This document summarizes key concepts in social perception and attribution. It discusses how person perception involves forming impressions of others based on observable factors like appearance, actions, and context. Impressions aim to understand traits and predict behavior. Attribution refers to inferring causes for people's behaviors and events. Attributions can be internal or external and stable/unstable. Theories like correspondent inference and covariance models examine how attributions are made. Biases like fundamental attribution error and self-serving attribution affect the impressions and explanations people form.
