Yerkes-Dodson Law

Describes the relationship between performance and arousal/stress with an inverse-U curve: increased arousal improves performance to a certain point, after which increased stress worsens performance.

Factors that shift the position of this U-curve include: (1) the difficulty of the task (2) how easily the individual becomes stressed (3) previous experience with the task being performed.

Key Insights & Principles

Stress & Performance

Insights:
  1. Optimal arousal is a midpoint between boredom and anxiety.
  2. Stress can enhance learning and performance on easy tasks, but impairs performance on difficult tasks.
  3. The complexity of tasks determines the energy and focus required to perform them, adding stress increases the level of energy depleted, and focus will suffer.
  4. Low arousal can mean low motivation to perform.
  5. Continued stress, even if low, can turn into distress over time.

Principles:
  1. Manage arousal by engaging or disengaging from activities - increase physical exercise to increase alertness, or take a break from difficult mental tasks to reduce stress.
  2. Introduce deadlines to tasks
