Relations between interior self‐knowledge and (a) imaginary companion (IC) status and (b) theory of mind (ToM) abilities were investigated in a sample (N= 80) of 4‐ to 7‐year‐olds. Interior self‐knowledge was assessed in terms of the extent to which children acknowledged that they (rather than an adult) were the authority on unobservable aspects of themselves (e.g., dreaming, thinking, hunger). Compared with children without an IC, those who possessed a parentally corroborated IC ascribed less interior self‐knowledge to an adult, with a trend for them to assign more interior self‐knowledge to themselves. Children's interior self‐knowledge judgments were not associated with their ToM performance. IC status was also unrelated to ToM performance. We consider how having an IC may provide children with opportunities to distinguish between knowledge that is inaccessible to an external observer and that which an external observer may glean without being told. 相似文献

Theories of skill acquisition have made radically different predictions about the role of general problem-solving methods in acquiring rules that promote effective transfer to new problems. Under one view, methods that focus on reaching specific goals, such as means-ends analysis, are assumed to provide the basis for efficient knowledge compilation (Anderson, 1987), whereas under an alternative view such methods are believed to disrupt rule induction (Sweller, 1988). We suggest that the role of general methods in learning varies with both the specificity of the problem solver's goal and the systematicity of the strategies used for testing hypotheses about rules. In the absence of a specific goal people are more likely to use a rule-induction learning strategy, whereas provision of a specific goal fosters use of difference reduction, which tends to be a non-rule-induction strategy. We performed two experiments to investigate the impact of goal specificity and systematicity of rule-induction strategies in learning and transfer within a complex dynamic system. The results of Experiment 1 indicated that during free exploration of a problem space, greater learning occurred if participants adopted more systematic strategies for rule induction, and that participants come to favor such strategies. Experiment 2 revealed that participants who were provided with a specific goal performed well on the initial problem but were impaired on a transfer test using a similar problem with a different goal. Instruction on a systematic rule-induction strategy facilitated solution for both the initial and transfer problems, but participants' use of this strategy declined if they had a specific goal. Our results support Sweller's (1988) proposal that general problemsolving methods applied to a specific goal foster acquisition of knowledge about an isolated solution path but do not provide an effective way of learning the overall structure of a problem space. We interpret these results in terms of dualspace theories of search through problem space. 相似文献

This study used the interpersonal–psychological theory of suicide to explore the relationships among DSM-5 posttraumatic stress disorder (PTSD) symptom clusters derived from the six-factor anhedonia model and facets of acquired capability for suicide (ACS). In a sample of 373 trauma-exposed undergraduates, most PTSD symptom clusters were negatively associated with facets of ACS in bivariate correlations, but the anhedonia cluster was positively associated with ACS in regression models. Structure coefficients and commonality analysis indicated that anhedonia served as a suppressor variable for the other symptom clusters. Our findings further elucidate the complex relationship between specific PTSD symptom clusters and ACS. 相似文献

This paper examines some of the contemporary cultural practices associated with the traditional festival of Halloween as it is celebrated by children in Britain and the United States. Using ethnographic evidence from a variety of sources, the authors seek to explore the range of activities which constitute the modern Halloween, particularly as it is mediated to children through the forms of consumer culture. The paper analyses the changing social, historical and religious patterns which have displaced the celebration of Halloween onto children, and offers an account of them which points to the persistence of a coherent spirituality—what the authors term a ‘spirituality of boundaries‘—to be found in the symbolism of the festival and its interaction with the lives and representation of children. 相似文献
