While advanced neuroimaging methods such as functional magnetic resonance imaging (fMRI) provide a reliable way to determine individual lateralization of function, these methods are costly and not readily available to every scientist interested in investigating functional hemispheric asymmetries in humans. Behavioral methods of testing humans provide cheaper and easily administered alternatives to fMRI scans and are still widely used in lateralization research today. In the following chapter, two key methods will be reviewed: divided visual field paradigms based on tachistoscopic viewing and the dichotic listening task.
