The few studies concentrating on adult age changes in discrimination shift behavior have reported that the performance of elderly adults on such tasks is inferior to that of younger adults and, in fact, similar to that of children. To determine whether verbal labeling, which has facilitated the performance of young children, would also reduce age…

To describe and compare the psychosensory functioning of normal children and children with specific learning disabilities, 62 learning disabled and 68 normal children were studied. Each child was given a battery of thirteen subtests on an automated psychosensory system representing various combinations of auditory and visual intra- and…

Thirty-two Afro-American and 50 Mexican-American seventh graders were randomly selected from a school located in a central Texas low socioeconomic environment. The subjects were administered the New Developmental Reading Tests, The Silent Reading Diagnostic Tests, and The California Short-Form Test of Mental Maturity. When the two groups were…

Forty students, grades 4 and 8, were given match-to-sample tests on Western art, to gauge their ability to recognize paintings by the same artist. Eighth-graders performed reliably better than fourth-graders, and their matching justifications were more advanced. Prior artistic experiences improved style sensitivity. (SJL)

CHANGE IN INFORMATION PROCESSING AND CHANNEL CAPACITY WITH INCREASE IN AGE WAS STUDIED, AND POSSIBLE ALTERING OF THIS RELATIONSHIP WITH A CHANGE IN COMPLEXITY AND DIMENSIONALITY OF THE STIMULUS PRESENTED. VISUAL STIMULI WERE PROJECTED ON A SCREEN TO FOUR GROUPS COMPOSED OF 74 COLLEGE GRADUATES, RANGING IN AGE FROM 23 TO 68 YEARS, IN A SIMULATED…

This paper presents two studies of the development of social competencies in infancy. In the first experiment, the central issue investigated was whether facial configuration or height is utilized by infants to respond differentially to children and adults. Five different strangers, a male and a female child, a male and a female adult, and a small…

This appendix includes seven papers which focus on various aspects of the learning processes of children ages 5-7: (1) S. Thompson, "Transitions to concrete operations: A survey of Piaget's writings" (in outline form); (2) S. H. White, "Changes in learning processes in the late preschool years," an examination of cross-cultural…

In the first experiment, the development of the ability to copy alphabet letters by black males aged 3-9 (middle and low S.E.S.) was studied, using a newly-developed scoring system. In the second experiment, kindergarteners learned to associate letter names with six lower-case printed letters by the anticipation method. The addition of an…

This is the second of a two volume report of a Day Care Inventory. The author presents an evaluation of the Inventory and make recommendations for changes, deletions and additions so that more satisfactory measures will be available for use in the study of the impact of day care on child development. The evaluations are based upon the findings…

Simple and complex learning and problem solving situations were employed with mentally retarded children and adults. In the Rotation-Discrimination Complex and the Size-Discrimination Simple experiments, upper and lower test achievement subgroups were subjected to two basic types of visual discrimination at different levels of task complexity.…

The Seguin Form Board Test is used to assess visual discrimination and matching and eye-hand coordination. Previous analysis has shown the vactor loadings for the same scale to differ among age levels, so the test may be measuring different abilities at different age levels. Test materials consist of ten differently shaped wooden blocks and a…
