Relevant orientation and mobility (OM) skills for visually impaired infants foster sensory, motor, and conceptual development. OM personnel need to consider alternative teaching models, personnel preparation needs, sensory aids issues, and research issues. (DB)

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classification of mentally retarded children. Results support a distinction between separable and integral stimulus structures, but do not support an integral-to-separable shift in perceptual development. Results suggest implications for…

This paper reviews, first, experimental studies of perceptual-cognitive development and related work directed to the assessment of infant intelligence and, second, naturalistic observation of the exploratory patterns of infants during free play. Techniques used, such as the Fagan Test of Infant Intelligence, offer the potential to identify…

Explored whether there are changes with age in understanding the specific distinction between natural and human-made phenomena and whether an appreciation of this distinction influences children's beliefs about the possibility of altering or transforming different categories of objects. Found that this distinction, a powerful organizer for adults,…

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

Two experiments used Visual Expectations Procedure to investigate development of expectations in infants up to 12 months old. Reaction time improved and the percentage of anticipations increased between 6 and 9 months using an alternation pattern or a complex pivot pattern, and between 4 and 8 months when using a left-right alternation or a…

An overview of cognitve styles and research in the field of field dependence/field independence within the context of the special needs of Hispanic students is presented. Various studies by Witkin et al. on the dimension of field dependence/field independence required the subject to perceive an item independently of the field or context that…

This paper reviews some of the cognitive and linguistic functions which develop during the period of concrete operational thought (ages 4-9) as defined in Piaget's developmental theory. Discussion centers on the formation of classes and relations and the development of the language associated with these operations. Also discussed are conservation…

This paper summarily reviews cross-cultural studies of the art work of lower class black children and middle class white children, research done on cognitive development patterns of inner city blacks, and theories of the way in which experiences with art can affect the cognitive domain of these children. Suggestions for appropriate subject matter…

The experimental program in structured activities in perceptual training was said to have two main objectives: to train children in retention of visual and auditory images and to increase the children's motivation to learn. Eight boys and girls participated in the program for two hours daily for a 10-week period. The age range was 7.0 to 12.10…

The purposes of this study were to determine (1) whether there is a developmental sequence in children's acquisition of metalinguistic abilities and (2) whether the acquisition of these abilities is related to Piagetian operations. Word awareness served as the measure of metalinguistic ability. An attempt was also made to determine whether the…

The differing functions of the left and right hemispheres of the brain are discussed and means of developing interaction between the two are described. (JD)

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

Twenty-six deaf adolescents received instruction in a structured program of cognitive education called "Instrumental Enrichment." The program addresses, among other processes, comparison, classification, logical progression, spatial orientation, analysis and synthesis, and syllogistic thinking. Following training, the subjects showed…
