Cooperative behaviour in a prisoners dilemma : a terror management perspective

This paper examines the terror management function of cooperative behaviour within a single-play Prisoner’s Dilemma (PD). Using 312 introductory psychology students, mortality salience significantly increased the cooperative behaviour of prosocial participants, while there was a non-significant difference in cooperative behaviour for individualistic and competitive participants. Changes in cooperative behaviour were not influenced by the ingroup or outgroup status of the other player. These findings identify cooperative behaviour for prosocials as an important behaviour that serves a terrormanagement function.
