1) Attribution theory examines how people explain events and behavior through internal (personal) or external (situational) causes. Heider found people tend to overestimate internal causes and underestimate external causes, known as the fundamental attribution error.
2) Jones and Davis found people tend to infer stable personality traits from behavior, known as correspondent inference. However, such inferences can be ambiguous without considering context.
3) Kelley's covariation model examines consistency, distinctiveness, and consensus to determine causal links between events and behavior. This helps systematically analyze attribution.
