit partially different brain regions during simple arithmetic. In light of the triple code model, the differences were interpreted as relating to stronger recruitment of the verbal system of numerical processing, that is, left angular and inferior frontal gyrus, in hearing non-signers, and of the quantity system of numerical processing, that is, right horizontal intraparietal sulcus, for deaf signers. The main aim of the present study was to better understand similarities and differences in the neural correlates supporting arithmetic in deaf compared to hearing individuals. Twenty-nine adult deaf signers and 29 hearing non-signers were enrolled in an functional magnetic resonance imaging study of simple and difficult subtraction and multiplication. Brain imaging data were analyzed using whole-brain analysis, region of interest analysis, and functional connectivity analysis. Although the groups were matched on age, gender, and nonverbal intelligence, the deaf group performed generally poorer than the hearing group in arithmetic. Nevertheless, we found generally similar networks to be involved for both groups, the only exception being the involvement of the left inferior frontal gyrus. This region was activated significantly stronger for the hearing compared to the deaf group but showed stronger functional connectivity with the left superior temporal gyrus in the deaf, compared to the hearing, group. These results lend no support to increased recruitment of the quantity system in deaf signers. Perhaps the reason for performance differences is to be found in other brain regions not included in the original triple code model.

Self-driving buses will be part of the public transportation system of the future, and they must therefore be accessible to all. The study reported in this paper examines the user experiences of 16 children with mild intellectual disability riding a self-driving bus. The qualitative analysis, performed by iterative affinity diagramming, of interviews, observations, and a co-design session with five of the children, suggests that familiar situations were characterized by contemplation and curiosity, while unfamiliar ones were characterized by surprise or confusion. The temporal structure of past, present, and future situations in the field of attention played a significant role in the children’s experiences. This leads to design considerations for an explainable interior of self-driving buses.

We aimed to identify effect sizes of age discrimination in recruitment based on evidence from correspondence studies and scenario experiments conducted between 2010 and 2019. To differentiate our results, we separated outcomes (i.e., call-back rates and hiring/invitation to interview likelihood) by age groups (40-49, 50-59, 60-65, 66+) and assessed age discrimination by comparing older applicants to a control group (29-35 year-olds). We conducted searches in PsycInfo, Web of Science, ERIC, BASE, and Google Scholar, along with backward reference searching. Study bias was assessed with a tool developed for this review, and publication bias by calculating R-index, p-curve, and funnel plots. We calculated odds ratios for callback rates, pooled the results using a random-effects meta-analysis and calculated 95% confidence intervals. We included 13 studies from 11 articles in our review, and conducted meta-analyses on the eight studies that we were able to extract data from. The majority of studies were correspondence studies (k=10) and came largely from European countries (k=9), with the rest being from the U.S. (k=3) and Australia (k=1). Seven studies had a between-participants design, and the remaining six studies had a within-participants design. We conducted six random-effects meta-analyses, one for each age category and type of study design and found an average effect of age discrimination against all age groups in both study designs, with varying effect sizes (ranging from OR = 0.38, CI [0.25, 0.59] to OR = 0.89, CI [0.81, 0.97]). There was moderate to high risk of bias on certain factors, e.g., age randomization, problems with application heterogeneity. Generally, there’s an effect of age discrimination and it tends to increase with age. This has important implications regarding the future of the world’s workforce, given the increase in the older workforce and later retirement.

The increasing adoption of open science practices in disability research and education highlights the need for tools that facilitate FAIR (findable, accessible, interoperable, reusable) data sharing. Community-augmented meta-analysis (CAMA) platforms have emerged as promising solutions, enabling dynamic, interactive meta-analyses while ensuring reproducibility (Tsuji et al., 2014). However, evidence synthesis quality remains a challenge in educational research (Nordström et al., 2022).

We present the development of a CAMA platform for Evidence in Learning, Didactics, and Disability research, focusing on quantitative methods for conducting frequentist and Bayesian meta-analyses of educational interventions built with R and Shiny. The platform organizes studies into categories for typically developing students and students with intellectual disabilities, subdivided by educational domains: writing, reading, math, science, and others.

Our objectives are to develop a platform that enables sharing of high-quality meta-analyses, incorporating features such as publication bias assessment, effect size aggregation, and moderator analysis, with mandatory risk of bias assessments for dataset inclusion, and to design a versatile platform suitable as both a pedagogical and research tool. The platform will serve as a guide on evidence-based practices for practitioners and an easy-to-use tool for students and researchers aiming to conduct meta-analyses. During the poster session visitors will get a hands-on experience of the platform. 

Background Numerous resting-state studies on attention deficit hyperactivity disorder (ADHD) have reported aberrant functional connectivity (FC) between the default-mode network (DMN) and the ventral attention/salience network (VA/SN). This finding has commonly been interpreted as an index of poorer DMN regulation associated with symptoms of mind wandering in ADHD literature. However, a competing perspective suggests that dysfunctional organization of the DMN and VA/SN may additionally index increased sensitivity to the external environment. The goal of the current study was to test this latter perspective in relation to auditory distraction by investigating whether ADHD-adults exhibit aberrant FC between DMN, VA/SN, and auditory networks. Methods Twelve minutes of resting-state fMRI data was collected from two adult groups: ADHD (n = 17) and controls (n = 17); from which the FC between predefined regions comprising the DMN, VA/SN, and auditory networks were analyzed. Results A weaker anticorrelation between the VA/SN and DMN was observed in ADHD. DMN and VA/SN hubs also exhibited aberrant FC with the auditory network in ADHD. Additionally, participants who displayed a stronger anticorrelation between the VA/SN and auditory network at rest, also performed better on a cognitively demanding behavioral task that involved ignoring a distracting auditory stimulus. Conclusion Results are consistent with the hypothesis that auditory distraction in ADHD is linked to aberrant interactions between DMN, VA/SN, and auditory systems. Our findings support models that implicate dysfunctional organization of the DMN and VA/SN in the disorder and encourage more research into sensory interactions with these major networks.

Purpose For cochlear implant users, the ability to use the telephone is often seen as an important landmark during rehabilitation and an indicator of cochlear implant benefit. The goal of this study was to develop a short questionnaire exploring the ability to use the telephone in cochlear implant users, named Telislife, and test it in a group of experienced users.

Method This prospective multicenter study was based on the completion of self-administrated questionnaires. The Telislife includes 20 items using a 5-point Likert scale for answers. Speech recognition scores were obtained with monosyllabic word lists at 70 dB HL. Quality of life was evaluated with the Nijmegen Cochlear Implant Questionnaire. This study included 55 adult patients wearing a cochlear implant for over 1 year.

Results The Telislife questionnaire showed excellent reliability (Cronbach's α = .91). A significant correlation was found between Telislife scores and Nijmegen Cochlear Implant Questionnaire scores (r = .69, p < .001) and speech recognition scores (r = .35, p = .007).

Conclusion Given significant correlations between Telislife scores and both speech recognition and quality of life and given its short form, the Telislife questionnaire appears to be a reliable tool to evaluate cochlear implant outcomes in clinical practice.

To review the longitudinal trajectories - and the factors influencing their development - of mental health problems in children with neurodevelopmental disabilities. Systematic review methods were employed. Searches of six databases used keywords and MeSH terms related to children with neurodevelopmental disabilities, mental health problems, and longitudinal research. After the removal of duplicates, reviewers independently screened records for inclusion, extracted data (outcomes and influencing factors), and evaluated the risk of bias. Findings were tabulated and synthesized using graphs and a narrative. Searches identified 94,662 unique records, from which 49 publications were included. The median publication year was 2015. Children with attention deficit hyperactivity disorder were the most commonly included population in retrieved studies. In almost 50% of studies, trajectories of mental health problems changed by &lt; 10% between the first and last time point. Despite multiple studies reporting longitudinal trajectories of mental health problems, greater conceptual clarity and consideration of the measures included in research is needed, along with the inclusion of a more diverse range of populations of children with neurodevelopmental disabilities.

Previous research has shown deficits in vocal emotion recognition in sub-populations of individuals with hearing loss, making this a high priority research topic. However, previousresearch has only examined vocal emotion recognition using verbal material, in which emotions are expressed through emotional prosody. There is evidence that older individualswith hearing loss suffer from deficits in general prosody recognition, not specific to emotionalprosody. No study has examined the recognition of non-verbal vocalization, which constitutes another important source for the vocal communication of emotions. It might be thecase that individuals with hearing loss have specific difficulties in recognizing emotionsexpressed through prosody in speech, but not non-verbal vocalizations. We aim to examinewhether vocal emotion recognition difficulties in middle- aged-to older individuals with sensorineural mild-moderate hearing loss are better explained by deficits in vocal emotion recognition specifically, or deficits in prosody recognition generally by including both sentencesand non-verbal expressions. Furthermore a, some of the studies which have concluded thatindividuals with mild-moderate hearing loss have deficits in vocal emotion recognition abilityhave also found that the use of hearing aids does not improve recognition accuracy in thisgroup. We aim to examine the effects of linear amplification and audibility on the recognitionof different emotions expressed both verbally and non-verbally. Besides examining accuracy for different emotions we will also look at patterns of confusion (which specific emotionsare mistaken for other specific emotion and at which rates) during both amplified and nonamplified listening, and we will analyze all material acoustically and relate the acoustic content to performance. Together these analyses will provide clues to effects of amplification onthe perception of different emotions. For these purposes, a total of 70 middle-aged-olderindividuals, half with mild-moderate hearing loss and half with normal hearing will perform acomputerized forced-choice vocal emotion recognition task with and without amplification

Few studies have examined which acoustic features of speech can be used to distinguish between different emotions, and how combinations of acoustic parameters contribute to identification of emotions. The aim of the present study was to investigate which acoustic parameters in Swedish speech are most important for differentiation between, and identification of, the emotions anger, fear, happiness, sadness, and surprise in Swedish sentences. One-way ANOVAs were used to compare acoustic parameters between the emotions and both simple and multiple logistic regression models were used to examine the contribution of different acoustic parameters to differentiation between emotions. Results showed differences between emotions for several acoustic parameters in Swedish speech: surprise was the most distinct emotion, with significant differences compared to the other emotions across a range of acoustic parameters, while anger and happiness did not differ from each other on any parameter. The logistic regression models showed that fear was the best-predicted emotion while happiness was most difficult to predict. Frequency- and spectral-balance-related parameters were best at predicting fear. Amplitude- and temporal-related parameters were most important for surprise, while a combination of frequency-, amplitude- and spectral balance-related parameters are important for sadness. Assuming that there are similarities between acoustic models and how listeners infer emotions in speech, results suggest that individuals with hearing loss, who lack abilities of frequency detection, may compared to normal hearing individuals have difficulties in identifying fear in Swedish speech. Since happiness and fear relied primarily on amplitude- and spectral-balance-related parameters, detection of them are probably facilitated more by hearing aid use.

BackgroundThe impact of hearing impairment is typically studied in terms of its effects on speech perception, yet this fails to account for the interactive nature of communication. Recently, there has been a move towards studying the effects of age-related hearing impairment on interaction, often using referential communication tasks; however, little is known about how interaction in these tasks compares to everyday communication. AimsTo investigate utterances and requests for clarification used in one-to-one conversations between older adults with hearing impairment and younger adults without hearing impairment, and between two younger adults without hearing impairment. Methods & ProceduresA total of 42 participants were recruited to the study and split into 21 pairs, 10 with two younger adults without hearing impairment and 11 with one younger adult without hearing impairment and one older participant with age-related hearing impairment (hard of hearing). Results from three tasks-spontaneous conversation and two trials of a referential communication task-were compared. A total of 5 min of interaction in each of the three tasks was transcribed, and the frequency of requests for clarification, mean length of utterance and total utterances were calculated for individual participants and pairs. Outcomes & ResultsWhen engaging in spontaneous conversation, participants made fewer requests for clarification than in the referential communication, regardless of hearing status/age (p & LE; 0.012). Participants who were hard of hearing made significantly more requests for clarification than their partners without hearing impairment in only the second trial of the referential communication task (U = 25, p = 0.019). Mean length of utterance was longer in spontaneous conversation than in the referential communication task in the pairs without hearing impairment (p & LE; 0.021), but not in the pairs including a person who was hard of hearing. However, participants who were hard of hearing used significantly longer utterances than their partners without hearing impairment in the spontaneous conversation (U = 8, p &lt; 0.001) but not in the referential communication tasks. Conclusions & ImplicationsThe findings suggest that patterns of interaction observed in referential communication tasks differ to those observed in spontaneous conversation. The results also suggest that fatigue may be an important consideration when planning studies of interaction that use multiple conditions of a communication task, particularly when participants are older or hard of hearing. WHAT THIS PAPER ADDSWhat is already known on this subjectAge-related hearing impairment is known to affect communication; however, the majority of studies have focused on its impact on speech perception in controlled conditions. This indicates little about the impact on everyday, interactive, communication. What this study adds to the existing knowledgeWe investigated utterance length and requests for clarification in one-to-one conversations between pairs consisting of one older adult who is hard of hearing and one younger adult without hearing impairment, or two younger adults without hearing impairment. Results from three tasks (two trials of a referential communication task and spontaneous conversation) were compared. The findings demonstrated a significant effect of task type on requests for clarification in both groups. Furthermore, in spontaneous conversation, older adults who were hard of hearing used significantly longer utterances than their partners without hearing impairment. This pattern was not observed in the referential communication task. What are the potential or actual clinical implications of this work?These findings have important implications for generalizing results from controlled communication tasks to more everyday conversation. Specifically, they suggest that the previously observed strategy of monopolizing conversation, possibly as an attempt to control it, may be more frequently used by older adults who are hard of hearing in natural conversation than in a more contrived communication task.

Emerging technology for public transportation is often not fully aligned with an inclusive design strategy. Many people with intellectual disability experience their needs and desires not being fully considered. Responding to this problem, the purpose of this study is to investigate how children with mild intellectual disability experience self-driving buses. On each bus, a person called "safety driver" monitors the ride and takes control if a problematic situation arises. The purpose is also to investigate what roles support persons and safety drivers play. In addition, the research aims to propose improvements in how the design of these self-driving buses can better motivate children with intellectual disability to use them in support of their agency. To address this, we arranged and studied seven rides on self-driving buses, for 16 children diagnosed to have mild intellectual disability, and their support persons. Interviews with the children were held after the rides, and both the rides and interviews were video recorded. The analysis was in part inductive but also employed a theory based on motivation: self-determination theory. For several children, the bus worked as a vehicle for a social sightseeing tour of the local environment, and the current design did not hinder such an experience. Overall, many of the children had a positive experience, but there is room for improvement regarding the design of the buses. Some children expressed curiosity and a few frustrations with how the bus behaved in traffic. For instance, it was difficult for the children to understand why the bus braked for things that were hard for them to perceive. From observation, it appears that the accompanying support person and safety driver played an important role in making children safe and shaping the social environment on the bus. The support persons were also essential for some children to ride the bus at all. The safety driver provided the children with information about how the bus worked. Both the safety driver and the support person had a positive impact on the children's experience. To meet the children's needs and skills, and to improve their motivation for riding the buses again, the buses need to decelerate less abruptly, have easier and consistently designed seatbelts, and communicate what they do, see, and signal more clearly. We argue that further studies at this level of detail are crucial to ensure that new technologies are indeed designed for everyone.

BackgroundThere is a need for an instrument to measure participation and independence in children with disabilities. FUNDES-Child-SE has its origin in the participation questionnaire Child and Adolescent Scale of Participation.AimsTest the psychometric properties of internal consistency and test-retest reliability.Material and methodsThis cross-sectional study included caregivers of 163 children with disability aged 6-18 years, 59 of whom were also included in the test-retest study. Descriptive statistics were used to evaluate the proportions of valid ratings. Internal consistency and test-retest reliability were tested through Cronbachs alpha and the intra-class correlation coefficient.ResultsThe amount of not relevant/not applicable ratings was substantial but varied between items and subdomains. Internal consistency was acceptable (0.8-0.95), and the test-retest was marginal to excellent (0.73-0.95).ConclusionsThe reliability together with the content validity support the use of the FUNDES-Child-SE to measure participation and independence in children with disabilities. However, results should be interpreted with caution due to the small sample size and possible selection bias. Modifications to reduce the not relevant/not applicable responses should be investigated together with the instruments responsiveness.SignificanceFUNDES-Child-SE can be used to facilitate a discussion of participation and independence and to plan interventions in a habilitation setting.

Full delaktighet i föreningar och i beslutsfattande processer för alla människor på alla nivåer anses vara eftersträvansvärt av internationella konventioner. Forskning visar dock att människor med intellektuell funktionsnedsättning upplever många inskränkningar i delaktigheten inklusive i delaktigheten i beslutsfattande processer. Det finns väldigt lite forskning som undersöker gemensamt beslutsfattande hos personer med intellektuell funktionsnedsättning. Syftet med den här studien är att bidra med fördjupad kunskap kring hur personer med intellektuell funktionsnedsättning upplever delaktigheten i beslutsfattande processer för att för att kunna förstå främjande faktorer. Kontexten för studien är intresseföreningar som har medlemmar och styrelseledamöter med intellektuell funktionsnedsättning, då föreningar tillhandahåller en bred mångfald av möjligheter för delaktighet i beslutsfattandet. Studien utgår ifrån följande frågeställningar utifrån ett biopsykosocialt perspektiv: Hur beskriver personer med intellektuell funktionsnedsättning den upplevda delaktigheten i beslutsfattande processer i en förening? Vilka faktorer för kognitiv tillgänglighet beskrivs som betydelsefulla för personer med IF? Studien utgår dessutom ifrån kritisk realism som vetenskapsteoretisk ansats. Metoden som används är kvalitativa intervjuer som analyseras med en innehållsanalys. Resultat som framkommer är att delaktigheten i beslutsfattande i de undersökta kontexterna upplevs ofta bra men att delaktighetsinskränkningar förekommer. Det finns ett flertal faktorer för kognitiv tillgänglighet som är betydelsefulla. 

The processing of a language involves a neural language network including temporal, parietal, and frontal cortical regions. This applies to spoken as well as signed languages. Previous research suggests that spoken language proficiency is associated with resting-state functional connectivity (rsFC) between language regions and other regions of the brain. Given the similarities in neural activation for spoken and signed languages, rsFC-behavior associations should also exist for sign language tasks. In this study, we explored the associations between rsFC and two types of linguistic skills in sign language: phonological processing skill and accuracy in elicited sentence production. Fifteen adult, deaf early signers were enrolled in a resting-state functional magnetic resonance imaging (fMRI) study. In addition to fMRI data, behavioral tests of sign language phonological processing and sentence reproduction were administered. Using seed-to-voxel connectivity analysis, we investigated associations between behavioral proficiency and rsFC from language-relevant nodes: bilateral inferior frontal gyrus (IFG) and posterior superior temporal gyrus (STG). Results showed that worse sentence processing skill was associated with stronger positive rsFC between the left IFG and left sensorimotor regions. Further, sign language phonological processing skill was associated with positive rsFC from right IFG to middle frontal gyrus/frontal pole although this association could possibly be explained by domain-general cognitive functions. Our findings suggest a possible connection between rsFC and developmental language outcomes in deaf individuals.

Objective: The aim of the present study was to assess the validity of the Ease of Language Understanding (ELU) model through a statistical assessment of the relationships among its main parameters: processing speed, phonology, working memory (WM), and dB Speech Noise Ratio (SNR) for a given Speech Recognition Threshold (SRT) in a sample of hearing aid users from the n200 database.

Methods: Hearing aid users were assessed on several hearing and cognitive tests. Latent Structural Equation Models (SEMs) were applied to investigate the relationship between the main parameters of the ELU model while controlling for age and PTA. Several competing models were assessed.

Results: Analyses indicated that a mediating SEM was the best fit for the data. The results showed that (i) phonology independently predicted speech recognition threshold in both easy and adverse listening conditions and (ii) WM was not predictive of dB SNR for a given SRT in the easier listening conditions (iii) processing speed was predictive of dB SNR for a given SRT mediated via WM in the more adverse conditions.

Conclusion: The results were in line with the predictions of the ELU model: (i) phonology contributed to dB SNR for a given SRT in all listening conditions, (ii) WM is only invoked when listening conditions are adverse, (iii) better WM capacity aids the understanding of what has been said in adverse listening conditions, and finally (iv) the results highlight the importance and optimization of processing speed in conditions when listening conditions are adverse and WM is activated.

Background

Adults with attention deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD) face multiple challenges in obtaining and maintaining employment.

Aims

To identify and describe how adults with ADHD or ASD experienced their ability to work and what factors affected their ability to find a sustainable work situation over time.

Methods

Individual in-depth interviews were performed with 20 purposively sampled participants with ADHD/ASD. Data were analysed inductively using reflexive thematic analysis.ResultsThree themes were identified, describing (1) one’s own cognitive abilities and challenges, (2) enablement by flexibility and acceptance in the work environment, and (3) accumulated stress that makes the work situation unsustainable over time.

Conclusions

Over time, a lack of continuity and predictability of support measures caused great stress and exhaustion, with severe consequences for working life and in life in general. Adaptations needed to be individually tailored and include nonoccupational factors.

Significance

The study shows that adults with ADHD/ASD need long-term interventions that flexibly adapt to individual needs, as they vary over time. The findings suggest that occupational therapists and other health care providers, employers, employment services and other involved agencies should pay a greater deal of attention to stability and predictability over time.

Background: Different barriers may hinder children with developmental disabilities (DD) from having a voice in research and clinical interventions concerning fundamentally subjective phenomena, such as participation. It is not well-investigated if video communication tools have the potential to reduce these barriers. Aim: This study investigated the feasibility of administering a self-rating instrument measuring participation, Picture My Participation (PmP), via a video communication tool (Zoom), to children with DD. Materials and methods: PmP was administered to 17 children with DD (mean age 13 years). The pictorial representations of activities and response options in PmP were displayed in a shared PowerPoint presentation, enabling nonverbal responses with the annotate function in Zoom. Child and interviewer perceptions of the interview were measured through questionnaires developed for the purpose. Results: All the children completed the interview. Most PmP questions were answered, and no adverse events were registered. Technical issues could generally be solved. No special training or expensive equipment was needed for the interviews. Conclusion: Interviewer-guided self-ratings of participation and related constructs through video communication may be  a feasible procedure to use with children with DD from age 11. Significance: Offering video communication may increase children’s chances to contribute subjective experiences in research and clinical practice.

The current study investigated the structural validity and internal consistency of the Strengths and Stressors (SSF) questionnaire. The SSF is used in Swedish habilitation services to measure the positive and negative consequences that the fostering of a child with a developmental disability can have on family functioning in six domains: parent's feelings and attitudes, social life, family finances, relationship to the other parent, siblings, and professional support. The proposed six-factor model was tested with confirmatory factor analysis with data collected from 291 parents of children with developmental disabilities. The six-factor model had an acceptable fit according to most fit indices, but two items were non-significant. Overall, the internal consistency was acceptable or good. The SSF, with the proposed six-factor solution, can be a useful tool when assessing parental perspectives on the impacts of having a child with a developmental disability in clinical settings and research.

TIME is a highly abstract concept and prevalent in languages worldwide. Cross-cultural and cross-linguistic research suggests that TIME is embodied dissimilarly in different languages. Still the literature has not received sufficient attention in examining the differences. This study aimed to identify and compare how TIME is metaphorically represented and embodied worldwide. We investigated 14 languages; Arabic, Assamese, Chinese, English, Finnish, French, German, Japanese, Kikuyu, Persian, Polish, Russian, Spanish, and Swedish, which represent nine language families. The metaphors were categorized conceptually as TIME IS AN ORGANISM, TIME IS MOTION, TIME IS SPACE, and TIME IS A VALUABLE COMMODITY. We employed a two-part paper-based task. The first part consisted of generation of metaphor items and the second part consisted of a valence rating task. The key variables considered were metaphor category and language family while controlling for demographic variables such as gender, age and handedness. Data from 513 participants were collected. Results showed a significant association between language categories and the valences of time metaphors. The data of this study suggest that within the languages of a certain category, there might be some similarity between the valences of words that are used to realize a given conceptual metaphor.

Kapitlet handlar om hur kommunikation med några personer som har svåra förvärvade hjärnskador och som inte kommunicerar verbalt går till. Avsaknad av tal, afasi, återfinns hos personer med svåra hjärnskador, oavsett om hjärnskadan är en följd av sjukdom eller skada. Inledningsvis beskrivs förekomst av hjärnskada. Därefter tas begreppet kommunikation upp. Tonvikten läggs på dialogen och samspelet mellan personerna. Kognitiva förmågor som minne och språk kommer att behandlas kortfattat. Huvuddelen av kapitlet består av fyra personbeskrivningar Berit, Ann, Bertil och Karin. Varje personbeskrivning avslutas med en analys av vad som underlättar respektive hindrar kommunikationen. Även om beskrivningarna handlar om personer med förvärvad hjärnskada går resultaten att generalisera till andra grupper, till exempel personer med flerfunktionsnedsättning (intellektuell funktionsnedsättning och omfattande motorisk funktionsnedsättning) och personer med demens. Syftet med kapitlet är dels att ge läsaren en orientering om hur viktig kommunikationen är i det dagliga omsorgsarbetet, dels att beskriva metoder för hur kommunikationen kan gå till när den ena av parterna inte kan tala.

Prospective memory (PM) or memory for intentions is difficult for people with intellectualdisability (ID). PM has been studied in young people with Down syndrome (Godfrey &Lee, 2020) but less is known about PM in adults with unknown or other causes of ID.Storing the content of the intention and retrieval at the appropriate event load onretrospective memory and executive functions. No difference have been found betweensubjective and more objective measures of PM in the ID population (Levén m.fl., 2011).Subjective experience of perceptual impairments, e.g., hard of hearing, will be investigatedas age-related hearing loss occurs early in the ID group and hearing can benefit PM. Themore objective measure of PM is based on the procedure used in the Betula project onmemory function and ageing in Sweden. As PM task the participant get the instruction toremind the researcher about a paper to sign when the tests are finished. In case this isforgotten the participant is asked if there was something else they should do. If no responsewas given the cue; Were you not supposed to remind me of something? was provided.Subjects were not told that this was a memory test. The SDQ instrument (Goodman, 1997)will give a general description of the individual, inhibition will be rated with the VIMIinstrument, digit span rates working memory capacity, and the subjective experience ofretrospective and prospective memory is rated with PRMQ (Rönnlund m.fl., 2011). 

Teaching phoneme awareness to children at risk for early reading difficulties has been recognized as successful in several studies. In this randomized controlled trial (RCT)-study, we add to this research by optimizing core procedural as well as teaching components in a phonics-directed intervention and extend the RCT reading intervention research into a semi-transparent language context. The aim of the present study was to evaluate the effects of a novel Swedish intensive phonics program. This randomized controlled pre-test and post-test intervention study targeted second-grade students with early reading difficulties. Students were identified by a repeated screening procedure and allocated to intervention (n = 34) and control (n = 34) conditions. A 9-week intensive phonics-based program was administrated one-to-one, by special education teachers in Swedish mainstream elementary schools. Results show an improvement in the intervention group, compared with the controls on all outcome measures. Findings indicate that the supplementary phonics program, delivered with high intensity, can significantly increase word reading skills and reading comprehension in second-grade students with early reading difficulties.

What causes interference in short-term memory? We report the novel finding that immediate memory for visually-presented verbal items is sensitive to disruption from task-irrelevant vibrotactile stimuli. Specifically, short-term memory for a visual sequence is disrupted by a concurrently presented sequence of vibrations, but only when the vibrotactile sequence entails change (when the sequence “jumps” between the two hands). The impact on visual-verbal serial recall was similar in magnitude to that for auditory stimuli (Experiment 1). Performance of the missing item task, requiring recall of item-identity rather than item-order, was unaffected by changing-state vibrotactile stimuli (Experiment 2), as with changing-state auditory stimuli. Moreover, the predictability of the changing-state sequence did not modulate the magnitude of the effect, arguing against an attention-capture conceptualisation (Experiment 3). Results support the view that interference in short-term memory is produced by conflict between incompatible, amodal serial-ordering processes (interference-by-process) rather than interference between similar representational codes (interference-by-content).

Touch is a powerful communication tool, but we have a limited understanding of the role played by particular physical features of interpersonal touch communication. In this study, adults living in Sweden performed a task in which messages (attention, love, happiness, calming, sadness, and gratitude) were conveyed by a sender touching the forearm of a receiver, who interpreted the messages. Two experiments (N = 32, N = 20) showed that within close relationships, receivers could identify the intuitive touch expressions of the senders, and we characterized the physical features of the touches associated with successful communication. Facial expressions measured with electromyography varied by message but were uncorrelated with communication performance. We developed standardized touch expressions and quantified the physical features with 3D hand tracking. In two further experiments (N = 20, N = 16), these standardized expressions were conveyed by trained senders and were readily understood by strangers unacquainted with the senders. Thus, the possibility emerges of a standardized, intuitively understood language of social touch.

Research concerned with children and young people who have neurodevelopmental disabilities (ND) in relation to early language acquisition usually involves comparisons with matched group(s) of typically developing individuals. In these studies, several important and complex issues need to be addressed. Three major issues are related to: (1) the choice of a variables on which to carry out group matching; (2) recruiting children into the study; and (3) the statistical analysis of the data. To assist future research on this topic, we discuss each of these three issues and provide recommendations about what we believe to be the best course of action. To provide a comprehensive review of the methodological issues, we draw on research beyond the topic of early language acquisition. Our overall aim is to contribute to research that considers questions about delay or differences in development patterns of development and about identifying potentially causal variables.

The structure and development of executive functioning (EF) have been intensively studied in typically developing populations, with little attention given to those with Special Educational Needs (SEN). This study addresses this by comparing the EF structure of 132 adolescents (11-14 years-old) with SEN and 138 adolescents not requiring additional support (Non-SEN peers). Participants completed verbal and non-verbal assessments of key components of EF: inhibition, working memory and switching. Confirmatory Factor Analysis on each group tested one-, two- and three-factor models of EF. In both groups, there was statistical support for the fit of one- and two-factor models with no model being clearly better than the others; there was little support for three-factor models. Parsimony suggests that the one-factor model best represents the structure of EF. In light of our results, the implications for the nature of EF in early adolescence in both SEN and Non-SEN groups are discussed.

The aim of the current study was to investigate whether task-evoked pupillary responses measured during encoding, individual working memory capacity and noise reduction in hearing aids were associated with the likelihood of subsequently recalling an item in an auditory free recall test combined with pupillometry. Participants with mild to moderately severe symmetrical sensorineural hearing loss (n = 21) were included. The Sentence-final Word Identification and Recall (SWIR) test was administered in a background noise composed of sixteen talkers with noise reduction in hearing aids activated and deactivated. The task-evoked peak pupil dilation (PPD) was measured. The Reading Span (RS) test was used as a measure of individual working memory capacity. Larger PPD at a single trial level was significantly associated with higher likelihood of subsequently recalling a word, presumably reflecting the intensity of attention devoted during encoding. There was no clear evidence of a significant relationship between working memory capacity and subsequent memory recall, which may be attributed to the SWIR test and RS test being administered in different modalities, as well as differences in task characteristics. Noise reduction did not have a significant effect on subsequent memory recall. This may be due to the background noise not having a detrimental effect on attentional processing at the favorable signal-to-noise ratio levels at which the test was conducted.

Face-to-face communication is one of the most common means of communication in daily life. We benefit from both auditory and visual speech signals that lead to better language understanding. People prefer face-to-face communication when access to auditory speech cues is limited because of background noise in the surrounding environment or in the case of hearing impairment. We demonstrated that an early, short period of exposure to audiovisual speech stimuli facilitates subsequent auditory processing of speech stimuli for correct identification, but early auditory exposure does not. We called this effect "perceptual doping" as an early audiovisual speech stimulation dopes or recalibrates auditory phonological and lexical maps in the mental lexicon in a way that results in better processing of auditory speech signals for correct identification. This short opinion paper provides an overview of perceptual doping and how it differs from similar auditory perceptual aftereffects following exposure to audiovisual speech materials, its underlying cognitive mechanism, and its potential usefulness in the aural rehabilitation of people with hearing difficulties.

Individuals with intellectual disability (ID) have difficulties with decoding and reading comprehension. However, studies focussing on why these difficulties occur are very sparse, and the existing literature has found conflicting results. This thesis investigated the development of reading abilities and the concurrent cognitive, linguistic, and environmental predictors of decoding and reading comprehension in Swedish adolescents with ID of unknown aetiology. In addition, this thesis evaluated the applicability of one of the most commonly used theoretical frameworks of reading comprehension: the Simple View of Reading (SVR). The results showed that the development of reading abilities in adolescents with ID is in line with the model of developmental delay. This means that the development of reading abilities is not qualitatively different from typical reading development, but the rate is slower. Further, it means that the pattern of concurrent predictors is similar to the pattern found in a younger typically developing population. In Swedish adolescents with ID decoding is predicted by phonological awareness and rapid automatized naming (RAN), and reading comprehension is predicted by decoding, vocabulary, and phonological executive-loaded working memory (ELWM). This thesis also found that the developmental trajectory of decoding plateaus at a mental age of 8:9 years, while it is expected in typically developing children that decoding ability continues to increase until early adolescence. The explanation for this early plateau could be either cognitive or educational, but most likely a combination of both. Lastly, the results from this thesis also suggest that the SVR is not sufficient for explaining reading comprehension in adolescents with ID. Instead, a combination of the SVR and the Lexical Quality Hypothesis (LQH) is suggested as a successful way of explaining the variance in reading comprehension. Taken together, the results from this thesis implies that reading instruction and interventions originally developed for typically developing children is likely to be effective for individuals with ID.  

Importance  About 20% to 30% of people with schizophrenia have psychotic symptoms that do not respond adequately to first-line antipsychotic treatment. This clinical presentation, chronic and highly disabling, is known as treatment-resistant schizophrenia (TRS). The causes of treatment resistance and their relationships with causes underlying schizophrenia are largely unknown. Adequately powered genetic studies of TRS are scarce because of the difficulty in collecting data from well-characterized TRS cohorts.

Objective  To examine the genetic architecture of TRS through the reassessment of genetic data from schizophrenia studies and its validation in carefully ascertained clinical samples.

Design, Setting, and Participants  Two case-control genome-wide association studies (GWASs) of schizophrenia were performed in which the case samples were defined as individuals with TRS (n = 10 501) and individuals with non-TRS (n = 20 325). The differences in effect sizes for allelic associations were then determined between both studies, the reasoning being such differences reflect treatment resistance instead of schizophrenia. Genotype data were retrieved from the CLOZUK and Psychiatric Genomics Consortium (PGC) schizophrenia studies. The output was validated using polygenic risk score (PRS) profiling of 2 independent schizophrenia cohorts with TRS and non-TRS: a prevalence sample with 817 individuals (Cardiff Cognition in Schizophrenia [CardiffCOGS]) and an incidence sample with 563 individuals (Genetics Workstream of the Schizophrenia Treatment Resistance and Therapeutic Advances [STRATA-G]).

Main Outcomes and Measures  GWAS of treatment resistance in schizophrenia. The results of the GWAS were compared with complex polygenic traits through a genetic correlation approach and were used for PRS analysis on the independent validation cohorts using the same TRS definition.

Results  The study included a total of 85 490 participants (48 635 [56.9%] male) in its GWAS stage and 1380 participants (859 [62.2%] male) in its PRS validation stage. Treatment resistance in schizophrenia emerged as a polygenic trait with detectable heritability (1% to 4%), and several traits related to intelligence and cognition were found to be genetically correlated with it (genetic correlation, 0.41-0.69). PRS analysis in the CardiffCOGS prevalence sample showed a positive association between TRS and a history of taking clozapine (r2 = 2.03%; P = .001), which was replicated in the STRATA-G incidence sample (r2 = 1.09%; P = .04).

Conclusions and Relevance  In this GWAS, common genetic variants were differentially associated with TRS, and these associations may have been obscured through the amalgamation of large GWAS samples in previous studies of broadly defined schizophrenia. Findings of this study suggest the validity of meta-analytic approaches for studies on patient outcomes, including treatment resistance.

This study reports the process and preliminary findings of rapid implementation oftelegenetic counseling in the context of Swedish healthcare and COVID-19 pandemic,from both a patient and a provider perspective. Fourty-nine patients and 6 healthcareprofessionals were included in this feasibility study of telegenetic counseling in aregional Department of Clinical Genetics in Sweden. Telegenetic counseling is heredefined as providing genetic counseling to patients by video (n =30) or telephone (n= 19) appointments. Four specific feasibility aspects were considered: acceptability,demand, implementation, and preliminary efficacy. Several measures were used includingthe Genetic Counseling Outcome Scale 24 (collected pre- and post-counseling); theTelehealth Usability Questionnaire; a short study specific evaluation and Visiba Careevaluations, all collected post-counseling. The measures were analyzed with descriptivestatistics and the preliminary results show a high level of acceptance and demand, fromboth patients and providers. Results also indicate successful initial implementation in theregional Department of Clinical Genetics and preliminary efficacy, as shown by significantclinically important improvement in patients’ empowerment levels.

Educational researchers have challenged Bandura’s prediction that self-efficacy beliefs tend to be established early in learning and that once set, self-efficacy beliefs persist unless a critical event causes them to be reevaluated. However, the results have been mixed in previous research, including being positive, negative, and unchanged. In response, we evaluated how 75 teachers (i.e., special educators) rate their teaching self-efficacy beliefs in motivating student reading and adapting reading instruction at two time points. All teachers taught students with an intellectual disability, communication difficulties, and poor reading skills. The teachers participated in a workshop to learn teaching reading strategies with apps under various conditions (comprehension strategies, phonemic strategies, or both comprehension and phonemic strategies). We analyzed teacher self-efficacy beliefs at two time points with a 12-week span (pre-and postintervention). First, we developed measures of teacher self-efficacy through confirmatory factor analyses. Next, we analyzed the data with multiple imputation and mixed linear regression with difference-in-differences (DiD). The results indicated no statistically significant treatment effect on teachers’ rating of their teaching self-efficacy beliefs. We conclude that our results agree with Bandura’s original prediction and thus, his social cognitive theory.

This is an empirical study, preceded by a corresponding review of the state of the art, to demonstrate that, as suggested by the notion of multimodal language processing in the ELU model, an intervention basedon training the connection between sign language and reading can be a very useful method to improve word reading among children who are def or hard of hearing who know sign language.

Objective: The current update of the Ease of Language Understanding (ELU) model evaluates the predictive and postdictive aspects of speech understanding and communication.

Design: The aspects scrutinised concern: (1) Signal distortion and working memory capacity (WMC), (2) WMC and early attention mechanisms, (3) WMC and use of phonological and semantic information, (4) hearing loss, WMC and long-term memory (LTM), (5) WMC and effort, and (6) the ELU model and sign language. Study Samples: Relevant literature based on own or others' data was used.

Results: Expectations 1-4 are supported whereas 5-6 are constrained by conceptual issues and empirical data. Further strands of research were addressed, focussing on WMC and contextual use, and on WMC deployment in relation to hearing status. A wider discussion of task demands, concerning, for example, inference-making and priming, is also introduced and related to the overarching ELU functions of prediction and postdiction. Finally, some new concepts and models that have been inspired by the ELU-framework are presented and discussed.

Conclusions: The ELU model has been productive in generating empirical predictions/expectations, the majority of which have been confirmed. Nevertheless, new insights and boundary conditions need to be experimentally tested to further shape the model.Keywords: Cognition; age-related hearing loss; dementia; ease of language understanding; effort; hearing impairment; speech in noise; working memory.

To conceptualize the communicative role of working memory (WM), the Ease-of-Language Understanding (ELU) model was proposed (e.g., Rönnberg, 2003; Rönnberg et al., 2008, 2013, 2019, 2020). The model states that ease of language understanding is determined by the speed and accuracy with which the signal is matched to existing multimodal language representations. When matching is fast and complete, language understanding is effortless; this process may be facilitated by predictions based on the contents of WM. However, when the contents of the language signal mismatches with existing representations, WM is triggered to access knowledge in semantic long-term memory (SLTM) and personal experience from episodic long-term memory (ELTM) – promoting inference-making and postdictions in WM. The interplay between WM and LTM is fundamental to language understanding; its efficiency becomes apparent in adverse conditions and its breakdown may explain cognitive decline and dementia. Empirical support, limitations, and future studies will be discussed.

The review gives an introductory description of the successive development of data patterns based on comparisons between hearing-impaired and normal hearing participants speech understanding skills, later prompting the formulation of the Ease of Language Understanding (ELU) model. The model builds on the interaction between an input buffer (RAMBPHO, Rapid Automatic Multimodal Binding of PHOnology) and three memory systems: working memory (WM), semantic long-term memory (SLTM), and episodic long-term memory (ELTM). RAMBPHO input may either match or mismatch multimodal SLTM representations. Given a match, lexical access is accomplished rapidly and implicitly within approximately 100-400 ms. Given a mismatch, the prediction is that WM is engaged explicitly to repair the meaning of the input - in interaction with SLTM and ELTM - taking seconds rather than milliseconds. The multimodal and multilevel nature of representations held in WM and LTM are at the center of the review, being integral parts of the prediction and postdiction components of language understanding. Finally, some hypotheses based on a selective use-disuse of memory systems mechanism are described in relation to mild cognitive impairment and dementia. Alternative speech perception and WM models are evaluated, and recent developments and generalisations, ELU model tests, and boundaries are discussed.

Background It can be challenging for people with intellectual disabilities to convey their thoughts and opinions because of cognitive, speech and language impairments. Consequently, facilitating their ability to communicate using augmentative and alternative communication methods is essential. The picture-based framework Talking Mats has been applied in many studies and has been shown to be successful in facilitating communication and soliciting views from individuals with intellectual disabilities and communication difficulties. The aim of this study was to describe the views of students with intellectual disabilities and communication difficulties on speech and reading activities and to examine whether valence scores (from negative to positive) on these views were associated with performance on tests of their corresponding abilities. Methods This is a cross-sectional quantitative survey study. A group of 111 students with intellectual disabilities and communication difficulties aged 7–21 were interviewed about their speech and reading activities using the visual framework Talking Mats. Their answers were scored on a three-grade like-dislike continuum and were correlated with their results on adapted tests of the corresponding abilities. Findings The students expressed their views on speech and reading activities. The scored views on speech were positively associated with speech production, and the scored views on reading activities were positively related to reading ability. This suggests that their opinions as expressed through Talking Mats were consistent and reliable. Conclusions Most students with intellectual disabilities and communicative difficulties can reliably express their own opinions of their abilities when they are provided with a clear visual structure and pictorial support, such as Talking Mats. In this study, this was seen for students with a mild intellectual disability from age seven and onwards and for students with a more severe intellectual disability from 12 years of age and onwards.

Earlier research and reports from educational practice seem to suggest that teaching early literacy skills may facilitate speech-sound production in students with intellectual disabilities, but further research is needed to confirm a potential connection. This study investigated (1) the relationship between speech-sound production, phonological awareness, and letter-sound knowledge in students with intellectual disabilities and communication difficulties, and (2) to what degree phonological awareness and letter-sound knowledge explain the variance in speech-sound production over and above IQ and chronological age. A group of 116 students, aged 7–21, enrolled in Swedish compulsory schools for students with intellectual disabilities participated in this study. All had limited reading skills. The test results for phonological awareness, letter-sound knowledge, and speech-sound production had a wide range. The results showed that early literacy skills were moderately and significantly correlated with speech-sound production. After controlling for IQ and age in a regression model, the addition of phonological awareness and letter-sound knowledge explained 29% of the variance in speech-sound production. The results suggest that phonological awareness and letter-sound knowledge is associated with speech-sound production and that these associations are not explained by age or IQ. Further research on this group of students should aim to determine causal relationships, for instance, by investigating early reading intervention and the potential effect on speech-sound production.

The purpose of the study was to evaluate whether students with intellectual disabilities (ID) can improve their arithmetic skills by participating in an arithmetic intervention programme, theoretically founded on explicit instruction (EI) and administered via an application developed for tablet computers. The intervention study used a randomised controlled trial design (RCT) (n = 30, aged 10-16, 13 females) and lasted for up to 12 weeks. The results show that the intervention group significantly improved in arithmetic fact fluency compared to the controls and the effects remained six months after the intervention. The effects were larger for subtraction than for addition, and this difference remained six months later. These results suggest that mathematics applications based on explicit instruction can be an effective way of teaching arithmetic facts to youth with mild ID.

Introduction

Our aim was to, firstly, identify characteristics at first-episode of psychosis that are associated with later antipsychotic treatment resistance (TR) and, secondly, to develop a parsimonious prediction model for TR.

Methods

We combined data from ten prospective, first-episode psychosis cohorts from across Europe and categorised patients as TR or non-treatment resistant (NTR) after a mean follow up of 4.18 years (s.d. = 3.20) for secondary data analysis. We identified a list of potential predictors from clinical and demographic data recorded at first-episode. These potential predictors were entered in two models: a multivariable logistic regression to identify which were independently associated with TR and a penalised logistic regression, which performed variable selection, to produce a parsimonious prediction model. This model was internally validated using a 5-fold, 50-repeat cross-validation optimism-correction.

Results

Our sample consisted of N = 2216 participants of which 385 (17 %) developed TR. Younger age of psychosis onset and fewer years in education were independently associated with increased odds of developing TR. The prediction model selected 7 out of 17 variables that, when combined, could quantify the risk of being TR better than chance. These included age of onset, years in education, gender, BMI, relationship status, alcohol use, and positive symptoms. The optimism-corrected area under the curve was 0.59 (accuracy = 64 %, sensitivity = 48 %, and specificity = 76 %).

Implications

Our findings show that treatment resistance can be predicted, at first-episode of psychosis. Pending a model update and external validation, we demonstrate the potential value of prediction models for TR.

This study investigated if the language profiles of prelingually deaf children with bilateral cochlear implants (CIs) and children with typical hearing (TH) matched on their quantitative score on clinical spoken expressive language tasks differed in terms of sentence complexity, sentence length, and severity of grammatical errors. No significant differences were found between the groups in terms of (1) proportion of simple, conjoined, and complex sentences; (2) mean length of utterance based on words and syllables; and (3) proportion of local and global grammatical errors. The results indicate that the quantitative scores on the clinical spoken expressive language tasks are related to similar spoken language profiles in children with CIs and children with TH. These findings suggest that these tests can be used for meaningful comparisons of expressive spoken language skills. However, more studies are needed on the real-life expressive language skills of children with CIs, as clinical tests often rely on one specific modality (in this study: spoken language) and might therefore not accurately represent the language skills of the children.

Purpose: Kenett et al. (2013) report that the sematic networks, measured by using an oral semantic fluency task, of children with cochlear implants (CI) are less structured compared to the sematic networks of children with typical hearing (TH). This study aims to evaluate if such differences are only evident if children with CI are compared to children with TH matched on chronological age, or also if they are compared to children with TH matched on hearing age. Method: The performance of a group of children with CI on a verbal fluency task was compared to the performance of a group of chronological-age matched children with TH. Subsequently, computational network analysis was used to compare the semantic network structure of the groups. The same procedure was applied to compare a group of children with CI to a group of hearing-age matched children with TH. Results: The children with CI perform on the same level on an oral semantic verbal fluency task as the children with TH matched on hearing age. There are significant differences in terms of the structure of the semantic network between the groups. The magnitude of these differences is very small and they are non-significant for a proportion of nodes included in the bootstrap analysis. This indicates that there is no true difference between the networks. Hearing age, but not age at implantation was found to be significantly positively correlated with semantic verbal fluency performance for the children with CI. Conclusions: The results from the current study indicate that length of exposure to the tested language is an important factor for the structure of the semantic network and the performance on a semantic verbal fluency task for children with CI. Further studies are needed to explore the role of the accessibility of the language input for the development of semantic networks of children with CI.
