The Effects of Stress on Our Physiological, Perceptual, and Cognitive Performance

Part 2B

Humans employ three primary systems that aid in survival. Each of these systems will be either enhanced or degraded depending on the perceived stress level.

  1. The Physiological System is defined by elements of motor performance – simple, complex, and gross motor skills.
  2. The Perceptual System relates to our ability to process input from our five senses – primarily visual and auditory.
  3. The Cognitive System deals with the mind and includes the processing of information, judgment, decision making, and memory.
