A study involved the development and testing of a theoretical framework of cerebral specialization in which each hemisphere of the brain is viewed as an independent information processing system. During the study, four sets of experiments were conducted. These involved behavioral as well as electrophysiological measures. According to the researchers' model, any given set of tasks can overlap partially, completely, or not at all in terms of the resources required from a particular hemisphere. Among the conclusions reached during the study were the following: (1) data from the experiments support the idea that there are at least two types of resource supplies that are associated with processing in the left or right hemispheres; (2) the resource supplies of the left and right hemispheres are independent and have implications for both cerebral specialization and divided attention issues; and (3) according to data from the electrophysiological experiments, gender seems to play an important role in the organization and utilization of cerebral resources.
