Representing relations between individual contributions: when does joint action planning facilitate task performance?
Article in Psychological research, 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
Understanding how individuals plan, predict and adapt their actions is central to understanding the high degree of coordination involved in joint action. While previous research has examined the role of joint action plans in linking individual action representations in a two-person joint action plan, the specific conditions and representations associated with these plans are less well understood. In this study, we investigated when and how joint action plans that specify the relations between individual contributions facilitate performance in a joint task. We hypothesized that joint action plans serve to organize individual contributions to a joint action by specifying the relations between them. Pairs of participants performed a joint computer task that required flipping blocks to produce a joint pattern. We manipulated the availability and information provided by two types of pre-cues: joint cues specified the relation between individual contributions and individual cues specified each participant’s individual part. The results of three experiments showed that information regarding the relation between individual contributions helped co-actors integrate representations of their individual contributions. This is evidenced by faster response times when a joint cue was presented together with a cue specifying the partner’s action. Moreover, joint cues could be used to compensate for the lack of information about individual contributions, as evidenced by faster response times when a joint cue was presented in trials without information about individual contributions. We conclude that joint action plans that specify the relations between individual contributions serve to organize representations of individual contributions and thereby help co-actors infer their own underspecified contribution to a joint action.
