青少年恋爱关系：研究取向、方法与影响因素

青少年恋爱关系是在性吸引基础上建立起来的一种相互认可的、至少持续一段时间的强烈的情感联系和互动关系, 其研究取向主要有生物社会取向、认知表征取向和发展背景取向, 研究方法主要包括自我报告法、观察法和录像回顾法。影响青少年恋爱关系的有个体因素、人际关系因素和社会因素, 未来可在理论的整合、关系品质的稳定性及微观背景作用的机制、样本的代表性等方面进一步研究。     

发展心理学研究中个体定向的理论与方法

长期以来, 发展心理学研究主要采取变量定向的方法。近年来, 随着发展心理学理论的发展和人类发展个体差异的科学事实的积累, 个体定向的方法得以发展并且成为发展心理学研究的主要方法思路之一。个体定向的方法关注作为整体的个体, 旨在确定有意义的同质性个体类别或亚组。个体定向的方法包括一系列的基本理论原则, 具体数据分析方法包括传统聚类分析、基于模型的聚类方法以及配置频次分析等。发展心理学研究需综合运用个体定向的方法与变量定向的方法。     

情绪调节策略对日常生活事件与情绪体验关系影响的多层分析

运用经验抽样法对154名大学生的日常情绪体验、生活事件进行为期14天的追踪调查,通过多层线性模型（HLM）探讨日常生活事件与情绪体验的关系及情绪调节策略对二者关系的影响。结果表明：大学生积极情绪体验多于消极情绪体验。在个体内和个体间水平,消极事件都对积极情绪有显著的负向预测作用,对消极情绪有显著的正向预测作用;积极事件对积极情绪有显著的正向预测作用。积极事件对消极情绪的负向预测作用只在个体间水平显著。表达抑制这种情绪调节策略能够增强消极生活事件与消极情绪体验的关系。     

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     

认知诊断计算机自适应测验中平衡属性收敛的新方法

提出两种认知诊断计算机自适应测验下平衡属性收敛的新方法（MABI、RTA）,模拟研究系统探讨和比较了此二者与已有方法（ABI、IABI和RABI）的表现。结果发现：（1）新方法较不考虑属性收敛的方法有更高的准确率以及更均衡的题目使用率;（2）新方法较ABI和RABI有稍低的准确性,但有更平衡的题目使用率;（3）新方法与IABI的准确性和题目使用率在不同选题策略下各有合优势。总之,两种新方法较好地兼顾测量准确性、题目使用率以及题库曝光情况。     

物理概念图试题的评分方法

详细介绍了运用知识编码对物理概念图试题进行评分的具体方法,并对物理概念图试题的难度、区分度、信度和效度进行了检验,计算了物理概念图试题与传统物理题型共同组成的期末物理测验的信度,说明依据知识编码评定物理概念图试题分数,是一种行之有效的评分方法,按照知识编码评定物理概念图试题的分数使物理概念图试题成为一道高质量的试题。     

结合题目作答时间的计算机化自适应测验选题方法

计算机形式的测验能够记录考生在测验中的题目作答时间（Response Time, RT），作为一种重要的辅助信息来源，RT对于测验开发和管理具有重要的价值，特别是在计算机化自适应测验（Computerized Adaptive Testing, CAT）领域。本文简要介绍了RT在CAT选题方面应用并作以简评，分析了这些技术在实践中的可行性。最后，探讨了当前RT应用于CAT选题存在的问题以及可以进一步开展的研究方向。     

Application of a worry reduction intervention in a medically unexplained symptoms-analogue student-sample

Objective: Worry is an important perpetuating factor of Medically Unexplained Symptoms (MUS). Former research has shown that a worry postponement instruction is effective in reducing Subjective Health Complaints (SHC) in non-clinical samples. This study aimed to (1) replicate these findings in a MUS-analogue student-sample and (2) assess alexithymia as a moderator.

Design: The current study had an experimental design with two waves of data collection: pre- and post-intervention.

Main outcome measures: A MUS-analogue student-sample consisting of 114 undergraduate students with high self-reported health worry and a minimum of two doctor visits in the previous year with no current diagnosis for a (chronic or acute) disease were instructed to register their worry frequency and duration eight times per day via an experience sampling-application on their smartphones. The intervention group additionally postponed their worries to a 30-minute period in the evening. SHC were assessed pre- and post-intervention.

Results: The intervention did not have an effect on worry or SHC. Alexithymia did not moderate this effect (p’s > .05).

Conclusion: Our study did not find evidence for the effectiveness of the worry reduction intervention on SHC in a MUS-analogue student-sample. This finding contributes to several previous studies that have found mixed evidence for the effectiveness of the worry reduction intervention on SHC and suggests that the worry intervention may not be effective in all cases.     

Simulation and multi‐attribute utility modelling of life cycle profit

Investments on capital goods are assessed with respect to the life cycle profit as well as the economic lifetime of the investment. The outcome of an investment with respect to these economic criteria is generally non‐deterministic. An assessment of different investment options thus requires probabilistic modelling to explicitly account for the uncertainties. A process for the assessment of life cycle profit and the evaluation of the adequacy of the assessment is developed. The primary goal of the assessment process is to aid the decision‐maker in structuring and quantifying investment decision problems characterized by multiple criteria and uncertainty. The adequacy of the assessment process can be evaluated by probabilistic criteria indicating the degree of uncertainty in the assessment. Bayesian inference is used to re‐evaluate the initial assessment, as evidence of the system performance becomes available. Thus authentication of contracts of guarantee is supported. Numerical examples are given to demonstrate features of the described life cycle profit assessment process. Copyright © 2001 John Wiley & Sons, Ltd.
