The visual perception of relative mass from object collisions.
Article in Journal of vision, 2026. 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
Previous research has shown that observers can make reliable judgments about the relative mass of moving objects that collide in animated displays. One popular explanation of this is that observers' judgments are based on an internal model of Newtonian dynamics. An alternative explanation is that these judgments are based on measurable optical properties that are correlated with relative mass. To better understand this issue, the present investigation reanalyzed the data from three previous studies by Mitko and Fischer (2023), Sanborn et al. (2013), and Todd and Warren (1982), and it replicated an additional study by Hamrick et al. (2016). These new analyses demonstrate that observers' judgments of relative mass are most likely based on the post-collision optical velocities of objects without having to invoke an implausible mental representation of Newtonian dynamics as has been argued by several previous investigators.
