To examine the relationship between performance on the Frostig Developmental Test of Visual Perception and birth order, 578 first-graders were tested. (Author)

The effects of perceptual and cognitive factors on information processing in visual periphery were studied in 5- and 8-year-old children and in adults. Subjects judged either the similarity (Study 1) or identity (Study 2) of geometric forms. (Author/SB)

This experiment was designed to determine whether children's inability to discriminate mirror-image oblique lines is a function of encoding in memory the left-right orientation or the degree of slope of an oblique line. (Author/SB)

A series of six experiments compares young children's competence in attributing absence of knowledge (ignorance) to their competence in attributing a false belief to the other. (HOD)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

A review of the ophthalmologic, optometric, and psychological literature relating to the assumption that a relationship exists between reading failure and perceptual ability has found no evidence to support this assumption. (CL)

Infants at two age levels were shown six patterns which represented three levels of stimulus complexity and two types of organization, facial and nonfacial. Results agree with previous studies in suggesting a change between ages 10 and 15 weeks in dimensions which underlie infants' response to facelike patterns. (Author/HS)

The development of space awareness should facilitate effective playing and coaching through increased ability to observe spatial arrangements as they apply to game strategy. (JD)

Suggests a connection between the perceptual world taken as a system of signs and the system of signs we normally think of as visible language and defends this thesis. (TO)

Results of this study suggest that 3-year-olds have a good deal of sensitivity to static depth information. (Authors)

Although Ss underestimated the size of the illusion in the predicted direction, no significant correlations between size of illusion and either age or IQ were found. (Authors)

An argument centered on perceptual-motor training as an educational fad and a criticism of training approaches. Paper presented at the annual meeting of the American Orthopsychiatric Association (New York, New York, 1969). (RJ)

Argues that visuals constitute a language" in that they suggest physical objects . . . just as words signify their referents;" an adaptation of a paper presented at national convention of Department of Audiovisual Instruction, YNational Education AssociationI (Houston, Texas, March 28, 1968). (Editor/RD)

The results suggested that profoundly retarded children do show habituation and dishabituation to visual stimuli and are actively storing and processing information about their perceptual world. (Author/DLS)
