This study was undertaken to explore various fundamental characteristics of the cyclothymic personality type. The subjects were 474 students who were classified into three basic personality types -cyclothymic, schizothymic and collathymic- on the basis of their performance on the VERAC Personality Inventory (VPI). Analyses of two questionnaires (TSPS and Self-Differential) completed by the subjects indicated that students classified as cyclothymic had a stronger tendency to recognize their own personality type and to adjust images which could or might be recognized by others. To explore the cyclothymic personality in greater detail, this group was classified into two sub-types -hypomanic and immodithymic types- and two additional tests (EPPS and EFT) were administered to these subjects. Analysis of the responses to these tests revealed that (a) the differences between the two sub-types in EPPS coincided to some degree with earlier reports in the clinical literature, (b) there was no difference between the sub-types in terms of reaction time or number of errors in EFT, and (c) the differences obtained between EPPS and EFT were not so clear as those obtained among the three basic personality types. Overall, these results supported the contention that cyclothymic personality type is a viable sub-category in personality type theory.
