Table 5.

Model comparison summary statistics for two sets of GLMMs. Sex = Sex of demonstrator. 1|ID = Random intercepts for individual. Sex|ID = random slopes and intercepts for Individual. K = number of effective parameters.

GLMM Set 1: Audience = Number of individuals < 3m from demonstrator
Model	K	AICc	Delta AICc	Total AICc weight
Audience ~ 1|ID	3	9178.19	0	0.94
Audience ~ Sex + Sex|ID	6	9183.63	5.44	0.06
GLMM Set 2: Audience = Proportion of group < 3m from demonstrator
Model	K	AICc	Delta AICc	Total AICc weight
Audience ~ 1|ID	3	−2114.53	0	0.94
Audience ~ Sex + Sex|ID	6	−2108.95	5.58	0.06
