内隐学习和外显学习关系评述 总被引:24,自引:0,他引:24
文章从内隐学习与外显学习的区别、联系以及相互作用三方面,对这两个概念集合间的关系进行了辨析。最初,内隐学习这一概念的提出,是源于其与外显学习在现象学、实验操作、神经生理学以及学习机制等方面的诸多不同。近年来,虽然内隐学习的独立地位已被充分确立,但是,也有越来越多的证据表明,内隐学习和外显学习之间的独立性是相对的,它们之间存在紧密的联系和相互作用,任何一个学习任务都是内隐和外显学习的结合物。最后,作者结合自己的实验研究进一步提出了,内隐学习和外显学习之间相互权衡的动态关系。 相似文献

外显知识对运动技能内隐学习的影响 总被引:3,自引:0,他引:3
总结了近年来关于外显知识对运动技能内隐学习影响的研究。提出外显知识对内隐学习存在影响,但其作用的大小及其性质取决于外显知识的呈现时间、内容、内隐规则的可觉察程度、认知负荷以及压力等因素。提供外显知识既可能有利于任务的完成,也可能激发与任务规则无关的注意过程,阻碍内隐学习。外显知识可影响行为,却不一定能被有意识地提取。外显知识对学习者的认知过程和动作模式均会产生影响。 相似文献

CLARION是一个与其它认知理论明显不同的计算认知模型,它可用来研究内隐和外显学习交互作用的各种定量数据。通过对经典内隐学习任务(如系列反应时任务、加工控制任务及其他高级认知加工任务)的模拟实验,在与人类实验数据的拟合上,CLARION展示出比以往认知模型更好的性能。它主要有两个特征:一是对内隐学习和外显学习的整合,二是对自下而上加工的强调。近几年,CLARION模型在理论和实践上都有较大进展。文章简要评述了CLARION模型,并围绕此模型介绍了学界有关内隐和外显加工交互作用的探索 相似文献

同步内隐/外显序列学习:事件相关的fMRI的初步研究 总被引:2,自引:1,他引:1
本文利用事件相关fMRI研究探讨对于内隐和外显学习在脑区激活上的差异.实验采用同步内隐/外显学习序列,以有色的形状作为刺激材料.要求被试对于刺激的颜色做选择反应,并在颜色消失后找出形状的内在规则.颜色和图形序列分别采用两个独立的马尔可夫链,即下一个图形的颜色或者形状有70%的可能服从序列规则.行为数据显示被试习得了外显和内隐的规则,fMRI成像主要比较内隐和外显学习在学习过程和知识运用上脑区激活的差异.结果发现,与内隐学习柑比,外显学习在额叶的激活更为显著.而且,内隐学习和外显学习在视觉皮层的激活出现分离,内隐学习中枕叶的激活减弱,而外显学习中枕叶的激活增加. 相似文献

序列长度和统计结构对序列位置内隐学习的影响 总被引:2,自引:0,他引:2
除人工语法之外,序列反应时任务也是内隐学习研究最常用的程式之一。在使用序列反应时任务进行内隐学习研究时,有研究者发现,类似于外显学习,序列位置内隐学习中序列规则的长度越长,学习成绩越差;而Stlader则在研究中发现,序列位置内隐学习中所学序列的统计结构会极大地影响被试内隐学习成绩,统计结构越高学习效果越好。 相似文献

Considerable research has been devoted to investigating learning without awareness. Burke and Roodenrys [Burke, D., & Roodenrys, S. (2000). Implicit learning in a simple cued reaction-time task. Learning and Motivation 31, 364–380] developed a simple learning task in which a cue shape predicts the arrival of a target shape (to which subjects respond) in a sequence of rapidly presented shapes, and found that all subjects responded faster to cued targets than to uncued targets, even those classified as unaware of the cue–target relationship. Two experiments were conducted to examine the perceptual flexibility of implicit (and explicit) learning using the paradigm developed by Burke and Roodenrys (2000). Perceptual flexibility was examined by altering the perceptual features of the cue shape. The results of the first experiment indicated the implicit, but not explicit, learning that occurs in this paradigm is perceptually inflexible. However, the second experiment indicated that perceptually flexible implicit learning can be encouraged by varying the nature of the experimental stimuli. These experiments therefore provide support for processing accounts of transfer. 相似文献

Over the last 20 years researchers have used the serial reaction time (SRT) task to investigate the nature of spatial sequence learning. They have used the task to identify the locus of spatial sequence learning, identify situations that enhance and those that impair learning, and identify the important cognitive processes that facilitate this type of learning. Although controversies remain, the SRT task has been integral in enhancing our understanding of implicit sequence learning. It is important, however, to ask what, if anything, the discoveries made using the SRT task tell us about implicit learning more generally. This review analyzes the state of the current spatial SRT sequence learning literature highlighting the stimulus-response rule hypothesis of sequence learning which we believe provides a unifying account of discrepant SRT data. It also challenges researchers to use the vast body of knowledge acquired with the SRT task to understand other implicit learning literatures too often ignored in the context of this particular task. This broad perspective will make it possible to identify congruences among data acquired using various different tasks that will allow us to generalize about the nature of implicit learning. 相似文献

Motor sequences are learned explicitly or implicitly based on conscious awareness of the sequence. Interference happens when two sequences are learned successively. Here, we aimed to determine whether implicit and explicit sequence learning are affected differently by retrograde interference. Young healthy volunteers participated in either a control or interference group and either an explicit or implicit learning condition. We used a modified serial reaction time task to induce sequence learning and control awareness. Results showed that the overall amount of sequence learning was greater in the explicit condition compared to implicit. However, sequence learning was equally susceptible to retrograde interference under either condition. We conclude that although susceptible to interference, explicit awareness improves overall sequence learning compared to implicit conditions. 相似文献

Implicit learning is one of the most fundamental learning mechanisms that enables humans to adapt to regularities inherent in the environment. Despite its high flexibility, it depends on constraints, such as selective attention. Here, we focused on the stimulus-to-response binding which defines the dimensions of the stimuli and the responses participants attend to. In a serial reaction time task with a visual sequence, we investigated whether this stimulus–response binding influences the amount of sequence learning. The results of Experiments 1 and 2 showed that visual sequence learning is reduced when participants do not attend to the relevant response dimension. Furthermore, the findings of Experiment 3 suggest that attention to the relevant response dimension increased the development of explicit knowledge without affecting implicit knowledge. This latter finding is difficult to reconcile with the assumption that explicit learning results from the gradual strengthening of sequence representations. 相似文献

Implicit sequence learning with competing explicit cues. 总被引:6,自引:0,他引:6
L Jiménez C Méndez 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》2001,54(2):345-369
Previous research has shown that the expression of implicit sequence learning is eliminated in a choice reaction time task when an explicit cue allows participants to accurately predict the next stimulus (Cleeremans, 1997), but that two contingencies predicting the same outcome can be learned and expressed simultaneously when both of them remain implicit (Jiménez & Méndez, 1999). Two experiments tested the hypothesis that it is the deliberate use of explicit knowledge that produces the inhibitory effects over the expression of implicit sequence learning. However, the results of these experiments do not support this hypothesis, rather showing that implicit learning is acquired and expressed regardless of the influence of explicit knowledge. These results are interpreted as reinforcing the thesis about the automatic nature of both the acquisition and the expression of implicit sequence learning. The contradictory results reported by Cleeremans are attributed to a floor effect derived from the use of a special type of explicit cue. 相似文献
