• First explained by Fritz Heider (1958).
• Attribution theory proposes how people explain events and experiences in their lives, and the adaptational consequences of those explanations.
• Attribution theory  was developed in an attempt to understand why an event occurred so that later events can be predicted and controlled.

• Attribution refers to "the process of explaining one's own behavior and others".
• Attribution theory concerns with how individuals “attribute” or explain the behavior of other people, events, or their own behavior.
• Attribution theory proposes that people attribute a given behavior either to causes outside of the person or to some factor within the person who is performing the action (“dispositional” or “internal” factors).
• Responsibility for the behavior is assigned or not assigned depending on the
  attribution of the cause of the behavior.
• Factors that determine attribution include
  • effect on self-esteem (i.e., one’s bad behavior is more likely to be attributed to outside causes than is one’s good behavior),
  • universality of the behavior (everyone behaves in that manner, so it is just a habit or manifestation of conformity), and
  • unusual nature of the particular behavior at a given time.
• Causes of behaviour may be divided as two:
  • Situational - cause of behaviour is attributed to external factors such a delays or ration of others
  • dispositional - cause of behavior attributed to internal factors such as personality or character.
• People tend to attribute their successes to dispositional factors, and their failures to situational factors.
  • For example:  “I did well on the test because I am smart,” or “I did poor on the test because I didn’t get enough sleep.
• Attribution Errors
  • Fundamental attribution error refers to the tenancy for people to overestimate the influence of another person's internal characteristics on behaviour and underestimate the influence of situation.
