大学生问题发现过程的元认知特点研究

用出声思维法对大学生进行个别实验,考察在矛盾式与潜藏式两类情境中问题发现过程的元认知评价、元认知监控和元认知策略的特点。40名大学生参与实验,高低能力组被试各20名。研究结果显示：（1）大学生自评分数与问题总数量和总评分之间相关显著,高能力组学生的自评分数高于低能力组。（2）大学生倾向于使用价值性判断和原文分析两个标准来选择问题,高能力组学生对选问理由的阐述优于低能力组,大学生在矛盾情境中对选问理由的阐述优于潜藏情境。（3）高能力组学生在修正策略的使用上多于低能力组。     

Metamemorial Knowledge of Good and Poor Readers: A Developmental Perspective

Torgesen (1977b) suggested that reading-disabled children exhibit passivity in learning situations; they fail to employ strategies that enhance learning. Such passivity resembles that of young children who lack awareness of the utility of strategies that enhance cognitive efficiency in a variety of situations (e.g., listening, reading, and memory tasks). Such awareness is one aspect of metamemory, and children with reading problems may lag behind other children with regard to this aspect. Good readers (second-, third-, and fifth-graders) and poor readers (third- and fifth-graders) were interviewed to determine their level of knowledge about a number of variables that affect memory in real-life situations. Each child was asked questions concerning his or her memory ability, and then was shown pictures depicting manipulations of the variables number, time, category, and strategy, as well as two-way combinations of the four variables. Results generally failed to support the developmental lag hypothesis. Poor readers did not resemble younger children in their awareness of variables that affect memory but exhibited knowledge commensurate with that of good readers in the same grade.     

元认知视角下的强迫症的特征、模型及干预

强迫症的元认知模型认为, 元认知是理解强迫症病理的关键。强迫症患者存在错误的元认知知识信念、消极的元认知体验及不恰当使用元认知策略等问题。强迫症的元认知疗法强调思维过程(如自我聚焦注意、对担忧不变的思维风格和威胁调节的注意策略等)的重要性, 而非思维的具体内容, 并在个体心理干预、团体心理干预等研究中显示出较好的疗效。未来研究应从认知神经科学等视角考查强迫症的记忆等元认知特征, 并进一步验证和修正强迫症的元认知模型。     

元认知的神经机制:元认知功能、脑区与脑网络

元认知是指个体对当前进行的认知活动的监测和调节。通过对元认知神经机制研究的梳理,归纳出两条研究主线:一条主线以具体元认知加工的脑区激活研究为主,主要考察元认知与认知过程的分离及典型元认知加工的共享性和特异性。研究发现元认知加工主要与前额叶有关,还涉及脑岛、顶叶、颞叶和楔前叶等部分脑区。另一条主线探讨广泛的元认知功能与广泛大脑网络的相关。研究提出了大脑的“元认知网络”的概念,发现脑损伤或病变造成的元认知功能损伤与脑功能网络有关,而非固定在某一特定脑区。建议未来的研究应重视四个方面的研究:元认知加工的具体脑区和脑功能网络,元认知神经机制的分离,元认知脑功能的损伤和元认知训练的改善作用,以及基于神经机制研究的元认知模型的建构与修正。     

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.     

Reply to Commentaries

In our response, we address four themes arising from the commentaries. First, we discuss the distinction between cognition and metacognition and show how to draw it within our framework. Next, we explain how metacognition differs from social cognition. The underlying mechanisms of metacognitive development are then elucidated in terms of interaction patterns. Finally, we consider measures of metacognition and suitable methods for investigating it. Copyright © 2013 John Wiley & Sons, Ltd.     

Parental Emotion Coaching: Associations With Self-Regulation in Aggressive/Rejected and Low Aggressive/Popular Children

This study investigated associations between maternal and paternal emotion coaching and the self-regulation skills of kindergarten and first-grade children. Participants were 54 children categorized as either aggressive/rejected or low aggressive/popular by peer reports. Findings indicated a statistical trend for fathers of low aggressive/popular children to engage in more emotion coaching than fathers of aggressive/rejected children. Paternal emotion coaching accounted for significant variance in children's regulation of attention. Maternal emotion coaching moderated the relation between children's status and regulation of emotion. Findings suggest that interventions focused on parental emotion coaching may prove beneficial for increasing the self-regulation and attention skills of children with social and conduct problems.     

认知不公正：认知维度下理解医患互动的视角

从认知不公正的理论视角出发对医患互动予以重新审视。研究发现,医患间的认知不公正不仅阻碍医患间证言知识的有效传递,凸显二者在认知预期与互动意愿上的差异,而且呈现出波动性、形态多样性和伤害间接性的特点,加速医患互动工具化的同时,加剧双方弥合信任的难度。尽管医患主动采取“理直气和”与“关系就医”的调适策略,但医患关系的改善以及认知不公正的消除不仅是医疗领域内医患双方的合作问题,还需要从更广泛的社会维度出发,迈向扩大的医患共同体。

     

伪装情绪的人际影响及其作用机制

伪装情绪是指在情绪交互的过程中, 人们展现实际不存在的积极或消极情绪, 放大亦或是压抑原本的情绪。伪装情绪是一种策略选择的结果, 表现者所展现的情绪在当下可能并未发生, 但却能在某种程度上令人信服。目前关于伪装情绪的研究比较分散, 对于伪装情绪人际影响及其作用机制还存在着一定争议。现有文献多从博弈过程、亲社会行为情境、组织情境和领导效果四个方面对伪装情绪的人际效应进行探讨, 其中相关的机制包括情绪接受者的情感反应及“以己度人”的内心过程。未来的研究可以从情绪接受者、群体伪装、伪装情绪效价、认知神经机制以及文化等方面, 对伪装情绪展开深入系统性的研究。     

The effect of induced sadness and moderate depression on attention networks

This study investigates how sadness and minor/moderate depression influences the three functions of attention: alerting, orienting, and executive control using the Attention Network Test. The aim of the study is to investigate whether minor-to-moderate depression is more similar to sadness or clinical depression with regard to attentional processing. It was predicted that both induced sadness and minor-to-moderate depression will influence executive control by narrowing spatial attention and in turn this will lead to less interference from the flanker items (i.e. less effects of congruency) due to a focused attentional state. No differences were predicted for alerting or orienting functions. The results from the two experiments, the first inducing sadness (Experiment 1) and the second measuring subclinical depression (Experiment 2), show that, as expected, participants who are sad or minor to moderately depressed showed less flanker interference compared to participants who were neither sad nor depressed. This study provides strong evidence, that irrespective of its aetiology, sadness and minor/moderate depression have similar effects on spatial attention.     

The metaphysics of cognitive artefacts

This article looks at some of the metaphysical properties of cognitive artefacts. It first identifies and demarcates the target domain by conceptualizing this class of artefacts as a functional kind. Building on the work of Beth Preston, a pluralist notion of functional kind is developed, one that includes artefacts with proper functions and system functions. Those with proper functions have a history of cultural selection, whereas those with system functions are improvised uses of initially non-cognitive artefacts. Having identified the target domain, it then briefly looks at the multiple usability of physical structures and the multiple realizability of cognitive function. Further developing insights from the “dual nature of artefacts thesis”, the article ends with conceptualizing the structure–function relations of cognitive artefacts. More specifically, it unpacks the relation between physical structure, representational structure, information, and cognitive function.     

Epistemic Possibility and the Necessity of Origin

The necessity of origin suggests that a person’s identity is determined by the particular pair of gametes from which the person originated. An implication is that speculative scenarios concerning how we might otherwise have been had our gametic origins been different are dismissed as being metaphysically impossible. Given, however, that many of these speculations are intelligible and commonplace in the discourses of competent speakers, it is overhasty to dismiss them as mistakes. This paper offers a way of understanding these speculations that does not commit them to incoherence but aims to make the best sense of what they are expressing. Using the philosophical framework of two-dimensional semantics, it proposes that the speculative scenarios are best analysed as epistemic possibilities, rather than as metaphysical possibilities. It then explores some implications of this analysis for the ethical challenges associated with the non-identity problem.

注意瞬脱范式中的知觉负载对情绪面孔加工的影响

情绪性刺激的加工是否受注意影响目前尚存争论。基于许多操纵空间注意焦点的研究未能在注意资源的分配上进行精确的调节, 本实验将时间维度的注意瞬脱范式与负载理论相结合, 通过调节注意瞬脱中T1刺激物知觉负载水平的高低(箭头朝向相同与否), 观察被试在四种时间延迟条件下(延迟2, 延迟3, 延迟5, 延迟8)T2目标侦测任务恐惧和中性面孔的反应正确率, 从而对情绪性刺激的加工特征进行研究。实验发现：对恐惧面孔侦测的正确率在高知觉负载条件下显著降低, 而中性面孔则不受知觉负载水平影响, 并且这种高知觉负载对恐惧面孔加工的抑制作用仅发生在注意瞬脱中的短延迟条件下。说明在知觉加工资源和注意调节作用同时受限的情况下恐惧面孔的优势加工受到限制, 提示情绪性刺激的加工与中性刺激相比消耗的加工资源较少, 并依赖于注意的调控。     

耳鸣的心理机制

现有研究表明, 耳鸣给患者带来的心理问题比机体自身的病理损伤更为严重, 其中最突出的是患者的注意与情绪问题。近年来, 研究者利用多种方法从多角度证实了耳鸣患者存在不同程度的注意障碍; 同时, 影像学研究也发现部分情绪脑区的活性增强与耳鸣患者的情绪障碍显著相关。这些研究成果不仅为耳鸣的客观评估提供了可行性依据, 也为心理治疗的进一步发展奠定了基础。随着耳鸣患者对生活质量要求的提高, 未来耳鸣研究应着重帮助患者缓解负性情绪, 纠正不良行为, 帮助其重新过上正常的生活。     

Emotions in action through the looking glass1

Abstract: The paper aims at highlighting how our primary understanding of others’ actions is rooted in the mirror mechanism. To this end, the anatomical architecture of the mirror neuron system for action will be outlined as well as its role in grasping goals and intentions in others’ motor behaviour. One further step through the looking glass of social cognition will be referring to the ubiquitous emotional colouring of actions and considering its links with the motor domain. This will allow a clearer perspective on the mechanism underlying our abilities for emotional understanding and on cases in which these abilities are amiss, as in autistic spectrum disorders.     

Effects of Developmental Task Constraints on Kinematic Synergies during Catching in Children with Developmental Delays

Abstract

The aim of this study was to examine effects of a task intervention on kinematic synergies in catching. Participants were young children (5.58?±?0.52?years) with the lowest scores on two-hand catching, according to assessments with the Test of Gross Motor Development-2 (TGMD-2) and were allocated into two groups. The constraints group took part in an 8-week intervention, whereas the control group experienced a typical physical education. Both groups were assessed with motor development and kinematic coordination measures with a catching task with a ball thrown from 2?m distance. Kinematic variables were recorded using a wireless motion capture system. A principal component analysis (PCA) was used to measure the kinematic synergies formed among active body parts. Two synergies that emerged in catching were mainly utilised for “reaching” and “catching” the ball. The control group tended to re-organise the majority of active body parts into two functional units in all phases, whereas the constraints group adapted their active parts into functional units according to the requirement of the novel movement in the transfer task. The findings of this study suggested that task constraints could facilitate object control by re-organisation of active body parts into functional synergies to achieve successful performance.
