The topic of whether or not there is a link between language and motor control in left-handed and right-handed individuals remains unanswered. Thirty-four people, fifteen of whom were left-handed and nineteen of whom were right-handed, participated in a study in which they were asked to perform a variety of speech, language, and manual tasks. Their recorded audio and videos were acoustically and perceptually analyzed. Two-way ANOVA and a General Linear Model regression were performed, which showed both manual ability and hand preference (right hand for grasping) affect speech and language production. These results lay the foundation for future research investigating language ability and manual function in adults.
