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)

Forty preschoolers were directed to mentally rotate a stimulus and to discriminate the rotated stimulus from among a set of alternatives. Results are discussed in light of discrepant findings about children's kinetic imagery ability and the advisability of using this particular paradigm with young children. (Author/BS)

Introspective experiences that nine University of Tulsa (Oklahoma) faculty members (aged 29-52 years) have when acquiring cognitive skills without awareness were studied as they acquired nonconscious knowledge about a pattern of stimuli. Nonconsciously acquired knowledge was automatically used to facilitate performance, without conscious…

Examines research related to the retina's coding of visual input with emphasis on the organization of two kinds of ganglion cell receptive fields. Reviews current techniques for examining the shapes and arrangement in the retina of entire populations of nerve cells. (ML)

The ability of 40 children four and five years of age to discriminate reflections and rotations of visual stimuli was examined in a kinetic imagery task. Results revealed that prediction accuracy was associated with the existence of orientation markers on the stimuli, as well as age, sex, type of discrimination, and several interactions among the…

Two autistic children (5 and 13 years old) acquired functional sight-word reading skills in a play activity. Ss gained access to preferred toys by selecting toy labels in tasks requiring increasingly complex visual discriminations. Ss showed comprehension on probes requiring reading skills to locate toys stored in labeled boxes. (Author/CL)

Replies to argument presenting evidence against a model of habituation during early infancy which was based on the selective adaptation of feature detectors. (Author/BB)

Two experiments investigated characteristic generalized imitation procedures on a nonimitative successive visual discrimination task. (Editor)
