  • Auditory Distraction in ADHD : From Behaviour to the Brain
  • 2022
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • ADHD is a heterogenous disorder encompassing neurodevelopmental deficits in cognitive control. Auditory distraction is a common clinically reported symptom in ADHD, yet empirical research investigating the manifestation of auditory distraction in the disorder is remarkably scarce. Findings from cognitive hearing science highlight the crucial role cognitive control plays in an individual’s ability to gate, attenuate and/or compensate for auditory distraction. However the field is yet to extensively test hypotheses in normal hearing populations with neurodevelopmental deficits in cognitive control such as ADHD. This thesis contributes to narrowing the gap within these two fields of research by studying auditory distraction in this clinical population to a greater extent than previous reports in the literature.Using a combination of both behavioural and neuroimaging methods, the research presented here was able to show that adults and adolescents with ADHD are inherently more susceptible to auditory distraction than their non-ADHD counterparts. At the behavioural level, impaired task performance due to auditory distraction was more likely to manifest in ADHD participants when the working memory system was under high processing load. At the neural level, functional aberrancy in auditory attention was evident at early stages of sensory processing in a variety of tasks, implicating both exogenous and endogenous control systems in ADHD. Furthermore, the distribution of ADHD-symptom severity across participants was shown to correlate with increases in both cortical activity to auditory distractors and intrinsic functional connectivity between auditory and exogenous attention networks.In line with evidence from cognitive hearing science, the general findings of this thesis demonstrate that cognitive control plays an important role in the ability to perceive sound under suboptimal listening conditions and hamper distraction. In addition, findings challenge theories of ADHD that question the extent in which sensory-related attentional control is impaired. More empirical research on the auditory modality in ADHD is therefore encouraged in order to revise models, improve diagnostic tools, and develop evidence-based interventions targeting study/work environments.

  • Neurobiological insights from the study of deafness and sign language
  • 2019
  • Ingår i: Understanding deafness, language, and cognitive development. - Amsterdam : John Benjamins Publishing Company. - 9789027204493 - 9789027261861 ; , s. 159-181
  • Bokkapitel (refereegranskat)abstract
    • The study of deafness and sign language has provided a means of dissociating modality specificity from higher level abstract processes in the brain. Differentiating these is fundamental for establishing the relationship between sensorimotor representations and functional specialisation in the brain. Early deafness in humans provides a unique insight into this problem, because the reorganisation observed in the adult deaf brain is not only due to neural development in the absence of auditory inputs, but also due to the acquisition of visual communication strategies such as sign language and speechreading. Here we report research by scholars who have collaborated with Bencie Woll in understanding the neural reorganisation that occurs as a consequence of early deafness, and its relation to the use of different visual strategies for language. We concentrate on three main topics: functional specialisation of sensory cortices, language and working memory.

  • Facial mimicry interference reduces working memory accuracy for facial emotion expressions
  • 2024
  • Ingår i: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 19:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Facial mimicry, the tendency to imitate facial expressions of other individuals, has been shown to play a critical role in the processing of emotion expressions. At the same time, there is evidence suggesting that its role might change when the cognitive demands of the situation increase. In such situations, understanding another person is dependent on working memory. However, whether facial mimicry influences working memory representations for facial emotion expressions is not fully understood. In the present study, we experimentally interfered with facial mimicry by using established behavioral procedures, and investigated how this interference influenced working memory recall for facial emotion expressions. Healthy, young adults (N = 36) performed an emotion expression n-back paradigm with two levels of working memory load, low (1-back) and high (2-back), and three levels of mimicry interference: high, low, and no interference. Results showed that, after controlling for block order and individual differences in the perceived valence and arousal of the stimuli, the high level of mimicry interference impaired accuracy when working memory load was low (1-back) but, unexpectedly, not when load was high (2-back). Working memory load had a detrimental effect on performance in all three mimicry conditions. We conclude that facial mimicry might support working memory for emotion expressions when task load is low, but that the supporting effect possibly is reduced when the task becomes more cognitively challenging.

  • A structural equation mediation model captures the predictions amongst the parameters of the ease of language understanding model
  • 2023
  • Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 14
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The aim of the present study was to assess the validity of the Ease of Language Understanding (ELU) model through a statistical assessment of the relationships among its main parameters: processing speed, phonology, working memory (WM), and dB Speech Noise Ratio (SNR) for a given Speech Recognition Threshold (SRT) in a sample of hearing aid users from the n200 database.Methods: Hearing aid users were assessed on several hearing and cognitive tests. Latent Structural Equation Models (SEMs) were applied to investigate the relationship between the main parameters of the ELU model while controlling for age and PTA. Several competing models were assessed.Results: Analyses indicated that a mediating SEM was the best fit for the data. The results showed that (i) phonology independently predicted speech recognition threshold in both easy and adverse listening conditions and (ii) WM was not predictive of dB SNR for a given SRT in the easier listening conditions (iii) processing speed was predictive of dB SNR for a given SRT mediated via WM in the more adverse conditions.Conclusion: The results were in line with the predictions of the ELU model: (i) phonology contributed to dB SNR for a given SRT in all listening conditions, (ii) WM is only invoked when listening conditions are adverse, (iii) better WM capacity aids the understanding of what has been said in adverse listening conditions, and finally (iv) the results highlight the importance and optimization of processing speed in conditions when listening conditions are adverse and WM is activated.

  • Is Having Hearing Loss Fundamentally Different? : Multigroup Structural Equation Modeling of the Effect of Cognitive Functioning on Speech Identificatio
  • 2022
  • Ingår i: Ear and Hearing. - : Lippincott Williams & Wilkins. - 0196-0202 .- 1538-4667. ; 43:5, s. 1437-1446
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Previous research suggests that there is a robust relationship between cognitive functioning and speech-in-noise performance for older adults with age-related hearing loss. For normal-hearing adults, on the other hand, the research is not entirely clear. Therefore, the current study aimed to examine the relationship between cognitive functioning, aging, and speech-in-noise, in a group of older normal-hearing persons and older persons with hearing loss who wear hearing aids.Design: We analyzed data from 199 older normal-hearing individuals (mean age = 61.2) and 200 older individuals with hearing loss (mean age = 60.9) using multigroup structural equation modeling. Four cognitively related tasks were used to create a cognitive functioning construct: the reading span task, a visuospatial working memory task, the semantic word-pairs task, and Raven’s progressive matrices. Speech-in-noise, on the other hand, was measured using Hagerman sentences. The Hagerman sentences were presented via an experimental hearing aid to both normal hearing and hearing-impaired groups. Furthermore, the sentences were presented with one of the two background noise conditions: the Hagerman original speech-shaped noise or four-talker babble. Each noise condition was also presented with three different hearing processing settings: linear processing, fast compression, and noise reduction.Results: Cognitive functioning was significantly related to speech-in-noise identification. Moreover, aging had a significant effect on both speech-in-noise and cognitive functioning. With regression weights constrained to be equal for the two groups, the final model had the best fit to the data. Importantly, the results showed that the relationship between cognitive functioning and speech-in-noise was not different for the two groups. Furthermore, the same pattern was evident for aging: the effects of aging on cognitive functioning and aging on speech-in-noise were not different between groups.Conclusion: Our findings revealed similar cognitive functioning and aging effects on speech-in-noise performance in older normal-hearing and aided hearing-impaired listeners. In conclusion, the findings support the Ease of Language Understanding model as cognitive processes play a critical role in speech-in-noise independent from the hearing status of elderly individuals.

  • Time to Plan : How to support everyday planning in adolescents with intellectual disability
  • 2020
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Children and adolescents with intellectual disability (ID) have difficulties in executive functioning and when coping with everyday planning tasks. However, the literature cannot explain whether individuals with ID perform according to their developmental level or not. The studies in this thesis investigated if life experience could be a contributing factor to the diversity seen in the literature. Planning performance can be improved by either using external or internal support. Assistive technology for cognition (ATC) is an example of external support. This thesis investigated how the ATC is being used in an everyday planning situation which has not been investigated before. Furthermore, this thesis explored whether the internal supports of cognitive abilities and life experience correlate with planning ability in adolescents with ID, and if planning ability can be trained using a cognitive training program for everyday planning. Results showed that ATC supported cognitive functions, but that the children did not formulate the plans themselves. Furthermore, the results support the difference model of ID since planning correlated with different cognitive measures and life experience in adolescents with ID compared to children with a typical development. Adolescents with ID got better at the planning tasks in the training program, however, no transfer effects to untrained planning tasks were found. To conclude, the planning was supported by external and internal support. However, ATC needs to be designed and prescribed in a way that increases independence. Practitioners should actively support in training planning and should be cautious when introducing cognitive interventions if the transfer gap is too large.

  • Cognitive Hearing Science: Three Memory Systems, Two Approaches, and the Ease of Language Understanding Model
  • 2021
  • Ingår i: Journal of Speech, Language, and Hearing Research. - : American Speech-Language-Hearing Association. - 1558-9102. ; 64:2, s. 359-370
  • Tidskriftsartikel (refereegranskat)abstract
    • PurposeThe purpose of this study was to conceptualize the subtle balancing act between language input and prediction (cognitive priming of future input) to achieve understanding of communicated content. When understanding fails, reconstructive postdiction is initiated. Three memory systems play important roles: working memory (WM), episodic long-term memory (ELTM), and semantic long-term memory (SLTM). The axiom of the Ease of Language Understanding (ELU) model is that explicit WM resources are invoked by a mismatch between language input—in the form of rapid automatic multimodal binding of phonology—and multimodal phonological and lexical representations in SLTM. However, if there is a match between rapid automatic multimodal binding of phonology output and SLTM/ELTM representations, language processing continues rapidly and implicitly.Method and ResultsIn our first ELU approach, we focused on experimental manipulations of signal processing in hearing aids and background noise to cause a mismatch with LTM representations; both resulted in increased dependence on WM. Our second—and main approach relevant for this review article—focuses on the relative effects of age-related hearing loss on the three memory systems. According to the ELU, WM is predicted to be frequently occupied with reconstruction of what was actually heard, resulting in a relative disuse of phonological/lexical representations in the ELTM and SLTM systems. The prediction and results do not depend on test modality per se but rather on the particular memory system. This will be further discussed.ConclusionsRelated to the literature on ELTM decline as precursors of dementia and the fact that the risk for Alzheimer's disease increases substantially over time due to hearing loss, there is a possibility that lowered ELTM due to hearing loss and disuse may be part of the causal chain linking hearing loss and dementia. Future ELU research will focus on this possibility.
