摘 要:目的探讨恐惧情境下不同心理素质水平军人自主神经反应特点。方法以部队官兵和军校战士学员为研究对象,采用问卷调查筛选被试通过生理心理学实验对不同心理素质水平军人在恐惧以及中性情境下的自主神经反应特点进行研究。结果(1)在中性情绪条件下,低心理素质组[(-0.87±0.64)mmHg]的指端血容振幅(BPV)变化上显著大于高心理素质组[(-0.28±0.24)mmHg];(2)在恐惧情绪条件下,低心理素质组[(0.78±0.11umho]的皮电(SC)的变化显著大于中等[0.22±0.15)umho]与高心理素质组[(0.30±0.12)umho];低心理素质组[(6.54±2.69)nU]的心率变异性(HRV)频谱归一化低频功率(Lfnorm)的变化显著大于中等[(1.32±1.25)nU]与高心理素质组[(3.51±2.28)nU](3)在自主神经反应指标的恢复时间上,低心理素质组[(61.58±35.66)s]在恐惧情绪条件下其心率(HR)的恢复时间显著大于中等[(±36.78±18.58)s]与高心理素质组[(22.36±6.87)s];低心理素质组[(56.87±23.98)s]在恐惧情绪条件下其皮电(SC),皮温(TEMP)、指端血容振幅(BVP),心率(HR)四个自主神经反应指标的平均恢复时间上显著大于高心理素质组[(18.67±9.83)s];(4)在情绪的唤醒度上,低心理素质组(0.88±2.54)在中性条件下其唤醒度的变化明显大于中等(0.57±2.88)与高心理素质组(0.15±1.87);低心理素质组(2.17±2.39)在恐惧条件下愉悦度的变化明显大于中等(1.87±1.45)与高心理素质组(1.24±1.66)。结论 低心理素质军人中性和恐惧情绪反应特点表现为:面临中性刺激或较弱的情绪刺激时,更容易出现生理唤醒以及警觉状态;面临恐惧情绪刺激时,其自主神经活动模式以交感神经系统兴奋为主,生理唤醒状态更强,且这种状态会持续更长的时间并报告更强的痛苦体验。Objective To explore activity characteristics of diverse autonomic nervous system of armymen with diffrent mental quality levels during dread emotion processes. Methods Mental Quality Questionnaire of Armymen was used to select participants. The activilies of the diverse autonomic nervous system of armymen with different mental quality levels during dread emotion processes were discussed by physiological -psychologieal experiments. Results ( 1 ) Under neutral condition hlood vohune 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 nor- malized low frequency spectral component(LF) and skin conductanee(SC) are greater in low mental quality group ((6.54±2.96)nU),(0.78±0. 00) umho) than in moderate((1.32±1.25)uU,((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 reeoveL'y time of skin conductance ( SC ) , skin temperature ( ST ) , hlood 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 significantly greater than the middle ( 1.87 ± 1.45 ) and high psychological quality group ( 1.24 ± 1.66). Conclusion The 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 a
