What does the Coolidge Effect describe in sexual behavior?

• A. A decrease in sexual arousal with the same partner over time.
• B. A general decline in interest in sexual activity.
• C. Increased interest with the introduction of new sexual partners.
• D. No effect on sexual arousal.

Answer: (C)

The Coolidge Effect describes renewed sexual interest when a new partner is introduced. When an individual or animal becomes habituated to mating with the same partner, arousal tends to drop. Bringing in a different, novel partner re-engages the reward systems and arousal, leading to a surge in sexual interest again. This is why the best answer highlights increased interest with new sexual partners. It’s not about a general ongoing decline, no effect, or a simple decrease with time; the hallmark is the spike in arousal with novelty.
