Prior morphological and anthropological work indicates that there are two "sexes" ("females" and "males") in the terrestrial species, Homo sapiens and raises the possibility that one of these ("females") engages in substantial internal information processing process ("thinking"), while the other ("males") does not. In the present studies, we have tested this hypothesis by comparing in populations of human females and males the time to complete several different tasks. Am important assumption of this study is that some tasks require more internal information processing than others, and that such differences would be apparent in longer times to complete those tasks which require more internal information processing. Our findings indicate that, with some reservations, this assumption is appropriate. With this issue resolved, our findings fail to support the hypothesis that males differ from females in an absence of substantial internal information processing. Further research will be needed to determine whether the particular populations sampled in this study are representative of the species as a whole.
