1、情緒效價(jià)強(qiáng)度對(duì)抑郁癥狀個(gè)體認(rèn)知控制的影響李嘉雯,馮正直,廖成菊,蔣娟,王曉霞（400038重慶,第三軍醫(yī)大學(xué)護(hù)理學(xué)院心理學(xué)教研室）[摘要]目的：探討情緒刺激效價(jià)強(qiáng)度對(duì)抑郁癥狀個(gè)體認(rèn)知控制的影響特點(diǎn)。方法：以貝克抑郁量表和Zung編制的抑郁自評(píng)量表為工具，選取重慶某大學(xué)本科生，發(fā)放問(wèn)卷600份，回收有效問(wèn)卷585份。在重慶某所大學(xué)對(duì)520人進(jìn)行前期問(wèn)卷篩查利用貝克抑郁量表（Beckdepressioninvertory，BDI）和自評(píng)抑郁量表（self-ratingdepressionscales，SDS）進(jìn)行篩選，得到抑郁癥狀被試23名和健康被試23名篩選出健
2、康被試與抑郁癥狀被試各23名，利用經(jīng)典的雙選擇情緒Oddball實(shí)驗(yàn)范式，比較不同情緒刺激效價(jià)強(qiáng)度對(duì)兩組被試的認(rèn)知控制的正確率和反應(yīng)時(shí)的差異。結(jié)果：①?gòu)恼_率分析來(lái)看，健康組(F=11.221，P<0.01)與抑郁癥狀組(F=12.310，P<0.01)分別在情緒效價(jià)強(qiáng)度變化上有顯著差異，兩組在高負(fù)性、中性和低正性中目標(biāo)刺激均高于高正性和低負(fù)性，高正性和低負(fù)性沒(méi)有差異。②從反應(yīng)時(shí)分析來(lái)看，健康組(F=2.903，P<0.05)與抑郁癥狀組(F=3.256，P<0.05)分別在情緒效價(jià)強(qiáng)度（愉悅度）變化上有顯著差異；但是對(duì)于健康組，在高負(fù)性、中性、低正性和高正性
3、中目標(biāo)刺激反應(yīng)時(shí)長(zhǎng)于低負(fù)性；對(duì)于抑郁癥狀組，在高負(fù)性和低正性中目標(biāo)刺激反應(yīng)時(shí)高于中性和高正性。結(jié)論:情緒效價(jià)強(qiáng)度對(duì)抑郁癥狀個(gè)體的認(rèn)知控制影響存在差異，且影響程度隨著情緒強(qiáng)度變化而變化。隨著負(fù)性情緒強(qiáng)度的增加，抑郁癥狀個(gè)體認(rèn)知控制反應(yīng)延遲；隨著正性情緒強(qiáng)度的增加，抑郁癥狀個(gè)體認(rèn)知控制反應(yīng)提前。[關(guān)鍵詞]情緒；效價(jià)；認(rèn)知控制；抑郁癥狀；影響TheeffectofValenceStrengthforDifferentEmotionalStimulionCognitiveControlinDepressiveSymptomIndividualsLiJianwen,Fe
