Abstract

We investigate how stable individuals’ risk attitudes are with respect to changes in cognitive load. In a laboratory experiment using pairwise lottery choice and a within-subject design, we showthat putting subjects under load via a concurrent working-memory task significantly increases their risk aversion. Subjects made significantly faster choices under load. Regardless of load, they responded faster when choosing the less risky option in safe–risky trials, but not in risky–risky trials. We discuss how these findings relate to both dual-system and unitarysystem theories of decision making.We observe that predictions of both recent dual-system and drift–diffusion models of the decision-making process are confirmed by our data and argue for a convergence of these to-date separate strands of the literature.
