How does arousal affect performance?
Sources:
Arousal significantly impacts performance, with its effects varying based on the type and level of arousal and the context of the task.
-
Challenge vs. Threat: High arousal can manifest as either a challenge state (positive stress) or a threat state (negative stress). When arousal is perceived as a challenge, it can enhance performance by increasing confidence and the belief in one's ability to handle the situation. Conversely, when perceived as a threat, it can impair performance due to anxiety or fear of failure 1 2.
-
Optimal Performance State: The optimal performance state involves a balance where internal autonomic arousal (stress or alertness) matches the demands of the task. Higher autonomic arousal is beneficial for high-stakes or fast-paced tasks because it enhances focus and quick response times. In contrast, for tasks that require learning or precision, a more relaxed state may be preferable 3 4.
-
Physiological and Psychological Interactions: The perception of stress and the body's physiological preparation for stress can affect performance. For example, voluntary exposure to stress (e.g., preparing for a challenging workout) can increase testosterone and improve performance. However, involuntary stress may lead to different physiological outcomes 5.
-
Time Perception and Focus: High arousal states can alter time perception, allowing for better focus and quicker processing of information. This is useful in situations where rapid decision-making and responses are crucial 6 3.
Understanding and managing arousal levels can thus be key to optimizing performance in various contexts, whether aiming for high physical exertion, precise skills, or rapid cognitive tasks.
