Opposite effects of feedback contingency on the process of risky decisions-making

The main aim of this study was to look into the effect of feedback contingency on decision making in complex risky situations, using a driving context. Participants had to decide braking or not in a set of risky traffic situations. After the response, a negative non-contingent or contingent feedback was used. The results highlight the importance of feedback contingency upon safer decision making in risky contexts, as they showed how a contingent feedback led to faster and safer responses than a control group without any feedback; whereas a non-contingent one gives rise to slower responses and, more importantly, an enhanced risk-taking behavior that could be the cause of undesirable effects on road safety. The feedback effect was even more evident in the appearance of an opposite response bias as a function of contingency and enhanced by learning. These results accord with the theoretical accounts based upon the feedback influence on the threshold level of decision making. Moreover, the effects of feedback may be explained by new proposals focusing on the importance of attentional factors as well as of the mental models people build to react in complex risky scenarios, as a product of feedback and learning. Finally, this research may increase our understanding of the role of feedback in the process of learning safer behavior in complex risky situations.
