Introduction of a Novel Toy Changes the Contingent Dynamics of Infant-Caregiver Joint Exploration.
Article in Developmental science, 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
Infant-caregiver joint exploration is a dynamic process in which dyads coordinate their behaviors. Facing novelty is a critical moment in joint exploration, sparking learning by allowing infants to expand their knowledge and enabling caregivers to support it. However, little research has examined the impacts of novelty on infants' and caregivers' joint exploration. To address this gap, we investigated changes in their real-time contingent dynamics during exploration of novel versus familiar toys. Thirty-nine caregivers and their infants (Mage = 16 months) participated in a 10-min play session at home, consisting of two 5-min phases: a Familiarity Phase and a Novelty Phase, where a novel toy was introduced. A perceptually matched familiar toy was selected for systematic comparison in the Familiarity Phase. Infant exploration and caregiver exploration-promoting strategies (Verbal Promoting, Nonverbal Promoting, Monitoring) were coded at 1-s intervals. Infants were more likely to explore the novel toy following caregivers' exploration-promoting behaviors, particularly when multiple strategies were provided within a short time window. Caregivers maintained similar levels of contingent responsiveness but adopted more observational strategies in response to infants' novel toy exploration, potentially fostering infant-led, autonomous learning. Together, these results underscore the role of novelty in shaping how infant-caregiver dyads coordinate their contingent interactions, and suggest that such moment-to-moment adjustment may foster early learning.
