Abstract
To identify the causal role of the DLPFC in decision making, we used transcranial direct current stimulation (tDCS) to investigate the contribution of DLPFC to performance in an incentivized decision task where optimal decisions require Bayesian updating of beliefs. In this task, an impulsive reinforcement-based heuristic can either conflict or be aligned with Bayesian updating. Previous research showed that in case of conflict individuals rely on the faulty heuristic, hence committing many decision errors. Based on the involvement of the DLPFC in inhibitory control we hypothesized that tDCS of the DLPFC would influence individual’s use of the reinforcement heuristic in case of conflict. 364 participants (158 in the original study; 206 in the replication study) received the anodal or cathodal tDCS stimulation to the right, left DLPFC or sham. While we observed improved decision making in first-draw decisions following anodal stimulation to the right DLPFC, our study did not find evidence indicating that tDCS stimulation over the DLPFC affected inhibition of reinforcement.
期刊介绍：
The Journal aims to present research that will improve understanding of behavioral, in particular psychological, aspects of economic phenomena and processes. The Journal seeks to be a channel for the increased interest in using behavioral science methods for the study of economic behavior, and so to contribute to better solutions of societal problems, by stimulating new approaches and new theorizing about economic affairs. Economic psychology as a discipline studies the psychological mechanisms that underlie economic behavior. It deals with preferences, judgments, choices, economic interaction, and factors influencing these, as well as the consequences of judgements and decisions for economic processes and phenomena. This includes the impact of economic institutions upon human behavior and well-being. Studies in economic psychology may relate to different levels of aggregation, from the household and the individual consumer to the macro level of whole nations. Economic behavior in connection with inflation, unemployment, taxation, economic development, as well as consumer information and economic behavior in the market place are thus among the fields of interest. The journal also encourages submissions dealing with social interaction in economic contexts, like bargaining, negotiation, or group decision-making. The Journal of Economic Psychology contains: (a) novel reports of empirical (including: experimental) research on economic behavior; (b) replications studies; (c) assessments of the state of the art in economic psychology; (d) articles providing a theoretical perspective or a frame of reference for the study of economic behavior; (e) articles explaining the implications of theoretical developments for practical applications; (f) book reviews; (g) announcements of meetings, conferences and seminars.
