R. C. Travis · The Psychological Monographs · 1926
Clinical methods of diagnosis in mental diseases are taking on more scientifically controlled aspects. Especially is this true in the so-called functional neuroses. This study subjected to a certain type of measurement two groups of abnormal individuals, the schizophrenic group and the psychoneurotic. The classical clinical distinction between these two groups is that the schizophrenic is characterized by negativism, restriction of reactions, seclusiveness, emotional and mental deterioration and an introverted viewpoint; while the behavior of the psychoneurotic is characterized by suggestibility, expansion of reactions, overtness, and a correspondence between emotions, thoughts, acts and external conditions.
