以270名小学三~五年级儿童为被试,采用问题解决类比任务范式,探讨了小学儿童类比问题解决及策略运用的发展趋势.结果发现:(1)在儿童类比问题解决质量的发展方面,不同年级儿童差异显著,四年级儿童成绩最好;而儿童类比问题解决速度则随着年级增高而加快;(2)儿童类比策略发展更符合混合模型;随着年级发展,儿童初级、中级和高级类比策略运用逐渐增加,而非类比策略运用渐少;儿童类比策略发展的“飞跃”发生在四到五年级之间;儿童策略运用的发展呈现出多样性、竞争性、适应性的特点. 相似文献

对心理理论两成分认知模型的验证 总被引:23,自引:3,他引:20
Tager-Flusberg 和 Sullivan(2000)从主体信息加工的角度出发首次提出了一个心理理论模型,认为心理理论包括两个成分:一个是社会知觉成分,一个是社会认知成分。本研究设计了一个适合儿童特点的测查社会知觉成分的任务,将对心理理论两成分模型作进一步的验证,并对语言和心理理论两个成分的关系进行了初步探讨。被试为90名3~5岁的儿童,男女各半。结果表明心理理论的认知成分同语言相关密切,而知觉成分同语言没有表现出明显的相关。这个结果为该认知模型提供了进一步的证据 相似文献

EEG频谱相干分析发现额叶发育在童年中期存在可能的加速期。针对这一问题,本研究通过记录75名6至12岁正常儿童静坐和闭目状态下的自发脑电,分析δ、θ、α和β基本脑电频段下31对电极相干的变化情况,系统探索了该年龄段儿童额叶自发脑电频谱相干的变化特点,结果发现:θ波活动普遍强于α和β波活动;6至12岁儿童额叶内、额叶与其他脑叶间相干在整体上表现为随年龄增长而增加的趋势;额叶内、额叶与其他脑叶间相干在各频段均表现为7岁、11岁突增,10岁、12岁表现为高峰。上述结果支持6至12岁儿童额叶发育存在加速变化的结论。 相似文献

A questionnaire to assess views about spiritual development was completed by 112 of the 174 head teachers of church primary schools in Wales. The findings indicated that despite the seemingly ambiguous nature of the term ‘spiritual development’, head teachers had clear views about its meaning. While most head teachers emphasised the need for pupils to engage in their own personal spiritual search, their views differed in the extent to which they felt that promoting spiritual development meant encouraging pupils to adopt Christian beliefs. While the age and sex of head teachers was found to have no significant impact on their views; and the location and category of the school for which head teachers were responsible had only a limited impact on their view, the language of the school and the religiosity of the head teacher had a considerable impact on views regarding these matters. 相似文献

The stacking-block task has been used to assess cognitive development in both humans and chimpanzees. The present study reports three aspects of stacking behavior in chimpanzees: spontaneous development, acquisition process following training, and physical understanding assessed through a cylindrical-block task. Over 3 years of longitudinal observation of block manipulation, one of three infant chimpanzees spontaneously started to stack up cubic blocks at the age of 2 years and 7 months. The other two infants began stacking up blocks at 3 years and 1 month, although only after the introduction of training by a human tester who rewarded stacking behavior. Cylindrical blocks were then introduced to assess physical understanding in object-object combinations in three infant (aged 3-4) and three adult chimpanzees. The flat surfaces of cylinders are suitable for stacking, while the rounded surface is not. Block manipulation was described using sequential codes and analyzed focusing on failure, cause, and solution in the task. Three of the six subjects (one infant and two adults) stacked up cylindrical blocks efficiently: frequently changing the cylinders' orientation without contacting the round side to other blocks. Rich experience in stacking cubes may facilitate subjects' stacking of novel, cylindrical shapes from the beginning. The other three subjects were less efficient in stacking cylinders and used variable strategies to achieve the goal. Nevertheless, they began to learn the effective way of stacking over the course of testing, after about 15 sessions (75 trials). 相似文献

Conflicting results on children's understanding of advertising may stem from differences in research methods. Most studies are conducted using interviewing techniques, employing only verbal questioning. In the present study, 136 children of two age groups (7 and 10 years) were first asked what advertising was for and, after responding, shown depictions of possible reasons. The results indicate that although older children are more likely than younger ones to understand that advertising seeks to promote selling, pictorial cues allow a much larger proportion of all children to indicate their understanding than verbal questioning does on its own, with younger children especially showing improvement. Thus, seven‐year‐olds seem to have an implicit understanding of the persuasive intent of advertising that they are unable to articulate in response to investigators' questions. Multiple methods appear to offer a means of evaluating the level of sophistication in children' understanding of advertising. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献
