Conference paper


Researchers in the past few decades have successfully employed electroencephalograms (EEGs) in their investigations of cerebral lateralization of mental functions [1–3]. For example, when the brain waves of a subject engaged in a spatial-oriented task (e.g., manipulating blocks to reconstruct a pattern from memory) are monitored, a decrease in alpha waves in the right hemisphere is seen, indicating activation of the right side of the brain during that task. Similarly, the left hemisphere usually shows decreased alpha-wave activity during a task that is more verbally focused. Also, the left and right cerebral cortex contribute differentially to the regulation of emotion. For example, greater left-frontal activation has been associated with reports of more intense positive affect in response to positive film clips, whereas greater right-frontal activation has been associated with more intense reports of negative affect in response to negative film clips [4].
