This study aimed to address both these issues by developing the Social Reward Questionnaire (SRQ), a measure of(More)
According to the social motivation hypothesis of autism, individuals with high levels of autistic traits experience reduced levels of reward from social interactions. However, empirical evidence to date has been mixed, with some studies reporting lower levels of social reward in individuals with Autism Spectrum Disorder (ASD), and others finding no(More)
