目的 探讨不同心理素质水平军人在恐惧情绪刺激下采用减弱情绪调节策略时自主神经反应特点。方法 采用军人心理素质量表从驻渝部队官兵中整群抽取841人为被试,根据军人心理素质量表评价标准,筛选出不同心理素质水平官兵共90名,其中高、中、低心理素质军人各30名。采用2份情绪视频材料,诱导被试的恐惧情绪,并利用八通道多参数生物反馈仪,记录在情绪减弱调节下自主神经反应及其相应的平均恢复时间。结果 (1)在恐惧情绪诱发条件下,低心理素质水平军人采用认知忽视调节策略时,其指端血容振幅(BVP)变化值 [(5.47± 6.33) mmHg, 1 mmHg=0.133 kPa ]大于中、高心理素质水平军人 [(1.26±2.54;0.94±3.10) mmHg, P<0.05 ];高心理素质水平军人采用认知忽视调节策略时,其心律R-R间期标准差(SDNN)变化值 [(52.23±47.30) ms ]大于采用此策略的低心理素质水平军人 [(3.31±17.69) ms, P<0.05 ]。(2)高心理素质水平军人采用简单观看策略时,BVP的恢复时间26.00±43.84) s ]长于采用表情抑制策略组 [(23.50 ±34.96) s ]和采用认知忽视策略组 [(22.00±36.15) s, P<0.05 ],同时,其皮电(SC)恢复时间 [(106.50±20.28) s ]也长于低心理素质水平军人 [(103.00±37.73) s, P<0.05 ]。(3)高心理素质水平军人采用认知忽视情绪调节策略时,SC恢复时间(68.50±49.39) s ]短于中、低心理素质水平军人 [(106.50±24.95;118.00±4.22) s, P<0.01 ]。(4)采用表情抑制情绪调节策略来减弱恐惧情绪,高中低心理素质军人无明显自主神经反应差异。结论 认知忽视情绪调节策略更有利于高心理素质军人降低其恐惧情绪,表现为高心理素质军人交感和副交感神经调节能力强于中低心理素质军人。 |

Abstract: |
Objective To investigate the characteristics of autonomic nervous responses to down-regulating emotion strategy in servicemen with different mental qualities and exposed to fear emotion. Methods Mental Quality Questionnaire of Armymen was employed to select participants from 841 servicemen from Chongqing, among whom 90 participants were randomly selected, including 30 with high mental quality, 30 with moderate mental quality and 30 with low mental quality. Fear emotion was elicited among them by watching 2 video clips, and an 8-channel bio-feedback instrument was used to record their autonomic nervous responses and the average recovery time by down-regulating emotion strategy. Results (1) When the cognitive-avoidance was employed, the blood volume pulse (BVP) in the low mental quality group ( \[5.47±6.33\] mmHg, 1 mmHg=0.133 kPa) was significantly higher than those in the moderate and high mental quality groups (\[1.26±2.54; 0.94±3.10\] mmHg), but the standard deviation of all normal intervals(SDNN) in the low mental quality group ( \[3.31±17.69 \] ms) was significantly lower than that in the high mental quality group ( \[52.23±47.30\] ms). (2)In the servicemen with high mental quality the recovery time of BVP (26.00±43.84) s\] was significantly higher by simply watching than those by expression-suppression (\[23.50±34.96\] s) and the cognitive-avoidance ( \[22.00±36.15 \]s). Meanwhile, the recovery time of skin conductance (SC) in high mental quality group (\[106.50±20.28\]s) was significantly higher than that in the low mental quality group( \[103.00±37.73\]s).(3)When the cognitive-avoidance strategy was used, the recovery time of SC was significantly longer in the high mental quality group (\[68.50±49.39\] s) than that in moderate ( \[106.50±24.95\]s ) and low mental quality groups ( \[118.00±4.22\]s). (4)There was no significant difference in autonomic nervous responses between the different mental quality groups when down-regulating modulation was used to reduce the fear emotion. Conclusion Cognitive-avoidance strategy is more beneficial for the servicemen with high mental quality receiving down-regulating modulation of the fear emotion. The ability to regulate the sympathetic nerve and parasympathetic nerve is stronger in servicemen with high mental quality level than those with moderate and low mental qualities. |
