TABLE 2B.

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 t-test
(WT-WT vs. HET-HET)		 HET-WT WT-HET t-test
(HET-WT vs. WT-HET)
Same-genotype 25.1 + 3.1 12.4 + 2.1 t18 = 3.416, p = 0.003* 20.7 + 4.2 22.9 + 3.9 t18 = 1.202, p = 0.245
Opposite-genotype 19.7 + 1.5 23.3 + 1.3 t18 = 1.801, p = 0.088 21.4 + 1.9 19.0 + 2.1 t18 = 0.849, p = 0.407
t-test (same vs. opposite) t18 = 1.581, p = 0.131 t18 = 4.407, p < 0.001* t18 = 0.302, p = 0.766 t18 = 1.595, p = 0.128

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

*Indicates a significant difference of p < 0.050. Section “3.1.1. Effects of the First Play Partner on Rough-and-Tumble Play.”
