  • playing violent video games increases intergroup bias
    Personality and Social Psychology Bulletin, 2014
    Co-Authors: Tobias Greitemeyer
    Abstract:

    Previous research has shown how, why, and for whom violent video game play is related to aggression and aggression-related variables. In contrast, less is known about whether some individuals are more likely than others to be the target of increased aggression after violent video game play. The present research examined the idea that the effects of violent video game play are stronger when the target is a Member of an outgroup rather than an Ingroup. In fact, a correlational study revealed that violent video game exposure was positively related to ethnocentrism. This relation remained significant when controlling for trait aggression. Providing causal evidence, an experimental study showed that playing a violent video game increased aggressive behavior, and that this effect was more pronounced when the target was an outgroup rather than an Ingroup Member. Possible mediating mechanisms are discussed.

  • group identity and social preferences
    The American Economic Review, 2009
    Co-Authors: Yan Chen
    Abstract:

    We present a laboratory experiment that measures the effects of induced group identity on social preferences. We find that when participants are matched with an Ingroup Member, they show a 47 percent increase in charity concerns and a 93 percent decrease in envy. Likewise, participants are 19 percent more likely to reward an Ingroup match for good behavior, but 13 percent less likely to punish an Ingroup match for misbehavior. Furthermore, participants are significantly more likely to choose social-welfare-maximizing actions when matched with an Ingroup Member. All results are consistent with the hypothesis that participants are more altruistic toward an Ingroup match. (

  • collective synchrony increases prosociality towards non performers and outgroup Members
    British Journal of Social Psychology, 2016
    Co-Authors: Paul Reddish, Eddie M W Tong, Jonathan Jong, Jonathan Lanman, Harvey Whitehouse
    Abstract:

    Previous research has found that behavioural synchrony between people leads to greater prosocial tendencies towards co-performers. In this study, we investigated the scope of this prosocial effect: does it extend beyond the performance group to an extended Ingroup (extended parochial prosociality) or even to other people in general (generalized prosociality)? Participants performed a simple rhythmic movement either in time (synchrony condition) or out of time (asynchrony condition) with each other. Before and during the rhythmic movement, participants were exposed to a prime that made salient an extended Ingroup identity. After the task, half of the participants had the opportunity to help an extended Ingroup Member; the other half had the opportunity to help an outgroup Member. We found a main effect of our synchrony manipulation across both help targets suggesting that the prosocial effects of synchrony extend to non-performers. Furthermore, there was a significantly higher proportion of participants willing to help an outgroup Member after moving collectively in synchrony. This study shows that under certain intergroup contexts synchrony can lead to generalized prosociality with performers displaying greater prosociality even towards outgroup Members.

  • the loyal Member effect on the preference for Ingroup Members who engage in exclusive relations with the Ingroup
    Developmental Psychology, 2007
    Co-Authors: Luigi Castelli, Leyla De Amicis, Steven J Sherman
    Abstract:

    The goal of this article was to investigate an indirect form of intergroup differentiation in children in the context of racial attitudes: the preference for Ingroup Members who interact positively with other Ingroup Members rather than with outgroup Members. Study 1 confirmed this general hypothesis with preschool and 1st-grade children, demonstrating that respondents preferred the Ingroup Member who played only with other Ingroup Members, evaluated this child more positively, and felt more similar to him or her. Studies 2 and 3 tested the boundary conditions of the phenomenon. Study 4 analyzed developmental changes demonstrating that the effect is no longer observed among 9- to 11-year-old children. Overall, these studies suggest that engaging in positive interactions with the outgroup might have its costs in terms of a relative devaluation and rejection by one's peers. Results are discussed by stressing the importance of intragroup processes for the regulation of intergroup relations among very young children.
