An Exploratory Study on the Association between Atypical Behavioral Responses to Tickling and Autistic Traits in Japanese Children.

Abstract

Although play is an essential occupation for children, parents of children with autistic traits tend to struggle with play-based interpersonal interaction with them. Tickling play appears to be one of the most interpersonal forms of play because nobody can tickle themselves. However, atypical tactile processing (e.g. tactile sensitivity) has been reported in children with autistic traits, who may exhibit atypical behavioral responses during tickling play. Our aim was to investigate the association between autistic traits and behavioral responses during parent-child tickling play in Japanese young children. We recorded tickling interaction between children and their parents using behavior coding with six behavioral items. Autistic traits and tactile sensitivity were measured using parent-reported questionnaires. Results showed two behavioral responses were significantly associated with autistic traits in all children: "approach with positive emotional response" and "no response" were negatively and positively correlated with autistic traits, respectively. This exploratory study suggests that behavioral responses during tickling play may be associated with autistic traits.
