Aspects of personality: Interactionist perspective.

The idea

The interactionist perspective explains behaviour as the product of both personality traits and the situation, rather than either alone. Traits predispose a performer towards certain responses, but the specific situation, including the demands of the task, the presence of others and the consequences, determines whether and how that predisposition is expressed. For example, a performer with a strong trait of competitiveness may be assertive in a close match but quiet in a training drill that offers no reward for assertiveness. This perspective is often represented as behaviour being a function of personality and environment together, and it underpins approaches such as the trait-situation debate resolution.

What earns the marks

• Interactionist perspective combines trait and situational explanations rather than choosing one over the other.
• Behaviour is influenced by enduring personality characteristics and by the specific situation in which the performer acts.
• The same trait can produce different behaviour in different situations, depending on task demands, audience and consequences.
• The perspective is often summarised as behaviour being a function of personality and environment interacting.
• Applied implication: coaches should consider both the performer's typical tendencies and the features of the current setting when predicting or shaping behaviour.

Common mistakes and how to put them right

• Misunderstanding: interactionism means the situation always overrides personality.

  Put it right: Both contribute, and their relative influence can vary by person and context.

• Misunderstanding: interactionism is the same as trait theory with a different name.

  Put it right: It explicitly includes situational factors, which trait theory alone underplays.

• Misunderstanding: interactionism is the same as social learning theory.

  Put it right: Social learning emphasises learning and reinforcement, while interactionism emphasises the joint influence of traits and situations.

• Misunderstanding: interactionism predicts behaviour perfectly.

  Put it right: It improves prediction by combining factors but does not guarantee exact forecasts.

Exam tips

• Look for stems that mention both a personal characteristic and a situational factor; these point to the interactionist perspective.
• Reject options that claim only personality or only the situation determines behaviour.
• Use the phrase 'personality and environment together' as a quick check when choosing between similar options.
