Visual categorization is ubiquitous in many professions, yet training programs are typically time- and effort-intensive. This work focuses on developing methods to improve human learning and performance on challenging visual categorization tasks, e.g., bird species identification, diagnostic dermatology. As part of the general approach, we infer…

This study investigated whether object-picture discrepancy occurs because preschool children regard pictures as significates rather than as signifiers. Results indicated the children did not consistently respond to objects and their pictorial representations equivalently. (Author/DB)

Object substitution masking (OSM) is said to occur when a perceptual object is hypothesized that is mismatched by subsequent sensory evidence, leading to a new hypothesized object being substituted for the first. For example, when a brief target is accompanied by a longer lasting display of nonoverlapping mask elements, reporting of target…

Presents the procedures, results, and conclusions of a study designed to examine the performance of three distinct socioeconomic groups on several dimensions of resemblance sorting. (LC)

Noting that children who can easily categorize a picture in terms of what it depicts may have difficulty understanding the picture as a representation or thing in itself, four experiments with children around four years old examined their responses to pictures as things in themselves. Results showed that some children had difficulty understanding…

THE EFFECTS OF INSTRUCTIONS, TYPE OF LABEL, TYPE OF CONCEPT, AND SEQUENCE OF CONCEPTS BY TYPE UPON CONCEPT IDENTIFICATION WERE INVESTIGATED IN THIS STUDY. PERFORMANCE WAS ANALYZED IN TERMS OF FOUR TYPES OF TEST ITEMS. INSTRUCTION, FOCUSING ON THE CONCEPT TO BE ATTAINED AND THE CONCEPT NATURE, WAS FOUND TO FACILITATE CONCEPT IDENTIFICATION…

Early acquisition of right and left as absolute concepts does not seem to be related to early mastery of right and left as relative concepts among the Hausa. (Author)

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

Infants 8.5 and 9.5 months of age were tested for ability to determine the location of an object hidden in one of two covered containers before their left-right positions were reversed. Only the older infants provided with different colored covers to their containers were able to do this task. (Author/DB)

Experimental conditions consisting of visual experience, visual plus motor training, visual plus verbal-orienting instruction, visual plus motor plus verbal, and a control group were used to study young children's concept development. Assessment was based on discriminating and remembering positive concept instances and classifying concept…

THE RELATIONSHIPS BETWEEN AUDITORY AND VISUAL FUNCTIONING AND READING ACHIEVEMENT WERE EXPLORED. AN ADDITIONAL OBJECTIVE WAS TO INVESTIGATE THE INFLUENCE OF DEVELOPMENTAL FACTORS ON THESE VARIABLES. A WIDE RANGE OF AUDITORY AND VISUAL SKILLS WAS SAMPLED IN POOR AND NORMAL READERS AT THREE DIFFERENT GRADE LEVELS (FIRST, THIRD, AND FIFTH). DATA…

A detailed program for the development of pre-reading visual perceptual skills in young children is presented which provides benefits to both teacher and child due to its scope and flexibility. The program is primarily visual-motor, providing at the same time experiences in language and concept development. The prescribed sequence of lessons…
