It is widely accepted that adults show an advantage for deontic over epistemic reasoning. Two published studies (Cummins, 1996b; Harris and Núñez, 1996, Experiment 4) found evidence of this “deontic advantage” in preschool-aged children and are frequently cited as evidence that preschoolers show the same deontic advantage as adults. However, neither study has been replicated, and it is not clear from either study that preschoolers were showing the deontic advantage under the same conditions as adults. The current research investigated these issues. Experiment 1 attempted to replicate both Cummins’s and Harris and Núñez’s studies with 3- and 4-year-olds (N = 56), replicating the former with 4-year-olds and the latter with both 3- and 4-year-olds. Experiment 2 modified Cummins’s task to remove the contextual differences between conditions, making it more similar to adult tasks, finding that 4-year-olds (n = 16) show no evidence of the deontic advantage when no authority figure is present in the deontic condition, whereas both 7-year-olds (n = 16) and adults (n = 28) do. Experiment 3 removed the authority figure from the deontic condition in Harris and Núñez’s task, again finding that 3- and 4-year-olds (N = 28) show no evidence of the deontic advantage under these conditions. These results suggest that for preschoolers, the deontic advantage is reliant on particular contextual cues such as the presence of an authority figure, in the deontic condition. By 7 years of age, however, children are reasoning like adults and show evidence of the advantage when no such contextual cues are present. 相似文献

Several theorists have suggested that impulsivity can be understood as a joint function of the behavioral approach (BAS) and behavioral inhibition systems (BIS). After resolving questions concerning the measurement of impulsivity and BAS, this study examined the relationships among risky health behaviors, impulsivity, BIS, and BAS. Utilizing a sample of undergraduates (N = 904), a structural model was tested in which BAS and BIS predicted impulsivity, which, in turn, predicted risky behavior. Fit indices were acceptable, but not good. A modified version of the model showed a statistically significant negative relationship between BAS and risky behaviors. However, the fit indices were not unequivocally supportive of the need to include that path. Overall, the data suggest that impulsivity is the joint result of countervailing motivational forces and that it partially or fully mediates the influence of BIS and BAS on risky health behavior. 相似文献

The European Clinical Specialization on Fluency Disorders (ECSF) project consists of one-year post-qualification fluency specialization training and a harmonized graduate fluency program. It was developed by eight European universities/colleges to provide the means whereby graduates would meet comparable standards of competence to practice in the field of fluency disorders. In this paper we describe criteria that guided the consortium in their decision making process to create an optimal learning environment for participants. A review of the first completed course cycle, with 23 international participants, is discussed.Educational objectives: After reading this article, the reader will be able to: (1) articulate the rationale for development of the ECSF-course; (2) summarize the content of both the harmonized undergraduate fluency course and the postgraduate fluency specialization course; (3) summarize the benefits of the suggested model for fluency specialization. 相似文献

Research has demonstrated that implicit and explicit evaluations of the same object can diverge. Explanations of such dissociations frequently appeal to dual-process theories, such that implicit evaluations are assumed to reflect object-valence contingencies independent of their perceived validity, whereas explicit evaluations reflect the perceived validity of object-valence contingencies. Although there is evidence supporting these assumptions, it remains unclear if dissociations can arise in situations in which object-valence contingencies are judged to be true or false during the learning of these contingencies. Challenging dual-process accounts that propose a simultaneous operation of two parallel learning mechanisms, results from three experiments showed that the perceived validity of evaluative information about social targets qualified both explicit and implicit evaluations when validity information was available immediately after the encoding of the valence information; however, delaying the presentation of validity information reduced its qualifying impact for implicit, but not explicit, evaluations. 相似文献

Past studies of the determinants of interpersonal trust have focused primarily on how trust forms in isolated dyads. Yet within organizations, trust typically develops between individuals who are embedded in a complex web of existing and potential relationships. In this article, the authors identify 3 alternative ways in which a trustor and trustee may be linked to each other via third parties: network closure (linked via social interactions with third parties), trust transferability (linked via trusted third parties), and structural equivalence (linked via the similarity of their relationships with all potential third parties within the organization). Each of these is argued to influence interpersonal trust via a distinct social mechanism. The authors hypothesized that network closure and structural equivalence would predict interpersonal trust indirectly via their impact on interpersonal organizational citizenship behaviors performed within the interpersonal relationship, whereas trust transferability would predict trust directly. Social network analyses of data gathered from a medium-sized work organization provide substantial support for the hypotheses and also suggest important directions for future research. 相似文献

Young children experience considerable difficulty in learning their first few color terms. One explanation for this difficulty is that initially they lack a conceptual representation of color sufficiently abstract to support word meaning. This hypothesis, that prior to learning color terms children do not represent color as an abstraction, was tested in two experiments using samples of 25- to 39-month-olds and 20- to 32-month-olds. Children's ability to conceptually represent color and their knowledge of color terms were assessed, and a strong association was found between the ability to make inferences based on color and the comprehension of color words. Children who did not comprehend color terms were unsuccessful at a conceptual task that required them to represent color as a property independent of the particular objects that displayed it. The results suggest that the initial absence of an abstract representation of color contributes to the difficulty that young children encounter when first learning color words. 相似文献
