Figure 4.

Predictability (reverse signed entropy) of infant and mother actions in multiple contexts. Dyadic states representing infant (on the left) and mother (on the right) smile initiations and terminations are presented in the top set of graphs. Dyadic states representing infant gaze shifting (on the left) and mother smiling (on the right) are presented in the bottom set of graphs. Each panel describes the predictability of a given infant or mother action (e.g., infant smile initiation while mother is not smiling in the hand panel of the top left graph) both when the infant acted most recently (infant last) and when the mother acted most recently (mother last). Predictability is described with respect to infant age categories: 4 – 10 weeks (1–2.5 months), 11–17 weeks (2.5 – 4 months), and 18 – 24 weeks (4.5 – 6 months).
