This document discusses perception and attribution theory. It defines perception as how individuals give meaning to their environment by interpreting sensory impressions. Attribution theory seeks to explain how people make judgments of others based on whether they attribute behaviors to internal or external causes. There are several factors that influence perceptions and attributions, including personal characteristics, attitudes, motives, expectations, distinctiveness, consensus, and consistency of behaviors. People also tend to attribute their own successes to internal factors while blaming failures on external factors in a self-serving bias. Cultural differences can also impact how people make attributions.
