Individuals With Autism Have No Detectable Deficit in Neural Markers of Prediction Error When Presented With Auditory Rhythms of Varied Temporal Complexity / Emily J. KNIGHT in Autism Research, 13-12 (December 2020)  

Public ISBD [article]  inAutism Research > 13-12 (December 2020) . - p.2058-2072 Titre : Individuals With Autism Have No Detectable Deficit in Neural Markers of Prediction Error When Presented With Auditory Rhythms of Varied Temporal Complexity Type de document : texte imprimé Auteurs : Emily J. KNIGHT, Auteur ; Leona A. OAKES, Auteur ; Susan L. HYMAN, Auteur ; Edward G. FREEDMAN, Auteur ; John J. FOXE, Auteur Article en page(s) : p.2058-2072 Langues : Anglais (eng) Mots-clés : auditory perceptual disorders  autism spectrum disorder  communication disorders  electroencephalography  evoked potentials, auditory  mismatch negativity Index. décimale : PER Périodiques Résumé : The brain's ability to encode temporal patterns and predict upcoming events is critical for speech perception and other aspects of social communication. Deficits in predictive coding may contribute to difficulties with social communication and overreliance on repetitive predictable environments in individuals with autism spectrum disorder (ASD). Using a mismatch negativity (MMN) task involving rhythmic tone sequences of varying complexity, we tested the hypotheses that (1) individuals with ASD have reduced MMN response to auditory stimuli that deviate in presentation timing from expected patterns, particularly as pattern complexity increases and (2) amplitude of MMN signal is inversely correlated with level of impairment in social communication and repetitive behaviors. Electroencephalography was acquired as individuals (age 6-21 years) listened to repeated five-rhythm tones that varied in the Shannon entropy of the rhythm across three conditions (zero, medium-1 bit, and high-2 bit entropy). The majority of the tones conformed to the established rhythm (standard tones); occasionally the fourth tone was temporally shifted relative to its expected time of occurrence (deviant tones). Social communication and repetitive behaviors were measured using the Social Responsiveness Scale and Repetitive Behavior Scale-Revised. Both neurotypical controls (n = 19) and individuals with ASD (n = 21) show stepwise decreases in MMN as a function of increasing entropy. Contrary to the result forecasted by a predictive coding hypothesis, individuals with ASD do not differ from controls in these neural mechanisms of prediction error to auditory rhythms of varied temporal complexity, and there is no relationship between these signals and social communication or repetitive behavior measures. LAY SUMMARY: We tested the idea that the brain's ability to use previous experience to influence processing of sounds is weaker in individuals with autism spectrum disorder (ASD) than in neurotypical individuals. We found no difference between individuals with ASD and neurotypical controls in brain wave responses to sounds that occurred earlier than expected in either simple or complex rhythms. There was also no relationship between these brain waves and social communication or repetitive behavior scores.

Relationship Among Anxiety, Depression, and Family Impact in Adolescents With Autism Spectrum Disorder and Average-Range IQ / Suzannah IADAROLA in Focus on Autism and Other Developmental Disabilities, 33-3 (September 2018)

OAKES, Auteur ; Wendy SHIH, Auteur ; Michelle DEAN, Auteur ; Tristram SMITH, Auteur ; Felice ORLICH, Auteur Article en page(s) : p.171-181 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Little is known about how internalizing symptoms in autism spectrum disorder (ASD) affect family outcomes, despite the high rates of internalizing disorders in ASD and the dynamic relationships among child, parent, and family variables. We evaluated the predictive value of internalizing symptoms in 69 adolescents with ASD and average-range cognitive abilities on family impact. In addition, we examined the correspondence between parent and child symptom ratings. Results indicated that internalizing symptoms predict family impact above IQ and externalizing symptoms. Depression (but not anxiety) predicted more positive family functioning, and parents rated more internalizing symptoms than adolescents. The results are contrary to our initial predictions, and we offer several explanations for this difference. Differences between parent and child ratings of internalizing symptoms are also explored.
