A rat is given 20 exposures to a red light cue.Then, the red light is presented paired with food delivery.Compared to a rat that did not receive the initial 20 exposures, this rat took a long time to develop a CR to the red light.The slower learning is due to
A)the US-preexposure effect.
B)the latent-inhibition effect.
C)the latent-excitation effect.
D)the CS relevance effect.

Question

The slower learning in the rat that received the initial 20 exposures to the red light is due to the latent-inhibition effect, which occurs when prior exposure to a CS without any consequences leads to slower learning when the CS is later paired with a US. So, the rat may have learned to not respond to the red light during the initial exposures and therefore took longer to develop a CR when it was paired with food delivery.
