Note. Intensity of approach, avoidance and vocal expression in Scary Mask, intensity of avoidance in Storytelling, and speed and intensity of vocal sadness in Not Sharing, were coded but not included in episode-level composites due to low correlations with other parameters. Facial intensity was coded in Storytelling but not included due to low frequency of responses above 0. No sadness composite was formed for Transparent Box due to low frequency of responses above 0. Square-root transformations were applied to parameters with skewness > 2.00 or kurtosis > 7.00. Parameters were standardized using z-score transformations, and unit-weighted mean composites were formed. s = seconds.
