Summary

Cognitive performance over extended periods shows minimal impact from fatigue or practice effects. Long cognitive tasks do not significantly alter performance, reliability, or validity.

Area of Science:

  • Cognitive Psychology
  • Psychometrics

Background:

  • Extended cognitive testing may be influenced by fatigue and practice.
  • Performance decrements and changes in reliability/validity are potential concerns.

Purpose of the Study:

  • To investigate the separate effects of practice and fatigue on cognitive performance.
  • To analyze changes in task reliability and construct validity over time.

Main Methods:

  • Two studies (N=128, N=133) used quasi-experimental designs with intelligence and working memory tasks.
  • Participants completed parallel versions of tasks across different conditions to isolate practice and fatigue.
  • Fatigue questionnaires and personality scales were administered in one study.

Main Results:

  • Weak practice effects were observed.
  • Cognitive strain over several hours resulted in only trivial performance loss.
  • Reliability and correlations with criteria showed no significant changes.

Conclusions:

  • Extended cognitive testing sessions have minimal negative impact on performance.
  • Practice effects are weak, and fatigue does not significantly impair cognitive function or psychometric properties.
