Abstract
Assessment of visual function in human infants and pre-verbal children places the greatest demands upon test efficiency and non-invasiveness. The poor state of development of the behavioral response repertoire and attention span, and the impossibility of communication with the test subject through verbal instructions are each significant obstacles. These difficulties are unfortunately greatest during the critical period for visual development during which the human visual system is the most sensitive to disruption by exogenous factors, and at the same time most receptive to treatment.
