Relationship Between Autism Spectrum Disorder Characteristics and Humor Appreciation in Typically Developing Individuals.

Extant research regarding humor appreciation in individuals with autism spectrum disorder has been equivocal. This study aims to clarify the relationship between the severity of autism spectrum disorder characteristics and humor appreciation in typically developing individuals. We hypothesized that the severity of autistic traits would have a U-shaped linear relationship with humor appreciation. Eighty typically developing undergraduates between the ages of 18 and 22 years ( Mage  = 20.20; SDage  = 1.08) were recruited for this study. They were asked to answer 24 statements, devised to measure humor appreciation, in response to a joke stimulus comprising 12 typically funny daily life occurrences (two statements per episode). The participants also responded to the Japanese version of the Autism-Spectrum Quotient. A significant U-shaped relationship was observed between the severity of autistic traits and appreciation of humor. A similar significant U-shaped relationship was seen between humor appreciation and the Autism-Spectrum Quotient subscales of attention switching, communication, and imagination. Humor appreciation showed no significant U-shaped relationship with the Autism-Spectrum Quotient subscales of social skills and local details. This study identified ways that autistic traits may influence how people appreciate humor. These findings are discussed in relation to cognitive processes underlying humor appreciation.
