NREM MENTATION - RELATION TO PERSONALITY ORIENTATION TIME AND TIME OF NIGHT

20 YOUNG ADULT MALES SLEPT IN THE LABORATORY ON 2 NONCONSECUTIVE NIGHTS DURING WHICH CONTENT RETRIEVAL AWAKENINGS WERE MADE IN PERIODS OF NREM SLEEP. SS ALSO COMPLETED SEVERAL PERSONALITY MEASURES (CPI, MMPI, TAT). THE STUDY EXAMINED (1) PERSONALITY CORRELATES OF NREM MENTATION, (2) THE RELATIONSHIP BETWEEN LATENCY OF RESPONSE (ORIENTATION TIME) UPON AWAKENING FROM SLEEP AND THE NATURE OF THE SUBSEQUENT REPORT, AND (3) QUALITATIVE CHANGES IN NREM REPORTS OVER THE COURSE OF THE NIGHT. EARLIER OBSERVATIONS ON THE INCIDENCE OF NREM MENTATION AND THE POSITIVE CORRELATION OF ITS DREAMLIKE QUALITY WITH TEST INDEXES OF PERSONALITY DISTURBANCE WERE CONFIRMED. DREAMLIKE REPORTS WERE MOST LIKELY TO HAVE OCCURRED ON NREM AWAKENINGS WITH THE SHORTEST ORIENTATION TIMES. NREM IDEATION BECAME MORE DREAMLIKE OVER THE COURSE OF THE NIGHT. (24 REF).
