People with autism have trouble relating to others. Some researchers wanted to test whether people with autism are less able to process social rewards than monetary rewards. There were 20 individuals in the study, 10 with autism and 10 without. All 20 individuals undertook a learning task that involved 200 attempts. For each success, they were shown either a photo of a person smiling or a picture of a dollar, which meant they would be paid a dollar later. Researchers concluded that autistic adults are less able to process social rewards than non-autistic people.
