title: [Factor analysis of the structure of nocturnal sleep and the results of psychodiagnostic examination in man].
abstract: Factor analysis was carried out of sleep structure and results of complex psychodiagnostic study in 35 subjects. Seven orthogonal factors were singled out. It is shown that alarm level is connected with fast sleep general presentation; the system of psychological defences is linked with the fast sleep in the second cycle; the self-control in alert state and the transfer from alertness to sleep are interrelated, and duration of the first and last sleep cycles are reciprocally connected.
