This study examined whether children (ages 6-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H) could be differentiated from those diagnosed as having attention deficit disorder without hyperactivity (ADD/WO), on an anterior-posterior gradient paradigm. It was predicted that ADD/H children (N=23) would have more deficits…

A reasonably accurate knowledge of the location of certain learning functions has been achieved through the steady accumulation of data concerning hemispheric specialization. One learning disabilities teacher (van den Honert, 1977) applied hemisphere specialization techniques to eliminate processing conflicts between the hemispheres by sending…

In the neurolinguistic approach to the study of the acquisition of reading and writing, language may be used to express thoughts and intellectual attitudes as well as emotions and emotional attitudes. Experimental studies and clinical data suggest that grammatical rules for spoken language predominantly rely on the left hemisphere of the brain,…

Studies of the brain and of the human culture can be used to demonstrate the limits of traditional approaches (based on psychological perspectives which are often narrow and restrictive) to learning styles and to offer additional perspectives on the complexity of learning. The study of the hemispheres of the brain and its triune nature indicates…

Numerous areas associated with brain dominance have been researched since Bogen and Sperry's work with split-brain patients in the 1960s, but only slight attention has been given to the connection between brain dominance and personality. No study appears in the literature seeking to understand optimal mental health as defined by Maslow's…

Discusses the relevance of the study of the neurobiology of cognitive development, for an understanding of both the neural bases and the nature of cognition. Also considered are the age at which hemisphere specialization first appears and whether hemisphere specialization changes over time. (PCB)

Studies with Nootropic psychoactive drugs (such as Piracetam) suggest that Piracetam lacks significant side effects; promotes memory and learning; and improves the reading ability of dyslexics, possibly by directly affecting the left-brain hemisphere. Results are contrasted with studies showing the lack of effectiveness of intensive teaching.…

Teacher perceptions of the social-behavioral characteristics of 99 boys (aged 7-14) identified by their nonverbal learning abilities found that low nonverbal subjects showed good left-brain functioning, good reading, poor right-brain functioning, poor arithmetic skills, low motivation, poor work habits, disorganization, and poor relationship with…

Noting the lack of experimental evidence substantiating the efficacy of educational strategies designed to exploit the right hemisphere of the brain, a study was designed to assess the cognitive shift model of the Edwards' training procedure. Results showed no difference between the Edwards' procedure and a placebo procedure. Implications for the…

This study presents an empirical investigation of basic processes in the perception of speech sounds. The experimental methods applied have their roots in two different psycholinguistic research paradigms; i.e., "categorical perception" and "dichotic listening." In the categorical perception paradigm, listeners' categorization…

Although it occurs only infrequently in split brain patients, right hemisphere linguistic competence ranges from simple comprehensive skills to a system that can both recognize written and spoken language and produce speech. Such patients are also valuable for the study of global mechanisms, such as those underlying the sense of conscious unity.…

Examined associations between tympanic membrane (TM) temperature asymmetries and biobehavioral attributes of 4- to 8- year-old children. Found shared patterns of associations that linked TM temperature lateralities to individual differences in behavior and socioaffective difficulties. Found that warmer left TMs were associated with affectively…

This paper reviews literature on the use of dichotic stimulation in individuals with mental retardation, and examines how noninvasive dichotic stimulation relates to hemisphere lateralization. Common findings are discussed concerning direction and magnitude of ear asymmetries, patterns of intrusion errors, and speech lateralization of Down…

Results are reported from a study concerned with measurement and analysis of brain hemisphere specialization preferences reported by 126 student teachers. The math/science student teachers expressed hemispheric preferences that differed significantly from the three other student groups (elementary liberal arts, secondary fine arts, and secondary…

Four children, aged 26-41 months, with localized, perinatal brain lesions, were compared to 4 matched controls. With the exception of phonological development, subjects scored below controls on all formal language measures; however, subjects often scored at or above test norms. No score differences were found between right- and left-brain-damaged…
