Evidence that adjunctive processes contribute to drug abuse includes the fact that:
A) schedule-induced polydipsia has been used to induce rats to drink excessive amounts of water containing drugs.
B) drug abuse is frequently found in settings that provide sparse levels of reinforcement.
C) Both a and b are correct.
D) Neither a nor b is correct.

Question

Quizplus · Accepted Answer

Both A and B are correct because schedule-induced polydipsia demonstrates how non-drug reinforcers can lead to excessive drug intake in an experimental setting, and the observation that drug abuse often occurs in environments with limited alternative sources of reinforcement supports the role of adjunctive processes in the development of drug abuse.
