In adolescence, aspects of cognition that are required to deal with complex cooperation situations, such as mentalising and social value orientation, are still in development. In the Trust Game, cooperation may lead to better outcomes for both players, but can also lead to exploitation by the trustee. In the present study, we explore how mindreading, a crucial aspect of mentalising, and social ...

In social networks, trust can have two aspects: trust of users to social network and trust of users to other users. Pear to pear networks, by eliminating the supervisor roles, besides its benefit in decreasing management costs, have problems in trust and security of use...

Hence, due to the importance of the subject, the sociological explanation of the impact of social capital on forms of alienation has been di...

Yet, the transfer of the multi-facetted concept of trust to virtual social networks is an open challenge. In this paper we provide a survey and classification of established and upcoming trust systems, focusing on trust models. We introduce a set of criteria as basis of our anal...

A violation of trust can have quite different consequences, depending on the nature of the relationship in which the trust breach occurs. In this article, we identify a key relationship characteristic that affects trust recovery: the extent of relationship experience before the trust breach. Across two experiments, this investigation establishes the behavioral effect that greater relationship e...
