Abstract:
ObjectiveTo explore activity characteristics of diverse autonomic nervous system of armymen with different mental quality levels during dread emotion processes.MethodsMental Quality Questionnaire of Armymen was used to select participants.The activities of the diverse autonomic nervous system of armymen withdifferent mental quality levels during dread emotion processes were discussed by physiological - psychological experiments.Results ( 1 ) Under neutral condition blood volume pulse (BPV) is greater in low mental quality group( ( -0.87 ±0.64)mm Hg) than in high( -0.28 ±0.24)mm Hg).(2) During dread emotion processes the normalized low frequency spectral component(LF) and skin conductance (SC) are greater in low mental quality group ( (6.54 ± 2.96) nU),(0.78 ± 0.11 ) umho) than in moderate ( ( 1.32 ± 1.25 ) nU,( (0.22 ± 0.15 ) umho) and high ((3.51 ±2.28 )nU,((0.30 ±0.12) umho).(3) During dread emotion processes the recovery time of HR and the average recovery time of skin conductance( SC ),skin temperature( ST),blood volume pulse(BVP) and HR are greater in low mental quality ( 61.58 ± 35.66 ) s,( 36.78 ± 18.58 ) s ) than in high ( ( 22.36 ± 6.87 ) s,(56.87 ± 23.98 ) s).(4) In emotional arousal,and low mental quality (0.88 ± 2.54 ) in neutral conditions change their arousal'was significantly greater than the middle (0.57 ± 2.88) and high psychological quality group (0.15 ± 1.87) ; Low mental quality group (2.17 ±2.39) under the conditions of pleasure in the dread was significantlygreater than the middle ( 1.87 ± 1.45 ) and high psychological quality group ( 1.24 ± 1.66).ConclusionThe findings indicate that armymen with low mental quality is more likely to show corresponding physiological arousal and alert status in face of the neutral or weak emotional stimuli.When facing dread emotional stimuli,they would show stronger physiological arousal mainly basing on the excitement of sympathetic nerve system,and such statuswould last much longer to bring about more fierce pain experience.
