    New measures of masked text recognition in relation to speech-in-noise perception and their associations with age and cognitive abilities2012Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 55, nr 1, s. 194-209Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: This research aimed to increase the analogy between text reception threshold (TRT) and speech reception threshold (SRT) and to examine the TRT's value in estimating cognitive abilities important for speech comprehension in noise.

    Method: We administered five TRT versions, SRT tests in stationary (SRTSTAT) and modulated (SRTMOD) noise, and two cognitive tests: a reading span (RSpan) test for working memory capacity, and a letter-digit-substitution test for information processing speed. Fifty-five normal hearing adults (18–78 years, mean = 44) participated. We examined mutual associations of the tests and their predictive value for the SRTs with correlation and linear regression analyses.

    Results: SRTs and TRTs were well associated, also when controlling for age. Correlations for the SRTSTAT were generally lower than for the SRTMOD. The cognitive tests were only correlated to the SRTs when age was not controlled for. Age and the TRTs were the only significant predictors of SRTMOD. SRTSTATwas predicted by level of education and some of the TRT versions.

    Conclusions: TRTs and SRTs are robustly associated, nearly independent of age. The association between SRTs and RSpan is largely age-dependent. The TRT test and the RSpan test measure different non-auditory components of linguistic processing relevant for speech perception in noise.

    Effects on vocal fold collision and phonation threshold pressure of resonance tube phonation with tube end in water2013Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 56, s. 1530-1538Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: Resonance tube phonation in water (RTPW) or in air is a voice therapy method successfully used for treatment of several voice pathologies. Its effect on the voice has not been thoroughly studied. This investigation analyzes the effects of RTPW on collision and phonation threshold pressures (CTP and PTP), the lowest subglottal pressure needed for vocal fold collision and phonation, respectively.

    Method: Twelve mezzo-sopranos phonated into a glass tube, the end of which was placed under the water surface in a jar. Subglottal pressure, electroglottography and audio signals were recorded before and after exercise. Also, the perceptual effects were assessed in a listening test with an expert panel which also rated the subjects’ singing experience.

    Results: Resonance tube phonation significantly increased CTP, and also tended to improve perceived voice quality. The latter effect was mostly greater in singers who did not practice singing daily. In addition, a more pronounced perceptual effect was found in singers rated as being less experienced.

    Conclusion: Resonance tube phonation significantly raised CTP and tended to improve perceptual ratings of voice quality. The effect on PTP failed to reach significance.

    Effects of Second Language Proficiency and Linguistic Uncertainty on Recognition of Speech in Native and Nonnative Competing Speech2018Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 61, nr 7, s. 1815-1830Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose The purpose of this study was to investigate the effects of 2nd language proficiency and linguistic uncertainty on performance and listening effort in mixed language contexts.

    Method Thirteen native speakers of Dutch with varying degrees of fluency in English listened to and repeated sentences produced in both Dutch and English and presented in the presence of single-talker competing speech in both Dutch and English. Target and masker language combinations were presented in both blocked and mixed (unpredictable) conditions. In the blocked condition, in each block of trials the target–masker language combination remained constant, and the listeners were informed of both prior to beginning the block. In the mixed condition, target and masker language varied randomly from trial to trial. All listeners participated in all conditions. Performance was assessed in terms of speech reception thresholds, whereas listening effort was quantified in terms of pupil dilation.

    Results Performance (speech reception thresholds) and listening effort (pupil dilation) were both affected by 2nd language proficiency (English test score) and target and masker language: Performance was better in blocked as compared to mixed conditions, with Dutch as compared to English targets, and with English as compared to Dutch maskers. English proficiency was correlated with listening performance. Listeners also exhibited greater peak pupil dilation in mixed as compared to blocked conditions for trials with Dutch maskers, whereas pupil dilation during preparation for speaking was higher for English targets as compared to Dutch ones in almost all conditions.

    Conclusions Both listener's proficiency in a 2nd language and uncertainty about the target language on a given trial play a significant role in how bilingual listeners attend to speech in the presence of competing speech in different languages, but precise effects also depend on which language is serving as target and which as masker.

    Parents Perception of Health-Related Quality of Life in Children With Cochlear Implants: The Impact of Language Skills and Hearing2018Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 61, nr 8Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: The study compared how parents of children with cochlear implants (CIs) and parents of children with normal hearing perceive their childrens health-related quality of life (HR-QOL). Method: The sample consisted of 186 Norwegian-speaking children in the age span of 5; 0-12; 11 (years; months): 106 children with CIs (53% boys, 47% girls) and 80 children with normal hearing (44% boys, 56% girls). No children had known additional disabilities affecting language, cognitive development, or HR-QOL. Parents completed the generic questionnaire Pediatric Quality of Life Inventory (Varni, Seid, amp; Kurtin, 2001), whereas children completed a test battery measuring different aspects of language and hearing. Results: Parents of children with CIs reported statistically significantly poorer HR-QOL in their children, on Pediatric Quality of Life Inventory total score and the subdomains social functioning and school functioning. Roughly 50% of parents of children with CIs reported HR-QOL levels (total score) within normal limits. No significant differences between groups emerged on the physical health and emotional functioning subscales. For the children in the group with CIs, better speech perception in everyday situations was associated with higher proxy-ratings of HR-QOL. Better spoken language skills were weakly to moderately associated with higher HR-QOL. Conclusions: The findings suggest that the social and school situation is not yet resolved satisfactorily for children with CIs. Habilitation focusing on spoken language skills and better sound environment may improve social interactions with peers and overall school functioning.

    Perceived Voice Quality and Voice-Related Problems Among Older Adults With Hearing Impairments2018Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 61, nr 9, s. 2168-2178Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The auditory system helps regulate phonation. A speakers perception of their own voice is likely to be of both emotional and functional significance. Although many investigations have observed deviating voice qualities in individuals who are prelingually deaf or profoundly hearing impaired, less is known regarding how older adults with acquired hearing impairments perceive their own voice and potential voice problems. Purpose: The purpose of this study was to investigate problems relating to phonation and self-perceived voice sound quality in older adults based on hearing ability and the use of hearing aids. Method: This was a cross-sectional study, with 290 participants divided into 3 groups (matched by age and gender): (a) individuals with hearing impairments who did not use hearing aids (n = 110), (b) individuals with hearing impairments who did use hearing aids (n = 110), and (c) individuals with no hearing impairments (n = 70). All participants underwent a pure-tone audiometry exam; completed standardized questionnaires regarding their hearing, voice, and general health; and were recorded speaking in a soundproof room. Results: The hearing aid users surpassed the benchmarks for having a voice disorder on the Voice Handicap Index (VHI; Jacobson et al., 1997) at almost double the rate predicted by the Swedish normative values for their age range, although there was no significant difference in acoustical measures between any of the groups. Both groups with hearing impairments scored significantly higher on the VHI than the control group, indicating more impairment. It remains inconclusive how much hearing loss versus hearing aids separately contribute to the difference in voice problems. The total scores on the Hearing Handicap Inventory for the Elderly (Ventry amp; Weinstein, 1982), in combination with the variables gender and age, explained 21.9% of the variance on the VHI. Perceiving ones own voice as being distorted, dull, or hollow had a strong negative association with a general satisfaction about the sound quality of ones own voice. In addition, groupwise differences in own-voice descriptions suggest that a negative perception of ones voice could be influenced by alterations caused by hearing aid processing. Conclusions: The results indicate that hearing impairments and hearing aids affect several aspects of vocal satisfaction in older adults. A greater understanding of how hearing impairments and hearing aids relate to voice problems may contribute to better voice and hearing care.

    Speech Recognition and Cognitive Skills in Bimodal Cochlear Implant Users2017Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 60, nr 9, s. 2752-2763Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To examine the relation between speech recognition and cognitive skills in bimodal cochlear implant (CI) and hearing aid users.

    Method: Seventeen bimodal CI users (28-74 years) were recruited to the study. Speech recognition tests were carried out in quiet and in noise. The cognitive tests employed included the Reading Span Test and the Trail Making Test (Daneman & Carpenter, 1980; Reitan, 1958, 1992), measuring working memory capacity and processing speed and executive functioning, respectively. Data were analyzed using paired-sample t tests, Pearson correlations, and partial correlations controlling for age.

    Results: The results indicate that performance on some cognitive tests predicts speech recognition and that bimodal listening generates a significant improvement in speech in quiet compared to unilateral CI listening. However, the current results also suggest that bimodal listening requires different cognitive skills than does unimodal CI listening. This is likely to relate to the relative difficulty of having to integrate 2 different signals and then map the integrated signal to representations stored in the long-term memory.

    Conclusions: Even though participants obtained speech recognition benefit from bimodal listening, the results suggest that processing bimodal stimuli involves different cognitive skills than does unimodal conditions in quiet. Thus, clinically, it is important to consider this when assessing treatment outcomes.

    Predictors of Rehabilitation Intervention Decisions in Adults With Acquired Hearing Impairment2011Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 54, s. 1385-1399Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: This study investigated the predictors of rehabilitation intervention decisions in middle-age and older adults with acquired hearing impairment seeking help for the first time.

    Method: Using shared decision making, 139 participants were offered intervention options: hearing aids, communication programs (group or individual), and no intervention. Multivariate analysis (logistic regression) provided odds ratios and 95% confidence intervals for intervention decision predictors when all other variables were held constant.

    Results: Seven intervention decision predictors were identified: (a) application for subsidized hearing services (participants more likely to choose hearing aids and less likely to choose communication programs), (b) hearing impairment (hearing aids more likely and no intervention less likely), (c) communication self-efficacy (hearing aids less likely), (d) powerful others as locus of control (hearing aids less likely), (e) hearing disability perceived by others and self (hearing aids more likely), (f ) perceived communication program effectiveness (communication programs more likely), and (g) perceived suitability of individual communication program (hearing aids less likely and communication programs more likely).

    Conclusion: Findings suggest the need for clinicians to explicitly elicit the predictors identified by this study when involving adults with acquired hearing impairment in intervention decisions.

    Visual phonemic ambiguity and speechreading2006Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 49, nr 4, s. 835-847Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To study the role of visual perception of phonemes in visual perception of sentences and words among normal-hearing individuals. Method: Twenty-four normal-hearing adults identified consonants, words, and sentences, spoken by either a human or a synthetic talker. The synthetic talker was programmed with identical parameters within phoneme groups, hypothetically resulting in simplified articulation. Proportions of correctly identified phonemes per participant, condition, and task, as well as sensitivity to single consonants and clusters of consonants, were measured. Groups of mutually exclusive consonants were used for sensitivity analyses and hierarchical cluster analyses. Results: Consonant identification performance did not differ as a function of talker, nor did average sensitivity to single consonants. The bilabial and labiodental clusters were most readily identified and cohesive for both talkers. Word and sentence identification was better for the human talker than the synthetic talker. The participants were more sensitive to the clusters of the least visible consonants with the human talker than with the synthetic talker. Conclusions: It is suggested that ability to distiguish between clusters of the least visually distinct phonemes is important in speechreading. Specifically, it reduces the number of candidates, and thereby facilitates lexical identification. © American Speech-Language-Hearing Association.

    Visual Information Can Hinder Working Memory Processing of Speech2013Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 56, nr 4, s. 1120-1132Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE:

    The purpose of the present study was to evaluate the new Cognitive Spare Capacity Test (CSCT), which measures aspects of working memory capacity for heard speech in the audiovisual and auditory-only modalities of presentation.

    METHOD:

    In Experiment 1, 20 young adults with normal hearing performed the CSCT and an independent battery of cognitive tests. In the CSCT, they listened to and recalled 2-digit numbers according to instructions inducing executive processing at 2 different memory loads. In Experiment 2, 10 participants performed a less executively demanding free recall task using the same stimuli.

    RESULTS:

    CSCT performance demonstrated an effect of memory load and was associated with independent measures of executive function and inference making but not with general working memory capacity. Audiovisual presentation was associated with lower CSCT scores but higher free recall performance scores.

    CONCLUSIONS:

    CSCT is an executively challenging test of the ability to process heard speech. It captures cognitive aspects of listening related to sentence comprehension that are quantitatively and qualitatively different from working memory capacity. Visual information provided in the audiovisual modality of presentation can hinder executive processing in working memory of nondegraded speech material.

    Visual Cues Contribute Differentially to Audiovisual Perception of Consonants and Vowels in Improving Recognition and Reducing Cognitive Demands in Listeners With Hearing Impairment Using Hearing Aids2017Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 60, nr 9, s. 2687-2703Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose We sought to examine the contribution of visual cues in audiovisual identification of consonants and vowels—in terms of isolation points (the shortest time required for correct identification of a speech stimulus), accuracy, and cognitive demands—in listeners with hearing impairment using hearing aids.

    Method The study comprised 199 participants with hearing impairment (mean age = 61.1 years) with bilateral, symmetrical, mild-to-severe sensorineural hearing loss. Gated Swedish consonants and vowels were presented aurally and audiovisually to participants. Linear amplification was adjusted for each participant to assure audibility. The reading span test was used to measure participants' working memory capacity.

    Results Audiovisual presentation resulted in shortened isolation points and improved accuracy for consonants and vowels relative to auditory-only presentation. This benefit was more evident for consonants than vowels. In addition, correlations and subsequent analyses revealed that listeners with higher scores on the reading span test identified both consonants and vowels earlier in auditory-only presentation, but only vowels (not consonants) in audiovisual presentation.

    Conclusion Consonants and vowels differed in terms of the benefits afforded from their associative visual cues, as indicated by the degree of audiovisual benefit and reduction in cognitive demands linked to the identification of consonants and vowels presented audiovisually.

    Shared etiology of phonological memory and vocabulary deficits in school-age children2013Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 56, nr 4, s. 1249-1259Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: The goal of this study was to investigate the etiologic basis for the association between deficits in phonological memory (PM) and vocabulary in school-age children.

    Method: Children with deficits in PM or vocabulary were identified within the International Longitudinal Twin Study (ILTS; Samuelsson et al., 2005). The ILTS includes 1,045 twin pairs (between the ages of 5 and 8 years) from the United States, Australia, and Scandinavia. The authors applied the DeFries-Fulker ( DeFries & Fulker, 1985, 1988) regression method to determine whether problems in PM and vocabulary tend to co-occur because of overlapping genes, overlapping environmental risk factors, or both.

    Results: Among children with isolated PM deficits, the authors found significant bivariate heritability of PM and vocabulary weaknesses both within and across time. However, when probands were selected for a vocabulary deficit, there was no evidence for bivariate heritability. In this case, it appears that the PM–vocabulary relationship is caused by common shared environmental experiences.

    Conclusions: The findings are consistent with previous research on the heritability of specific language impairment and suggest that there are etiologic subgroups of children with low vocabulary for different reasons, 1 being more influenced by genes and another being more influenced by environment.

    Seeing the talker’s face improves free recall of speech for young adults with normal hearing but not older adults with hearing loss2016Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 59, s. 590-599Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose Seeing the talker's face improves speech understanding in noise, possibly releasing resources for cognitive processing. We investigated whether it improves free recall of spoken two-digit numbers.

    Method Twenty younger adults with normal hearing and 24 older adults with hearing loss listened to and subsequently recalled lists of 13 two-digit numbers, with alternating male and female talkers. Lists were presented in quiet as well as in stationary and speech-like noise at a signal-to-noise ratio giving approximately 90% intelligibility. Amplification compensated for loss of audibility.

    Results Seeing the talker's face improved free recall performance for the younger but not the older group. Poorer performance in background noise was contingent on individual differences in working memory capacity. The effect of seeing the talker's face did not differ in quiet and noise.

    Conclusions We have argued that the absence of an effect of seeing the talker's face for older adults with hearing loss may be due to modulation of audiovisual integration mechanisms caused by an interaction between task demands and participant characteristics. In particular, we suggest that executive task demands and interindividual executive skills may play a key role in determining the benefit of seeing the talker's face during a speech-based cognitive task

    Poorer Speech Reception Threshold in Noise Is Associated With Lower Brain Volume in Auditory and Cognitive Processing Regions2019Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 62, nr 4, s. 1117-1130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: Hearing loss is associated with changes in brain volume in regions supporting auditory and cognitive processing. The purpose of this study was to determine whether there is a systematic association between hearing ability and brain volume in cross-sectional data from a large nonclinical cohort of middle-aged adults available from the UK Biobank Resource (http://www.ukbiobank.ac.uk). Method: We performed a set of regression analyses to determine the association between speech reception threshold in noise (SRTn) and global brain volume as well as predefined regions of interest (ROIs) based on T1-weighted structural images, controlling for hearing-related comorbidities and cognition as well as demographic factors. In a 2nd set of analyses, we additionally controlled for hearing aid (HA) use. We predicted statistically significant associations globally and in ROIs including auditory and cognitive processing regions, possibly modulated by HA use. Results: Whole-brain gray matter volume was significantly lower for individuals with poorer SRTn. Furthermore, the volume of 9 predicted ROIs including both auditory and cognitive processing regions was lower for individuals with poorer SRTn. The greatest percentage difference (-0.57%) in ROI volume relating to a 1 SD worsening of SRTn was found in the left superior temporal gyrus. HA use did not substantially modulate the pattern of association between brain volume and SRTn. Conclusions: In a large middle-aged nonclinical population, poorer hearing ability is associated with lower brain volume globally as well as in cortical and subcortical regions involved in auditory and cognitive processing, but there was no conclusive evidence that this effect is moderated by HA use. This pattern of results supports the notion that poor hearing leads to reduced volume in brain regions recruited during speech understanding under challenging conditions. These findings should be tested in future longitudinal, experimental studies.

    A speechreading expert. The case of MM.1999Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 42, s. 5-20Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The present case study of MM, who acquired both sign languageand spoken language in her early preschool years—and thenreached the normal milestones of development in each language—revealedthat her speechreading expertise is associated with cognitivefunctions such as high working memory capacity and phonologicalskills. Her cognitive profile is in accord with previous casestudies of extremely good speechreading skill. MM's enhancedright prefrontal/frontal cerebral blood flow activation duringspeechreading seems to be indicative of efficient visual scanning,but it is also possibly due to her strategy for phonologicaldecoding of visual speech.

    Hearing Loss Is Negatively Related to Episodic and Semantic Long-Term Memory but Not to Short-Term Memory2011Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 54, nr April, s. 705-726Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To test the relationship between degree of hearing loss anddifferent memory systems in hearing aid users.

    Method: Structural equation modeling (SEM) was used to study the relationshipbetween auditory and visual acuity and different cognitive andmemory functions in an age-hetereogenous subsample of 160 hearingaid users without dementia, drawn from the Swedish prospectivecohort aging study known as Betula (L.-G. Nilsson et al., 1997).

    Results: Hearing loss was selectively and negatively related to episodicand semantic long-term memory (LTM) but not short-term memory(STM) performance. This held true for both ears, even when agewas accounted for. Visual acuity alone, or in combination withauditory acuity, did not contribute to any acceptable SEM solution.

    Conclusions: The overall relationships between hearing loss and memory systemswere predicted by the ease of language understanding model (J. Rönnberg, 2003), but the exact mechanisms of episodicmemory decline in hearing aid users (i.e., mismatch/disuse,attentional resources, or information degradation) remain openfor further experiments. The hearing aid industry should striveto design signal processing algorithms that are cognition friendly.

    Episodic long-term memory of spoken discourse masked by speech: what is the role for working memory capacity?2012Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 55, nr 1, s. 210-218Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To investigate whether working memory capacity (WMC) modulates the effects of to-be-ignored speech on the memory of materials conveyed by to-be-attended speech.

    Method: Two tasks (reading span and size-comparison span) were used to measure individual differences in WMC. Episodic long-term memory of spoken discourse was measured by requesting participants to listen to stories masked either by a normal speech or by a rotated version of that speech and subsequently answer questions on the content of the stories.

    Results: Normal speech impaired performance on the episodic long-term memory test, and both WMC-tasks were negatively related to this effect, indicating that high-WMC individuals are less susceptible to disruption. Moreover, further analyses revealed that size-comparison span (a task that requires resolution of semantic confusion by inhibition processes) is a stronger predictor of the effect than reading span is.

    Conclusions: Cognitive control processes support listening in adverse conditions. In particular, inhibition processes acting to resolve semantic confusion seem to underlie the relationship between WMC and susceptibility to distraction from masking speech.

    Task Difficulty Differentially Affects Two Measures of Processing Load: The Pupil Response During Sentence Processing and Delayed Cued Recall of the Sentences2013Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 56, nr 4, s. 1156-1165Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: In this study, the authors assessed the influence of masking level (29% or 71% sentence perception) and test modality on the processing load during language perception as reflected by the pupil response. In addition, the authors administered a delayed cued stimulus recall test to examine whether processing load affected the encoding of the stimuli in memory. less thanbrgreater than less thanbrgreater thanMethod: Participants performed speech and text reception threshold tests, during which the pupil response was measured. In the cued recall test, the first half of correctly perceived sentences was presented, and participants were asked to complete the sentences. Reading and listening span tests of working memory capacity were presented as well. less thanbrgreater than less thanbrgreater thanResults: Regardless of test modality, the pupil response indicated higher processing load in the 29% condition than in the 71% correct condition. Cued recall was better for the 29% condition. less thanbrgreater than less thanbrgreater thanConclusions: The consistent effect of masking level on the pupil response during listening and reading support the validity of the pupil response as a measure of processing load during language perception. The absent relation between pupil response and cued recall may suggest that cued recall is not directly related to processing load, as reflected by the pupil response.

Regression analyses examined the predictive value of age, hearing thresholds (pure-tone averages [PTAs]), speech perception in noise (speech reception thresholds in noise [SRTNs]), and the cognitive tests for the 5 AIADH factors. less thanbrgreater than less thanbrgreater thanResults: Besides the variance explained by age, PTA, and SRTN, cognitive abilities were related to each hearing factor. The reported difficulties with sound detection and speech perception in quiet were less severe for participants with higher age, lower PTAs, and better TRTs. Fewer sound localization and speech perception in noise problems were reported by participants with better SRTNs and smaller SWM. Fewer sound discrimination difficulties were reported by subjects with better SRTNs and TRTs and smaller SWM. less thanbrgreater than less thanbrgreater thanConclusions: The results suggest a general role of the ability to read partly masked text in subjective hearing. Large working memory was associated with more reported hearing difficulties. This study shows that besides auditory variables and age, cognitive abilities are related to self-reported hearing disability.

    Reading Behind the Lines: The Factors Affecting the Text Reception Threshold in Hearing Aid Users.2018Inngår i: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 61, nr 3, s. 762-775Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: The visual Text Reception Threshold (TRT) test (Zekveld et al., 2007) has been designed to assess modality-general factors relevant for speech perception in noise. In the last decade, the test has been adopted in audiology labs worldwide. The 1st aim of this study was to examine which factors best predict interindividual differences in the TRT. Second, we aimed to assess the relationships between the TRT and the speech reception thresholds (SRTs) estimated in various conditions.; Method: First, we reviewed studies reporting relationships between the TRT and the auditory and/or cognitive factors and formulated specific hypotheses regarding the TRT predictors. These hypotheses were tested using a prediction model applied to a rich data set of 180 hearing aid users. In separate association models, we tested the relationships between the TRT and the various SRTs and subjective hearing difficulties, while taking into account potential confounding variables.; Results: The results of the prediction model indicate that the TRT is predicted by the ability to fill in missing words in incomplete sentences, by lexical access speed, and by working memory capacity. Furthermore, in line with previous studies, a moderate association between higher age, poorer pure-tone hearing acuity, and poorer TRTs was observed. Better TRTs were associated with better SRTs for the correct perception of 50% of Hagerman matrix sentences in a 4-talker babble, as well as with better subjective ratings of speech perception. Age and pure-tone hearing thresholds significantly confounded these associations. The associations of the TRT with SRTs estimated in other conditions and with subjective qualities of hearing were not statistically significant when adjusting for age and pure-tone average.; Conclusions: We conclude that the abilities tapped into by the TRT test include processes relevant for speeded lexical decision making when completing partly masked sentences and that these processes require working memory capacity. Furthermore, the TRT is associated with the SRT of hearing aid users as estimated in a challenging condition that includes informational masking and with experienced difficulties with speech perception in daily-life conditions. The current results underline the value of using the TRT test in studies involving speech perception and aid in the interpretation of findings acquired using the test.
