Fig 1.
The estimated size of the prediction error (and pupil dilation thereof) for the two experimental conditions as predicted by the computational models, based on Hypothesis 1 (A), Hypothesis 2 (B), and Hypothesis 3 (C).

Snapshots from stimulus movies of the (A) Familiarization, (B) Minority-first condition, and (C) Majority-first condition.
Fig 3.
Average change in pupil size as compared to a fixed baseline period in Minority-first (black line) and Majority-first (gray line) conditions over the course of trials in 24-month-olds.
Error bars represent SEMs.
