Linear mixed model fit indices for models of interest.

Model	AIC	BIC	Log likelihood	χ2	χ2 difference	df	p
Model 1	16,237	16,302	−8,109	16,217
Model 2a	16,233	16,304	−8,106	16,211	5.72	1	.02*
Model 2b	16,238	16,309	−8,108	16,216	0.58	1	.44
Model 2c	16,239	16,310	−8,109	16,217	0.006	1	.94
Model 2d	16,238	16,309	−8,108	16,216	1.37	1	.24

Note. Model 1 included main effects for leading rate and each of the four predictive factors. Each remaining model was compared to Model 1 on an individual basis. Model 2a included an interaction between leading rate and rhythm perception. Model 2b included an interaction between leading rate and gender. Model 2c included an interaction between leading rate and social competence. Model 2d included an interaction between leading rate and partner familiarity. AIC = Akaike information criterion; BIC = Bayesian information criterion; df = degrees of freedom. Boldface text represents best-fitting model.
