FH density was not significantly related to gender, conduct disorder diagnosis, CBCL scores, or other indicators of mood or demography. FH density negatively correlated with maternal years of education (r = −0.25, p = 0.03, see Table 1). Performance on neuropsychological tests and the SWM task did not differ as a function of FH density (see Table 2). Increased age was related to faster reaction time in the vigilance condition (r = −0.31, p = 0.01) and to better accuracy in SWM (r = 0.28, p = 0.02) and vigilance conditions (r = 0.28, p = 0.02). Pubertal development scores indicated that, on average, males were nearly at mid-puberty, while females were between mid- to late puberty. Pubertal development was not related to SWM task performance or neuropsychological test scores (ps > 0.05).
