Toward understanding everyday decision making by adults across the autism spectrum

Abstract

We focus on the everyday decision making challenges faced by high functioning adults across the Autism Spectrum using both between- andwithin-group comparisons. We usedMturk, backed by a combination of recruiting and screening procedures, to recruit large samples using an online survey. The main differences between groups were: greater relationship problems at home, school and work for the ASD group compared to the control group; greater difficulty in a variety of everyday decisions and the negative consequences of their decisions; greater aversion to social risks; lower levels of Rational Ability; and greater personal endorsement of socially undesirable acts. Poorer decision outcomes within the ASD group were predicted by lower levels of Rational Ability and higher personal endorsement of socially undesirable acts. Some of the same predictor-outcome relations were found within the Control group. These results illustrate how the study of unique groups can increase our overall understanding of individual differences in decision making within the general population, and the need to include both between-group and within-group analyses.
