Book excerpt: Excerpt from Harvard Psychological Studies, Vol. 4 In two previous articles upon the negative instruction the main interest was directed toward the effect of such instruction upon the suppression of imagery and the muscles of the vocal organs. The work described in the present article was undertaken in order to obtain an analysis of the process of executing a skillful movement, that is, a movement requiring perfect motor control, under the conditions of positive and negative instruction. The experiments were conducted in the Harvard laborer tory in the spring of 1912 upon five subjects referred to as A, B, C, D, and E. They were all graduate students with a training in experimental methods. The instrument used was a tracing board similar to the one recommended by Whipple. The subject passed the wire attached to the stylus through his coat sleeve, so that it would move freely with his arm and not interfere with its movements. He sat before a table of convenient height with the board directly in front of him. The positive instruction given him was: "Go down the middle of the groove." When the stylus touched the sides a telegraph sounder indicated the contact. The precautions advised by Whipple were observed.
