"Stimulus over-selectivity" describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of…

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…

In this study, metacognition refers to performing visual analysis and discrimination of real life events and situations in naïve psychology, naïve physics, and naïve biology domains. It is used, along with measuring reaction time, to examine differences in the ability of four groups of students to select appropriate pictures that correspond with…

A total of 45 fifth grade students were the subjects of an experiment offering support for a component of learning strategy (memory imagery). Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding and frequency. (MS)

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

Experiments on the development of face recognition showed that young children can ignore featural information when it has no discriminative value and attend to the internal attributes of the face and indicated a lack of developmental differences in face recognition styles, as well as a tendency to rely on configurational information more than…

Investigates the differential effect of modeling procedures on slow and fast responders' performance on a haptic-visual matching test. Also studies the differential effect of modeling of impulsive v reflective modes of responding, and of model success v model failure. (Author/SS)

Presents the procedures, results, and conclusions of a study to investigate the effects of (1) sex, (2) intelligence, and (3) prior experience in puzzle solving on the categorization skills of youth. A two-dimensional type puzzle involving 4 sorting variables was given to 110 ninth graders. 22 subjects, age from 7 to 18 were given a 3-dimensional…

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…

Ten second graders with reading disabilities were presented with the visual analog of an auditory phonological training approach (intrasyllable discrimination) previously studied. Results indicated that children receiving the intervention significantly improved their phonological processing abilities. (SLD)

Reports the results of two experiments dealing with children's visual and tactual performance. In the first task, after several presentations of a series, the tactual group made almost errorless discriminations. But with memory demands, tactual performance became poorer than visual performance. Found a large developmental difference. (JAC)

The construct underlying simple paper-and-pencil logical operations tasks administered to young children in group settings was examined. The logical operations, number concepts, and visual discrimination subtests of the Early School Assessment (ESA) were administered as part of the Fall 1987 national tryout of the ESA. The mathematics concepts and…

Thirty-five second-grade learning disabled children participated in a visual information processing training program designed to teach analysis of visual material into component parts, systematic scanning of visual arrays, pick-up, description, and memory storage of distinctive information, and efficient solution of visual match-to-sample…
