{"pk":50360,"title":"Triadic comparisons reveal representational motifs in human color perception.","subtitle":null,"abstract":"While individual differences have been found in many aspects of color perception, it is unclear whether mental representations of color vary between individuals in a structured way. To test for structured variability, we collected perceptual similarity judgments for 58 colors in a triadic-comparisons procedure, and from each participant's judgments, embedded the colors into a personalized three-dimensional space. The personalized embedding predicted a participant's similarity judgments on held-out items significantly better than did (a) embeddings from other participants, suggesting reliable individual differences in perceived color similarity (p < 0.0001), and (b) color coordinates in a standardized perceptual color space (CIELAB; p < 0.0005). Across individuals, embedding structure did not vary randomly but fell into two clusters, one encompassing more distinct color categories and the other a more continuous perceptual space. The results suggest the existence of previously unrecognized \"motifs\" in how people represent colors.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Psychology; Concepts and categories; Perception; Representation; Vision"}],"section":"Member Abstracts with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/675702mb","frozenauthors":[{"first_name":"Clementine","middle_name":"","last_name":"Zimnicki","name_suffix":"","institution":"University of Wisconsin-Madison","department":""},{"first_name":"Timothy","middle_name":"T","last_name":"Rogers","name_suffix":"","institution":"University of Wisconsin- Madison","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/50360/galley/38322/download/"}]}
