Self-Reported Sensory Hypersensitivity Moderates Association between Tactile Psychophysical Performance and Autism-Related Traits in Neurotypical Adults
Peer reviewed Peer reviewed

Bryant, Lauren K.; Woynaroski, Tiffany G.; Wallace, Mark T.; Cascio, Carissa J. – Journal of Autism and Developmental Disorders, 2019
Atypical responses to tactile stimulation have been linked to core domains of dysfunction in individuals with autism spectrum disorder (ASD) and phenotypic traits associated with ASD in neurotypical individuals. We investigated (a) the extent to which two psychophysically derived measures of tactile sensitivity--detection threshold and dynamic…

Self-Reported Pleasantness Ratings and Examiner-Coded Defensiveness in Response to Touch in Children with ASD: Effects of Stimulus Material and Bodily Location
Peer reviewed Peer reviewed

Cascio, Carissa J.; Lorenzi, Jill; Baranek, Grace T. – Journal of Autism and Developmental Disorders, 2016
Tactile defensiveness, characterized by behavioral hyperresponsiveness and negative emotional responses to touch, is a common manifestation of aberrant sensory processing in autism spectrum disorders (ASD) and other developmental disabilities (DD). Variations in tactile defensiveness with the properties of the stimulus and the bodily site of…

The Rubber Hand Illusion in Children with Autism Spectrum Disorders: Delayed Influence of Combined Tactile and Visual Input on Proprioception
Peer reviewed Peer reviewed

Cascio, Carissa J.; Foss-Feig, Jennifer H.; Burnette, Courtney P.; Heacock, Jessica L.; Cosby, Akua A. – Autism: The International Journal of Research and Practice, 2012
In the rubber hand illusion, perceived hand ownership can be transferred to a rubber hand after synchronous visual and tactile stimulation. Perceived body ownership and self-other relation are foundational for development of self-awareness, imitation, and empathy, which are all affected in autism spectrum disorders (ASD). We examined the rubber…

Foss-Feig, Jennifer H.; Heacock, Jessica L.; Cascio, Carissa J. – Research in Autism Spectrum Disorders, 2012
Autism spectrum disorders (ASD) are often associated with aberrant responses to sensory stimuli, which are thought to contribute to the social, communication, and repetitive behavior deficits that define ASD. However, there are few studies that separate aberrant sensory responses by individual sensory modality to assess modality-specific…
