	N	Age	IQ	N	Age	IQ
Total sample	34	13.36 (1.52)	116.89 (10.89)	55	15.96 (1.61)	113.29 (9.41)
Males	27	13.45 (1.61)	117.22 (10.21)	21	16.47 (1.38)	113.81 (10.77)
Females	7	13.10 (1.24)	115.29 (15.29)	34	15.65 (1.68)	112.97 (8.62)

Note: Values represent means and standard deviations. Overall, pubertal groups differed in age, F(1, 87) = 56.01, p < .000, but not IQ, F(1,87) = 2.56, p > .05. Similar patterns held for each sex. Early-to-mid pubertal males and females were similar in age and IQ. In late puberty, males were marginally older, F(1,53) = 3.46, p = .07.
