PrepTest 66, Section 2, Question 4
Traditional "talk" therapy, in which a patient with a psychological disorder discusses it with a trained therapist, produces chemical changes in the brain. These changes seem to correspond to improvements in certain aspects of the patient's behavior. Thus, physicians will eventually be able to treat such patients as effectively through pharmacological intervention in the brain's neurochemistry as through the lengthy intermediary of traditional "talk" methods.

Which one of the following is an assumption on which the argument depends?
All neurochemical changes produce corresponding psychological changes.
Improvements in a patient's behavior produced by "talk" therapy occur only through chemical changes in the brain's neurochemistry.
"Talk" therapy has not been effective at bringing about psychological change.
If chemical changes in the brain's neurochemistry correspond to improvements in patient behavior, then psychology and neuroscience will eventually be indistinguishable.
Direct intervention in the brain's neurochemistry is likely to become a less expensive way of treating psychological disorders than is "talk" therapy.
