15. Stress Effects on Cognition How does fatigue affect performance?

16. The Yerkes-Dodson Law High & low stress/arousal can lead to impaired performance by reducing resource availability High & low stress/arousal can lead to impaired performance by reducing resource availability Novice or Expert or

17. Stress Effects on Cognition If your attention is reduced, information processing in cognitive capacity will suffer. If your attention is reduced, information processing in cognitive capacity will suffer. Tunneling & lapsing can occur here

18. Fatigue Effects on Cognition attentional lapses attentional lapses some slowing of information processing some slowing of information processing Attention & working memory are compromised.

19. Reduced Attentional Resources Cause… Lapses in attention Lapses in attention Slowing of information processing Slowing of information processing Information not processed as ‘deeply’ Information not processed as ‘deeply’ Attentional narrowing/tunneling Attentional narrowing/tunneling “Satisficing ” “Satisficing ” Task shedding Task shedding Reliance on automated performance Reliance on automated performance Reliance on schemas/templates Reliance on schemas/templates

20. Stress Effects on Cognition High Arousal or Preoccupation High Arousal or Preoccupation Reduced attentional capacity Reduced attentional capacity Attentional tunneling Attentional tunneling Perceptual Perceptual Working memory Working memory Reduced working memory capacity Reduced working memory capacity Less effective memory storage & recall Less effective memory storage & recall Compromised: Attention, Working Memory, Retrieval from Long Term Memory
