Studies on grandparental investment have revealed that mothers' fathers are emotionally closer to their grandchildren than are fathers' mothers. In the current study, it was hypothesized that this difference is caused by the fact that fathers' mothers often have the potential to invest in genetically more certain kin (children through their daughters). To(More)
Being human implies a particular moral status: having moral value, agency, and responsibility. However, people are not seen as equally human. Across two studies, we examine the consequences that subtle variations in the perceived humanness of actors or groups have for their perceived moral status. Drawing on Haslam's two-dimensional model of humanness and(More)
Reactions to moral transgressions are subject to influence at both the cultural and individual levels. Transgressions against an individual's rights or against social conventions of hierarchy may elicit different reactions in individualistic and collectivistic cultures. In the current study, affective and behavioural reactions to transgressions of autonomy(More)
When clinicians facilitate and patients make decisions about predictive genetic testing, they often base their choices on the predicted emotional consequences of positive and negative test results. Research from psychology and decision making suggests that such predictions may often be biased. Work on affective forecasting-predicting one's future emotional(More)
The present experiment tested the hypothesis that discrepancies in processing fluency influence the perceived wrongness of moral violations. Participants were presented with numerous moral violations in easy or difficult to read font. For some violations experienced perceptual fluency was consistent with the fluency associated with previous violations,(More)
While it is generally acknowledged that another person's presence can influence how we behave within our environment, our understanding of the mechanisms underlying this influence is limited. Three experiments investigated the effect of social presence on the lateral distribution of spatial attention. Shifts in spatial attention were measured using line(More)
Four studies investigated whether people tend to see ingroup flaws as part of human nature (HN) to a greater degree than outgroup flaws. In Study 1, people preferentially ascribed high HN flaws to their ingroup relative to two outgroups. Study 2 demonstrated that flaws were rated higher on HN when attributed to the ingroup than when attributed to an(More)
Although a great deal of research has investigated the relationship between emotions and action orientations, most studies to date have used variable-centered techniques to identify the best emotion predictor(s) of a particular action. Given that people frequently report multiple or blended emotions, a profitable area of research may be to adopt(More)
