Discusses the irregularity and unpredictability of the human body. Presented are pictures showing the fractallike structures and research findings on the mechanism for chaos in the human body. Lists four further reading materials. (YP)

An irrelevant auditory probe procedure was employed to evoke brain event-related potentials (ERPs) in 56 right-handed Caucasian males while they learned concepts presented to them in study booklets. A mastery test was administered to assess concept acquisition. Subjects were divided into two groups according to whether or not their achievement…

Reviews a study which sought to obtain a quantitative metabolic map of the neurons mediating a specific memory. Research results support notions of cooperative processes in which nonrandom behavior of high ensembles of neural elements mediates the integration and processing of information and the retrieval of memory. (ML)

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…

Reports relationship between asymmetries in frontal-brain electrical activity and individual differences in affective response in 35 ten-month-old females. Stranger-approach, mother-approach, and maternal-separation experiences were presented while an electroencephalogram (EEG) from scalp regions was recorded and facial and other behavioral…

The developmental pattern of concurrent synaptogenesis in rhesus monkeys is consistent with a straightforward model of relations between brain and cognitive development. Concurrent synaptogenesis is hypothesized to lay the primary cortical foundation for a series of developmental levels in middle infancy that have been empirically documented in…

Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)

A theory of normal and delayed development of language is presented, arguing that linguistic capacity develops in gradual, sequential, critically timed phases; children with slowly developing brains have delays in storing utterances; a critical period for activation of experience-dependent grammatical mechanisms declines without optimal result;…

Despite a long history and considerable study, leadership remains a notoriously perplexing and enigmatic phenomenon. Although the "new leadership" perspective has revived convictions and general interest in leadership studies, conceptual and methodological problems nevertheless remain a feature of the research and theory-building terrain, and some…

This study measured unilateral, tachistoscopic naming reaction times of 30 normal and 30 reading-disordered children (mean age of 9.3 years) to objects representing two levels of picture vocabulary age. Reading disabled subjects are enrolled in the Reading Center, a diagnostic and treatment program for disabled readers at Bowling Green State…

High-level visual processes make use of stored information, and are invoked during object identification, navigation, tracking, and visual mental imagery. The work presented in this document has resulted in a theory of the component "processing subsystems" used in high-level vision. This theory was developed by considering…

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…

Explains the hierarchic structure of the mammalian visual system. Proposes a model in which feedback pathways serve to modify sensory stimuli in ways that enhance and complete sensory input patterns. Investigates the functioning of the system through computer simulations. (ML)

A questionnaire was developed and administered to 30 young children with autism and a control group to explore sensory hyper- and hypo-sensitivities. Significant differences were found between groups across all (auditory, tactile, visual, gustatory, and vestibular) domains. Findings are interpreted within the framework of theory of mind and joint…

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…
