锚测验难度水平代表性对垂直量尺化的影响研究

考察了锚测验难度水平对其来源测验水平的代表性对垂直量尺化的影响。采用模拟研究的方法,比较了锚测验难度等于来源测验、位于高低年级测验水平难度区间的第25百分位处及区间第50百分位处时,年级能力分布和垂直量尺特性上的参数返真结果,发现锚题难度水平高于其来源测验非但不会导致垂直量尺化结果变差,在有的情境下反而可能会提高其准确性。研究揭示人们构建垂直量尺时,可以根据内容和其他统计特征的需要对锚测验的难度水平做出适当调整     

Spatial anticipatory attentional bias for threat: Reliable individual differences with RT-based online measurement

Cues that predict the future location of emotional stimuli may evoke an anticipatory form of automatic attentional bias. The reliability of this bias towards threat is uncertain: experimental design may need to be optimized or individual differences may simply be relatively noisy in the general population. The current study therefore aimed to determine the split-half reliability of the bias, in a design with fewer factors and more trials than in previous work. A sample of 63 participants was used for analysis, who performed the cued Visual Probe Task online, which aims to measure an anticipatory attentional bias. The overall bias towards threat was tested and split-half reliability was calculated over even and odd blocks. Results showed a significant bias towards threat and a reliability of around 0.7. The results support systematic individual differences in anticipatory attentional bias and demonstrate that RT-based bias scores, with online data collection, can be reliable.     

Immigrant youth of Indian origin: Generational differences in self-critical perfectionism

A community sample of foreign-born first generation (n = 53) and U.S.-born secondgeneration (n = 57) youth of Indian origin (ages 18–25) was studied. Variables predicting self-critical perfectionism were perceived prejudice, enculturation, and communication difficulty with parents and their interaction with generation status. The differences between the two generations pointed to nuanced self-pressures of Indian immigrant youth, despite good academic standing and middle-class family income. Implications discuss counseling with Indian immigrant youth.     

抚养困难与教养行为的关系及其调节因素

本研究考察了567名2-5岁幼儿母亲的抚养困难与教养行为的关系,并进一步探讨了在高抚养困难情景下母亲教养行为的可能调节因素.结果发现(1)幼儿母亲的抚养困难感受总分与其教养行为的各个侧面均有非常显著的相关,母亲抚养困难程度越高,则其敏感性、参与性、积极情感及对儿童发展的指导性均较低,而其对儿童的消极情感较多;(2)回归分析表明,来自儿童侧面的"积极强化缺乏"、"多动/注意分散"、"不良心境"与"过度要求"以及来自母亲侧面的"缺乏依恋"、"缺乏能力感"等方面的抚养困难是预测母亲教养行为的重要因素;(3)在母亲抚养困难较高的情况下,夫妻双方的受教育水平分别对母亲教养行为的一些侧面具有调节作用.     

逻辑－信念冲突与推理难度对逻辑和信念判断的影响

双加工理论框架下的平行竞争模型和默认干涉模型对推理过程中启发式和分析式加工的启动次序和相互作用的性质提出了不同假设。本研究通过考察被试在信念判断和逻辑判断两种指导语下解决不同难度和不同类型推理问题的正确率和反应时,对两个模型的预测进行了检验。实验结果表明,解决简单问题时,问题类型对信念判断有显著影响,对逻辑判断无显著影响;解决复杂问题时,问题类型对逻辑判断的影响显著大于对信念判断的影响。实验结果支持平行竞争模型的假设,即两类加工在推理过程中同时启动,共同竞争最终的推理反应。     

A Cross‐Cultural Study of Task Specificity in Creativity

This study provides new evidence concerning task specificity in creativity—examining through a cross‐cultural perspective the extent to which performance in graphic versus verbal creativity tasks (domain specificity) and in divergent versus convergent creativity tasks (process specificity) are correlated. The relations between different creativity tasks in monocultural and multicultural samples of Chinese and French children were compared. Electronic versions of the Wallach and Kogan Creativity Test (WKCT , W allach & K ogan, 1965; L au & C heung, 2010) and the Evaluation of Potential Creativity (EP oC; L ubart, B esançon, & B arbot, 2011; B arbot, B esançon, & L ubart, 2011) were used. Both measures showed satisfactory psychometric properties and cross‐cultural structural validity. The results showed that culture has an impact on the structure of creative ability: It appeared that correlation patterns were different across Chinese and French groups and across monocultural and multicultural groups. Such results show that it is crucial to take task specificity into account when investigating the effect of culture on creativity. Indeed, our study implies that cultural differences that are found using one specific creativity task might not be automatically generalizable to all sorts of creativity tasks. Limitations are discussed and perspectives for future research on culture and task specificity in creativity are proposed.     

Stress and Risky Decision Making: Cognitive Reflection,Emotional Learning or Both.

Stressful situations hinder judgement. Effects of stress induced by anticipated public speaking on the Iowa Gambling Task (IGT) were examined. The Cognitive Reflection Test (CRT) was used to examine the relationship between reflective thinking and IGT performance. The stress manipulation increased blood pressure and was associated with poorer IGT and CRT performance. Stressed participants were slower to avoid the disadvantageous decks. Moreover, CRT scores correlated with optimal deck selections indicating the importance of reflective thinking for good performance on the IGT. These correlations were observed in relatively early trials, which challenges the view that analytic thinking is not important when card contingencies are being learned. Data revealed that IGT performance in healthy individuals is not always optimal; stress levels impair performance. A mediation analysis was consistent with the proposal that the stress manipulation reduced IGT performance by impeding reflective thinking. Thus, reflective processing is an important explanation of IGT performance in healthy populations. It was concluded that more reflective participants appear to learn from the outcomes of their decisions even when stressed. Copyright © 2016 John Wiley & Sons, Ltd.     

A socially-based distributed self-organizing algorithm for holonic multi-agent systems: Case study in a task environment

Holonic multi-agent systems (HMASs) have recently attracted many researches in multi-agent systems community. Inspired from the multi-level and self-similar structures of social and biological system, holonic multi-agent systems have been widely used to model and solve complex real-world problems. The main concern in deploying HMASs is the problem of building the hierarchical holonic structure, called holarchy, and dynamically managing it during its lifetime. The way an HMAS is organized has a great impact on its applicability and performance. This paper proposes a self-organizing algorithm to build and manage the holoic structures in multi-agent systems. This algorithm is based on the local information of the agents about other agents they can communicate with. Using common social concepts, like skills, diversity, social exchange theory, and norms in definition of the algorithm, the outcomes of this research can be used in wide ranges of distributed applications. The proposed model is extensively tested in a task allocation problem; and its performance based on various design parameters is studied. Empirical results show that the proposed model properly increases the performance of the system in terms of effectiveness and efficiency.     

The effect of stereotype threat on student-athlete math performance

ObjectivesTo assess whether a subtle stereotype threat of student-athletes would cause a decrease in both academic effort and performance.DesignA 2 (Male/Female) x 2 (Athlete Prime/No Athlete Prime) design was used to assess effort and performance on a math test.MethodA subtle threat manipulation was used to prime half of 60 NCAA Division III student-athletes with their athletic identity prior to taking a difficult math test.ResultsSupporting the hypotheses, student-athletes who were primed with their athletic identity attempted significantly fewer problems and received lower mean math scores than those who were not primed. Contrary to hypotheses, gender did not impact effort or performance, and there was no evidence of buffering effects of priming non-athlete identities.ConclusionsThe results of this experiment provide evidence for stereotype threat effects across genders and into Division III athletes, which potentially impact student-athlete academic performance.     

Knowledge about the distribution of information and group decision making: When and why does it work?

Research has shown that decision-making groups with distributed information perform better when group members know which member is knowledgeable about what. Thus far research has been unable to identify the process responsible for this effect. In the present study, we propose that group members’ task representations mediate the effect of knowledge about the distribution of information on decision performance. Building on this proposition, we also propose that reflection about the task moderates the effect of knowledge about distributed information through its effect on task representations. These hypotheses were put to the test in an experimental study of decision-making groups (N = 125). As predicted, knowledge of distributed information interacted with reflection to affect decision quality. Findings confirmed the proposed mediating role of task representations and information elaboration.
