乡镇小学生的数学焦虑与数学成绩:数学自我效能感和数学元认知的链式中介作用

采用儿童数学焦虑量表、小学生数学学习自我效能感量表和小学生数学元认知问卷,对508名乡镇中、高年级小学生进行测量,并运用结构方程模型探讨数学焦虑影响数学成绩的内在作用机制。结果发现：（1）数学焦虑显著负向预测数学自我效能感、数学元认知和数学成绩,数学自我效能感显著正向预测数学元认知和数学成绩,数学元认知显著正向预测数学成绩;（2）在数学焦虑对数学成绩的预测中,数学自我效能感和数学元认知均发挥了部分中介作用;（3）数学自我效能感和数学元认知在数学焦虑和数学成绩之间起链式多重中介的作用。因此,数学焦虑除了直接作用于小学生的数学成绩,还可通过数学自我效能感或数学元认知间接影响数学成绩,而且可通过数学自我效能感进而通过数学元认知间接影响数学成绩。文章讨论了上述发现的理论及教育实践含义。     

Differences in Scope Assignments for Child and Adult Speakers of Mandarin

The present study used a Truth Value Judgment Task to investigate whether changes in sentence structure lead to corresponding changes in the assignment of scope relations by Mandarin-speaking children and adults. In one condition, participants were presented with ordinary negative sentences containing disjunction; this condition was designed to verify the existing claim that disjunction is a positive polarity item for adult speakers of Mandarin, but not for child speakers. In a second condition, participants were presented with negative sentences where the disjunction phrase was preposed from object position; this condition was designed to examine the extent to which changes in sentence structure can result in changes in scope assignments to negated disjunctions. The results indicate that the preposed disjunction phrase undergoes reconstruction for children, whereas reconstruction is blocked for adults. This finding also suggests that Mandarin-speaking children and adults exhibit different scope preferences for negated disjunctions, regardless of where the disjunction phrase appears in the surface syntax.     

Autonomic conditioning to monetary and social stimuli and aggression in children

Poor conditioning to punishment, such as loud tones or electric shock, has been proposed as an important factor involved in the etiology of aggressive and psychopathic behavior. However, it is not known whether the association holds when monetary or social stimulus is used as the unconditioned stimulus, and if aggressive individuals also have impaired conditioning to rewards. In this study, skin conductance responses in a conditioning task involving both monetary/social reward and punishment as unconditioned stimuli were assessed in 340 male and female 8‐ to 9‐year‐old children from the community. Children reported their reactive and proactive aggression using the Reactive and Proactive Aggression Questionnaire (RPQ; Raine et al., 2006). Results showed that monetary/social reward and punishment were effective in eliciting physiological classical conditioning in children, and that reduced reward conditioning was associated with high levels of proactive aggression in particular. Findings highlight the importance of distinguishing between reactive and proactive aggression when examining antisocial behavior in children, and suggest that reward‐oriented treatment programs may not be effective for children with more proactive, instrumental aggressive behavior.

     

“Inside out”: Appraisals for achievement emotions from constructive,positive, and negative feedback on writing

Even with the recent surge of research on achievement emotions, few studies have investigated emotions in feedback situations and the appraisals associated with such emotions. The purpose of this study was to examine emotion appraisals of constructive criticism, negative, and positive feedback, to aid us in determining whether these appraisals differed by feedback type. In a task asking them to provide open-ended responses as they imagined receiving feedback on a writing task, undergraduates (N?=?270) gave reasons for why they might experience unpleasant emotions from positive feedback and pleasant emotions from negative feedback along with reasons for both pleasant and unpleasant emotions emanating from constructive feedback. Open coding of responses yielded categories for each emotion-feedback pairing that, across all emotions, were collapsed into five appraisal categories: feedback suggests ways to improve, a mismatch between feedback and task exists, feedback targets the self or one’s ability, feedback says something about the relationship between feedback giver and receiver, and the task is judged for its value. Distributions of appraisal categories distinguished constructive feedback from positive and negative feedback. Implications are drawn for control-value theory and for classroom feedback practices.     

内隐人格观对他人知觉的影响

以大学生为被试,采用投射测验法分离出两类不同性质的内隐人格观,然后通过效价匹配实验和错觉关联实验,初步探讨了内隐人格观对他人知觉的信息加工模式的影响。研究结果表明:(1)跨性格、能力等不同人格属性有共通一致的内隐观;(2)固存观的反面就是渐变观,它们是同一维度的两极;(3)与渐变观者相比,固存观者更易以一种评价性方式知觉他人信息;同时,渐变观者不像固存观者那样对他人特质作出静态判断,而是集中注意力于理解他人行为发生的动态过程。     

相干逻辑关系语义的推理解释

关系语义是相干逻辑中最为重要的语义学之一,但是关系语义一开始就以"纯粹"的形式语义的面貌出现,其中三元关系R的直观意思是什么并不清楚,于是出现了关于关系语义的多种解释。我们认为,R所代表的是推理规则集、前提集和结论集三者之间的关系,据此提出了推理语义。推理语义以推理的形式结构为背景,有明确的直观意义。本文以相干逻辑系统R+为例,证明出推理语义是与关系语义等价的语义。从推理语义与关系语义的这个等价关系上看,推理语义完全可以作为对于关系语义直观解释的一个中间环节。由此不仅使得关系语义有了推理结构的解释,同时说明了相干逻辑是一种关于推理的逻辑。这与相干逻辑产生的历史也完全吻合。     

恋人概念威胁启动削弱自我和恋人面孔优势效应:来自眼动研究的证据

采用眼动记录技术和恋人概念威胁启动范式探讨自我和恋人面孔优势效应的产生和维持过程。结果发现:与概念非威胁启动条件下相比,概念威胁启动条件下,被试搜索恋人面孔时的兴趣区个数和搜索自我面孔时的平均眼跳次数与搜索陌生人面孔时比差异变得不显著;恋人面孔与陌生人面孔在兴趣区内总注视时间上的差异变得不显著。结果表明,自我与恋人面孔存在注意的优先捕获和维持优势,恋人概念的威胁启动会减少对恋人的关注,证明了建立恋人的积极概念是恋人面孔优势效应产生和维持的重要原因。     

Counterfactual comparison modulates fairness consideration in the mini‐ultimatum game: An event‐related potentials study

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.     

Potential Job Facilitation Benefits of “Water Cooler” Conversations: The Importance of Social Interactions in the Workplace

This study looked at the extent to which personality and cultural factors predicted participants’ perceptions of the importance private interactions played in the workplace. The 134 participants read a vignette (where a new employee socially interacted at low or high levels with co-workers) and completed the Big Five Inventory, Social Axioms Survey, and questions concerning expected workplace experiences. Results indicated employees who engaged in high levels of private interaction with co-workers were expected to be better liked, to receive better performance evaluations, were more likely to receive co-worker assistance, and were thought to be more likely chosen for future projects. However, the personality and social axiom variables studied did not significantly interact with social interaction to influence expectations of workplace outcomes.     

Religion and Health: Anxiety,Religiosity, Meaning of Life and Mental Health

We examined the association among anxiety, religiosity, meaning of life and mental health in a nonclinical sample from a Chinese society. Four hundred fifty-one Taiwanese adults (150 males and 300 females) ranging in age from 17 to 73 years (M = 28.9, SD = 11.53) completed measures of Beck Anxiety Inventory, Medical Outcomes Study Health Survey, Perceived Stress Scale, Social Support Scale, and Personal Religiosity Scale (measuring religiosity and meaning of life). Meaning of life has a significant negative correlation with anxiety and a significant positive correlation with mental health and religiosity; however, religiosity does not correlate significantly anxiety and mental health after controlling for demographic measures, social support and physical health. Anxiety explains unique variance in mental health above meaning of life. Meaning of life was found to partially mediate the relationship between anxiety and mental health. These findings suggest that benefits of meaning of life for mental health can be at least partially accounted for by the effects of underlying anxiety.
