Data are reported as means (SE) adjusted for day of week (EMA and diary) and time of day (EMA only). d = Cohen’s d effect size estimate.
*n = 57 in diary analyses.
P < 0.05.
Means calculated from estimated number of social interactions; time × condition differences and effect sizes calculated from raw data (Measures).
