Dependence of brightness induction on the contrast polarity of a disk-annulus stimulus.
Article in Journal of the Optical Society of America. A, Optics, image science, and vision, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Classical theories of brightness and lightness induction have largely been stated in terms of two opposing influences from the surround: contrast and assimilation. In fact, these two effects are part of a more complex but reproducible and mathematically well-defined statistical process in which both low-level neural constraints and top-down cognitive judgments contribute to the measured percept. Here we test a particular model of this process based on edge integration theory with contrast gain control. We employed a brightness matching technique based on disk-annulus stimuli and showed that we can account for our results with a quantitative model in which the contrast polarity of the stimulus plays a critical role.
