This study examines whether the impact of offline identities on computer-mediated communication is stable across different social contexts or whether it depends on which identity aspect is salient. Field experiments with 206 teenagers tested the influence of gendered, ethnic, youth and...

Using a laboratory experiment with minimal groups, we examined the extent to which the threats of costly punishments affect in-group favouritism behaviour. We studied three types of punishment separately: in-group, out-group, and third-party punishments. In line with previous studies, the...

Aligned with research in the social capital and general health literature, a large body of evidence shows that older people who are more socially active have better cognitive integrity and are less vulnerable to cognitive decline. The present research addresses the question of whether the type...

In the present paper we uncover a novel mechanism through which a minority can gain a disproportionate power in a perfectly functioning democracy. In our model, a government elected by majority within a two party democracy, decides on a unique redistributive instrument, the tax rate. We show...

In order to improve the understanding of media violence effects, it is crucial to extend knowledge about factors that threaten the validity of such effects in empirical research. Research artifacts can be expected when participants are (a) aware of a scientist’s hypothesis, (b) motivated to...

Does culture matter in decision-making? Existing literature largely assumes that the cognitive processes that inform decision-making are universally applicable, while only very few studies indicate that cultural norms and values shape cognitive processes. Using survey based quasi-experimental...

While Europe as a superordinate social category has the capability of solidarity between its subcategories (<i>i.e.</i>, nations), negative emotions and behaviors...

A frequently observed phenomenon in professional sports is apparent underpricing of tickets. The concept of social identity may explain this pricing behavior without giving up the assumption of profit-maximizing behavior. Repeated match attendance increases spectators' identification with the...
