Abstract
The two well known dichotomies in hemispheric functions–temporal-spatial, and analysis-synthesis (extraction-integration)–are combined in a unified theory of cerebral dominance. The two dichotomies are first considered within the framework of a two-stage model of information processing, and subsequently reduced to the extraction and integration operations performed at each of the two stages. At the first stage, the respective operations of extraction and integration applied on the sensory stream yield the spatiotemporal organization of events. At the second stage, these operations are expressed in progressively more complex organizations such as verbal coding and pictorial imagery. The model is finally generalized into a multiple-stage model. Some empirical consequences are derived.
