Does Physical Interaction with Insight Problems Really Affect the Solution Rate?
Article in Journal of Intelligence, 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
Insight problems are traditionally presented in verbal or visual form; however, some research suggests that physically interacting with the problem materials may facilitate insight problem solving. In contrast, the more recent literature found no performance improvement with manipulable materials, except for spatial problems (e.g., the "Eight Coins problem"). In Experiment 1, to challenge the hypothesis that the facilitating effect of material manipulation is mainly related to spatial insight problems, two groups of participants were presented with another spatial insight problem, the "Pencil problem" (a new version of the traditional "Match problem"), either in paper format or in a physical interactive condition. The results showed no significant differences in success rates based on presentation format. Therefore, manipulating the materials does not appear to facilitate solving spatial insight problems
