attempts during the period when she shouted like a huckster, giving no evidence whatever by her expression or the tone of her voice of feeling anxiety, sorrow or any other normal emotion. All these queer and larval affective reactions remind one strongly of dementia præcox. The resemblance of the benign stupor to certain dementia præcox types is not merely a matter of identity with catatonic features (catalepsy, negativism). In these anomalous mood reactions it seems as if there were a definite dissociation of affect, and so there is. How then can we differentiate these emotional symptoms from the “dissociation of affect” which is regarded as a cardinal symptom of dementia præcox? The answer is that this term is used too loosely as applied to the latter psychosis. It is a particular type of dissociation which is significant of the schizophrenic reaction, for in it there is an acceptance of what should be painful ideas evidenced either by incomplete manifestations of anxiety or depression or actually by smiling. We never see in dementia præcox the reverse--a painful interpretation of what would normally be pleasant. It is the pleasurable interpretation of what is really unpleasant that gives the impression of queerness in the mood of these deteriorating or chronic cases. In stupor, on the other hand, although this dissociation takes place, the mood is never inappropriate, merely incomplete in that all the components or the full expression of the normal reaction are not seen. Our description of the mood reactions in stupor would be incomplete if we omitted to mention the occasional appearance of an emotional attitude not unlike that seen in many cases of involution melancholia, which reminds one in turn of the reactions of a spoiled child. The commonest of these manifestations is resistiveness that may occur when an examination is attempted, feeding is suggested, or a sanitary routine insisted upon. One also meets with resentfulness. One patient, who frequently showed this reaction, explained it retrospectively by saying that she wanted to be left alone. Quite analogous to this is sulkiness that occasionally appears. Then we have, particularly as recovery begins, other childish tricks, such as flippancy in answering questions or the playing of pranks. Such tendencies naturally lead over to frank hypomanic behavior.
