Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)

Identifies the principle types of cognitive and affective influences which contribute to the development of an individual's conceptual framework. Explains how external influences affect a child's interpretation of the environment. Urges that multidimensional experiences be offered to children and that students' perceptual levels, personal…

This study was undertaken to determine the relative contribution of age, sex, and three stimulus features (board shape, block arrangement, and block shape) to perceptual accuracy on 39 board/block adaptations of Piaget's three-mountain task. (Author/SB)

Examines the effect of different training methods on perceptual learning of impulsive children. A matching to sample method (M), and a differentiation method (D) were used. Data indicated that Ss receiving D training learned to process features distinguishing stimuli; whereas, Ss receiving M training showed no preference for a particular mode of…

Subjects were Zambian elementary school children, ages 7-17, providing evidence of weight conservation behavior and those who did not; principal dependent variable was performance on locally-developed psychometric measures of reasoning ability. Very little connection was found between the conservation-status of the subjects and their performance…

Seven-year-olds compared successively presented oblique lines which varied as to their position within a square display and their relation to the diagonal axis of the display. Children apparently encoded lines in terms of position and axis features. They used a categorical spatial representational system to compare oblique lines. (Author/RD)

Factor analysis of correlations among the measures of recall clustering, free sorting, and recognition errors revealed significant convergent validity for consistent use of a semantic perceptual organization strategy in the three tasks. Ten-year-old, adult, and elderly adult subjects relied on a semantic strategy; four- and six-year-olds encoded…

The study compared the cognitive, affective, and perceptual role taking skills of 38 learning disabled (LD) children (ages 5 to 8) with those of a control group of normal children. Ss were administered three role taking tasks which measured their skills in each of the domains. The results demonstrated a role taking deficit in the LD children.…
