Stress Performance Curve

The stress-performance curve, often referred to as the Yerkes-Dodson curve, is a psychological concept that describes the relationship between stress (or arousal) and performance. It suggests that there is an optimal level of stress or arousal for peak performance, and both too little and too much stress can result in reduced performance.

Here’s a breakdown of the stress-performance curve:

  1. Low Stress (Low Arousal): When an individual is under very low levels of stress or arousal, their performance tends to be suboptimal. This can be because they lack motivation or are too relaxed to perform at their best.
  2. Optimal Stress (Moderate Arousal): As stress or arousal increases from a low level, performance generally improves. This is the zone where individuals are most alert, motivated, and focused, leading to their best performance.
  3. Peak Performance (Optimal Arousal): At the peak of the curve, individuals experience their highest level of performance. They are neither too relaxed nor too stressed, striking the ideal balance between motivation and anxiety.
  4. Decreasing Performance (High Arousal): Beyond the optimal level of stress, as arousal continues to increase, performance starts to decline. This is often due to anxiety, decreased concentration, and a decrease in fine motor skills.
  5. Very High Stress (Very High Arousal): When stress or arousal becomes extremely high, performance can plummet drastically. Individuals may become overwhelmed, stressed, and unable to function effectively.

It’s important to note that the optimal level of stress or arousal can vary from person to person and also depends on the task at hand. Tasks that require a high level of focus and fine motor skills, such as surgery or precision manufacturing, may have a lower optimal arousal level, while tasks that benefit from high energy and excitement, like public speaking or sports, may have a higher optimal arousal level.

Additionally, individuals can develop skills and strategies to manage stress and optimize their performance within their own stress-performance curve. Techniques like relaxation, visualization, and mindfulness can help individuals find and maintain their optimal level of arousal for various tasks.
