Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

Clinical techniques for visual screening of infants that are not used in routine pediatric examinations include optokinetic nystagmus, preferential looking, and visually evoked potential. Greater use of such techniques might increase success of nonsurgical remedial intervention. (CL)

Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

Relationships between infant visual skills and the development of object permanence and expressive language skills were examined with 31 infants in three groups: visually typical, visually atypical, and Down Syndrome. Measures used to evaluate visual status were: forced preferential looking, optokinetic nystagmus, and behavioral. Object permanence…

Studied infant ability to extract depth information from a three-dimensional structure. Found evidence that 8-month-old infants distinguished between lines indicating edges, and lines indicating markings, and that they are able to use line junctions to perceive line drawings as depicting three-dimensional objects in the picture plane.

Three studies that applied quantitative procedures to measure motor and sensory/motor acquisition among handicapped and nonhandicapped infants and children are presented. In addition, a study concerning the replication of the quantitative procedures for assessing rolling behavior is described in a fourth article. The first study, by C. Janssen,…
