不同焦虑程度青少年考试焦虑的HRV特征论文随机验证编号:BT5271021521070IV摘要研究目的:本文旨在对即将参加体育高考的学生在考试前不同心理应激条件下进行HRV监控以及相关心理量表的自评,探讨心率变异性指标评价学生考试焦虑的可行性以及不同程度特质焦虑、不同程度状态焦虑、不同考试成绩学生的HRV特征。研究方法:利用RS800型号polar表测试30名体育高考生考试前后三个阶段下的HRV时域、频域指标,同时采用《状态-特质焦虑问卷》将考生分为不同程度焦虑组别,利用重复测量方差分析与事后检验,分析不同考试阶段考生的HRV变化规律以及不同考生的HRV特征。研究结果:1所有HRV指标在考试前后三个阶段均出现显著性差异,重复测量方差分析结果显示考试前一天与考试前三天、考试后一天均具有显著性差异(P0.05);2特质焦虑程度不同的考生,HRV指标LF/HF有显著性差异(F=8.659,P=0.009)其余指标在组间均无显著性差异,指标HR接近显著水平(P=0.69);3状态焦虑程度不同的考生,除指标PNN50外,其余HRV指标均出现显著性差异,其中高焦虑组HR、LF、LF/HF显著高于低焦虑组,其余指标则相反(P0.05),其中指标HR、LF/HF差异非常显著(P0.01);4单因素方差分析结果表明除指标LF外,其余指标均在发挥程度不同的考生中出现显著性差异,事后检验显示超常发挥的考生指标HR、LF/HF显著低于发挥失常的考生,指标SDNN、RMSSD则显著高于后者,指标PNN50、HF显著高于发挥失常组与正常发挥组,发挥失常组的指标LF/HF则显著高于其他两组(P0.05)。研究结论:1考试焦虑会引起学生HRV指标的差异,HRV指标评价考试焦虑具有较高的敏感性。2利用HRV指标对于不同特质焦虑个体在考试环境下的区分度较低,特质焦虑程度的差异较难影响考生考试前自主神经系统的差异。3用HRV指标区分不同状态焦虑个体在考试环境下的可行性较高,说明状态焦虑明显造成考生考试前的自主神经系统的变化。4考试发挥水平不同的考生表现出不同的HRV特征,说明将HRV指标应用不同焦虑程度青少年考试焦虑的HRV特征论文随机验证编号:BT5271021521070V于评价考前及赛前的心理状态有一定的价值。关键词:考试焦虑;心率变异性;特质焦虑;状态焦虑不同焦虑程度青少年考试焦虑的HRV特征论文随机验证编号:BT5271021521070VIABSTRACTPurpose:ThepurposeofthisstudywastodiscussthecharacteroftheHRVonthedifferentstateanxietyandtraitanxiety,sotohelpcounselorandclinicalpsychologiststoestablishpreventionandinterventionmeasures.Methods:First,30highschoolstudentswhowouldtakepartinthecollegeentranceexamwereasthesamples,usingState-TraitAnxietyInventory(STAI)。Second,RS800POLARwereusedtoexploretheeffectofmentalarithmeticstressonheartrate,heartratevariability(HRV)amongstudentswithdifferentanxietyduringtheexam.Results:1AlltheHRVindexeshassignificantdifferenceduringthedifferentstageofthetest.2TheresultofrepeatedmeasurementssuggestssignificantdifferencebetweensomeoftheHRVlinearanalytictarget(HR、LF/HF)ofdifferenttraitanxiety.3TheresultofrepeatedmeasurementssuggestssignificantdifferenceamongalltheHRVlinearanalytictargetofdifferentstateanxiety.4AlltheHRVindexeshassignificantdifferenceofallthestudentsduringthedifferenttimeoftheexam.Conclusions:1theanalytictargetisvaluableintheclassificationofthetestanxiety,testanxietycauseHR、LF、LF/HFincreasedandSDNN、RMSSD、PNN50、HFdecreasedsignificantly.2IndexesLF/HFhadsignificantdifferenceamongdifferentindividualswithdifferenttraitanxiety,therewereno.significantdifferenceintheremainingindicators.3AlltheHRVindexesexceptPNN50hadsignificantdifferenceamongdifferentindividualswithdifferentstateanxiety.不同焦虑程度青少年考试焦虑的HRV特征论文随机验证编号:BT5271021521070VII4ThecharacteroftheHRVhavecorrelationwithperformanceresultsandtrainingandmotivation,theindexesofPNN50、HF、LF/HFcandistinguishdifferentexaminationcandidates.KeysWords:testanxiety;HRV;traitanxiety;stateanxiety不同焦虑程度青少年考试焦虑的HRV特征论文随机验证编号:BT5271021521070-1-目录1前言....................................................41.1问题提出....................................................41.2研究目的....................................................41.3研究意义....................................................51.3.1理论意义........................................................51.3.2实践意义........................................................52文献综述................................................62.1心理应激....................................................62.1.1心理应激定义....................................................62.1.2应激源定义及分类................................................62.1.3心算应激源......................................................72.1.4演讲应激源......................................................82.1.5Stroop彩色字测试.................................................82.1.6时间压力........................................................82.1.7应激的心理反应..................................................92.2焦虑........................................................92.2.1焦虑的定义......................................................92.2.2特质焦虑与状态焦虑..............................................92.2.3考试焦虑.......................................................102.2.4焦虑的测量.....................................................112.2.5情绪体验的测量.................................................112.2.6行为表现的测量.................................................112.2.7生理反应的测量.................................................122.3心率变异性(HRV)..........................................122.3.1心率变异性定义及生理意义........................................122.3.2心率变异性分析方法.............................................13不同焦虑程度青少年考试焦虑的HRV特征论文随机验证编号:BT5271021521070-2-2.3.3HRV在临床研究的应用...........................................142.3.4HRV在生理心理学的应用.........................................142.4国内外相关研究.............................................152.4.1有关特质焦虑与状态焦虑的实验研究...............................152.4.2有关考试焦虑的相关研究.........................................162.5研究局限...................................................173研究对象与方法........................................173.1实验对象...................................................183.2实验方法...................................................183.2.1问卷调查.......................................................183.2.2HRV测试.......................................................193.2.3测试流程.....................................
