Differences in total number of calls (n = 42): (a) There were significant differences according to the prenatal treatment received, with control group (CNT) (n = 14) being significantly different from the other two groups: Chlorpyrifos (CPF) (n = 14) and valproic acid (VPA) (n = 14); (b) There was a significant difference between males (n = 21) and females (n = 21); (c) There was no significant Treatment * Sex interaction, in spite of the fact that the males of the CNT (n = 7) group tend to emit considerably more calls than any other group (CNT female n = 7; CPF male n = 7; CPF female n = 7; VPA male n = 7; VPA female n = 7), showing more clearly the how the prenatal treatments differentially affect males and females.
