以120名4~7岁儿童为研究对象, 采用改编后的对偶选择范式, 探讨儿童基于两种不同的可信度特质(善良和能力)和两个与信任有关的情景进行的信任判断能力。结果显示:(1)4~7岁儿童在善良情景正确判断率都高于随机水平, 而在能力情景中, 仅6岁和7岁儿童的正确率显著高于随机水平; (2)6岁儿童虽然已经具备依据可信度特质和情景做出正确的信任判断的能力, 但是在善意情景中的信任判断能力要好于在能力情景中的信任判断能力, 而7岁儿童在能力情景和善意情景中的信任判断能力则没有显著差异;(3)同时考虑两种可信度特质和情景时, 5~7 岁儿童的正确率高于了随机水平, 并且6、7岁儿童的正确率要显著高于5岁儿童。这些结果表明儿童到了5岁才初步发展出同时考虑可信度特质和情景进行信任判断的能力, 直到7岁这一能力才相对成熟和稳定。  相似文献

依据错误驱动的学习理论,行为预期结果与实际结果之间的不匹配即预期错误(Predictionerror,PE)是学习产生的驱动因素。作为显著性信息中的一种,预期错误和物理显著性、惊讶、新异性等存在信息加工阶段的不同,与记忆更新的关系也有差异。近年来,记忆再巩固干预范式(reconsolidation interference)被证明可用于人类条件性恐惧记忆的更新,其中记忆提取激活阶段所包含的预期错误起到了引发记忆“去稳定”、开启记忆再巩固的关键作用。在促进恐惧记忆更新的行为机制上,PE被认为是记忆去稳定的必要非充分条件。记忆提取必须包含适量的PE,但其引发的是记忆去稳定、消退还是中间状态,还需结合记忆本身性质确定。在促进恐惧记忆更新的神经机制上,杏仁核、导水管周围灰质(PAG)、海马均在PE探测和计算过程中具有重要作用;前额叶皮层(PFC)及其亚区在PE开启记忆再巩固过程中扮演了重要角色。上述过程又受到神经系统中特定神经递质的重要调节,尤其是多巴胺能和谷氨酸能。未来研究应进一步探索基于PE计算模型的量化研究,整合PE与其他边界条件的交互作用,考察不同类型显著性在记忆再巩固中的作用等;并亟...  相似文献

以361名9~12岁儿童为被试,采用同伴互评和同伴提名的方法考察了好友可信度与9~12岁儿童信任的关系,以及年龄在好友可信度与儿童信任关系上的调节效应。结果表明:总体而言,好友可信度对儿童信任有正向的预测作用。其次,年龄在好友可信度与儿童信任的关系上具有调节效应,随着年龄的增长,好友可信度对儿童信任的正向预测作用也随之增大。  相似文献

This article reviews the empirical research on the prediction of reoffending among sexual offenders. The major predictors of sexual-offense recidivism are factors related to sexual deviance (e.g., deviant sexual preferences, previous sex crimes) and, to a lesser extent, criminal lifestyle (e.g., antisocial personality disorder, total number of prior offenses). The factors that predict general recidivism among sex offenders are the same as the factors that predict general recidivism among nonsexual criminals (e.g., juvenile delinquency, prior violent offenses). Given that there are special predictors of sexual recidivism, evaluators should consider separately the risk for sexual and nonsexual recidivism.  相似文献

Vigilance towards deception is investigated in 3- to-5-year-old children: (i) In Study 1, children as young as 3 years of age prefer the testimony of a benevolent rather than of a malevolent communicator. (ii) In Study 2, only at the age of four do children show understanding of the falsity of a lie uttered by a communicator described as a liar. (iii) In Study 3, the ability to recognize a lie when the communicator is described as intending to deceive the child emerges around four and improves throughout the fifth and sixth year of life. On the basis of this evidence, we suggest that preference for the testimony of a benevolent communicator, understanding of the epistemic aspects of deception, and understanding of its intentional aspects are three functionally and developmentally distinct components of epistemic vigilance.  相似文献

Fuzzy-Trace Theory and False Memory   总被引:5,自引:0,他引:5  
A key problem confronting theories of false memory is that false-memory phenomena are so diverse: Some are characteristic of controlled laboratory tasks, others of everyday life; some occur for traumatic events with legal consequences, others for innocuous events; some are characteristic of one developmental level, others of another developmental level. Fuzzy-trace theory explains false memories via a small set of principles that implement a single representational distinction. Those principles generate new predictions, some of which are counterintuitive.  相似文献

We present three studies exploring 2- to 4-year-olds’ imitation on witnessing a model whose questionable tool use choices suggested her untrustworthiness. In Study 1, children observed the model accidentally select a physically optimal tool for a task and then intentionally reject it for one that was functionally nonaffordant. When asked to perform the task for her, children at all ages ignored the model’s intentional cues and selected the optimal tool. Study 2 found that when the model’s nonaffordant tool choice was emphasized by claims about its design, 3-year-olds increased imitation. They also imitated, as did 2-year-olds, when the model selected a suboptimal rather than nonaffordant tool. The 4-year-olds consistently avoided imitation. Study 3 replicated these findings with new tools and participants. Additional measures indicated that knowledge about artifact design predicted children’s tendency to ignore the model. These results shed light on developmental trends in the social and cognitive functions of imitation.  相似文献

The paper outlines an approach to the formal representation of signalling conventions, emphasising the prominent role played therein by a particular type of normative modality. It is then argued that, in terms of inferencing related to this modality, a solution can be given to the task J.L. Austin set but failed to resolve: finding a criterion for distinguishing between what Austin called constatives and performatives. The remainder of the paper indicates the importance of the normative modality in understanding a closely related issue: reasoning about trust in communication scenarios; this, in turn, facilitates a clear formal articulation of the role of a Trusted Third Party in trade communication.  相似文献

This paper explores the association between social capital and average happiness in the United States. Social capital is measured as a multidimensional concept consisting of social trust and two different indicators of sociability. In order to employ the variation both over time and across states, the data are organized in either a panel of nine US Census regions over the period 1983–1998 or in averages over this period in a cross-section of 48 states. The results show that social trust is positively associated with happiness while the potential effects of informal sociability at the level of society only appear significant in the regional estimates. The findings document the importance of social trust for average happiness but also hold more general implications for social capital theory.  相似文献

This paper reviews and evaluates a set of studies that utilize dynamic systems (DS) principles, and in two cases dynamic systems methods, for predicting antisocial development and other behavioral outcomes. I suggest that the emphasis of DS approaches on process and nonlinear causation is very different from the emphasis in developmental psychopathology on prediction, yet the marriage of these approaches is necessary to capture the complex interactions that give rise to problematic trajectories. The studies reviewed do indeed uncover predictive relations that would have been difficult to conceptualize or impossible to find using more traditional strategies. In discussing these studies. I suggest DS interpretations of emerging individual differences, phase-specific change, sleeper effects, mediating variables, and behavioral rigidity versus malleability, in the context of developmental prediction. I also discuss the advantages of moving from DS concepts to DS methods in clinical-developmental research.  相似文献
