Figure 4.

Participation in the enrichment task (i.e., proportion of scans that an individual interacted with the enrichment device in an enrichment session) as a function of time (i.e., enrichment session number) during the treatment phase. Circles represent individual responses in each enrichment session, in the morning (in black) and in the afternoon (in grey). The dashed black line represents the fitted model, which is like Model 1 but unconditional on all the other predictors that were standardized. Data were jittered horizontally to avoid overplotting.
