记忆提示与表征能力对幼儿心理理论发展的影响

本研究通过经典的错误信念任务及修正后的错误信号和错误照片任务探讨了 3、4、5岁幼儿心理理论的发展以及记忆和表征对这一发展的影响。结果表明 ,3岁儿童还没有具备像 4、5岁儿童那样的心理理论 ;记忆上的帮助并不能提高幼儿在错误信念任务上的成绩 ;所有儿童都能够很好地表征目前及过去的事件     

多元表征假设：概念表征机制的新观点

传统的认知主义认为概念表征是与主体的感知系统无关的抽象符号。而具身理论则认为,概念表征以主体的感觉、知觉运动系统为基础的,感知系统在概念表征中具有中心作用。然而,具身性假设无法恰当的解释抽象概念表征这一问题。这种局限性说明主体的概念系统可能具有多元表征机制：既包括感知表征以加工与身体经验相关的具体知识,也包括抽象符号表征以加工与身体经验无关的抽象知识。来自病理学、认知神经科学和行为实验的实证研究证明了不同类型的概念会涉及不同的表征机制,证实了多元表征存在的合理性。今后的研究应探讨各种表征机制之间的关系等问题。     

Assessing Young Children's Number Magnitude Representation: A Comparison Between Novel and Conventional Tasks

Previously, researchers have relied on asking young children to plot a given number on a 0-to-10 number line to assess their mental representation of numbers 1 to 9. However, such a (“conventional”) number-to-position (N-P) task may underestimate the accuracy of young children's magnitude estimates and misrepresent the nature of their number representation. The purpose of this study was to compare young children's performance on the conventional N-P task and a “modified” N-P task that is more consistent with a discrete-quantity view of number and with measures of theoretically related mathematical competencies. Participants (n = 45), ranging in age from 4;0 to 6;0, were administered both versions of the N-P task twice during 4 sessions in 1 of 2 randomly assigned and counterbalanced orders. Between and within conditions, children were significantly more accurate on the modified version than on the conventional task. The results indicate that the conventional task, in particular, may be confusing and that several simple modifications can make it more understandable for young children. However, when performance on theoretically related number tasks is taken into account, both the conventional and the modified N-P tasks appeared to underestimate competence.

Young Children's Knowledge of the Representational Function of Pictorial Symbols: Development Across the Preschool Years in Three Cultures

Three- to 5-year-old children's knowledge that pictures have a representational function for others was investigated using a pictorial false-belief task. In Study 1, children passed the task at around 4 years old, and performance was correlated with standard false-belief and pictorial symbol tasks. In Study 2, the performance of children from two cultural settings who had very little exposure to pictures during the first 3 years (Peru, India) was contrasted with that of children from Canada. Performance was better in the Canadian than Peruvian and Indian samples on the picture false-belief task and drawing tasks but not on the standard false-belief measure. In all settings, children passed drawing and standard false-belief tasks either concurrently with, or prior to, passing the picture false-belief task. The findings suggest that children's explicit knowledge of the representational function of pictorial symbols matures in the late preschool years and develops more rapidly in cultures that strongly promote the symbolic use of pictures early in life.     

Children's Representation and Imitation of Events: How Goal Organization Influences 3‐Year‐Old Children's Memory for Action Sequences

Children's imitation of adults plays a prominent role in human cognitive development. However, few studies have investigated how children represent the complex structure of observed actions which underlies their imitation. We integrate theories of action segmentation, memory, and imitation to investigate whether children's event representation is organized according to veridical serial order or a higher level goal structure. Children were randomly assigned to learn novel event sequences either through interactive hands‐on experience (Study 1) or via storybook (Study 2). Results demonstrate that children's representation of observed actions is organized according to higher level goals, even at the cost of representing the veridical temporal ordering of the sequence. We argue that prioritizing goal structure enhances event memory, and that this mental organization is a key mechanism of social‐cognitive development in real‐world, dynamic environments. It supports cultural learning and imitation in ecologically valid settings when social agents are multitasking and not demonstrating one isolated goal at a time.     

Young Children's Descriptions of God: Influences of parents' and teachers' God concepts and religious denomination of schools

This study extends prior research on antecedents of individual differences in God concepts in early childhood by examining relations of parents' and teachers' God concepts and religious denomination of schools with children's God concepts. Participants were 165 preschoolers (mean age 63 months), 107 of their parents and 16 teachers. These subjects were distributed over eight elementary schools belonging to four different religious denominations, i.e. Catholic, Dutch Reformed, Orthodox Reformed and State schools. The God concepts of children, parents and teachers were measured using interviews and questionnaires. Results showed that both parents' and teachers' God concepts were predictive of children's God concepts, but each in a different way. Parents seem to influence the relational component of children's God concepts particularly. Teachers especially contribute to biblical content of children's God concepts. Religious denomination of schools had independent effects on children's God concepts, controlling for parental denomination.     

质量表征和眼动过度追踪对表征动量的影响

人们对运动目标最终位置的记忆常常会向运动方向发生偏移, 这种偏移被称为“表征动量”。现有研究对表征动量的解释涉及从低水平的知觉加工到高水平的认知加工等多个方面。本研究采用不同材质和滚动声音的球体作为刺激材料, 考察高水平的质量表征对表征动量的影响以及知觉水平的眼动信息在其中的作用。实验1探讨了对目标质量的主观表征对眼动追踪和表征动量的影响。结果显示, 质量表征会同时影响眼动追踪和表征动量。实验2通过不同的提示线索控制眼动追踪, 进一步探讨眼动过度追踪对表征动量的影响。我们发现, 非自然追踪的条件下, 表征动量会减小, 且质量表征对表征动量的影响不再显著。本研究结果表明, 高水平的质量表征对表征动量的影响会通过知觉水平的眼动过度追踪起作用; 然而, 表征动量还受其它因素影响, 眼动信息并非决定表征动量的唯一因素。     

认知灵活性和顿悟表征转换：练习类型的影响

以停车场问题为实验材料,以42名大学生为被试,探讨认知灵活性高和低的被试在不同练习类型下顿悟问题表征转换的差异。结果表明：1）不同的练习类型对顿悟表征转换有影响,被试在难度逐渐增加的练习类型下比在简单的练习类型下顿悟产生得更快;2）顿悟表征转换的速度因认知灵活性的不同有差异,在简单的练习类型下,认知灵活性高的被试比认知灵活性低的被试顿悟产生得更早,在难度逐渐增加的练习类型下两者无差异;3）认知灵活性高的被试比认知灵活性低的被试顿悟问题解决更快。     

Children's Representation of Child and Adult Knowledge

Do children think that adult knowledge subsumes or only partially overlaps child knowledge? Sixty-four 4- and 6-year-old children were asked either whether a child and an adult know the answers to questions tapping adult- and child-specific knowledge (Experiment 1) or to whom each question should be addressed (Experiment 2). Children were also asked directly about the existence of child-specific knowledge. The experiments provided converging evidence that beliefs about child-specific knowledge are relatively limited among 4-year-olds but become well articulated by age 6. The findings contribute to understanding the development of children's beliefs about the relation between knowledge and age.     

Experimenter Influences and Children's Cross-Gender Behavior

We measured 120 third and fourth gradechildren's willingness to participate in severalbehavioral tasks after assessing their verbalpreferences for gender-typed and cross-gender activities(children were primarily Caucasian). Before beginning eachtask, children were either encouraged to or discouragedfrom engaging in cross-gender activities, or they wereencouraged to choose whatever activities they preferred. Relative to the control condition,experimenters were able to reduce but not increase theproportion of cross-gender activities children engagedin. Children who gave high ratings to cross-gender items during the preference test were more willingthan other children to take cross-gender selectionshome.     

Perseveration in Normal Aging: A Comparison of Perseveration Rates on Design Fluency and Verbal Generative Tasks

Three generative tasks (design generation, animal naming, words starting with m) from the Cognitive Linguistic Quick Test were administered to 73 healthy individuals in four age groups (18–39, 40–59, 60–74, 75–88) and scored for perseveration and productivity. Perseveration rates for design generation were significantly higher, and increased linearly as a function of age. The number of individuals who perseverated at least once on design generation also increased linearly, with highest prevalence in the oldest group. No age effects were found for perseveration on the verbal naming tasks. Perseverations across tasks were independent of one another. The design generation task may require multiple simultaneous processing skills, placing more demand on compromised executive processing in the elderly.     

The Roles of Emotional Comprehension and Representational Drawing Skill in Children's Expressive Drawing

The purpose of the present study was to investigate the roles of emotional comprehension and representational drawing skill in children's expressive drawing. Fifty 7‐ to 10‐year‐olds were asked to produce two (happy and sad) expressive drawings, two representational drawings (drawing of a man running and drawing of a house) and to answer the Test of Emotion Comprehension (Pons & Harris, 2000). The expressive drawings were assessed on the number of expressive subject matter themes (‘content expression’) and the overall quality of expression on a 5‐point scale. Each of the representational drawings was measured on a scale assessing detail and visual realism criteria, and contributed to a single representational drawing skill score. In line with our predictions, we found that both emotional comprehension and representational drawing skill accounted for a significant variance in children's expressive drawings. We explain that children's developing emotional comprehension may allow them to consider more detailed and poignant expressive ideas for their drawings and that their developing representational drawing skill facilitates the graphic execution of these emotional ideas.

Gender Influences on Preschool Children's Social Problem-Solving Strategies

The authors investigated gender influences on the nature and competency of preschool children's social problem-solving strategies. Preschool-age children (N = 179; 91 boys, 88 girls) responded to hypothetical social situations designed to assess their social problem-solving skills in the areas of provocation, peer group entry, and sharing or taking turns. Results indicated that, overall, girls' responses were more competent (i.e., reflective of successful functioning with peers) than those of boys, and girls' strategies were less likely to involve retaliation or verbal or physical aggression. The competency of the children's responses also varied with the gender of the target child. Findings are discussed in terms of the influence of gender-related social experiences on the types of strategies and behaviors that may be viewed as competent for boys and girls of preschool age.

Young Children's Theory of Mind and Emotion

Abstract

In three experiments, children aged 3 to 7 years were tested for their understanding of the impact of beliefs and desires on emotion. Children watched while animal characters were offered various types of container and then predicted their emotional reaction. In Experiment 1, the children (but not the characters) knew that the desirable contents of each container had been removed. The majority of 6-year-olds and a minority of 4-year-olds understood that the characters would be happy with the gift, given their mistaken belief about its contents. In Experiment 2, characters were given containers apparently containing an object they wanted but really containing an object they did not want, or vice versa. Predictions of emotion based on both the desire and the mistaken belief of the characters increased with age. In Experiment 3, characters were given closed containers that might or might not contain an item they wanted. Both 3-and 5-year-olds grasped that the characters' emotional reaction would depend on both their (unconfirmed) beliefs and desires about its content.

The experiments show that preschool children deploy a theory-like conception of mind in predicting emotional reactions. They understand that the emotional impact of a situation depends not on its objective features but on the beliefs and desires that are brought to it.     

早期儿童的游戏与心理理论的发展

选择在一日活动中儿童可自由支配的游戏时间存在明显差异的两所幼儿园,采用错误信念任务比较两园小班、中班儿童心理理论的发展状况,结果显示,半年在园经验的小班儿童在完成错误信念任务上存在显著差异,表明早期儿童的游戏,尤其是装扮游戏对儿童心理理论的发展有积极作用;但一年半在园经验的中班儿童在完成错误信念任务上不存在显著差异,由此推论儿童心理理论的发展受成熟的制约,成熟起主导作用。研究为理解幼儿园以游戏为基本活动提供了参考依据。
