"Binaural integration listening test" proposed by Arai et al. (2009) explores cerebral asymmetry of speech perception by using the stimuli where phonemic and prosodic information of speech is separated from each other. These two information are then allocated to either right- and left-ear and presented to the listeners simultaneously, so that the selective attention of the auditory system can be investigated. In this study, we conducted three experiments; the first experiment examined the appropriateness of the methods for creations of the stimuli; in the second and third, that of the experimental tasks was tested. the results confirmed the adequacy of the stimulus creations, although we may need further deliberations on the experimental tasks.
