If psychological and sociocultural explanations are to make the same kind of progress in understanding schizophrenia that biological explanations have,then they must:

Accepted Answer

In order for psychological and sociocultural explanations to make progress in understanding schizophrenia, they need to develop more precise theories that explain how these factors contribute to the development of the disorder. This may involve a combination of experimental research and other methods of inquiry. It is not necessary for these explanations to merge with biological approaches or to abandon their fields of study.

Question 12

If a patient developed extrapyramidal side effects after taking antipsychotic medication for several months,you would expect to see the patient showing primarily _____ dysfunction.

Accepted Answer

Extrapyramidal side effects are a common class of adverse reactions to antipsychotic medications that affect motor function. These side effects can include tremors, muscle spasms, rigidity, and other similar symptoms that reflect alterations in the patient's motor systems. There is typically no alteration in the patient's cognitive or emotional status, nor is there typically any change in their language or communication ability.

Choice A and B are incorrect because the duration of symptoms necessary for a diagnosis of schizophrenia is longer than two months. Choice C is incorrect because an individual must be in the active phase, not just delusional, for at least one month.

Question 15

Accepted Answer

Tardive dyskinesia symptoms typically manifest after prolonged use of certain medications, often taking six months or more to appear, which can lead to them being overlooked.

Question 16

All of these structures are part of a brain circuit that is linked to schizophrenia EXCEPT:

Accepted Answer

The superior colliculus is primarily involved in visual processing and eye movement control, and is not typically associated with the brain circuits linked to schizophrenia, unlike the prefrontal cortex, amygdala, and substantia nigra.

Question 17

Question 18

Which piece of evidence,if found,would weaken the dopamine hypothesis the most?

Accepted Answer

If drugs that bind to receptors other than dopamine reduce or eliminate the symptoms of schizophrenia, then it suggests that there may be other neurotransmitters or receptors involved in the development of the disorder, which weakens the dopamine hypothesis as the sole cause of schizophrenia. A, B, and D all support the dopamine hypothesis in some way.
