Since Dax (1865) and Broca (1865) have found that the center of expressive speech exists in the left hemisphere of our brains, many studies have been reported and a variety of research methods have been devised. Especially laterality research in human experimental neuropsychology has contributed to understanding the mechanism of functional hemispheric asymmetries. While neuroimaging techniques such as fMRI, PET, and MEG are mainly employed in contemporary neuropsychology, behavioral methods also have been providing valuable data concerning functional cerebral asymmetries. Divided visual field presentation and dichotic listening have been key behavioral paradigms for laterality research. From the viewpoint of transition of human neuropsychological studies, this article reviews these two key paradigms.
