3~5岁儿童理解和使用空间表征的特点   总被引:2,自引:0,他引:2       下载免费PDF全文
以96名3~5儿童为被试,采用自编的儿童空间表征实验任务,在语言表征、模型表征和图画表征三种空间表征形式上,考察了儿童理解和使用空间表征的发展特点。结果表明:(1)总体上,3~5岁儿童理解空间表征的发展水平均显著高于使用空间表征的发展水平。(2)3~5岁儿童理解和使用空间表征的发展表现出显著的年龄效应。(3)从不同的空间表证形式来看,3岁儿童理解语言表征的能力与理解模型表征的能力之间差异显著,4岁儿童使用语言表征的能力与使用模型表征的能力之间的差异、使用语言表征的能力与使用图画表征的能力之间的差异、以及使用模型表征的能力与使用图画表征的能力之间的差异都显著,其余形式的空间表征理解之间的差异或空间表征使用之间的差异在各年龄段中均不显著。  相似文献

孤独感与手机成瘾均是当下生活中较为常见的现象, 诸多研究基于不同的理论视角探讨了两者间的内在联系, 但研究结果却存在很大分歧。为明确两者之间的整体关系, 以及产生分歧的原因, 对检索后获得的121项研究(124个效应值)使用随机效应模型进行了元分析。结果发现:孤独感与手机成瘾存在中等程度的正相关(r = 0.25, 95% CI = [0.23, 0.27]); 两者的相关性受被试年龄群体的调节, 成年人群体中的相关系数显著高于青少年群体, 但两者的相关性不受性别、孤独感和手机成瘾测量工具的影响。结果表明孤独感与手机成瘾关系密切, 支持了补偿性网络使用理论和自我调节缺陷模型。未来应加强纵向研究或实验研究进一步揭示孤独感与手机成瘾的作用方向。  相似文献

摘 要 为探讨网络使用对学业成就的影响及其作用机制,从自我效能感理论的角度使用问卷对425名小学生进行调查。结果表明:(1)网络使用完全通过学习效能感的中介作用正向预测学业成就;(2)学习效能感中介作用受到开放性的调节,即在开放性高的个体中,学习效能感在网络使用与学业成就之间的中介效应不显著;在开放性低的个体中,学习效能在网络使用与学业成就之间有显著的中介效应。研究结果揭示了网络使用对学业成就的影响与作用机制,对家长、教育工作者根据儿童的个人特质对网络使用进行适度引导有启示意义。  相似文献

以523名工读生为调查对象,考察工读生毒品使用特点,并在控制相关人口学变量后,探讨感觉寻求、压力性生活事件、结交不良同伴与工读生毒品使用的关系。结果显示:(1)工读生的毒品使用行为严重,34.2%的工读生曾使用过毒品,毒品使用呈现低龄化、以吸食新型毒品为主的趋势。(2)工读生的感觉寻求是毒品使用的风险因素。(3)压力性生活事件对感觉寻求与毒品使用之间的关系具有风险增强的调节效应。(4)这种调节效应以结交不良同伴为中介变量。因此,感觉寻求对工读生毒品使用的影响是有中介的调节效应。研究结果对青少年毒品使用的预防和干预有重要的理论价值和参考价值。  相似文献

采用问卷法对658名具有社交网站使用经验的大学生进行调查,考察大学生社交网站使用与依赖的关系、积极自我呈现的中介作用以及关系型自我构念的调节作用。结果发现:(1)社交网站使用能显著正向地预测大学生社交网站依赖;(2)积极自我呈现在社交网站使用与依赖的关系中起部分中介作用;(3)积极自我呈现的中介作用受到关系型自我构念的调节。具体来说,相对于高关系型自我构念的大学生,低关系型自我构念大学生的社交网站使用更多地通过积极自我呈现影响其社交网站依赖。  相似文献

We have explored how age at first intoxication with alcohol relates to mental health, social integration and adjustment to the adult role. The data stem from a longitudinal representative study of 2000 Norwegians. The sample was assessed at ages 19–22, 21–24 and 25–28. Among females, only early intoxication was related to young adult symptoms of poor mental health. A U-shaped association between intoxication debut and psychological problems was revealed among males, implying that both early and late beginners had more such problems than those who had followed the mainstream. These associations persisted without change over time. However, males who remained abstainers in adulthood were psychologically healthy, but they showed indications of a delayed entry into the adult role. Male late beginners were also somewhat reluctant to adopt adult role-behaviors. Thus, getting drunk for the first time in mid-adolescence seems to be an ingredient in the normal developmental process in young males.  相似文献

Whorf and Wittgenstein are perhaps the most famous names in linguistics and philosophy associated with the assumption that language plays a decisive role in shaping our view of reality. After a critical discussion of Whorf's linguistic relativity principle I conclude that it is not language as a system, but the use of language according to the rules of language games which connects language thought and world view, especially if some particular usage becomes the commonly accepted norm. This traditional norm also enters argumentative discourse in the form of background assumptions occuring in the premises of arguments. Thus, traditional points of view and prevailing ideologies in a society, even if challenged in discussions, can become reinforced and stabilized. This is illustrated with a critical analysis of the role and function of tautological utterances in argumentative discourse, which only apparently are compelling means of argumentation.  相似文献

This study examined the patterns of drug use and criminal activities among Latino arrestees. The findings indicate that while the prevalence of drug use at time of arrest, and in the prior 12 months were significantly lower for Latinos compared to Whites and Blacks, drug use still is of concern for this ethnic group. Almost 50% of Latinos reported drug use in the last year, and more importantly, they were more likely to report using dangerous drugs such as cocaine, heroin, and PCP than any other ethnic group. These findings are even more alarming considering that, for the most part, Latino drug users were treatment-naive, and that less than half perceived a need for drug treatment. Regarding criminal activities, Latinos were less likely to have a history of prior arrests and to have been arrested in the year prior to the interview than any other ethnic group. Interestingly, those immigrants who have resided in the U.S. for less than 1 year were significantly more likely to have been charged with drug-related crimes. U.S. born Latinos were more likely to have been arrested for property crimes, while Central American immigrants were more likely than any other Latino group to have been arrested for violent and domestic violence crimes. Treatment and policy implications of these findings are discussed.  相似文献

The interpretation of discourse covers a continuum with two extremes: on the one hand, a text considered as an ideal, distant object, and on the other hand, a conversation regarded as a real, present event. On the basis of a distinction between relatively context-invariant propositions and relatively context-dependent statements, it is argued that statements in conversational discourse are easier to interpret than statements in texts, whereas only propositions in symbolic logic can be interpreted with exactitude. In the same way, the interpretation of dialogical arguments proceeds more easily than the interpretation of arguments in texts. While dialogical argumentation requires a dialectical approach, textual argumentation necessitates an imaginative reconstruction of the argument. From this it can be concluded that for different sorts of argumentative discourse diverse sorts of interpretative activities have to be used.  相似文献

Four dimensions (applied, analytic, general, conceptual) were selected from Baer, Wolf, and Risley's (1968) seminal article on the nature of applied behavior analysis and were monitored throughout the first 10 volumes of the Journal of Applied Behavior Analysis. Each of the experimental articles in Volumes 1 through 6 and the first half of Volumes 7 through 10 was rated on each of these dimensions. The trends showed that applied behavior analysis is becoming a more purely technical effort, with less interest in conceptual questions. We are using simpler experimental designs and are conducting fewer analogue studies. Although concern for maintenance is increasing, other forms of generality are being measured or analyzed less often. These trends are discussed in terms of a technical drift in applied behavior analysis.  相似文献
