The perception of self and others: Acquaintanceship, affect, and actor-observer differences.

Three studies were designed to examine how people perceive themselves versus others. The main finding was that people were seen as causing positive behaviors, and situational factors were regarded as causing negative behaviors (positivity effect). This positivity effect was found to operate most strongly for perceptions of intimate others, such as spouse and friends, and less strongly for strangers and liked and disliked acquaintances. There was little support for the actor-observer difference that people view their own behavior more situationally than they do other people's behavior. It was concluded that both cognitive and motivational factors must be considered in predicting how people perceive and describe others.
