The Importance of the Lateral Prefrontal Cortex for Strategic Decision Making in the Prisoner’s Dilemma


Soutschek, Alexander; Sauter, Marian; Schubert, Torsten (2015). The Importance of the Lateral Prefrontal Cortex for Strategic Decision Making in the Prisoner’s Dilemma. Cognitive, Affective, & Behavioral Neuroscience, 15(4):854-860.

Abstract

Previous functional imaging studies investigating the neural basis of strategic decision making in the prisoner’s dilemma reported a correlation between cooperative behavior and dorsolateral prefrontal cortex (DLPFC) activity; however, the precise function of the DLPFC in establishing cooperation remains unclear so far. The present study investigated the causal role of the DLPFC in an iterative prisoner’s dilemma game with transcranial magnetic stimulation (TMS). We discovered that disrupting the DLPFC with TMS decreased cooperation rates in comparison to control conditions, with this effect being most pronounced when the partner had defected previously. Thus, the current results suggest that the DLPFC contributes to strategic decision making in the prisoner’s dilemma game.
