Social transmission and shared reality in cultural dynamics.

Micro cultural dynamics are concerned with the mechanisms of transmission, retention, and modification of cultural information in social networks. When interacting individuals mutually recognize that they share psychological reactions to given cultural information, it may be grounded as an aspect of their shared reality under specifiable conditions. The interpretation of cultural information as socially verified shared reality provides a basis for further dissemination of the information and coordinated social action. We review the recent literature that supports this general contention, while highlighting the role of emotion-a somewhat under-recognized aspect of shared reality research-and emphasizing the mediating role of cultural dynamics in the mutual constitution of social reality and shared reality.
