Older adults improve computer task skills with practice. Age and fluid intelligence impact initial performance and quality improvement, while crystallized intelligence and age affect processing speed.

Area of Science:

  • Gerontology
  • Human-Computer Interaction
  • Cognitive Psychology

Background:

  • Skill acquisition in older adults is crucial for digital inclusion.
  • Understanding factors influencing learning in older populations informs training design.
  • Computer-based tasks are increasingly relevant in professional settings.

Purpose of the Study:

  • To investigate the influence of age, cognitive abilities, prior experience, and knowledge on skill acquisition in a simulated customer service task.
  • To identify predictors of initial performance levels and rates of improvement.
  • To inform the design of targeted intervention strategies for older adult learners.

Main Methods:

  • Fifty-two participants aged 50-80 completed a 4-day computer-based simulated customer service task.

  • Cognitive abilities and prior computer experience were assessed using a comprehensive battery.
  • Performance metrics included overall quality, efficiency, and email processing time.

    • Main Results:

    • Performance quality and efficiency significantly improved with practice.
    • Age and fluid intelligence predicted initial performance and improvement in task quality.
    • Crystallized intelligence and age predicted initial email processing time, with crystallized intelligence also predicting its rate of change.

    Conclusions:

    • Older adults demonstrate significant skill acquisition in computer-based tasks with practice.
    • Cognitive factors like fluid and crystallized intelligence play distinct roles in different aspects of performance and learning.
    • Findings support the development of tailored training programs considering individual cognitive profiles and age-related differences.
