STEREOACUITY DEVELOPMENT IN INFANTS AND YOUNG CHILDREN

Elise Ciner

Abstract

A new test was developed to assess stereopsis in young children. This test was modified based on the results of previous pilot studies using operant preferential looking and random dot stereograms in toddlers (over 18 months old). The new CSC Test uses a happy face as a stimulus on a homogenous random dot BACKGROUND: Vision screenings were performed on 109 children from 6 to 65 months who were subsequently tested using either an operant (OPL) or forced choice preferential looking (FPL) procedure depending on each child's age, cognitive skills and attentional levels. Stereoacuity levels were obtained using a staircase procedure. Analysis of the data indicates that stereoacuity improves significantly over the first five years of life (F(9.89)=28.5, pBIFOCAL LENSES MAY PREVENT TRANSIENT TASK-INDUCED FAR POINT SHIFTS
