Table 5. Effect sizes, unconditional standard errors, confidence intervals and relative importance for parameters included in the top models for the binary response term encoding whether or not players punished their partners for defecting (player did not punish defecting partner = 0, player did punish defecting partner = 1).

Parameter	Effect size	SE	Confidence Interval	Importance
Intercept	-1.81	0.18	(-2.16, -1.47)
Player type (strong)	1.15	0.35	(0.88, 2.22)	1.00
Game type (asymmetric)	0.88	0.19	(0.51, 1.26)	1.00
Player cooperated (yes)	1.29	0.16	(0.97, 1.61)	1.00
Game type x Player cooperated	0.47	0.29	(-0.11, 1.04)	1.00
Player type x Player cooperated	-0.75	0.31	(-1.37, -0.14)	0.65
Player type x Game type	0.16	0.36	(-0.55, 0.87)	0.19
