The relation between Matching Familiar Figures Test performance and Piaget's construct of perceptual activity was examined with 48 third- and fourth-grade boys. (SB)

Specifically language-impaired (SLI) children (N=35) were compared with a matched group of 36 non-SLI Ss on tests of speech perception and language ability. Follow-up results indicated that perceptual development occurred in both groups of children. (Author/CL)

Results failed to replicate previous findings of a temporal processing deficit specific to the auditory modality in LI children. Further analyses resolved this apparent conflict between the present and earlier studies by demonstrating that age is an important variable underlying modality specificity of perceptual performance in LI children.…

Investigated the development of classificatory organization. Two experiments examined age differences in children's spontaneous extensions of a classification and a third examined children's extensions under hypothesis-testing instructions. (JMB)

The hypothesis that perceptual development proceeds from less to greater dimensional separability was tested by giving a speeded classification task to first and fourth graders. Results supported the hypothesis that development proceeds toward greater flexibility of attention rather than simply toward increasing separability. (Author/DB)

To assess the development of monocular slant perception as well as the relative effectiveness of different sources of information, 90 children in first, third, and fifth grades and 30 college adults were asked to make judgments of surface slant on the basis of monocular texture gradient information. (Author/JH)

Twenty-four subjects at each of four grade levels (first, third, fifth, and college) made judgments of physical slant of surfaces with three levels of variability. Absolute error of judgment decreased with age, but texture variability had no effect at any grade level. (JH)

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)

This study examined whether the perceptual weights of 40 children and adults with hearing loss differ from those of normal hearing counterparts. Results revealed child-adult differences in overall performance and also revealed an effect of hearing loss. However, the pattern of perceptual weights was similar across groups under most conditions.…

One hundred and sixty subjects ages 7, 9, 11 and 21 years judged the standard Brentano form and a dot form of the illusion of 5 trials at 30 second intervals. (LLK)

Six experiments assessed young children's spatial orientation relative to their imagined surroundings. The experiments found that children as young as 3.5 years were able, like adults, to accurately walk along a path that replicated the route between their seat and the teacher's desk in their preschool classroom. (MDM)

A total of 416 elementary school children described in writing what their grandparents meant to them. Girls were more likely than boys to mention love. Younger children reported obtaining more affective provisions (e.g., attachment and nurturance) from grandparents while older children reported more cognitive provisions (e.g., guidance and pride…

A total of 259 children between 5 and 12 years of age plotted the location and heading of an adult who was standing in their classroom onto a map of the classroom. Older children performed better than younger ones; boys performed better than girls. (MDM)

Second and third graders and fifth and sixth graders were tested in a very large, unfamiliar environment to determine the relation of their knowledge of an abstract reference frame to performance on a spatial inference task. (HOD)
