认知操作背景下在线元认知调节能力的特征

利用认知任务为载体,对在线元认知调节特征进行研究,探讨了在线元认知调节的跨任务一致性和规则特异性。实验采用字母记忆与跟踪击键两种任务作为在线元认知调节的载体,通过逐步增加“提示线索”,观测个体在任务作业上的“成绩”（字母作业任务）或“成绩提高量”（跟踪击键任务）,以此作为评价在线元认知调节能力的指标。结果发现,随着认知任务中潜在规律线索数量的增加,被试能够通过在线元认知调节过程提高其认知作业水平;被试通过认知任务与追述报告分别反映的在线元认知调节水平具有一致性;在线元认知调节一方面具有跨任务情境的一致性,另一方面具有规则发现的差异性。因此,基于认知操作为背景的元认知评价方法能够较好地评估在线元认知调节能力

Dispositional antecedents and outcomes of political skill in organizations: A four-study investigation with convergence

We developed a four-study research plan to examine the dispositional antecedents of political skill and its job performance consequences, and also to incorporate the mediating role of reputation, drawing upon a recent theoretical model of political skill in organizations. Study 1 established the psychometric properties of the two reputation scales used in the present research, and also demonstrated the validity of the self-report reputation measure in Study 4. Study 2 tested, and demonstrated support for, the ‘Affability’ dispositional theme as a predictor of political skill, and political skill as predictor of job performance. In Study 3, the political skill-job performance linkage was replicated, but when reputation was investigated as an intermediate linkage, it was found to fully mediate the relationship between political skill and job performance. Study 4 investigated all the linkages examined in Studies 2 and 3, and found that the ‘Active Influence’ dispositional theme predicted political skill, and that the political skill-job performance relationship was fully mediated by reputation. Collectively, these studies demonstrated support for recent theoretical developments in political skill and reputation, suggesting that political skill has dispositional antecedents, and that political skill demonstrates a significant impact on job performance, through reputation. The strengths and limitations of this research are discussed, and directions for future research are provided.     

学习不良儿童的策略信念与理解水平

使用结构访谈法对120名儿童(其中学习不良儿童60名)的策略信念与策略理解水平进行了研究。结果显示:学习不良儿童组与一般儿童组的差异更多体现在对具体策略的元认知因果解释水平上,他们更多持有较低水平的“信息获得”解释,而对照组儿童则更多持有较高水平的“信息加工”解释,提示对策略理解水平的差异可能是导致学习不良儿童难以将新学到的策略主动应用到其它情景中去的一个重要原因。     

Can Executive Functions Explain the Relationship Between Attention Deficit Hyperactivity Disorder and Social Adjustment?

This study examined the ability of executive functions (EF) to account for the relationship between Attention Deficit Hyperactivity Disorder (ADHD) status and social adjustment as indexed by parent and teacher report and by performance on a standardized observational “chat room” task. Children with the Combined subtype (ADHD-C; n = 23), the Primarily Inattentive Subtype (ADHD-I; n = 33), and non-ADHD controls (n = 36) participated. EF did not mediate the relationship between ADHD status and parent or teacher report of social adjustment. EF accounted for about 40–50% of the variance between ADHD status and the ability of children to detect subtle verbal cues as well as memory for the conversation in the chat room task, but did not mediate the relationship between ADHD and the number of prosocial, hostile, or on-topic statements that were made. Results are consistent with other recent reports, and suggest that the role of EF deficits in the production of social skill deficits in ADHD may not be as prominent as is typically assumed. The implications for the development of intervention programs designed to target core cognitive etiologic factors are discussed.     

初中生的数学估计能力及其与元认知监控的关系

抽取济南市四所中学初一至初三年级547名学生为被试,采用自行设计的数学估计任务和元认知状态问卷(SMI),考察了初中生数学估计能力的现状及其与元认知监控的关系。结果表明:初中生的估计能力总体较差,未显示出稳定的性别差异。元认知监控的四个维度与数学估计表现均存在显著的正相关。从元认知监控对估计成绩的回归分析来看,自我意识可以显著正向预测估计整体表现。其中,计划可以正向预测估数和估算成绩,自我意识可以正向预测估测和估算成绩。文章特别讨论了数学估计与元认知加工之间的具体联系。     

学习不良儿童的元认知偏差：内部线索的影响

通过改变实验材料内部线索,旨在考察内部线索在学习不良儿童元认知偏差形成过程中的影响。实验1发现,学习不良儿童低关联字对的元认知偏差显著高于一般儿童,关联强度对学习判断的影响显著小于对测试成绩的影响;实验2发现,学习不良儿童反向方向字对的元认知偏差显著高于一般儿童,关联方向对学习判断的影响显著小于对测试成绩的影响。综合以上研究发现,相对一般儿童,学习不良儿童存在更大的元认知偏差,内部线索对学习判断和测试成绩的影响不一致模式适用于两组儿童。     

An evaluation of synchronous reinforcement for increasing on-task behavior in preschool children

A synchronous-reinforcement schedule is a type of schedule of covariation in which the onset and offset of the reinforcer covaries with the onset and offset of behavior. This study was a proof-of-concept demonstration of the efficacy of synchronous reinforcement for on-task behavior (completing a preacademic skill) and an evaluation of preschoolers' preference for this schedule in comparison to a more traditional schedule of reinforcement. Specifically, we compared the effects of a synchronous-reinforcement schedule to one in which continuous access to stimuli was delivered at the end of the session and yoked to the duration of on-task behavior that occurred during the session (accumulated reinforcement). Results showed the synchronous-reinforcement schedule was more effective for increasing on-task behavior and preferred by most participants.     

Psycho-perceptual-motor skills are deemed critical to save the penalty corner in international field hockey

In interceptive sports such as field hockey goalkeeping, the psycho-perceptual-motor skill anticipation is vital for performance due to the extreme time constraints associated with saving a goal. The purpose of this study was to understand the beliefs and attitudes of international field hockey goalkeepers and coaches regarding anticipation of the drag-flick in penalty corners. Seven international goalkeepers and five international coaches were interviewed. Using a constructionist and relativist approach to reflexive thematic data analysis, we identified three overarching themes to anticipate the drag-flick, namely, pre-match video analysis, perception and action, and psychological factors. In the first theme, participants reported that pre-match video analysis allowed goalkeepers and coaches to identify the attacking capabilities of opposing teams. This analysis was used to inform defensive structure and save the drag-flick. In the second theme, participants reported that perception and action, which consisted of the pick-up of visual cues and movement execution, was important to anticipate the drag-flick. Goalkeepers reported that they rely heavily on ball flight, which was central in coaches’ approaches in training drills such as to use a projection machine that presents only ball flight information. The third theme, psychological factors, encompassed, psychological resilience, arousal regulation, leadership and communication, and sports intelligence, which were thought to be vital to facilitate anticipation of the drag-flick. The findings of this study have important implications for how to assess and train visual anticipation in time-constrained interceptive sports skills.     

Dyadic judgments based on conflicting samples: The failure to ignore invalid input

The present research demonstrates a so far unrecognized impediment of group performance, metacognitive myopia (Fiedler, 2012). Judges and decision-makers follow the given samples of information uncritically and neglect the metacognitive assessment of the samples' validity. Applying this notion to dyadic judgments, we instructed dyads to jointly estimate conditional probabilities p (Win|A) and p (Win|B) of Lotteries A and B. One person per dyad experienced a valid sample (winning rates conditional on lotteries). The other person experienced an invalid, reverse sample (lotteries conditional on winning). Whereas valid samples provide unbiased estimates of lotteries' winning probabilities, invalid samples can greatly misrepresent the association of winning and lotteries (depending on lottery base rates). Across three experiments, metacognitive myopia—both at the individual and at the dyadic group level—prevented participants from discriminating valid and invalid samples. Group judgments were biased toward erroneous implications of invalid samples, reflecting an equality bias among unequal group members.
