Biases in young children's communication about spatial relations: containment versus proximity 总被引：1，自引：0，他引：1
Four experiments examined 3- and 4-year-olds' ability to communicate about containment and proximity relations. One hundred twenty-eight children either described where a miniature mouse was hiding in a dollhouse or they searched for the mouse after the experimenter described where it was hiding. The mouse was always hidden with a small landmark that was either in or next to a large landmark. When describing where the mouse was hiding, children were more likely to successfully disambiguate the small landmark when it was in the large landmark (e.g., under the plant in the dresser) than when it was next to the large landmark (e.g., under the plant next to the dresser). When searching for the mouse, 3-year-olds were faster to initiate their searches when the small landmark was in the large landmark than when it was next to the large landmark. Together, these results suggest that there are informational biases in young children's spatial communication. 相似文献

The frames of reference used by 4-, 6-, and 8-year-old children were studied in a spatial direction-giving task. Children were asked to specify verbally the location of a toy hidden under one of several identical cups. The child and listener sat facing each other at opposite ends of a room that had distinctive or nondistinctive landmarks proximal and distal to the hiding location. Location needed to be specified with respect to either the left-right dimension, the front-back dimension, or both. The results indicated that (1) although children's overall performance improved with age, communication about the left-right dimension was particularly difficult for 4-year-old children and showed a higher rate of improvement with age than communication about the front-back dimension; and (2) the frames of reference that children incorporated into their directions changed with age and differed for directions about the front-back and left-right dimensions. Both 4- and 6-year-old children used person references (themselves or the listener) to specify front-back relations, but only the 6-year-olds were able to compensate for their apparent difficulty in using the terms left and right by using landmarks to specify the left-right dimension. Eight-year-olds used a combination of person and landmark references in directions about both dimensions. Discrepancies between the frames of reference children used to communicate spatial location and those typically used in other spatial cognition tasks are discussed in terms of developmental and task constraints. 相似文献

Linguistic labels play an important role in young children's conceptual organization: When 2 entities share a label, people expect these entities to share many other properties. Two classes of explanations of the importance of labels seem plausible: a language-specific and a general auditory explanation. The general auditory explanation argues that the importance of labels stems from a privileged processing status of auditory input (as compared with visual input) for young children. This hypothesis was tested and supported in 4 experiments. When auditory and visual stimuli were presented separately, 4-year-olds were likely to process both kinds of stimuli, whereas when auditory and visual stimuli were presented simultaneously, 4-year-olds were more likely to process auditory stimuli than visual stimuli. 相似文献

A Comparison of Young Children's Understanding of Contradictory Representations in Pretense, Memory, and Belief 总被引：2，自引：0，他引：2
Wendy L. Custer 《Child development》1996,67(2):678-688
The present study examined the nature of young children's understanding of various mental representations. 3- and 4-year-olds were presented with story protagonists who held mental representations (beliefs, pretenses, and memories) that contradicted reality. Subjects chose 1 of 2 alternate " thought pictures " (depicting either the mental representation or reality) that reflected the mental state. While 4-year-olds performed relatively well on all scenario types, 3-year-olds chose the correct thought picture significantly more often for pretense and memory scenarios than for false belief scenarios. These results suggest that young children conceptualize pretense as involving mental representations, and that they have more difficulty understanding contradictory mental representations that purport to correspond to reality. 相似文献

Linguistic contrast of the form "It's not X; it's Y" is often used by adults to correct children's naming errors. The present studies examined whether such linguistic contrast could help preschoolers learn a novel color name. In Experiment 1, a novel color term was contrasted only once with 1 or 2 familiar color names. Contrasting a new color term with children's own label for the stimulus color helped 5-year-olds learn the new term, but contrasting the new term with randomly chosen familiar color terms did not. For 4-year-olds, neither kind of contrast helped much. Experiments 2 and 3 showed that when the contrastive information was presented more than once, even 3- and 4-year-olds performed much like the 5-year-olds in Experiment 1. Together, these findings suggest that contrasting a new term with a child's own term facilitates the acquisition of the new term, perhaps because it gives the child specific information about how two terms are related in meaning. 相似文献

This study examined reactions of 1-year-olds and young 2-year-olds to being controlled by mothers. Mothers' supportive behavior predicted children's willing compliance. However, contrary to research with older children, defiance was also associated with variables linked to maternal competence, specifically, mothers' supportive behavior, autonomy-granting controls, and low depressive symptoms. At this age high-defiant children initiated positive interaction with mothers more than did low-defiant children. With age, children displayed more willing compliance and more active resistance (defiance, low passivity). However, developmental increases in active resistance were absent when mothers were high in depressive symptoms. Findings are consistent with the proposal that in early development active resistance to parents often reflects children's motivation to control events, not poor parenting or strained parent-child relationships. 相似文献

How Much Does a Shared Name Make Things Similar? Linguistic Labels, Similarity, and the Development of Inductive Inference 总被引：6，自引：0，他引：6
This article examines the development of inductive generalization, and presents a model of young children's induction and two experiments testing the model. The model specifies contribution of linguistic labels and perceptual similarity to young children's induction and predicts a correspondence between similarity judgment and induction of young children. In Experiment 1, 4- to 5-year-olds, 7- to 8-year-olds, and 11- to 12-year-olds were presented with triads of schematic faces (a Target and two Test stimuli), which varied in perceptual similarity, with one of the Test stimuli sharing a linguistic label with the Target, and another having a different label. Participants were taught an unobservable biological property about the Target and asked to generalize the property to one of the Test stimuli. Although 4- to 5-year-olds' proportions of label-based inductive generalizations varied with the degree of perceptual similarity among the compared stimuli, 11- to 12-year-olds relied exclusively on labels, and 7- to 8-year-olds appeared to be a transitional group. In Experiment 2 these findings were replicated using naturalistic stimuli (i.e., photographs of animals), with perceptual similarity manipulated by "morphing" naturalistic pictures into each other in a fixed number of steps. Overall results support predictions of the model and point to a developmental shift from treating linguistic labels as an attribute contributing to similarity to treating them as markers of a common category-a shift that appears to occur between 8 and 11 years of age. 相似文献

From Piaget's early work to current theory of mind research, young children have been characterized as having little or no awareness of their mental activity. This conclusion was reexamined by assessing children's conscious access to visual imagery. Four-year-olds, 6-year-olds, and adults were given a mental rotation task in the form of a computer game, but with no instructions to use mental rotation and no other references to mental activity. During the task, participants were asked to explain how they made their judgments. Reaction time patterns and verbal reports revealed that 6-year-olds were comparable to adults both in their spontaneous use and subjective awareness of mental rotation. Four-year-olds who referred to mental activity to explain their performance had reaction time and error patterns consistent with mental rotation; 4-year-olds who did not refer to mental activity responded randomly. A second study with 5-year-olds produced similar results. This research demonstrates that conscious access to at least 1 type of thinking is present earlier than previously recognized. It also helps to clarify the conditions under which young children will and will not notice and report their mental activity. These findings have implications for competing accounts of children's developing understanding of the mind and for the "imagery debate." 相似文献

These studies investigate children's use of scientific reasoning to infer the reality status of novel entities. Four- to 8-year-olds heard about novel entities and were asked to infer their reality status from 3 types of evidence: supporting evidence, irrelevant evidence, and no evidence. Experiment 1 revealed that children used supporting versus irrelevant and no evidence differentially. Experiment 2 demonstrated that children without initial reality status biases were better at evaluating evidence than were biased children. In conclusion, the ability to infer reality status from evidence develops incrementally between ages 4 and 6, and children perform better when their evaluation is free from bias. 相似文献

2 studies investigated young children's understanding that as the retention interval increases, so do the chances that one will forget. In Study 1 (24 3-year-olds and 24 4-year-olds), 4-year-olds but not 3-year-olds understood that of 2 characters who simultaneously saw an object, the character who waited longer before attempting to find it would not remember where it was. In study 2 (24 3-year-olds and 24 4-year-olds), 4-year-olds but not 3-year-olds understood that of 2 objects seen by a character, the object that was seen a "long long time ago" would be forgotten and the object seen "a little while ago" would be remembered. The findings are discussed in relation to research on young children's understanding of the acquisition, retention, and retrieval of knowledge over time. 相似文献

Two studies examined preschool teacher and child interactions regarding personal, moral, and social-conventional issues in the classroom and the development of personal concepts in young children. In Study 1, 20 preschool classrooms, 10 with 3-year-olds and 10 with 4-year-olds, were observed to assess children's and teachers' interactions regarding personal, moral, social-conventional, and mixed events. Teachers used more direct messages regarding moral and social-conventional events than personal and mixed events. Teachers offered children choices, but they rarely negotiated personal events with children. Children responded with personal choice assertions when adults offered them choices, but adults did not differ in the frequency that they negated or affirmed children's assertions of personal choice. In Study 2, 120 preschool children, nearly evenly divided between males and females at 3, 4, and 5 years of age, were interviewed regarding their conceptions of personal events in the classroom and home. With age, children judged that they should retain control over personal decisions in both contexts. In both judgments and social interactions, teachers and children identified a personal domain in which children can and should make choices about how to structure their activities and assert their independence in the classroom. 相似文献

Research suggests that young children may see a direct and one-way connection between facts about the world and epistemic mental states (e.g., belief). Conventions represent instances of active constructions of the mind that change facts about the world. As such, a mature understanding of convention would seem to present a strong challenge to children's simplified notions of epistemic relations. Three experiments assessed young children's abilities to track behavioral, representational, and truth aspects of conventions. In Experiment 1, 3- and 4-year-old children (N = 30) recognized that conventional stipulations would change people's behaviors. However, participants generally failed to understand how stipulations might affect representations. In Experiment 2, 3-, 5-, and 7-year-old children (N = 53) were asked to reason about the truth values of statements about pretenses and conventions. The two younger groups of children often confused the two types of states, whereas older children consistently judged that conventions, but not pretenses, changed reality. In Experiment 3, the same 3- and 5-year-olds (N = 42) participated in tasks assessing their understanding of representational diversity (e.g., false belief). In general, children's performance on false-belief and "false-convention" tasks did not differ, which suggests that conventions were understood as involving truth claims (as akin to beliefs about physical reality). Children's difficulties with the idea of conventional truth seems consistent with current accounts of developing theories of mind. 相似文献

The effects of object orientation and object type on children's interpretation of the word big 总被引：1，自引：0，他引：1
Previous research indicates that preschool children have persistent difficulty interpreting big: 4-5-year-olds typically interpret big to mean tall, and 3-year-olds fail to use any consistent interpretation. We propose that children's interpretation may vary depending on 2 contextual factors: type of object and orientation of object. 40 children (ages 3 and 5) each saw 35 pairs of items and, for each pair, were asked to point to "the big one." Type of object was varied by showing each child 3 kinds of objects: "people," "brownies," and rectangles. Orientation of object was varied by presenting objects either standing perpendicular to the tabletop (vertical condition) or lying flat on the tabletop (horizontal condition). Older children relied on height more consistently than younger children, all subjects relied on area more often in the horizontal condition than in the vertical condition, and 3-year-olds relied on height more when judging the bigness of people than of rectangles matched for size. Taken together, these results demonstrate that contextual factors clearly influence children's responses. These results demonstrate the interplay of cognitive and semantic factors in the process of semantic development. 相似文献

In 2 studies, we address young children's understanding of the origin and representational relations of imagination, a fictional mental state, and contrast this with their understanding of knowledge, an epistemic mental state. In the first study, 54 3- and 4-year-old children received 2 tasks to assess their understanding of origins, and 4 stories to assess their understanding of representational relations. Children of both ages understood that, whereas perception is necessary for knowledge, it is irrelevant for imagination. Results for children's understanding of representational relations revealed intriguing developmental differences. Although children understood that knowledge represents reality more truthfully than imagination, 3-year-olds often claimed that imagination reflected reality. The second study provided additional evidence that younger 3-year-olds judge that imaginary representations truthfully reflect reality. We propose that children's responses indicate an early understanding of the distinction between mental states and the world, but also a confusion regarding the extent to which mental contents represent the physical world. 相似文献

Children's magical explanations and beliefs were investigated in 2 studies. In Study 1, we first asked 4- and 5-year-old children to judge the possibility of certain object transformations and to suggest mechanisms that might accomplish them. We then presented several commonplace transformations (e.g., cutting a string) and impossible events (magic tricks). Prior to viewing these transformations, children suggested predominantly physical mechanisms for the events and judged the magical ones to be impossible. After seeing the impossible events, many 4-year-olds explained them as "magic," whereas 5-year-olds explained them as "tricks." In Study 2, we replaced the magic tricks with "extraordinary" events brought about by physical or chemical reactions (e.g., heat causing paint on a toy car to change color). Prior to viewing the "extraordinary" transformations, children judged them to be impossible. After viewing these events, 4-year-olds gave more magical and fewer physical explanations than did 5-year-olds. Follow-up interviews revealed that most 4-year-olds viewed magic as possible under the control of an agent (magician) with special powers, whereas most 5-year-olds viewed magic as tricks that anyone can learn. In a third study, we surveyed parents to assess their perceptions and conceptions of children's beliefs in magic and fantasy figures. Parents perceived their children as believing in a number of magic and fantasy figures and reported encouraging such beliefs to some degree. Taken together, these findings suggest that many 4-year-olds view magic as a plausible mechanism, yet reserve magical explanations for certain real world events which violate their causal expectations. 相似文献

The Cognitive Consequences of Collaborative Problem Solving With and Without Feedback 总被引：3，自引：0，他引：3
The goal of this research was to assess the impact of feedback, partner, and shared understanding in the course of problem solving. A sample of 180 6- to 9-year-olds was pretested to discover the children's "rule" for predicting the movement of a mathematical balance beam. For the treatment they either worked alone or with a partner who was equally, less, or more competent, with two-thirds receiving feedback from the materials. They subsequently participated in 2 individual posttests. The results revealed that children receiving feedback improved significantly more than those who did not, but that the presence of a partner was only beneficial when children received no feedback. Irrespective of feedback, those children whose partner exhibited higher-level reasoning were far more likely to benefit from collaboration than those whose partner did not, provided that the pair achieved shared understanding. 相似文献

Six match-to-sample picture/object selection experiments were designed to explore children's knowledge about superordinate words (e.g., "food") and how they acquire this knowledge. Three factors were found to influence the learning and extension of superordinate words in 3- to 5-year-old children (N = 230): The number of standards (one versus two), the type of standards presented (from different basic-level categories versus from the same basic-level category), and the nature of the object representations used (pictures versus objects). A different pattern of superordinate word acquisition was found between 3-year-olds and 4- and 5-year-olds. Although 4- and 5-year-olds could learn and extend novel words to superordinate categories in the presence of two picture exemplars from different categories or a single three-dimensional (3-D) exemplar, 3-year-olds could do so only in the presence of two 3-D exemplars. These findings indicate that young children's acquisition of superordinate words is influenced by multiple factors and that there is a developmental progression from multiple exemplars to single exemplars in superordinate word learning. 相似文献

Social Interactions in the Home and the Development of Young Children's Conceptions of the Personal 总被引：3，自引：0，他引：3
Observations and interviews of 20 middle-class 3- and 4-year-olds and their mothers were conducted to examine the emergence of the personal domain. Interviews with children showed that 3- and 4-year-olds make a conceptual distinction between personal, and moral or conventional issues. Interviews with mothers indicated that they viewed it as important for young children to have freedom of choice over personal issues to develop a sense of autonomy and individuality. Observations in the home revealed that mothers tended to give direct social messages to children about moral, conventional, and prudential events, and were more likely to give indirect social messages in the form of offered choices to children in response to personal issues. Mothers were more likely to negotiate with children over personal than other social events. These data revealed a pattern of social interactions concordant with event domain, which included a reciprocal system along the border between the personal and the conventional. 相似文献

3 studies examined young children's understanding that if one "remembers" or "forgot," one must have known at a prior time. In Study 1,4-year-olds but not 3-year-olds understood the prior knowledge component of "forgot"; both groups understood that a character with prior knowledge was "gonna remember." Study 2 controlled for the possibility that good performance on "remember" might be due to a simple association of remembering with knowledge. A significant number of 4-year-olds but not 3-year-olds understood that when 2 characters currently knew, the one with prior knowledge remembered, and that when neither character currently knew, the one with prior knowledge forgot. Study 3 made prior knowledge more salient by making the remembered or forgotten item visible to the subjects throughout. 4-year-olds performed near ceiling on both verbs, whereas 3-year-olds' performance did not differ from chance. The results are discussed in relation to children's developing understanding of the mind. 相似文献
