The effect of working memory load on interference inhibition in table tennis athletes: the moderating role of motor expertise.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Background: Although the effect of working memory load on interference inhibition has been widely investigated, how the effect manifests in expert athletes remains unclear. Methods: A dual-task paradigm combining an n-back task and a Spatial Stroop task was employed. 20 table tennis athletes and 19 non-athletes were recruited, and event-related potentials (ERPs) and event-related spectral perturbations (ERSPs) were analyzed to examine underlying neural activity patterns. Results: In the Spatial Stroop task, increased working memory load reduced the interference effect on RTs and midfrontal theta power, and was associated with decreased parietal alpha power. Regarding the P300, increased working memory load reduced the interference effect on P300 amplitude in non-athletes. In contrast, the athletes demonstrated a lower interference effect on P300 amplitude and showed no significant impact of working memory load. Conclusion: Increased working memory load reduced the impact of distractors, thereby leading to an overall reduction in the Stroop interference effect. Motor expertise was found to moderate the effect of working memory load on interference inhibition, specifically at the P300 amplitude level. Compared with non-athletes, table tennis athletes exhibited a more efficient and stable pattern of attentional resource allocation under working memory load, this pattern suggests that the moderating role of motor expertise is component-specific. Taken together, the present findings extend existing research on working memory and interference inhibition in athletes and deepen our understanding the relationship between long-term specialized training and brain function.
