These threats have the ability to influence group behaviour and can have an effect on individual or collective welfare. While evidence suggests that threat exposure can increase cooperation and collective action, there is also evidence that suggests that threats actually break down cooperation. Furthermore, peer punishment is generally seen as a method to maintain cooperation, though usually at the cost of wasted resources. The effects of a shared threat on social decision-making in groups and the impact of peer punishment will be examined in order to test whether the presence of a common threat renders the use of peer punishment obsolete. Individuals (N = 180) in groups of three were exposed to the threat of electric shocks. Heart rate and skin conductance were continuously measured while participants decided how much to contribute to a public good. Half of the participating groups also got the opportunity to deduct resources from another participant during feedback phases.Show less
