Do infants use cues of saliva-sharing to infer close relationships? A replication of Thomas
Article in Royal Society open science, 2025. 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
Thomas and colleagues found in 2022 that the observation of saliva-sharing between individuals serves as an indicator of relationship thickness for children, toddlers and infants. Our study sought to replicate their crucial experiment (2B), which was conducted online and reported that 8.5- to 10-month-old infants anticipated that a crying individual would be more likely to be comforted by a person who had been observed to share saliva with her than another person who simply had played with her. With the exception of changing the testing environment from online to laboratory, and using an eye-tracker supplemented by manual video coding, we closely followed the methodology of the original study. Our replication resulted in partial success: we replicated looking-time preference for the saliva-sharer but did not replicate the tendency to look first to the saliva-sharer upon observing the puppet's distress. These findings confirm that infants rely on certain behavioural cues for mapping social relationships among third-party individuals.
