States that hemispheric preference literature reveals mostly marginally significant data--different ways of probing human thought processing exist and various mistakes can sometimes account for borderline data. Elaborates the Sonnier Model of Hemispheric Preferences (SMHP) which may provide clarification and more fruitful research questions and…

This article provides an overview of decision-making literature, describes individual and organizational decision stages, and reviews selected idiographic influences on decision-making. Also presented is a model for predicting and explaining variations in decision outcomes. These outcomes include affective, cognitive, and behavioral conditions.…

Observed 4-year-olds during interaction tasks, and 2-weeks later recorded brain wave functions while subject attended to a visual stimulus. Found that children who displayed social competence exhibited greater relative left frontal activation than children displaying social withdrawal during the play session, who exhibited greater relative right…

New evidence on brain functions demonstrates the necessity of connections between knowing and doing, school and life, knowledge and application, and content and context. Contextual teaching and learning principles can better harness the power of the thinking brain. (SK)

Responds to L. Eubank and K. R. Gregg article (this issue), suggesting they have misinterpreted and misrepresented claims made by B. Jacobs and J. Schumann. Claims discussed include the micro- and macro-organization of neurobiology and language, the Explananda, Jacobs and Schumann's acquisition mechanism, and reductionism. The single acquisition…

Responds to L. Eubank and K. R. Gregg article (this issue), negating their rejection of neurobiological accounts of language acquisition because they are not based on Government and Binding theory and addressing their ideas on the explanatory power of associative learning. A discourse between neurobiology and linguistics is possible only if…

Describes an assignment that begins with a short questionnaire to determine students' dominant mode of thinking. Discusses differences between left- and right-mode thinking patterns and how communication is affected by domination of either mode. (SR)

Illustrates the technique of mind mapping as applied in executive education and management development. Indicates that most of the 70 students surveyed appreciated its use for recall and creative thinking, although some prefer a top-to-bottom, linear outline approach. (SK)

Electroencephalographic power spectra were studied in two poor-reading adolescent groups (n=38), dysphonetic and phonetic. Significant Group x Hemisphere effects were found in the alpha and beta bands, with the phonetic group showing right greater than left asymmetry. Results suggest more circumscribed and mature processing in the phonetically…

Adults (N=58) with attention deficit hyperactivity disorder and 29 age-and education-matched controls were evaluated for right hemisphere dysfunction. Findings support the concept of right hemisphere dysfunction in a subset of patients with ADHD, although this subset did not represent a distinct clinical subgroup in terms of medication response,…

A large orthographic neighborhood (N) facilitates lexical decision for central and left visual field/right hemisphere (LVF/RH) presentation, but not for right visual field/left hemisphere (RVF/LH) presentation. Based on the SERIOL model of letter-position encoding, this asymmetric N effect is explained by differential activation patterns at the…

Studies on functional hemispheric asymmetries have suggested that the right vs. left hemisphere should be predominantly involved in low vs. high spatial frequency (SF) analysis, respectively. By manipulating exposure duration of filtered natural scene images, we examined whether the temporal characteristics of SF analysis (i.e., the temporal…

In her critique of emotional intelligence (EI) theory and research, Waterhouse (2006) makes several claims. First, she argues that there are "many conflicting constructs of EI," implying that it cannot be a valid concept given this multiplicity of views. Second, she cites some research and opinion suggesting that "EI has not been differentiated…

Previous investigations comparing auditory event-related potentials (ERPs) to words whose meanings infants did or did not comprehend, found bilateral differences in brain activity to known versus unknown words in 13-month-old infants, in contrast with unilateral, left hemisphere, differences in activity in 20-month-old infants. We explore two…

It is widely accepted that the cerebellar and basal ganglia control circuits contribute to the programming of movement. Converging evidence from neuroimaging, limb control, and neuropsychological studies suggests that (1) people with cerebellar disease have reduced ability to program movement sequences in advance of movement onset and (2) people…
