Human cooperation may partly depend on the presence of individuals willing to incur personal costs to punish noncooperators. The psychological factors that motivate such 'altruistic punishment' are not fully understood; some have argued that altruistic punishment is a deliberate act of norm enforcement that requires self-control, while others claim that it is an impulsive act driven primarily b...

Prior studies find that gay men and lesbians volunteer in HIV/AIDS service organizations at high rates. However, no population-based study has investigated the mechanisms involved. Using data from the General Social Survey, a nationally representative biennial survey that in 2002 and 2004 interviewed 2031 sexually experienced adults, the authors examine levels of empathic concern, altruistic va...

A field study of altruistic behaviour is presented using a modification of the dictator game in a large random sample survey in the Netherlands (n=1,964). In line with laboratory experiments, only 5.7% donated money. In line with other survey research on giving, generosity increased with age, education, income, trust, and prosocial value orientation.

When adding up the benefits to be compared with costs, should we sum the private valuations, the altruistic valuations, or something else? This paper proposes a partial answer and offers some suggestions for benefit-cost practitioners.

Possible gender stereotypes associated with altruistic acts presented in two types of vignettes were investigated. A sample of 72 General Psychology students were recruited to participate. The researchers had three main hypotheses: Females would more likely be perceived as the performers of an altruistic act, females would more likely be perceived as the receivers of an altruistic act, and the ...

In the Ultimatum Game (UG), incurring a cost to punish inequity is commonly termed altruistic punishment. This behaviour is thought to benefit others if the defector becomes more equitable in future interactions. However, clear connections between punishment in the UG and altruistic behaviours outside the laboratory are lacking. We tested the altruistic punishment hypothesis in a sample of extr...

Hedonic games are coalition formation in which players have preferences over the coalitions they can join. For a long time, all models of representing hedonic were based upon selfish only. Among known ways compactly, we focus on friend-oriented and propose novel model for them that takes into account not only players’ own but also their friends’ preferences. Depending order look at or preferenc...
