认知重评能有效降低个体对情感刺激的负性情绪体验, 但指导性认知重评在恐惧记忆治疗中效果存在争议。本文将认知重评范式与辨别式条件恐惧反应范式结合, 以效价和US预期值为指标, 探讨指导性认知重评训练对恐惧情绪习得和消退的影响效果。以低认知重评能力个体为被试, 在实验前24 h进行指导性认知重评训练。条件性恐惧任务为期2天, 第一天完成条件性恐惧的习得和消退任务, 第二天完成条件性恐惧的再消退任务。结果显示, 经过重评训练后个体在条件性恐惧任务中的恐惧情绪效价显著较低, 说明认知重评有效降低低认知重评能力个体在急性应激状态下的负性情绪体验。所有被试均成功完成辨别式条件性恐惧的习得和消退任务, 因此重评训练并不削弱个体对危险或者安全信息的辨别能力。但在条件性恐惧的消退过程中, 认知重评指导训练加快了恐惧消退, 且24 h后测得的条件性恐惧程度显著较低, 说明指导性重评提高了条件性恐惧记忆的消退效率, 并减弱了条件性恐惧的消退返回。 相似文献

The free recall measure is one of the most popular measures in memory research.
Using this measure, researchers can assess not only the amount of recall but
also the strategy participants used to recall the material. Category
clustering is a strategy participants often use when the input list
is categorized. Unfortunately, computing category clustering measures is
laborious. The present paper introduces a calculator that computes these
measures for each participant using a platform that is accessible to most
researchers in an attempt to make these measures more user-friendly. 相似文献

The argumentative theory of reasoning (Mercier & Sperber, in press-c) claims that reasoning evolved for argumentation: to find and evaluate arguments in dialogic contexts. The theory has drawn most of its supportive evidence from work with adults, leaving open the possibility that argumentive features of reasoning are in fact entirely learned. Evidence is reviewed here suggesting that the special relation between reasoning and argumentation holds at all ages. More specifically, it is argued that (a) children possess at least rudimentary argument skills, (b) they are able to reap the benefits of social reasoning from very early on, (c) confirmation bias is present as soon as they start to argue, and (d) children can be victims of the same biases that affect adults when they use reasoning in the wrong contexts. These claims strengthen the argumentative theory of reasoning and support a call for more research on the interactive features of reasoning in both adults and children. 相似文献

人们常常发现自己对某一情景有些熟悉, 但又想不起以前有关的经历。对这种熟悉感的理论解释, 一种观点认为熟悉感来自一种较弱的记忆形式, 与有回忆情况下的再认属于同一加工过程(single-process models, SPM)。另一种观点则认为, 熟悉感来自一种基于熟悉性的再认, 与基于回想的再认相互独立(dual-process theories, DPT)。在实验室, 评估熟悉性与回想是否相互独立的基本方法是寻找两者分离的证据。本文尝试梳理无线索回忆再认(recognition without cued recall, RWCR)范式的研究, 结果显示:熟悉性对某种特殊的概念加工和整体特征的知觉加工要比回想更加敏感, 并没有支持SPM关于回想和熟悉性各自对意义加工和局部特征的知觉加工更加敏感的推断。而且RWCR研究还观测到熟悉性与回想在行为和神经成像方面的实验性分离, 支持了DPT关于熟悉性与回想相互独立的推断。最后, 本文从熟悉性的深层机制和中英文材料对RWCR的不同影响出发, 对未来研究提出展望。 相似文献

同伴互动类型对三年级小学生写作水平的影响 总被引:1,自引:0,他引:1
研究通过对比同伴辅导、合作、协作等三种同伴互动写作方式与个体化写作教学干预前后,三年级学生独立写作水平的变化,了解同伴互动类型对初学者写作水平的影响.结果发现,和个体化写作相比,三种同伴互动写作方式均更有利于整体写作水平和"结构"维度写作水平的提高;但合作写作最为突出,不仅在各个维度都优于个体化写作,而且在"选材"维度上还优,于同伴辅导写作和协作写作.这说明,社会性互动有利于初学者写作水平的提高,且主要表现为提升记叙文的结构完整性和层次清楚性;但只有兼顾"个人责任"和"高平等性、相互性",社会性互动对写作的促进作用才能更加充分地发挥. 相似文献

Coordinating cognition: the costs and benefits of shared gaze during collaborative search 总被引:1,自引:0,他引:1
Collaboration has its benefits, but coordination has its costs. We explored the potential for remotely located pairs of people to collaborate during visual search, using shared gaze and speech. Pairs of searchers wearing eyetrackers jointly performed an O-in-Qs search task alone, or in one of three collaboration conditions: shared gaze (with one searcher seeing a gaze-cursor indicating where the other was looking, and vice versa), shared-voice (by speaking to each other), and shared-gaze-plus-voice (by using both gaze-cursors and speech). Although collaborating pairs performed better than solitary searchers, search in the shared gaze condition was best of all: twice as fast and efficient as solitary search. People can successfully communicate and coordinate their searching labor using shared gaze alone. Strikingly, shared gaze search was even faster than shared-gaze-plus-voice search; speaking incurred substantial coordination costs. We conclude that shared gaze affords a highly efficient method of coordinating parallel activity in a time-critical spatial task. 相似文献

The remarkable successes of the physical sciences have been built on highly general quantitative laws, which serve as the basis for understanding an enormous variety of specific physical systems. How far is it possible to construct universal principles in the cognitive sciences, in terms of which specific aspects of perception, memory, or decision making might be modelled? Following Shepard (e.g., 1987 ), it is argued that some universal principles may be attainable in cognitive science. Here, 2 examples are proposed: the simplicity principle (which states that the cognitive system prefers patterns that provide simpler explanations of available data); and the scale‐invariance principle, which states that many cognitive phenomena are independent of the scale of relevant underlying physical variables, such as time, space, luminance, or sound pressure. This article illustrates how principles may be combined to explain specific cognitive processes by using these principles to derive SIMPLE, a formal model of memory for serial order ( Brown, Neath, & Chater, 2007 ), and briefly mentions some extensions to models of identification and categorization. This article also considers the scope and limitations of universal laws in cognitive science. 相似文献

Retelling Is Not the Same as Recalling: Implications for Memory 总被引:1,自引:0,他引:1
Elizabeth J. Marsh 《Current directions in psychological science》2007,16(1):16-20
ABSTRACT— In contrast to laboratory free recall (which emphasizes detailed and accurate remembering), conversational retellings depend upon the speaker's goals, the audience, and the social context more generally. Because memories are frequently retrieved in social contexts, retellings of events are often incomplete or distorted, with consequences for later memory. Selective rehearsal contributes to the memory effects, as does the schema activated during retelling. Retellings can be linked to memory errors observed in domains such as eyewitness testimony and flashbulb memories; in all of these situations, people retell events rather than engage in verbatim remembering. 相似文献

Abstract: Two experiments were carried out to investigate the changes across age groups in the effects of self-corrected elaboration on incidental memory. Each participant performed an orienting task involving three conditions: self-corrected, self-generated and experimenter-provided elaboration. The orienting task was followed by free recall tests. In Experiment 1, the participants were sixth-grade and second-grade students. For sixth-grade students the self-corrected elaboration led to a better free recall than the other two elaborations, whereas for the second-grade students, no difference was observed between any of the three elaborations. In Experiment 2, using a longer word list than that in Experiment 1, the participants were undergraduates. The self-corrected and self-generated elaborations led to a better free recall than the experimenter-provided elaboration, and no difference between the former two elaborations was observed. The results obtained from these two experiments were interpreted as showing that the effectiveness of a self-corrected elaboration depends on the participants' age. 相似文献
