To act and think, children and adults are continually required to ignore irrelevant visual information to focus on task-relevant items. As real-world visual information is organized into structures, we designed a feature visual search task containing 3-level hierarchical stimuli (i.e., local shapes that constituted intermediate shapes that formed…

This study tested whether the first level in processing orientation information results in perceiving whether a shape is upright or nonupright. Theory states that nonupright orientations are not distinguished from each other. As predicted, three- and four-year-olds discriminated upright from nonupright pictures more readily than they discriminated…

In four year olds who had been exposed to polychlorinated biphenyls (PCBs) before birth, prenatal exposure was associated with less efficient visual discrimination processing and more errors in short memory scanning. Postnatal exposure was unrelated to cognitive performance. (GLR)

Subjects from kindergarten-age to adult participated in four experiments. In order to view the stimuli, subjects in three experiments activated lights in viewing boxes; in the fourth experiment, stimulus fixations were measured using a corneal reflection technique. Results supported the view that visual observing is controlled by cognitive…

This experimental study was conducted in an attempt to determine how children--four, seven, and 11 years old--perceive implied motion cues in combination with a variety of objects. Ninety children, 30 in each age group, were shown 24 pictures. There were three kinds of objects, each with an inherent active and static dimension. Each of these six…

The reflection-impulsivity (R-I) dimension of individual variation incognitive processes is discussed. A literature review focuses on studies that have supported the validity of the R-I dimension as a concept, and studies providing evidence of a direct relationship between the R-I dimension and visual scanningstrategies. This study compares the…

This study utilized a recognition procedure to directly assess preschool children's ability to discriminate between programs and commercials in an actual viewing situation. Seventy-two children, equally grouped by sex and age (3, 4, and 5 years) were individually presented with three videotapes. Each tape contained a sample of a 48 ten-second…

INFANT SCRIBBLING ACTIVITY IS NOT SIMPLY PLAY. IT CONTRIBUTES TO THE DEVELOPMENT OF VISUAL ATTENTION AND PERCEPTION. YET, SCRIBBLING, UNLIKE WRITING IN THE COMMUNICATION SENSE, IS NOT MOTIVATED BY THE DESIRE TO INFORM, NOR TO SET DOWN THOUGHTS AND FEELINGS. THE EXPERIMENTAL HYPOTHESIS OF THIS STUDY WAS THAT THE MOTIVATIONS FOR SCRIBBLING ARE (1)…

THE LITERATURE ON LANGUAGE ABILITY AND ITS RELATIONSHIP TO ACADEMIC SUCCESS INCREASINGLY VOICES ALARM THAT THE CULTURALLY DISADVANTAGED ARE SERIOUSLY DEFICIENT IN LANGUAGE ABILITY. INTERVENTION PROGRAMS CREATED TO CORRECT THIS PROBLEM ALL RECOGNIZE THE IMPORTANCE OF LANGUAGE TOOLS FOR INTELLECTUAL FUNCTIONING. ESSENTIAL TO SUCH PROGRAMS, AND…
