Question

Quizplus · Accepted Answer

The neutral stimulus is the knock on the door, the CS is the knock on the door (which becomes associated with the expected arrival of the dealer), and the UCS is cocaine (which activates the sympathetic nervous system and causes physical symptoms like shaking and a pounding heart). Option A is incorrect because it identifies cocaine as the neutral stimulus, which is not accurate. Option B is incorrect because it identifies the pounding heart as the UCS, which is actually caused by the UCS (cocaine). Option D is incorrect because it identifies cocaine as both the neutral stimulus and the UCS, which is not accurate.
