The need to supplement clinical with experimental-normal studies of hemispheric asymmetry.
It is argued that in spite of the methodological and interpretive problems with them, experiments on laterality in normal subjects must continue in view of other problems with direct neuroclinical investigations. A variety of such problems are listed, ranging from the relative paucity of the potential subject population to the difficulty in inferring normal function from damaged brains. The main justification for such studies must be the possible amelioration of the lot of brain-damaged patients and improvement of their treatment rather than scientific curiosity.
