Abstract

Autism spectrum disorders (ASD) are characterized by atypical cognitive, social, emotional, and perceptual functioning. An increasing body of evidence suggests that patients with ASD exhibit atypical perceptual and information processing in the auditory, visual, and tactile domains. However, the detailed characteristics of this atypical sensory functioning have not been fully elucidated. This chapter provides a comprehensive review of recent research into sensory processing in individuals with ASD, using a range of neuropsychological and neurophysiological techniques. Electroencephalography studies have reported atypical electrophysiological findings during sensory processing of visual, auditory, and tactile stimulation in individuals with ASD. In addition, functional magnetic resonance imaging studies have begun to elucidate the neural areas underlying these characteristic differences in sensory functioning. Several approaches, including environmental design, and support for parents and teachers to understand and respond to atypical sensory characteristics associated with ASD have been developed. Increasing understanding of the neurobiological processes underlying sensory problems in patients with ASD will aid the development of new treatment approaches.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Children with ASD exhibit abnormal or atypical visual, tactile/oral, olfactory, and auditory sensory responses; the entire somatosensory system presents alterations in the generation and processing of information.

    “Children with ASD exhibit abnormal or atypical visual, tactile/oral, olfactory, and auditory sensory responses; the entire somatosensory system that provides information from the environment, and allows its interaction with it, presents alterations in the generation and processing of information [34].”

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.
