Question 1
What does current research evidence indicate about the appropriate way to explain the development of borderline personality disorder?
◦ It represents genetic factors exclusively.
◦ It represents a gene-environment correlation.
◦ It represents a gene-environment interaction.
◦ It represents environmental factors exclusively.
Question 2
What does the diathesis-stress model regarding the origins of schizophrenia propose?
◦ People who are genetically predisposed to schizophrenia will only develop the disorder if they are exposed to environmental or emotional stress during a critical period of development.
◦ Environmental factors contribute 60 percent to the development of schizophrenia, and genetic factors contribute 40 percent.
◦ People who are genetically predisposed to schizophrenia will develop schizophrenia because of their genetic predisposition, regardless of the type of environment in which they are raised.
◦ Gene-environment correlations are a larger determining factor in the development of schizophrenia than are gene-environment interactions.
