Dissociations Between System 1 and System 2

Abstract

Calculation ability represents an extremely complex cognitive process. It has been understood to represent a multifactor skill, including verbal, spatial, memory, and executive function abilities. In this chapter, we will deal with it by calculation disturbances are analyzed. Specifically, evidence from brain-damaged patients indicates that deficits in mathematics can follow injury to either cerebral hemisphere, but that the nature of the impairment will differ depending upon the locus of the cerebral insult.
