Autistic Adults Show Intact Learning on a Visuospatial Serial Reaction Time Task / Isaac N. TREVES in Journal of Autism and Developmental Disorders, 54-4 (April 2024)

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.

Autonomic and Electrophysiological Evidence for Reduced Auditory Habituation in Autism / Tapan K. GANDHI in Journal of Autism and Developmental Disorders, 51-7 (July 2021)

What aspects of sensory processing are affected in autism? Although sensory processing can be studied along multiple dimensions, two of the most basic ones involve examining instantaneous sensory responses and how the responses change over time. These correspond to the dimensions of 'sensitivity' and 'habituation'. Results thus far have indicated that autistic individuals do not differ systematically from controls in sensory acuity/sensitivity. However, data from studies of habituation have been equivocal. We have studied habituation in autism using two measures: galvanic skin response (GSR) and magneto-encephalography (MEG). We report data from two independent studies. The first study, was conducted with 13 autistic and 13 age-matched neurotypical young adults and used GSR to assess response to an extended metronomic sequence. The second study involved 24 participants (12 with an ASD diagnosis), different from those in study 1, spanning the pre-adolescent to young adult age range, and used MEG. Both studies reveal consistent patterns of reduced habituation in autistic participants. These results suggest that autism, through mechanisms that are yet to be elucidated, compromises a fundamental aspect of sensory processing, at least in the auditory domain. We discuss the implications for understanding sensory hypersensitivities, a hallmark phenotypic feature of autism, recently proposed theoretical accounts, and potential relevance for early detection of risk for autism.

Intact Visual Correlation Detection in Autistic Adults / Lukas VOGELSANG in Autism Research, 19-9 (September 2026)

NELSON, Auteur ; Pawan SINHA, Auteur Article en page(s) : p. e70339 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  coincidence detection  sensory correlations  temporal processing  visual perception Index. décimale : PER Périodiques Résumé : ABSTRACT The ability to detect recurring temporal co-occurrence, or temporal correlation, of sensory events is fundamental for organizing perceptual input into coherent representations. Although past work has revealed differences across several aspects of temporal processing in autism, it is unknown whether autistic and non-autistic individuals differ in the key computation of correlation detection. Here, we examined this question in the visual domain using an online task. A total of 143 age- and sex-matched adults (73 autistic, 70 non-autistic) viewed sequences in which three visual elements stochastically alternated between bright and dark states. Two of these were disks, and the third was a surrounding annulus. Participants indicated which of the two disks co-occurred more reliably with the annulus. Accuracy increased systematically with correlation strength in both groups, but there were no significant group differences and no negative association between performance and autistic trait scores when controlling for nonverbal IQ. These findings suggest that visual correlation detection, under the conditions tested here, is preserved in autistic adults. This points to a key aspect of temporal processing in autism that may provide a stable foundation for perceptual organization even amid challenges reported in other timing-related domains, such as higher-level temporal prediction. These results set the stage for future research to identify the mechanisms underlying both preserved and divergent temporal processes, and to translate these findings into evidence-based support that builds on the observed strengths of autistic individuals.

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

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.
