    Auditory Brainstem Response Improvements in Hyperbillirubinemic Infants2016Ingår i: JOURNAL OF AUDIOLOGY AND OTOLOGY, ISSN 2384-1621, Vol. 20, nr 1, s. 13-16Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and Objectives: Hyperbillirubinemia in infants have been associated with neuronal damage including in the auditory system. Some researchers have suggested that the bilirubin-induced auditory neuronal damages may be temporary and reversible. This study was aimed at investigating the auditory neuropathy and reversibility of auditory abnormalities in hyperbillirubinemic infants. Subjects and Methods: The study participants included 41 full term hyperbilirubinemic infants (mean age 39.24 days) with normal birth weight (3,2003,700 grams) that admitted in hospital for hyperbillirubinemia and 39 normal infants (mean age 35.54 days) without any hyperbillirubinemia or other hearing loss risk factors for ruling out maturational changes. All infants in hyperbilirubinemic group had serum bilirubin level more than 20 milligram per deciliter and undergone one blood exchange transfusion. Hearing evaluation for each infant was conducted twice: the first one after hyperbilirubinemia treatment and before leaving hospital and the second one three months after the first hearing evaluation. Hearing evaluations included transient evoked otoacoustic emission (TEOAE) screening and auditory brainstem response (ABR) threshold tracing. Results: The TEOAE and ABR results of control group and TEOAE results of the hyperbilirubinemic group did not change significantly from the first to the second evaluation. However, the ABR results of the hyperbilirubinemic group improved significantly from the first to the second assessment (p=0.025). Conclusions: The results suggest that the bilirubin induced auditory neuronal damage can be reversible over time so we suggest that infants with hyperbilirubinemia who fail the first hearing tests should be reevaluated after 3 months of treatment.

    Pain and activity limitations in women and men with contemporary treated early RA compared to 10 years ago: the Swedish TIRA project2015Ingår i: Scandinavian Journal of Rheumatology, ISSN 0300-9742, E-ISSN 1502-7732, Vol. 44, nr 4, s. 259-264Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To study differences regarding pain and activity limitations during the 3 years following diagnosis in women and men with contemporary treated early RA compared with their counterparts who were diagnosed 10 years earlier. Method: This study was based on patients recruited to the Early Intervention in RA (TIRA) project. In the first cohort (TIRA-1) 320 patients were included in time for diagnosis during 1996-1998 and 463 patients were included in the second cohort (TIRA-2) during 2006-2009. Disease activity, pain intensity (Visual Analogue Scale, VAS), bodily pain (BP) in the 36-item Short Form Health Survey (SF-36), activity limitations (Health Assessment Questionnaire, HAQ), and medication were reported at inclusion and at follow-up after 1, 2, and 3 years. Results: Disease activity, pain, and activity limitations were pronounced at inclusion across both genders and in both cohorts, with some improvement observed during the first year after diagnosis. Disease activity did not differ between cohorts at inclusion but was significantly lower at the follow-ups in the TIRA-2 cohort, in which the patients were prescribed traditional disease-modifying anti-rheumatic drugs (DMARDs) and biological agents more frequently. In TIRA-2, patients reported significantly lower pain and activity limitations at all follow-ups, with men reporting lower pain than women. Women reported significantly higher activity limitations at all time points in TIRA-2. Conclusions: Pain and activity limitations were still pronounced in the contemporary treated early RA cohort compared with their counterparts diagnosed 10 years earlier and both of these factors need to be addressed in clinical settings.

    Studying Disability Related Terms with Swe-Clarin Resources2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    In Swedish, as in other languages, the words used to refer to disabilities and people with disabilities are manifold. Recommendations as to which terms to use have been changed several times over the last hundred years. In this exploratory paper we have used textual resources provided by Swe-Clarin to study such changes quantitatively. We demonstrate that old and new recommendations co-exist for long periods of time, and that usage sometimes converges.

    Neural Representation Enhanced for Speech and Reduced for Background Noise With a Hearing Aid Noise Reduction Scheme During a Selective Attention Task2020Ingår i: Frontiers in Neuroscience, ISSN 1662-4548, E-ISSN 1662-453X, Vol. 14, artikel-id 846Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives Selectively attending to a target talker while ignoring multiple interferers (competing talkers and background noise) is more difficult for hearing-impaired (HI) individuals compared to normal-hearing (NH) listeners. Such tasks also become more difficult as background noise levels increase. To overcome these difficulties, hearing aids (HAs) offer noise reduction (NR) schemes. The objective of this study was to investigate the effect of NR processing (inactive, where the NR feature was switched off,vs.active, where the NR feature was switched on) on the neural representation of speech envelopes across two different background noise levels [+3 dB signal-to-noise ratio (SNR) and +8 dB SNR] by using a stimulus reconstruction (SR) method. Design To explore how NR processing supports the listeners selective auditory attention, we recruited 22 HI participants fitted with HAs. To investigate the interplay between NR schemes, background noise, and neural representation of the speech envelopes, we used electroencephalography (EEG). The participants were instructed to listen to a target talker in front while ignoring a competing talker in front in the presence of multi-talker background babble noise. Results The results show that the neural representation of the attended speech envelope was enhanced by the active NR scheme for both background noise levels. The neural representation of the attended speech envelope at lower (+3 dB) SNR was shifted, approximately by 5 dB, toward the higher (+8 dB) SNR when the NR scheme was turned on. The neural representation of the ignored speech envelope was modulated by the NR scheme and was mostly enhanced in the conditions with more background noise. The neural representation of the background noise was modulated (i.e., reduced) by the NR scheme and was significantly reduced in the conditions with more background noise. The neural representation of the net sum of the ignored acoustic scene (ignored talker and background babble) was not modulated by the NR scheme but was significantly reduced in the conditions with a reduced level of background noise. Taken together, we showed that the active NR scheme enhanced the neural representation of both the attended and the ignored speakers and reduced the neural representation of background noise, while the net sum of the ignored acoustic scene was not enhanced. Conclusion Altogether our results support the hypothesis that the NR schemes in HAs serve to enhance the neural representation of speech and reduce the neural representation of background noise during a selective attention task. We contend that these results provide a neural index that could be useful for assessing the effects of HAs on auditory and cognitive processing in HI populations.

    Effects of Hearing Aid Noise Reduction on Early and Late Cortical Representations of Competing Talkers in Noise2021Ingår i: Frontiers in Neuroscience, ISSN 1662-4548, E-ISSN 1662-453X, Vol. 15, artikel-id 636060Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives Previous research using non-invasive (magnetoencephalography, MEG) and invasive (electrocorticography, ECoG) neural recordings has demonstrated the progressive and hierarchical representation and processing of complex multi-talker auditory scenes in the auditory cortex. Early responses (<85 ms) in primary-like areas appear to represent the individual talkers with almost equal fidelity and are independent of attention in normal-hearing (NH) listeners. However, late responses (>85 ms) in higher-order non-primary areas selectively represent the attended talker with significantly higher fidelity than unattended talkers in NH and hearing-impaired (HI) listeners. Motivated by these findings, the objective of this study was to investigate the effect of a noise reduction scheme (NR) in a commercial hearing aid (HA) on the representation of complex multi-talker auditory scenes in distinct hierarchical stages of the auditory cortex by using high-density electroencephalography (EEG). Design We addressed this issue by investigating early (<85 ms) and late (>85 ms) EEG responses recorded in 34 HI subjects fitted with HAs. The HA noise reduction (NR) was either on or off while the participants listened to a complex auditory scene. Participants were instructed to attend to one of two simultaneous talkers in the foreground while multi-talker babble noise played in the background (+3 dB SNR). After each trial, a two-choice question about the content of the attended speech was presented. Results Using a stimulus reconstruction approach, our results suggest that the attention-related enhancement of neural representations of target and masker talkers located in the foreground, as well as suppression of the background noise in distinct hierarchical stages is significantly affected by the NR scheme. We found that the NR scheme contributed to the enhancement of the foreground and of the entire acoustic scene in the early responses, and that this enhancement was driven by better representation of the target speech. We found that the target talker in HI listeners was selectively represented in late responses. We found that use of the NR scheme resulted in enhanced representations of the target and masker speech in the foreground and a suppressed representation of the noise in the background in late responses. We found a significant effect of EEG time window on the strengths of the cortical representation of the target and masker. Conclusion Together, our analyses of the early and late responses obtained from HI listeners support the existing view of hierarchical processing in the auditory cortex. Our findings demonstrate the benefits of a NR scheme on the representation of complex multi-talker auditory scenes in different areas of the auditory cortex in HI listeners.

    Preparticipation injury complaint is a risk factor for injury: a prospective study of the Moscow 2013 IAAF Championships.2015Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 49, nr 17, s. 1118-U45Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: To determine the health status of athletes before the start of an international athletics championship and to determine whether preparticipation risk factors predicted in-championship injuries.

    METHODS: At the beginning of the 2013 International Association of Athletics Federations (IAAF) World Championships, all registered athletes (n=1784) were invited to complete a preparticipation health questionnaire (PHQ) on health status during the month preceding the championships. New injuries that occurred at the championships were prospectively recorded.

    RESULTS: The PHQ was completed by 698 (39%) athletes; 204 (29.2%) reported an injury complaint during the month before the championships. The most common mode of onset of preparticipation injury complaints was gradual (43.6%). Forty-nine athletes in the study reported at least one injury during the championships. Athletes who reported a preparticipation injury complaint were at twofold increased risk for an in-championship injury (OR=2.09; 95% CI 1.16 to 3.77); p=0.014). Those who reported a preparticipation gradual-onset injury complaint were at an almost fourfold increased risk for an in-championship time-loss injury (OR=3.92; 95% CI 1.69 to 9.08); p=0.001). Importantly, the preparticipation injury complaint severity score was associated with the risk of sustaining an in-championship injury (OR=1.14; 95% CI 1.06 to 1.22); p=0.001).

    SUMMARY AND CONCLUSIONS: About one-third of the athletes participating in the study reported an injury complaint during the month before the championships, which represented a risk factor for sustaining an injury during the championship. This study emphasises the importance of the PHQ as a screening tool to identify athletes at risk of injuries before international championships.

    Cognitive correlates of visual speech understanding in hearing impaired individuals2001Ingår i: Journal of Deaf Studies and Deaf Education, ISSN 1081-4159, Vol. 6, nr 2, s. 103-116Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study examined the extent to which different measures ofspeechreading performance correlated with particular cognitiveabilities in a population of hearing-impaired people. Althoughthe three speechreading tasks (isolated word identification,sentence comprehension, and text tracking) were highly intercorrelated,they tapped different cognitive skills. In this population,younger participants were better speechreaders, and, when agewas taken into account, speech tracking correlated primarilywith (written) lexical decision speed. In contrast, speechreadingfor sentence comprehension correlated most strongly with performanceon a phonological processing task (written pseudohomophone detection)but also on a span measure that may have utilized visual, nonverbalmemory for letters. We discuss the implications of this pattern.

    Dealing with Digits: Arithmetic, Memory and Phonology in Deaf Signers2014Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Dövhet har kopplats till bristande förmåga att hantera siffror inom områdena aritmetik och minne. Särskilt har språkmodalitetsspecifika skillnader i fonologisk likhet för siffror visat sig påverka korttidsminnet. Det övergripande syftet med den här avhandlingen var därför att undersöka om språkmodalitetsspecifika skillnader i fonologisk bearbetning mellan teckenoch talspråk kan förklara varför döva presterar sämre än hörande på sifferuppgifter. För att utforska det området undersöktes fonologisk bearbetning i sifferbaserade minnesuppgifter och aritmetik med hjälp av både beteendevetenskapliga metoder och hjärnavbildning hos grupper av teckenspråkiga döva och talspråkiga hörande som matchats noggrant på ålder, kön, utbildning och icke-verbal intelligens. För att testförhållandena skulle bli så likartade som möjligt för de båda grupperna, och för att förebygga materialeffekter, användes samma presentations- och svarssätt för båda grupperna. Resultaten visade att vid sifferbaserat korttidsminne påverkas de dövas prestation av de tecknade siffrornas fonologiska likhet. Däremot fanns det ingen skillnad mellan grupperna gällande sifferbaserat arbetsminne, vilket kan bero på att de båda grupperna fördelar sina kognitiva resurser på olika sätt. Dessutom fann vi att den grupp teckenspråkiga döva som deltog i studien presterade bättre på aritmetik än vad tidigare forskning visat och de skiljde sig bara från hörande på multiplikationsuppgifter, vilket kan bero på att grupperna var så noggrant matchade. Däremot fanns det skillnader mellan grupperna i vilka neurobiologiska nätverk som aktiverades vid aritmetik och fonologi. Vid multiplikationsuppgifter aktiverades cortex i höger parietallob och vänster frontallob för de teckenspråkiga döva, medan cortex i vänster frontal- och parietallob aktiverades för de talspråkiga hörande. Detta indikerar att de talspråkiga hörande förlitar sig på fonologiberoende minnesstrategier medan de teckenspråkiga döva förlitar sig på ickeverbal magnitudmanipulering och artikulatoriska processer. Under den fonologiska uppgiften aktiverade de talspråkiga hörande vänsterlateraliserade frontala och parietala områden inom det klassiska språknätverket. För de teckenspråkiga döva var fonologibearbetningen begränsad till cortex i vänster occipitallob, vilket tyder på att teckenspråksbaserad fonologi inte behöver aktivera det klassiska språknätverket.

    Abstract [en]

    Similar working memory (WM) for lexical items has been demonstrated for signers and non-signers while short-term memory (STM) is regularly poorer in deaf than hearing individuals. In the present study, we investigated digit-based WM and STM in Swedish and British deaf signers and hearing non-signers. To maintain good experimental control we used printed stimuli throughout and held response mode constant across groups. We showed that deaf signers have similar digit-based WM performance, despite shorter digit spans, compared to well-matched hearing non-signers. We found no difference between signers and non-signers on STM span for letters chosen to minimize phonological similarity or in the effects of recall direction. This set of findings indicates that similar WM for signers and non-signers can be generalized from lexical items to digits and suggests that poorer STM in deaf signers compared to hearing non-signers may be due to differences in phonological similarity across the language modalities of sign and speech.

    Abstract [en]

    Deaf students generally lag several years behind hearing peers in arithmetic, but little is known about the mechanisms behind this. In the present study we investigated how phonological skills interact with arithmetic. Eighteen deaf signers and eighteen hearing non-signers took part in an experiment that manipulated arithmetic and phonological knowledge in the language modalities of sign and speech. Independent tests of alphabetical and native language phonological skills were also administered. There was no difference in performance between groups on subtraction, but hearing non-signers performed better than deaf signers on multiplication. For the deaf signers but not the hearing non-signers, multiplicative reasoning was associated with both alphabetical and phonological skills. This indicates that deaf signing adults rely on language processes to solve multiplication tasks, possibly because automatization of multiplication is less well established in deaf adults.

    Abstract [en]

    Arithmetic and language processing involve similar neural networks, but the relative engagement remains unclear. In the present study we used fMRI to compare activation for phonological, multiplication and subtraction tasks, keeping the stimulus material constant, within a predefined language-calculation network including left inferior frontal gyrus and angular gyrus (AG) as well as superior parietal lobule and the intraparietal sulcus bilaterally. Results revealed a generally left lateralized activation pattern within the language-calculation network for phonology and a bilateral activation pattern for arithmetic, and suggested regional differences between tasks. In particular, we found a more prominent role for phonology than arithmetic in pars opercularis of the left inferior frontal gyrus but domain generality in pars triangularis. Parietal activation patterns demonstrated greater engagement of the visual and quantity systems for calculation than language. This set of findings supports the notion of a common, but regionally differentiated, language-calculation network. (C) 2015 The Authors. Published by Elsevier Inc.

    Abstract [en]

    Evidence suggests that the lag reported in mathematics for deaf signers derives from difficulties related to the verbal system of number processing as described in the triple code model. For hearing individuals the verbal system has been shown to be recruited for both arithmetic and language tasks. In the present study we investigate for the first time neuronal representations of arithmetic in deaf signers. We examine if the neural network supporting arithmetic and language, including the horizontal portion of the intraparietal sulcus (HIPS), the superior parietal lobule (SPL) bilaterally, the left angular gyrus (AG), pars opercularis (POPE) and pars triangularis (PTRI) of the left inferior frontal gyrus (IFG), is differently recruited for deaf and hearing individuals. Imaging data were collected from 16 deaf signers and 16 well-matched hearing nonsigners, using the same stimulus material for all tasks, but with different cues. During multiplication, deaf signers recruited rHIPS more than hearing non-signers, suggesting greater involvement of magnitude manipulation processes related to the quantity system, whereas there was no evidence that the verbal system was recruited. Further, there was no support for the notion of a common representation of phonology for sign and speech as previously suggested.

    Greater reliance on magnitude manipulation during mental arithmetic in deaf signers compared to hearing non-signers: fMRI evidence2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Evidence suggests that the lag reported in mathematics for deaf signers derives from difficulties related to verbal processing of numbers, whereas magnitude processing seems unaffected by deafness. Neuroimaging evidence from hearing individuals suggests that verbal processing of numbers engages primarily left angular gyrus (lAG), whereas magnitude processing engages primarily the horizontal portion of the right intraparietal sulcus (rHIP). In a ROI analysis of brain imaging data from 16 adult deaf signers and 16 adult hearing non-signers, who did not differ on sex, age or education, we examined if activity in lAG and rHIP changed as a result of task (multiplication vs subtraction) and group (deaf signers and hearing non-signers). We found a significant main effect of brain region (F(1,30) = 117.00, p < .001, η_p^2 = .80) and an interaction effect between region and group (F(1,30) = 20.70, p < .001, η_p^2 = .41). Further analyses showed that there were no significant differences in average activation between groups in lAG (F(1,30) = 0.16, p = .70). However, in rHIP deaf signers showed significantly greater average activation compared to non-signers (F(1,30) = 15.20, p < .001, η_p^2 = .34). There were no significant differences in activation between subtraction and multiplication (F(1,30) = 0.66, p = .42) and no behavioural differences between groups (F(1,30) = 1.70, p = .20). These results suggest that when engaging in arithmetic tasks deaf signers successfully make use of qualitatively difference processes, compared to hearing non-signers, with stronger emphasis on brain regions relating to magnitude manipulation.

    Arithmetic in the adult deaf signing brain2020Ingår i: Journal of Neuroscience Research, ISSN 0360-4012, E-ISSN 1097-4547, Vol. 98, nr 4, s. 643-654Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We have previously shown that deaf signers recruit partially different brain regions during simple arithmetic compared to a group of hearing non-signers, despite similar performance. Specifically, hearing individuals show more widespread activation in brain areas that have been related to the verbal system of numerical processing, i.e., the left angular and inferior frontal gyrus, whereas deaf individuals engaged brain areas that have been related to the quantity system of numerical processing, i.e., the right horizontal intraparietal sulcus. This indicates that compared to hearing non-signers, deaf signers can successfully make use of processes located in partially different brain areas during simple arithmetic. In this study, which is a conceptual replication and extension of the above-presented study, the main aim is to understand similarities and differences in neural correlates supporting arithmetic in deaf compared to hearing individuals. The primary objective is to investigate the role of the right horizontal intraparietal gyrus, the left inferior frontal gyrus, the hippocampus, and the left angular gyrus during simple and difficult arithmetic and how these regions are connected to each other. A second objective is to explore what other brain regions support arithmetic in deaf signers. Up to 34 adult deaf signers and the same amount of hearing non-signers will be enrolled in an functional magnetic resonance imaging study that will include simple and difficult subtraction and multiplication. Brain imaging data will be analyzed using whole-brain analysis, region of interest analysis and connectivity analysis. This is the first study to investigate neural underpinnings of arithmetic of different difficulties in deaf individuals.

    Deaf signers and hearing non-signers recruit similar networks for arithmetic and phonological tasks2013Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Profoundly deaf individuals sometimes have difficulty with arithmetic and phonological tasks. In the present study we investigate if these differences can be attributed to differences in recruitment of neurobiological networks. Seventeen hearing non-signers (HN) and sixteen deaf signers (DS) matched on age, gender and non-verbal intelligence took part in an fMRI study. In the scanner three digit/letter pairs were visually presented and the participants performed six different blocked tasks tapping processing of digit and letter order, multiplication, subtraction and phonological ability. Data were analysed using two 2x2x2 ANOVAs; process (arithmetic, language) x level (high, low) x group (DS, HN). A main effect of process revealed language networks in the left inferior frontal gryus, supramarginal gyrus, fusiform gyrus and insula. Arithmetic networks included left middle orbital gyrus and superior medial gyrus. A main effect of level revealed low level processing (digit/letter order) in the right middle occipital gyrus and the right precuneus and high level processing (subtraction/multiplication/phonological ability) in left inferior frontal gyrus. There was no main effect of group but a significant task x group interaction in the right temporal pole which in DS (but not HN) was activated more for arithmetic than language processing (pfwe = .022) when multiplication was included in the analysis. This region is implicated in conceptual representation. These results suggest that both arithmetic and language are processed similarly by DS and HN with possible between-group differences in the use of conceptual representation in arithmetic and language tasks.

    Multiplication engages phonological networks in Broca's area differently for deaf signers and hearing non-signers2012Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    In hearing individuals, multiplication relies mainly on the phonological loop while subtraction relies on the visuo-spatial sketchpad (VSSP; Lee & Kang, 2002). Little is known about arithmetic neural networks in deaf signers (DS). Since DS often perform worse than hearing non-signers (NH) on arithmetic in general and multiplication in particular (Traxler, 2000), we hypothesized that there are strategic differences between how groups recruit the phonological loop in multiplication, but not in subtraction, leading to differential activation of phonological processing areas in left inferior frontal gyrus (Broca’s area). We investigated this using a blocked fMRI-design in which nine DS and 17 HN matched on age, gender, education and non-verbal intelligence (Raven & Raven, 1998) were tested on tasks of multiplication, subtraction and phonology (rhyme). The contrasts rhyme versus multiplication and rhyme versus subtraction were examined across groups within the region of interest defined by a probability map of Broca’s area (Amunts, 1999). We observed a significant interaction between task (multiplication and rhyme) and group (F = 12.64, p = .034, FWE-corrected), where the HN showed higher activation for rhyme than for multiplication (T = 4.55, p = .001, FWE-corrected) whereas there were no differences in activations between tasks for DS. For subtraction versus rhyme no interaction with group was found. These results suggest that there are differences between DS and HN in the phonology dependent neural networks in Broca’s area used during multiplication, which may be part of the explanation for poorer performance in DS.

    The neural basis of arithmetic and phonology in deaf signing individuals2019Ingår i: Language, Cognition and Neuroscience, ISSN 2327-3798, E-ISSN 2327-3801, Vol. 34, nr 7, s. 813-825Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Deafness is generally associated with poor mental arithmetic, possibly due to neuronal differences in arithmetic processing across language modalities. Here, we investigated for the first time the neuronal networks supporting arithmetic processing in adult deaf signers. Deaf signing adults and hearing non-signing peers performed arithmetic and phonological tasks during fMRI scanning. At whole brain level, activation patterns were similar across groups. Region of interest analyses showed that although both groups activated phonological processing regions in the left inferior frontal gyrus to a similar extent during both phonological and multiplication tasks, deaf signers showed significantly more activation in the right horizontal portion of the inferior parietal sulcus. This region is associated with magnitude manipulation along the mental number line. This pattern of results suggests that deaf signers rely more on magnitude manipulation than hearing non-signers during multiplication, but that phonological involvement does not differ significantly between groups.Abbreviations: AAL: Automated Anatomy Labelling; fMRI: functional magnetic resonance imaging; HIPS: horizontal portion of the intraparietal sulcus; lAG: left angular gyrus; lIFG: left inferior frontal gyrus; rHIPS: right horizontal portion of the intraparietal sulcus

    fMRI Evidence of Magnitude Manipulation during Numerical Order Processing in Congenitally Deaf Signers2018Ingår i: Neural Plasticity, ISSN 2090-5904, E-ISSN 1687-5443, artikel-id 2576047Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Congenital deafness is often compensated by early sign language use leading to typical language development with corresponding neural underpinnings. However, deaf individuals are frequently reported to have poorer numerical abilities than hearing individuals and it is not known whether the underlying neuronal networks differ between groups. In the present study, adult deaf signers and hearing nonsigners performed a digit and letter order tasks, during functional magnetic resonance imaging. We found the neuronal networks recruited in the two tasks to be generally similar across groups, with significant activation in the dorsal visual stream for the letter order task, suggesting letter identification and position encoding. For the digit order task, no significant activation was found for either of the two groups. Region of interest analyses on parietal numerical processing regions revealed different patterns of activation across groups. Importantly, deaf signers showed significant activation in the right horizontal portion of the intraparietal sulcus for the digit order task, suggesting engagement of magnitude manipulation during numerical order processing in this group.

    Phonology and arithmetic in the language-calculation network2015Ingår i: Brain and Language, ISSN 0093-934X, E-ISSN 1090-2155, Vol. 143, s. 97-105Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Arithmetic and language processing involve similar neural networks, but the relative engagement remains unclear. In the present study we used fMRI to compare activation for phonological, multiplication and subtraction tasks, keeping the stimulus material constant, within a predefined language-calculation network including left inferior frontal gyrus and angular gyrus (AG) as well as superior parietal lobule and the intraparietal sulcus bilaterally. Results revealed a generally left lateralized activation pattern within the language-calculation network for phonology and a bilateral activation pattern for arithmetic, and suggested regional differences between tasks. In particular, we found a more prominent role for phonology than arithmetic in pars opercularis of the left inferior frontal gyrus but domain generality in pars triangularis. Parietal activation patterns demonstrated greater engagement of the visual and quantity systems for calculation than language. This set of findings supports the notion of a common, but regionally differentiated, language-calculation network. (C) 2015 The Authors. Published by Elsevier Inc.

    Reorganization of large-scale brain networks in deaf signing adults: The role of auditory cortex in functional reorganization following deafness2022Ingår i: Neuropsychologia, ISSN 0028-3932, E-ISSN 1873-3514, Vol. 166, artikel-id 108139Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    If the brain is deprived of input from one or more senses during development, functional and structural reorganization of the deprived regions takes place. However, little is known about how sensory deprivation affects large-scale brain networks. In the present study, we use data-driven independent component analysis (ICA) to characterize large-scale brain networks in 15 deaf early signers and 24 hearing non-signers based on resting-state functional MRI data. We found differences between the groups in independent components representing the left lateralized control network, the default network, the ventral somatomotor network, and the attention network. In addition, we showed stronger functional connectivity for deaf compared to hearing individuals from the middle and superior temporal cortices to the cingulate cortex, insular cortex, cuneus and precuneus, supramarginal gyrus, supplementary motor area, and cerebellum crus 1, and stronger connectivity for hearing non-signers to hippocampus, middle and superior frontal gyri, pre- and postcentral gyri, and cerebellum crus 8. These results show that deafness induces large-scale network reorganization, with the middle/superior temporal cortex as a central node of plasticity. Cross-modal reorganization may be associated with behavioral adaptations to the environment, including superior ability in some visual functions such as visual working memory and visual attention, in deaf signers.

    Working Memory for Signs with Poor Visual Resolution: fMRI Evidence of Reorganizationof Auditory Cortex in Deaf Signers2021Ingår i: Cerebral Cortex, ISSN 1047-3211, E-ISSN 1460-2199, Vol. 31, nr 7, s. 3165-3176Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Stimulus degradation adds to working memory load during speech processing.We investigated whether this applies to signprocessing and, if so, whether the mechanism implicates secondary auditory cortex.We conducted an fMRI experimentwhere 16 deaf early signers (DES) and 22 hearing non-signers performed a sign-based n-back task with three load levels andstimuli presented at high and low resolution.We found decreased behavioral performance with increasing load anddecreasing visual resolution, but the neurobiological mechanisms involved differed between the two manipulations and didso for both groups. Importantly, while the load manipulation was, as predicted, accompanied by activation in thefrontoparietal working memory network, the resolution manipulation resulted in temporal and occipital activation.Furthermore, we found evidence of cross-modal reorganization in the secondary auditory cortex: DES had strongeractivation and stronger connectivity between this and several other regions.We conclude that load and stimulus resolutionhave different neural underpinnings in the visual–verbal domain, which has consequences for current working memorymodels, and that for DES the secondary auditory cortex is involved in the binding of representations when task demandsare low.

    Similar digit-based working memory in deaf signers and hearing non-signers despite digit span differences2013Ingår i: Frontiers in Psychology, E-ISSN 1664-1078, Vol. 4, nr 942Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Similar working memory (WM) for lexical items has been demonstrated for signers and non-signers while short-term memory (STM) is regularly poorer in deaf than hearing individuals. In the present study, we investigated digit-based WM and STM in Swedish and British deaf signers and hearing non-signers. To maintain good experimental control we used printed stimuli throughout and held response mode constant across groups. We showed that deaf signers have similar digit-based WM performance, despite shorter digit spans, compared to well-matched hearing non-signers. We found no difference between signers and non-signers on STM span for letters chosen to minimize phonological similarity or in the effects of recall direction. This set of findings indicates that similar WM for signers and non-signers can be generalized from lexical items to digits and suggests that poorer STM in deaf signers compared to hearing non-signers may be due to differences in phonological similarity across the language modalities of sign and speech.

    Deaf signers use phonology to do arithmetic2014Ingår i: Learning and individual differences, ISSN 1041-6080, E-ISSN 1873-3425, Vol. 32, s. 246-253Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Deaf students generally lag several years behind hearing peers in arithmetic, but little is known about the mechanisms behind this. In the present study we investigated how phonological skills interact with arithmetic. Eighteen deaf signers and eighteen hearing non-signers took part in an experiment that manipulated arithmetic and phonological knowledge in the language modalities of sign and speech. Independent tests of alphabetical and native language phonological skills were also administered. There was no difference in performance between groups on subtraction, but hearing non-signers performed better than deaf signers on multiplication. For the deaf signers but not the hearing non-signers, multiplicative reasoning was associated with both alphabetical and phonological skills. This indicates that deaf signing adults rely on language processes to solve multiplication tasks, possibly because automatization of multiplication is less well established in deaf adults.

    Abstract [en]

    Cognitive impairment may cause difficulties in planning and initiating daily activities, as well as remembering to do what is scheduled. This study investigates the effectiveness of an interactive web-based mobile reminder calendar that sends text messages to the users mobile phone as support in everyday life, for persons with cognitive impairment due to neurological injury/diagnoses. The study has a randomised controlled trail design with data collection at baseline and at follow-up sessions after two and four months. Data collection started in August 2016 and continues until December 2017. The interactive web-based mobile reminder calendar may give the needed support to remind the person and thus increase the ability to perform activities and to be independence in everyday life. Preliminary results will be presented regarding what effect the interactive web-based mobile reminder calendar have for the participants performance of everyday life activities as well as perceived quality of life.

    An interactive digital calendar with mobile phone reminders (RemindMe) for people with cognitive impairment: a pilot randomized controlled trial2022Ingår i: Scandinavian Journal of Occupational Therapy, ISSN 1103-8128, E-ISSN 1651-2014, Vol. 29, nr 4, s. 270-281Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background People with cognitive impairment often need support to perform everyday-life activities. Interventions are available, but evidence-based interventions are lacking. Aim This pilot RCT aimed to investigate use of an intervention with an interactive digital calendar with mobile phone reminders (RemindMe) in relation to change in outcomes and impact on occupational performance, independence, health-related quality of life, and psychosocial impact of the support for people with cognitive impairment. Method The study design was a multi-centre parallel-group pilot RCT [ClinicalTrails.gov, identifier: NCT04470219]. Fifteen participants from primary rehabilitation centres in Sweden were recruited and randomly assigned to intervention group (n = 8) receiving the intervention with RemindMe, or control group (n = 7) receiving usual treatment by an occupational therapist. Data were collected at baseline, after two- and four months, and analysed using descriptive and non-parametric statistics. Result The Canadian Occupational Performance Measure (COPM), and the Functional Independence Measure (FIM item n-r) showed significant differences. There were no significant differences in health-related quality of life nor in the psychosocial impact of the used support. Conclusion Plausible changes in outcome measures were found in COPM and FIM (items n-r). These instruments indicate change in outcome measures and impact on occupational performance and independence.

    Feasibility of an Intervention for Patients with Cognitive Impairment Using an Interactive Digital Calendar with Mobile Phone Reminders (RemindMe) to Improve the Performance of Activities in Everyday Life2020Ingår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, nr 7, artikel-id 2222Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study is to increase evidence-based interventions by investigating the feasibility of an intervention using an interactive digital calendar with mobile phone reminders (RemindMe) as support in everyday life. Qualitative and quantitative data were collected from participating patients (n = 8) and occupational therapists (n = 7) from three rehabilitation clinics in Sweden. The intervention consisted of delivering the interactive digital calendar RemindMe, receiving an individualized introduction, a written manual, and individual weekly conversations for two months with follow-up assessments after two and four months. Feasibility areas of acceptability, demand, implementation, practicality, and integration were examined. Patients expressed their interest and intention to use RemindMe and reported a need for reminders and individualized support. By using reminders in activities in everyday life their autonomy was supported. The study also demonstrated the importance of confirming reminders and the possible role of habit-forming. Occupational therapists perceived the intervention to be useful at the rehabilitation clinics and the weekly support conversations enabled successful implementation. This study confirmed the importance of basing and tailoring the intervention to patients needs and thus being person-centered.

    Child physical abuse: factors influencing the associations between self-reported exposure and self-reported health problems: a cross-sectional study2018Ingår i: Child and Adolescent Psychiatry and Mental Health, E-ISSN 1753-2000, Vol. 12, artikel-id 38Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Child physical abuse (CPA) is an extensive public health problem because of its associations with poor health outcomes. The aim of this study was to examine which of the background factors of CPA committed by a parent or other caregiver relates to self-reported poor health among girls and boys (13; 15 and 17 years old): perpetrator, last year exposure; severity and frequency; socioeconomic load and foreign background.

    Methods

    In a cross-sectional study in a Swedish county (n = 8024) a path analysis was performed to evaluate a model where all background variables were put as predictors of three health-status variables: mental; physical and general health problems. In a second step a log linear analysis was performed to examine how the distribution over the health-status categories was different for different combinations of background factors.

    Results

    Children exposed to CPA reported poor health to a much higher extent than those who were not exposed. In the path analysis it was found that frequency and severity of abuse (boys only) and having experienced CPA during the last year, was significantly associated with poor health as well as socioeconomic load in the families. Foreign background was significantly negatively associated with all three health indicators especially for girls. Neither mother nor father as perpetrator remained significant in the path analysis, while the results from the log linear analyses showed that mother-abuse did in fact relate to poor general health and mental as well as physical health problems among boys and girls. Father-abuse was associated with poor mental health if severe abuse was reported. Poor mental health was also associated with mild father-abuse if exposure during the last year was reported.

    Conclusion

    Despite the limitations that cross-sectional studies imply, this study provides new knowledge about factors associated with poor health among physically abused children. It describes details of CPA that have significant associations to different aspects of poor health and thus what needs to be addressed by professionals within mental health providers and social services. Understanding how different factors may contribute to different health outcomes for exposed children is important in future research and needs further studies.

    Relationship Among Signal Fidelity, Hearing Loss, and Working Memory for Digital Noise Suppression2015Ingår i: Ear and Hearing, ISSN 0196-0202, E-ISSN 1538-4667, Vol. 36, nr 5, s. 505-516Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: This study considered speech modified by additive babble combined with noise-suppression processing. The purpose was to determine the relative importance of the signal modifications, individual peripheral hearing loss, and individual cognitive capacity on speech intelligibility and speech quality. Design: The participant group consisted of 31 individuals with moderate high-frequency hearing loss ranging in age from 51 to 89 years (mean = 69.6 years). Speech intelligibility and speech quality were measured using low-context sentences presented in babble at several signal-to-noise ratios. Speech stimuli were processed with a binary mask noise-suppression strategy with systematic manipulations of two parameters (error rate and attenuation values). The cumulative effects of signal modification produced by babble and signal processing were quantified using an envelope-distortion metric. Working memory capacity was assessed with a reading span test. Analysis of variance was used to determine the effects of signal processing parameters on perceptual scores. Hierarchical linear modeling was used to determine the role of degree of hearing loss and working memory capacity in individual listener response to the processed noisy speech. The model also considered improvements in envelope fidelity caused by the binary mask and the degradations to envelope caused by error and noise. Results: The participants showed significant benefits in terms of intelligibility scores and quality ratings for noisy speech processed by the ideal binary mask noise-suppression strategy. This benefit was observed across a range of signal-to-noise ratios and persisted when up to a 30% error rate was introduced into the processing. Average intelligibility scores and average quality ratings were well predicted by an objective metric of envelope fidelity. Degree of hearing loss and working memory capacity were significant factors in explaining individual listeners intelligibility scores for binary mask processing applied to speech in babble. Degree of hearing loss and working memory capacity did not predict listeners quality ratings. Conclusions: The results indicate that envelope fidelity is a primary factor in determining the combined effects of noise and binary mask processing for intelligibility and quality of speech presented in babble noise. Degree of hearing loss and working memory capacity are significant factors in explaining variability in listeners speech intelligibility scores but not in quality ratings.

    Relationship between distortion and working memory for digital noise-reduction processing in hearing aids2014Ingår i: Journal of the Acoustical Society of America, ISSN 0001-4966, Vol. 133, nr 5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Several recent studies have shown a relationship between working memory and the ability of older adults to benefit from specific advanced signal processing algorithms in hearing aids. In this study, we quantify tradeoffs between benefit due to noise reduction and the perceptual costs associated with distortion caused by the noise reduction algorithm. We also investigate the relationship between these tradeoffs and working memory abilities. Speech intelligibility, speech quality, and perceived listening effort were measured in a cohort of elderly adults with hearing loss. Test materials were low-context sentences presented in fluctuating noise conditions at several signal-to-noise ratios. Speech stimuli were processed with a binary mask noise-reduction strategy. The amount of distortion produced by the noise reduction algorithm was parametrically varied by manipulating two binary mask parameters, error rate, and attenuation rate. Working memory was assessed with a reading span test. Results will be discussed in terms of the extent to which intelligibility, quality, and effort ratings are explained by the amount of distortion and/or noise and by working memory ability.

    An exploratory study identifying a possible response shift phenmena of the Glassglow hearing aid benifit profile2016Ingår i: Audiology Research, ISSN 2039-4330, E-ISSN 2039-4349, Vol. 6, nr 2, s. 44-48Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A then test technique was used to investigate the possibility of a response shift in the Glasgow hearing aid benefit profile (GHABP). Following completion of part 1 of the GHABP, 16 adults were invited for hearing-aid follow up appointments. In accordance with then-test technique, participants were asked to think back to before they had their hearing-aids fitted and the GHABP part 1 was completed again to re-establish the disability and handicap scores. These scores were then compared with the initial GHABP part I scores. Paired T testing and Wilcoxon Rank tests were carried out to investigate the statistical significance of the response shift effect. Statistically significant differences were seen between initial and retrospective GHABP (disability) scores using t test. No significant differences could be seen between the initial and retrospective handicap scores. Results suggest participants may have demonstrated a possible response shift phenomenon with the disability construct of the GHABP questionnaire, related to a possible re-calibration effect or a denial of disability effect. This exploratory study suggests that the GHABP questionnaire may be subject to a response shift phenomena. We suggest that further more robust studies are completed to verify this and recommend that this could have psychological impact on participants when explaining the results of the outcome measure and may affect hearing aid use. There is also potential for this phenomenon to affect global GHABP scores specifically when demonstrating to stakeholders the overall success of an audiology service.

    The Relationship between Reading Comphehension, Working Memory and Language in Children with Cochlear Implants2007Ingår i: Acta Neuropsychologica, ISSN 1730-7503, Vol. 5, nr 4, s. 163-186Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    and profound hearing impairment treated by cochlear implants (CI). In this study we explore this relationship in sixteen Swedish children with CI. We found that over 60% of the children with CI performed at the level of their hearing peers in a reading comprehension test. Demographic factors were not predictive of reading comprehension, but a complex working memory task was. Reading percentile was significantly correlated to the working memory test, but no other correlations between reading and cognitive/linguistic factors remained significant after age was factored out. Individual results from a comparison of the two best and the two poorest readers corroborate group results, confirming the important role of working memory for reading as measured by comprehension of words and sentences in this group of children.

    Quality and readability of English-language internet information for aphasia2019Ingår i: International Journal of Speech-Language Pathology, ISSN 1754-9507, E-ISSN 1754-9515, Vol. 21, nr 1Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: Little is known about the quality and readability of treatment information in specific neurogenic disorders, such as aphasia. The purpose of this study was to assess quality and readability of English-language Internet information available for aphasia treatment. Method: Forty-three aphasia treatment websites were aggregated using five different country-specific search engines. Websites were then analysed using quality and readability assessments. Statistical calculations were employed to examine website ratings, differences between website origin and quality and readability scores, and correlations between readability instruments. Result: Websites exhibited low quality with few websites obtaining Health On the Net (HON) certification or clear, thorough information as measured by the DISCERN. Regardless of website origin, readability scores were also poor. Approximate educational levels required to comprehend information on aphasia treatment websites ranged from 13 to 16 years of education. Significant differences were found between website origin and readability measures with higher levels of education required to understand information on websites of non-profit organisations. Conclusion: Current aphasia treatment websites were found to exhibit low levels of quality and readability, creating potential accessibility problems for people with aphasia and significant others. Websites including treatment information for aphasia must be improved in order to increase greater information accessibility.
