T. Mussweiler et F. Strack, The "relative self": Informational and judgmental consequences of comparative self-evaluation, J PERS SOC, 79(1), 2000, pp. 23-38
Results of 5 studies demonstrated that self-evaluative comparisons have 2 d
istinct informational consequences with opposing judgmental effects: They s
electively increase the accessibility of standard-consistent self-knowledge
and provide an evaluative reference point. The first informational consequ
ence produces assimilation in self-evaluative judgments, whereas the latter
yields contrast. Using a lexical decision task, Study 1 demonstrated that
a social comparison selectively increases the accessibility of standard-con
sistent self-knowledge. Study 2 showed that this effect also holds for comp
arisons with objective standards. Studies 3 and 4 revealed that the same co
mparison may lead to assimilation on objective and contrast on subjective s
elf-judgments. Finally, Study 5 demonstrated that assimilation results for
comparisons with relevant and irrelevant standards, whereas contrast occurs
only for relevant standards.
