“…Although our study showed highly reliable sex differences in both the new virtual DMP task and the mental rotation test, with male participants performing on average better than female participants, the potential biological, psychological, and social/environmental factors underlying these sex differences (Baenninger & Newcombe, 1995;Hirnstein, Coloma Andrews, & Hausmann, 2014;Levine, Vasilyeva, Lourenco, Newcombe, & Huttenlocher, 2005;Padilla et al, 2017;Picucci, Caffò, & Bosco, 2011) remain largely to be clarified. For example, while organizational and activational effects of the male sex hormone testosterone have been implicated in male advantages in mental rotation and place learning performance in virtual maze tasks (see reviews in Hirnstein et al, 2014;Nowak, Diamond, Land, & Moffat, 2014), it has also been demonstrated that gender stereotypes and whether testing took place in mixed-or same-sex groups can affect cognitive sex differences, including in mental rotation (Hirnstein et al, 2014), and that "navigation" experience (as measured by how many of a list of local and national places participants had visited) affects sex differences in incremental place learning on a watermaze analogue (Padilla et al, 2017).…”
