Fifty-eight undergraduates took part in an experiment evaluating a full-spectrum light closely approximating natural sunlight and a cool-white fluorescent light commonly used in institutional settings. Four classes of a single teaching assistant were used and each class was compared against itself under different lighting conditions. Data were…

The present study attempted to uncover some of the psychological processes which mediate the relationship between visual behavior and feelings of intimacy, and to clarify the conceptual and methodological issues raised by such an endeavor. (Author/RK)

Reports two experiments which examined developmental changes in the patterns of preference for varying degrees of perspective while controlling for the station point used in viewing. Subjects were 28 preschool children (age four years), 23 elementary school students (age six years) and 30 college students from introductory psychology classes. (MP)

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

Notes that the fluent reader needs rapid perception, the ability to use semantic and syntactic clues, and sophisticated comprehension strategies. (MKM)

In order to investigate the role of visual perceptual abilities in the acquisition and comprehension of sign language, four tests of perceptual ability were administered to 120 entering hearing-impaired students and 23 new hearing staff members at the National Technical Institute for the Deaf.

Explores (1) problems of the validity of tests of spatial ability, and (2) problems of the recessive gene influence theory of the origin of sex differences in spatial ability. Studies of cognitive strategies in spatial problem solving are suggested as a way to further investigate recessive gene influence. (Author/RH)

Although painting is still recognized as an international language, few people are actually capable of "reading" the great works of art that have given depth to mankind's existence. Here is a lesson in "reading a painting". (Author/RK)

Investigates the experimental treatments (scanning practice and perceptual training-drawing) developed by Salome and Szeto, 1976, in an attempt to determine the training effects upon students' representational drawing performances. (Author/RK)

Outlines briefly the historical development of the field of learning disabilities, describes its present status with a discussion of some of the major issues and controversies, and indicates some emerging trends and future directions. (Author/RK)

Eight, ten, and twelve year old children were tested on a novel procedure involving the successive presentation of standard and comparision stimuli. Two hypotheses were evaluated: one dealing with memory effects, and the other with children's pretesting of choice responses in spatial information processing. (Editor/RK)

35 undergraduates segmented one of two videotapes of an actor methodically assembling 20 five-page questionnaires. Tests the hypothesis that behavior that differs systematically in the availability of action-defining changes will be segmented into perceived actions in a systematically different way. (Author/RK)

The effects of visual paradigmatic organization on verbal recall among language/learning disabled children was studied with 20 such children (age: 8-13 years), who were screened to eliminate visual memory deficits. (Author)

Three word-identification experiments suggest that a model derived from experiments with pseudowords can be applied successfully to word identification. The data derived from the experiments confirm the role of higher order verbal units in word identification and suggest the structural components of a verbal-mediation theory of reading. (Editor/RK)

The aim of this study was to examine pattern difficulty as a general factor influencing orientation errors, and to explore psychological differentiation and task perception as variables accounting for cross-cultural differences. Samples of 30 boys and 30 girls in Ghana and Scotland were tested. (Editor)
