Note. All values were controlled for chronological age. Means and standard deviations within each row with no subscript in common significantly differ statistically. Subscripts “a” and “b” refer to main effects of the sex variable, and subscripts “c” and “d” refer to main effects of the experimental conditions.
+
indicates that the main effect of experimental condition approached significance (p = .06).
