Question

1 A biological perspective would be LEAST helpful for explaining the dramatic increase in reported cases of dissociative identity disorder during the past 40 or so years. prevalence of schizophrenia throughout the world. fear of snakes experienced by a high percentage of Americans. fluctuations in mood experienced by those suffering a bipolar disorder. twin studies indicating high correlations in rates of psychological disorders between twins raised in different families.

Answer 1

The biological perspective would be least helpful for explaining the increase in dissociative identity disorder rates, attributed more to cultural and diagnostic factors, but is relevant to biological aspects of schizophrenia, bipolar disorder, and the fear response.

Step-by-step explanation:

A biological perspective in psychology emphasizes the physical and biological bases of behavior, including genetic, hormonal, and neurochemical explanations. This approach would be least helpful for explaining the dramatic increase in reported cases of dissociative identity disorder (DID) over the past 40 years. The rise in DID cases has been attributed more to cultural and diagnostic factors than to biological changes. On the other hand, the biological perspective is quite relevant to the prevalence of schizophrenia, the biological underpinnings of fear (like the fear of snakes), fluctuations in mood in bipolar disorder, and the high correlations found in psychological disorders through twin studies. Schizophrenia and bipolar disorder, for example, have well-researched biological components, such as malfunctions in dopaminergic neurons in schizophrenia and neurotransmitter imbalances in bipolar disorder, making the biological perspective very useful in these contexts.

Answer 2

dramatic increase in reported cases of dissociative identity disorder during the past 40 or so years.

Step-by-step explanation:

Biological perspective: The term "biological perspective" is described as a specific way of considering psychological issues through studying the "physical basis or cause" for human and animal behavior. It is considered one of the "major perspectives" and encompasses certain things like studying the immune system, genetics, brain, and nervous system. Therefore, the biological perspective tends to believe that most behavior is being inherited and possess an evolutionary or adaptive function.
