【摘要】 社会比较是指人们经常会以自己为参照系和别人进行比较,社会比较的方向分为上行比较和下行比较,上行比较是指和比自己好的人进行比较从而产生负面情绪,而下行比较是指和比自己差的人进行比较从而产生正面情绪。有研究表明身体意向与上行比较引起的负面情绪相关。第一人称效应是指人们对自身有关的信息非常敏感,反应会比其他信息要快,而与之对立的现象是第三人称效应。大量研究说明有关身体意向的媒体信息与第三人称效应有关,但很少有研究与身体意向有关的图片会引起第一人称效应还是第三人称效应。本研究采用ERPs技术对社会比较和第一人称效应与身体意向之间的关系进行分析,结果显示:1)P2波的波峰上行比较要比下行比较要大;2)N300波的平均波幅上行比较比下行比较要大;3)LPC波的平均波幅第一人称比第三人称的要大;4)LPC波370-560s的平均波幅上行比较比下行比较要大,560-680s的平均波幅没有显著性差异,680-1000s的平均波幅上行比较要比下行比较小。由此可得出结论,身体意向与社会比较上行比较产生的负面情绪相关,第一人称效应在身体意向相关的图片呈现时显著。更多还原

【Abstract】 Social comparison is the process through which people come to know themselves by evaluating their own attitudes, abilities, outcomes, and beliefs in comparison with others. There are two directions of social comparison including up-ward comparison and down-ward comparison. The up-ward comparison is to compare with superior others and elicits negative emotion, while the own-ward comparison is to compare with inferior others and elicits positive emotion. Researches suggest that the negative feeling elicited by up-ward comparison is related with body image. And the First person effect makes people more sensitive to self-relevant information and respond more quickly, so does the Third person effect effects on other-relevant information. Researches show a significant relation between media which is related with body image and the Third person effect, but non research suggests that the body-image-relevant pictures elicit the First person effect or the Third person effect. This research is an ERPs study about the relationship between social comparison, First person effect and body image. The results show: 1) the peak amplitude of up-ward comparison is larger than the peak amplitude elicited by down-ward comparison; 2) the average amplitude of up-ward is larger than those of down-ward comparison on C3; 3) as to LPC, average amplitude of self-relevant is larger than those of other-relevant; 4) as to social comparison in LPC, in 370-560 s time window the average amplitude of up-ward is larger than those of down-ward comparison, in 560-680 s time window there is no significant effect, in 680-1000 s time window the average amplitude of down-ward is larger than those of up-ward comparison. The data suggest that body image is related with the negative feeling elicited by up-ward social comparison, and body image-relevant pictures elicit significant First person effect.更多还原
