RT Journal Article T1 Trust matters: a cross-cultural comparison of Northern Ghana and Oaxaca groups. A1 Acedo-Carmona, Cristina A1 Gomila Benejam, Antoni K1 Cooperación (Psicología) K1 Confianza - Aspectos sociales K1 Psicología social AB A cross-cultural analysis of trust andd cooperation networks in Northern Ghana (NGHA) and Oaxaca (OAX) was carried out by means of ego networks and interviews. These regions were chosen because both are inhabited by several ethnic groups, thus prividing a good opportunity to test the cultural group selectio hypothesis. Against the predictions of this approach, we found that in both regions cooperation is grounded in personal trust groups, and that social cohesion depends on these emotional bonds. Moreover, in apreement with Fiske's notion of "evolved proclivities", we also found two distinct kinds of trust networks, one for each region, which vary in terms of the degree of ethnic interrelation. This pattern suggests that social cohesion increases when environmental resources are scarce.
