Task-irrelevant spatial information, conveyed by stimulus location, location word, or arrow direction, can influence the response to task-relevant attributes, generating the location-, word-, and arrow-based Simon effects. We examined whether different mechanisms are involved in the generation of these Simon effects by fitting a mathematical ex-Gaussian function to empirical response time (RT) distributions. Specifically, we tested whether which ex-Gaussian parameters (μ, σ, and τ) show Simon effects and whether the location-, word, and arrow-based effects are on different parameters. Results show that the location-based Simon effect occurred on mean RT and μ but not on τ, and a reverse Simon effect occurred on σ. In contrast, a positive word-based Simon effect was obtained on all these measures (including σ), and a positive arrow-based Simon effect was evident on mean RT, σ, and τ but not μ. The arrow-based Simon effect was not different from the word-based Simon effect on τ or σ but was on μ and mean RT. These distinct results on mean RT and ex-Gaussian parameters provide evidence that spatial information conveyed by the various location modes are different in the time-course of activation. 相似文献

Research on the antecedents and underlying mechanisms of the formation of adolescent social trust is scant. Family and school are two major environments in which adolescents become socialized. The current study examined the effect of parental rearing behaviors (rejection, emotional warmth and overprotection) on adolescent social trust, exploring the mediating role of adolescent self-esteem and the multilevel moderated role of the Level 2 variable class justice climate. The sample included 612 (12–16 years old) middle school students in China. Participants completed the s-EMBU, the Rosenberg Self-esteem Scale, Rosenberg’s Faith in People Scale and the perceptions of class justice scale, along with other control variables. The results suggested that parental rearing behaviors significantly predicted adolescent social trust, regardless of adolescent gender or age. Additional mediation analysis suggested that parental rearing behaviors had both direct effects on adolescent social trust and indirect effects through adolescent self-esteem. Further multilevel structural equation modeling indicated that class justice climate moderated the effect of parental rejection on adolescent self-esteem. The findings suggest that family and school practice jointly shape adolescents’ social trust. How parents treat their children has a huge influence on the degree to which their children trust other people. In addition, perceived class justice could buffer the harmfulness of negative parental rearing behaviors. 相似文献

The correlation between age and empathy is not clear, with prior findings yielding mixed and inconsistent results. Here, we distinguished between two aspects of empathy and respectively investigated the effects of age on the affective and cognitive facets of empathy using a self-report measure (interpersonal reactivity index, IRI) and performance-based tasks (viewing films). The results showed that older adults manifested age-related deficits in both trait and state cognitive empathy, with the latter being positively associated with memory. Otherwise, the overall affective empathy increased in the elderly, but the age-related differences in affective empathy may be qualified by the valence of the film clips. Specifically, older participants showed more empathic concern (EC) and less personal distress (PD) to other people’s emotions than the younger participants for the distress film. Interestingly, for the amusing film, older participants demonstrated more EC and PD. Overall, the two aspects of empathy have different development trajectories. 相似文献

Individual self-construal (independent vs. interdependent) could be temporarily modulated by the priming effect. Our previous studies have found that when Chinese participants gambled for mother and for self, outcome feedback evoked comparable neural responses between two conditions. However, it remains unclear if the response to rewards for mother and for self would differ after independence self-construal priming. In this study, we manipulated participants’ self-construal (independent vs. interdependent) before a simple gambling task. The event-related potential (ERP) results reveal that when an interdependent self-construal was primed, the participants exhibited a comparable feedback-related negativity (FRN) elicited by outcome feedback for self and for mother. In contrast, independent self-construal priming resulted in a greater FRN elicited by outcome feedback for self than for mother. Meanwhile, the P3 component was insensitive to self-construal manipulation. These findings indicate the modulation effect of self-construal priming on the response to rewards for others. 相似文献

本研究探讨被动与主动语码切换过程中的语码切换代价及抑制控制的作用。该实验以阿拉伯数字为实验材料,随机选取高校汉-英双语大学生为被试,要求被试完成数字命名任务。结果表明,被动语码切换过程存在语码切换代价且代价对称,这一现象既可以用特定语言选择假说解释,也可以用抑制控制模型来解释,但未能直接支持抑制控制真正参与被动语码切换,有待进一步研究; 主动语码切换过程中,目标语言为汉语时存在语码切换代价,而目标语言为英语时不存在语码切换代价,可能是抑制控制机制与词汇选择策略共同参与的结果。 相似文献

This study investigated the development of moral judgments of blue lies, which occur when a speaker makes false statements to benefit a group of which he or she is a member. We investigated this issue in China, where there is substantial emphasis on the nature of children's associations with groups they belong to. Participants ranged in age from 9 to 17, and we asked them to evaluate lies that were told to benefit a team representing a speaker's class, school, or country. Judgments varied systematically as a function of age, with the 17‐year‐olds rating lying for any form of collective less negatively than did the younger age groups. In addition, across the age groups, children's affinity tended to shift from smaller groups to broader and more abstract collectives: 9‐ and 11‐year olds were least critical of blue lies told to benefit a speaker's class, 13‐year olds were least critical of blue lies told to benefit a speaker's school, and 17‐year olds were least critical of blue lies told to benefit a speaker's country.

一种新的等值准则及其适用范围的探讨 总被引:3,自引:0,他引:3
受假设检验方法的启发,该文引出了一种基于项目反应理论的新等值方法——平方根等值准则。它具有一些特点:定义式中答对、答错概率同时出现而不能互相替代;极易从0—1评分模式的版本转换到多级评分版本;它可以看成是Haebara等值准则的加权形式。以等值系数估计值的误差大小为衡量标准,以Wilcoxon符号秩检验为依据,大量的Monte Carlo模拟结果显示了一种有趣的现象,即等值方法的运用范围既与项目参数估计精度有关,又与等值系数A的范围有关,但与另一个等值系数B的范围无关。当项目参数估计精度较高或中等而A取值在0.9~1.3之间,新方法往往比Stocking_Lord方法和Haebara方法的估计误差小且有显著性差异,当项目参数估计精度较低时,而A从1.0~2.0时新方法都有优越性。 相似文献
