Abstract
Learning from the consequences of previous decisions is key to improving one's decision making over time. The Iowa Gambling Task (IGT) is a commonly used test of decision making from experience. The IGT involves repeated choices from among four simulated decks of cards, two of which are better overall and two are worse overall. Success on the IGT requires learning which choices result in better outcomes. The extent to which good performance on the IGT relies on accurate, explicit knowledge of the frequency and magnitude of choice outcomes from simulated decks of cards has been debated. By orienting our participants to the use of different learning strategies, we manipulated the information that they focused on as they received feedback. This allowed us to better understand how they acquired and used choice outcome knowledge to improve decision making over time. We found that the different learning strategies for task knowledge resulted in differences in decision making performance, and that certain strategies significantly improved decision making over time.
