Effects of Discontinue Rules on Psychometric Properties of Test Scores

This paper provides results on a form of adaptive testing that is used frequently in intelligence testing. In these tests, items are presented in order of increasing difficulty. The presentation of items is adaptive in the sense that a session is discontinued once a test taker produces a certain number of incorrect responses in sequence, with subsequent (not observed) responses commonly scored as wrong. The Stanford-Binet Intelligence Scales (SB5; Riverside Publishing Company, 2003) and the Kaufman Assessment Battery for Children (KABC-II; Kaufman and Kaufman, 2004), the Kaufman Adolescent and Adult Intelligence Test (Kaufman and Kaufman 2014) and the Universal Nonverbal Intelligence Test (2nd ed.) (Bracken and McCallum 2015) are some of the many examples using this rule. He and Wolfe (Educ Psychol Meas 72(5):808–826, 2012. https://doi.org/10.1177/0013164412441937) compared different ability estimation methods in a simulation study for this discontinue rule adaptation of test length. However, there has been no study, to our knowledge, of the underlying distributional properties based on analytic arguments drawing on probability theory, of what these authors call stochastic censoring of responses. The study results obtained by He and Wolfe (Educ Psychol Meas 72(5):808–826, 2012. https://doi.org/10.1177/0013164412441937) agree with results presented by DeAyala et al. (J Educ Meas 38:213–234, 2001) as well as Rose et al. (Modeling non-ignorable missing data with item response theory (IRT; ETS RR-10-11), Educational Testing Service, Princeton, 2010) and Rose et al. (Psychometrika 82:795–819, 2017. https://doi.org/10.1007/s11336-016-9544-7) in that ability estimates are biased most when scoring the not observed responses as wrong. This scoring is used operationally, so more research is needed in order to improve practice in this field. The paper extends existing research on adaptivity by discontinue rules in intelligence tests in multiple ways: First, an analytical study of the distributional properties of discontinue rule scored items is presented. Second, a simulation is presented that includes additional scoring rules and uses ability estimators that may be suitable to reduce bias for discontinue rule scored intelligence tests.

     

不同色光照明后相同白光色貌的色位移—相继颜色对比

本实验采用双眼匹配法,测试了人眼经受不同色光照明后颜色视觉的变化。测量了它们的色位移并表示在国际照明学会(CIE)1931年色度图上。实验发现,与适应色类同的色光会引起相同的白光色貌。此外还表明,对色光适应的人眼会把白光看成该适应色的补色。这些结果为我们进一步理解视觉过程提供线索。     

Different Effects of Cognitive Shifting and Intelligence on Creativity

The relationship between creativity and executive control has long been controversial. Some researchers view creative thinking as a defocused process with little executive control involvement, whereas others claim that executive control plays a vital role in creative thinking. In this study, we focused on one subcomponent of executive control, cognitive shifting, and examined its relationship with creativity by using latent variable analysis and structural equation modeling. We also analyzed whether this relation was mediated by intelligence. The results showed that: (a) cognitive shifting ability had a positive relationship with creativity, but only on the quantitative aspects (fluency and flexibility); (b) Intelligence had a positive relationship with both quantitative and qualitative aspects (originality) of creativity, and its effect on qualitative aspect was stronger than that on the quantitative aspect; (c) There was a mediating effect of intelligence on the relationship between creativity cognitive and shifting.     

Bimanual Lifting: Do Fingertip Forces Work Independently or Interactively?

Bimanual coordination is a commonplace activity, but the consequences of using both hands simultaneously are not well understood. The authors examined fingertip forces across 4 experiments in which participants undertook a range of bimanual tasks. They first measured fingertip forces during simultaneous lifts of 2 identical objects, noting that individuals held the objects with more force bimanually than unimanually. They then varied the mass of the objects held by each hand, noting that when both hands lifted together performance was equivalent to unimanual lifts. The authors next measured one hand's static grip force while the other hand lifted an object. They found a gradual reduction of grip force throughout the trial, but once again no evidence of one hand influencing the other. In the final experiment the authors tested whether tapping with one hand could influence the static grip force of its counterpart. Although the authors found no changes in static grip force as a direct consequence of the other hand's actions, they found clear differences from one task to the other, suggesting an effect of task instruction. Overall, these results suggest that fingertip forces are largely independent between hands in a bimanual lifting context, but are sensitive to different task requirements.     

基于印象管理量表的反应模式筛查故意作假者

社会称许性反应由两个成分组成:自我欺骗(无意识地夸大反应)和印象管理(有意识地歪曲作答)。采用实验研究范式和Mixed Rasch Model,探讨二者在BIDR印象管理量表上的得分及作答模式差异。结果发现,当发生印象管理时,量表分数高于仅发生自我欺骗时的分数,且被试倾向选择极端反应。进而采用logistic回归对量表分数划定分界线,将高于分数线的被试认定为故意作假者,低于分界线的被试认定为仅发生了自我欺骗,没有故意作假。     

高职生时间管理倾向与成就动机的关系研究

文章采用《青少年时间管理倾向量表》和《成就动机量表》对贵州省3个高职院校577名学生进行了问卷调查,结果发现,高职男生在时间效能感、时间价值感和时间监控观上显著高于女生;高职生的时间管理倾向与成就动机存在显著相关,其中高职生的时间管理倾向各维度与追求成功的动机存在显著的正相关,与避免失败的动机存在显著的负相关;高职生的高时间管理组在追求成功的动机上显著高于低时间管理组,而在避免失败的动机上低于低时间管理组;时间价值感、时间监控观对追求成功的动机具有显著的预测力,时间价值感、时间监控观和时间效能感对避免失败的动机具有显著的影响力。     

Family Protection and Prevention of Alcohol Use Among Hispanic Youth at High Risk

Research regarding prevention strategies for Hispanic youth stress the importance of family interventions because of the particular importance of family as a protective factor within the Hispanic community. Starting in 1995, the Center for Substance Abuse Prevention conducted the National Cross-Site Evaluation of High Risk Youth Programs, a 5-year drug and alcohol prevention study with a sample of approximately 10,500 youth, including nearly 3,000 Hispanic youth. Youth were surveyed regarding their alcohol use patterns and risk and protective factors, with several measures of family relationships, including family connectedness, family supervision, and parental attitudes toward their child's alcohol use. Analyses indicate that family factors are highly linked to alcohol use among Hispanics, particularly among Hispanic females. Longitudinal growth curve analyses indicate that improving the connections that young Hispanic females have to their parents can have positive long-term effects on delaying or reducing their alcohol use. This evaluation was conducted under the direction of Dr. Soledad Sambrano, Ph.D. of the Center for Substance Abuse Prevention under contract #2777-95-5002 with EMT Associates, Inc. and ORC Macro. The views expressed herein represent the opinions and analyses of the individual authors and may not necessarily reflect the opinions, official policy, or position of the U.S. Department of Health and Human Services, the Public Health Service, the Substance Abuse and Mental Health Service Administration, or the Center for Substance Abuse Prevention.     

"Proper" Binormal ROC Curves: Theory and Maximum-Likelihood Estimation

The conventional binormal model, which assumes that a pair of latent normal decision-variable distributions underlies ROC data, has been used successfully for many years to fit smooth ROC curves. However, if the conventional binormal model is used for small data sets or ordinal-category data with poorly allocated category boundaries, a "hook" in the fitted ROC may be evident near the upper-right or lower-left corner of the unit square. To overcome this curve-fitting artifact, we developed a "proper" binormal model and a new algorithm for maximum-likelihood (ML) estimation of the corresponding ROC curves. Extensive simulation studies have shown the algorithm to be highly reliable. ML estimates of the proper and conventional binormal ROC curves are virtually identical when the conventional binormal ROC shows no "hook," but the proper binormal curves have monotonic slope for all data sets, including those for which the conventional model produces degenerate fits.

合体汉字字形识别过程探索

该研究用微观发生范式探索了合体汉字和假字的字形识别过程 ,结果发现 :(1 )部件字、真字和假字的正确提取率随呈现时间增长而提高 ,字形刺激的特征加工是一个有序的发展过程 ,对字形的识别加工过程受字形熟悉性和字形结构方式的影响 ;(2 )在左右型字刺激和上下型字刺激中 ,经常首先从右部件或下部件中提取笔画或笔画组合 (称首特征 ) ,而且首特征的提取不受字形熟悉性影响。根据以上结果可以推测 ,字形结构属性在字形识别加工的最初阶段先于特征获加工 ,字形熟悉性则对首特征提取后的特征或部件加工过程产生影响。
