Effects of training on dynamic stereo acuity performancy by males and females

Dynamic stereo acuity thresholds were obtained for 30 male and female Ss at speeds of rotation of 120 degrees/sec. after pretraining at either O degree, 60 degrees, or 120 degrees/sec. Under conditions of no pretraining females showed significantly larger discrimination errors than males. Pretraining, however, resulted in comparable threshold performance between males and females. Socio-cultural factors responsible for these differences are suggested.
