幼儿元认知知识发展的特点

以北京市某幼儿园5个班98名幼儿为被试,利用分类和拼图任务对其元认知知识进行了测试.结果发现:3～5岁幼儿在元认知知识的某些方面表现出了一定的发展变化过程,对主体性的元认知知识、任务难度的元认知知识和策略的元认知知识的认识表现出了显著的年龄差异,特别是内部策略的运用随着年龄的增长越来越多,而对外部策略的运用越来越少.     

4～6岁儿童合作行为认知发展特点的研究

采用访谈法对119名4～6岁儿童合作行为认知的发展特点进行了研究。结果表明:(1)幼儿的合作选择认知已经达到了较高水平,其中超过一半的幼儿知道在面对问题时可以与同伴合作解决,而在日常游戏中知道与同伴合作共玩的幼儿更是超过了3.4;(2)幼儿的合作归因主要以结果归因为主,客观条件归因次之;同时,在结果归因中,幼儿主要以个体或活动归因为主,同伴关系和共同利益归因所占比例都相对较少;规则和权威归因在幼儿中仍有一定存在;(3)随着年龄的增长,幼儿合作选择认知和合作归因的水平都不断提高;(4)情境是影响幼儿合作选择认知与合作归因的一个重要因素。     

幼儿数学策略应用的发展特点及元认知的影响

本研究以幼儿数学策略应用为内容,运用实验法具体探讨了幼儿数学策略应用的年龄与性别特点,以及元认知对数学策略应用的影响。实验结果表明:(1)幼儿在解决基本算术题时,外显运算策略的使用率逐年降低,内隐运算策略的使用率明显提高,而记忆恢复策略在大班时有所发展,但直到学前班仍未占据优势;(2)女生倾向使用较初级的外显运算策略,男生倾向使用较复杂的内隐运算策略;(3)幼儿园中班、大班、学前班这三年是幼儿基本算术技能发展的重要时期,尤其学前班期间是发展的关键期;(4)不同的元认知水平直接影响着幼儿对数学策略的运用特点。     

四种注意情境下幼儿自我延迟满足的实验研究

将120名中等自控能力的3～5岁幼儿随机分配到四种注意情境下:两种奖励物同时呈现、只呈现即时奖励物、只呈现延迟奖励物、两种奖励物都不呈现,以探索幼儿自我延迟满足的注意机制及发展特点。结果发现:(1)幼儿自我延迟满足在两种奖励物都不呈现情境下平均延迟时间最长,在呈现奖励物的三种情境下平均延迟时间较短,表现出跨年龄稳定性;(2)3～5岁幼儿自我延迟满足发展存在显著年龄差异,表现出随年龄增长而提高的趋势。     

幼儿非形式推理能力的发生与发展

针对在儿童非形式推理能力发生研究中评价标准不一和研究结果中发生年龄不同的问题,在论证并提出幼儿非形式推理发生评价标准的基础上,采用提示访谈法对333名3-6岁幼儿的非形式推理做了考察。结果显示:幼儿的我方推理普遍在3岁3个月～3岁9个月发生;他方推理普遍在4岁～4岁6个月发生;反驳推理普遍在4岁9个月～6岁发生。幼儿在推理过程中提出的理由数量随年龄的增长而增多,年龄差异显著,但无显著性别差异。研究中建立的评价指标体系可以有效测量幼儿非形式推理的发生和发展。     

3～5岁幼儿基于面孔的信任判断的发展

本研究通过两个实验探讨了262名3~5岁幼儿基于面孔的信任判断能力及其年龄间差异。结果发现:(1)实验1中,当陌生面孔单张呈现时,3岁幼儿还不能正确地区分被成人评价为可信和不可信的面孔,而4、5岁幼儿已经能够基于面孔特征做出与成人基本一致的信任判断;(2)实验2中,当配对呈现可信vs.不可信两张面孔时,3~5岁幼儿都能够在日常交往情境中依据陌生交往者的面孔特征做出与成人基本一致的信任判断,并且随着年龄的增长,信任判断准确率逐步提高。这些结果表明幼儿从3岁开始已经能够基于面孔做出信任判断,随着年龄的增长,信任判断能力逐步发展。

Young children's emerging ability to make false statements

This study examined the origins of children's ability to make consciously false statements, a necessary component of lying. Children 2 to 5 years of age were rewarded for claiming that they saw a picture of a bird when viewing pictures of fish. They were asked outcome questions ("Do you win/lose?"), recognition questions ("Do you have a bird/fish?"), and recall questions ("What do you have?"), which were hypothesized to vary in difficulty depending on the need for consciousness of falsity (less for outcome questions) and self-generation of an appropriate response (more for recall questions). The youngest children (2? to 3? years old) were above chance on outcome questions, but it was not until age 3? that children performed above chance on recognition questions or were capable of maintaining false claims across question types. Findings have implications for understanding the emergence of deception in young children.     

Recognition memory across the adult life span: The role of prior knowledge

Two experiments were performed to investigate the effects of prior knowledge on recognition memory in young adults, younger old adults, 76-year-olds, and 85-year-olds. In Experiment 1, we examined episodic recognition of dated and contemporary famous persons presented as faces, names, and faces plus names. In Experiment 2, four types of faces were presented for later recognition: dated familiar, contemporary familiar, old unfamiliar, and young unfamiliar. The results of both experiments showed that young adults performed better with contemporary than with dated famous persons, whereas the reverse was true for all groups of older adults. In addition, the data of Experiment 2 indicated that (1) young adults showed better recognition for young than for old unfamiliar faces, (2) younger old adults performed better with old than with young unfamiliar faces, and (3) the two oldest age groups showed no effect of age of face. These results suggest that the ability to utilize rich semantic knowledge to improve episodic memory is preserved in very old age, although the aging process may be associated with deficits in the ability to utilize prior knowledge to support memory when the underlying representation lacks semantic and contextual features. The overall data pattern was discussed in relation to the notion that, with increasing adult age, there is an increase in the level of cognitive support required to enhance episodic remembering.     

5—7岁儿童加法策略的发展特点

随机选取72名5～7岁儿童为被试,采用实验法和访谈法对儿童解决简单加法问题的策略的发展特点进行探索。结果发现,随着年龄的增长,儿童使用提取策略明显上升,逐渐成为主导策略,而数数策略逐渐减少,凑十策略、心理算盘策略和分解策略只有在少数儿童身上发现,整体看5～7岁儿童没有出现多种策略的竞争趋势;提取和从大数开始数的策略是5～7岁儿童较为优秀的解决简单加法问题的策略。

The role of epistemic and social characteristics in children’s selective trust: Three meta‐analyses

Over the last 15 years, researchers have been increasingly interested in understanding the nature and development of children’s selective trust. Three meta‐analyses were conducted on a total of 51 unique studies (88 experiments) to provide a quantitative overview of 3‐ to 6‐year‐old children’s selective trust in an informant based on the informant’s epistemic or social characteristics, and to examine the relation between age and children’s selective trust decisions. The first and second meta‐analyses found that children displayed medium‐to‐large pooled effects in favor of trusting the informant who was knowledgeable or the informant with positive social characteristics. Moderator analyses revealed that 4‐year‐olds were more likely to endorse knowledgeable informants than 3‐year‐olds. The third meta‐analysis examined cases where two informants simultaneously differed in their epistemic and social characteristics. The results revealed that 3‐year‐old children did not selectively endorse informants who were more knowledgeable but had negative social characteristics over informants who were less knowledgeable but had positive social characteristics. However, 4‐ to 6‐year‐olds consistently prioritized epistemic cues over social characteristics when deciding who to trust. Together, these meta‐analyses suggest that epistemic and social characteristics are both valuable to children when they evaluate the reliability of informants. Moreover, with age, children place greater value on epistemic characteristics when deciding whether to endorse an informant’s testimony. Implications for the development of epistemic trust and the design of studies of children’s selective trust are discussed.
