Specified functions of the first two fixations in face recognition: Sampling the general-to-specific facial information.
Article in iScience, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Visual perception is enacted and constrained by the constantly moving eyes. Although it is well known that the first two fixations are crucial for face recognition, the function of each fixation remains unspecified. Here we demonstrate a central-to-divergent pattern of the two fixations and specify their functions: Fix I clustered along the nose bridge to cover the broad facial information; Fix II diverged to eyes, nostrils, and lips to get the local information. Fix II correlated more than Fix I with the differentiating information between faces and contributed more to recognition responses. While face categories can be significantly discriminated by Fix II's but not Fix I's patterns alone, the combined patterns of the two yield better discrimination. Our results suggest a functional division and collaboration of the two fixations in sampling the general-to-specific facial information and add to understanding visual perception as an active process undertaken by structural motor programs.
