Psychophysiological and Some Functional Markers of Mental Workload in Young Men

Resumo

The emotional state of a person affects both the central level and the peripheral indices of the autonomic nervous system, particularly those of the regulation of the heart rate. Our study showed that boys with a higher level of anxiety had higher values of the latent period of the P300 evoked potential and lower indices of short-term auditory memory. Changes in the temporal and spectral components of heart rate variability under the conditions of mental workload indicate that the neurohumoral regulation of the heart rate is shifted toward the suprasegmental influences, including pituitary–hypothalamic and cortical influences.
