Visual, auditory, and bimodal event-related potentials were recorded from 50 males, and lateral asymmetry indices were derived. Eleven psychometric tests of different cognitive attributes were also administered to them. This area of research has been labeled aptitude-treatment-interaction (ATI). The emphasis of ATI research is on identification of…

To provide converging support that the integration of analog and propositional representational systems is associated with spatial ability, visual, auditory, and bimodal brain event-related potentials were recorded from 50 right-handed Caucasian male recruits at the Naval Training Center, San Diego. Sensory interaction indices were derived for…

A study used positron emission tomography (PET) to study patterns of brain activation during auditory processing in five high-functioning adults with autism. Results found that participants showed reversed hemispheric dominance during the verbal auditory stimulation and reduced activation of the auditory cortex and cerebellum. (CR)

Recently, knowledge of the mechanisms of visual-spatial attention has improved due to studies employing single cell recording with alert monkeys and studies using performance analysis of neurological patients. These studies suggest that a complex neural network including parts of the posterior parietal lobe and midbrain are involved in covert…

To provide converging support that the proper integration of analog and propositional representational systems is associated with spatial ability, the visual, auditory, and bimodal brain event-related potentials were recorded from 50 right-handed Caucasian males. Sensory interaction indices were derived for these subjects who had taken the Surface…

Paper presented to the Michigan Linguistic Society, Mount Pleasant, Michigan, October 4, 1969. Theorizes that the nature of the brain, not its nurture, inhibits the ability of a person to master the sound patterns of a second language without an accent. (DS)

This article discusses findings concerning the plasticity of auditory cortical processing mechanisms in adults, including the effects of restricted cochlear damage or behavioral training with acoustic stimuli on the frequency selectivity of auditory cortical neurons and evidence for analogous injury- and use-related plasticity in the adult human…

A critical review of neuropsychological results for subjects with bipolar disorder was compared to magnetic resonance imagining (MRI) findings. Studies containing both neuropsychological and MRI outcomes were limited. Therefore, the neuropsychological literature was independently critiqued, then compared to the MRI results from a prior review by…

A defense of the articles published in the September 1981 issue of "School Psychology Review" is provided. Concerns raised regarding the integration and application of neuropsychological knowledge in the school environment are addressed. Readers are urged to reevaluate their concepts regarding the learning problem child. (Author/AL)

This article reviews competing theories of semantic organization in the brain, including modular models, unitary models, and the matrix theory, and provides supporting and refuting evidence for each, incorporating examples from the imaging literature. The literature does provide some support for distinct neural substrates that process specific…

A study of eight adult chronic aphasic patients' comprehension of sentences and pictures in which comparisons of time and space were crucial was designed to assess A. R. Luria's approach to designing comprehension test tasks. The investigation required patients, with lesions of varying size and location, to determine whether a sentence expressing…

Research has suggested that the two hemispheres of the brain serve specialized functions, with the most recent studies portraying the left hemisphere as processing information in a linear, serial, or sequential manner and the right hemisphere as processing information in a holistic, concrete, or visual mode. Although few systematic studies have…

To determine variations in cognitive characteristics, 10 nonretarded men with infantile autism, residual state, were compared with 15 severely dyslexic men and 25 controls on a neuropsychological test battery. The dyslexics showed a reduced digit span and the autistic group exhibited impaired problem-solving skills. (Author/JDD)

Eight males with autism were required to shift attention between rapidly flashed targets alternating between left and right visual hemifields. When targets were separated by less than 700 ms, steady-state brain electrical response in both hemispheres was augmented and background EEG decreased for rightward shifts as compared with leftward shifts.…

Examined the hypothesis that aging and hemispheric laterality interact to produce relatively greater decrements in older individuals in right hemispheric dominant (visuospatial) than left hemispheric dominant (verbal) tasks in 24 early middle-aged and 24 older males. Data did not support the notion of a laterality effect associated with aging.…
