Final answer:
To achieve high performance on a simple task, the Yerkes-Dodson law recommends high arousal (Option A). This law states that simple tasks are performed best with higher arousal levels, while complex ones require lower arousal for optimal performance.
Step-by-step explanation:
To achieve high performance on a simple task, according to the Yerkes-Dodson law, a higher level of arousal is recommended. This law suggests that there is an optimal level of arousal for the best performance on a task which depends on the task's complexity.
For simple tasks, higher arousal can be beneficial, leading to better performance due to increased alertness and energy. On the other hand, complex tasks typically require a lower level of arousal for optimal performance, as too much arousal can impede concentration and result in errors.
In practical terms, moderate anxiety or stress can be motivating and enhance performance (eustress), but when stress exceeds an optimal level, it becomes detrimental (distress).
This relationship between arousal and performance is represented as an inverted U-shaped curve, where performance is maximized at an optimal arousal level, with performance outcomes declining when arousal becomes either too low or too high.
Applying this to academic scenarios, a student may experience low arousal, such as apathy towards studying, leading to poor performance. Conversely, extremely high arousal, such as extreme anxiety, can lead to paralysis by stress, negatively affecting outcomes.
Hence, to answer the original question, on a simple task, a higher but not overwhelming level of arousal (Option A: High arousal) is recommended for achieving high performance according to the Yerkes-Dodson law.
