A researcher in a classical conditioning experiment is attempting to condition a startle response to a green light. To do this, she illuminates the light, then it goes off and then she plays a very loud noise. This experiment is utilizing what type of sequence and timing of the CS-UCS pairing?
A)Forward short-delay pairing
B)Simultaneous pairing
C)Forward trace pairing
D)Backward pairing

In this experiment, the conditioned stimulus (green light) is presented first, followed by a short period where the light is turned off, and then the unconditioned stimulus (loud noise) is introduced. This sequence, where the CS is presented and ends before the UCS is introduced, with a gap or trace period in between, is known as forward trace pairing.
