We tested this hypothesis using a serial reaction time task in which participants learned to predict the locations of a repeating sequence of target locations. We conducted a large-sample online study with 61 autistic and 71 neurotypical adults. The autistic group had slower overall reaction times, but demonstrated sequence-specific learning equivalent to the neurotypical group, consistent with other findings of typical procedural memory in autism. The neurotypical group, however, made significantly more prediction-related errors early in the experiment when the stimuli changed from repeated sequences to random locations, suggesting certain limited behavioural differences in the learning or utilization of predictive relationships for autistic adults.

Interceptive abilities in autism spectrum disorder: Comparing naturalistic and virtual visuomotor tasks / Se-Woong PARK in Autism Research, 17-12 (December 2024)  

Public ISBD [article]  inAutism Research > 17-12 (December 2024) . - p.2514-2534 Titre : Interceptive abilities in autism spectrum disorder: Comparing naturalistic and virtual visuomotor tasks Type de document : Texte imprimé et/ou numérique Auteurs : Se-Woong PARK, Auteur ; Annie CARDINAUX, Auteur ; Dena CROZIER, Auteur ; Marta RUSSO, Auteur ; Sabrina BOND, Auteur ; Margaret KJELGAARD, Auteur ; Pawan SINHA, Auteur ; Dagmar STERNAD, Auteur Article en page(s) : p.2514-2534 Langues : Anglais (eng) Mots-clés : autism  interception  motor behavior  naturalistic environment  praxis  prediction  virtual environment Index. décimale : PER Périodiques Résumé : Abstract A growing body of research reveals that autistic individuals exhibit motor coordination challenges. Multiple theoretical frameworks propose that the seemingly disparate features of autism may arise from a common underlying process: a diminished ability to make predictions. Sensorimotor skills, such as catching a ball, critically rely on predicting the ball's trajectory as well as anticipatory coordination of the entire body. Here, we assessed four different naturalistic and virtual interception tasks with 31 neurotypical and 23 autistic children (ages 7?12). In a naturalistic setting, participants caught the ball either with their hands or a hand-held funnel with an enlarged catch area that also prevented the ball from bouncing off. A virtual setup reduced whole-body demands, as children only moved a paddle to catch or bounce a ball on a screen. Control tasks, involving rapid reaching to grasp a static object and quiet standing, which largely eliminated the requirements for prediction, were also tested. Results from all task variations demonstrated that autistic children completed fewer successful interceptions, suggesting that predictive requirements, inherent to all interception tasks, played a critical role. Effect sizes in the virtual tasks were smaller. Correlations of the task metrics with behavioral assessments rendered the strongest correlations with Praxis scores. The control tasks showed no differences between autistic and neurotypical children. These findings lend support to the emerging hypothesis that predictive challenges are present in autism. Further research with larger sample sizes will help identify to what extent these visuomotor differences may inform core domains of autism.

Rhythmic and interval-based temporal orienting in autism / Jonathan CANNON in Autism Research, 16-4 (April 2023)  

Public ISBD [article]  inAutism Research > 16-4 (April 2023) . - p.772-782 Titre : Rhythmic and interval-based temporal orienting in autism Type de document : Texte imprimé et/ou numérique Auteurs : Jonathan CANNON, Auteur ; Emelie ELDRACHER, Auteur ; Annie CARDINAUX, Auteur ; Fatima IRFAN, Auteur ; Lindsay BUNGERT, Auteur ; Cindy LI, Auteur ; Amanda O'BRIEN, Auteur ; Isaac TREVES, Auteur ; Sidney DIAMOND, Auteur ; Pawan SINHA, Auteur Article en page(s) : p.772-782 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Individuals with autism spectrum disorder (ASD) may show secondary sensory and cognitive characteristics, including differences in auditory processing, attention, and, according to a prominent hypothesis, the formulation and utilization of predictions. We explored the overlap of audition, attention, and prediction with an online auditory ''temporal orienting'' task in which participants utilized predictive timing cues (both rhythmic and interval-based) to improve their detection of faint sounds. We compared an autistic (n =?78) with a nonautistic (n =?83) group, controlling for nonverbal IQ, and used signal detection measures and reaction times to evaluate the effect of valid temporally predictive cues. We hypothesized that temporal orienting would be compromised in autism, but this was not supported by the data: the boost in performance induced by predictability was practically identical for the two groups, except for the small subset of the ASD group with co-occurring attention deficit hyperactivity disorder, who received less benefit from interval-based cueing. However, we found that the presence of a rhythm induced a significantly stronger bias toward reporting target detections in the ASD group at large, suggesting weakened response inhibition during rhythmic entrainment.
