Of the 200 subjects enrolled, eight women were excluded from analyses due to current hormone therapy use; four subjects were excluded due to excessive head motion (>15% motion outliers), and two subjects did not complete the functional scans due to claustrophobia, producing a final sample of 186. Parental socioeconomic status (SES) was a composite index of family income, education, and occupation and ranged from 1.0 (low) to 9.3 (high). Verbal IQ was estimated from the American National Adult Reading Test (Nelson, 1982). Pre, Premenopausal; Peri, perimenopausal; Post, postmenopausal.
