Table 1. Effect sizes and P-values for significant terms in each model for the Development experiment (for specific P-values see text).

Development experiment			Day 1 predictors					Day 2 predictors		Genotype effects
Model	Question	Response variable	Preferred or unpreferred	Group size	Focal male aggression	Stimulus male attacks on focal day 1	Focal male presence on patch day 1	Stimulus male attacks on focal day 2	Focal male presence on patch day 2	Effects of focal male genotype: direct or indirect genetic effects
1	Do preference and/or aggression determine social experience?	Stimulus males attacks on focal day 1	0.34*	NS	0.052*		NS (P=0.051)	NA	NA	Indirect genetic effect*
2	Is focal male experience caused by focal male aggression?	Focal male aggression day 1	NS	NS		0.18**	NA	NA	NA	Direct genetic effect**
3	Does experience affect behavioral development?	Focal male aggression day 2	NS	NS	NS	−0.18*	NA	−0.15*	0.0002*	Direct genetic effect*
