This research examined how the relative status levels of groups affected th
eir propensity to accept pressures to form a common superordinate group ent
ity. Using measures of cooperation (Tajfel matices) and reaction time respo
nses, results showed that low status groups were unlikely to form a unified
group representation under mutual-goal conditions. In addition, low status
groups showed lower levels of cooperation than did groups of relatively hi
gher status. Results support Seta and Seta's (1992, 1996) social hierarchy
analysis of social identification and suggest that intra-group social compa
risons mediate group members' willingness to break down group boundaries an
d form unified superordinate group structures. This research has implicatio
ns for the potential success of efforts to reduce prejudice through group i
ntegration.
