less dependent on physiological senescence than on a perceptual frame
of reference having little to do with the physiological changes con-
comitant with aging. ^†
This, however, is a mere supposition. Actually
no further conclusions will be possible until more definite experiments
are made in this area.

As we review the results that have been described in this chapter,
it would appear, in general, that suggestions aimed at altering the
personality of the subject can bring about changes in overt responses,
in responses to such tests as the Thematic Apperception Test and the
Rorschach test, and, to a certain degree, at times in physiological reac-
tions. Evidence increasingly shows that the subject can exhibit two
types of behavioral responses. In one, he "acts out" the suggestions,
or, to use the words of Erickson and Kubie, dramatizes his present
understanding of the suggested situation and of related facts. ^‡ In the
other, the subject undergoes actual changes of a psychophysiological
nature which affect his personality structure and content. In such in-
stances his responses, instead of being the result of acting, are genuine
responses to stimuli as organized by the new personality structure and
content. It should be understood that even in these instances nothing
new is really brought into being in the sense that elements of the
personality already present are utilized. Thus, in induced multiple
personalities the secondary personalities are found to be substructures
of the total waking personality. Again, in regression type III, and
presumably in type II, the younger personality is constructed out of
elements that are part of the older personality. The extent to which
psychophysiological changes can be brought about, and hence to which
the changes may be made genuine, appears to depend directly on the
depth of trance attained, an observation that is not entirely unexpected.
