Decision making plays a key role in daily function, but little is known regarding how individuals with autism spectrum disorder ( ASD ) make decisions. The present studies examined decision making in persons with ASD using the I owa G ambling T ask ( IGT ), a computerized card game with the goal of earning money by deciding among decks of cards. To be successful, players need to figure out which decks are associated with winning and which are associated with losing money in the long run. Results of S tudy 1 indicated that participants with ASD made poorer decisions and showed slower learning of which decks earned more money compared with participants with typical development. Additionally, they made more frequent shifts between decks compared with participants with typical development. In S tudy 2, undergraduate students with typical development completed the IGT to examine whether instructing them to make frequent shifts between decks early in the IGT would negatively impact their decision making. Results of S tudy 2 suggested that when participants with typical development were required to make frequent shifts, they exhibited a slower rate of learning and poorer decision making, thus emulating participants with ASD in S tudy 1. The combined results suggest that the way that persons with ASD explore and attend to their environment may be related to poor decision making. Implications for cognitive learning styles are discussed. Autism Res 2015, 8: 105–114 . © 2014 International Society for Autism Research, Wiley Periodicals, Inc.
