Table 4.

Mixed effects models of N = 84 dyads in five interaction conditions. Dependent variable, nonverbal synchrony.

	Model a (n = 420)	Model b (n = 420)
Fixed Effects
PANAS positive before	t = -0.16
PANAS positive after	t = 2.52*
PANAS negative before		t = 0.08
PANAS negative after		t = -1.98*
Random Effect
Dyad (% variance)	6.30	5.72
Whole model variance (%)	12.66	11.15
AIC	-1705.9	-1705.3

For both models, fixed effects estimates, the random effect estimate, whole model variance, and AIC are listed (top to bottom). AIC, Akaike’s Information Criterion; PANAS, Positive and Negative Affect Scale. *p< 0.05.
