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

backgroundRelative deprivation (RD), the belief of being unfairly disadvantaged compared to a standard, has frequently been linked to aggressive behaviors. This study explored how affective experiences are associated with the perception of unfairness (i.e., RD) and, thus, influence aggressive behavior indirectly.

methodsN = 184 participants were randomly assigned to one of two conditions of a game task, in which they experienced either deprivation or no deprivation as the difference between own rewards and the rewards of a fictitious other player. We assessed the subjective perception of RD and affective experiences attributed to the game before measuring aggressive behavior towards the other player in a point subtraction task.

resultsSequential mediation analysis suggested that increases in aggressive affect and decreases in positive affect could be linked to perceiving the game as more unfair for deprived participants, which in turn increased rates of aggressive behavior.

conclusionsAdding to the existing literature, these findings suggest that RD could not only lead to aggression through an affective route but that affective experiences potentially alter perceptions of RD and thus aggressive behavior indirectly.
