Sex Differences in Accuracy and Precision When Judging Time to Arrival: Data from Two Internet Studies

Abstract  

We report two Internet studies that investigated sex differences in the accuracy and precision of judging time to arrival.
We used accuracy to mean the ability to match the actual time to arrival and precision to mean the consistency with which each participant made their judgments. Our task was presented as a computer game in which
a toy UFO moved obliquely towards the participant through a virtual three-dimensional space on route to a docking station.
The UFO disappeared before docking and participants pressed their space bar at the precise moment they thought the UFO would
have docked. Study 1 showed it was possible to conduct quantitative studies of spatiotemporal judgments in virtual reality
via the Internet and confirmed reports that men are more accurate because women underestimate, but found no difference in
precision measured as intra-participant variation. Study 2 repeated Study 1 with five additional presentations of one condition
to provide a better measure of precision. Again, men were more accurate than women but there were no sex differences in precision.
However, within the coincidence-anticipation timing (CAT) literature, of those studies that report sex differences, a majority
found that males are both more accurate and more precise than females. Noting that many CAT studies report no sex differences,
we discuss appropriate interpretations of such null findings. While acknowledging that CAT performance may be influenced by
experience we suggest that the sex difference may have originated among our ancestors with the evolutionary selection of men
for hunting and women for gathering.
