The assessment of vision as it relates to and interacts with motor development is reviewed. The focus is on eye readiness skills normally occuring in infants' first few months of life and preceding eye-hand coordination. These visual skills fall into three categories: fixation, tracking, and scanning. Six standardized scales are reviewed and results are reported: Gesell's Developmental Schedules, Bayley Scales of Infant Development, Denver Developmental Screening Test, Cattell Infant Intelligence Tests, Griffiths Mental Development Scale, and Buhler's Test of the First Year of Life. The scales were developed from normative data collected on children ranging in age from birth to six years. Control variables were: sex, race, residence, and education of the head of household. The reliability coefficients included in the scales were split half, test-retest, and tester-observer. Several non-standardized assessment instruments and checklists for use with normal or handicapped children list the developmental sequences and ages at which certain skills emerge; other instruments list visual behaviors along with general descriptions of measurement techniques and definitions of acceptable responses. An overview of research on basic visual capacities of infants is outlined. (Author/GK)
