Trust reciprocity, a special form of link reciprocity, exists in many networks of trust among users. In this paper, we seek to determine the extent to which reciprocity exists in a trust network and develop quantitative models for measuring reciprocity and reciprocity related behaviors. We identify several reciprocity behaviors and their respective measures. These behavior measures can be emplo...

It was proposed that the emphasis of previous investigations of selfdisclosure reciprocity on descriptive reciprocation, the intimacy of the facts an individual reveals about himor herself, stems largely from the fact that these investigations have structured the circumstances for disclosure in terms of the exchange of information. If the circumstances were changed to a conversation or if parti...

In recent years a large number of experimental studies have documented the existence of strong reciprocity among humans. Strong reciprocity means that people willingly repay gifts and punish the violation of cooperation and fairness norms even in anonymous one-shot encounters with genetically unrelated strangers. We provide ethnographic and experimental evidence suggesting that ultimate theorie...

We define social reciprocity as the act of demonstrating one’s disapproval, at some personal cost, for the violation of widely-held norms (e.g., don’t free ride). Social reciprocity differs from standard notions of reciprocity because social reciprocators intervene whenever a norm is violated and do not condition intervention on potential future payoffs, revenge, or altruism. Instead, we posit ...

It is frequently believed that autism is characterized by a lack of social or emotional reciprocity. In this article, I question that assumption by demonstrating how many professionals-researchers and clinicians-and likewise many parents, have neglected the true meaning of reciprocity. Reciprocity is "a relation of mutual dependence or action or influence," or "a mode of exchange in which trans...

From the perspective of reciprocal altruism, we examined the role of reciprocity in the close relationships of people inflicted with a spinal cord injury (SCI) (n = 70). We focused on the help receiver rather than on the help giver. Participants perceived more reciprocity in relationships with friends than in relationships with the partner and with family members. In these last relationships, p...

The authors investigated the effects of expected reciprocity on knowledge sharing, as moderated by team and individual variables. Data (n = 84) was collected in an experimental study from undergraduate business student participants. Effects of expected reciprocity on knowledge sharing depended on the levels of individual competence, positive team attitudes, functional diversity and demographic ...

Recent evidence highlights the importance of social norms in many economic relations. However, many of these relationships are long-term and provide repeated game incentives for performance. We experimentally investigate interaction effects of reciprocity and repeated game incentives in two treatments (one-shot and repeated) of a gift-exchange game. In both treatments we observe reciprocity, wh...
