When required to locate places on outline maps, males consistently perform more accurately than females. This sex difference in geographical knowledge has been observed in samples throughout the United States, in all age ranges examined from the second to the 9th decade of life and in samples differing in average education level from high school to postgraduate degrees. Both males and females appear to acquire geographical knowledge during surface travel through the environment. The information acquired during everyday travel is apparently integrated into topographic representations that comprise a cognitive map. This process is less efficient in females probably because they attend to and remember more about landmarks and less about distance and directional cues than do males. To examine the importance of driving experience on the ability to locate places on an outline map of the Oklahoma City metropolitan area, adolescents who were too young to drive and older persons with varying amounts of experience traveling in the metropolitan area were studied. In the present study the magnitude of the sex difference in accuracy, though not the absolute level of performance, was similar in groups of people too young to drive and in younger and older drivers. Hence, the sex difference in geographical knowledge cannot be the product of differences in driving that may exist between males and females. (JINS, 2002, 8, 804–810.)
