Older adults experienced more errors and slower response times on computer tasks. Age significantly impacted computer-based work performance, affecting fatigue and difficulty perceptions.

Area of Science:

  • Human-Computer Interaction
  • Gerontology
  • Cognitive Psychology

Background:

  • Computer use is prevalent across all age groups.
  • Understanding age-related performance differences is crucial for effective workplace design.

Purpose of the Study:

  • To examine the impact of age on computer-based work performance.
  • To evaluate how task complexity and pacing affect older adults' performance.

Main Methods:

  • Assessed 65 women aged 25-70 years performing three simulated computer tasks.
  • Utilized physiological, subjective, and objective performance measures.

Main Results:

  • Age and computer experience significantly influenced task performance.

  • Older participants exhibited longer response times and increased errors.
  • Age correlated with higher perceived fatigue and task difficulty.

    • Conclusions:

    • Age is a significant factor in computer-based work performance.
    • Job design and training programs should accommodate age-related changes in performance and perception.
