The present study investigated empirically whether condensation-like phenomena, as measured by boundary disturbances, are a reliable and intemallyconsistent phenomena in the dreams, Rorschach responses, and preconscious perceptions of the same individual. Subjects kept dream logs for two weeks and were administered the Rorschach and a subliminal perception task which involved the presentation of both a subliminal and supraliminal stimulus. Visual condensation was positively correlated for the dream and Rorschach protocols on most measures. Further, Rorschach boundary disruption was significantly associated with the amount of incorporation of the subliminal stimulus in subjects' drawings of the supraliminal stimulus. These results suggest that primary process mechanisms are evident in both conscious and nonconscious mentation and support a reconceptualization of primary process in terms of actual perceptual mechanisms which is of potential heuristic value in the empirical elucidation of dreams, creativity, and preconscious perception.Traditionally, primary process has referred to a qualitatively unique form of cognition responsible for the more colorful, disturbing, and elusive aspects of the human experience [I, 2], including such diverse phenomena as dreams [3], symptom formation [4], creativity [5][6][7][8][9], and disordered thought [10). While early theorists characterized primary process thought as regressive, chaotic, and gratification-seeking, contemporary theorists have emphasized such mechanisms as information-processing and parallel-distributed processing in reformulating primary process as a purposeful, dynamic, and organized cognitive modality 15
