The response to prism deviations in human infants

What is it about?

We found that very young infants could converge their eyes to overcome a base-out prism before the age that signs of binocular vision had been found in the visual cortex previously. We suggested that very young infants either used a more primitive mechanism such as peripheral motor fusion, or even two separate monocular fixation mechanisms which did not depend on binocular vision

Why is it important?

This showed that very young infants had a functioning convergence mechanism before the onset of 3D vision
