The Guidance of Attentional Selectivity in Visual Search Is Always Feature-Based: Behavioral and Electrophysiological Evidence From Feature and Conjunction Search Tasks.
Article in Psychophysiology, 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
It is generally assumed that the guidance of attention in visual search operates in a feature-based fashion, but this conclusion is mainly based on the results of search tasks with feature-defined targets. Here, we investigated whether attentional templates may contain integrated object-based representations in tasks where targets are defined by feature conjunctions. Attentional load was manipulated by instructing participants to search for a single or one of two different possible targets. Search targets were either defined by a particular color or shape (feature search tasks) or by a color/shape combination (conjunction search task), and load effects were compared between these two types of tasks. Load effects on search performance as well as on electrophysiological markers of attentional guidance (N2pc components) and the number of attentional templates activated in working memory (CDA components) were much more pronounced during conjunction search. This suggests that attentional templates are always feature-based, even when object-based templates are in principle available to reduce memory load.
