25
Explain Meehl's theory of the etiology of schizophrenia?
1. some people are born with a diathesis (предрасположенность) called "hypokrisia" 2. this means that there are problems in the structure of the neurons of the brain 3. this means that the ideas in the person's head are associated with each other in unusual patterns 4. so the person will speak strangely and have problems with attention, called "cognitive slippage" 5. the person will be rejected and isolated by others, called "aversive drift" 6. if all these factors come together and the person also has a large stress during adolescence, it will cause schizophrenia
