Individuals may be able to exert considerable control over their perceptual experience and environmental awareness by deliberately varying their "cognitive sets" - plans for selecting and processing information. This theme is explored and a research project, which included eleven experiments, on the effects of cognitive sets is reported. (BT)

Empirically describes the relative development of perceptual and conceptual understanding of left-right, back-front, up-down projective relationships between objects and provides a heuristic model of the cognitive processes involved in coordination of perspectives tasks. (Author/ED)

Perceptually handicapped children can be helped through guided discussions of their art work. (DB)

Discrimination learning studied in 3-year-olds, indicated that children over 30 months of age did better than younger children, and girls learned faster than boys after the first problem. (ST)

Second grade children, divided into high and low achievement groups, were tested on a visual vigilance task in which stimuli occurred 24 times in 30 minutes. High achievers responded correctly more often. (ST)

Pictorial depth perception of Tanzanian children was investigated using two versions of Hudson's pictures test. Revised version test scores were higher for all children. (ST)

A study which required children (ages 7-19) to make and justify decisions about which literary fragments belonged to the same work. Responses provided information about relative appeal of style and subject matter; kinds of stimuli and alternatives most likely to elicit literary style sensitivity; and strategies and rationales employed by subjects.…

Human neonates selectively fixated patterns with curved rather than straight contours when the outermost contours differed in this form variable and when quantitative variables were controlled. Data indicated the presence from birth of a discrimination ability basic to later form perception. (Author/ED)

Research conducted by Tadanobu Tsunoda on auditory and visual sensation, designed to test and understand the functions of the cerebral hemispheres, is discussed. Tsunoda discovered that the Japanese responses to sounds by the left and the right sides of the brain are very different from the responses obtained from people from other countries. His…

THE OBJECTIVES OF THIS INITIAL REPORT OF A FOUR-YEAR PROJECT WERE (1) TO DEMONSTRATE A METHOD FOR THE PREDICTION AND PREVENTION OF LEARNING DISABILITIES, (2) TO FOSTER UNDERSTANDING OF CHILD DEVELOPMENT AMONG TEACHERS, PARENTS, AND PHYSICIANS. SUBJECTS WERE THE 3 1/2 TO 5 1/2 YEAR OLD CHILDREN OF AN ENTIRE SCHOOL DISTRICT. RESEARCHERS WERE…

RECENT RESEARCH FINDINGS ON THE PERCEPTUAL DEVELOPMENT OF YOUNG INFANTS WERE SURVEYED, AND THE NEED FOR SYNTHESIZING THESE NEW FINDINGS INTO WORKABLE CONCEPTS WAS SUGGESTED FOR THE FRUITFUL STUDY OF HIGHER ORDER CONSIDERATIONS IN THE FUTURE. A DISCUSSION WAS MADE ON THE DEVELOPMENTAL ISSUES OF--(1) SUPERORDINATE CATEGORIES OF PERCEPTUAL FUNCTION,…

BOTH COGNITIVELY-ORIENTED AND RESPONSE-ORIENTED THEORIES OF PERCEPTUAL LEARNING ARE DISCUSSED AND CONTRASTED WITH A STIMULUS-ORIENTED THEORY. PERCEPTUAL LEARNING IS DEFINED AS AN INCREASE IN SPECIFICITY OF DISCRIMINATION OF THE STIMULUS INPUT. THE AUTHOR DESCRIBED WHAT IS LEARNED IN PERCEPUTAL LEARNING AS () THE DISTINCTIVE FEATURES OF THINGS, (2)…

THE PROGRESS OF AN EXPERIMENTAL RESEARCH PROGRAM IN SPEECH CONTROL WAS REPORTED. DISCUSSION TOPICS WERE (1) PROGRAMED LEARNING OF A SECOND LANGUAGE, (2) A CRITICAL REVIEW OF THE MOTOR THEORY OF SPEECH PERCEPTION, (3) VISUAL CONTROL OF PHONEMIC CONTRASTS (A TEST OF THE MOTOR THEORY OF SPEECH PERCEPTION), (4) SINGLE STIMULUS PROPERTIES IN THE…

This paper reports the major findings and interprets the results of longitudinal and cross-sectional exPeriments concerning the development of visual accommodation in infants 1 to 3 months of age. The stimulus was a high-contrast, random checkerboard which was presented at three different distances from the infants (25, 50 or 100 cm). The physical…

This report is a study of the operation of psychological processes in children in school, and of the application of knowledge about psychological processes to pupil personnel work. Investigated are three kinds of processes: perceptual, intellectual, and affective. The first seven chapters of the report present theoretical models, literature…
