目的 考察肢体加压疼痛对疼痛相关字词的注意偏向的影响与性别差异.方法 于被试者左臂肘横纹上方1～2 cm处捆绑止血带,采用dot-probe任务对32名健康大学生在有或无加压条件下进行五类疼痛相关字词(情感性疼痛词、感觉性疼痛词、社会威胁性词、积极词与中性词)的注意研究,加压压力为200 mm Hg.记录被试者认知反应的反应时与错误率,同时记录被试者的疼痛强度与疼痛不适度.结果 (1)与无加压相比,疼痛条件下女性反应时显著缩短(F(1,4)=19.157,P＜0.01),表现为对情感性疼痛词及社会威胁性词的反应速度加快[加压疼痛时两者反应时分别为[(464±79)ms,(465±72)ms]；无加压时分别为[(507±78)ms,(504±89) ms].(2)无加压实验中男性的反应时[(456±59)ms]短于女性的反应时[(504±79)ms](F(1.4)=18.779,P＜0.01),而加压疼痛实验中男女反应时差异消失[分别为(454±63)ms,(474 ±77)ms].结论 实验性中重度疼痛会引起女性被试者对字词的反应速度加快,表现出对情感性疼痛词和社会威胁性字词的注意偏向.
目的 攷察肢體加壓疼痛對疼痛相關字詞的註意偏嚮的影響與性彆差異.方法 于被試者左臂肘橫紋上方1～2 cm處捆綁止血帶,採用dot-probe任務對32名健康大學生在有或無加壓條件下進行五類疼痛相關字詞(情感性疼痛詞、感覺性疼痛詞、社會威脅性詞、積極詞與中性詞)的註意研究,加壓壓力為200 mm Hg.記錄被試者認知反應的反應時與錯誤率,同時記錄被試者的疼痛彊度與疼痛不適度.結果 (1)與無加壓相比,疼痛條件下女性反應時顯著縮短(F(1,4)=19.157,P＜0.01),錶現為對情感性疼痛詞及社會威脅性詞的反應速度加快[加壓疼痛時兩者反應時分彆為[(464±79)ms,(465±72)ms]；無加壓時分彆為[(507±78)ms,(504±89) ms].(2)無加壓實驗中男性的反應時[(456±59)ms]短于女性的反應時[(504±79)ms](F(1.4)=18.779,P＜0.01),而加壓疼痛實驗中男女反應時差異消失[分彆為(454±63)ms,(474 ±77)ms].結論 實驗性中重度疼痛會引起女性被試者對字詞的反應速度加快,錶現齣對情感性疼痛詞和社會威脅性字詞的註意偏嚮.

Objective To investigate the effect and gender differences of experimental moderate pain on attentional bias towards pain-related words.Methods With the tourniquet around the left upper limb,32 healthy college students were asked to perform two dot-probe tasks including five kinds of pain-related words,one task with the tourniquet deflating and the other task with the tourniquet inflating to 200 mm Hg pressure.The reaction time (RT) and the error rate of recognition task were recorded.The pain intensity and distress were recorded too.Results ( 1 ) Compared with no pain condition ( RT of affective and social-threat words were (507 ± 78 ) ms,(504 ±89 )ms respectively),the react time was shorter in female in the condition of tourniquet pain,particularly for affective and social-threat words (the RT were (464 ± 79 )ms,(465 ± 72 )ms respectively,F ( 1,4) =19.157,P ＜0.01 ),but not in male.( 2 ) In condition of no pain,the reaction time of male ( (456 ± 59) ms ) was shorter than that of female (504 ± 79ms).However,in the condition of pain,the significant main effect was not found.Conclusion The reacting time of female was shorter in condition of moderate tourniquet pain,which imply that female showed significant attentional bias towards affective and social-threat words.
