Abstract

Olfactory adaptation is an important process that allows the individual to adjust to changes in the environment. This process has been proposed to be aberrant in individuals with autism spectrum disorders (ASD). However, few studies have examined olfactory adaptation in children with ASD. We examined olfactory adaptation in children with ASD and typically developing (TD) children using a pulse ejection system, which resolved problems associated with previous laboratory-based olfactory psychophysical studies. Nine children with ASD and nine TD children participated in this study and all participants completed the entire experiment. Using this system, we found that the TD group showed greater adaptation than the ASD group. Our results provide a better understanding of olfactory adaptation in children with ASD.
