Abstract
Autism spectrum disorders (ASD) are
pervasive developmental disorders characterized by deficits in social,
communicative, and emotional behaviors. In addition to these hallmarks,
there is evidence for unusual sensory experiences.
Relative to visual and auditory
processing, less is known about chemosensory (smell and taste) processing in
ASD. Children and adults diagnosed with ASD self- report abnormalities in
sensory and perception areas. But using standard methods of assessing
olfactory function (i.e., ability to detect, discriminate or identify odors) no
clear pattern of sensory differences have emerged. Thus a thorough understanding of chemosensory
processing in ASD is lacking.
The primary tool for assessing
sensory functioning in ASD is the Sensory Profile (SP), a self-report tool; however, the SP was not designed to
examine the functioning of individual sensory systems, but rather to measure
global sensory processing. The items that address chemosensory processing
appear to be particularly insensitive to assess olfactory function. Recently, a
Sensory Functions in Typical and Atypical Development (SFTAD) Questionnaire
(Parma, personal communication) has been developed, specifically with chemosensory
processing in mind. This presentation will explore the differences between the
SP and the SFTAD questionnaire. We will report preliminary data collected
online from 62 members of the Carthage community. This is an on-going study
that should contribute to a better understanding of chemosensory processing in
ASD.
