Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within these relational systems is affected. The current studies test the hypothesis that objects situated in common relational systems come to be perceived as more similar. Similarity increases most for objects playing the same role within a relation (e.g., predator), but also increases for objects playing different roles within the same relation (e.g., the predator or prey role in the hunts relation) regardless of whether the objects participate in the same instance of the relation. This pattern of results can be captured by extending existing models that extract meaning from text corpora so that they are sensitive to the verb-specific thematic roles that objects fill. Alternative explanations based on analogical and inferential processes are also considered, as well as the implications of the current findings to research in language processing, decision making, and category learning. 相似文献

This preliminary study compared brief (1 s) and extended (4 s) wait-time on response opportunities, academic responses, accuracy,
and disruptive behavior of two children with challenging behavior during small group instruction. Brief wait-time increased
children’s response opportunities, academic responses, and accuracy in comparison to extended wait-time. Though variable,
brief wait-time also decreased children’s disruptive behavior. Findings differ from previous research, which found performance
improvements with extended wait-time for children with moderate to profound cognitive disabilities. Limitations of the study
and future research suggestions are discussed. 相似文献

Although religiousness is considered a protective factor against antisocial behaviors and a positive influence on prosocial behaviors, it remains unclear whether these associations are primarily genetically or environmentally mediated. In order to investigate this question, religiousness, antisocial behavior, and altruistic behavior were assessed by self-report in a sample of adult male twins (165 MZ and 100 DZ full pairs, mean age of 33 years). Religiousness, both retrospective and current, was shown to be modestly negatively correlated with antisocial behavior and modestly positively correlated with altruistic behavior. Joint biometric analyses of religiousness and antisocial behavior or altruistic behavior were completed. The relationship between religiousness and antisocial behavior was due to both genetic and shared environmental effects. Altruistic behavior also shared most all of its genetic influence, but only half of its shared environmental influence, with religiousness. 相似文献

We present an interface connecting the ACL2 theorem prover with external deduction tools. The ACL2 logic contains several mechanisms for proof structuring, which are important to the construction of industrial-scale proofs. The complexity induced by these mechanisms makes the design of the interface challenging. We discuss some of the challenges, and develop a precise specification of the requirements on the external tools for a sound connection with ACL2. We also develop constructs within ACL2 to enable the developers of external tools to satisfy our specifications. The interface is available with the ACL2 theorem prover starting from Version 3.2, and we describe several applications of the interface. 相似文献

Abstract : This article addresses the large issue that looms in any Christian engagement with a different faith: the confession of Christ as incarnate God. The manner in which this issue is addressed is by focusing on the difference between Islamic and classical Lutheran understandings of sin. I shall attempt to present the Islamic understanding of sin and articulate how the Islamic understanding of Christ is shaped by its hamartiology. I shall conclude with a few practical suggestions for dialoguing with Muslims on the issue of sin. 相似文献

Computer-simulated microworlds can provide a controlled method for investigating concepts related to naturalistic decision making (NDM). However, the extent to which these tools can be used to generate meaningful outcomes is unknown. The current study used a microworld called Networked Fire Chief (NFC) to explore the range of skills and knowledge acquired as participants gained practice on the program. The complexity of the NFC NDM environment was also explored. Twenty participants each completed 20 equivalent 5-min scenarios on NFC. Interview data, behavioral data and performance scores were collected across the trials. Results confirmed that NFC provides an environment that promotes appropriate perceptual-cognitive processing for NDM. However, performance improved to only a small extent across the 20 trials in four performance areas: speed, accuracy, efficiency and planning. In addition, the number of personal and situational factors to be considered when decision making on NFC was not comparable with real-world NDM environments. Overall, results indicated that the use of microworlds for research should be regulated by an understanding of the limitations of their applicability. 相似文献

Few genetically-informative studies have attempted to explicitly identify the shared environmental (i.e., those environmental influences that contribute to sibling similarity) factors now known to contribute to adolescent delinquency. The current study therefore examined whether the parent-child relationship served as one source of these shared environmental influences. Participants were 610 adoptive and biological families from the Sibling Interaction and Behavior Study (SIBS). Parents and adolescents reported on their parent-child conflict and parental involvement with child, and adolescents reported on their own delinquent behaviors. We employed structural equation modeling and supplementary multilevel modeling, finding consistent evidence that the association between delinquency and the parent-child relationship is at least partially shared environmental in origin. Such findings provide an important extension of previous twin studies, as they suggest that passive genotype-environment correlations do not explain earlier findings of shared environmental influences on this association. 相似文献

Using nonstandard methods, we generalize the notion of an algebraic primitive element to that of an hyperalgebraic primitive element, and show that under mild restrictions, such elements can be found infinitesimally close to any given element of a topological field.Presented by Robert Goldblatt 相似文献
