双因子模型假设测验考察一个一般因子和多个组因子,符合很多教育和心理测验的因素结构。“维度缩减”方法将参数估计中多维积分计算化简为多个迭代二维积分,是双因子模型的重要特征。本文针对考察多级评分项目的计算机化自适应测验,首先推导双因子等级反应模型下Fisher信息量的计算,然后推导“维度缩减”方法在项目选择方法中的应用,最后在低、中、高双因子模式题库中比较D-优化方法、后验加权Fisher信息D优化方法(PDO)、后验加权Kullback-Leibler方法(PKL)、连续熵(CEM)和互信息(MI)方法在能力估计的相关、均方根误差、绝对值偏差和欧氏距离的表现。模拟研究表明:(1)双因子模式越强,即一般因子和组因子在项目上的区分度的差异越小,一般因子估计精度降低,组因子估计精度增加,整体能力的估计精度提高;(2)相同实验条件下,连续熵方法的测量精度最高,PKL方法的能力估计精度最低,其它方法的测量精度没有显著差异。 相似文献

The effects of subunit formation on adult listeners' ability to notice changes in a continuous spectral gradient of sound were studied. Results of this experiment support the idea that the auditory system processes information differently within a unit, and that this processing does not occur unless the perceptual system detects unit boundaries. In this experiment, silences were inserted into a continuously changing sound to cause the formation of short units. Listeners noticed the change earlier in conditions with silences inserted than in to conditions where the transition was either unbroken or broken by loud noise bursts. Results are discussed in terms of two processes, one that accentuates stimulus properties present at moments of onset and offset, and a second that uses onsets and offsets to signal the beginnings and ends of units and reduces the change perceived within units. 相似文献

Can exposure to a cleanliness prime affect moral judgements towards harm reduction strategies (HRS) for individuals with substance use disorders? Our research examined (a) the effect of a cleanliness prime on attitudes towards HRS and (b) whether this effect would be attenuated by a brief educational presentation. Participants were randomly assigned to a priming condition and an educational presentation condition. Results demonstrated that (a) the cleanliness prime did not shift attitudes towards HRS, however, (b) the educational presentations significantly shifted attitudes to be more positive after the Harm Reduction presentation and more negative after the Healthy Living presentation. The literature on priming is mixed and our results support a growing body of research challenging the robustness of cleanliness priming and also demonstrates that brief presentations can change attitudes. Our research has implications for education on the benefits of HRS in reducing disease transmission, refuse in the community, and overdose deaths. 相似文献

Relaxation and cognitive-relaxation interventions were compared to a no treatment control in the treatment of high anger drivers. The cognitive portion of the cognitive-relaxation condition adapted the style of Beck's cognitive therapy, particularly use of Socratic questions and behavioral experiments and tryouts, to driving anger reduction. Both interventions lowered indices of driving anger and hostile and aggressive forms of expressing driving anger and increased adaptive/constructive ways of expressing driving anger. The cognitive-relaxation intervention also lowered the frequency of risky behavior. Both interventions lowered trait anger as well. Limitations and implications for treatment and research were discussed. 相似文献

Caution! Warnings as a Useless Countermeasure to Reduce Overconfidence? An Experimental Evaluation in Light of Enhanced and Dynamic Warning Designs 下载免费PDF全文
People often display excessive overconfidence when providing interval estimates, which biases decision‐making. Research has investigated the various measures to effectively reduce overconfidence, and the use of warnings has subsequently been considered to have a negligible reduction effect. We demonstrate with two separate experiments that the impact of warnings has to be reviewed in light of dynamic warning designs and cognitive warning process models. In experiment 1, in contrast to previous studies that only used unstructured warnings, we implement a warning incorporating some core elements of a structured warning design based on research in the fields of human factors and ergonomics. Furthermore, accounting for recent developments in the warning literature, we distinguish between static and dynamic warning design. In experiment 2, we examine the effectiveness of different elements of dynamic warnings. We show that a significantly higher reduction of overconfidence can be achieved by combining a structured warning content with a dynamic stimulus change to increase the warning's noticeability.

The Function of Moods and Emotions: Comment on “Can Sadness Be Good for You? On the Cognitive,Motivational and Interpersonal Benefits of Mild Negative Affect” (Forgas, 2017) 下载免费PDF全文
Romina Palermo 《Australian psychologist》2017,52(1):14-17
Evolutionary theories suggest that all affective states have a function. The fascinating review “Can Sadness Be Good for You? On the Cognitive, Motivational and Interpersonal Benefits of Mild Negative Affect” by Joseph Forgas is a welcome reminder that happiness is not the be all and end all—sadness can also be beneficial. In this commentary, I summarise the studies conducted by Forgas et al. that demonstrate the benefit of mild negative affect for memory, judgement, motivation, and interpersonal behaviour (and those that do not), link them to current theories and models, and discuss avenues for future research. 相似文献
