Research supports the premise that various mathematical topics can be categorized as being performed better by the left or right brain hemisphere. Hemispheric lateralization is defined as a learner's preferred hemisphere of control. Torrence's "Human Information Processing Survey" was given to 170 black female college students enrolled in…

A follow-up study was made of cross-sectional research on the development of dichhaptic lateralization. One hundred and eighty students in grades 3, 5, 7, 9, and 11 from two school districts were tested. Participants were 9 boys and 9 girls from each grade level for each district. Subjects were at least 90 percent right-handed, as determined by…

This paper reports a study of cerebral dominance in 42 preschool and kindergarten children. In order to tap left hemisphere functioning, a story of approximately 650 words and 77 specific plot details was composed. Children listened to the 7 minute story and were asked to repeat it. Responses were taped. Tangram pieces were used to assess right…

Finger temperature was recorded bilaterally from 29 right handed test anxious females while they listened to a tape describing test taking situations. Subjects also completed the A-State and A-Trait anxiety inventories, the Test Anxiety Inventory, the Irrational Beliefs Test, and the Differential Personality Questionnaire. A significant…

Differences between left and right hemispheric subjects in recalling information presented as pictures and words were studied. The hemisphericity of 133 college students (37 males and 96 females) was identified using the Human Information Process Survey. These subjects were shown 25 concrete nouns individually either as pictures or words. The data…

There is a growing awareness among researchers that the magnitude of cognitive sex differences is affected by a number of subject variables. To examine spatial and verbal cognitive sex differences as a function of personal and family handedness, the 478 offspring who participated in the Minnesota family study and 454 offspring who participated in…

Whether intuitive abilities can be improved through purposeful training for a more holistic approach to education was the object of this study. It was hypothesized that individuals participating in a mental training program designed to improve right-brain intuitive abilities would show significant improvement in such abilities, while a control…

The study examined the relationship between perinatal stress and decreased right handedness and decreased left cerebral dominance for speech with 215 children born prematurely, followed from birth, and tested at age 5. Results indicated that neither hand preference nor hand performance correlated with degree of perinatal stress and that eye…

Recent research has confirmed that hemispheric patterns of dominance are related to reading skills. Reading is more complex than speech because it includes a visuo-spatial element. In the great majority of people, the left hemisphere deals with speech and sequencing skills. Visual matching of printed words requires the spatial skills of the right…

It was reasoned that if the right ear/left brain hemisphere is more efficient than the left ear/right hemisphere at extracting the meaning of a sentence, then verbatim information presented to the right ear may be more difficult to retrieve than verbatim information presented to the left ear immediately after the sentence is heard. This idea was…

Since past studies have shown that females as well as left-handers do not demonstrate a right-ear advantage for verbal materials, suggesting that linguistic functions may not be handled in the left hemisphere exclusively, a study was conducted to examine these laterality effects more closely. Subjects, 24 undergraduate students at a small college…

Four factors have been reported in the literature as being related to spatial test performance. This study investigated the main and interaction effects of sex, handedness, birth order, and experience on three different types of spatial performance; surface development, object rotation, and coordination of viewpoints. A total of 217 undergraduate…

Despite recent increased attention to Asperger's Syndrome (AS), few psychometric investigations of subjects have appeared and few studies have examined how clinicians and educators might better address the needs of this unique group of people. A diagnosis of AS according to the "Diagnostic and Statistical Manual of Mental Disorders" requires…

Unrealistic personal optimism is the perception that undesirable events are less likely and desirable events are more likely to happen to oneself than they are to happen to other similar people. Three experiments were performed to study the relationships among personal optimism, perceived control, and selective activation of the cerebral…

This report discusses the outcomes of a study of 147 children (ages 7-10) with learning disabilities that investigated the extent to which students legally classified with learning disabilities concurrently manifested mixed lateral dominance (MLD). The study was conducted to determine if MLD was a possible predictive factor for early…
