Inferred Hemispheric Thinking Style, Gender, and Academic Major among United Arab Emirates College Students

To examine the relationships between the inferred hemispheric chinking style, gender, and academic major, 190 undergraduate men and women in social science and applied science classes were administered the Your Style of Learning and Thinking to assess their thinking styles. Although endorsements of an integrated style were highest for all subjects, analysis indicated men tended to endorse the right-hemisphere style items in processing information more than women, while the latter tended to endorse items of an integrated style in processing information. Applied science majors appeared to endorse items of a more right-hemisphere style in processing information than social science majors. These results were discussed in view of contemporary biological, psychosocial, and educational perspectives.

ABSTRACTReceptive fields (RFs) processing information in restricted parts of the visual field are a key property of neurons in the visual system. However, how RFs develop in humans is unknown. Using fMRI and population receptive field (pRF) modeling in children and adults, we determined where and how pRFs develop across the ventral visual stream. We find that pRF properties in visual field maps, V1 through VO1, are adult-like by age 5. However, pRF properties in face- and word-selective regions develop into adulthood, increasing the foveal representation and the visual field coverage for faces in the right hemisphere and words in the left hemisphere. Eye-tracking indicates that pRF changes are related to changing fixation patterns on words and faces across development. These findings suggest a link between viewing behavior of faces and words and the differential development of pRFs across visual cortex, potentially due to competition on foveal coverage.

Load Conditions

This study investigated hemispheric lateralization in comprehending and evaluating lecture material with and without nonverbal hand gestures. Participants watched a lecture with and without gesture under conditions of cognitive load in the left or right hemisphere. There were no effects of gesture or load on lecture comprehension, but gesture and load influenced how participants evaluated the lecture. Specifically, presence of gesture significantly influenced participants’ affective evaluations of the lecturer in both load conditions. However, gesture influenced cognitive evaluations of the lecture material only when the right hemisphere was free from cognitive load. The results suggest that the right hemisphere may be specialized for processing information conveyed through hand gestures.

We report a 68-year-old right-handed female who was admitted to our hospital complaining chiefly of incontinence and decreased activity. Her brain images showed characteristics of Marchiafava-Bignami disease, such as symmetrical abnormal signals localized in the corpus callosum. The patient had no drinking habits. Her past medical history included total gastric resection to treat gastric cancer. On hospital admission she was markedly underweight. This appeared to be a rare case of Marchiafava-Bignami disease not attributable to heavy drinking and occurring in a state of malnutrition. Evaluation of callosal dissociation symptoms produced findings indicative of such symptoms. She showed a marked difficulty in writing dictated single words and short sentences in Japanese alphabetic characters, especially with her left hand. In contrast, writing dictated words in Chinese characters (also used in written Japanese) was affected in both hands, with different types of dysgraphia seen in the right and left hands. The agraphia in the left hand seen in this patient appears to have occurred as a result of the language faculty of the left hemisphere failing to be transmitted to the right brain, while agraphia in the right hand may have occurred as a result of spatial processing information in the right hemisphere failing to be transmitted to the left hemisphere.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.

Hemisphere Specialization

Previous studies often revealed a right-hemisphere specialization for processing the global level of compound visual stimuli. Here we explore whether a similar specialization exists for the detection of intersected contours defined by a chain of local elements. Subjects were presented with arrays of randomly oriented Gabor patches that could contain a global path of collinearly arranged elements in the left or in the right visual hemifield. As expected, the detection accuracy was higher for contours presented to the left visual field/right hemisphere. This difference was absent in two control conditions where the smoothness of the contour was decreased. The results demonstrate that the contour detection, often considered to be driven by lateral coactivation in primary visual cortex, relies on higher-level visual representations that differ between the hemispheres. Furthermore, because contour and non-contour stimuli had the same spatial frequency spectra, the results challenge the view that the right-hemisphere advantage in global processing depends on a specialization for processing low spatial frequencies.
