Venturing into novel terrain poses physical risks to a female and her offspring. Females have a greater tendency to avoid physical harm, while males tend to have larger range sizes and often outperform females in navigation-related tasks. Given this backdrop, we expected that females would explore a novel environment with more caution than males, and that more-cautious exploration would negatively affect navigation performance. Participants explored a novel, large-scale, virtual environment in search of five objects, pointed in the direction of each (...) object from the origin, and then navigated back to the objects. We found that females demonstrated more caution while exploring as reflected in the increased amounts of pausing and revisiting of previously traversed locations. In addition, more pausing and revisiting behaviors led to degradation in navigation performance. Finally, individual levels of trait harm avoidance were positively associated with the amount of revisiting behavior during exploration. These findings support the idea that the fitness costs associated with long-distance travel may encourage females to take a more cautious approach to spatial exploration, and that this caution may partially explain the sex differences in navigation performance.

Spatial experience in childhood is a factor in the development of spatial abilities. In this study, we assessed whether American and Faroese participants’ (N = 246, Mage = 19.31 years, 151 females) early spatial experience and adult spatial outcomes differed by gender and culture, and if early experience was related to adult performance and behavior. Participants completed retrospective reports on their childhood spatial experience, both large-scale (permitted childhood range size) and small-scale (Lego play). They also completed assessments of their current (...) large-scale spatial behavior (navigational strategy) and small-scale ability (mental rotation task, MRT). We replicated earlier results showing better MRT performance among males and more reliance by males on orientation navigational strategies, although males and females reported similar ranges as children. However, there were cross-cultural differences, with Faroese having larger childhood ranges, less reliance on route strategies, better MRT scores, and a smaller gender difference in MRT. Larger permitted childhood ranges were associated with reduced use of route strategies for navigation in adulthood, and greater Lego play in childhood predicted better MRT performance as adults. There was also some evidence supporting relationships across spatial scales, with more Lego play predicting an orientation style of navigation and larger childhood ranges predicting better performance on the MRT, although the latter was not independent of country. In sum, we observed an association in both cultures between large-scale childhood experience and large-scale behavior in adulthood, small-scale experience in childhood and adult small-scale performance, and some associations between experience and behavior across spatial scales.
