Notes. All results are reported as mean ± SEM. For chamber entrances (a), the number of times entering the chamber with the empty cage was subtracted from the entrances into the chamber with the novel mouse. All entrances and exits from chambers also were totaled (c); the SFvF1 mice differed from the FvSF1 mice (F (1,41) = 9.12, p = 0.004) by three-way ANOVA, but there were no significant sex, treatment, or interaction differences. Three-way ANOVA analysis of the chamber entrances indicated a sex difference (F (1,41) = 7.75, p = 0.008) but no treatment differences and no significant interactions. For sniffing (b), the time (s) in direct contact with the novel mouse was measured. Three-way ANOVA analysis of sniffing indicated significant sex (F (1,41) = 14.40, p < 0.001) and treatment (F (1,41) = 9.06, p = 0.004) differences. There were no strain differences or significant interactions.
