This paper describes a series of preliminary and a double blind study on crossed visual laterality and reading difficulties in children. Preliminary studies investigated handedness, eye preference, and ear preference in a total of 196 third and fifth grade students. About 42 percent of the tested students were identified with the Monahan/DeYoung…

Identifies three main strengths of Casey's spatial ability model, but notes that a study by McKeever found different results concerning the relationship between familial handedness and females' mental rotation ability. Considers the use of a familial handedness measure to be a weakness of the model because handedness might not be an inherited…

The use of sign language is suggested as a way to stimulate and educate the right brain, thereby cultivating student creativity. Sign language's benefits are that it forces the hearing person to think differently, can add clarity to oral communication, and could be applied to help children with learning disabilities. (JDD)

This article reviews the work on patients who have undergone partial or complete brain bisection and addresses the concept of modularity from three different perspectives: (1) structure-function correlations; (2) modular components of cognitive processes; and (3) integration of modular processes. Several brain pictures and diagrams are presented.…

Examines hemispheric differences in cortical arousal as a function of positive and negative emotional television scenes. Finds that (1) the processing of emotional content is hemispherically asymmetric; and (2) negative material produced greater cortical arousal in the right hemisphere and positive material greater arousal in the left. (MS)

Tests a theoretical model of hemispheric brain activity which attempts to explain the relation between visual ability and verbal written compositions. Concludes that the model which indicates that synthesis is a right brain activity and that visualizing activity can assist synthesis is supported for right-handed students. (RS)

Obtained Wechsler Adult Intelligence Scale intelligence quotient (IQ) data from 64 patients with cortical neoplasms confined to one brain quadrant. Indicated significant effect for lesion laterality for verbal IQ scores and verbal IQ-performance IQ difference scores. Found no significant main effect for gender or lesion site (anterior-posterior)…

This article discusses the hypothesis of unilateral left hemisphere damage as an explanatory model for the neurological basis of specific language impairment considering both evidence challenging the theory as well as evidence supporting it. (Author/DB)

Evidence that the vigor of the startle reflex varies systematically with the organism's emotional state is reviewed. A theory elucidating this relationship suggests how amplitude of eyeblink response to a probe may be modulated by affective content of perception and thought. Implications for research on emotion are outlined. (SLD)

Describes instructional strategies and activities to help students learn about brain structure, development, and function. Lists five resources. (eight references) (JRH)

In comparison to infants of mothers who had no symptoms of depression, infants of mothers with symptoms exhibited reduced left frontal lobe activity during play and failed to exhibit increased right frontal lobe activity during distress. Infants of symptomatic mothers showed less distress during maternal separation than infants of nonsymptomatic…

This article describes the development of a metaphorical whole brain model and its application to Applied Creative Thinking (ACT) Workshops to enhance individuals' capability for full creative functioning. The design of ACT workshops, the learning model used, and workshop components are described. (JDD)

This article presents evidence that initial and advanced reading abilities are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left hemisphere reading strategies or later failure to shift from earlier right hemisphere strategies are hypothesized as resulting in two different types of dyslexic…

This article reviews the history of the neuroscientific study of language, examining research on three main issues: (1) the neurofunctional differences between primary language acquisition and second-language acquisition; (2) the critical period issue; and (3) the role played by the right hemisphere of the brain in language acquisition. (140…

Verbal and musical stimuli were presented to infants in a study of the relations of evoked potential left-right amplitude asymmetries to gender and hand preference. There was a relation between asymmetry and hand preference, and for girls, between asymmetry and stimulus condition. Results suggest a gender difference in cerebral hemisphere…
