The perceptual average in ensemble representation: Neither perceptual nor an average.
Article in Attention, perception & psychophysics, 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
This report targets the claim that gist representations of visual stimuli, called "ensemble averages", are perceptual representations of statistics pertaining to stimuli. We report predictions of a mathematical model based on classical memory architectures which assumes ensemble averages are statistical approximations to stimuli, and that those approximations are constructed within short-term memory. We report results of three new experiments that test those predictions. The results support the memory model and contradict the view that representations of ensemble averages are computed early in perceptual processing via parallel processing or neural pooling, suggesting instead that they are computed via control processes acting on item representations held in visual short-term memory. We conclude that the flight toward new mechanisms that has occurred within the ensemble representation literature is ill-advised, and suggest that one first carefully consider what well-established memory models can accomplish in the ensemble "perception" domain.
