Objectives: The purpose of this study is to investigate the relationship between the extent of prolongation in P300 latency by sleet deprivation and personality variables.
Methods: Eighteen healthy male college students participated in this study. Subjects remained wake for 37 hours under conti nuous surveillance. In the morning and evening of two consecutive study days, P300 was checked four times. MMPI and STAIT were checked in the morning of the first day. The 18 subjects were divided into two groups according ttheir extent of P300 prolon gation by sleep deprivation: Group A consisted of short P300 latency prolonged subjects, and group B of long latency prolongec subjects. The MMPI profiles and STAI-T scores of these two groups were compared .
Results: Group B stowed significantly higher scores in the Mf subscale (t -2.16, df=16, p=0.046) and Pa subscale (t=-2.61, df=16, p=0.019) than group A. Group B also showed higher F subscale scores at a marginally significant level (t-2.11, df=16, p=0.052).
Conclusion: These results suggest that subjects with higher scores in F, Mf, and Pa subscales tend to have delE red cognitivE process and decreased efficiency of mental process by sleep deprivation. It can be hypothesized that individuals who are sensitive passive, dependent, and easily projecting´are susceptible to the deterioration of cognitive function by total sleep deprivationSleep Medicine and Psychophysiology 2003 ; 10(1) : 61-66
