In the present study we investigated temporal acuity for all possible bimodal pairings of visual, tactile and auditory information in adults with ASC (n?=?18) and a matched control group (n?=?18). No group differences in temporal acuity for crossmodal stimuli were observed, suggesting that this may be typical in adults with ASC. However, visual-tactile temporal acuity and bias towards vision when presented with visual-auditory information were both predictors of self-reported sensory reactivity. This suggests that reduced multisensory temporal acuity and/or attention towards vision may contribute to atypical sensory reactivity.

Chasing the conversation: Autistic experiences of speech perception / Alexandra STURROCK in Autism & Developmental Language Impairments, 7 (January-December 2022)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 7 (January-December 2022) Titre : Chasing the conversation: Autistic experiences of speech perception Type de document : Texte imprimé et/ou numérique Auteurs : Alexandra STURROCK, Auteur ; Hannah GUEST, Auteur ; Graham HANKS, Auteur ; George BENDO, Auteur ; Christopher J. PLACK, Auteur ; Emma GOWEN, Auteur Langues : Anglais (eng) Mots-clés : Autism spectrum  autistic  speech perception  auditory processing disorder  hyperacusis Index. décimale : PER Périodiques Résumé : Background and aimsHumans communicate primarily through spoken language and speech perception is a core function of the human auditory system. Among the autistic community, atypical sensory reactivity and social communication difficulties are pervasive, yet the research literature lacks in-depth self-report data on speech perception in this population. The present study aimed to elicit detailed first-person accounts of autistic individuals? abilities and difficulties perceiving the spoken word.MethodsSemi-structured interviews were conducted with nine autistic adults. The interview schedule addressed interviewees? experiences of speech perception, factors influencing those experiences, and responses to those experiences. Resulting interview transcripts underwent thematic analysis. The six-person study team included two autistic researchers, to reduce risk of neurotypical ?overshadowing? of autistic voices.ResultsMost interviewees reported pronounced difficulties perceiving speech in the presence of competing sounds. They emphasised that such listening difficulties are distinct from social difficulties, though the two can add and interact. Difficulties were of several varieties, ranging from powerful auditory distraction to drowning out of voices by continuous sounds. Contributing factors encompassed not only features of the soundscape but also non-acoustic factors such as multisensory processing and social cognition. Participants also identified compounding factors, such as lack of understanding of listening difficulties. Impacts were diverse and sometimes disabling, affecting socialising, emotions, fatigue, career, and self-image. A wide array of coping mechanisms was described.ConclusionsThe first in-depth qualitative investigation of autistic speech-perception experiences has revealed diverse and widespread listening difficulties. These can combine with other internal, interpersonal, and societal factors to induce profound impacts. Lack of understanding of such listening difficulties ? by the self, by communication partners, by institutions, and especially by clinicians ? appears to be a crucial exacerbating factor. Many autistic adults have developed coping strategies to lessen speech-perception difficulties or mitigate their effects, and these are generally self-taught due to lack of clinical support.ImplicationsThere is a need for carefully designed, adequately powered confirmatory research to verify, quantify, and disentangle the various forms of listening difficulty, preferably using large samples to explore heterogeneity. More immediate benefit might be obtained through development of self-help and clinical guidance materials, and by raising awareness of autistic listening experiences and needs, among the autistic community, communication partners, institutions, and clinicians.

Goal-Directed and Goal-Less Imitation in Autism Spectrum Disorder / Kelly S. WILD in Journal of Autism and Developmental Disorders, 42-8 (August 2012)

Our results showed that a control group imitated changes in movement kinematics and increased the level that they tracked the hand with their eyes, in the goal-less compared to goal-direction condition. In contrast, the ASD group exhibited more goal-directed eye movements, and failed to modulate the observed movement kinematics successfully in either condition. These results increase the evidence for impaired goal-less imitation in ASD, and suggest that there is a reliance on goal-directed strategies for imitation in ASD, even in the absence of visual goals.

Instructions to attend to an observed action increase imitation in autistic adults / Emma GOWEN in Autism, 24-3 (April 2020)

A total of 22 autistic and 22 non-autistic adults observed and then imitated videos of a hand producing sequences of movements that differed in vertical elevation while their hand and eye movements were recorded. Participants first performed a block of imitation trials with general instructions to imitate the action. They then performed a second block with explicit instructions to attend closely to the characteristics of the movement. Imitation was quantified according to how much participants modulated their movement between the different heights of the observed movements. In the general instruction condition, the autistic group modulated their movements significantly less compared to the non-autistic group. However, following instructions to attend to the movement, the autistic group showed equivalent imitation modulation to the non-autistic group. Eye movement recording showed that the autistic group spent significantly less time looking at the hand movement for both instruction conditions. These findings show that visual attention contributes to altered voluntary imitation in autistic individuals and have implications for therapies involving imitation as well as for autistic people's ability to understand the actions of others.

Investigating Visual–Tactile Interactions over Time and Space in Adults with Autism / Daniel POOLE in Journal of Autism and Developmental Disorders, 45-10 (October 2015)

Typically, the likelihood of interactions between the senses increases when information is temporally and spatially coincident. We explored visual–tactile interactions in adults with ASC for the first time in two experiments using low-level stimuli. Both participants with ASC and matched neurotypical controls only produced crossmodal interactions to near simultaneous stimuli, suggesting that temporal modulation is unaffected in the adult population. We also provide preliminary evidence that visual–tactile interactions may occur over greater spatial distances in participants with ASC, which merits further exploration.
