Knowledge Acquisition and Conceptual Change 总被引:3,自引:0,他引:3
Stella Vosniadou 《Psychologie appliquee》1992,41(4):347-357
Dans cet article, je soutiens qu'il est fructueux de penser les réseaux conceptuels en termes de théorie et les processus d'acquisition des connaissances en termes d'articulation ou de restructuration de ces théories. La recherche que mes collègues et moi-même avons entreprise montre que la restructuration d'une connaissance antérieure se fait habituellement lentement et graduellement et qu'elle implique la réinterprétation de certaines croyances que les individus élaborent à partir de leur expérience quotidienne. Pour aider à la restructuration, une formation devrait faire prendre conscience aux étudiants de leurs convictions préétablies et leur proposer un cadre de référence différent en remplacement du celui qu'ils ont construit à partir de leur expérience personnelle.
In this paper I argue that it makes sense to think of conceptual structures as theories, and of the process of knowledge acquisition as the articulation or restructuring of these theories. The research that my colleagues and I have undertaken shows that the restructuring of prior knowledge is usually achieved in a slow and gradual fashion, and that it requires the reinterpretation of certain beliefs, which individuals construct on the basis of their everyday experience. In order to promote restructuring, instruction should aim at making students aware of their entrenched beliefs and at providing them with a different explanatory framework to replace the one they have constructed on the basis of their phenomenal experience. 相似文献

Instruction in baby massage and the Burleigh Relaxation Bath technique was given to one-half of our sample of 32 couples who had just had their first child. This brief intervention, given at 4 weeks post-partum, led to beneficial behavioural and psychological effects for the family system when assessed at 12 weeks postpartum. Depression and marital satisfaction were assessed with mothers and fathers at 4 weeks and 12 weeks after the birth of their child, and self-esteem was measured at 12 weeks only. The mothers and fathers who were shown baby bathing and massage techniques showed higher degrees of marital satisfaction and self-esteem, as well as lower levels of depression at 12 weeks post-partum, than parents who did not receive instruction. It seems likely that brief interventions which educate new parents concerning functional techniques of baby care may favourably affect their feelings of competence and be of benefit to the entire family system. 相似文献

In the various models of family therapy, family systems are described as being patterned and programmed in their operations and development. The regularities and patterns found in family life are believed to be the expression of a program that determines the behavior of the family system and each of its members. Therapists holding this view will use "programming methods" in order to map family phenomena, and therapeutic work will consist of disrupting the problematic sequences in a deterministic way. However, if we take into consideration the impossibility of always linking inputs and outputs and the inability to evaluate consistently the behaviors in a system, problems associated with indeterminancy appear. Under such conditions, it may be impossible for therapists to formulate programs of family functioning. Therefore, we have operationalized a set of methodological principles that can be applied in such conditions. In this article we present the theoretical and practical implications for the field of therapy of "nonprogramming methods." A videotaped session is analyzed in order to show the application of the nonprogramming methods in clinical practice. 相似文献

This study reports data on the acquisition of knowledge about astronomy in children from India. Based on prior research, we hypothesized that the cosmological models that children construct are influenced by both first-order and second-order constraints on knowledge acquisition. First-order constraints are the implicit assumptions that govern the construction of initial cosmological models. Examples of such constraints include the assumptions that the earth is flat and supported. Such first-order constraints are presumed to be universal. Second-order constraints arise from the specific properties ascribed to cosmological objects. For example, representations of the earth's shape and location relative to the sun and moon constrain the kinds of mechanisms that are generated to account for the day-night cycle. We hypothesized that in cultures where both folk cosmologies and the scientific cosmological model are accessible to children, aspects of folk models are likely to be incorporated in children's cosmologies if they provide a psychologically easier way of satisfying first-order constraints. This hypothesis is supported by our findings with regard to universality and culture specificity in children's cosmologies. Indian children's cosmologies honor a variety of universal first-order constraints. These include constraints on the shape of the earth (e.g., support and flatness) and on the relative locations and motions of objects in the cosmology (e.g., continuity). However, many Indian children borrow the idea that the earth is supported by an ocean or a body of water from folk cosmology. This solution to the support constraint on the shape of the earth is not found in American children's initial cosmologies. 相似文献

This paper considers some mathematical aspects of minimum trace factor analysis (MTFA). The uniqueness of an optimal point of MTFA is proved and necessary and sufficient conditions for a point x to be optimal are established. Finally, some results about the connection between MTFA and the classical minimum rank factor analysis will be presented. 相似文献

Subjects were timed while they drew inferences from syntactically affirmative and negative sentences containing the semantically positive and negative implicative predicates remember/forget and bother/neglect, under different linguistic contexts that met the presuppositions of the sentences at varying levels of generality. Different patterns of inference latencies were obtained for the two implicative predicates studied, suggesting that there are important differences among semantically negative implicative predicates that influence their representation and processing. Regardless of these differences, inference latencies for all sentences decreased when they were presented in contexts that met some of their presuppositions, indicating that context can facilitate inferential processing. 相似文献
