Which phenomenon describes a reduction in intrinsic motivation when external rewards are given?

• A. Intrinsic reduction
• B. Intrinsic enhancement
• C. External reinforcement
• D. Autonomy support

Answer: (A)

This question tests how external rewards can undermine intrinsic motivation. When someone is motivated from within—doing something because they find it enjoyable or interesting—adding rewards can shift the reason for doing the activity from internal satisfaction to the reward itself. Once the rewards are removed, the activity may seem less appealing, and motivation drops. This is known as the overjustification effect, so describing it as an intrinsic reduction fits best. For example, a student who loves playing sport might start practicing mainly to earn a prize; if the prizes stop, their motivation to participate may diminish. The other options describe different ideas: intrinsic enhancement would mean motivation grows, external reinforcement is a broader term about rewards shaping behavior, and autonomy support tends to boost intrinsic motivation rather than reduce it.
