Abstract

As an attempt to test the hypothesis that people's ingroup cognitive structure is more complex than the outgroup cognitive structure, as proposed by Linville(1982), an 2 x 2 x 2 designed experiment with independent subject groups was conducted in which in- versus out-group was differentiated by crossing 2 target groups and 2 subject groups. The third independent variable was source of list(adjectives derived from ingroup vs. adjectives derived from outgroup). Results showed a greater cognitive complexity for the ingroup as predicted in one subject group, but not in the other. An unexpected interaction effect observed between source of list and subject group further complicated the picture. Possible explanations of these results and implications for the subsequent research were discussed.
