Reflection on the relationship between a sign and its meaning (i.e. semiotic activity) is a fundamental form of cognitive activity that already occurs at an early age. The improvement of this semiotic activity in young children prepares for their later learning activity. Iconic representations are one important category of signs for young children (3‐7 years old). Iconic representations (drawings, diagrams, schemes) are generally conceived of as means bridging the gap between early enactive, perception‐bound thinking and abstract‐symbolical thinking. From the Vygotskian perspective iconic representations are complex signs referring to some object (situation, action) in a special way. On the bases on the analysis of children's drawings it is argued that iconic representations are narrative in nature for young children. Children tend to supplement their drawings with verbal symbols in order to make sure that their intended meanings are maximally clear. In doing so, children learn to carry out semiotic activity and improve this activity with the help of more abstract symbols 相似文献

This article is part of a larger project focusing upon explanatory illustrations that children encounter in pre- and primary school education. The research questions concerned (a) how preschool children make sense of iconic symbols when placing items of refuse on illustrations of refuse bins in a sorting task and (b) what stumbling blocks they encounter when interpreting these symbols. Video data were collected with 30 children between four and five?years of age. From the children’s verbal and non-verbal interactions, four different categories of sense-making were constructed: by material, by object type, by appearance and by function. Three stumbling blocks were identified. The first had to do with giving the symbols a different logical meaning to the intended one; the second related to what materials the different refuse items were made of; the third was being able to stick to one correct way of interpreting each symbol. 相似文献

Children often find it difficult to map verbs to specific referents within complex scenes, often believing that additional features are part of the referents. This study investigated whether 3‐year‐olds could use iconic gestures to map novel verbs to specific referents. One hundred and twenty children were taught verbs that could be interpreted as change‐of‐state or manner verbs while presented with manner, end‐state, or no iconic gestures. Children were then presented with a choice that forced them to generalize either on the basis of manner or end state. Results showed that children who saw manner gestures showed a stronger manner bias compared to the other groups. Thus, the specific feature of an event encoded in gestures guides children's interpretations of novel words. 相似文献

In 4 experiments 120 three- to four-year-old nonreaders were asked the identity of a symbolic representation as it appeared with different objects. Consistent with Bialystok (2000), many children judged the identity of written words to vary according to the object with which they appeared but few made such errors with recognizable pictures. Children also made few errors when the symbols were unrecognizable pictures. In Experiments 2 to 4 this pattern of responses was preserved in conditions that made it unlikely or impossible for children to answer correctly by taking the symbol to refer to one of the objects with which it appeared. Instead, correct answers required children to appreciate that the symbol had a generic, abstract meaning. 相似文献

Research Findings: The present study examined associations between children’s classroom interactions and teachers’ perceptions of teacher–child relationships during 1 year of preschool. Teachers (n = 223) reported their perceptions of closeness and conflict in their teacher–child relationships in the fall and spring. Children’s (n = 895) positive classroom interactions with teachers, peers, and learning activities and their negative interactions were observed midyear. Children’s positive interactions with teachers and learning activities predicted teachers’ perceptions of more closeness in the spring when we accounted for fall closeness. Children’s negative interactions predicted teachers’ perceptions of more relational conflict in the spring when we accounted for fall conflict. Children’s positive peer interactions did not predict spring closeness or conflict. Implications regarding teachers’ perceptions of teacher–child relationships and children’s independently observed classroom interactions are discussed. Practice or Policy: Findings provide empirical evidence for an aspect of Pianta, Hamre, and Stuhlman’s (2003) conceptual model of teacher–child relationships. Results indicate that children’s classroom interactions may be a factor related to how teachers report on their relationships with children across 1 year of preschool. Findings point to links between a range of children’s positive and negative interactions during typical instruction and teachers’ relationship perceptions. 相似文献

"指事"是一种重要的造字方法,历来为汉字学者所重视。但是,由于许慎"视而可识,察而见意"八字界说过于简单且纰漏较多,致使后人对"指事"的理解有颇多分歧。通过阐释检讨明儒赵撝谦《六书本义·指事论》并综合古今方家观点,我们发现,指事字既是对象形字字符资源的利用,又是对象形构形造字法的深化。指事字利用象形字形符象征某类物体的"能指"功能,通过添加特定的指示符号借以表达新的语义,在充分展现象形字潜在的能指性功能的基础上,使汉字的所指功能得以充分发挥。 相似文献

Pictorial symbols such as photographs, drawings, and maps are ubiquitous in modern cultures. Nevertheless, it remains unclear how children relate these symbols to the scenes that they represent. The present work investigates 4‐year‐old children's (N = 144) sensitivity to extended surface layouts and objects when using drawings of a room to find locations in that room. Children used either extended surfaces or objects when interpreting drawings, but they did not combine these two types of information to disambiguate target locations. Moreover, children's evaluations of drawings depicting surfaces or objects did not align with their use of such information in those drawings. These findings suggest that pictures of all kinds serve as media in which children deploy symbolic spatial skills flexibly and automatically. 相似文献

Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed. 相似文献

Emotional expressions are abundant in children’s lives. What role do they play in children’s causal inference and exploration? This study investigates whether preschool-aged children use others’ emotional expressions to infer the presence of unknown causal functions and guide their exploration accordingly. Children (age: 3.0–4.9; N = 112, the United States) learned about one salient causal function of a novel toy and then saw an adult play with it. Children explored the toy more when the adult expressed surprise than when she expressed happiness (Experiment 1), but only when the adult already knew about the toy’s salient function (Experiment 2). These results suggest that children consider others’ knowledge and selectively interpret others’ surprise as vicarious prediction error to guide their own exploration. 相似文献

象似性手势是指在形式和表达方式上与其所伴随的言语的语义内容密切相关的手势。儿童通常在18~24个月产生象似性手势,到3岁时能准确理解象似性手势的含义。象似性手势的产生和理解与儿童年龄呈正相关,且受文化等社会因素的影响较大。象似性手势能够揭示儿童的象征发展水平,解释并再现言语组织过程,补充言语中未表达的信息,促进多通道表征,提高词汇加工效率,因而有助于儿童的词汇理解、记忆和泛化。未来相关研究应进一步扩大象似性手势的研究对象,考察象似性手势与具身认知的关系及其对儿童词汇学习的多方面影响,这将有助于提高未来研究成果对教育实践的指导作用。 相似文献

Preschool children can navigate by simple geometric maps of the environment, but the nature of the geometric relations they use in map reading remains unclear. Here, children were tested specifically on their sensitivity to angle. Forty‐eight children (age 47:15–53:30 months) were presented with fragments of geometric maps, in which angle sections appeared without any relevant length or distance information. Children were able to read these map fragments and compare two‐dimensional to three‐dimensional angles. However, this ability appeared both variable and fragile among the youngest children of the sample. These findings suggest that 4‐year‐old children begin to form an abstract concept of angle that applies both to two‐dimsional and three‐dimensional displays and that serves to interpret novel spatial symbols. 相似文献

Research Findings: Prior research indicates that shared book reading is an effective method for teaching biological concepts to young children. Adult questioning during reading enhances children’s comprehension. We investigated whether adult prompting during the reading of an electronic book enhanced children’s understanding of a biological concept. Ninety-one 4-year-olds read about camouflage in 3 conditions. We varied how prompts were provided: (a) read by the book, (b) read by a researcher, or (c) given face to face by the researcher. There was an interaction between children’s initial vocabulary level and condition. Children with low vocabulary scores gave fewer camouflage responses than their high-vocabulary peers, and this effect was particularly pronounced in the book-read condition. Children’s executive function was also measured and discussed. Practice or Policy: Our findings indicate that under some circumstances electronic prompts built into touchscreen books can be as effective at supporting conceptual development as the same prompts provided by a coreading adult. However, children with low vocabulary skills may be particularly supported by adult-led prompting. We suggest that adult prompting be used to motivate children to test and revise their own biological theories. Once children have learned strategies for updating their concepts, electronic prompting may be useful for scaffolding children’s transition to using the strategies when reading alone. 相似文献

This study investigated whether seeing iconic gestures depicting verb referents promotes two types of generalization. We taught 3- to 4-year-olds novel locomotion verbs. Children who saw iconic manner gestures during training generalized more verbs to novel events (first-order generalization) than children who saw interactive gestures (Experiment 1, N = 48; Experiment 2, N = 48) and path-tracing gestures (Experiment 3, N = 48). Furthermore, immediately (Experiments 1 and 3) and after 1 week (Experiment 2), the iconic manner gesture group outperformed the control groups in subsequent generalization trials with different novel verbs (second-order generalization), although all groups saw interactive gestures. Thus, seeing iconic gestures that depict verb referents helps children (a) generalize individual verb meanings to novel events and (b) learn more verbs from the same subcategory. 相似文献

Research Findings: Effects on children’s school readiness were evaluated for 2 interventions focused on improving teacher–student interactions (coursework, coaching) implemented sequentially across 2 years. Teachers from public prekindergarten programs in 10 locations were assigned randomly to treatment or control conditions in each year. Children’s language behavior was observed during the coaching year: Coaching and the course each had positive impacts on children’s multiword language behavior. Treatment impacts on directly assessed literacy, language, and self-regulation skills were evaluated within an intent-to-treat framework for children taught by the participating teachers in the coaching and postcoaching years. Children demonstrated higher levels of inhibitory control in direct assessments when their teacher had received coaching the prior year. Teachers who received both coursework and coaching reported in the postcoaching year that children in their classrooms demonstrated greater levels of behavioral control. Treatment effects did not differ as a consequence of child, classroom, or program characteristics, and there were no significant effects on directly assessed literacy or language skills. Practice or Policy: Results suggest modest benefits for children’s language behavior and self-regulation for intervention(s) that improve the quality of teacher–child interaction. 相似文献

Research Findings: This study examined the contribution of several class-room experience measures (classroom characteristics, teacher characteristics, and teacher–child interactions) to preschoolers’ improvement in visuomotor integration. Children (N = 467) ranged in age from 3 to 5 years old and were enrolled in 115 classrooms in 5 U.S. states. Children’s visuomotor integration was measured twice (on average 5.2 months apart) using the Beery-Buktenica Developmental Test of Visual-Motor Integration (visuomotor integration subtest). Hierarchical linear models controlling for background characteristics and inhibitory control showed that children improved more in visuomotor integration when they were in classrooms with fewer 3-year-olds, when their teacher had at least a bachelor’s degree, and when teachers demonstrated high quality in their interactions. Practice or Policy: Visuomotor integration, and specifically the ability to copy designs with a writing utensil, is a robust indicator of children’s school readiness and longitudinal achievement. U.S. preschoolers gained more on visuomotor integration in classrooms with fewer 3-year-old children that were taught by a college-educated teacher and when such classrooms provided high-quality organizational and instructional interactions. These results expand the outcomes linked to early childhood education experiences and emphasize the need for well-prepared early childhood teachers who interact with children effectively. 相似文献

索绪尔认为任意性是语言符号系统的第一原则,但象似性学派认为语言符号是非任意的,两者对语言符号性质的看法形成了对立。实际上,任意性和象似性处于语言的两个层级,它们并不是相互对立的。语言的上层是语言符号运用的动态层面,是共时系统内部符号与符号的组合关系,所以是任意的;语言的底层是语言符号产生的静态层面,是从历时系统角度观察到的语言符号形成的源头和根据,所以是象似的。因此,两者谁也不能否定谁。 相似文献

Children’s naive theories include misconceptions which can interfere with science learning. This research examined the effect of pairing anomalies with alternative theories, and their order of presentation, on children’s belief revision. Children believe that heavy objects sink and light ones float. In a pre-, mid-, and post-test design, 5-year-olds (N = 96) were assigned to one of two conditions, where they were either exposed to an alternative theory about buoyancy and then observed anomalies (Explanation-First), or the reverse (Anomalies-First). At mid-test, children were more likely to revise their beliefs after exposure to an alternative theory than anomalies alone. At post-test, children revised their naïve belief when they had access to an alternative theory before the anomalous evidence than in the opposite order. 相似文献

The present study investigated children’s colour use in drawing tasks specifying single and mixed emotions. One hundred and eighty children (90 girls and 90 boys) between 4?years 11?months and 8?years 1?month (X?=?6?years 6?month) participated. All children completed two test sessions in counterbalanced order. Session A measured emotional understanding and colour use in relation to a brief story. Children’s colour preferences were measured in Session B. Children used colours differentially across the drawing types and varied colour use in relation to depictions of other people and themselves using red and blue when depicting a protagonist with mixed emotions and red when depicting their own experiences of mixed emotion. The findings are discussed in terms of the need for caution when interpreting multiple and singular colour–affect associations in children’s drawings and the need to further investigate children’s understanding and non-verbal expression of mixed emotion. 相似文献

Research Findings: Children learn most of their vocabulary incidentally, by hearing words used in their environment. This study explored which kinds of presentations of words, without any direct instruction, yielded greater depth of target word knowledge. Changes in 56 kindergartners’ depth of knowledge for each of 23 novel target words (N = 1,288) based on presentation in 1 of 3 conditions (read-aloud, teacher conversation, or both read-aloud and conversation) were explored and compared to control words that were never presented. A 2-level, cross-classification analysis modeled the postintervention score for each word for each child. Children’s word meaning knowledge improved most when words were presented via combined conversations and read-alouds. Vocabulary gains for words presented via conversations differed across classrooms. Practice or Policy: Both teacher conversations and read-aloud presentations of target vocabulary should be used together. Professional development for teachers’ effective vocabulary conversations may be needed. 相似文献
