Verbal-to-spatial associations in working memory may index a core capacity for abstract information limited in the amount concurrently retained. However, what look like associative, abstract representations could instead reflect verbal and spatial codes held separately and then used in parallel. We investigated this issue in two experiments on…

A preliminary investigation of patterns of teacher thought about student reasoning and learning involved presenting 23 preservice teachers with a "dilemma of practice about equity." Resulting stages of teacher development concerning equity in reasoning were found to correlate significantly with Perry's scheme. However for those who hold…

This booklet describes only a glimpse of what is known about the nervous system, brain disorders, and the exciting avenues of research that promise new therapies for many of the most devastating neurological and psychiatric diseases. The neuron, brain development, sensation and perception, learning and memory, movement, advances and challenges in…

A simulation experiment demonstrated that the perceptual sensitivity of Swedish and Danish students at upper secondary school level varies systematically concerning the basic conditions for "personal growth." An attempt is made to constrain this concept contextually, in such a way that it can be described behaviorally. It is made evident…

Goals and challenges pertaining to infant sensory and perceptual development are discussed. It is suggested that the inability of researchers to think and talk wisely about "partial accomplishments" in development creates a barrier in developmental research. Conceptual schemes are needed to accommodate these partial accomplishments. Three major…

Even at an early age, children are guided by their intuitions as they write. Intuitions are the culmination of perceptions that have been internalized and synthesized into patterns. Furthermore, they take time to develop. Consequently, if systematic instruction is to play a part in the formation of intuitions about written language then it must…

A mathematics curriculum for moderately and severely retarded and autistic students and adults should possess 10 necessary characteristics, including provision for instruction based on assessment results, stress on functional application, focus on generalization of skills, and specific criteria for mastery of each skill. The functional but…

Based on a prior model on modularity of the brain, a new modular model of intrapersonal communication was developed which focuses on brain processing, encompassing both the structures and the functions of those structures in the creation of messages. The modular mind is a bio-social model of communication which presupposes a relationship between…

These proceedings contain 37 papers from 51 authors noted for their expertise in the field of visual literacy. The collection is divided into three sections: (1) "Examining Visual Literacy" (including, in addition to a 7-year International Visual Literacy Association bibliography covering the period from 1983-1989, papers on the perception of…

The purpose of this study was to determine if intervention instruction in encoding processes affects novice teacher problem solving ability in educational contexts of varying levels of complexity. It sought to determine the effects of intervention training in nine specific encoding processes, prerequisite to effective problem solving, on novice…

An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning. Subjects, who ranged in…

To demonstrate that a pediatric clinic provides a natural framework for an educational program involving parents as the primary teachers of young children, a parent education program was incorporated into the playroom program of the Mount Sinai Hospital Pediatric Clinic in New York City.

Using a sample of 77 10th grade boys, the researchers studied the relationships between the mental abilities measured by the Differential Aptitude Tests and cerebral dominance (CD: the extent to which one hemisphere of the brain dominates the other for control of behavior). The surprise finding was that CD was negatively related to spatial…
