从知觉分心任务看儿童类比推理能力的发展 总被引:3,自引:1,他引:2
采用四类图片类比映射任务,考察了知觉分心对90名4岁、5岁、6岁儿童类比推理能力发展的影响,并进一步阐释影响儿童类比推理能力发展的可能机制。四类图片类比映射任务分别为一种关系无分心任务、一种关系有分心任务、两种关系无分心任务和两种关系有分心任务。结果表明:(1)在具备相应知识经验的前提下,知觉分心对儿童类比推理成绩有显著影响,儿童在无分心任务中的表现明显好于知觉分心任务的表现。在无分心条件下,4岁儿童已经开始能够选择关系匹配来正确完成类比推理。错误分析发现知觉分心任务中儿童所犯错误主要是分心错误,而且分心错误随年龄增长呈下降趋势。这表明对知觉分心的抑制控制可能是儿童类比推理能力发展的一个重要影响因素。(2)随着年龄增长,儿童类比推理能力逐渐提高。总体表现为6岁组的成绩显著优于4岁、5岁组的成绩,而4岁组的成绩与5岁组的成绩没有显著差异。5岁可能是儿童能够抑制知觉分心进行类比推理的快速发展期 相似文献

Here, we investigate how activation of mental representations of categories during analogical reasoning influences subsequent cognitive processing. Specifically, we present and test the central predictions of the "Micro-Category" account of analogy. This account emphasizes the role of categories in aligning terms for analogical mapping. In a semantic priming paradigm, a four-word analogy task was compared to two other four-word tasks. Stimuli were identical in all tasks; only the instructions given to participants differed. Participants were instructed to identify analogy relations, category relations, or conventionalized semantic relations in the four-word sets. After each four-word set, a single target word appeared and participants named this word aloud. Target words that referred to category relations in the preceding four-word sets were primed as strongly when participants identified analogies as when participants identified categories, suggesting that activation of category concepts plays an important role in analogical thinking. In addition, priming of category-referent words in the analogy and category tasks was significantly greater than priming of these words when participants identified conventionalized semantic relations. Since identical stimuli were used in all conditions, this finding indicates that it is the activation of category relations, distinct from any effect of basic semantic association, that causes analogical reasoning to prime category-referent words. We delineate how the "Micro-Category" account of analogy predicts these phenomena and unifies findings from diverse areas of research concerning analogical reasoning. 相似文献

The purpose of the study was to describe the needs of foster parents for placement success. Sixty-three foster parents from a central Canadian province were asked the following question: “What do you need for a successful foster placement”? Foster parents grouped together all responses, which were analyzed using multidimensional scaling and cluster analysis procedures. Foster parents indicated that they needed the right personality and skills, information about the foster child, a good relationship with the fostering agency, individualized services, community support, linkages to other foster families, supportive immediate and extended families, as well as self-care skills. There were some differences between the existing literature and the needs identified by study participants. Differences included the need for information about policies and procedures, their treatment by professionals, and the need for formal foster parent organizations. 相似文献

A slippery slope argument is an argument to this twofold effect. First, that if a policy or practice P is permitted, then we lack the dialectical resources to demonstrate that a similar policy or practice P* is not permissible. Since P* is indeed not permissible, we should not endorse policy or practice P. At the heart of such arguments is the idea of dialectical impotence, the inability to stop the acceptance of apparently small deviations from a heretofore secure policy or practice from leading to apparently large and unacceptable deviations. Using examples of analogical arguments and sorites arguments I examine this phenomenon in the context of collapsing taboos. 相似文献

条件推理的类比转换运用 总被引:1,自引:0,他引:1
该文通过2个实验研究旨在探究将演绎推理和类比推理结合在一起的四卡条件推理的类比转换运用的特点。结果表明:1)假设检验的条件推理过程在特定的实验条件下,表现出推理过程转换的心理加工特点;2)改善问题的陈述形式,使之和样例问题一样,能够降低推理过程转换的难度,促进推理过程转换的成绩;3)2个样例归纳的图式促进同形问题的解答,却对推理转换过程有抑制作用。 相似文献

儿童问题解决中的类比迁移是儿童认知发展中的一个基本问题,但在儿童发展研究中却一直没有得到足够的重视。在对儿童问题解决中的类比迁移研究进行回顾和总结的基础上,特别是仔细分析最近十年里的类比迁移研究,该文总结出了儿童问题解决中类比迁移研究的发展趋势,主要包括从探讨迁移是否存在到验证迁移是一种早期能力、从关注迁移的年龄差异到关注促进迁移的有关因素、从关注迁移是否是基本能力到关注迁移的加工机制、从描述迁移技能到领域概化、从关注近迁移到关注远迁移。最后,该文对未来儿童问题解决中的类比迁移研究进行了展望 相似文献

In natural settings, infants learn spoken language with the aid of a caregiver who explicitly provides social signals. Although previous studies have demonstrated that young infants are sensitive to these signals that facilitate language development, the impact of real-life interactions on early word segmentation and word–object mapping remains elusive. We tested whether infants aged 5–6 months and 9–10 months could segment a word from continuous speech and acquire a word–object relation in an ecologically valid setting. In Experiment 1, infants were exposed to a live tutor, while in Experiment 2, another group of infants were exposed to a televised tutor. Results indicate that both younger and older infants were capable of segmenting a word and learning a word–object association only when the stimuli were derived from a live tutor in a natural manner, suggesting that real-life interaction enhances the learning of spoken words in preverbal infants. 相似文献
