Summary

Synesthetic colors in individuals with color-graphemic synesthesia interact with real colors, influencing perceptual grouping in both time and space. This suggests synesthetic experiences are perceptually integrated with external visual stimuli.

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Visual Perception

Background:

  • Color-graphemic synesthesia involves experiencing colors with achromatic alphanumeric characters.
  • Synesthetic colors are perceptually as real as actual colors for non-synesthetes.
  • Investigating interactions between real and synesthetic colors is crucial for understanding perception.

Purpose of the Study:

  • To explore interactions between synesthetic and real colors in perceptual grouping.
  • To determine if synesthetic colors influence grouping over time and space.

Main Methods:

  • Two experiments were conducted with adult color-graphemic synesthetes.
  • Experiment 1 used bistable apparent motion to test temporal grouping.
  • Experiment 2 used binocular rivalry to test spatial grouping.

Main Results:

  • Synesthetic colors of motion tokens interacted with real colors, biasing perceived motion direction.
  • Synesthetic and real colors of characters grouped together, enhancing global dominance in binocular rivalry.

Conclusions:

  • Synesthetic colors substantially interact with real colors in perceptual grouping.
  • These findings highlight the integration of internally generated and externally perceived colors.
