随着经济生活中的各种冲突竞争日益增多,如何分析这些错综复杂现象,对策论作为一种数学工具对此提供了分析框架。本文结合案例,介绍了两种基本模型:二人零和对策和二人非零和对策,并对这些模型的结构、模型解及其实际背景进行了讨论,指出:(1)与零和对策相比,非零和对策更接近于现实的经济生活;(2)对策论对经济竞争冲突结果的求出,从根本上说是一种概率预示;(3)对策论可以激发人们以一种新的方法思考理解经济生活中的竞争冲突现象。  相似文献

The purpose of this experiment, conducted with second-grade children (mean age: 7;8), was to examine the hypothesis that less skilled comprehenders in a reading situation suffer an impairment in spoken language comprehension and, more specifically, in the on-line processing of anaphoric pronouns. Skilled and less skilled comprehenders performed a cross-modal naming task investigating the effects of pronoun gender and pragmatic inference from the verb on the integration of two successive sentences. Results revealed different patterns of effects in the two groups. The skilled comprehenders integrated on-line sentences by relying on pronoun gender and verb meaning. Pronoun gender appeared to exert a dominant influence relative to verb bias. In the less skilled comprehenders, on-line integration was not systematic, being dependent on the meaning of the verb and the proximity of the referent. Complementary analyses revealed similar patterns of effects among less skilled comprehenders, whether they were good decoders or poor decoders. These results show that less skilled comprehenders are developmentally delayed compared with their skilled peers, and extend the language impairment hypothesis to cover discourse-level processes.  相似文献

The issue of sex differences in reading disability has been of recent interest in relation to sex ratios in families with reading disabled children and to possible sex biases in referred populations. Data from a study of 570 twins are used to develop alternative definitions of reading disability that vary in the manner to which sex effects are taken into account. These definitions include discrepancies between reading quotients and IQ, the use of the regression of reading onto IQ and chronological age/reading age differences. In each case the reading and spelling disability was defined either separately for the sexes or based upon the data for the sexes combined and with and without an IQ>90 exclusion criterion. The consequences of using the alternative definitions for prevalence, sex ratio and heritability are examined. The results demonstrate that the characteristics of reading disabled children vary with the way disability is defined. The excess of males seems to be a robust finding. Definitions that take into account differences in mean score for males and females reduce but do not eradicate the sex ratio. From the genetic analysis, there is no support for the suggestion that the genetic effect on reading is greater for females than males. It is concluded that the use of regression based procedures for identifying reading disability is desirable but that at present there is insufficient evidence to justify the adoption of separate regression procedures for the two sexes.  相似文献

Performance on a standardized reading comprehension test reflects the number of correct answers readers select from a list of alternate choices, but fails to provide information about how readers cope with the various cognitive demands of the task. The aim of this study was to determine whether three groups of readers: normally achieving (NA), poor comprehenders (CD), with no decoding disability, and reading disabled (RD), poor comprehenders with poor decoding skills, differed in their ability to cope with reading comprehension task demands. Three task variables reflected in the question-answer relations that appear on standardized reading comprehension tests were identified.Passage Independent (PI) question can be answered with reasonable accuracy based on the reader's prior knowledge of the passage content.Inference (INFER) questions required the reader to generate an inference at the local or global test level.Locating (LOCAT) questions require the reader to match the correct answer choice to a detail explicitly stated in the text either verbatim or in paraphrase form. The relations among reader characteristics, cognitive task factors and reading comprehension test scores were analyzed using a structural relations equation with LISREL. It was found that the three reading groups differed with respect to the underlying relationship between their performance on specific question-answer types and their standardized reading comprehension score. For the NA group, a high score on PI was likely to be accompanied by a low score on INFER, whereas in the CD and RD groups, PI and INFER are positively related. The finding of a negative relationship between background knowledge and inference task factors for normally achieving readers suggests that even normal readers may have comprehension difficulties that go undetected on the basis of a standardized scores. This study indicates that current comprehension assessments may not be adequate for assessing specific reading difficulties and that more precise diagnostic tools are needed.  相似文献
