不同趋近动机强度积极情绪对认知控制的影响

情绪的动机维度模型认为, 积极情绪对认知加工的影响受其趋近动机强度的调节, 高、低趋近动机积极情绪对认知加工的影响不同。本研究运用情绪图片诱发被试高、低趋近动机积极情绪, 采用停止信号任务和任务转换作业考察了不同趋近动机强度积极情绪对认知控制的影响。结果发现：(1)与中性条件相比, 高趋近动机积极情绪促进了停止信号任务中Go任务和任务转换作业中重复任务的反应执行。(2)在停止信号任务中, 相对于中性条件, 低趋近动机积极情绪条件下的停止信号反应时显著缩短; 在任务转换作业中, 低趋近动机积极情绪条件下的反应时转换损失和错误率转换损失均显著降低, 而高趋近动机积极情绪条件下的反应时转换损失显著增加。因此, 积极情绪对认知控制的影响受其趋近动机强度的调节, 即低趋近动机积极情绪增强认知灵活性, 提高停止反应与任务转换的速度; 而高趋近动机积极情绪增强认知稳定性, 加快停止信号任务中Go任务和任务转换作业中重复任务的反应执行, 增加了反应时转换损失。     

公交行业一线员工人格特质对工作绩效影响的实证分析--以工作态度作为调节变量

通过问卷调查法,探讨在工作态度调节下大五人格特质与工作绩效的关联。对1277名公交行业一线员工的研究结果表明：(1)人格特质与工作绩效有显著的相关,工作态度在这一关系中起到调节作用。在高工作态度中,人格特质与任务绩效联系较为紧密,工作绩效的良好预测指标是尽责性和外向性;在低工作态度中,人格特质与关系绩效联系较为紧密,工作绩效的良好预测指标是宜人性和外向性。(2)在高工作态度的环境中,人们更看重工作的完成;在低工作态度的环境中,人们更看重关系的协调。工作态度调节着人格特质对工作绩效的影响。     

ADHD and Behavioral Inhibition: A Re-examination of the Stop-signal Task

The current study investigates two recently identified threats to the construct validity of behavioral inhibition as a core deficit of attention-deficit/hyperactivity disorder (ADHD) based on the stop-signal task: calculation of mean reaction time from go-trials presented adjacent to intermittent stop-trials, and non-reporting of the stop-signal delay metric. Children with ADHD (n = 12) and typically developing (TD) children (n = 11) were administered the standard stop-signal task and three variant stop-signal conditions. These included a no-tone condition administered without the presentation of an auditory tone; an ignore-tone condition that presented a neutral (i.e., not associated with stopping) auditory tone; and a second ignore-tone condition that presented a neutral auditory tone after the tone had been previously paired with stopping. Children with ADHD exhibited significantly slower and more variable reaction times to go-stimuli, and slower stop-signal reaction times relative to TD controls. Stop-signal delay was not significantly different between groups, and both groups’ go-trial reaction times slowed following meaningful tones. Collectively, these findings corroborate recent meta-analyses and indicate that previous findings of stop-signal performance deficits in ADHD reflect slower and more variable responding to visually presented stimuli and concurrent processing of a second stimulus, rather than deficits of motor behavioral inhibition.     

变革型领导对员工绩效和满意度的影响：心理资本的中介作用及程序公平的调节作用

通过对国内一家企业共785位员工及其直接主管的问卷调查, 考察了下属心理资本在变革型领导与下属工作绩效及满意度之间关系的中介作用以及程序公平对该关系的调节作用。研究结果显示：1)下属的心理资本与其工作绩效和满意度正向相关; 2)下属的心理资本部分中介了变革型领导对下属工作绩效及满意度的正向关系; 3) 下属的程序公平调节了变革型领导对下属心理资本的影响。具体而言, 下属的程序公平感越高, 变革型领导与下属心理资本的正向关系越强, 反之越弱; 4) 进一步地, 程序公平调节了下属心理资本对变革型领导－工作绩效和满意度的中介作用, 即：程序公平感越高, 变革型领导通过心理资本对下属的工作绩效和满意度所产生的作用就越强, 反之越弱。最后讨论了该研究的理论意义和应用价值。     

四卡问题的内容促进效应的实验研究

本研究设计了２种抽象材料和４种具体材料的四卡问题,对４３６名大学生进行测试,以考察被试解决四卡问题时所采用的思维方式并检验命题内容对推理的影响。结果表明,四卡问题十分困难,具体内容的四卡问题并不能产生促进效应,大学生的推理表现出“匹配偏向”的特点。     

对当前量化绩效考核的反思

通过文献研究和哲学反思等方法对高校和医疗卫生系统的量化绩效考核进行研究。认为绩效考核不能偏离组织使命,不能弱化职业精神。如何在职业精神和组织使命中一些重要内容难以进入量化指标的情况下合理设计绩效考核体系值得深思。其次,在科研绩效考核中,《科学引文索引》(science citation index,SCI)作为科研论文的产出指标有一定合理性,但也不能唯SCI论;要重视基金,因为它反映了计划性科学的价值,但也不能唯基金论;要重视量化评估,却不能唯量化评估。要保证绩效考核正确导向,就必须纠正泛行政化和官本位倾向,就必须坚持科学化、推进民主化。     

The competitive reaction time task: The development and scientific utility of a flexible laboratory aggression paradigm

Laboratory measures play an important role in the study of aggression because they allow researchers to make causal inferences. However, these measures have also been criticized. In particular, the competitive reaction time task (CRTT) has been criticized for allowing aggression to be operationalized in multiple ways, leaving it susceptible to “p-hacking.” This article describes the development of the CRTT and the ways in which its paradigm flexibility and analytic flexibility allows it to test a wide range of hypotheses and research questions. This flexibility gives the CRTT significant scientific utility, but as with any research paradigm, comes with the obligation that it has to be used with integrity. Although safeguards exist and there is little evidence of misuse, study preregistration can increase confidence in CRTT findings. The importance of findings such as those of Hyatt et al. (in press), which provide further evidence for the validity of the CRTT, are also noted.     

Cognitive Task Analysis for Implicit Knowledge About Visual Representations With Similarity Learning Methods

Visual representations are prevalent in STEM instruction. To benefit from visuals, students need representational competencies that enable them to see meaningful information. Most research has focused on explicit conceptual representational competencies, but implicit perceptual competencies might also allow students to efficiently see meaningful information in visuals. Most common methods to assess students’ representational competencies rely on verbal explanations or assume explicit attention. However, because perceptual competencies are implicit and not necessarily verbally accessible, these methods are ill‐equipped to assess them. We address these shortcomings with a method that draws on similarity learning, a machine learning technique that detects visual features that account for participants’ responses to triplet comparisons of visuals. In Experiment 1, 614 chemistry students judged the similarity of Lewis structures and in Experiment 2, 489 students judged the similarity of ball‐and‐stick models. Our results showed that our method can detect visual features that drive students’ perception and suggested that students’ conceptual knowledge about molecules informed perceptual competencies through top‐down processes. Furthermore, Experiment 2 tested whether we can improve the efficiency of the method with active sampling. Results showed that random sampling yielded higher accuracy than active sampling for small sample sizes. Together, the experiments provide the first method to assess students’ perceptual competencies implicitly, without requiring verbalization or assuming explicit visual attention. These findings have implications for the design of instructional interventions that help students acquire perceptual representational competencies.     

Early understanding of the socially mediated representational function of pictures

The present two studies investigated whether toddlers’ ability to use pictures in problem solving could be facilitated by making available the social context in which pictures were created. To make this social context available, we introduced an Experimental treatment in which the creator was intentionally drawing different objects. In Experiment-1, due to this treatment, children performed better in the Test in which the Experimenter was drawing the Test-pictures of the retrieval task. In Experiment-2, after the same Experimental treatment the facilitative effect was replicated although the social context was removed in the Test phase by using pre-drawn Test-pictures without any drawing action in the retrieval task. The results suggest that a treatment which offers the opportunity to understand the socially mediated representational function of pictures enables children to perform better when contextualizing pictures in current reality. These two experiments revealed a novel way to facilitate children’s picture comprehension by identifying an underlying factor that can explain children’s difficulty in picture comprehension.
