Objectives: Humor is essential to social relationships. Its use and understanding appear to be impaired in people with Autism Spectrum Disorder (ASD). The main objective was to review the existing literature on the detection, understanding and use of humor in persons with ASD. The secondary objective involved exploring assessment scales and specific intervention tools.
Methods: A systematic review of the literature was carried out on all available French and English scientific papers about humor - including irony - in persons with ASD up to November 2021. We extracted 552 references and included 43 articles from six databases.
Results: Studies suggest that those with ASD can detect audiovisual and written humor. Understanding humor was impaired in writing and when using pure auditory stimuli and non-verbal cartoons. For irony, the results indicated a lower detection of quality and less understanding in speaking but not in writing. Regarding its use, in terms of expression, people with ASD use benevolent humor less often and do not consider humor as a key source of satisfaction with life, as opposed to the control group.
Conclusions: It appears that it would be worthwhile to develop standardized humor detection and assessment tools specific to persons with ASD. Practical strategies that focus on humor ability could be worth developing, either individually or in groups.
