EEG asymmetry as a function of occupation, task, and task difficulty.

Nine male artists and eight male engineers were tested for asymmetry of occipital alpha as a function of occupation, lateral speicificity of task, and difficulty of the task. NEbes' ring test and a facial memory test were used as “right hemisphere” tasks, and linguistic and mathematical tasks were chosen as left hemisphere specific. Results found no difference on the basis of occupation or difficulty, and significant results were found for task laterality.
