People make judgments about others all the time, often without realizing they are doing so. How are interpersonal impressions formed? How accurate are our perceptions of other peoples traits--and our own? In this major revision of his landmark work, David A. Kenny provides a reader-friendly examination of these and other critical questions, identifying key components that shape impressions and their accuracy. Topics include how to estimate perceiver, target, and relationship effects; the extent to which different perceivers see a target in the same way; the impact of group membership and stereotypes; and whether others see us as we see ourselves. Implications for interpersonal relationships and social behavior are highlighted.
