Role of long-term memory in object-based attention for the maintenance of binding in visual working memory.
Article in Frontiers in psychology, 2025. 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
Background: Past research has suggested that binding retention requires more object-based attention than feature retention in visual working memory (VWM). Long-term memory (LTM) is also believed to contribute to VWM. Objectives: We investigated whether LTM reduces the object-based attention required to maintain bindings. Methods: Participants were familiarized with specific items prior to the VWM task to establish LTM representations, and we included a Duncan task in the maintenance phase of the VWM task to consume object-based attention. Results: Results revealed that consuming object-based attention disproportionately impaired bindings compared to features for unfamiliar objects but not for familiar ones (Experiment 1). This effect could not be attributed to differences in memory set sizes between the familiar-objects condition and the unfamiliar-objects condition (Experiment 2) or to differences among participants between the two levels of the LTM condition (Experiment 3). Conclusion: These findings demonstrate that LTM availability modulates the role of object-based attention in retaining bindings in VWM, with bindings requiring more object-based attention than individual features for unfamiliar objects but not for familiar objects.
