Starting in early childhood, children are socialized to be honest. However, they are also expected to avoid telling the truth in sensitive situations if doing so could be seen as inappropriate or impolite. Across two studies (total N = 358), the reasoning of 3- to 5-year-old children in such a scenario was investigated by manipulating whether the information in question would be helpful to the recipient. The studies used a reverse rouge paradigm, in which a confederate with a highly salient red mark on her nose asked children whether she looked okay prior to having her picture taken. In Study 1, children tended to tell the truth only if they were able to observe that the mark was temporary and the confederate did not know it was there. In Study 2, children tended to tell the truth only if they were able to observe that the mark could be concealed with makeup. These findings show that for children as young as age 3, decisions about whether to tell the truth are influenced by the likelihood that the information would be helpful to the recipient.  相似文献

为探究分心抑制和关系整合对学前儿童类比推理的影响,实验一先初步探究分心抑制和关系整合对25名3~4岁和26名5~6岁儿童完成含有知觉分心的类比情景任务的影响。其次,揭示知觉分心与关系整合在类比推理中的具体作用模式。实验二先初步探究分心抑制和关系整合对30名3~4岁和28名5~6岁儿童完成含有语义分心的类比情景任务的影响。其次,揭示语义分心与关系整合在类比推理中的具体作用模式。结果表明,抑制控制能显著预测儿童完成各种类型类比推理成绩,工作记忆能显著预测儿童完成含有语义分心的类比推理成绩而不能显著预测含有知觉分心的类比推理成绩。儿童完成类比情景中的分心抑制是在关系整合中完成的,当类比情景中的关系整合没有超过儿童的工作记忆容量时,知觉或语义分心才能造成对儿童类比推理的影响。  相似文献

历史唯物主义在全球化时代的适用性   总被引:1,自引:0,他引:1  
一问题的提出 今天,右派和左派知识分子都在挑战马克思主义、社会主义和历史唯物主义传统的当代适用性.右派知识分子如福山提出历史终结论,认为自由民主制度也许是"人类意识形态发展的终点"和"人类最后的一种统治形式".而左派也在质疑阶级分析和生产方式等概念是否适用于当下的历史情境.  相似文献

Content balancing is one of the most important issues in computerized classification testing. To adapt to variable-length forms, special treatments are needed to successfully control content constraints without knowledge of test length during the test. To this end, we propose the notions of ‘look-ahead’ and ‘step size’ to adaptively control content constraints in each item selection step. The step size gives a prediction of the number of items to be selected at the current stage, that is, how far we will look ahead. Two look-ahead content balancing (LA-CB) methods, one with a constant step size and another with an adaptive step size, are proposed as feasible solutions to balancing content areas in variable-length computerized classification testing. The proposed LA-CB methods are compared with conventional item selection methods in variable-length tests and are examined with different classification methods. Simulation results show that, integrated with heuristic item selection methods, the proposed LA-CB methods result in fewer constraint violations and can maintain higher classification accuracy. In addition, the LA-CB method with an adaptive step size outperforms that with a constant step size in content management. Furthermore, the LA-CB methods generate higher test efficiency while using the sequential probability ratio test classification method.  相似文献

英文阅读研究发现词长对眼跳目标选择有重要影响,阅读等词长的句子时,长词的偏好眼跳长度比短词更长。但是中文文本没有词间空格,读者难以从副中央凹获取词长信息,所以基于英文阅读得出的结果是否适用于中文阅读尚不清楚。本研究采用等词长句子阅读范式,使用全部由单字词或双字词组成的句子或由各种词长的词汇组成的混合句作为实验材料,考察词长对中文阅读眼跳目标选择的影响。结果发现,中文阅读中的眼跳长度会随词长变化而变化,双字词句的眼跳入长度和眼跳出长度均显著长于单字词句,支持了基于词中心的眼跳长度假设;同时,实验也发现混合句中的双字词的眼跳长度和双字词句中双字词的眼跳长度没有显著差异,支持了基于加工情况的眼跳目标选择策略;综合二者,说明中文阅读中,读者眼跳目标选择可能建立在副中央凹对词长信息加工的基础之上。  相似文献

类比推理这一重要认知能力能够帮助儿童在未经历过的复杂情况下进行推断和学习。近年来研究者主要从行为研究、计算机模型和眼动技术的角度探究了儿童抑制控制和工作记忆在类比推理中的交互作用模式及类比推理策略对类比推理的影响。在此基础上,研究者围绕语言标签和物理表征两方面对儿童类比推理进行了干预研究。儿童类比推理的未来研究应着眼于改进研究方法、关注类比推理各加工阶段影响因素及加强儿童类比推理策略的干预应用研究。  相似文献

近似数量系统在个体数学能力的发展中起着重要的作用, 二者之间的关系受到年龄因素的影响。主要表现为, 随着年龄的增长, 相关程度逐渐减弱, 二者之间关系的作用机制可能由基数知识中介转变为多种中介变量的共同作用。未来可采用更严格的实验设计和多种研究方法考察各年龄段儿童近似数量系统与不同数学能力之间关系的发展趋势、因果方向、关键转折点和潜在机制, 以更好地理解近似数量系统在个体数学能力发展中所起的作用。  相似文献

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias.  相似文献
