Effects of breeding condition and sound level on tone RS and song |RS| values for monotonic and non-monotonic neurons

	Effect of breeding condition		Effect of sound level		Breeding condition by level interaction
Monotonic
Tone RS	F(1,26) = 6.082	p = 0.021	F(7,26) = 28.14	p < 0.001	F(7,26) = 2.329	p = 0.027
Song |RS|	F(1,14) = 4.879	p = 0.044	F(5,14) = 12.13	p < 0.001	F(5,14) = 3.020	p = 0.016
Non-monotonic
Tone RS	F(1,23) = 5.269	p = 0.031	F(7,23) = 12.01	p < 0.001	F(7,23) = 0.692	p = 0.679
Song |RS|	F(1,16) = 1.087	p = 0.313	F(4,16) = 2.039	p = 0.099	F(4,16) = 1.175	p = 0.330

Four separate two-way (condition by level) mixed-model ANOVAs were performed. Breeding condition was the between-subject measure; sound level was the repeated-subject measure. The values listed in each row are the result of a single ANOVA.
