what is the behavioural explanation
schizophrenia is learned from the environment and if it is positively reinforced it will be repeated but frequent punishment leads to a decrease in the frequency. Similarly, if reinforcement is observes, the patient is likely to reproduce the behaviour. The behaviour is maintained by operant conditioning after being onset by SLT
