“…The enhanced proprioceptive performance of individuals with ASD-like traits in the present study (and in the ASD group in our previous rubber-hand illusion study ;Paton et al, 2012) conflicts somewhat with a recent study examining limb proprioception in ASD outside of the context of sensory illusions (Fuentes, Mostofsky, & Bastian, 2011). In particular, no differences were found in this latter study in the accuracy and precision of proprioceptive estimates regarding arm position between individuals with ASD and healthy controls.…”

Movement under uncertainty: The effects of the rubber-hand illusion vary along the nonclinical autism spectrum

et al. 2013

Recent research has begun to investigate sensory processing in relation to nonclinical variation in traits associated with the autism spectrum disorders (ASD). We propose that existing accounts of autistic perception can be augmented by considering a role for individual differences in top-down expectations for the precision of sensory input, related to the processing of state-dependent levels of uncertainty. We therefore examined ASD-like traits in relation to the rubber-hand illusion: an experimental paradigm that typically elicits crossmodal integration of visual, tactile, and proprioceptive information in an unusual illusory context. Individuals with higher ASD-like traits showed reduced effects of the rubber-hand illusion on perceived arm position and reach-to-grasp movements, compared to individuals with lower ASDlike traits. These differences occurred despite both groups reporting the typical subjective experience of the illusion concerning visuotactile integration and ownership for the rubber hand. Together these results suggest that the integration of proprioceptive information with cues for arm position derived from the illusory context differs between individuals partly in relation to traits associated with ASD.We suggest that the observed differences in sensory integration can be best explained in terms of differing expectations regarding the precision of sensory estimates in contexts that suggest uncertainty.

“…Even though we cannot fully rule out this possibility, studies assessing vestibular function in ASD suggest intact vestibuloocular reflex function in studies assessing children (Goldberg, Landa, Lasker, Cooper, & Zee, 2000) and children and adults with ASD (Furman, Osorio, & Minshew, 2015). This evidence is in line with the intact nature of sensory information in ASD, including lowlevel visual information (Bertone et al, 2005;Pellicano et al, 2005;Pellicano & Gibson, 2008) and proprioceptive acuity (Fuentes et al, 2011).…”

“…For example, Pellicano and Gibson (2008) assessed integrity of dorsal stream visual processing in ASD and showed that children with ASD exhibited intact lower-level but impaired higher-level dorsal stream functioning. In a similar vein, proprioception was assessed in adolescents with ASD and Typically Developing (TD) controls using proprioceptive matching tasks (Fuentes, Mostofsky, & Bastian, 2011). In this study, although ASD participants were impaired in general sensory and motor performance, their proprioceptive abilities were not different from typically developing adolescents'.…”

We investigated the nature of sensory integration deficits in postural control of young adults with ASD. Postural control was assessed in a fixed environment, and in three environments in which sensory information about body sway from visual, proprioceptive or both channels was inaccurate. Furthermore, two levels of inaccurate information were used within each channel (gain 1 and 1.6). ASD participants showed greater postural sway when information from both channels was inaccurate. In addition, control participants' ellipse area at gain 1.6 was identical to ASD participants' at gain 1, reflecting hyper-reactivity in ASD. Our results provide evidence for hyperreactivity in posture-related sensory information, which reflects a general, rather than channel-specific sensory integration impairment in ASD.

“…B 282: 20141557 illusion in movement. While there is evidence that proprioceptive estimates in non-illusory conditions are no more accurate or precise in ASD than in controls [46], this study differs in incorporating an uncertain context in which conflict between cues for arm position derived from the illusion and proprioceptive input during illusion induction may induce an expectation for low precision in the sensory input. That is, sensorimotor input can normally be interpreted unequivocally under long-held, very stable expectations about body-image, body-schema and bodily self-awareness, but the RHI challenges these expectations and throws doubt on the sensory input.…”

Context sensitivity in action decreases along the autism spectrum: a predictive processing perspective

et al. 2015

Recent predictive processing accounts of perception and action point towards a key challenge for the nervous system in dynamically optimizing the balance between incoming sensory information and existing expectations regarding the state of the environment. Here, we report differences in the influence of the preceding sensory context on motor function, varying with respect to both clinical and subclinical features of autism spectrum disorder (ASD). Reach-to-grasp movements were recorded subsequent to an inactive period in which illusory ownership of a prosthetic limb was induced. We analysed the sub-components of reach trajectories derived using a minimum-jerk fitting procedure. Non-clinical adults low in autistic features showed disrupted movement execution following the illusion compared to a control condition. By contrast, individuals higher in autistic features (both those with ASD and non-clinical individuals high in autistic traits) showed reduced sensitivity to the presence of the illusion in their reaching movements while still exhibiting the typical perceptual effects of the illusion. Clinical individuals were distinct from non-clinical individuals scoring high in autistic features, however, in the early stages of movement. These results suggest that the influence of high-level representations of the environment differs between individuals, contributing to clinical and subclinical differences in motor performance that manifest in a contextual manner. As high-level representations of context help to explain fluctuations in sensory input over relatively longer time scales, more circumscribed sensitivity to prior or contextual information in autistic sensory processing could contribute more generally to reduced social comprehension, sensory impairments and a stronger desire for predictability and routine.
