Question

Quizplus · Accepted Answer

The brain region that is activated when someone chooses to cooperate in the prisoner's dilemma game is the striatum, which is also activated when someone experiences positive outcomes (such as looking at pictures of tropical vacations) or receives a reward (such as tasting something sweet). Therefore, choice D is the best answer as both option A and B involve positive outcomes that activate the striatum. Option C (looking at photos of outgroup members) does not activate the striatum and is thus an incorrect option.
