THE IMPACT OF TWO TREATMENTS OF LEARNING EXPERIENCES ON THE ABILITIES OF PRESCHOOL CHILDREN WERE STUDIED. THE LEARNING EXPERIENCES INVOLVED PRINCIPLES OF HAPTIC (TACTUAL) PERCEPTION IN THE PERFORMANCE OF VARIOUS TASKS. CHILDREN, AGES 3 THROUGH 5, FROM HIGH AND LOW ECONOMIC LEVELS WERE SELECTED AS SUBJECTS. AN ANALYSIS WAS MADE OF THEIR HAPTIC…

Reported are the results of a series of studies conducted to identify the possible correlates of perceptual curiosity in retarded and normal IQ Ss (13-21 years old), and to determine the modifiability of perceptual curiosity in mentally retarded Ss through training and the possible transfer effects of such training. In a section on general…

This paper describes two experiments in which children in grades 1, 3, and 5 were given three kinds of spatial perspective-taking problems to solve as quickly as they could: (1) C problems, solvable only by computation (that is, noting which features of a particular object array were closest to another observer in order to estimate how the array…

A sample of 310 Canadian kindergartners were interviewed on (1) recognition of reading/writing acts, (2) concepts of reading/writing purposes, (3) concepts of printed material's features, and (4) visual perception. Part 4 scores were nearly perfect. Ascendingly, parts 1, 2, and 3 were found increasingly difficult. Concludes teachers should…

Ten young males (aged 16-to-22 years) whose IQ scores ranged from 51 to 77 were compared on a simple discrimination task with ten male university students (aged 18-to-23 years) and 28 nonretarded male children (aged 7-to-11 years) in order to determine if reaction time is a consequence of mental retardation.

Two experiments involving listening preferences of autistic and normal Ss were conducted to test the hypothesis that the right cerebral hemisphere is more active than the left in autistic children. (Author/BD)

This replication study negates Bruner's finding that older subjects (age 15 and adult) understand the mathematical concept of ratio as exemplified by comparing judgments of fullness in pairs of glasses differing in height, diameter, and water volume. Weaknesses in Bruner's design and procedure that explain the discrepancy between the two studies…

Discusses hypotheses suggested for consideration by those black educators and parents who are involved in the educational process with the black child; these hypotheses are based on extensive clinical investigation and research. It is contended that black independent schools are facing the same complex problem that has plagued Western…

Ability to take the visual perspective of another was studied among 97 Anglo American and Mexican American boys and girls aged 5 to 6 and 7 to 9. (BD)

Describes the school-related activities and the components of a week-long science camp program which aims to develop reading and science skills and to heighten each student's sensorial awareness. (GO)

A study involving 8 children (mean age 9.3 years; seven Ss with possible visual-perceptual disability) was conducted to determine if directed art activities could increase visual perception as measured by the Frostig Developmental Test of Visual Perception. (SBH)

Development of object permanence skills was examined longitudinally in 20 visually impaired infants (ages 4-25 months). Order of skill acquisition and span of time required to master skills paralleled that of sighted infants, but the visually impaired subjects were 8-12 months older than sighted counterparts when similar skills were acquired.…

Investigates the relationship between hemisphere, brain preferences, and academic failure or success by studying 131 average and above average fourth and seventh grade students. Concludes that cerebral hemisphere functions do affect learning. (MM)

Examines whether three-month-old infants can detect variations within the single expression category of smiling and whether individual differences in infants' sensitivities are related to identifiable mother or infant behaviors. (HOD)
