Several researches suggest that males tend to show a drive to systemize while females tend to show drive to empathize. We examined whether a bipolarized dimension of emphasizing vs. systemizing (E-S) is reflected on the performance of random number generation (RNG). Although number system is a typical example of systemizing, random production of numbers requires to suppress, or to control, the sequence of numbers, which is represented in our cognitive processing, the task of the RNG does not need systemizing. Stereotyped response pattern in the RNG reflected the difference of the E-S (D-score), and it is closely similar to that of male-female (MF) in the form of the first-order matrix of number pairs. By using the MF matrix as an axis, MF axis value showed a small correlation with D score (r=0.21), but a strong correlation with ES axis value (r=0.80).
