Which of the following is NOT among the four influencers of the Inverted U Model?

• A. Skill Level
• B. Personality
• C. Trait Anxiety
• D. Motivation

Answer: (D)

The Inverted U Model shows how performance changes with arousal: performance typically rises with arousal to a peak, then declines if arousal becomes too high. Where you sit on that curve isn’t fixed; it shifts based on several individual and task-related factors.

Skill level matters because more capable performers can handle higher arousal before performance drops. If you’ve practiced a lot, moderate-to-high arousal can actually boost you to peak performance, whereas someone less skilled might peak at a lower arousal level.

Personality plays a role in how arousal affects you. People differ in their sensitivity to stress and stimulation; these personality differences help determine whether arousal moves performance up smoothly or makes you stumble earlier.

Trait anxiety specifically tweaks the curve by making arousal feel more threatening. Higher trait anxiety tends to lower the optimal arousal level, so performance can start to suffer at milder arousal.

The remaining factor typically considered is the task's demands or difficulty, which also influences the optimal arousal level: simpler tasks may benefit from higher arousal, while complex tasks require lower arousal for best results.

Motivation, while related to drive and persistence, isn’t usually listed as one of the four main influencers that adjust the shape of this curve in the standard formulation.
