Which claim about the genetic contribution to psychological disorders matches the biological perspective as it stands today?
AOnly schizophrenia has any genetic component at all
BGenetic factors were ruled out once brain imaging improved
CMost psychological disorders have a genetic component
DGenetic risk is identical for every relative of a patient
Answer & Solution
Correct answer: C. Most psychological disorders have a genetic component
1. The biological perspective links disorders to genetic factors, chemical imbalances and brain abnormalities.
2. Evidence from many sources indicates that most psychological disorders have a genetic component, and for some the genetic contribution is not disputed.
3. Risk is not flat across a family: for schizophrenia, the closer the genetic relationship, the higher the risk.
4. Neural imaging strengthened rather than replaced the genetic account, since it revealed structural and functional abnormalities alongside it.
