Costly signaling theory (CST) offers an explanation of generosity and collective action that contrasts sharply with explanations based on conditional reciprocity. This makes it particularly relevant to situations involving widespread unconditional provisioning of collective goods. We provide a preliminary application of CST to ethnographic data on turtle hunting and public feasting among the Me...

Promise is one of the most powerful tools producing trust and facilitating cooperation, and sticking to the promise is deemed as a key social norm in social interactions. The present study explored the extent to which promise would influence investors' decision-making in the trust game where promise had no predictive value regarding trustees' reciprocation. In addition, we examined the neural u...

OBJECTIVE To characterize dyadic and general friendships of youth with spina bifida (SB). METHODS Families of youth with SB recruited a peer to participate; 106 dyads participated. Youth with SB and peers completed questionnaires and interviews regarding characteristics of the dyadic friendship and each individual's general friendships. RESULTS Youth with SB and their peers were similar in ...

My primary research interest is social behavior for software agents to achieve cooperation in general-sum normal form games. An agent can easily be programmed to constantly cooperate in a normal form game, but such an agent is not suitable for environments with potentially hostile opponents. For a rational agent, the main reason to cooperate is to induce reciprocation therefore it is necessary ...

Abstract A growing body of research can be found in which roboticists are designing for reciprocity as a key construct successful human–robot interaction (HRI). Given the centrality component our moral lives (for development and maintaining just society), this paper confronts possibility what things would look like if benchmark to achieve perceived were accomplished. Through an analysis value f...

Faces contain certain cues that can be used to infer the intentions of other people and to formulate beliefs about them. The present study explored the extent to which the race of the partners and their emotional facial expressions influenced participants' decision-making in a Trust Game where race and emotional expression had no actual predictive value regarding the partners' reciprocation rat...

Social exchange (P. Blau, 1964) and the norm of reciprocity (A. W. Gouldner, 1960) have been used to explain the relationship of perceived organizational support and leader-member exchange with employee attitudes and behavior. Recent empirical research suggests that individuals engage in different reciprocation efforts depending on the exchange partner (e.g., B. L. McNeely & B. M. Meglino, 1994...

Considerable evidence suggests that economic interdependence and integration reduce the likelihood of militarized conflict. However, scholars have devoted remarkably scant attention to testing different explanations of the liberal peace. This article offers an empirical test that can help adjudicate the two main arguments on the liberal peace: the opportunity cost and signaling arguments. Under...

Cultures are built on social exchange. Most languages have dedicated grammatical machinery for expressing this. To demonstrate that statistical methods can also be applied to grammatical meaning, we here ask whether the underlying meanings of these grammatical constructions are based on shared common concepts. To explore this, we designed video stimuli of reciprocated actions (e.g., "giving to ...

We build on the social heuristics hypothesis, the literature on the glucose model of self-control, and recent challenges on these hypotheses to investigate whether individuals exhibit a change in degree of trust and reciprocation after consumption of a meal. We induce short-term manipulation of hunger followed by the trust game and a decision on whether to leave personal belongings in an unlock...
