TABLE 2E.

Post-hoc t-test results for rough-and-tumble play behavior in pairs of juvenile female HET and WT rats.

Pair First play partner	WT-WT	HET-HET	HET-WT	WT-HET
WT	11.1 + 1.8	8.5 + 0.9	11.1 + 1.7	7.9 + 1.3
HET	12.1 + 1.6	14.3 + 1.4	10.6 + 1.7	11.8 + 1.2
t-test	t18 = 0.671, p = 0.511	t18 = 3.343, p = 0.004*	t18 = 0.224, p = 0.825	t18 = 2.202, p = 0.041*

Data are pooled for genotype of the cage mate and are shown as the mean seconds spent interacting per minute + SEM.

*Indicates a significant difference of p < 0.050. Section “3.2.1. Effects of the First Play Partner on Non-Play Social Interactions.”
