Present study was performed to examine the effects of instructions designed to encourage the awareness of the internal control process on the acquisition of voluntary control of a novel muscular activity. The m. auricularis posterior(the muscle which draws an auricle backward) was selected as the object of the experiment. Twenty-four undergraduate and graduate students who could not move their auricles were required to activate their left m. auricularis posterior and underwent rest, pretest, training, and posttest sessions. They were assigned to one of three groups, i. e., a group BF who were provided with electromyograph (EMG) feedback signals from the left m. auricularis posterior on all training trials, a group NF who were provided with no such information on any training trials, and a group SBF who, in order to encourage their awareness of the experiencing, were provided with EMG feedback at their request on each training trial and asked some questionsabout ways and feelings of striving to activate the left m , auricularis posterior, a bodily feeling brought about by striving, and how to use the feedback signal on every three training trials. Main results were as follows : (1) Mean percentage increase of integrated EMG in the left m. auricularis posterior from pretest to posttest were almost significantly greater for the group SBF than for the gorup BF, and for the group BF than for the group NF. (2) The number of subjects who could learn to move their auricles in the group SBF was also more than that in the other two groups. (3) Only for the group SBF, all subjects knew correctly whether they could move their aurilcles after the experiment. These results provided evidence supporting the hypothesis of the present study that subjects could aquire voluntary control of a novel muscular activity more effectively by being encouraged in their awareness of the internal control process.
