基于CAT的在线标定:设计与方法

项目增补是题库建设和维护的重要手段, 而标定新题参数是项目增补的重要内容。在线标定设计和在线标定方法分别研究新题的施测方式和参数估计方法, 是计算机化自适应测验(computerized adaptive testing, CAT)情景下项目增补的核心技术。重点厘清在线标定设计与在线标定方法的发展思路和脉络, 并对它们的特点、联系和表现进行介绍和评价。未来应基于其他信息指标进一步研究在线标定设计, 可基于联合估计和误差校正的思路探究在线标定方法, 应加强研究认知诊断CAT和多维CAT的在线标定技术, 深入开展项目增补方法的实证研究。     

Using dual-criteria methods to supplement visual inspection: Replication and extension

The dual-criteria and conservative dual-criteria methods effectively supplement visual analysis with both simulated and published datasets. However, extant research evaluating the probability of observing false positive outcomes with published data may be affected by case selection bias and publication bias. Thus, the probability of obtaining false positive outcomes using these methods with data collected in the course of clinical care is unknown. We extracted baseline data from clinical datasets using a consecutive controlled case-series design and calculated the proportion of false positive outcomes for baseline phases of various lengths. Results replicated previous findings from Lanovaz, Huxley, and Dufour (2017), as the proportion of false positive outcomes generally decreased as the number of points in Phase B (but not Phase A) increased using both methods. Extending these findings, results also revealed differences in the rate of false positive outcomes across different types of baselines.     

An interactive procedure for learning about preferences: Case study of a portfolio manager

This paper presents a new interactive procedure for learning and interpreting the choices available to a decision maker confronted with a discrete decision problem. The procedure guides a decision maker through the evaluation process, has an ability ‘to learn’ from previous choices and generates a set of rules that describe a decision maker's posterior preferences. The validity of the procedure was tested by creating an investment portfolio. The emphasis of the application is on assisting the portfolio manager to determine the decision consistency of a given portfolio selection process.     

第二语言阅读中的元认知

在第二语言习得领域,元认知自20世纪90年代中后期开始引起了研究者的关注并逐渐被应用于阅读、写作、听力和口语等各种教学实践中。该文以元认知结构的二分法为框架,说明了心理学研究者致力于探讨第二语言学习者通过元认知监控来使用元认知知识的内部加工过程的特点,并从影响第二语言阅读的自我观念、文本内容和策略使用意识等方面系统介绍了元认知知识、监控与第二语言阅读的关系,最后对元认知的研究方法进行了归纳和展望

Theology: Reduction or Autonomy?

Issues of the nature and task of theology remain important to the science-theology dialogue. This paper lays out a framework for understanding the nature of theology in relation to the other sciences. In particular, I argue that the primary question remains one of autonomy and reduction. If theology is a genuine academic discipline, then it should be an autonomous field with its own subject matter and norms. Wolfhart Pannenberg argues that theology is the science of God, but I suggest that theology be more broadly understood as the science of meaning. If we recognize this, the modes of interaction between theology and the other sciences becomes clearer.     

反应时技术在品牌联想测查中的应用

反应时技术在以往品牌研究中主要被用来测查品牌名称与产品类别的联系强度。基于品牌名称语义网络的构成,在已有研究的启发下,将反应时测量技术应用于品牌联想结构的测查之中。研究采用了反应时方法和传统的自由联想方法对三个产品种类五个品牌的品牌联想结构进行了探索。两种结果的对比分析验证了反应时方法的可行性,并且在测量的精确性与客观性上,反应时方法具有较大的优势。该测量技术提供的客观量化数据有助于揭示消费者内在的品牌联想结构,在市场研究中具有广泛的应用前景。     

Heymans' temperamental dimensions in personality research

In this article an overview is given of personality research related to the temperamental system of the Dutch philosopher and psychologist Gerard Heymans (1852–1930). After a sketch of this three-dimensional typology, three domains of research are briefly described. The first is a line of research on the system itself and its applications in differential psychology. In the second, the role of its dimensions in modern trait psychology is sketched. In the third line of thought the Heymans categories are viewed and investigated as dimensions of person perception.     

A developmental study of learning disabilities and memory

Seven-, ten-, and thirteen-year-old learning-disabled (LD) and non-learning-disabled (NORM) children were presented specially structured lists of 38 words each and tested for free recall. Each list contained only four semantically related words. Two of the four related words were presented contiguously (serial positions 9 and 10) and the other two words were spaced (serial positions 20 and 30). All children recalled disproportionately more adjacent words (item 9 or 10) than any other words. Spaced words (items 20 and 30) were less likely to be recalled by the younger children than by the older children and by the LDs than by the NORMS. These findings provided support for the distinction between automatic and purposive semantic processing. NORMs' recall was governed by purposive semantic processing to a greater extent than was LDs' recall. However, no group or age differences were observed in automatic semantic processing.     

Inferential theory for partially disattenuated correlation coefficients

Four measurement designs are presented for use with correlation coefficients corrected, in one variable, for attenuation due to unreliability—coefficients that we term partially disattenuated correlation coefficients. Asymptotic expressions are derived for the variances and covariances of the estimates accompanying each design. Empirical simulation results that bear on the preceding mathematical developments are then presented. In addition to providing insights into the distributions of the estimates, the empirical results demonstrate satisfactory Type I error control for typical inferential applications. Power is shown to be equal to or greater than that of corresponding product-moment correlations in three of the four designs. Implications for practice are discussed.Support for the research reported in this article was provided by the Natural Sciences and Engineering Research Council of Canada.
