Overview

Factorial study reveals care home environmental preferences using brain activity and surveys in older adults, highlighting design strategies for emotional well-being.

Key Points

  • To identify older adults' preferences regarding specific care home environmental attributes to create emotionally supportive spaces that enhance psychological well-being.
  • Implemented a fractional factorial design evaluating 32 scenes generated from eight environmental attributes at two levels each: illuminance, colour temperature, view out, floor texture, colour contrast, visual complexity, layout, and style.
  • Acquired 111 valid datasets using electroencephalography (EEG), questionnaires, and interviews from 37 older adult participants.
  • Assessed environmental preferences using independent samples t-tests, linear regression models, interaction effect analyses, and EEG topographic mapping.
  • Identified distinct older adult preferences across the evaluated care home environmental dimensions to guide supportive interior architecture.
  • Demonstrated that EEG topographic mapping successfully detects subtle emotional neural responses to environmental attributes that complement self-reported questionnaire data.
