Relationship between Neuroticism Level and Results of Goal-Directed Behavior in Humans As Observed in the Model of Basic Endosurgical Training

详细

The dynamics of heart rate variability (HRV), electromyography (EMG), and personal endoscopic success were studied in subjects with different extents of neuroticism. The study involved 87 men aged 18–24 years. A pronounced success in endosurgical training was typical of subjects with lower neuroticism scores, reflecting the quality of acquired motor stereotypes. An increase in the lengths of RR intervals during training was characteristic of subjects with higher neuroticism scores. Endosurgical simulator training was accompanied by an increase in the power of the HF-range in the low-neurotic subjects, while the parameter decreased in the high-neurotic subjects. Specific features of physiological support of goal-directed activity in the model of endosurgical training were established for subjects with different extents of neuroticism. The low-neurotic subjects were characterized by an increase in parasympathetic influences on the heart function during goal-directed activity in the model.
