Meaningful visual experience requires computations that identify objects as the same persisting individuals over time, motion, occlusion, and featural change. This article explores these computations in the tunnel effect: When an object moves behind an occluder, and then an object later emerges following a consistent trajectory, observers…

Two experiments were conducted to determine the relative importance of style of movement versus physical appearance in person recognition. The first study investigated the capabilities of young children and adults to recognize target individuals' styles or manners of movement and to distinguish between people when their faces were not visible. A…

This study investigated the hypothesis that there is a developmental trend toward greater flexibility of strategies in visual selection. Subjects were 48 second and sixth graders. (Author/SDH)

The ability of 1-month-old infants to recognize their mothers visually was explored with the live faces of mother and stranger presented in three different poses: en face (full face), half-profile, and profile. Subjects were 16 infants with normal Apgar scores at birth who were volunteered by their parents after an initial contact in a maternity…

This report summarizes the results of more than 10,000 individual judgments, carried out in five related studies, all concerned with perceived reading efforts of text on visual displays and printouts. Students and personnel in the Department of Computer Science at the University of Stockholm served as study subjects. In experiments in which…

Young children matching the orientation of (a) identical realistic figures that could form mirror images of each other, or (b) nonidentical realistic figures that could not form mirror images, produced the same pattern of errors. The explanation proposed is a strategy of matching analogous parts of the two figures. (Author/SDH)

Elementary school children made same-different judgments of prototypes of letterlike forms paired with transforms of these prototypes generated on a dimension either critical or noncritical for object identification. Results challenge the view that dimensions irrelevant in object identification are ignored or not detected in graphic…

This study explores the reason why very young infants are unable to respond differentially to faces and the cause for developmental changes in infant face perception by age 3 months. Linear systems analysis (LSA) and the contrast sensitivity function (CSF) were used to estimate the facial pattern information available to 1- and 3-month-old…

THE HYPOTHESIS THAT ENVIRONMENTAL CIRCUMSTANCES INFLUENCE THE PROCESS OF KNOWLEDGE ACQUISITION IS DISCUSSED. THE ROLE OF PARTIAL AND FULL SENSORY ISOLATION AND DEPRIVATION AND ITS NEGATIVE EFFECT ON LEARNING IS SHOWN TO BE SUPPORTED BY RESEARCH. THE INSTITUTE FOR DEVELOPMENTAL STUDIES AT NEW YORK UNIVERSITY IS ENGAGED IN RESEARCH DEALING WITH THE…

THE USE OF THE OPAQUE PROJECTOR SEEMS TO BE AN EFFECTIVE AID FOR DEVELOPING GOOD VISUAL DISCRIMINATION, LANGUAGE AWARENESS AND READING SKILLS IN IMAGERY FORMATION, SPEED, PHRASING, INTONATION AND EYE MOVEMENT. IT SHOULD BE PART OF A WELL-ROUNDED PROGRAM INCLUDING THE RECOGNIZED TECHNIQUES FOR TEACHING CULTURALLY DISADVANTAGED CHILDREN. READING…

THIS STUDY INVESTIGATED THE EXTENT TO WHICH SOUND FILM RECORDINGS OF PUPILS IN TEACHING-LEARNING SITUATIONS CAN BE USED AS A BASIS FOR TRAINING TEACHERS TO IMPROVE THEIR ACCURACY IN INTERPRETING NONVERBAL COMMUNICATIONS, AND THE EXTENT OF DIFFERENCES AMONG TEACHERS, NEW TEACHERS, AND NONTEACHERS IN THEIR ABILITY TO INTERPRET NONVERBAL…

Two 4-year-old children were shown the use of an apparatus whereby they could obtain toys and candy by making certain responses. The apparatus was a matching-to-sample device on which were arranged five response buttons in a circle and one in the middle. Each response button had a display window for the stimulus. Four of the five windows on the…
