Left-handers with an inverted handwriting posture were compared with other left-handers and with right-handers on a spatial reasoning test. Results were consistent with the hypothesis that left-inverted subjects had relatively bilateral representation of verbal and spatial functions. Bilateral representation is assumed to be inefficient.…

First-, third-, and fifth-grade children and adults performed a tactile shape-discrimination task. Changes in the magnitude of differences between performance in the left and right perceptual fields were examined. Results suggested that the right hemisphere becomes progressively more specialized for tactile spatial ability with increasing age.…

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…

This bibliography cites references dealing with background material on the functions of the human brain and current research on sex differences in brain development. A list of 10 books published since 1974 is followed by a more extensive annotated bibliography of 29 articles, and a bibliography of 19 reports, complete with ERIC reference numbers…

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…

Relationships among the scales of the Myers Briggs Type Indicator and the Human Information Processing Survey revealed in a study by S. C. Shiflett (1989) were reinvestigated in a study involving 554 college students (270 males and 284 females). One significant gender difference among the correlations was found. (SLD)

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 describes some current research which links selected aspects of brain research to selected issues in education. These issue areas include: (1) the relationship between neurophysiology and cognition; (2) the implications of cerebral lateralization for creativity, imagery, and art education; (3) sex differences in brain functioning; (4)…

The mental development of 332 preschool-age children with orthopedic disabilities was assessed at a children's hospital over a 10-year period, and comparisons were made for right-handed and left-handed. The left-handed children were slower than right-handed children in learning speech and language skills (Author/SEW)

According to A. R. Luria (1973) the cerebral organization of mental activity can be understood through analyzing how mental activity is altered in different local brain lesions. Recent brain function research has used this approach in locating areas of the brain involved in specific processes. This study recognized the importance of this method…

This study was designed to consider effects of age, sex, intelligence, lateral usage, and lateral awareness on young children's performance of spatial organization tasks. The sample consisted of 79 Caucasian, middle socioeconomic status nursery school children (mean C.A. 57.80, S.D. 4.47 months), 44 boys and 35 girls. Spatial organization was…

The cognitive processing strategies of two groups of French-English bilinguals were studied by means of an auditory Stroop test designed to evaluate cerebral hemispheric involvement. An "early bilingual" group were bilingual before the age of five, and a "late bilingual" group were bilingual after the age of ten. Stimuli were…

Relationships between brain-lesion location and behavior in 33 males and 31 females with unilateral lesions were studied. Statistical tests suggest that a single model can describe the relationships for females, but in males separate models of the relationships between lesion location, verbal intelligence quotient, and performance intelligence…

Implications of two studies conducted by the Institute for Human and Machine Cognition (IHMC) at the University of West Florida (Pensacola) regarding electrophysiological determinants of cognitive style (CS) are discussed. Most of the IHMC's research focuses on bimodal processing theory, according to which the human brain has at least two…
