Abstract
Understanding the nature of olfactory abnormalities is crucial for optimal interventions in children with autism spectrum disorders (ASD). However, previous studies that have investigated odor identification in children with ASD have produced inconsistent results. The ability to correctly identify an odor relies heavily on visual inputs in the general population. We tested odor identification in eight children with ASD and eight age-matched children with typical development (TD). After confirming that all children were able to identify each odor without visual input, we measured odor identification under the visual-distractor condition. Odor identification was hindered by visual distractors for all children with ASD but was not affected in all children with TD. Our results improve understanding of odor identification in ASD.
