为检验同伴侵害影响儿童孤独感的中介变量,采用同伴提名、儿童自我知觉量表、儿童孤独感量表和班级戏剧问卷对武汉市某小学3-6年级445名儿童进行了调查。结果发现:同伴接纳和整体自尊是同伴侵害与孤独感间的两个中介变量。 在考察单一变量的中介作用时,同伴接纳在儿童的同伴侵害与其孤独感间起完全中介作用,而整体自尊在儿童的同伴侵害与其孤独感间起部分中介作用;当同时考察同伴接纳与整体自尊的中介作用时,同伴接纳与整体自尊在同伴侵害与孤独感间起完全中介作用,而且,由于同伴接纳对整体自尊的正向预测作用,同伴侵害对整体自尊的预测关系不显著。 相似文献

采用改进的flanker范式,探讨了刻板印象激活效应对社会分类的影响,并考察了匹配刺激出现概率对刻板印象激活效应影响社会分类的调节作用。实验一发现,性别刻板印象激活后,按性别分类时,匹配刺激中和不匹配刺激中面孔分类反应时之间的差异是显著的,但按年龄分类时,二者间的差异不显著。实验二表明,匹配刺激出现概率为80%时和50%时,匹配刺激中和不匹配刺激中面孔分类反应时之间的差异是显著的;但当匹配刺激出现概率为20%时,二者间的差异不显著。结果表明,刻板印象激活效应对与该刻板印象对应的社会分类有显著的影响,对与该刻板印象无关社会分类不会产生影响。刻板印象激活效应对社会分类的影响受匹配刺激出现概率的调节。 相似文献

Previous research showed that in the individualistic culture, adults endorse the personal more than the general belief in a just world (PBJW vs. GBJW). Comparatively little is known about the prevalence character and adaptive functions of GBJW, especially in the collectivistic culture. We conducted three surveys among the Chinese adults and adolescents. We found that (1) Chinese adults and adolescents endorsed more GBJW than PBJW; (2) Adult survivors with high exposure to post‐earthquake trauma and adolescents in the poverty‐stricken area maintained high GBJW, with relatively lower PBJW. (3) GBJW predicted the psychological resilience in all the three samples independent of PBJW. The results imply that in contrast to populations from the individualistic culture, people from the collectivistic culture endorse a robust GBJW, which allows them to resiliently confront harsh realities.

There is a growing consensus that the mental lexicon contains both abstract and word-specific acoustic information. To investigate their relative importance for word recognition, we tested to what extent perceptual learning is word specific or generalizable to other words. In an exposure phase, participants were divided into two groups; each group was semantically biased to interpret an ambiguous Mandarin tone contour as either tone1 or tone2. In a subsequent test phase, the perception of ambiguous contours was dependent on the exposure phase: Participants who heard ambiguous contours as tone1 during exposure were more likely to perceive ambiguous contours as tone1 than participants who heard ambiguous contours as tone2 during exposure. This learning effect was only slightly larger for previously encountered than for not previously encountered words. The results speak for an architecture with prelexical analysis of phonological categories to achieve both lexical access and episodic storage of exemplars. 相似文献

The relationship between ecstasy use and suicidal behavior among adolescents in the United States was examined. Data from the adolescent subsample (ages 12-17, N = 19,301) of the 2000 National Household Survey on Drug Abuse were used in the analyses. Information on adolescent substance use, suicidal behaviors, and related sociodemographic, family, and individual factors was obtained in the survey. The rate of past year suicide attempt among adolescents with lifetime ecstasy use was almost double that of adolescents who had used other drugs only, and nine times that of adolescents with no history of illicit drug use. In multinomial logistic regression analyses controlling for related factors, the effect of ecstasy use remained significant. Adolescent ecstasy users may require enhanced suicide prevention and intervention efforts. 相似文献
