The relationship between parental involvement,self-regulated learning,and reading achievement of fifth graders: a path analysis using the ECLS-K database

This study examined the relationship between parental involvement, self-regulated learning (SRL), and reading achievement through analyzing the fifth grade data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (ECLS-K). The results identified six dimensions of parental involvement that are likely to foster SRL of fifth graders: School Involvement, TV Rules, Homework Help, Homework Frequency, Parental Education Expectations, and Extracurricular Activities. Of these three dimensions, Parental Education Expectations, School Involvement, and Homework Help, were found to have stronger effects on SRL; Parental Education Expectations was found to have the strongest beneficial effect on SRL. The results also suggest that SRL mediates the relationship between parental involvement and reading achievement. These results provide a framework for parents to help their children develop SRL skills and guide educators and school administrators as they intend to increase parental involvement and its effectiveness.     

新的视角:从脆弱高自尊看人格障碍症状

从脆弱高自尊视角理解人格障碍症状日益受到研究者的关注。过度的防御是脆弱高自尊的典型特征,不稳定的自我概念建构和不安全的依恋关系影响着脆弱高自尊的形成。偏执、自恋、边缘人格障碍症状的产生、维持和水平与脆弱高自尊有着紧密的联系。未来应更加注意几种脆弱高自尊的相互关系、均衡性及概念的异质性等方面在人格障碍症状领域中的研究。     

Laws,causality and the intentional explanation of action

Whether or not an intentional explanation of action necessarily involves law-like statements is related to another question, namely, is it a causal explanation? The Popper-Hempel Thesis, which answers both questions affirmatively, inevitably faces a dilemma between realistic and universalistic requirements. However, in terms of W.C. Salmon’s concept of causal explanation, intentional explanation can be a causal one even if it does not rely on any laws. Based on this, we are able to refute three characteristic arguments for the claim “reason is not a cause of action,” namely, the “proper logical” argument, the “logical relation” argument, and the “rule-following” argument. This rebuttal suggests that the causal relationship between reason and action can provide a justification for intentional explanations.     

A rational analysis of the effects of memory biases on serial reproduction

Many human interactions involve pieces of information being passed from one person to another, raising the question of how this process of information transmission is affected by the cognitive capacities of the agents involved. Bartlett (1932) explored the influence of memory biases on the “serial reproduction” of information, in which one person’s reconstruction of a stimulus from memory becomes the stimulus seen by the next person. These experiments were done using relatively uncontrolled stimuli, but suggested that serial reproduction could transform information in a way that reflected the biases inherent in memory. We formally analyze serial reproduction using a Bayesian model of reconstruction from memory, giving a general result characterizing the effect of memory biases on information transmission. We then test the predictions of this account in four experiments using simple one-dimensional stimuli. Our results provide theoretical and empirical justification for the idea that serial reproduction reflects memory biases.     

人格特征对胃癌发病的影响

使用Ｃ型行为特征问卷、生活事件量表和ＲＢＣ－Ｃ_（３ｂ）Ｒ、ＲＢＣ－ＩＣ、ＲＣＩＡ、ＣＩＣ和Ｃ_３等免疫功能的检测,调查和检测了３０名胃癌患者和５０名健康者。结果表明：（１）胃癌组比健康组在焦虑、抑郁、愤怒内泄、控制等方面得分高,在愤怒外泄、乐观、社会支持等方面得分低;（２）胃癌患者在确诊前８年内有７６％的患者遇到生活事件,在确诊前３年内有６２％的患者遇到生活事件;（３）胃癌组ＲＢＣ－Ｃ_（３ｂ）Ｒ含量低,ＲＣＩＡ含量和ＣＩＣ水平上升。初步结论：胃癌的发生与患者的一些行为特点有关,主要是抑郁并不表达愤怒;生活事件可作为应激源诱发胃癌;其机制可能与免疫功能有关。     

A Two-Stage Approach to Differentiating Normal and Aberrant Behavior in Computer Based Testing

Statistical methods for identifying aberrances on psychological and educational tests are pivotal to detect flaws in the design of a test or irregular behavior of test takers. Two approaches have been taken in the past to address the challenge of aberrant behavior detection, which are (1) modeling aberrant behavior via mixture modeling methods, and (2) flagging aberrant behavior via residual based outlier detection methods. In this paper, we propose a two-stage method that is conceived of as a combination of both approaches. In the first stage, a mixture hierarchical model is fitted to the response and response time data to distinguish normal and aberrant behaviors using Markov chain Monte Carlo (MCMC) algorithm. In the second stage, a further distinction between rapid guessing and cheating behavior is made at a person level using a Bayesian residual index. Simulation results show that the two-stage method yields accurate item and person parameter estimates, as well as high true detection rate and low false detection rate, under different manipulated conditions mimicking NAEP parameters. A real data example is given in the end to illustrate the potential application of the proposed method.     

内隐人格观对承诺升级的影响——成功期望的中介效应

研究旨在探讨内隐人格观对承诺升级的影响以及期望在其中的中介作用。研究1比较了个体的实体启动、渐变启动和无启动对照三种条件下,个体的承诺升级倾向是否受不同启动类型的影响。结果发现,被启动渐变论的被试与无启动和实体启动的被试相比,前者表现出更多的承诺升级倾向。研究2使用情景模拟任务,分析了个体不同内隐人格观与承诺升级的关系,并在此基础上探讨了成功期望的中介作用。结果发现:(1)个体越倾向渐变论则更多的产生承诺升级行为;(2)成功期望在内隐人格观与承诺升级的关系中起完全中介作用。     

Perceived Social Support Mediates the Relations Between Parental Attachment and Posttraumatic Growth and Resilience in Adolescents Following the Yancheng Tornado

Previous studies have shown that parental attachment is associated with higher levels of posttraumatic growth (PTG) and resilience in individuals who have experienced traumatic events. The present study investigated perceived social support as one pathway in which parental attachment is related to PTG and resilience among Chinese adolescents who have experienced trauma by considering the role of perceived social support. Participants were 443 Chinese adolescents who had experienced a severe tornado a year prior to this study. The results showed that our model fitted the data well [χ²/df = 2.847, comparative fit index (CFI) = 0.970, TLI = 0.963, root mean square error of approximation (RMSEA) (90% CI) = 0.065 (0.056–0.073)] and revealed that perceived social support partially mediated the relationship between parental attachment, and PTG and resilience. The clinical implications and limitations of our research, and recommendations for future research are discussed in this paper.     

Randomized single-blind multicenter trial comparing the effects of standard and augmented acupuncture protocols on sleep quality and depressive symptoms in patients with depression

The study was aimed to compare the effects of standard and augmented acupuncture on depressive symptoms and sleep disturbances in patients with depression. This is a randomized, single-blind, multicenter trial. 140 subjects with clinical insomnia (score of ≥ 7 on the Pittsburgh Sleep Quality Index (PSQI)) were randomized to the standard (LI4, LIV3, EX-HN3, and GV20) or augmented (LI4, LIV3, EX-HN3, GV20, LU7, and KID6, including intradermal needles for sustained treatment) acupuncture groups. Participants received two sessions weekly for six weeks. In trial, The primary outcomes were improvements in PSQI and the Hamilton Rating Scale (HAMD). Secondary outcomes were treatment credibility and adverse events. Outcomes were assessed at baseline, week 3, end of treatment, and 4-week follow-up. From the 105 randomized patients, 89 completed the trial and were included in the final analyses. Better efficacy was observed in the augmented group compared with the standard acupuncture to improve the PSQI and HAMD at week 3, end of treatment, and 4-week follow-up (all p < .05). The HAMD scores improved with time, except between end of treatment and 4-week follow-up, while in the standard group, HAMD scored improved from baseline to week 3, and stopped improving thereafter. The PSQI scores improved with time in the two groups, except between end of treatment and 4-week follow-up. Compared with the standard protocol, the augmented acupuncture protocol had a better efficacy to treat depression and to improve sleep quality of patients with depression.
