许多监管任务要求操作者记住随机发生的、必须在规定时刻内给予一定反应的许多刺激。这样在刺激—反应之间就出现了复杂的交迭过程。本实验模拟这类刺激—反应情境,将简单的任务信息随机呈现在IBM PC/XT计算机屏幕上,要求被试在指定时间给出适当的反应。实验Ⅰ的结果表明,任务呈现间隔时间影响交迭记忆的业绩,交迭记忆业绩随任务间隔时间的延长而提高。进而说明时间繁忙是心理负荷的时间因素。 相似文献

不同年级青少年的友伴网络结构 总被引:7,自引:2,他引:5
选择小六、初二和高一学生共1040名作被试,采用十项友伴提名法,要求被试至多提名10个友伴,通过网络分析,从友伴提名数、友伴选择的双向性两个方面探讨不同年级学生友伴网络结构,结果显示,青少年平均拥有6~7个友伴,在这些友伴关系中,单向选择占明显的优势。性别、年级和学习成绩之间的交互作用以及父母受教育水平和家庭结构之间的交互作用(包括两两之间的交互作用)除个别外,均不明显;性别、年级和学习成绩的主效应较明显,而父母受教育水平和家庭结构的主效应却不明显。 相似文献

三国四城市小学儿童数学成绩的比较研究——跨文化研究之一 总被引:2,自引:0,他引:2
本研究是中国科学院心理研究所和美国密西根大学的协作项目。数学团体测验是整体研究项目的一部分。这一研究的目的是比较在不同文化背景下北京(中)、芝加哥(美)、仙台(日)和台北(中)小学儿童的数学成绩。其结果表明:亚洲学生的成绩显著高于美国儿童的成绩。我们试将美国教材同其它国家的教材进行比较,已初步看出,教材讲授的时间可能是影响中国儿童成绩的重要因素之一。学生的学习态度可能是影响儿童成绩的另一因素。其它方面如家庭条件、母亲的观念、教师的教学风格以及课堂的组织形式都可能影响儿童的学习成绩。我们对此将陆续提出报告。 相似文献

With the growth of research collaborations, the average number of authors per article and the phenomenon of equally important authorships have increased. The essence of the phenomenon of equally important authorships is the approximately equal importance of authors, both because of the difficulties in comparing authors’ contributions to a paper and some actual research evaluation practices, which (approximately) give full paper credit only to the most important authors. A mechanism for indicating that various authors contributed equally is required to maintain and strengthen collaboration. However, the phenomenon of multiple important authors can cause unfair comparisons among the research contributions and abilities of authors of different papers. This loophole may be exploited. Normalizing the credit assigned to a given paper’s authors is an easy way to solve this ethical dilemma. This approach enables fair comparisons of the contributions by the authors of different articles and suppresses unethical behaviour in author listings. Bibliometric researchers have proposed mature methods of normalized paper credit assignment that would be easy to use given the current level of computer adoption. 相似文献

Young children's self‐benefiting lies and their relation to executive functioning and theory of mind

It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self‐benefiting lies emerge, and what cognitive factors affect the emergence of self‐benefiting lies. To bridge this gap in the literature, we situated children between 2 and 4 years of age in a zero‐sum game where children must lie to their opponent if they wanted to win a desirable reward. We found that the majority of young children did not lie even when they experienced personal losses repeatedly. However, some children spontaneously lied during the game; as the game progressed, more children lied. Further, we found that children's theory of mind understanding and executive functioning in terms of a combination of inhibitory control and cognitive flexibility had significant positive and unique correlations with how frequently children lied for personal gain. The present results taken together with the existing findings regarding children's lies for self‐protection and politeness purposes suggest that the act of lying begins early in life. Further, its emergence and development are influenced by children's specific cognitive abilities in the domains of theory of mind understanding and executive functioning.
Highlights
- The study investigated whether very young children will spontaneously lie for personal gain.
- This study used a zero‐sum game to elicit children's self‐benefiting lies. Results showed the majority of young children did not lie, and it is related to children's theory of mind understanding and executive functioning.
- The act of lying begins early in life, and its emergence and development are influenced by children's specific cognitive abilities in the domains of theory of mind understanding and executive functioning.

Because of the central role of working memory capacity in cognition, many studies have used short measures of working memory capacity to examine its relationship to other domains. Here, we measured the reliability and stability of visual working memory capacity, measured using a single-probe change detection task. In Experiment 1, the participants (N = 135) completed a large number of trials of a change detection task (540 in total, 180 each of set sizes 4, 6, and 8). With large numbers of both trials and participants, reliability estimates were high (α > .9). We then used an iterative down-sampling procedure to create a look-up table for expected reliability in experiments with small sample sizes. In Experiment 2, the participants (N = 79) completed 31 sessions of single-probe change detection. The first 30 sessions took place over 30 consecutive days, and the last session took place 30 days later. This unprecedented number of sessions allowed us to examine the effects of practice on stability and internal reliability. Even after much practice, individual differences were stable over time (average between-session r = .76). 相似文献
