· Mental disorder caused by psychological conflicts which originate in childhood and are unconcious
· Personality is composed of three interacting structures. When the stages of development are in conflict,
disorders arise
· Neurotic symptoms may represent compromises between these structures and reflect the stages of
development at which the conflict occured.
· Defence mechanisms serve to protect us from these conflicts.
· Id (pleasure principle, present at birth, impulsive and pleasure seeking: sexual and aggressive drives)
·Ego (reality principle, negotiates between id and superego, helps cope with reality)
· Superego (conscience and ego-ideal, governs moral judgements and feelings)

Negatives of Freud
· Early years are focused on too much, lacks interest in current problems
· Theory is largely unfalsifiable
· Not based on a solid foundation of scientific research, the case studies are
unrepresentative and unreliable.
· Findings were contaminated with biases and preconceptions
· Freud focused too much on sexual factors as the cause of mental disorders
· Reductionist as he ignores bio, cog and behavioural models
· Culture specific: applies to the sexually repressed Victorian period

· All behaviour is learned and so abnormal behaviour and disorders are also learned
· Nurture is everything and nature is ignored.
· Behaviour can be directly observed where mental processes cannot
· Through stimulus-response people learn and gradually simple behaviours combine
to produce complex behaviours
· Classical conditioning: Reflex behaviours or innate responses can be associated
with new stimuli. Pavlov and his dogs
· Operant conditioning: Positive and negative reinforcement, punishment and
· SLT: Learning through imitation. Watching and seeing the reinforcements that
