Trust based attachment

In social systems subject to indirect reciprocity, a positive reputation is key for increasing one's likelihood of future positive interactions. The flow of gossip can amplify the impact of a person's actions on their reputation depending on how widely it spreads across the social network, which leads to a percolation problem. To quantify this notion, we calculate the expected number of individuals, the "audience", who find out about a particular interaction. For a potential donor, a larger audience constitutes higher reputational stakes, and thus a higher incentive, to perform "good" actions in line with current social norms. For a receiver, a larger audience therefore increases the trust that the partner will be cooperative. This idea can be used for an algorithm that generates social networks, which we call trust based attachment (TBA). TBA produces graphs that share crucial quantitative properties with real-world networks, such as high clustering, small-world behavior, and power law degree distributions. We also show that TBA can be approximated by simple friend-of-friend routines based on triadic closure, which are known to be highly effective at generating realistic social network structures. Therefore, our work provides a new justification for triadic closure in social contexts based on notions of trust, gossip, and social information spread. These factors are thus identified as potential significant influences on how humans form social ties

Teens, Social Media, and Privacy

Teens share a wide range of information about themselves on social media sites; indeed the sites themselves are designed to encourage the sharing of information and the expansion of networks. However, few teens embrace a fully public approach to social media. Instead, they take an array of steps to restrict and prune their profiles, and their patterns of reputation management on social media vary greatly according to their gender and network size

Social Functioning of Children and Their Parents: Are They Related?

This study examined whether parents' social support was related to their children's peer acceptance and likability. The moderating role of the parent's and the child's gender was also examined. Father (N = 146-150) and mother (N = 201) reports of social support and peer reports of peer acceptance were obtained from 107 boys and 96 girls (7.92-16.76 years, M = 11.77). Aspects of fathers' and mothers' social support were observed to be differentially correlated with their children's friendships and likability. While fathers' social support was moderately correlated with their children's friendships, mothers' social support was not. The implications of these findings for the role of fathers in children's social functioning are discussed
