Toddlers' visual exploration during decisions predicts uncertainty monitoring 1 year later

The longitudinal relation between toddlers' behaviors in uncertain situations (e.g., information seeking, hesitation) and preschoolers' uncertainty monitoring was investigated (between 2014 and 2019 in Northern California; Time 1: N = 183, M = 28.99 months, 53% female, 67.8% White; Time 2: N = 159, M = 41.64 months, 52.2% female). Eye movements and response latencies were recorded as children identified a target from two partially occluded (Time 1) or degraded (Time 2) images. Confidence ratings for identifications were collected at Time 2. At Time 1, gaze transitions between response options, but not response latencies and mental state language, predicted Time 2 uncertainty monitoring. Overall, these findings provide the first direct evidence of connections between toddlers' uncertainty behaviors and preschoolers' uncertainty monitoring.
