Figure 6.

Average total grasp error rates per trial by age (A) 5 to 6 years, (B) 7 to 9 years, viewing condition and stereovision. Grasp error rates increased successively between control, stereo+ and stereo nil subjects at ages 5 to 6 years, but were similar in the control and stereo+ participants at ages 7 to 9 years, including generally better performance with binocular compared with monocular vision, whereas there were no differences across views in the older stereo nil subjects. Errors bars: SEMs.
