Previous research suggests that model competence does not emerge until relatively late in infancy (20-26 months). Development was systematically analyzed within 3 key areas--count noun learning, dual representation, and categorization--hypothesized to support the emergence of model competence in the second year. In an object-handling preferential…

Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group…

Previous studies have demonstrated the sensitivity of chimpanzees to facial configurations. Three studies further these findings by showing this sensitivity to be specific to second-order relational properties. In humans, this type of configural processing requires prolonged experience and enables subordinate-level discriminations of many…

What happens after visual attention is allocated to an object? Although many theories of attention assume that all of its features are selected and processed, there has been little direct evidence that an irrelevant feature dimension of an attended nontarget is processed. In 5 experiments presented here, the authors used a singleton paradigm to…

We asked whether the ability to keep in working memory the binding between a visual object and its spatial location changes with development across the life span more than memory for item information. Paired arrays of colored squares were identical or differed in the color of one square, and in the latter case, the changed color was unique on…

A study of the differences in the estimates given by older and younger adults of the ages of stimulus persons distributed across the age continuum. (SDH)

This study was designed to determine whether modifying the task characteristics of the Stage 6 sensorimotor means-end problem (by introducing additional visual cues) aided task solution in children. Subjects were 80 children, ages 20-33 months. (CS)

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)

AN OVERVIEW OF THE RESEARCH ON VISUAL DISCRIMINATION SHOWS A TREND FROM THE WHOLE-WORD VIEW TO A COMBINATION OF LETTER-DISCRIMINATION AND THE WHOLE-WORD METHOD. TEN STUDIES CITED IN THIS ARTICLE ATTEMPTED TO ANSWER THE FOLLOWING QUESTIONS--(1) WOULD NONVERBAL STIMULI FACILITATE READING PERFORMANCE, (2) DO CHILDREN FOCUS ON THE SHAPE OF THE WORD OR…

THE SPECIFIC OBJECTIVES OF THE STUDY WERE TO CONFIRM (1) THAT A SHORT PERIOD OF EXPERIMENTAL TEACHING ENHANCES THE VISUAL BEHAVIOR OF PARTIALLY SIGHTED CHILDREN TO THE EXTENT THAT THERE ARE SIGNIFICANT INCREASES IN VISUAL DISCRIMINATION TEST SCORES AND (2) THAT THERE IS A SIGNIFICANT INCREASE IN RECORDED NEAR-VISION ACUITY OF EXPERIMENTAL SUBJECTS…

THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE RELATIVE INFLUENCE OF FIVE VARIABLES (INITIAL INSTRUCTIONS, REWARD, LETTER SIZE, TYPE OF WARM-UP, AND FEEDBACK) ON KINDERGARTEN CHILDREN'S PERFORMANCE OF A LETTER DISCRIMINATION TASK. IT HAS BEEN ARGUED THAT ATTENTION IS THE KEY FACTOR IN LETTER DISCRIMINATION. THE PRESENT STUDY PROPOSES THAT A…

The purpose of this study was to investigate the visual discrimination abilities of regular class children with varying levels of word recognition skill and of special class children. Word recognition and intelligence scores were obtained on 90 primary-aged children in regular classes and on seven children in a special class. The subjects were…

Reports research into the visual fixation of 3- to 11-week old infants as they observed adult faces. Reports a dramatic increase in fixations occurred between 5 and 7 weeks for all conditions. (SL)
