Measuring Person Perception Accuracy: Another Look at Self-Other Agreement

The analysis of self-other data for the study of person perception accuracy is illustrated and discussed. Length of acquaintance, length of cohabitation, and trait empathy were investigated for their moderating effects on person perception accuracy, defined as the level of self-other agreement. Self-other agreement was computed four ways. A trait-by-trait analysis was performed twice, first using the moderator variable to form subgroups from which self-other correlations within each trait were computed and then using the moderator as a continuous variable in a series of moderated multiple regressions. Next, a profile analysis was performed that isolated two accuracy components, implicit profile accuracy and ideographic accuracy, which were conceptually similar to Cronbach's stereotype accuracy and differential accuracy components. The analyses, taken together, provided a componential and informative (if not comprehensive) analysis regarding accuracy as it is manifest in self-peer agreement data. Sex and cohabitation length moderated accuracy whereas acquaintance length and trait empathy did not.
