Young children sometimes act inappropriately despite appearing to know what to do. Dissociations of this kind raise important questions about the organization and development of knowledge and action systems. The present study investigated a knowledge–action dissociation in 6–year–olds performing a speech interpretation task and tested the hypothesis that knowledge–action dissociations stem from a general difficulty resolving conflicting cues. When knowledge and action measures were equated in terms of the amount of conflict that needed to be resolved for a correct response, children’s knowledge no longer appeared to outstrip their ability to act appropriately. Implications of the findings for competing views of knowledge representation and knowledge–action system organization are discussed.  相似文献

The Dimensional Change Card Sort (DCCS) task requires children to switch from sorting cards based on shape or color to sorting based on the other dimension. Typically, 3-year-olds perseverate, whereas 4-year-olds flexibly sort by different dimensions. Zelazo and colleagues (1996, Cognitive Development, 11, 37-63) asked children questions about the postswitch rules and found an apparent dissociation between rule knowledge and rule use, namely that 3-year-olds demonstrate accurate knowledge of the postswitch rules despite sorting cards incorrectly. Here, we show that children's success with these questions is grounded in their use of available visual cues; children who fail sorting use the target cards to correctly answer questions, and when the cards are unavailable they guess. This suggests that there might not be a dissociation between children's rule knowledge and rule use in the DCCS.  相似文献

Five experiments were conducted to examine the impact of question wording manipulations derived from face management theory (Brown & Levinson, 1987) on responses to survey questions. In general, it was expected that questions phrased so as to allow the respondent to maintain face while answering in a socially undesirable manner would result in lower rates of socially desirable responding than would control questions. The results strongly supported this hypothesis for questions regarding socially desirable knowledge (e.g., Are you familiar with NAFTA?), but not for questions about socially desirable behavior (e.g., Did you vote?). The results were partially supportive for questions about socially undesirable behaviors (e.g., Have you ever shoplifted?).  相似文献

Eighty children in kindergarten and grades 3, 6, and 8 were interviewed regarding their understanding of adult drinking and their knowledge of the rules of drinking. Understanding of adult drinking motives was assessed by asking them to interpret drinking episodes portrayed in brief vignettes. Their knowledge of drinking rules was inferred from answers to questions on where people drink, who can drink, how much is a lot to drink, and who decides the age of legal drinking. Children were also given a series of questions to assess their knowledge of physical causality. In addition, their parents were interviewed to determine their drinking frequency (in view of the children) and their attempts to talk with their children about drinking. The results indicated that children's understanding of adults' drinking motives followed closely a developmental model. Their motive scores were correlated with physical causality scores and, in the third grade, with their parents' drinking frequency. Girls' motive scores were significantly and consistently more mature than boys' scores. Furthermore, there was a significant relationship between children's stated intentions to drink and their parents' drinking frequency. The results are discussed in terms of the complexity of the concept of drinking; different dimensions have different developmental functions. Some aspects of drinking knowledge conform to other cognitive developmental phenomena (e.g., physical causality) while others are related to specific social context (e.g., parental drinking).  相似文献

We replicated Shillingsburg et al. (2018) by teaching children with autism to mand for social information while analyzing the variables influencing the emission of mands. We presented questions about a social partner that were known and observable (e.g., “What is Robin doing?”), known but unobservable (i.e., questions for which an intraverbal response had previously been taught, such as, “Where does Robin work?”), or unknown (e.g., “What is Robin's favorite food?”). Correct answers were reinforced across all conditions. During treatment, we prompted children to mand for information from the social partner following only unknown questions. All children acquired mands for social information and answered previously unknown questions correctly after manding for social information and 3 of 4 participants emitted mands to novel social partners, including a peer with autism.  相似文献

Children often extend names to novel artifacts on the basis of overall shape rather than core properties (e.g., function). This bias is claimed to reflect the fact that nonrandom structure is a reliable cue to an object having a specific designed function. In this article, we show that information about an object's design (i.e., about its creator's intentions) is neither necessary nor sufficient for children to override the shape bias. Children extend names on the basis of any information specifying the artifact's function (e.g., information about design, current use, or possible use), especially when this information is made salient when candidate objects for extension are introduced. Possible mechanisms via which children come to rely less on easily observable cues (e.g., shape) and more on core properties (e.g., function) are discussed.  相似文献

Across the world's languages two quite different systems are used in answering negative questions such as Aren't you going? In English the speaker answers yes or no depending on the speaker's intention about the matter (e.g., Yes, I am going, if the speaker intends to go). In Japanese, the speaker answers yes or no in agreement or disagreement with the literal statement of the question (e.g., No, I am going, if the speaker is going and thus disagrees with the literal form of the question). One purpose of this study was to see which of these linguistic systems is acquired earlier. The other was to see whether the two systems work independently in bilingual children. The data on positive and negative questions from English and Japanese monolingual children showed that the English system is easier to acquire and the data from Japanese-English bilingual children showed that they used the English system to answer Japanese negative questions. The results suggest that the English system is acquired earlier than the Japanese system and that the two systems interact in bilingual children. These results were discussed in terms of sentence verification models.  相似文献

Thematic relations in adults' concepts   总被引:8,自引:0,他引:8  
Concepts can be organized by their members' similarities, forming a kind (e.g., animal), or by their external relations within scenes or events (e.g., cake and candles). This latter type of relation, known as the thematic relation, is frequently found to be the basis of children's but not adults' classification. However, 10 experiments found that when thematic relations are meaningful and salient, they have significant influence on adults' category construction (sorting), inductive reasoning, and verification of category membership. The authors conclude that concepts function closely with knowledge of scenes and events and that this knowledge has a role in adults' conceptual representations.  相似文献

The dimensional change card-sorting task (DCCS) is used to assess the executive abilities of young children. Typically, 3-year-olds have difficulty in performing this task. However, the exact nature of this difficulty is still being debated. In the standard DCCS, children need to sort, for example, test cards with a blue flower or a red car into two boxes marked with the target cards. The 3-year-olds commonly have pronounced difficulty in switching from one sorting criterion (e.g., color) to another (e.g., shape). Here two experiments with 3-year-olds showed that making the transition between the sorting criteria more distinct improved performance significantly. This was achieved by taking away the target cards for a brief time period, asking a question irrelevant to the task, and pretraining the children by redescribing the test cards.  相似文献

Generic noun phrases ("Birds lay eggs") are important for expressing knowledge about abstract kinds. The authors hypothesized that genericity would be part of gist memory, such that young children would appropriately recall whether sentences were presented as generic or specific. In 4 experiments, preschoolers and college students (N = 280) heard a series of sentences in either generic form (e.g., "Bears climb trees") or specific form (e.g., "This bear climbs trees") and were asked to recall the sentences following a 4-min distractor task. Participants in all age groups correctly distinguished between generic and specific noun phrases (NPs) in their recall, even when forgetting the details of the NP form. Memory for predicate content (e.g., "climb trees") was largely unaffected by genericity, although memory for category labels (e.g., "bear") was at times better for those who heard sentences with generic wording. Overall, these results suggest that generic form is maintained in long-term memory even for young children and thus may serve as the foundation for constructing knowledge about kinds.  相似文献

In this paper we describe dissociations of implicit versus explicit access to semantic information in a patient with deep dyslexia. This acquired reading disorder is characterized by the production of morphological (e.g., SLEEP read as SLEEPING) and semantic errors (e.g., HEART read as BLOOD) and consequently provides a potential window into the operation of both aspects of the language system. The deep dyslexic patient in this study (JO) demonstrated implicit semantic access to items in a number of tasks despite the fact that she was unable to correctly read these items aloud. The findings from this study are consistent with a model of lexical deficits that distinguishes between explicit and implicit access to lexical representations on the basis of inhibitory processes.  相似文献

Children are interviewed to provide information about past events in various contexts (e.g., police interviews, court proceedings, therapeutic interviews). During an interview, various factors may influence the accuracy of children's responses to questions about recent events. However, behavioral research in this area is limited. Sparling et al. (2011) showed that children frequently provided inaccurate responses to questions about video clips they just watched depending on the antecedents (i.e., the way a question was asked) and consequences (i.e., the response of the interviewer to their answers). In the current study, we replicated and extended the procedures reported by Sparling et al. and found that two of five children were sensitive to the various antecedents and consequences that we manipulated. Our findings indicate a need for more research in this area to determine the relevant environmental variables that affect children's response accuracy.  相似文献

Michaels's (2000) reassessment of the relation between action and perception is endorsed. In alignment with Milner and Goodale (1995), she proposed a separation between action (i.e., control of movement) and perception (i.e., the explicit knowledge of environmental properties, including animal-referential ones), the separation being based on the reliance on different optical variables. However, how should the concept of affordances be incorporated into this scheme? We present data showing that affordances, both when perceived and acted on, are not susceptible to optical illusions. Because action and perception are distinguished on the basis of information used, but are also proposed to interact, it is hypothesized that, dependent on the task goal, "information for action" may be used in perception, and "information for perception" may be used in action. Participants may become more attuned to information for action when perception serves to acquire explicit knowledge about what the environment affords for action.  相似文献

In recognition tests, items presented in unusual ways (e.g., degraded, revealed in stages, or presented as anagrams) are often judged to be old more than are intact items. This revelation effect has been observed only in episodic judgments about the occurrence or frequency of relatively recent events. The present work extends the boundary conditions of this effect. In three experiments, subjects unscrambled anagrams in the context of answering questions about their childhood (e.g., broke a dwniwo playing ball) or while answering questions pertaining to world knowledge (e.g.,fastest animal-elpraod). In each case, a revelation effect was observed: Solving an anagram increased confidence in remote autobiographical memories and in memory for world facts. These results contradict claims that the effect is an episodic memory phenomenon and challenge existing explanations of the revelation effect.  相似文献

Four experiments investigated how people's perceptions about a group's (e.g., women's) vulnerability to a disease are influenced by information about the prevalence of the disease in a comparable group (e.g., men). Participants read symptom and prevalence infomation about fictitious diseases before answering questions regarding target group vulnerability. Participants used the prevalence rate for a nontarget group as an immediate comparison standard for intuitively interpreting the degree of vulnerability of a target group, resulting in robust contrast effects. Experiments 3 and 4 illustrated that these contrast effects can cause a person's intuitive perceptions about a group's vulnerability to selected diseases to conflict with his or her knowledge of the prevalence rates for the diseases. The results support a distinction between 2 components of psychological uncertainty-beliefs in objective probability and more intuitive perceptions of certainty.  相似文献

The purpose of this investigation was to evaluate the possible presence of dissociations in the speech and language skills of young children who do (CWS) and do not stutter (CWNS) using a correlation-based statistical procedure [Bates, E., Appelbaum, M., Salcedo, J., Saygin, A. P., & Pizzamiglio, L. (2003). Quantifying dissociations in neuropsychological research. Journal of Clinical and Experimental Neuropsychology, 25, 1128-1153]. Participants were 45 preschool CWS and 45 CWNS between the ages of 3;0 and 5;11 (years;months), with the two groups matched by age, gender, race, and parental socioeconomic status. Children participated in a parent-child interaction for the purpose of disfluency analysis and responded to four standardized speech-language tests for subsequent analyses as main dependent variables. Findings indicated that CWS were over three times more likely than CWNS to exhibit dissociations across speech-language domains, with 44 cases of dissociation for CWS and 14 for CWNS across 10 possible comparisons. Results suggest that there may be a subgroup of CWS who exhibit dissociations across speech-language domains, which may result in a greater susceptibility to breakdowns in speech fluency. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) summarize findings from previous studies examining differences in speech and language performance between children who do and do not stutter; (2) describe what is meant by "dissociations" in the speech and language skills of young children who do and do not stutter; and (3) discuss three hypotheses that could account for the present findings that suggest CWS, more often than CWNS, exhibit dissociations in their speech-language system.  相似文献

The ability to explain the occurrence of errors in children's speech is an essential component of successful theories of language acquisition. The present study tested some generativist and constructivist predictions about error on the questions produced by ten English-learning children between 2 and 5 years of age. The analyses demonstrated that, as predicted by some generativist theories [e.g. Santelmann, L., Berk, S., Austin, J., Somashekar, S. & Lust. B. (2002). Continuity and development in the acquisition of inversion in yes/no questions: dissociating movement and inflection, Journal of Child Language, 29, 813-842], questions with auxiliary DO attracted higher error rates than those with modal auxiliaries. However, in wh-questions, questions with modals and DO attracted equally high error rates, and these findings could not be explained in terms of problems forming questions with why or negated auxiliaries. It was concluded that the data might be better explained in terms of a constructivist account that suggests that entrenched item-based constructions may be protected from error in children's speech, and that errors occur when children resort to other operations to produce questions [e.g. Dabrowska, E. (2000). From formula to schema: the acquisition of English questions. Cognitive Liguistics, 11, 83-102; Rowland, C. F. & Pine, J. M. (2000). Subject-auxiliary inversion errors and wh-question acquisition: What children do know? Journal of Child Language, 27, 157-181; Tomasello, M. (2003). Constructing a language: A usage-based theory of language acquisition. Cambridge, MA: Harvard University Press]. However, further work on constructivist theory development is required to allow researchers to make predictions about the nature of these operations.  相似文献

In this article, we explore the nature of the conceptual knowledge retrieved when people use words to think about objects. If conceptual knowledge is used to simulate and guide action in the world, then how one can interact with an object should be reflected in the speed of retrieval and the content that is retrieved. This prediction was tested in three experiments in which a part verification procedure was used. Experiments 1 and 2 demonstrated that speed of part verification varied with the perspective imposed on the object by the language used to name the object (e.g., "You are driving a car" or "You are fueling a car"). In Experiment 3, parts were chosen so that actions directed toward them (on the real object) require movement upward (e.g., the roof of a car) or downward (e.g., the wheels of a car). Orthogonally, responding "yes" required an upward or a downward movement to a response button. Responding in a direction incompatible with the part's location (e.g., responding downward to verify that a car has a roof) was slow relative to responding in a direction compatible with the part's location. These results provide a strong link between concept knowledge and situated action.  相似文献

Cognitive flexibility is a hallmark of human cognition, but its development is still poorly understood. The present work examined the flexibility of categorization in preschool children. Thirty-three participants aged 3–4 years were divided into three groups, with each group receiving a different version of a flexible categorization task in which the targets belonged to two distinct categories. These versions manipulated the type of questions that were asked and the alternation of shape and color games. The children exhibited flexibility when the questions were specific (or asked about attributes). The results support the idea that instructions play a role in children’s performance in sorting tasks. Considering cognitive flexibility as an expression of the interaction between children’s knowledge and abilities on the one hand and the structure, specifics, or demands of the task on the other can help clarify what cognitive flexibility is and how it develops.  相似文献

Five- and 6-year-olds (N=51) heard stories in which a character sorted items into two locations. Either the character had a false belief about one of the items (e.g., thought a tin contained biscuits, not Lego), or was only partially informed of an item's dual identity (e.g., did not know that a tie was a present). Children found it easier to reject a report of the character's belief that described the true state of affairs when the character had a false belief (e.g., Is Fred's uncle thinking "where shall I put this Lego?"), than to reject one in which an object known to the character was described using a term of which she was ignorant (e.g., Is Mum thinking "where shall I put this present?"). Similarly, children found it easier to predict the character's incorrect sorting of the target items for false belief (with food not toys) than for dual identity (in the wardrobe not with things to take on a visit). Correct reasoning about beliefs and reports of beliefs that misrepresent an object does not imply mastery of the fact that beliefs represent an object in a particular way.  相似文献
