Trace conditioning differs from delay conditioning in which of the following ways?
A) Trace conditioning can be demonstrated in Aplysia,but delay conditioning cannot.
B) Trace conditioning does not require conscious processing by the forebrain,but delay conditioning does.
C) Delay conditioning involves a stimulus-free period between the conditioned and unconditioned stimuli,but the stimuli overlap in trace conditioning.
D) Trace conditioning involves a stimulus-free period between the conditioned and unconditioned stimuli,but the stimuli overlap in delay conditioning.

Quizplus · Accepted Answer

In delay conditioning, the conditioned stimulus is presented and remains until the unconditioned stimulus is presented. In contrast, trace conditioning involves a stimulus-free period (the trace interval) between the end of the conditioned stimulus and the beginning of the unconditioned stimulus. Therefore, option D is correct, as it correctly identifies a difference between trace and delay conditioning. Option A is incorrect because both types of conditioning have been demonstrated in Aplysia. Option B is incorrect because both types of conditioning likely involve some level of conscious processing. Option C is incorrect because it describes the opposite of what distinguishes trace and delay conditioning.
