 In children with autism There was a study done involving twenty six children with autism and fifteen children with other learning disabilities, in which an adult displayed some form of emotion to study how the children respond. They focused on attention, hedonic tone, latency to changes in tone and an emotional contagion summery was made. Studies showed correlations between measures of joint attention, emotional contagion, and the severity of autism. Results showed that children with autism did not demonstrate changes in affect, however their responses occurred much less than in comparison groups .
