We study whether differences in the propensity of actual leaders to enforce cooperation by punishing group members as a third party in a social dilemma game can explain the variation in the performance of these groups in managing their forest commons. Our results highlight the importance of leaders in collective action, emphasizing the significant role of leaders’ other- regarding motives for cooperation outcomes.

Brain-wide synchronization networks subserve selective attention

Selective attention entails the selective routing of relevant information between brain areas. I will demonstrate that this selective routing is subserved by the selective synchronization between those brain regions that process relevant information. In particular, higher level visual cortex that can respond to input from different parts of primary visual cortex, synchronizes selectively to those parts that represent a relevant stimulus, even if other parts are activated by irrelevant stimuli.
