We aimed at replicating findings reported by Schultheiss et al. (2003) on the associations between gonadal steroid hormones and implicit motives across the menstrual cycle. We tested whether the implicit needs for affiliation (n Affiliation) and power (n Power) covary with salivary estradiol, testosterone, and progesterone. Our longitudinal study (N = 131, 49 men, 50 normally cycling women, 32 women taking hormonal contraception) with three assessments, corresponding to the follicular, periovulatory, and luteal phases of the cycle, included the Picture-Story Exercise (n Power, n Affiliation), saliva collection, and radioimmunoassays (estradiol, testosterone, and progesterone). Multilevel analyses revealed that even though most of the expected hormonal characteristics were observable in our sample, none of the previously reported motive–hormone associations were fully replicated, except for testosterone positively covarying with n Power in men. Contrary to our hypotheses, the association between progesterone and n Affiliation in men was positive. We observed a difference in n Power in women depending on relationship status, but it was not associated with estradiol. This is the first longitudinal study attempting to replicate findings reported by Schultheiss et al. (2003). Our results are based on a larger sample, sensitive and valid assays, and we were not able to replicate most of the previously reported associations.
