Effects of attentional focus and cognitive loads on cognitive-motor dual-task performance.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundPerforming a cognitive task while maintaining postural control (i.e., cognitive-motor dual-tasking) requires strategic allocation of attentional resources to optimize performance and stability. However, it remains unclear how such attentional strategies modulate dual-task postural control under varying cognitive loads. This study investigated the effects of attentional focus on cognitive-motor dual-task performance across different load levels.
methodsThis study employed a within-subjects factorial design. Fourteen healthy young adults performed a cognitive-motor dual-task involving maintaining a tandem stance while completing a change-detection task requiring detection of orientation changes in visual bars under different load conditions. Participants were instructed to focus on their posture, the cognitive task, or both. Postural performance was measured using sway velocity and 95% prediction ellipse area; cognitive performance was assessed by accuracy and response time.
resultsThe results revealed a significant interaction between cognitive load and attentional focus for accuracy, but not for postural sway or response time. In the high load conditions, lower accuracy was found in the equal-focus condition compared to the cognitive-focus condition. No such differences were observed in the low load conditions.
conclusionsThese findings suggest that the conscious allocation of attention to a visual spatial cognitive working memory task modulates dual‑task performance when the task is difficult (high load) but not when it is easy (low load). This finding highlights the potential role of attentional prioritization strategies in cognitive-motor dual-task performance trade-offs.
