Audience presence influences cognitive task performance in chimpanzees.
Article in iScience, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Human cognitive performance can be significantly influenced by the presence of audience members. While often associated with reputation management, which is considered uniquely human, it is unclear to what degree this phenomenon is shared with non-human animals. To investigate such audience effects in chimpanzees, we recorded the performance of six chimpanzees on three different numerical touch screen tasks varying in difficulty and cognitive demand, in the presence of variable audience member compositions over six years. Our results indicated that chimpanzee performance was influenced by the number and types of audience present. Performance increased for the most difficult task as the experimenter count increased, while for the easiest task, performance decreased as familiar audience and experimenter count increased. This suggests that audience effects on cognitive processing can be found in chimpanzees and that the evolutionary roots of this trait may date back to before the development of reputation-based normative societies in humans.
