Four investigations examined the dynamics between the individual self (self
-representation independent of group membership) and the collective self (s
elf-representation derived from group membership). Relative to participants
whose collective self was threatened, participants whose individual self w
as threatened (a) considered the threat more severe, (b) experienced a more
negative mood, (c) reported more anger, and (d) derogated to a greater ext
ent the source of threat. In addition, a self-description task indicated th
at participants generate more aspects of their individual than collective s
elf. These effects occurred even when confounding variables (i.e., accessib
ility of the selves, group identification, individualism and collectivism,
importance of threat domain) were controlled. The individual self is motiva
tionally primary.
