This case exemplifies the principle of levels in the stupor reaction which we have found to be of great value in our study. These levels are correlated with degrees of regression, as a review of the symptoms discussed above may show. In the first place, the dissatisfaction with life, the first phase of regression, leads to the quietness--the inactivity and apathy, which are the most fundamental symptoms of the stupor reaction as a whole. Initiative is lost and with this comes a tendency for the acceptance of other people’s ideas. That is the probable basis for the suggestiveness which we concluded was a prominent factor in catalepsy. Indifference and stolidity may exist with those milder degrees of regression which do not conflict with one’s critical sense, and hence may be present without any false ideas. The next stage in regression is that where the idea of death appears. Although not accepted placidly by the subject, its non-acceptance is demonstrated by the idea being projected--by its appearance as a belief that the patient will be killed. This notion of death coming from without has again two phases, one with anxiety where normality is so far retained that the patient’s instinct of self-preservation produces fear, and a second phase where this instinct lapses and the patient so far accepts the idea of being killed as to speak of it with indifference. The next step in regression is marked by the spoiled-child conduct, interest being so self-centered as to lead to autoerotic habits and the perverse reactions which we call negativism. When death is accepted but mental function has not ceased, the latter is confined to a dramatization of death in physical symptoms or to such speech and movements as indicate a belief that the patient is dead, under the water, or in some such unreal situation. Finally, when all evidence of mentation in any form is lacking, we see clinically the condition which we know as deep stupor and which we must regard psychologically as the profoundest regression known to psychopathology, a condition almost as close to physiological unconsciousness as that of the epileptic.
