Previous experiments with nursery school children have suggested that (1) subjects of preschool age do not verbalize during transfer learning or that (2) for these subjects, self-produced verbal cues have little influence on the learning process. To investigate the relative merits of these alternative positions, research was conducted among 80…

Extensive research has proven that the functions of the two hemispheres of the brain tend to be qualitatively different. The left hemisphere, which for most people is dominant, is the major controller of speech, reading, and writing; it is the hemisphere toward which education traditionally has been directed. The right hemisphere excels in…

The research experiments on relational learning in young children contained in this report were guided by two major goals: (1) to examine the extent of conceptual transfer in preschool children, and (2) to explore the relation of both "acquisition" and "transfer" to chronological development. The performance of preschool…

Elementary school (kindergarten through sixth grade) deaf children were exposed to varied thinking activities based on J. Piaget's principle of action rooted intelligence to determine if thinking might be successfully encouraged in the classroom through activities which were not highly dependent on verbal performance. Each class of approximately…

Differences in performance IQs between deaf children of hearing parents (HP), deaf children of deaf parents (DP), and hearing children (HC) may be a result of differences in speed of information processing. DP adolescents were found to have faster reaction and movement times than HP or HC subjects along with equivalent IQs. (Author/VW)

This book presents research on how some innovations in computer visualization are making work and education more favorable to visual thinking. The book exposes many popular myths about conventional intelligence through an examination of the role of visual-spatial strengths and verbal weaknesses in the lives of 11 gifted individuals, including…

This discussion of speech and language development in individuals with nonverbal learning disabilities (NLD) reviews NLD assets, deficits, and dynamics; the white matter model; manifestations of NLD in neurological dysfunction; psycholinguistic dimensions of NLD in terms of language content, form, and use; developmental considerations in NLD; and…

TgCRND8 mice represent a transgenic mouse model of Alzheimer's disease, with onset of cognitive impairment and increasing amyloid-[beta] plaques in their brains at 12 weeks of age. In this study, the spatial memory in 25- to 30-week-old TgCRND8 mice was analyzed in two reference and one working memory Morris water maze (MWM) tests. In reference…

A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for…

The impact of a previously successful or unsuccessful experience on the subsequent acquisition of a related task is not well understood. The nature of past experience may have even greater impact in individuals with learning deficits, as their cognitive processes can be easily disrupted. Mice with a targeted disruption of the [alpha] and [delta]…

Summarizes experiments indicating that a basic key to learning is the development of concepts of pattern recognition and the appropriateness of using a particular theorem. (Author/SK)

Two experiments examined the effects of reductions in cortical cholinergic function on performance of a novel task that allowed for the simultaneous assessment of attention to a visual stimulus and memory for that stimulus over a variable delay within the same test session. In the first experiment, infusions of the muscarinic receptor antagonist…

A recent study suggests that lesions to all major areas of the cholinergic basal forebrain in the rat (medial septum, horizontal limb of the diagonal band of Broca, and nucleus basalis magnocellularis) impair a spatial working memory task. However, this experiment used a surgical technique that may have damaged cerebellar Purkinje cells. The…

This study investigated the premise that disordered temporal order perception in retarded readers can be seen in the serial processing of both nonverbal auditory and visual information, and examined whether such information processing deficits relate to level of reading ability. The adult subjects included 20 in the dyslexic group, 12 in the…

Notes that almost all computer engineering textbooks present algorithms using only verbal methods. Poses that engineering students' ability to handle graphic representation is crucial yet information is presented verbally. Summarizes the results of 12 replications on learner preference for graphic or verbal algorithmic techniques. (MVL)
