THE LABELING AND DISCRIMINATION OF COLORS WERE STUDIED IN CHILDREN WITH PRIMARY READING RETARDATION AND IN A MATCHED GROUP OF NORMAL CHILDREN. TEN MALE STUDENTS IN MICHIGAN REPRESENTING AN AGE RANGE OF 9 YEARS 10 MONTHS TO 14 YEARS 10 MONTHS WERE CHOSEN AS SUBJECTS. DEVELOPMENTAL, MEDICAL, EDUCATIONAL, NEUROLOGICAL, PSYCHIATRIC, AND PSYCHOMETRIC…

Two experiments involving 42 students from the Model Secondary School for the Deaf investigated both the visual and tactile components in the processing of spatial information. Test measures used were the Figures Rotations Test, Group Embedded Figures Test, and Tactile Rotations Test. The study suggested that spatial reasoning is a determining…

This report is the second in a two-part series introducing an interactive activation model of context effects in perception. In the first part, a model for the perception of letters in words and other contexts was described and applied to a number of experiments. This second part applies the same model to a number of new experiments designed to…

Changes in the perception of figural aftereffects occurring during adulthood were investigated with 56 female subjects. A significant linear trend analysis indicated that the magnitude of the figural aftereffects increased very slightly with age. This was supported by a significant T value which suggested a difference between the two extreme age…

This study is an investigation of 2-month-old infants' abilities to visually localize visual and auditory peripheral stimuli. Each subject (N=40) was presented with 50 trials; 25 of these visual and 25 auditory. The infant was placed in a semi-upright infant seat positioned 122 cm from the center speaker of an arc formed by five loudspeakers. At…

This self-instructional package designed for art students in Grades 5 and 6 enables students to decide which set of lines in a group of lines are parallel, to show the vanishing points of several boxes by extending parallel lines, and to increase their desire to draw objects in perspective. Total time involved for the student is approximately…

This study followed the development of visual preferences in a single infant from birth to 10 weeks of age. The stimuli used were 5 x 10 item arrays of squares of lines in which a 3 x 3 target matrix of the other figure type (line or square) was embedded. The direction of first fixation and the total time spent looking at each side were determined…

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 theoretical orientation based on perceptual development, proposed by Piaget in 1961, is the starting point of this investigation. According to Piaget, the perception of the young child is "centered" on dominant aspects of the field. With maturity, perception becomes "decentered" and progressively freed from the field. The…

Using published research data, the problem of the seriously retarded reader was examined to determine the role of vision. The most obvious visual factors such as acuity and refractive error did not seem related to the problem. Impairment of visual skills such as fusion and accommodation did seem to contribute to reading difficulty, but such…

This annotated bibliography on visual perception and its relation to reading is composed of 55 citations ranging in date from 1952 to 1965. Its divisions include Perception of Shape by Young Children, Perception of Words by Children, Perception in Backward Readers, and Perception of Shapes, Letters, and Words by Adults. Listings which include…

A serial visual afterimage (AI) test was administered to 136 normal and 75 anxiety-ridden children 4-16 years of age. The scoring of the AI serials involved signs of primitive functioning (size-constant and positive AIs), anxiety (large and dark AIs together with primitive AIs in older children) and process discontinuity (intermittent regressions…

This final report attempts to summarize the major findings of three and one-half years of research in the area of understanding and accurately judging others. The author's research on person perception focuses on the use of sound motion pictures of interviews as the primary stimulus and vehicle for the research. Subjects used for these studies…

In a poststimulus cueing task subjects reported either the identity of items or their category membership. Results indicated that readout from Visual Information Storage (VIS) is not selective for conceptual categories. Rapid conceptual categorization of the type found in visual search experiments probably occurs at a processing stage subsequent…

Perceptual motor development, habituation, and learning in squirrel monkeys were studied under controlled rearing and diet history conditions to determine whether the animal's level of behavioral development was similar to well-nourished animals of his own age (agemates) or his own size (sizemates). From birth to 8 weeks of age, the animals were…
