The "motor tendency of thought" may be ex-
hibited in the case of a normal subject by any of the
usual means for recording "automatisms." For
instance, have the subject's hand resting on a plan-
chette, or, better still, on a glass plate resting on
three steel balls which roll on a second plate, the
upper plate having attached to it a pencil which
bears upon a strip of paper. Have a screen so
interposed that the subject cannot see his hands nor
the pencil and paper. Let him see you trace a line
on the wall in front of him, or hear you describe such
a line verbally. In nearly every case the subject's
hands will move, as shown by the pencil record, in
a way corresponding to the line.

Buckle a strap around the subject's head (over
the top of the head and under the chin), and fasten
to the strap on top of the head a wooden point.
Let the subject stand (with eyes closed) under a
sheet of smoked paper supported at one edge and
resting on the wooden point. Tell the subject to
stand perfectly still, and mention to him interesting
objects actually or suppositionally lying in certain
directions from him, and he will be found to move
in the designated direction, or the opposite, accord-
ing to the nature of the object.
