title: Assessment of vision in young children: a new operant approach yields estimates of acuity.
abstract: Behavorial assessment of visual function is now possible in 6- to 24-month-old children through the use of an operant preferential looking technique. Use of the technique to measure grating acuity shows that acuity develops from 6 to 8 min arc at 6 months of age to near adult levels by 2 years.
