In individuals with typical development, the corpus callosum is known to undergo a protracted development from childhood through young adulthood. However, no study has longitudinally examined the developmental trajectory of corpus callosum in autism past early childhood.

Brainstem White Matter Predicts Individual Differences in Manual Motor Difficulties and Symptom Severity in Autism / Brittany G. TRAVERS in Journal of Autism and Developmental Disorders, 45-9 (September 2015) 

Public ISBD [article]  in Journal of Autism and Developmental Disorders > 45-9 (September 2015) . - p.3030-3040 Titre : Brainstem White Matter Predicts Individual Differences in Manual Motor Difficulties and Symptom Severity in Autism Type de document : texte imprimé Auteurs : Brittany G.

LAINHART, Auteur Article en page(s) : p.3030-3040 Langues : Anglais (eng) Mots-clés : Autism  Motor  Diffusion tensor imaging  Brainstem  Grip strength  Finger tapping Index. décimale : PER Périodiques Résumé : Mounting evidence suggests that poorer motor skills may be related to more severe autism symptoms. This study investigated if atypical white matter microstructure in the brain mediated the relationship between motor skills and ASD symptom severity. Sixty-seven males with ASD and 42 males with typical development (5–33 years old) completed a diffusion tensor imaging scan and measures of grip strength, finger tapping, and autism symptom severity. Within the ASD group, weaker grip strength predicted more severe autism symptoms. Fractional anisotropy of the brainstem’s corticospinal tract predicted both grip strength and autism symptom severity and mediated the relationship between the two. These findings suggest that brainstem white matter may contribute to autism symptoms and grip strength in ASD.

Decision-Making Skills in ASD: Performance on the Iowa Gambling Task / Joanna L. MUSSEY in Autism Research, 8-1 (February 2015) 

Public ISBD [article]  in Autism Research > 8-1 (February 2015) . - p.105-114 Titre : Decision-Making Skills in ASD: Performance on the Iowa Gambling Task Type de document : texte imprimé Auteurs : Joanna L. MUSSEY, Auteur ; Brittany G. TRAVERS, Auteur ; Laura Grofer KLINGER, Auteur ; Mark R. KLINGER, Auteur Article en page(s) : p.105-114 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  decision making  Iowa Gambling Task  implicit learning Index. décimale : PER Périodiques Résumé : Decision making plays a key role in daily function, but little is known regarding how individuals with autism spectrum disorder (ASD) make decisions. The present studies examined decision making in persons with ASD using the Iowa Gambling Task (IGT), a computerized card game with the goal of earning money by deciding among decks of cards. To be successful, players need to figure out which decks are associated with winning and which are associated with losing money in the long run. Results of Study 1 indicated that participants with ASD made poorer decisions and showed slower learning of which decks earned more money compared with participants with typical development. Additionally, they made more frequent shifts between decks compared with participants with typical development. In Study 2, undergraduate students with typical development completed the IGT to examine whether instructing them to make frequent shifts between decks early in the IGT would negatively impact their decision making. Results of Study 2 suggested that when participants with typical development were required to make frequent shifts, they exhibited a slower rate of learning and poorer decision making, thus emulating participants with ASD in Study 1. The combined results suggest that the way that persons with ASD explore and attend to their environment may be related to poor decision making. Implications for cognitive learning styles are discussed. Autism Res 2015, 8: 105–114.

Difficulties with multi-sensory fear conditioning in individuals with autism spectrum disorder / Patrick S. POWELL in Research in Autism Spectrum Disorders, 25 (May 2016) 

Public ISBD [article]  in Research in Autism Spectrum Disorders > 25 (May 2016) . - p.137-146 Titre : Difficulties with multi-sensory fear conditioning in individuals with autism spectrum disorder Type de document : texte imprimé Auteurs : Patrick S.

KLINGER, Auteur Article en page(s) : p.137-146 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Conditioning  Associative learning  Emotion learning Index. décimale : PER Périodiques Résumé : AbstractBackground Classical conditioning represents a fundamental aspect of learning, allowing us to infer relationships between coinciding events in our environment. However, recent evidence has suggested this fundamental form of learning may be compromised in individuals with autism spectrum disorder (ASD). The present study utilized galvanic skin responses to examine classical conditioning in individuals with ASD across sensory modalities. Method Fifteen individuals diagnosed with ASD and 16 age-, gender-, and IQ-matched individuals with typical development participated in this study. Using a differential fear conditioning paradigm, participants were presented with a series of colors and sounds. A subset of these colors and sounds was paired with an aversive loud noise. Learning the contingency between the color and/or sound and the aversive noise was measured by changes in skin conductance. Following this task, an explicit-knowledge test probed participant’s awareness of these contingencies. Results Results indicated that individuals with ASD had a general impairment in fear conditioning compared to individuals with typical development. Additionally, participants with ASD who showed greater explicit awareness of the contingencies showed conditioned responses more similar to participants with typical development. Conclusions Implications for theories of the neurobiological mechanisms associated with learning and social impairments in ASD are discussed.
