Don’t Bet on it! Wagering as a Measure of Awareness in Decision Making under Uncertainty

David R. Shanks and Emmanouil Konstantinidis


Can our decisions be guided by unconscious or implicit influences? According to the somatic marker hypothesis, emotion-based signals can guide our decisions in uncertain environments outside awareness. Post-decision wagering, in which participants make wagers on the outcomes of their decisions, has been recently proposed as an objective and sensitive measure of conscious content. We have employed variations of a classic decision-making paradigm, the Iowa Gambling Task, in combination with wagering in order to investigate the role played by unconscious influences. We examined the validity of post-decision wagering by comparing it with alternative measures of conscious knowledge, specifically confidence ratings and quantitative questions. Consistent with a putative role for unconscious influences, we observed a lag between choice accuracy and the onset of advantageous wagering. However, the lag was eliminated by a change in the wagering payoff matrix and by a switch from a binary wager response to either a binary or a 4-point confidence response, and wagering underestimated awareness compared to explicit quantitative questions. Our results demonstrate the insensitivity of post-decision wagering as a direct measure of conscious knowledge and challenge the claim that implicit processes influence decision-making under uncertainty.
