THEORIES OF AGGRESSION Aggression as innate instinct • Freud (1930) – psychodynamic theory • Lorenz (1966) ethological theory • Sociobiology Aggression as goal-directed drive • Frustration-aggression hypothesis (Dollard et al, 1939) • Berkowitz’ 1989 reformulation Aggression mediated by cognitive appraisal • Excitation-transfer model (Zillman, 1979)

Aggression as learned behaviour • Social learning theory (Bandura, 1977)

Evaluation of instinct approach

• lacks empirical evidence

based on limited & biased observation of human aggression

• relies on notion of 'energy' that is unknown, unknowable, unmeasurable

• not useful in prevention or control of aggression

Zillmann, 1979, 1988 excitation transfer model

-> aggression = a function of: learned behaviour excitation from another source

-

aggression results from transfer of arousal from one situation to another if arousal attributed to s’thing in current situation
