During visually guided grasping movements, visual information is transformed into motor commands. This transformation is known as the "visuomotor map." To investigate limitations in the short-term plasticity of the visuomotor map in normal humans, we studied the maximum grip aperture (MGA) during the reaching phase while subjects grasped objects…

The origin of "special" processing for upright faces has been a matter of ongoing debate. If it is due to generic expertise, as opposed to having some innate component, holistic processing should be learnable for stimuli other than upright faces. Here we assess inverted faces. We trained subjects to discriminate identical twins using up to 1100…

This paper presents a cognitive approach to on-line spatial perception within scenes. A theoretical framework is developed, based on the idea that experience with a scene can activate a complex representation of layout that facilitates subsequent processing of spatial relations within the scene. The representations integrate significant, relevant…

Two experiments tested the DeLoache, Pierroutsakos, Uttal, Rosengren, and Gottlieb (1998) claim that 9-month-old infants attempt to grasp objects depicted in photographs. In Experiment 1, 9-month-olds viewed an object, a photograph of the object, and 2 flat, nonpictorial displays. On average, they reached for the photograph and nonpictorial…

Visual perceptual skills of deaf and normal hearing adults were measured using the Eriksen flanker task. Participants were seated in front of a computer screen while a series of target letters flanked by similar or dissimilar letters was flashed in front of them. Participants were instructed to press one button when they saw an "H," and another…

Background: The object of this study was to analyze the executive functioning of children with attention deficit hyperactivity disorder (ADHD) or reading disability (RD) independent of their non-executive deficits. Methods: Three carefully diagnosed groups of children, aged between 7 and 12 years (35 ADHD, 22 RD and 30 typically developing…

The results of two experimental studies of interference in German-Swedish bilingual and trilingual high school students are presented. Both were developmental studies with length of residence in Sweden as the main independent variable. The purpose was to follow the developmental changes in intra- and interlingual interference and to find out if…

This "kit" consists of 145 activities that teach and reinforce specific pre-reading and beginning reading skills; it has been developed to help the primary grade teacher in recognizing and developing skills that assure each child's continuous reading progress. Part One explains how pre-reading skills are developing reading skills in the…

Perceptual units are involved in the reading process in a particular way. Reading starts with patterns of visual perception visual stimuli in combination with either previously learned information or a strategy for selectively attending to part of the stimuli. Whether the visual pattern selected for deeper information processing is a letter, a…

The purpose and design of a longitudinal study of Project Head Start is summarized in this document, the fourth in a set of ten reports documenting the project. (Material from Project Report 3 was used extensively in preparing this document.) The study was designed to evaluate on a nationwide basis the Head Start Educational Services and to…

Through the use of black and white photographs and drawings interspersed with narrative, this text attempts to foster awareness and appreciation of art in the life of the Lakota Indians. The concepts of space and mass are illustrated. The result of combining masses and spaces into various forms of sculpture (bas relief, monolithic, mobile,…

A perceptual motor approach to learning phonics is presented in this teaching guide which includes a screening test and 50 learning games encompassing a wide array of phonics skills. Directionality, gross-motor skills, sensory-motor skills, and auditory and visual perceptual skills may be introduced to the children and taught during the games…

To investigate the problem of speechreading failure, a battery of tests was administered to 60 deaf children, half of them poor learners and half good. Results indicated that those who developed speechreading did so at an early age and could deal with words, phrases, and sentences spoken at any rate whereas poor learners comprehended only words…

Presented are remedial activities for use by the classroom teacher with learning disabled elementary school children in her regular class. An introductory section discusses specific learning deficits, general motor coordination deficits, and behavior manifestations. Offered are 15 generalizations about teaching the learning disabled child such as…

Describes some of the capabilities of the Apple Macintosh computer in constructing stereo pairs for three-dimensional viewing. Discusses various software packages which can produce the desired graphics. Provides examples of how to use these stereo images in geology, chemistry, and psychology. (TW)
