AP PSYCHOLOGY

Detailed explanation-1: -Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Some studies indicate an imbalance between the 2 may be the basis of the problem. Others have found a change in the body’s sensitivity to the neurotransmitters is part of the cause of schizophrenia.

Detailed explanation-2: -Cognitive explanations suggest that many symptoms of schizophrenia are caused by simple underlying problems with memory, perception and attention. Frith’s attention deficit theory suggests people with schizophrenia get overloaded by information because they can’t filter everything that’s happening around them.

Detailed explanation-3: -One weakness of the genetic explanation of schizophrenia is that there are methodological problems. Family, twin and adoption studies must be considered cautiously because they are retrospective, and diagnosis may be biased by knowledge that other family members who may have been diagnosed.

Detailed explanation-4: -One biological explanation for Schizophrenia is the Dopamine hypothesis. This proposes the idea that here is an excess amount of D2 receptors that causes the brain to release more dopamine as it believes more is needed.
