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

backgroundThe attentional boost effect refers to enhanced memory for information presented concurrently with target detection. This study explored the temporal neural dynamics of attentional boost effect during encoding and recognition to clarify whether it results from target enhancement or distractor inhibition.

methodsA dual-task paradigm combining digit detection with word memorization was employed. Electroencephalography was recorded throughout the encoding and recognition stages. Event-related potential components, including P1, N1, P2, N2, P3, FN400, and late positive component (LPC), were analyzed across four regions of interest to track the time course of neural processing associated with attentional facilitation.

resultsRecognition accuracy for target-associated words was significantly higher than for baseline and distractor words, confirming a robust attentional boost effect. Event-related potential analyses revealed that during the encoding stage, target words elicited shorter P2/N2 latencies and larger P3 amplitudes. During the recognition stage, target words evoked more positive FN400 and LPC responses relative to new words.

conclusionsThe attentional boost effect emerges from the combined operation of target enhancement and distractor inhibition. These findings outline the neural timeline of attentional boost effect and provide insights for developing cognitive enhancement and rehabilitation strategies.
