This article was aimed to propose a new concept on evaluating electromyographic activities of masticatory muscles during chewing movements viewed from the stanclpoint of motor skill. Correlation coefficients between the ratio of lateral distance to ten vertical level set at 0.5rnm to 5.0mm with 0.5mm step from the end of closing phase and activities of bilateral masseter, anterior and posterior temporalis in each chewing stroke were evaluated usiuag raisin, peanut, soft and hard testing gum in five subjects. Habitual chewing side always demonstrated less numbers of subjects who showed high correlation coefficients especially in the case of soft testing gum.
