Utsumi A 《Cognitive Science》2011,35(2):251-296
Recent metaphor research has revealed that metaphor comprehension involves both categorization and comparison processes. This finding has triggered the following central question: Which property determines the choice between these two processes for metaphor comprehension? Three competing views have been proposed to answer this question: the conventionality view ( Bowdle & Gentner, 2005 ), aptness view ( Glucksberg & Haught, 2006b ), and interpretive diversity view ( Utsumi, 2007 ); these views, respectively, argue that vehicle conventionality, metaphor aptness, and interpretive diversity determine the choice between the categorization and comparison processes. This article attempts to answer the question regarding which views are plausible by using cognitive modeling and computer simulation based on a semantic space model. In the simulation experiment, categorization and comparison processes are modeled in a semantic space constructed by latent semantic analysis. These two models receive word vectors for the constituent words of a metaphor and compute a vector for the metaphorical meaning. The resulting vectors can be evaluated according to the degree to which they mimic the human interpretation of the same metaphor; the maximum likelihood estimation determines which of the two models better explains the human interpretation. The result of the model selection is then predicted by three metaphor properties (i.e., vehicle conventionality, aptness, and interpretive diversity) to test the three views. The simulation experiment for Japanese metaphors demonstrates that both interpretive diversity and vehicle conventionality affect the choice between the two processes. On the other hand, it is found that metaphor aptness does not affect this choice. This result can be treated as computational evidence supporting the interpretive diversity and conventionality views. 相似文献

Forty years after the publication of Beyond Freedom and Dignity (Skinner, 1971) and the continuing growth of behavior analysis, the future of humanity and the role of behavioral science in that future remain uncertain. A recent paper by Chance (2007) documented a shift in Skinner's views during the last years of his life. Skinner had long advocated a science and technology of behavior for finding and engineering solutions to cultural and global problems and advancing human development. This optimism had given way under a gradual realization that the science of behavior was in fact showing how such problems were unlikely to be solved in time to avert a variety of possible disasters. Chance described nine behavioral phenomena that appear to interfere with effective problem-solving behavior on a large scale and in effective time frames. These phenomena are reviewed toward an analysis of common themes. Research is also reviewed that involves nonverbal, verbal, and cultural contingencies that may lead to applications designed to address the common themes. Problems and strategies of implementation are also discussed. The challenges are daunting, but may nevertheless be regarded as technical problems best suited for a science and technology of behavior. 相似文献

In recent years, operant discrimination training procedures have been used to teach giant African pouched rats to detect tuberculosis (TB) in human sputum samples. This article summarizes how the rats are trained and used operationally, as well as their performance in studies published to date. Available data suggest that pouched rats, which can evaluate many samples quickly, are sufficiently accurate in detecting TB to merit further investigation as a diagnostic tool. 相似文献

Mintz (2003) found that in English child-directed speech, frequently occurring frames formed by linking the preceding (A) and succeeding (B) word (A_x_B) could accurately predict the syntactic category of the intervening word (x). This has been successfully extended to French (Chemla, Mintz, Bernal, & Christophe, 2009). In this paper, we show that, as for Dutch (Erkelens, 2009), frequent frames in German do not enable such accurate lexical categorization. This can be explained by the characteristics of German including a less restricted word order compared to English or French and the frequent use of some forms as both determiner and pronoun in colloquial German. Finally, we explore the relationship between the accuracy of frames and their potential utility and find that even some of those frames showing high token-based accuracy are of limited value because they are in fact set phrases with little or no variability in the slot position. 相似文献

为探讨单病种平均住院日的影响因素,采用多元逐步回归分析,对住院构成前5位病种的平均住院日影响因素进行分析。结果显示,有10个影响因素进入回归方程,不同病种平均住院日影响因素略有不同,是否转科对平均住院日影响最大。在医院管理过程中,需不断加强医院流程管理与改造,实施临床路径,合理制定医院平均住院日指标。 相似文献
