主要探讨不同延时间隔和线索类型对遗忘元认知判断的影响。采用传统的学习判断任务,让被试学习40对无意义配对词,并告知随后进行测试,当呈现第一个词时,被试能够回忆与之配对的后一个词。让被试预测当延迟不同时间(5分钟、1天和1周)进行测试时,他们能够记住(学习判断)或者遗忘(遗忘判断)后一词的可能性。最后,要求被试回忆所有词对。结果发现延时间隔对学习判断和遗忘判断有相似的影响;学习判断的等级和相对准确性均高于遗忘判断,说明人们对记住和遗忘的线索很敏感;相比于学习判断,人们监测自己遗忘能力的信心不足。研究结果表明人们能够利用延时间隔和线索类型来预测未来的测验成绩,对遗忘的监测能力低于对记住的监测。  相似文献

Using cross‐sectional data from rural‐to‐urban migrant adolescents in urban areas of Beijing, China, we examined the mediating effects of social support (i.e. teacher support and classmate support) in the relationship between perceived discrimination (PD) and antisocial behaviour (ASB) among Chinese migrant adolescents. Participants were 897 adolescents (459 boys and 438 girls, mean age = 13.34 years) from four migrant schools (68.8%) and four public schools (31.2%). Participants completed self‐report questionnaires concerning PD, ASB, teacher support and classmate support. Results indicated that Chinese migrant adolescents who perceived more discrimination were more likely to engage in ASB. Teacher support partially mediated the relationship between PD and ASB. Gender moderated this mediational relationship, such that teacher support exerted a mediating role among girls, but not boys. The findings suggest that reductions in teacher support may partially account for the effect of PD on ASB among Chinese migrant adolescents girls.  相似文献

Although treatment outcome in prize‐based contingency management has been shown to depend on reinforcement schedule, the optimal schedule is still unknown. Therefore, we conducted a retrospective analysis of data from a randomized clinical trial (Ghitza et al., 2007) to determine the effects of the probability of winning a prize (low vs. high) and the size of the prize won (small, large, or jumbo) on likelihood of abstinence until the next urine‐collection day for heroin and cocaine users (N = 116) in methadone maintenance. Higher probability of winning, but not the size of individual prizes, was associated with a greater percentage of cocaine‐negative, but not opiate‐negative, urines.  相似文献

Participants in China (n = 343) and the United States (n = 283) completed measures to assess the reliability and validity of the Fear of Intimacy Scale (Descutner & Thelen, 1991) with a Chinese population. Internal consistency was strong in both cultures, and the factor structure was also similar between cultures, with confirmatory factor analysis (CFA) identifying three-factor models in both samples. As evidence of convergent validity, the scale was positively correlated with depression and negatively correlated with social support and self-esteem. There were gender differences between cultures, but low levels of femininity were predictive of fear of intimacy in both cultures. The influence of individualism and collectivism varied, with high levels of individualism more predictive of a fear of intimacy in China than in the United States.  相似文献

以往关于内群偏私的研究大多采用社会认同理论(social identityt heory)做解释。近期,自我锚定(self-anchoring principle)原理被证实可用于解释内群偏私的原因。基于中国人及美国人在内群偏私的目的、方法上的不同,我们采用最小群体范式,验证这两种理论在中国大学生上的适用性。410名大学生(其中前测94名)在互联网上完成以认知能力评估为名的实验,实验控制反馈类型,要求参与者对自身、内群及外群在不同维度上评分。实验证明内群偏私存在;分化理论成立;采用演绎策略时,个体评价与内群评价的差异显著小于个体采用归纳策略时两者的差异,符合社会认同理论的假设。  相似文献

进展期胃癌术后生存质量影响因素探讨   总被引:4,自引:1,他引:3  
胃癌是我国发病率和病死率较高的恶性肿瘤,且住院病例90%以上为中晚期。因此预后不佳。近年来在进展期胃癌诊断和治疗方面有较大进展,尤其是人们对术后生存质量的重视。本文初步探讨了进展期胃癌术后生存质量的影响因素:如患者一般状况、手术方式、术后辅助放化疗和中医药治疗等。  相似文献

This paper uses a simulation approach to investigate how different attribute weighting techniques affect the quality of decisions based on multiattribute value models. The weighting methods considered include equal weighting of all attributes, two methods for using judgments about the rank ordering of weights, and a method for using judgments about the ratios of weights. The question addressed is: How well does each method perform when based on judgments of attribute weights that are unbiased but subject to random error? To address this question, we employ simulation methods. The simulation results indicate that ratio weights were either better than rank order weights (when error in the ratio weights was small or moderate) or tied with them (when error was large). Both ratio weights and rank order weights were substantially superior to the equal weights method in all cases studied. Our findings suggest that it will usually be worth the extra time and effort required to assess ratio weights. In cases where the extra time or effort required is too great, rank order weights will usually give a good approximation to the true weights. Comparisons of the two rank-order weighting methods favored the rank-order-centroid method over the rank-sum method. © 1998 John Wiley & Sons, Ltd.  相似文献

我们如何来理解和翻译笛卡尔的"mathesis universalis"?要知道这是笛卡尔整个哲学的一种方法论基础,它究竟是"普遍数学",还是"普遍科学"?它和笛卡尔的形而上学之间是否有某种关联?笛卡尔的形而上学又究竟意味着什么?我们通过梳理笛卡尔的"mathesis universalis"和形而上学概念就会发现,他的这个神秘的方法实际上包含着一种形而上学的预设,即其中的秩序思想蕴涵了一种形而上学的变革倾向,正是在这个意义上,我们认为更应该把"mathe- sis universalis"理解和翻译为"普遍科学",因为,如果我们仅仅把它理解和翻译为"普遍数学"的话,就削弱了笛卡尔哲学更加突出的形而上学变革意味。  相似文献
