Chinese readers' use of parafoveal character previews was examined. In Experiment 1, the preview of target characters consisted of targets or of graphemically similar, homophonic, or dissimilar characters. Each preview was replaced with the corresponding target when the eyes reached the target location. Oculomotor measures revealed preview benefits for targets, for graphemically similar characters, and for homophonic characters. Experiment 2 showed that parafoveal preview of graphemically similar characters yielded benefits primarily when they shared the phonetic radical with their targets. The phonological relationship between previewed radicals and subsequently viewed targets was ineffective. Chinese character processing thus involves the initial use of orthographic information from the phonetic radical and the activation of the character's phonological form. 相似文献

Advances in understanding the genetics and pathogenesis of disease and in prenatal diagnosis have lead to an exploration of ways to intervene earlier and earlier in the disease process. The possibility of prenatal gene therapy for severe genetic and developmental disorders has sparked new research and debate as to its feasibility, reliability, and ethics as a therapeutic option. Recent animal studies have demonstrated the feasibility of introducing a vector into the developing fetus. The optimal timing and best mode of delivery, however, have yet to be defined. Whether or not this research should be pursued also has been the subject of recent bioethical debates. There is additional concern with the possibility of in utero gene transfer inducing mutagenesis and subsequent tumor formation. This review will provide a summary of the current state of knowledge in the field of prenatal gene therapy and possible directions for the future research. 相似文献

According to the Dogmatism Puzzle presented by Gilbert Harman, knowledge induces dogmatism because, if one knows that p, one knows that any evidence against p is misleading and therefore one can ignore it when gaining the evidence in the future. I try to offer a new solution to the puzzle by explaining why the principle is false that evidence known to be misleading can be ignored. I argue that knowing that some evidence is misleading doesn't always damage the credential of the evidence, and therefore it doesn't always entitle one to ignore it. I also explain in what kind of cases and to what degree such knowledge allows one to ignore evidence. Hopefully, through the discussion, we can not only understand better where the dogmatism puzzle goes wrong, but also understand better in what sense rational believers should rely on their evidence and when they can ignore it. 相似文献

In order to look more closely at the many particular skills examinees utilize to answer items, cognitive diagnosis models have received much attention, and perhaps are preferable to item response models that ordinarily involve just one or a few broadly defined skills, when the objective is to hasten learning. If these fine‐grained skills can be identified, a sharpened focus on learning and remediation can be achieved. The focus here is on how to detect when learning has taken place for a particular attribute and efficiently guide a student through a sequence of items to ultimately attain mastery of all attributes while administering as few items as possible. This can be seen as a problem in sequential change‐point detection for which there is a long history and a well‐developed literature. Though some ad hoc rules for determining learning may be used, such as stopping after M consecutive items have been successfully answered, more efficient methods that are optimal under various conditions are available. The CUSUM, Shiryaev–Roberts and Shiryaev procedures can dramatically reduce the time required to detect learning while maintaining rigorous Type I error control, and they are studied in this context through simulation. Future directions for modelling and detection of learning are discussed. 相似文献

A Monte Carlo study was used to compare four approaches to growth curve analysis of subjects assessed repeatedly with the same set of dichotomous items: A two‐step procedure first estimating latent trait measures using MULTILOG and then using a hierarchical linear model to examine the changing trajectories with the estimated abilities as the outcome variable; a structural equation model using modified weighted least squares (WLSMV) estimation; and two approaches in the framework of multilevel item response models, including a hierarchical generalized linear model using Laplace estimation, and Bayesian analysis using Markov chain Monte Carlo (MCMC). These four methods have similar power in detecting the average linear slope across time. MCMC and Laplace estimates perform relatively better on the bias of the average linear slope and corresponding standard error, as well as the item location parameters. For the variance of the random intercept, and the covariance between the random intercept and slope, all estimates are biased in most conditions. For the random slope variance, only Laplace estimates are unbiased when there are eight time points. 相似文献

Cronbach's alpha系数作为信度估计指标存在诸多弊端.为了克服其不足,研究者提出了多种信度估计,而流行的统计软件尚未直接提供这些参数,以致在实践中并未被广泛采用.为了缩小理论和实践的差距,文章通过具体实例给出几种常用的信度估计(合成信度,单个指标信度和ωh)的Mplus程序. 相似文献

内隐社会认知视野中的攻击性 总被引:5,自引:0,他引:5
本文从内隐社会认知的角度对人类的攻击性进行了探讨,认为人类的攻击性更具内隐性,对人们的影响是以一种自动化的方式进行的,而且认为欲求对攻击性进行量化研究最佳方式是间接测量。本文还对研究攻击性的内隐社会认知方法进行了简单介绍,并指出了从内隐社会认知角度研究攻击性的重要意义。 相似文献

In the process of criticism on political economics,Marx critically drew reasonable factors from positivism arisen at that time,so he can use empirical approach felicitously in the political economic research.Meanwhile,he can correctly use normative method because he transcended the limitations of positivism,and made it a complement to empirical approach.Marx’s critiques of political economy made normative method and empirical approach interdependence and become the methods as a subsystem in the political-ec... 相似文献
