Can gestures speak louder than words? The effect of gestural discourse markers on discourse expectations.
Article in Discourse processes, 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
Much of the research on discourse marking has focused on written text, thereby not considering signals available in the multimodal domain. It is therefore an open question to what extent comprehenders rely on nonlexical discourse signals, such as gestural discourse markers. We conducted a multimodal continuation study: 48 participants were presented with videos of a speaker narrating short stories including a contrast, a list, or an exception relation. In one condition, the target discourse relation was accompanied by a gestural discourse marker; in another condition it was not. The sound was cut out at the second relational argument, and participants were asked to provide a likely continuation. The results showed that comprehenders can infer discourse meaning from gestures, but gestural signals are not as strong as lexical connectives have been found to be. These findings contribute to our understanding of how people can achieve successful comprehension in multimodal communication.
