Abstract

The integration of prior expectations, sensory information, and environmental volatility is proposed to be atypical in Autism Spectrum Disorder, yet few studies have tested these predictive processes in active movement tasks. To address this gap in the research, we used an immersive virtual-reality racquetball paradigm to explore how visual sampling behaviours and movement kinematics are adjusted in relation to unexpected, uncertain, and volatile changes in environmental statistics. We found that prior expectations concerning ball ‘bounciness’ affected sensorimotor control in both autistic and neurotypical participants, with all individuals using prediction-driven gaze strategies to track the virtual ball. However, autistic participants showed substantial differences in visuomotor behaviour when environmental conditions were more volatile. Specifically, uncertainty-related performance difficulties in these conditions were accompanied by atypical movement kinematics and visual sampling responses. Results support proposals that autistic people overestimate the volatility of sensory environments, and suggest that context-sensitive differences in active inference could explain a range of movement-related difficulties in autism.

  • Individuals with autism spectrum disorder could learn priors similarly to healthy controls, although they showed less flexibility in adjusting precision in volatile contexts.

    “In addition, they could learn priors similarly to HC, although they showed less flexibility in adjusting precision in volatile contexts (i.e., an environment that is constantly changing) (Arthur et al., 2021).”

    From Predictive coding in neuropsychiatric disorders: a systematic transdiagnostic review. (2025) · cites this paper as Arthur et al., 2021

    The Discussion (page unavailable) reports that autistic participants used a prediction-driven visual strategy similarly to neurotypical participants, supporting comparable use of prior information, though it does not directly establish that both groups learned priors equally. It also reports atypical behaviours associated with volatility, but says the groups appeared to adjust visual sampling and motor kinematics comparably as environmental stability changed. Thus, the claim of less flexible precision adjustment in volatile contexts overstates the findings. (LLM, conf=0.84)

  • Arthur et al. [43] report data from a virtual reality tennis task in which participants were required to intercept a ball that bounced in front of them.

    “Arthur et al. [43] report data from a virtual reality (VR) tennis task in which participants were required to intercept a ball that bounced in front of them.”

    From Testing predictive coding theories of autism spectrum disorder using models of active inference (2023) · cites this paper as Arthur et al. [43]

    The Results describe a VR task in which participants intercepted a ball that bounced toward them. However, the Introduction and Methods identify it as a virtual racquetball task, not a tennis task; the Methods say only that the virtual ball resembled a tennis ball. Page numbers are not provided in our copy. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
