The purpose of the present study was to examine the recognition of stereograms as a pictorial representation of 3-D shape, while studying prospectively the relationship between sex and stereopsis (visuo-spatial) ability. Twenty-one Mercer University students (9 men, 12 women) viewed 240 random-dot Julesz stereograms at two levels of disparity (hard and easy). The surfaces were displayed using E-Prime software, which also recorded accuracy and reaction time measurements for each surface. Results indicated that there were no significant sex differences for the measures of accuracy or reaction time. The lack of statistically significant effects involving the sex of participants does not support previous research studies that have documented sex differences. Possible explanations, limitations, and additional future research suggestions are discussed.
