Let us now consider a number of records which illustrate the expressive movements involved in the process of thinking of such concepts as "up", "down", etc. Their arrangement is identical with the scheme given in figure 5, with the exception that the tapping curves (the sixth and seventh) do not appear. The subject was asked to think of any of the words "up", "down", "right", "left", "yes", "no", etc. He was to begin to conceive them vividly when the command "Now!" was given. This moment is recorded in figures 13 to 15 on the fifth curve. What has been said on page 123 with regard to respiration, holds also in these instances: only the first rise recorded in figure 14 can be regarded as normal. The magnitude of these movements varies between 1/2 and 3 millimeters. The records of the subject whose movements were most extensive, show an average of 1-7/10 millimeter (based on 50 tests), with a mean variation of 6/10 millimeter. Lack of space precludes the reproduction of more than three records. Figure 13 (von Allesch) shows the movement accompanying the thought of "up", a slight raise of the head, recorded in the fourth curve. (The thought of "down" is accompanied by a corresponding downward movement.) [Illustration: FIG. 13.] Figures 14 (von Allesch) and 15 (von Manteuffel) illustrate the nod which is associated with the thought of "yes" in the case of two subjects. It is essentially the same in both: the head is lowered and then raised. The first of the two subjects is more decidedly motor, and his movements therefore were somewhat the more extensive. In the case of the second subject the nod proper is followed by another which is somewhat less extensive. [Illustration: FIG. 14.] [Illustration: FIG. 15.]
