Male Japanese quail became sexually aroused by a red light that was repeatedly associated with the presentation of a female quail. The sexual arousal triggered by the red light was a?

Conditioned response.

Explanation:

Conditioned response may be defined as a type of learned behavior used in the Pavlov experiment. This type of response mainly generated when the neutral stimulus get mixed with the strong stimulus.

The male quail can be sexually arouse by red light. The red light here acts as the conditioned response because the neutral stimulus (red light) when mixed with the unconditioned stimulus result in the presentation of the female quail and increases the response of the male quail.

Thus, the correct answer is conditioned response.
