Developing strategies to improve older adults functional performance requires understanding real-world behaviors. An ecologically valid research approach provides deeper insights into aging and functional performance for real-world solutions.

Area of Science:

  • Gerontology
  • Human-Computer Interaction
  • Cognitive Science

Background:

  • Optimizing functional performance in older adults necessitates understanding their real-world task behaviors.
  • A key challenge is balancing contextual realism with the constraints of controlled research settings.

Purpose of the Study:

  • To present a research approach that enhances the ecological validity of research protocols.
  • To demonstrate how an ecologically valid approach offers greater insight into older adults' real-world performance.

Main Methods:

  • Utilized task analysis and simulation techniques.
  • Applied the approach to two research projects on aging and computer-based work task performance.

Main Results:
