Testosterone, Men, Women, and Mental Rotation

Various studies have shown that in general, men fare better than the ladies on spatial rotation tasks. Here Kossalyn's group takes a stab at seeing whether salivary testosterone levels could account for better performances. The results were a bit surprising. This was clearly exploratory work, but the higher 'T' subjects apparently had lower error rates and faster responses, suggesting the possibility that greater precision and speed of decision making, rather than spatial ability accounted for the differences.
