Popis: Correlative links between psychologic and psychologic indicators were studied in subjects occupied either in airline transportation or in the chemical industry. Investigations covered three groups of persons: managers of airline traffic (57 subjects); workers at "Vratsa" Chemical plant (14 subjects); and operators at "Vratsa" Chemical plant (14 subjects). The psychologic parameters measured included indicators of cardiac variance: mean--mean value of successive cardiac intervals, SD--standard deviation of mean value of cardiac intervals (R-R), AMo--amplitude of the mode, HI--homeostatic index, Pt--spectral power of R-R related to thermoregulation, Pp--spectral power of R-R related to respiration, IBO--index of centralization; psychologic parameters included: extrovertiveness, introvertiveness, neuroticism, psychoticism, interpersonality conflicts, self-control, social support, self-confidence, work satisfaction, psychosomatic complaints. There was evidence of significant and highly significant correlative links between indicators of cardiac variance and psychologic indicators. There thus appeared to exist certain relationships between the psychologic and psychologic levels during lengthy stressful occupational exposure.
