目的 了解女大学生对国际情绪图片系统(International Affective Picture System,IAPS)中不同类型性图片(异性恋夫妇性图片、男性性图片、女性性图片)认知加工的神经机制差异.方法 应用事件相关电位(event-related potential,ERP)技术,比较18例正常女性观看中性图片和不同类型性内容图片时N2、P3及PSW波幅的差异.结果 异性恋夫妇性图片诱发,前额区N2[(0.99±1.69)μV]成分、顶区P3[(17.27±1.45)μV]成分最大,其次是男性性图片[(-0.02±1.83)μV,( 15.92±1.26) μV],再次是女性性图片[(-0.22±1.56)μV,(15.49±1.34)μV],且N2、P3波幅在异性恋夫妇性图片和女性性图片间差异具有统计学意义(均P＜0.05)；异性恋夫妇性图片[(15.22±1.98)μV]与女性性图片[(14.53±1.75)μV]诱发的PSW波幅差异无统计学意义,但均显著大于男性性图片[(10.93±2.60)μV](均P＜0.05).结论 高度暴露的异性恋夫妇性图片诱发女性最强的性唤起及消耗最多的注意资源,性唤起维持时间也最长.
目的 瞭解女大學生對國際情緒圖片繫統(International Affective Picture System,IAPS)中不同類型性圖片(異性戀伕婦性圖片、男性性圖片、女性性圖片)認知加工的神經機製差異.方法 應用事件相關電位(event-related potential,ERP)技術,比較18例正常女性觀看中性圖片和不同類型性內容圖片時N2、P3及PSW波幅的差異.結果 異性戀伕婦性圖片誘髮,前額區N2[(0.99±1.69)μV]成分、頂區P3[(17.27±1.45)μV]成分最大,其次是男性性圖片[(-0.02±1.83)μV,( 15.92±1.26) μV],再次是女性性圖片[(-0.22±1.56)μV,(15.49±1.34)μV],且N2、P3波幅在異性戀伕婦性圖片和女性性圖片間差異具有統計學意義(均P＜0.05)；異性戀伕婦性圖片[(15.22±1.98)μV]與女性性圖片[(14.53±1.75)μV]誘髮的PSW波幅差異無統計學意義,但均顯著大于男性性圖片[(10.93±2.60)μV](均P＜0.05).結論 高度暴露的異性戀伕婦性圖片誘髮女性最彊的性喚起及消耗最多的註意資源,性喚起維持時間也最長.

Objective To observe female university students' differences of cognitive mechanism in processing different types of sexual picture from International Affective Picture System (IAPS).Methods Using event related potential (ERP),the differences of the amplitudes of N2,P3 and PSW were examined induced by the neutral pictures and different types of erotic pictures.Results The amplitudes of N2 ( (0.99 ±1.69 ) μV) and P3 ( ( 17.27 ± 1.45 ) μV) elicited by heterosexual couple erotic pictures were highest,followed by the male erotic pictures( ( -0.02 ± 1.83 ) μV,( 15.92 ± 1.26 ) μV),and then were the female erotic pictures ( ( -0.22 ± 1.56)μV,( 15.49 ±1.34) μV).There was statistical significance in N2 and P3 between heterosexual couple erotic pictures and female erotic pictures ( P ＜0.05 ).There was no significant difference in PSW component between heterosexual couple erotic pictures( ( 15.22 ± 1.98 ) μV) and female erotic pictures ( ( 14.53 ± 1.75 ) μV ),but the PSW induced by male erotic pictures (( 10.93 ± 2.60 )μV) was significantly smaller than the other sexual pictures (P＜0.05).Conclusion The level of sexual arousal elicited by explicit heterosexual couple erotic pictures is highest and also the attention maintains longest.
