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

The goal of the study was to investigate temporal dynamics of excessive violent game playing. We compared behavioral data and event-related potentials (ERPs) of excessive video game players (EVGPs, n = 21) and non-players (NPs, n = 21) using a classical learning, cued recall and recognition paradigm, featuring violent and non-violent words. During the recognition phase, EVGPs performed better for violent words, but worse for non-violent words compared to NPs. Also, EVGPs showed slower reaction times than NPs when responding to new violent words. We found significant group differences in parietal P300 and FN400 amplitudes. The EVGP group showed larger P300 amplitudes for violent words, and more negative FN400 amplitudes for new violent words compared to NPs. The results imply that EVGPs differ from NPs in their cognitive and ERP responses to violent and non-violent verbal stimuli. The cognitive processes of EVGPs are consistent with a model of attention and memory bias rather than with desensitization to violence.
