俞国良  金东贤 《心理科学》2003,26(4):608-611
采用CBCL量表、自编的婚姻关系和亲子关系问卷调查了6所城市幼儿园的457名3~6岁幼儿,结果发现:(1)本研究中3~6岁幼儿心理行为问题的检出率为15.10%;(2)3-6岁幼儿的心理行为问题主要表现为交往不良、攻击性等外部行为问题;(3)没有心理行为问题的幼儿家庭其婚姻关系在性格相容、问题解决和性生活方面显著优于有心理行为问题的幼儿家庭,但在经济条件方面则相反;(4)婚姻关系和亲子关系则呈显著的正相关,并共同影响幼儿的心理行为问题。  相似文献

学习支持对儿童在多媒体语境中学习英语词汇的影响   总被引:4,自引:0,他引:4  
孙燕青  董奇 《心理科学》2003,26(5):800-803
该研究旨在考察中文翻译与主题提示两种学习支持对儿童在多媒体语境中学习英语词汇的作用,为此设计了三种学习条件:无支持条件、中文翻译条件和中文翻译 主题提示条件。对学龄初期儿童在上述三种学习条件下学习英语词汇的过程和结果进行的考察和分析表明:儿童在无支持条件下的学习效果较差;中文翻译可以明显促进儿童对语句的理解,但无法提高儿童对目标词的掌握;中文翻译 主题提示条件下儿童对单词语义的掌握最好,他们表现出了较多的跟读行为,并更倾向于认为学习任务较为容易。  相似文献

中学生知识获得过程是从情景记忆向语义记忆转化的过程   总被引:2,自引:0,他引:2  
隋洁  吴艳红  王金凤  朱滢 《心理科学》2003,26(5):784-789
本研究探讨中学生的知识掌握过程。针对2001—2002年度上学期教学内容,对初中二年级学生的四门课程分别进行两次测验。对于每道选择题,学生首先选择正确答案,然后指出记忆的意识状态:记住的、知道的、猜测的。结果发现,学生记忆意识类型的转变(由记住向知道)取决于课程类型、保持时间和学生等级。对于不同课程,学生占优势的意识类型不同,自然学科知道的反应占优势,社会学科记住的反应占优势;优等生知道的反应多于其他学生;随着学习时间的延长,中学生的意识类型发生了由记住向知道的转变,这表明知识掌握过程中,中学生的知识表征发生了由情景记忆向语义记忆的转变。  相似文献

中学生学业成就归因与学习动力的相关研究   总被引:2,自引:0,他引:2  
用自编问卷对913名中学生学业成就归因和学习动力状况进行了调查,发现: (1)整体上看中学生较多使用内在原因和可控原因解释自己的学习成绩; (2)不同性别和不同年级学生有不同的归因倾向; (3)归因倾向与学习动力有明显联系,使用因子分析法得到“自挫因子”对学习动力有很大的消极影响。本文还就如何进行归因训练进行了讨论。  相似文献

The key aim of the present research was to study the “functionality” of two global variables in the Olweus Bully/Victim Questionnaire and to examine the appropriateness of different cutoff points of these variables for prevalence estimation. Several empirical and conceptual analyses strongly attested to the functionality of the two selected variables in terms of construct validity and selected measurement properties. Similarly, a number of analyses indicated that (having been bullied/having bullied other students) “2 or 3 times a month” was a reasonable and useful lower‐bound cutoff point. With this cutoff point, “involved” students, victims, and bullies differed very markedly and in clearly different ways from “non‐involved” students in conceptually related variables. Prevalence estimates derived in this way can be conveniently obtained, have a reasonably well‐defined meaning, can be easily understood by users, and can be reproduced unambiguously by different researchers/administrators and at different times. An important background for the article is the fact that several common methods, including peer nominations, are not well suited for prevalence estimation. Prevalence data for victims, bullies, and bully‐victims are also presented. All data were derived from the New Bergen Project Against Bullying, comprising a sample of 5,171 students from 37 schools in the town community of Bergen, Norway. At the time of the data collection, the spring of 1997, the 2,544 girls and 2,627 boys were in grades 5 through 9, with modal ages of 11 through 15 years. Aggr.

The effects of testosterone propionate, an anabolic‐androgenic steroid, on the behavior displayed during a social encounter by gonadally intact male mice were investigated. Animals were distributed into three groups according to their attack latency in a pre‐screening test (high‐, moderate‐, and low‐ attacking mice) and each group received weekly injections of 60 or 120 mg/kg of testosterone or sesame oil for 10 weeks. Behavioral tests were then carried out. Afterwards, organs were weighed and blood samples collected in order to obtain hormonal data. Treatment had a differential impact on attack in the three groups of animals. Only the high‐attacking testosterone‐treated mice showed lower total duration of attack than their controls. Those that received 60 mg/kg spent more time exhibiting exploratory behaviors. As an index of the anabolic activity of the drug, all testosterone‐treated mice had heavier kidneys and, as an index of the androgenic activity of testosterone propionate, they had heavier seminal vesicles, lighter testes, and showed higher testosterone levels in a dose‐dependent way than their controls. Hence, the effect of treatment on peripheral physiological parameters was similar in all three groups whereas behavioral effects differed depending on basal aggressiveness, considered a characteristic of coping style.

Media commentators have suggested that recent school shootings were precipitated by social rejection, but no empirical research has examined this claim. Case studies were conducted of 15 school shootings between 1995 and 2001 to examine the possible role of social rejection in school violence. Acute or chronic rejection—in the form of ostracism, bullying, and/or romantic rejection—was present in all but two of the incidents. In addition, the shooters tended to be characterized by one or more of three other risk factors—an interest in firearms or bombs, a fascination with death or Satanism, or psychological problems involving depression, impulse control, or sadistic tendencies. Implications for understanding and preventing school violence are discussed. Aggr. Behav. 29:202–214, 2003. © 2003 Wiley‐Liss, Inc.  相似文献

This paper examines the occurrence of framing effects when more thought is given to problems. In Study 1, participants were presented with one of two frames of several decision problems. Participants' Need for Cognition (NC) scores were obtained, and half the participants were asked to justify their choices. Substantial framing effects were observed, but the amount of thought purportedly given to a problem, whether manipulated by justification elicitation or measured by NC scores, did not reduce the incidence of framing effects. In Study 2, participants responded to both frames of problems in a within‐subjects design. Again, NC scores were unrelated to responses on the first frame encountered. However, high‐NC, compared to low‐NC, participants were more consistent across frames of a problem. More thought, as indexed here, does not reduce the proclivity to be framed, but does promote adherence to normative principles when the applicability of those principles is detectable.
