Hemispheric Specialization, Handedness, and Laterality
Until recently it was thought, perhaps simplistically, that a right-handed person was necessarily left-hemisphere dominant for language, and similarly a left-handed person was right-hemisphere dominant for language. Now it is known, from neuropsychological researches over the last 40 years, that this is not so and that the whole question of the relation between handedness and hemispheric specialization is highly complex and variable within certain limits. Before we examine the relationship between cerebral function and handedness, however, let us look at these two behavioral processes separately.
