    Cognition in hearing aid users2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Cognitive abilities vary between individuals and have been shown to be related to hearing aidbenet. How individual dierences in cognitive abilities interact with signal processing to reducelistening eort will be discussed in this presentation. Two studies were performed to investigate theeect of a hearing aid signal processing algorithm on free recall of speech heard in noise in hearingaid users, and the role of cognition. The specic aims were to develop a free recall test to measurethis eect and to test whether the eect would interact with background noise and/or individualdierences in cognitive capacity. Results demonstrated that noise impairs the ability to recall intelligiblespeech heard in noise. Noise reduction freed up cognitive resources and alleviated the negativeimpact of noise on memory when speech stimuli were presented in background noise consisting ofspeech babble. The possible underlying mechanisms are that noise reduction facilitates segregationof the auditory stream into target and irrelevant speech and reduces the capture of attention bythe linguistic information in irrelevant speech. In both studies, the eect of noise reduction on freerecall performance was modulated by individual dierences in cognitive capacity, suggesting that themechanism by which noise reduction facilitates free recall on speech heard in noise is dependent onworking memory capacity.

    Differences in temporal and spatial processing mechanisms in working memory for signed and spoken language2009Inngår i: The 11th European congress of Psychology, Oslo, Norway, 7-10 July 2009.,2009, 2009Konferansepaper (Fagfellevurdert)
    Abstract [en]

     Objectives Working memory (WM) capacity is similar for signed (SL) and spoken (SpL) language yet underlying temporal and spatial processing mechanisms may not be identical. To investigate this, two studies with deaf native signers (DS) and hearing non-signers (HN) were conducted. Methods DS and matched HN groups performed WM tasks with varying temporal and spatial demands in study 1 at encoding (temporal, spatial and mixed presentation styles) and in study 2 at retrieval (forward and backward span) and with abstract spatial demands (math span). Results DS performance was inferior with high temporal demands at encoding (temporal style) and retreival (forward span). There was no difference between groups with high spatial order demands at encoding (spatial style) or retrieval (backward span). DS performance was worse when abstract spatial processing was involved (math span). Conclusion WM processing mechanisms for SL and SpL differ for temporal information at encoding and retrieval and for abstract spatial information.

    Working memory, deafness and sign language.2009Inngår i: Scandinavian journal of psychology, ISSN 1467-9450, Vol. 50, nr 5, s. 495-505Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Working memory (WM) for sign language has an architecture similar to that for speech-based languages at both functional and neural levels. However, there are some processing differences between language modalities that are not yet fully explained, although a number of hypotheses have been mooted. This article reviews some of the literature on differences in sensory, perceptual and cognitive processing systems induced by auditory deprivation and sign language use and discusses how these differences may contribute to differences in WM architecture for signed and speech-based languages. In conclusion, it is suggested that left-hemisphere reorganization of the motion-processing system as a result of native sign-language use may interfere with the development of the order processing system in WM.

    Training Literacy Skills through Sign Language2014Inngår i: Deafness and Education International, ISSN 1464-3154, E-ISSN 1557-069X, Vol. 17, nr 1, s. 8-18Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The literacy skills of deaf children generally lag behind those of their hearing peers. The mechanisms of reading in deaf individuals are only just beginning to be unraveled but it seems that native language skills play an important role. In this study 12 deaf pupils (six in grades 1?2 and six in grades 4?6) at a Swedish state primary school for deaf and hard of hearing children were trained on the connection between Swedish Sign Language and written Swedish using a pilot sign language version of the literacy training software program Omega-is. Literacy skills improved substantially across the 20 days of the study. These literacy gains may have rested upon the specific software-based intervention, upon regular classroom activities, or upon a combination of these factors. Omega-is-d, and similar software utilizing sign language as a component, targets an important mechanism supporting reading development in deaf children and could play an important role in bilingual education refinements.

    Effects of Age on the Temporal Organization of Working Memory in Deaf Signers2010Inngår i: AGING NEUROPSYCHOLOGY AND COGNITION, ISSN 1382-5585, Vol. 17, nr 3, s. 360-383Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Deaf native signers have a general working memory (WM) capacity similar to that of hearing non-signers but are less sensitive to the temporal order of stored items at retrieval. General WM capacity declines with age, but little is known of how cognitive aging affects WM function in deaf signers. We investigated WM function in elderly deaf signers (EDS) and an age-matched comparison group of hearing non-signers (EHN) using a paradigm designed to highlight differences in temporal and spatial processing of item and order information. EDS performed worse than EHN on both item and order recognition using a temporal style of presentation. Reanalysis together with earlier data showed that with the temporal style of presentation, order recognition performance for EDS was also lower than for young adult deaf signers. Older participants responded more slowly than younger participants. These findings suggest that apart from age-related slowing irrespective of sensory and language status, there is an age-related difference specific to deaf signers in the ability to retain order information in WM when temporal processing demands are high. This may be due to neural reorganisation arising from sign language use. Concurrent spatial information with the Mixed style of presentation resulted in enhanced order processing for all groups, suggesting that concurrent temporal and spatial cues may enhance learning for both deaf and hearing groups. These findings support and extend the WM model for Ease of Language Understanding.

    Aided speech recognition in noise, perceived effort and explicit cognitive capacity2008Inngår i: International Hearing Aid Research Conference IHCON 2008, Lake Tahoe, California, 13-17 August 2008.,2008, 2008Konferansepaper (Fagfellevurdert)
    Abstract [en]

     Speech recognition in noise is an effortful process requiring explicit cognitive processing. It may be influenced by level and type of noise and by the signal processing algorithms employed when hearing is aided. These complex relationships may be understood in terms of the working memory model for Ease of language Understanding (ELU, Rönnberg et al., in press). This model predicts that under challenging listening conditions, explicit cognitive processing demands will be high and that persons with good explicit cognitive capacity will be better listeners. Previous work has suggested that they may also find listening less effortful (Behrens et al., 2004; Larsby et al., 2005; in press). We studied this issue by including subjective effort ratings in a larger study designed to investigate aided speech recognition in noise and cognition. 32 experienced hearing aid users participated. Effort was rated using a visual analogue scale and the speech material was the Hagerman sentences presented in three fixed speech to noise ratios of +10 dB, +4 dB and -2dB. Effort was rated in modulated and unmodulated noise with fast and slow compression release settings, after each of two nine week training sessions with the same settings. Speech recognition performance was tested objectively under the same conditions using an adaptive procedure. Order of testing was balanced. Explicit cognitive capacity was measured using the reading span test. ANOVAs and correlations were computed. Preliminary results showed that decreasing SNR led to greater perceived effort and that the difference in perceived effort between the highest and the lowest SNR was greater in unmodulated noise than in modulated noise. Speech recognition performance in unmodulated noise generally correlated with effort ratings under similar conditions but in modulated noise generally it did not. Effort ratings correlated with reading span performance at the lowest SNR (-2dB) but only in unmodulated noise after the first training session. These preliminary findings show that subjective ratings of the effort involved in aided speech recognition covary with noise level and performance but that these effects are reduced by noise modulation. Further, the perceived effort of aided speech recognition at low SNR may be related to explicit cognitive capacity as measured by the reading span test. However, we only find evidence of this in unmodulated noise after the first training session. These findings extend previous work on perceived effort and cognitive capacity and provide further evidence that type of noise is an important factor in this relationship.

    Cognition and aided speech recognition in noise: specific role for cognitive factors following nine-week experience with adjusted compression settings in hearing aids.2009Inngår i: Scandinavian journal of psychology, ISSN 1467-9450, Vol. 50, nr 5, s. 405-418Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The working memory model for Ease of Language Understanding (ELU) proposes that language understanding under taxing conditions is related to explicit cognitive capacity. We refer to this as the mismatch hypothesis, since phonological representations based on the processing of speech under established conditions may not be accessed so readily when input conditions change and a match becomes problematic. Then, cognitive capacity requirements may differ from those used for processing speech hitherto. In the present study, we tested this hypothesis by investigating the relationship between aided speech recognition in noise and cognitive capacity in experienced hearing aid users when there was either a match or mismatch between processed speech input and established phonological representations. The settings in the existing digital hearing aids of the participants were adjusted to one of two different compression settings which processed the speech signal in qualitatively different ways ("fast" or "slow"). Testing took place after a 9-week period of experience with the new setting. Speech recognition was tested under different noise conditions and with match or mismatch (i.e. alternative compression setting) manipulations of the input signal. Individual cognitive capacity was measured using a reading span test and a letter monitoring test. Reading span, a reliable measure of explicit cognitive capacity, predicted speech recognition performance under mismatch conditions when processed input was incongruent with recently established phonological representations, due to the specific hearing aid setting. Cognitive measures were not main predictors of performance under match conditions. These findings are in line with the ELU model.

    Phonological mismatch makes aided speech recognition in noise cognitively taxing2007Inngår i: Ear and Hearing, ISSN 0196-0202, E-ISSN 1538-4667, Vol. 28, s. 879-892Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: The working memory framework for Ease of Language Understanding predicts that speech processing becomes more effortful, thus requiring more explicit cognitive resources, when there is mismatch between speech input and phonological representations in long-term memory. To test this prediction, we changed the compression release settings in the hearing instruments of experienced users and allowed them to train for 9 weeks with the new settings. After training, aided speech recognition in noise was tested with both the trained settings and orthogonal settings. We postulated that training would lead to acclimatization to the trained setting, which in turn would involve establishment of new phonological representations in long-term memory. Further, we postulated that after training, testing with orthogonal settings would give rise to phonological mismatch, associated with more explicit cognitive processing.

    Design: Thirty-two participants (mean = 70.3 years, SD = 7.7) with bilateral sensorineural hearing loss (pure-tone average = 46.0 dB HL, SD = 6.5), bilaterally fitted for more than 1 year with digital, two-channel, nonlinear signal processing hearing instruments and chosen from the patient population at the Linkooping University Hospital were randomly assigned to 9 weeks training with new, fast (40 ms) or slow (640 ms), compression release settings in both channels. Aided speech recognition in noise performance was tested according to a design with three within-group factors: test occasion (T1, T2), test setting (fast, slow), and type of noise (unmodulated, modulated) and one between-group factor: experience setting (fast, slow) for two types of speech materials-the highly constrained Hagerman sentences and the less-predictable Hearing in Noise Test (HINT). Complex cognitive capacity was measured using the reading span and letter monitoring tests.

    Prediction: We predicted that speech recognition in noise at T2 with mismatched experience and test settings would be associated with more explicit cognitive processing and thus stronger correlations with complex cognitive measures, as well as poorer performance if complex cognitive capacity was exceeded.

    Results: Under mismatch conditions, stronger correlations were found between performance on speech recognition with the Hagerman sentences and reading span, along with poorer speech recognition for participants with low reading span scores. No consistent mismatch effect was found with HINT.

    Conclusions: The mismatch prediction generated by the working memory framework for Ease of Language Understanding is supported for speech recognition in noise with the highly constrained Hagerman sentences but not the less-predictable HINT.

    Neural representation of binding lexical signs and words in the episodic buffer of working memory2007Inngår i: Neuropsychologia, ISSN 0028-3932, E-ISSN 1873-3514, Vol. 45, nr 10, s. 2258-2276Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The episodic buffer accommodates formation and maintenance of unitary multidimensional representations based on information in different codes from different sources. Formation, based on submorphemic units, engages posterior brain regions, while maintenance engages frontal regions. Using a hybrid fMRI design, that allows separate analysis of transient and sustained components, an n-back task and an experimental group of 13 hearing native signers, with experience of Swedish Sign Language and Swedish since birth, we investigated binding of lexical signs and words in working memory. Results show that the transient component of these functions is supported by a buffer-specific network of posterior regions including the right middle temporal lobe, possibly relating to binding of phonological loop representations with semantic representations in long-term memory, as well as a loop-specific network, in line with predictions of a functional relationship between loop and buffer. The left hippocampus was engaged in transient and sustained components of buffer processing, possibly reflecting the meaningful nature of the stimuli. Only a minor role was found for executive functions in line with other recent work. A novel representation of the sustained component of working memory for audiovisual language in the right inferior temporal lobe may be related to perception of speech-related facial gestures. Previous findings of sign and speech loop representation in working memory were replicated and extended. Together, these findings support the notion of a module that mediates between codes and sources, such as the episodic buffer, and further our understanding of its nature.

    Phonological mismatch and explicit cognitive processing in a sample of 102 hearing-aid users2008Inngår i: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 47, nr 2, s. S91-S98Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Rudner et al (2008) showed that when compression release settings are manipulated in the hearing instruments of Swedish habitual users, the resulting mismatch between the phonological form of the input speech signal and representations stored in long-term memory leads to greater engagement of explicit cognitive processing under taxing listening conditions. The mismatch effect is manifest in significant correlations between performance on cognitive tests and aided-speech-recognition performance in modulated noise and/or with fast compression release settings. This effect is predicted by the ELU model (Ronnberg et al, 2008). In order to test whether the mismatch effect can be generalized across languages, we examined two sets of aided speech recognition data collected from a Danish population where two cognitive tests, reading span and letter monitoring, had been administered. A reanalysis of all three datasets, including 102 participants, demonstrated the mismatch effect. These findings suggest that the effect of phonological mismatch, as predicted by the ELU model (Ronnberg et al, this issue) and tapped by the reading span test, is a stable phenomenon across these two Scandinavian languages.

    Levels of processing and language modality specificity in working memory2013Inngår i: Neuropsychologia, ISSN 0028-3932, E-ISSN 1873-3514, Vol. 51, nr 4, s. 656-666Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Neural networks underpinning working memory demonstrate sign language specific components possibly related to differences in temporary storage mechanisms. A processing approach to memory systems suggests that the organisation of memory storage is related to type of memory processing as well. In the present study, we investigated for the first time semantic, phonological and orthographic processing in working memory for sign- and speech-based language. During fMRI we administered a picture-based 2-back working memory task with Semantic, Phonological, Orthographic and Baseline conditions to 11 deaf signers and 20 hearing non-signers. Behavioural data showed poorer and slower performance for both groups in Phonological and Orthographic conditions than in the Semantic condition, in line with depth-of-processing theory. An exclusive masking procedure revealed distinct sign-specific neural networks supporting working memory components at all three levels of processing. The overall pattern of sign-specific activations may reflect a relative intermodality difference in the relationship between phonology and semantics influencing working memory storage and processing.

    Semantic, phonological and orthographic processing in working memory for signed and speech-based language2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Working memory processing and maintenance components are supported by a fronto-parietal network that is largely similar, yet subtly different, for signed and speech-based languages. In the present study, we investigated for the first time modality-specific differences in the neural correlates of three different varieties of working memory processing (semantic, phonological and orthographic) in 11 deaf early users of Swedish Sign Language and 19 hearing native Swedish speakers using a picture-based 2-back fMRI paradigm. Contrasts between each of the processing levels and a 2-back, picture-based but non-linguistic baseline condition activated distinct networks between groups. In particular, the two groups activated only partially overlapping networks in regions previously associated with the three different kinds of processing. This suggests that the mechanisms supporting different varieties of working memory processing differ at least partially between modalities.

    Better visuospatial working memory in adults who report profound deafness compared to those with normal or poor hearing: data from the UK Biobank resource2016Inngår i: Ear and Hearing, ISSN 0196-0202, E-ISSN 1538-4667, Vol. 37, nr 5, s. 620-622Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Experimental work has shown better visuospatial working memory (VSWM) in profoundly deaf individuals compared to those with normal hearing. Other data, including the UK Biobank resource shows poorer VSWM in individuals with poorer hearing. Using the same database, the authors investigated VSWM in individuals who reported profound deafness. Included in this study were 112 participants who were profoundly deaf, 1310 with poor hearing and 74,635 with normal hearing. All participants performed a card-pair matching task as a test of VSWM. Although variance in VSWM performance was large among profoundly deaf participants, at group level it was superior to that of participants with both normal and poor hearing. VSWM in adults is related to hearing status but the association is not linear. Future study should investigate the mechanism behind enhanced VSWM in profoundly deaf adults.

    Working Memory Capacity May Influence Perceived Effort during Aided Speech Recognition in Noise2012Inngår i: JOURNAL OF THE AMERICAN ACADEMY OF AUDIOLOGY, ISSN 1050-0545, Vol. 23, nr 8, s. 577-589Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Recently there has been interest in using subjective ratings as a measure of perceived effort during speech recognition in noise. Perceived effort may be an indicator of cognitive load. Thus, subjective effort ratings during speech recognition in noise may covary both with signal-to-noise ratio (SNR) and individual cognitive capacity. less thanbrgreater than less thanbrgreater thanPurpose: The present study investigated the relation between subjective ratings of the effort involved in listening to speech in noise, speech recognition performance, and individual working memory (WM) capacity in hearing impaired hearing aid users. less thanbrgreater than less thanbrgreater thanResearch Design: In two experiments, participants with hearing loss rated perceived effort during aided speech perception in noise. Noise type and SNR were manipulated in both experiments, and in the second experiment hearing aid compression release settings were also manipulated. Speech recognition performance was measured along with WM capacity. less thanbrgreater than less thanbrgreater thanStudy Sample: There were 46 participants in all with bilateral mild to moderate sloping hearing loss. In Experiment 1 there were 16 native Danish speakers (eight women and eight men) with a mean age of 63.5 yr (SD = 12.1) and average pure tone (PT) threshold of 47. 6 dB (SD = 9.8). In Experiment 2 there were 30 native Swedish speakers (19 women and 11 men) with a mean age of 70 yr (SD = 7.8) and average PT threshold of 45.8 dB (SD = 6.6). less thanbrgreater than less thanbrgreater thanData Collection and Analysis: A visual analog scale (VAS) was used for effort rating in both experiments. In Experiment 1, effort was rated at individually adapted SNRs while in Experiment 2 it was rated at fixed SNRs. Speech recognition in noise performance was measured using adaptive procedures in both experiments with Dantale II sentences in Experiment 1 and Hagerman sentences in Experiment 2. WM capacity was measured using a letter-monitoring task in Experiment 1 and the reading span task in Experiment 2. less thanbrgreater than less thanbrgreater thanResults: In both experiments, there was a strong and significant relation between rated effort and SNR that was independent of individual WM capacity, whereas the relation between rated effort and noise type seemed to be influenced by individual WM capacity. Experiment 2 showed that hearing aid compression setting influenced rated effort. less thanbrgreater than less thanbrgreater thanConclusions: Subjective ratings of the effort involved in speech recognition in noise reflect SNRs, and individual cognitive capacity seems to influence relative rating of noise type.

    Good working memory capacity facilitates long-term memory encoding of speech in stationary noise2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background noise makes listening more cognitively demanding, especially for persons with hearingimpairment, and this seems to aect memory encoding. It is not clear whether this decrement can berestored by providing visual cues. In the present study, we investigated whether long term memoryencoding of speech, in quiet and in background noise adjusted to retain intelligibility, improves whenthe talkers face is visible, and whether such an enhancement is associated with working memorycapacity. Twenty adults with normal hearing in Experiment 1 and 24 adults with hearing loss inExperiment 2 listened to lists of 13 two-digit numbers, with or without seeing the talkers face, andthen recalled as many numbers as possible in any order. The lists were presented in quiet as wellin a steady-state speech-weighted noise and the International Speech Testing Signal at a signal-tonoiseratio individually adapted to give an intelligibility level of approximately 90%. Amplicationcompensated for loss of audibility. Working memory capacity was measured using the reading spantest. Seeing the talkers face did enhance free recall performance. However, whereas the eect size foradults with normal hearing was large, for adults with hearing impairment it was small. Further, therewas no evidence that visual cues specically compensated for performance decrements due to noiseor serial position and there was no evidence of an association between working memory capacity andperformance with visual cues. However, good working memory capacity did improve performance forearly list items, reecting facilitation of long-term memory encoding, for both groups when stimuliwere presented in steady-state noise. For participants with hearing impairment, good working memorycapacity was associated with good performance on late list items in quiet, reecting facilitationof working memory encoding. This pattern of results indicates that steady-state background noisereduces the cognitive capacity available for the long-term memory encoding of speech that is necessaryfor enduring retention of spoken information, irrespective of hearing status, but provides no evidencethat this is specically compensated for by visual cues. It also demonstrates that for individuals withhearing impairment, short term retention of speech heard even under the most favourable conditionsis a function of individual working memory capacity. These ndings support and extend the Ease ofLanguage Understanding Model.

    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

    Cognitive spare capacity as a measure of listening effort2011Inngår i: Journal of Hearing Science, ISSN 2083-389X, Vol. 1, nr 2, s. EA47-49Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There has been a recent interest in listening effort as a factor to be taken into account in the audiological clinic. However, the term “listening effort” is poorly determined and needs to be defined before it can be used as a clinical or research tool. One way of understanding listening effort is in terms of the cognitive resources expended during listening. Cognitive capacity is finite and thus if cognitive capacity is used up during the act of listening to speech there will be fewer cognitive resources left to process the content of the message conveyed. We have introduced the term Cognitive Spare Capacity (CSC) to refer to residual cognitive capacity once successful listening has taken place. This extended abstract described the work we have carried out to date on measures of CSC for research and clinical use. In the course of this work we have developed tests to assess the role of memory load, executive function and audiovisual integration in CSC under challenging conditions. When these tests are fully developed, our aim is that they should allow objective individual assessment of listening effort in cognitive terms. Results to date indicate that under challenging conditions, CSC is an arena for executive processing of temporarily stored information; it is related to individual working memory capacity and can be enhanced by hearing aid signal processing.

    Access to linguistic structure enhances visuospatial working memory capacity2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Verbal and visuospatial working memory (WM) have been widely studied but little is known about linguistic versus non-linguistic WM in the visuospatial domain. Sign languages (SL) are visuospatial languages that have a neurocognitive representation in deaf people similar to that of speech-based languages in hearing people. Thus SL can be used to study linguistic WM in the visuospatial domain. In the present study, SL stimuli were used as linguistic stimuli for signers and non-linguistic stimuli for non-signers to investigate how access to semantic and phonological representations of SL influences visuospatial WM. Materials were videos of a deaf signer modeling three types of sign-based stimuli and matched non-linguistic stimuli. 25 deaf native signers (DS) took part along with 25 hearing non-signers (HN) who could not access any linguistic content of the material. Sign-based stimuli were familiar signs (semantic and phonological content), unfamiliar signs (phonological but! no semantic content) and non-signs (illegal combinations of phonological components with no semantic content). All participants performed 2-back WM tasks, targeting either the identity (visual aspect) or location (spatial aspect) of the stimuli, with all four materials. In the identity task DS performed better than HN with sign-based materials but did not gain extra benefit from semantic or phonological content. In the location task DS benefited from semantic but not phonological content. These results show that signers can use linguistic knowledge in visuospatial WM tasks. Specifically, access to phonological components (sign-based material) supports identity processing and semantic content (familiar signs) supports location processing in visuospatial WM.
