Abstract
This study tested, in a natural setting, the effect of mimicry on people's disposition toward helping others and the extent to which this helping behavior is extended to people not directly involved in the mimicry situation. In the main street of a busy town, men (n = 101) and women...

Abstract
The notion of 'integrity' remains relatively unexplored in the social psychological literature, despite it being central to some important theoretical perspectives (notably, self-affirmation theory). It is an eminently positive - and well-used - epithet in descriptions of public figures. The two stud...

Because nurses deliver care to patients on behalf of hospitals, hospitals have to enhance first-line nurses' patient-oriented perception and spontaneous organizational citizenship behaviors for the sake of higher patient satisfaction and better patient care.

We examined the neural basis of extraordinary empathy and altruistic motivation in African-American and Caucasian-American individuals using functional magnetic resonance imaging. Our results indicate that empathy for ingroup members is neurally distinct from empathy for humankind, more generally. P...

Abstract
I tested cotton-top tamarins in a preferential giving task. Subjects could choose from two tools, one of which delivered food to a partner in an adjacent cage and the other of which delivered food to an empty cage. Thus, subjects could preferentially give or withhold food from a partner. I varied wh...

We replicate Jensen et al.'s procedure in humans with money. When waiting 1 min to reject, humans favor punishing over maximizing; however, when rejection requires 5 min of inaction, humans, like apes, maximize. If species differences in time horizons are accommodated, Jensen et al.'s ape data are r...

There is evidence that a tendency to share resources equitably among members of a social group emerges in middle childhood. It is regarded by many investigators as a central and unique feature of human social life. In this work the relative roles of developmental processes and collective effects gen...

We empirically test between these alternatives by decoupling imperfect behavior from prosocial preferences in modified versions of the public goods game, in which individuals would maximize their selfish gain by completely (100%) cooperating. We found that, although this led to higher levels of coop...

We investigate the impact of eye cues on trustees' altruistic behaviour in a trust game and find zero effect. Neither the subjects who are classified as prosocial nor the subjects who are classified as selfish respond to these cues. In sharp contrast to the irrelevance of subtle reputation cues for...

It has been suggested that because certain moral virtues, including altruism and kindness, are sexually attractive, their evolution could have been shaped by the process of sexual selection. Ou...

Self-determination theory posits that the degree to which a prosocial act is volitional or autonomous predicts its effect on well-being and that psychological need satisfaction mediates this relation. Four studies tested the impact of autonomous and controlled motivation for helping others on well-b...

We review answers from evolutionary theory, sociology, and economics. Sometimes in direct conflict with each other, these accounts of grandparental investment exist side-by-side, with little or no theoretical integration. They all account for some of the data, and none account for all of it. We call...
