alternatives to the medical model Flashcards
what ways can behaviour be modelled?
learning behaviours; thinking processes; emotional processes; biological processes
what does the behavioural model assume?
abnormal behaviour is the consequence of abnormal learning from the environment. there is no qualitative difference between normal and abnormal behaviour as they are all learned in the same way
how does the behavioural model believe behaviour is learned?
classical conditioning, operant conditioning, social learning theory- what is learned can be unlearned
what is learning by assosciation?
when two environmental changes occur together, we learn to associate them- and the response from one may transfer to another
how does learning by association affect mental illness?
reactions such as phobias can be learned, e.g., being startled when someone screams at a spider, and we then learn to associate spiders with that fear.
what is learning by consequence?
the likelihood of individuals repeating behaviour depends on its consequence
how does learning by consequence affect mental illness?
e.g., we feel anxious about an action, so we avoid it. this removes the anxiety and negatively reinforces the behaviour.
what is learning by observation?
people observe the behaviour of those around them, and may imitate this behaviour depending on the observed consequences
how does learning by observation affect mental illness?
if someone grows up around people with mental illnesses, they may learn to imitate this behaviour
what are some behavioural treatments?
systematic desensitisation; aversion therapy; flooding
what is systematic desensitisation?
based on classical conditioning, where patients learn to relax and are taken through a hierarchy of increasingly frightening stimuli whilst relaxing.
- mcgrath (1990) found this worked with a ten-year-old girl who had a fear of loud noises and assosciated objects such as balloons and party poppers.
what is aversion therapy?
where patients learn to link negative associations to objects
what is flooding?
unlearning associations all at once by being exposed to the stimulus
benefits of the behavioural explanation
provides a simple, testable explanation that is supported by experimental evidence; hopeful, as it predicts that people can change their behaviour
- shown to be effective with reducing symptoms of schizophrenia. paul and lentz (1977) gave schizoprhenic patients therapy based on social learning theory and operant conditioning -> became twice as likely to be discharged from hospital
limitations of the behavioural explanation
criticised as being dehumanising and mechanistic by reducing people to programmed stimulus-response units; cannot explain all psychological disorders; cannot cure conditions such as schizophrenia
what does the cognitive model assume?
dysfunctional behaviour is caused by faulty or irrational thoughts, and we interact with the world through our mental representation of it- so inaccurate representations may cause behaviour to become distorted
what are irrational beliefs?
where people suffering from anxiety or depression believe they are unloved and nothing good will ever happen
what does beck believe?
depressed people have acquired negative schemas in childhood that are activated around new experiences- leads to the expectation of failure
