Abstract
Hemispheric lateralization of alpha band power in the temporal (T3/T4) EEG was studied in 11 subjects, 5 females and 6 males, performing 7 tasks, including Block Designs, Mental Letter, Embedded Figures Test, and Rod and Frame Test. Each block of 7 tasks was repeated 4 times. The findings indicate that, depending on the task, males are more consistently right-or left-lateralized, than females. While males tend to adopt consistent processing strategies on tasks such as Block Designs, the Rod and Frame Test, or Mental Letter, females fail to show consistent lateralization across replications. The findings are intepreted in terms of the effects of socialization on both task performance and cerebral lateralization.
