Which statement best describes how impulse-control task performance can be influenced?

• A. Performance is fixed and not influenced by motivation.
• B. Performance is only determined by task difficulty.
• C. Performance can be modulated by arousal and incentive/motivation.
• D. Performance is solely determined by age.

Answer: (C)

Performance on impulse-control tasks isn’t fixed; it changes with internal states like arousal and motivation. When someone is more aroused (more alert) and has a reason to perform well (a motivating incentive), they allocate more attention to the cues that require inhibition and engage the inhibitory control processes more effectively. This typically improves accuracy and the ability to withhold impulses, especially in demanding tasks such as go/no-go or stop-signal paradigms. Conversely, low arousal can reduce engagement and motivation can lead to slower, less precise responses. Moderate arousal tends to optimize control, while too much arousal can sometimes disrupt it, though the general pattern is that arousal and incentives modulate performance rather than leaving it fixed. The idea that performance is fixed, determined only by task difficulty, or driven solely by age doesn’t capture how motivation and arousal shape how well someone can control impulses in real situations.
