Sc. Wright et al., THE EXTENDED CONTACT EFFECT - KNOWLEDGE OF CROSS-GROUP FRIENDSHIPS AND PREJUDICE, Journal of personality and social psychology, 73(1), 1997, pp. 73-90
The extended contact hypothesis proposes that knowledge that an in-gro
up member has a close relationship with an out-group member can lead t
o more positive intergroup attitudes. Proposed mechanisms are the in-g
roup or out-group member serving as positive exemplars and the inclusi
on of the out-group member's group membership in the self. In Studies
1 and 2, respondents knowing an in-group member with an cut-group frie
nd had less negative attitudes toward that our-group, even controlling
for dispositional variables and direct out-group friendships. Study 3
, with constructed intergroup-conflict situations (on the robbers cave
model), found reduced negative out-group attitudes after participants
learned of cross-group friendships. Study 4, a minimal group experime
nt, showed less negative out-group attitudes for participants observin
g an apparent in-group-out-group friendship.
