Unifying the gestural and the vocal in the evolution of culture, the arts, and the brain.
Article in Frontiers in 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
Cultural evolution in humans is based on the transmission of knowledge and know-how through the process of social learning. Humans have evolved two distinct mechanisms of social learning, although they tend to be discussed in completely separate literatures. They are gestural (or motor) learning and vocal learning. Within the arts, gestural learning is important for the evolution of dance and mime, while vocal learning is important for the evolution of oral literature and vocal music. These two learning systems get jointly recruited to mediate the process of impersonation during theatrical role playing; an actor has to depict both the gestural and vocal features of a portrayed character. An evolutionary synthesis of gestural and vocal learning undergirds the human capacity for culture, including the arts. I discuss potential brain mechanisms for this synthesis in which the neural pathways for the gestural and the vocal may converge.
