1 · What the graph read from it

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.

2 · The registry

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

Emotional information, and specifically fear-related stimuli, have been shown to be preferentially processed at a nonconscious level and gain privileged access to awareness. However, recent evidence has emerged suggesting these findings are explained by low-level visual features rather than emotional salience. In this study, we tested the hypothesis that emotional salience increases both blindsight (i.e., detection with reduced awareness) and awareness of visually suppressed stimuli. We used fear conditioning to manipulate the emotional significance of neutral expressions presented under Continuous Flash Suppression. Fifty-two healthy participants were presented with perithreshold neutral faces, previously paired with an electric shock (CS+) or not (CS-), and asked to localise the quadrant wherein faces were presented and rate their level of confidence in the response. Results showed fear conditioning strength (indexed by skin conductance response to CS+ versus CS-) was positively associated with both increased "blindsight" and awareness of conditioned stimuli. These findings suggest emotional significance alone, and not merely low-level visual differences, can enhance pre-conscious and conscious processing of visual stimuli.
