 Psychological communities, or communities of face-to-face personal interaction governed by sentiments of trust, co-operation, and altruism. This refers to a group of persons who participate in common activity and experience a psychological sense of togetherness as shared ends are sought. Such communities, based on face-to-face interaction, are governed by sentiments of trust, cooperation, and altruism in the sense that constituent members have the good of the community in mind and act on behalf of the community’s interest. They differ from communities of place by not being necessarily defined by locality and proximity. The differ from communities of memory in the sense that they are more “real”, they are typically based on face to face social interaction at one point in time and consequently tend to be restricted in  size.[14]  The family is the prototypical example. Other examples include small-scale work or school settings founded on trust and social cooperation.
