Abstract
One version of an orthodox rationale for psychological studies of functional hemispheric asymmetry is sketched out. This rationale emphasizes the significance of asymmetry for a psychological taxonomy. An alternative rationale is then presented. This is that the arrangement of the hemispheres with their commissures permits mapping between hemispheres. This mapping may underlie human capacities such as abstraction.
