Comparing color qualia structures through a similarity task in young children versus adults.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Examination of the subjective qualitative aspects of an experience, or "qualia" in short, is a fundamental and core aspect of consciousness research. How can we characterize the particular quality of redness, i.e. a red quale? Based on a recent proposal of the structural characterization of qualia, which did not rely on verbal descriptions, we developed a task that obtained pairwise similarity judgments at four graded levels, with easy and intuitive visual interfaces designed to engage young children. We examined color qualia structures in children (3 to 12-y-old in Japan and 6 to 8-y-old in China) and compared these with those of Japanese adults. Approximately half of the assessed 3-y-old children completed the experiment via our touch panel device version of the task and had reliable responses. Despite known developmental and/or cultural effects of color term usage, we found that color qualia structures were quite similar across the age groups and cultures. Our finding supports the view that color qualia structures emerge early. We also observed age-related differences in the evaluations of some color pairs, which implied subtle changes in the structures behind color experience.
