A COMPARISON OF SENSORY INTEGRATIVE AND BEHAVIORAL THERAPIES AS TREATMENT FOR PEDIATRIC FEEDING DISORDERS

We compared the effects of escape extinction (EE) plus noncontingent reinforcement (NCR) with sensory integration therapy as treatment for the feeding problems of 2 children. Results indicated that EE plus NCR was more effective in increasing acceptance, decreasing inappropriate behavior, and increasing amount consumed relative to sensory integration for both children. The results are discussed in terms of the challenges of evaluating sensory‐integration‐based treatments, and the reasons why component analyses of multicomponent treatments like sensory integration are important.     

Dominance Measuring Method Performance under Incomplete Information about Weights

In multi‐attribute utility theory, it is often not easy to elicit precise values for the scaling weights representing the relative importance of criteria. A very widespread approach is to gather incomplete information. A recent approach for dealing with such situations is to use information about each alternative's intensity of dominance, known as dominance measuring methods. Different dominance measuring methods have been proposed, and simulation studies have been carried out to compare these methods with each other and with other approaches but only when ordinal information about weights is available. In this paper, we use Monte Carlo simulation techniques to analyse the performance of and adapt such methods to deal with weight intervals, weights fitting independent normal probability distributions or weights represented by fuzzy numbers. Moreover, dominance measuring method performance is also compared with a widely used methodology dealing with incomplete information on weights, the stochastic multicriteria acceptability analysis (SMAA). SMAA is based on exploring the weight space to describe the evaluations that would make each alternative the preferred one. Copyright © 2012 John Wiley & Sons, Ltd.     

基于面孔的印象形成:神经科学的视角

印象形成过程是心理学的经典研究主题,最近随着神经科学的兴起和脑成像技术的成熟,研究者开始从神经科学的角度审视人类的印象形成过程.印象形成主要基于三种信息,即面孔知觉,直接互动和二手信息.就面孔而言,基于面孔的印象形成更为快速和准确,其中杏仁核在其中起着重要的作用;作为对照,文章简要介绍了基于二手信息和直接互动的印象形成,它们更多涉及深思熟虑的任务,激活内侧前额皮层和颞上沟后端.印象形成的神经机制,线索之间的关系、印象形成的影响伴随着新技术的运用将会得到研究者的关注.     

时距加工的记忆负荷效应

为了探索非时间任务短时记忆加工对不同长度时距加工的影响是否一致,本研究采用双任务范式,操纵时距编码阶段的短时记忆加工负荷,以平均复制时距为因变量指标,考察了非时间任务短时记忆加工对1-6秒时距加工的影响。结果发现,1秒、2秒及3秒的平均复制长度不随记忆负荷的大小而变化,4秒、5秒及6秒的平均复制长度随着记忆负荷变大而缩短。这意味着非时间短时记忆对时距加工影响具有选择性。     

The Challenges of Qualitatively Coding Ancient Texts

We respond to several important and valid concerns about our study (“The Prevalence of Folk Dualism in Early China,”Cognitive Science 35: 997–1007) by Klein and Klein, defending our interpretation of our data. We also argue that, despite the undeniable challenges involved in qualitatively coding texts from ancient cultures, the standard tools used throughout the cognitive sciences—large quantities of data, coders as blind to the hypothesis as possible, intercoder reliability measures, and statistical analysis—allow the noise of randomly distributed interpretative differences to be distinguished from the signal of genuine historical patterns.     

中介效应的点估计和区间估计:乘积分布法、非参数Bootstrap和MCMC法

针对中介效应ab的抽样分布往往不是正态分布的问题,学者近年提出了三类无需对ab的抽样分布进行任何限制且适用于中、小样本的方法,包括乘积分布法、非参数Bootstrap和马尔科夫链蒙特卡罗(MCMC)方法.采用模拟技术比较了三类方法在中介效应分析中的表现.结果发现:1)有先验信息的MCMC方法的ab点估计最准确;2)有先验信息的MCMC方法的统计功效最高,但付出了低估第Ⅰ类错误率的代价,偏差校正的非参数百分位Bootstrap方法的统计功效其次,但付出了高估第Ⅰ类错误率的代价;3)有先验信息的MCMC方法的中介效应区间估计最准确.结果表明,当有先验信息时,推荐使用有先验信息的MCMC方法;当先验信息不可得时,推荐使用偏差校正的非参数百分位Bootstrap方法.     

The illusion of the framing effect in risky decision making

The present study elucidates that the illusion of framing in risky decisions is induced by the expected losses with the shift of independent or complementary schemata. Throughout three studies, the reversal of risk preferences in the gain and loss frames was confirmed when the expected number of losses was unknown. When it was known, however, the reversal was reduced in Study 2 where the decision makers were informed of all the options in both frames, and eliminated in Study 3 where they elaborated the numbers of lives at stake before making decisions. Further, the complementary schema was more pervasive when the number of expected losses was known, while the independent schema was more common when the number was unknown. These results imply that the illusion of framing is due to the shift of schemata concerning the lives saved and lost. Copyright © 2010 John Wiley & Sons, Ltd.     

Latent variable selection in multidimensional item response theory models using the expectation model selection algorithm

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L₁ regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.     

Collective rumination: When “problem talk” impairs organizational resilience

When adversity strikes, organization members often turn to others in order to vent their negative emotions and receive social support. While social interaction is commonly seen as a major resource for organizational resilience, dysfunctional social interactions and their negative effects on coping with and overcoming adversity are less well understood. This conceptual article develops theory on collective rumination—defined as repetitive and prolonged discussions of adverse events that center on the negative and uncontrollable aspects of the situation—and its detrimental effects on organizational resilience. We elaborate that collective rumination emerges through a vicious circle of a shared negative situational assessment and mutual contagion with highly negative emotions. Based on our theorizing, we propose that collective rumination is negatively related to three core dimensions of organizational resilience: perceptions of control, commitment to joint action, and the acceptance of adversity as a challenge. With our conceptual article, we answer earlier calls to theorize about forms of social interactions that are not valuable but destructive for organizational resilience and elucidate previously neglected social dynamics that are dysfunctional for recovering from adversity.
