Building upon the social emotion model (Smith, 1999), we examined the combined impact of categorization context and social identification on emotional reactions and behavioural tendencies of people confronted with the victims of harmful behaviour. Depending on conditions, participants were led to categorize the victims and themselves in the same common group or in two distinct subgroups of the ...

In social environments, decisions not only determine rewards for oneself but also for others. However, individual differences in pro-social behaviors have been typically studied through self-report. We developed a decision-making paradigm in which participants chose from card decks with differing rewards for themselves and charity; some decks gave similar rewards to both, while others gave high...

Antisocial individuals are characterized to display self-determined and inconsiderate behavior during social interaction. Furthermore, recognition deficits regarding fearful facial expressions have been observed in antisocial populations. These observations give rise to the question whether or not antisocial behavioral tendencies are associated with deficits in basic processing of social cues. ...

There is little that more graphically indicates the normative character of much social science than its handling of misbehaviour. There is a great deal of evidence, particularly gathered from ethnographic research, indicating that misbehaviour at work is prevalent at all levels and amongst all types of employment (Fleming and Spicer, 2007). Research has revealed tendencies to misbehave – and es...

How can evolved human nature be leveraged to help eliminate or alleviate environmental problems? The authors examine the evolutionary bases of destructive and ecologically damaging human behavior. They propose that many modern environmental and social problems are caused or exacerbated by five adaptive tendencies rooted in evolutionary history: (1) propensity for self-interest, (2) motivation f...

Social smiling is universally regarded as being an infant's first facial expression of pleasure. Underlying co-constructivist emotion theories are the assumptions that the emergence of social smiling is bound to experiences of face-to-face interactions with caregivers and the impact of two developmental mechanisms--maternal and infant imitation.

Using the Nielsen Consumer Panel, we document the presence of significant price heterogeneity in the United States. Poor households pay lower prices for the same products, mostly because they shop more at discount stores. However, we also find that price heterogeneity has a very small impact on the measurement of consumption inequality. Adjusting nominal household expenditures by imposing that ...
