Young children's attribution of action to beliefs and desires 总被引：4，自引：0，他引：4
When and how children understand beliefs and desires is central to whether they are ever childhood realists and when they evidence a theory of mind. Adults typically construe human action as resulting from an actor's beliefs and desires, a mentalistic interpretation that represents a common and fundamental form of psychological explanation. We investigated children's ability to do likewise. In Experiment 1, 60 subjects were asked to explain why story characters performed simple actions, such as looking under a piano for a kitten. Both preschoolers and adults gave predominantly psychological explanations, attributing the actions to the actor's beliefs and desires. Even 3-year-olds attributed actions to beliefs and false beliefs, demonstrating an understanding of belief not evident in previous research. In Experiment 2, 24 3-year-olds were tested further on their understanding of false belief. They were given both false belief prediction and explanation tasks. Children performed well on explanation taks, attributing an anomalous action to the actor's false belief, even when they failed to predict correctly what action would follow from a false belief. We concluded that 3-year-olds and adults share a fundamentally similar construal of human action in terms of beliefs and desires, even false beliefs. 相似文献

Function has been considered important in numerous literatures in the study of cognitive development, yet little is known about what and how infants learn about function. Five experiments examined what 10-month-old infants (N=80) learn about functions that involve a sound produced when an object is acted on. Infants habituated to a single object (Experiment 1) or multiple objects that performed the same function (Experiment 2) learned both the actions and the sounds. Infants did not appear to learn relations between actions and sounds (Experiment 3) or appearances and sounds (Experiment 4), although they did learn the relations between appearances and actions (Experiment 5). These results are discussed in terms of how infants learn about object function. 相似文献

Both salient visual events and scene-based memories can influence attention, but it is unclear how they interact in children and adults. In Experiment 1, children (N = 27; ages 7–12) were faster to discriminate targets when they appeared at the same versus different location as they had previously learned or as a salient visual event. In contrast, adults (N = 30; ages 18–31) responded faster only when cued by visual events. While Experiment 2 confirmed that adults (N = 27) can use memories to orient attention, Experiment 3 showed that, even in the absence of visual events, the effects of memories on attention were larger in children (N = 27) versus adults (N = 28). These findings suggest that memories may be a robust source of influence on children's attention. 相似文献

This study investigated whether humans have two mind‐reading systems whereby the efficient system, unlike the flexible system, is naturally limited. There were two experiments and the first included adults as well as children (3‐ to 4‐year‐olds; total N = 128). In Experiment 1, all groups efficiently gazed in anticipation of an agent's beliefs about object location but not object identity (an ambiguous figure). In Experiment 2, children showed limits in anticipating a competitive agent's action in terms of his perspective on what is desirable. Flexibility in verbally predicting agents' actions across contexts developed with age. Convergence on signature limits across different ages and methods suggests that indirect anticipations involve minimal mind reading, whereas direct predictions tap a refined understanding of perspective. 相似文献

It is often not apparent what people ought to do. Three experiments explored cues that children and adults may use to identify conventional obligations. Experiment 1 addressed the hypothesis that young children identify obligations with expected outcomes. Although preschool-aged (4-5 years) children often expected consistency, they and school-aged (7-8 years) and adult participants indicated that obligations may be at odds with costs and benefits. In Experiment 2, all participants realized that people may have obligations they are unaware of. Preschool-aged children often used information about obligations to identify characters' beliefs. In Experiment 3, preschool but not school-aged children reliably identified obligations with the desires of authorities. The results are discussed in terms of expectations about canonical relations between mental states, outcomes, and obligations. 相似文献

2 experiments on the development of the understanding of random phenomena are reported. Of interest was whether children understand the characteristic uncertainty in the physical nature of random phenomena as well as the unpredictability of outcomes. Children were asked, for both a random and a determined phenomenon, whether they knew what its next outcome would be and why. In Experiment 1, 4-, 5-, and 7-year-olds correctly differentiated their responses to the question of outcome predictability; the 2 older groups also mentioned appropriate characteristics of the random mechanism in explaining why they did not know what its outcome would be. Although 3-year-olds did not differentiate the random and determined phenomena, neither did they treat both phenomena as predictable. This latter result is inconsistent with Piaget and Inhelder's characterization of an early stage of development. Experiment 2 was designed to control for the possibility that children in Experiment 1 learned how to respond on the basis of pretest experience with the 2 different phenomena. 5- and 7-year-olds performed at a comparable level to the same-aged children in Experiment 1. Results suggest an earlier understanding of random phenomena than previously has been reported and support results in the literature indicating an early understanding of causality. 相似文献

Two experiments attempted to resolve previous contradictory findings concerning developmental trends in false memories within the Deese-Roediger-McDermott (DRM) paradigm by using an improved methodology--constructing age-appropriate associative lists. The research also extended the DRM paradigm to preschoolers. Experiment 1 (N=320) included children in three age groups (preschoolers of 3-4 years, second-graders of 7-8 years, and preadolescents of 11-12 years) and adults, and Experiment 2 (N=64) examined preschoolers and preadolescents. Age-appropriate lists increased false recall. Although preschoolers had fewer false memories than the other age groups, they showed considerable levels of false recall when tested with age-appropriate materials. Results were discussed in terms of fuzzy-trace, source-monitoring, and activation frameworks. 相似文献

Young children's understanding of many-to-one correspondence problems was studied to illuminate the developmental transition from additive to multiplicative numerical knowledge. A many-to-one correspondence exists when a fixed number of target objects (greater than 1) is associated with each of a set of referents, as in putting 3 flowers in each of several vases. Two experiments examined effects of a brief training procedure that highlighted the iterative nature of many-to-one mappings. In Experiment 1, 5- and 6-year-old children did not benefit from the training, but a subset of 7-year-olds did. In Experiment 2, 7-year-olds showed training effects that extended to generalization problems. Patterns of performance across experimental and generalization problems suggested that some children had difficulty applying what they learned from training to the experimental problems. 相似文献

The goal of this research was to address 2 questions regarding children's use of syntactic information in acquiring verbs: First, what are children's biases for actions in the absence of syntactic information; and second, how specific is the meaning derived for verbs when syntactic information is present? In 3 experiments we presented nonsense verbs either in syntactic isolation (e.g., "Look! Sebbing!") or embedded within a transitive syntactic frame (e.g., "The frog is sebbing the duck"). These actions were then separated, and the children (mean age = 2 years, 3 months) were asked to select the action which was the referent of the verb. In Experiment 1, Causative actions (in which 1 character forces another to move in some way) were paired with Synchronous actions (in which both characters move simultaneously). In Experiment 2, the same Synchronous actions were now paired with Contact actions (in which 1 character merely touches the other). In Experiment 3, the Contact actions were paired with Causative ones. 2 results emerged: (1) Children have identifiable action biases in the absence of syntactic information and (2) these biases can be shifted by the addition of a transitive syntactic frame. We conclude that the meaning derived from the transitive frame is not specifically Causative or Contact but, more generally, a sense that 1 character is affecting another. 相似文献

Identification of distinct units within a continuous flow of human action is fundamental to action processing. Such segmentation
may rest in part on statistical learning. In a series of four experiments, we examined what types of statistics people can
use to segment a continuous stream involving many brief, goal-directed action elements. The results of Experiment 1 showed no evidence for sensitivity to conditional probability, whereas Experiment 2 displayed learning based on joint probability. In Experiment 3, we demonstrated that additional exposure to the input failed to engender sensitivity to conditional probability. However,
the results of Experiment 4 showed that a subset of adults—namely, those more successful at identifying actions that had been seen more frequently than
comparison sequences—were also successful at learning conditional-probability statistics. These experiments help to clarify the mechanisms subserving processing
of intentional action, and they highlight important differences from, as well as similarities to, prior studies of statistical
learning in other domains, including language. 相似文献

Three studies examined the effects of context on decisions about the reality status of novel entities. In Experiment 1 (144, 3- to 5-year-olds), participants less often claimed that novel entities were real when they were introduced in a fantastical than in a scientific context. Experiment 2 (61, 4- to 5-year-olds) revealed that defining novel entities with reference to scientific entities had a stronger effect on reality status judgments than did hearing scientifically oriented stories before encountering the novel entities. The results from Experiment 3 (192, 3- to 6-year-olds) indicated that definitions that support inferences facilitate reality status judgments more than do definitions that simply associate novel and familiar entities. These findings demonstrate that children share with adults an important means of assessing reality status. 相似文献

Inferring False Beliefs from Actions and Reactions 总被引：1，自引：0，他引：1
Current evidence suggests that young children have little understanding of false belief. Standard false belief tasks, however, may underestimate children's ability for 2 reasons. First, the only cue to belief in these tasks is a protagonist's lack of perceptual access to some critical event, and this may not be a very salient cue for young children. Second, the standard tasks require children to make forward-looking predictions from the causes of a belief (e.g., from what a protagonist has or has not perceived) to either the protagonist's belief or the protagonist's action, and children may not be very skilled at making such predictions. In 2 experiments we investigated whether 3-year-olds would do better on tasks in which the belief cues were stronger, and in which they could reason backward to the belief from its effects (e.g., from a protagonist's actions and reactions). Even on these easy tasks, however, they did not perform well. These findings provide strong support for the view that children of this age do not fully understand the representational nature of belief. 相似文献

In 2 experiments we asked whether training in multiple contexts could eliminate context-dependent memory retrieval at 6 months as it does for adults. We found that 24-hour retention was disrupted when infants were trained in one context and tested in another but not when they were trained in multiple contexts prior to testing in a novel context (Experiment 1). After a long delay, however, training in multiple contexts did not facilitate memory retrieval in a novel context: An otherwise effective retrieval cue (the training mobile) did not alleviate forgetting 3 weeks later when it was presented in a novel context (Experiment 2). These findings demonstrate that multiple learning contexts can override the debilitating effects of an altered context on memory retrieval at 6 months, but only over the short term. The resistance of older memories to retrieval in novel contexts after long periods of disuse may be adaptive, insuring that potentially inappropriate or irrelevant memories will not be expressed. 相似文献

Despite considerable debate about whether nonhuman primates learn to use tools via imitation, this type of learning by children has received surprisingly little attention. The findings of two studies that go some way toward filling this gap are reported here. Study 1 showed that when 2- and 3-year-old children (N = 68) were shown a correct solution to a tool-using task (which they could not solve spontaneously), all the children in both age groups managed at least a partial solution. When children were shown an incorrect solution followed by a correct solution, 2-year-olds again produced only a partial solution. By contrast, most 3-year-olds produced a full solution. Study 2 replicated this age change in a separate sample of children (N = 100) with a different tool-using task. Study 2 also showed that 3-year-olds benefit from observing an incorrect action when it can be contrasted with a correct action: they chose the more effective of the two actions. Taken together, the two studies indicate that by 3 years of age, children do not indiscriminately imitate actions on a tool, but selectively reproduce those actions that have a desired causal effect. 相似文献

Young Children's Comprehension of Pretend Episodes: The Integration of Successive Actions 总被引：3，自引：0，他引：3
In 3 experiments, children's comprehension of successive pretend actions was examined. In Experiment 1, children (25–38 months) watched 2 linked actions (e.g., a puppet poured pretend cereal or powder into a bowl, and then pretended to feed the contents of the bowl to a toy animal). Children realized that the pretend substance was incorporated into the second action. In Experiment 2, children (24–39 months) again watched 2 linked actions (e.g., a puppet poured pretend milk or powder into a container, and then pretended to tip the contents of the container over a toy animal). They realized that the animal would become "milky" or "powdery." In Experiment 3, children (25–36 months) drew similar conclusions regarding a substitute rather than an imaginary entity. The results are discussed with reference to children's causal understanding, their capacity for talking about objects and events in terms of their make-believe and real status, and the processes underlying pretense comprehension. 相似文献

Two studies examined whether children (5- and 6-year-olds; 8- and 9-year-olds, n = 214) and adults (n = 72) consider social relationship when evaluating unhelpful or helpful actions. Participants learned about a person-in-need who was (or was not) helped by someone they knew (a friend) and someone they did not know (a stranger). Older children and adults judged an unhelpful friend as meaner than an unhelpful stranger, and judged a helpful stranger as nicer than a helpful friend. Younger children did not judge an unhelpful friend as any meaner than an unhelpful stranger, and they judged a helpful friend as nicer than a helpful stranger. These findings suggest that a mature appreciation of how social relationship matters for evaluation emerges relatively late in development. 相似文献

We conducted a survey to compare a group of older adults’ and a group of younger adults’ beliefs regarding their own and each other's memory abilities. We also asked both age groups to identify items they believed older adults remember well. The survey was returned by 185 older (ages 60‐92) and 184 younger (ages 17‐39) participants. Of the 30 items we generated older adults reported that they would remember 23 better than younger adults would and 7 worse than younger adults would, and younger adults reported that they would remember 12 of the items better and 18 of them worse than older adults. Both age groups also generated many items that they believed older adults remember better than younger adults do. Finally, respondents generated items that they believed adults in their own age group had to remember routinely that adults in the other age group did not. The two groups agreed that older adults would spend more time and have more difficulty learning lines for presentation to an audience than would younger adults. Most of the older adults reported that their memories had changed; most of the younger adults reported that their memories had not changed. The belief that although older adults’ memory is worse than young adults’ they still remember some things better than the young is viewed as a realistic assessment, and implications for future research are discussed. 相似文献
