There is overwhelming evidence that children's first words are primarily nouns even across languages. These data are interpreted as evidence of a "Natural Partitions Theory," one that holds that the concepts referred to by nouns are conceptually more basic than those referred to by verbs or prepositions. Analysis of data from…

Children, 24-36 months old, were studied in an effort to examine the influence of cognitive development on the nature of information extracted from stimuli and coded into memory. (ST)

The ability of 3-, 4-, and 5-year-old children to infer the position of an object in a room from information contained on a map was assessed under five conditions: (1) map aligned inside the room (the pretest); (2) map aligned outside the room; (3) map rotated 180 degrees inside the room; (4) map rotated 180 degrees outside the room; (5) map held…

This study suggests and identifies computer image generation (CIG) algorithms for visual simulation that improve the training effectiveness of CIG simulators and identifies areas of basic research in visual perception that are significant for improving CIG technology. The first phase of the project entailed observing three existing CIG simulators.…

THIS RESEARCH ATTEMPTED TO ESTABLISH A BETTER UNDERSTANDING OF THE PROBLEMS OF CONGENITALLY TOTALLY BLIND CHILDREN AND TO TEST THE POSSIBILITY OF MEETING THESE PROBLEMS WITH A SPECIAL TRAINING PROGRAM IN GENERAL ORIENTATION AND SPACE PERCEPTION. A SAMPLE OF 60 CHILDREN WAS SELECTED FOR THE EXPERIMENT. THESE SUBJECTS WERE WITHOUT ADDITIONAL…

CHARACTERISTICS OF THE INTELLECTUAL PROCESSES OF THE LOW-INCOME CHILD ARE PRESENTED. THE MAJOR IMPOVERISHMENT OF THESE CHILDREN IS IN THE AREA OF LANGUAGE SKILLS. ANOTHER CHARACTERISTIC IS THEIR POOR PERFORMANCE ON INTELLIGENCE TESTS. IN THE AREA OF PERCEPTIONAL PROCESSES THESE CHILDREN CAN NEITHER DISCRIMINATE SOUNDS WELL NOR PERFORM WELL ON…

This study of cognitive and perceptual development compared low SES minority urban children participating in special programs with middle SES minority urban children and with the national norms on cognitive and perceptual measures. Subjects were 169 4- and 5-year-old minority urban children attending preschools in a large city. Eighteen middle…

As a child matures from infancy to early childhood, a shift occurs in his sensory hierarchy from tactile to auditory to visual. The transition between the predominance of the auditory sense and visual sense takes place in about grades four and five. Although the sensory systems do not function singularly (but are integrated in the total action…

The purpose of this research was to explore the level of perceptual processing being used by normal and educable mentally retarded beginning readers. The investigation tested the hypothesis that beginning readers show a positive relationship between word length and word recognition latency, implying serial processing. Data on accuracy and latency…

This research project was designed to determine whether 1-week-old neonates would indicate biological recognition of their mothers. Biological recognition is defined as the particular configuration of sensory, kinesthetic, and motor cues and the temporal patterning of these cues which characterizes infants' exchange processes with their…
