Cognitive experience design: the effect of luminance change of central light on perceived time

ABSTRACT:

This study aims to examine the effects of luminance contrast on cognitive experience. An experiment was conducted under controlled conditions with high/low luminance contrast settings. Perceived time was measured by tapping rate, while subjective ratings of astonishment, concentration, comfort, and a semi-structured interview were collected. The results showed that higher luminance contrast elicited greater astonishment, and perceived time was associated with concentration and comfort but limited with astonishment, suggesting that astonishment may involve higher-order cognitive reappraisal.
