This preregistered study (N = 250; 148 women; after exclusions) aimed at replicating findings by Kollner and Bleck (2020) regarding relationships of the implicit power motive (nPower) and activity inhibition with their proposed new marker of pubertal organizational hormone effects, the ulna-to-fibula ratio (UFR). Our cross-sectional design included the Picture-Story Exercise (nPower, activity inhibition) and anthropometry of ulna and fibula length, facial width and height, shoulder/waist/hip circumference, and 2D:4D digit ratio. As a validation check for organizational hormone effects' relationships to motivation, we tested UFR's sex-dimorphism, independence of body height, and interrelationships with other markers. Results showed that the validation check was successful. UFR was sex-dimorphic, independent of body height, and significantly associated with other possible markers of pubertal organizational hormone effects, including facial width-to-height ratio, waist-to-hip ratio, and shoulder-to-hip ratio. As predicted, a "sex-typical" UFR, low for women and high for men, was associated with the inhibited power motive (outliers excluded). nPower's sex-dimorphic relationship with UFR reported by Kollner and Bleck (2020) was not replicated. UFR's relationship with the inhibited power motive, in conjunction with findings by Schultheiss et al. (2019) for prenatal organizational hormone effects, add to accumulating first evidence for hormonal contributions to implicit motive development but also call for larger-sample replication.
