The study investigated cerebral organization for visual language processing with 14 adult stutterers. Results showed the right hemisphere was superior for analyzing the concrete words while the left hemisphere was responsible for processing the abstract items suggesting some form of linguistic competition between the two hemispheres of this…

Alaska's "The Early Years, The Critical Years" conference was designed to educate participants about current brain research, give them an opportunity to discuss public policy with state administrators, provide a forum to develop recommendations and activities to support young children in Alaska, and offer quality training about early…

Minimal brain dysfunction has been redefined by the American Psychological Association as attention deficit disorder (ADD) and subdivided into categories with and without hyperactivity. The revised 'Diagnostic and Statistical Manual' (DSM III) is now undergoing field trials. Journal Availability: C. V. Mosby Company, 11830 Westline Industrial…

Describes the role of mushroom bodies--cup-shaped structures perched atop the brain of an insect--in learning. Mushroom bodies may help fruit flies in learning meaningful odors, cockroaches in spatial learning, and honeybees both in locating pollen and nectar and in navigating back to the colony. (PVD)

Correlated brain size differences with 37 musculoskeletal variables shown in evolutionary textbooks to change with brain size. Findings from a sample of more than 6,000 U.S. military personnel indicate that racial differences in brain size are securely established and are the most likely biological mediators of race differences in intelligence.…

Studied the influence of task content and sex on the relationship between intelligence and cortical activation in 26 males and 25 females administered verbal, numerical, and figural versions of an elementary cognitive task. Results suggest comparatively lower cortical activation in more intelligent individuals, but the pattern interacted with sex…

Communication is both cognitive and intuitive, although schooling stresses left-brain skills. Ways to develop intuitive (right-brain) skills include mandalas, Jung's technique for concentrating the right brain; writing with the nondominant hand; and positive affirmations. (SK)

Reviews research on the brain and memory, emotions, aging, and learning. Outlines practice implications: connect new learning to personal experiences, make sure learners are paying attention, recognize the role of emotions, and be aware that stimulation influences the aging brain. (SK)

Responds to previous studies on the relationship between event-related brain potential (ERP) responses to linguistic syntactic anomalies and domain-general unexpected events. After reviewing relevant data, this paper concludes that the ERP response to syntactic anomalies is at least partially distinct from the ERP response to unexpected anomalies…

Summarizes a theoretical framework and set of hypotheses aimed at accounting for consciousness in neurobiological terms. Discusses the functional neuroanatomy of nuclei in the brainstem reticular formation. Notes that the views presented are compatible with the idea that the reticular formation modulates the electrophysiological activity of the…

Describes the evolution of humans. Focuses on the brain and discusses cognition and symbolism, and language and the emergence of human cognition. (YDS)

Examined covert attention shifts in infants with event-related potentials (ERPs). Found that reaction time to localize target showed covert attention shifts. There was a larger P1 ERP component on valid trials than on invalid trials or on no-cue control trials. Pre-saccadic ERP potentials in response to target were larger when target was in cued…
