(11) The direction of the stimulus with respect to the normal position of the body also seems to have something to do with the regularity of the response, and with the general forward or backward tendency. Tactual surfaces applied or tones sounded behind the subject do seem to make the bodily adjustment more confused, and less pleasant. All that subjects could say was that the position was felt as abnormal and correspondingly less pleasing.
(12) In many unpleasant feelings, where there was no specific localization possible, the "stiffening tendency of hardening one's self to a necessary experience" was frequently reported. In the case of other states of undifferentiated pleasure a "consenting bending forward of the whole body" was often detected.
(13) Many stimulations seem to demand that one draw one's self erect, square the shoulders, and "assume the attitude of alertness."
(14) Certain colors for almost every subject independently hint at sea-sickness. Others, as noted above, report the incipient suggestion of nausea in the digestive tract. Indeed, abdominal references are frequently reported by most of the subjects. The abdominal muscles become "eased up," or again there is a "sucking-in of the belly."
(15) The feeling of "being natural," of regularity, a universally popular feeling, is described as a pleasant relief from all tensions and habitual inhibitions, or a dropping of one's characteristic muscular tonicity.
(16) Other stimulations still, particularly certain delicate odors, for men, subjects C and E for example, seem to suggest what they call the "childish play impulse." They are called "simple, foolish, childish pleasures," ignored in ordinary life. They are slightly pleasantly irritating, and merely make one wish to do something. It is pure bodily restlessness, a general kinæsthetic enjoyment. Three subjects, especially, find here the frequent twitchings in the calves of the legs, in the knee-cap, and the more decided innervations which contract the tendons of the thighs and hips.
(17) Subject I frequently detected sensations of contraction in the tensor tympani connected with the pleasure derived from high tones. Others referred feelings for tones partly to the regions of the ears.
(18) The kinds of facial references are numerous. General contraction or expansion around the eyes, forehead, temples, sometimes to the whole head, and quite frequently it seemed as if the feeling referred to the very inside of the eyeball, to the iris and accommodation movements.
(19) Subjects A, D, F, and K noted specific incipient tendencies to smile, to smooth the brow, and to "unbend the face" as characteristic descriptions of certain oft-repeated experiences.
(20) Introspections from subjects F and G quite constantly revealed articulatory impulses vividly accompanying the feelings for many colors and forms.
