The article points out the importance of deciding what kind of perceptual problem a child has and providing the appropriate kind of perceptual motor program. (CD)

The early linguistic environment of normal infants and children is discussed and research is applied to children who have severe and profound handicaps. (BD)

Fifty-two educable mentally retarded children (8-14 years old) were randomly assigned to either a visual-spatial training condition or a control group. (Author)

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

It is proposed here that adults process orientation information at different levels and that these levels correspond to developmental stages in the coding of orientation in childhood. (Author)

Subjects in three age groups (N=96) who resided at home were tested on appreciation and comprehension of 12 conservation and 12 nonconservation jokes. Cognitive perceptual theory of humor applies in old age as in childhood, with appreciation depending on a match between ability level and cognitive demand of the joke. (Author)

Focused and divided auditory attention were studied in 7- and 10-year-old children. (BD)

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)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

To test the tendency of subjects to perceptually organize discrete temporal patterns with regard to runs of identical stimulus events, spatiotemporal patterns of white noise were presented for reproduction. It is suggested that changes in runs of auditory patterns are perceptually analogous to changes in contours of visual patterns. (Editor/RK)

Perceptual decentering was examined in 30 nonretarded children, 30 educable mentally retarded (EMR) children equated for CA, and 30 EMR children equated for MA. (Author)

A total of 180 6-, 8-, and 10-year-old children participated in tasks employing an object array in which the views from the experimental positions were objectively of equal difficulty. (SB)

Two approaches to auditory training for improved speech recognition using 20 adults with mild to moderate sensorineural hearing impairments were compared. No significant differences were found between group one which spent training time on activities involving sentence perception and perceptual strategy and group two which focused on consonant…
