The consequences of color chromaticity on electrophysiological measures of attentional deployment in visual search.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
We investigated to what extent color vividness of visual items influences how humans prioritize information in a search task. For this, color chromaticity was manipulated over two search experiments. While recording the electroencephalogram, participants searched for a shape of certain color among three other shapes, when it emerged from a stream of flickering gray placeholders. Each location was tagged with a specific frequency evoking the steady-state-visual-evoked potential (SSVEP) allowing to track attentional deployment on multiple items. Color vividness boosted SSVEP amplitudes independent of item type, i.e., targets or distractors, while leaving other measures of attentional deployment-event-related potentials and alpha-band amplitudes-mostly unaffected. Interestingly, relative modulation of target and distractor SSVEP amplitudes was comparable between experiments suggesting similar attentional deployment. The results highlight that attentional deployment to search items depends on low-level stimulus features that need to be controlled to allow for inferences about capture or suppression of individual items.
