Offline consolidation supersedes prior knowledge benefits in children's (but not adults’) word learning

Prior linguistic knowledge is proposed to support the acquisition and consolidation of new words. Adults typically have larger vocabularies to support word learning than children, but the developing brain shows enhanced neural processes that are associated with offline memory consolidation. This study investigated contributions of prior knowledge to initial word acquisition and consolidation at different points in development, by teaching children and adults novel words (e.g., ballow) that varied in the number of English word‐form “neighbours” (e.g., wallow, bellow). Memory for the novel word‐forms was tested immediately after training, the next day and 1 week later, to assess the time‐course of prior knowledge contributions. Children aged 7–9 years (Experiments 1, 3) and adults (Experiment 2) recalled words with neighbours better than words without neighbours when tested immediately after training. However, a period of offline consolidation improved overall recall and reduced the influence of word‐form neighbours on longer term memory. These offline consolidation benefits were larger in children than adults, supporting theories that children have a greater propensity for consolidating phonologically distinctive language information. Local knowledge of just a single word‐form neighbour was enough to enhance learning, and this led to the individual differences in word recall that were related to adults’ global vocabulary ability. The results support the proposal that the relative contributions of different learning mechanisms change across the lifespan, and highlight the importance of testing theoretical models of word learning in the context of development.     

试论内隐学习的多水平动态观

文章回顾了关于内隐学习意识性的实证研究和理论探讨。在此基础上,借助Karmiloff—Smith的表征重述概念,构建了一个多水平觉察状态、多水平表征机制、多水平能量需求的内隐学习机制动态观。该观点不同于以往对内隐学习的静态分析,揭示了内隐学习和外显学习在机能上的连续性,     

非文字内隐学习的优势效应

本研究以大学生为被试,运用计算机将人工语法范式程序化,分别以色块串和色词串为材料,研究颜色内隐和外显学习的特点;并增设时间变量（单元）以了解学习的详细进程。结果发现：1.学习材料上存在主效应,非言语材料（包块）较言语材料（色词）更适合于内隐加工。2.时间变量上也存在主效应,整体呈递增趋势;3.指导语上不存在主效应,即内隐学习在不同材料上的优势效应依然存在。实验结果极好地支持了非文字内隐学习优势效应的假设。     

初一学生英语单词记忆策略的训练研究

在初一学生英语单词学习中引入关键词和概念归类策略训练,探讨了记忆策略的训练效果和自我效能对英语单词记忆的影响。结果发现：两种策略训练都能显著提高初一学生英语单词扇一效果相近;关键词策略训练可显著提高低自我效能被试的自我效能感;记忆自我效能对英语单词记忆行为有显著影响,高自我效能被试在训练后英语单词记忆成绩更好。     

多面体的一面:第二语言学习的社会化过程

第二语言学习过程是社会互动情景中的言语活动,"热"的社会化过程是第二语言学习过程的有机组成部分;形成第二语言情景下的文化心理参照系认知能力和文化适应能力是第二语言的言语能力重要内容;第二语言学习过程中的言语变异现象部分源于学习者的社会心理结构特征。     

重复学习判断中的低自信效应

学习判断是元认知判断的一种重要形式,是对未来回忆成绩的预测。重复学习判断中的低自信效应是一个有趣而反常的现象,指在重复学习测验中,学习判断往往低估了回忆成绩的增加,出现低自信的一种现象。目前,大部分实验证据支持重复学习判断中的低自信效应是普遍存在的,但也有一些实验结果表明该效应是受一定条件限制的。对于这种低自信效应的作用机制,研究者提出了不同的理论模型（如,锚定调整假说、记忆偏向消除理论、过去测验记忆的启发式假说等）进行了深入探讨。最后,文章还指出了此领域现有研究的局限和有待研究的问题     

Persistent structural priming from language comprehension to language production

To examine the relationship between syntactic processes in language comprehension and language production, we compared structural persistence from sentence primes that speakers heard to persistence from primes that speakers produced. [Bock, J. K., & Griffin, Z. M. (2000). The persistence of structural priming: transient activation or implicit learning? Journal of Experimental Psychology: General, 129, 177-192.] showed that the production of target priming structures increased the probability of spontaneously using the same structures to describe events in subsequent pictures that were semantically unrelated to the primes. These priming effects persisted across as many as ten intervening filler trials. The present studies replicated these results using auditorily presented primes to which participants only listened. The results indicated persistence of priming across all lags, with relative magnitudes of priming as large as those observed by Bock and Griffin. The implication is that structural priming is persistent regardless of the modality in which language structures are experienced, underscoring the power of priming as an implicit learning mechanism.     

Perceptual constraints and the learnability of simple grammars

Cognitive processes are often attributed to statistical or symbolic general-purpose mechanisms. Here we show that some spontaneous generalizations are driven by specialized, highly constrained symbolic operations. We explore how two types of artificial grammars are acquired, one based on repetitions and the other on characteristic relations between tones ("ordinal" grammars). Whereas participants readily acquire repetition-based grammars, displaying early electrophysiological responses to grammar violations, they perform poorly with ordinal grammars, displaying no such electrophysiological responses. This outcome is problematic for both general symbolic and statistical models, which predict that both types of grammars should be processed equally easily. This suggests that some simple grammars are acquired using perceptual primitives rather than general-purpose mechanisms; such primitives may be elements of a "toolbox" of specialized computational heuristics, which may ultimately allow constructing a psychological theory of symbol manipulation.     

On teaching psychoanalysis

Teaching psychoanalysis is no less an art than is the practice of psychoanalysis. As is true of the analytic experience, teaching psychoanalysis involves an effort to create clearances in which fresh forms of thinking and dreaming may emerge, with regard to both psychoanalytic theory and clinical practice. Drawing on his experience of leading two ongoing psychoanalytic seminars, each in its 25th year, the author offers observations concerning (1) teaching analytic texts by reading them aloud, line by line, in the seminar setting, with a focus on how the writer is thinking/writing and on how the reader is altered by the experience of reading; (2) treating clinical case presentations as experiences in collective dreaming in which the seminar members make use of their own waking dreaming to assist the presenter in dreaming aspects of his experience with the patient that the analytic pair has not previously been able to dream; (3) reading poetry and fi ction as a way of enhancing the capacity of the seminar members to be aware of and alive to the effects created by the patient's and the analyst's use of language; and (4) learning to overcome what one thought one knew about conducting analytic work, i.e. learning to forget what one has learned.     

序列位置内隐学习产生机制的实验研究

内隐学习是当今认知和学习领域继内隐记忆之后又一重要的研究课题。该研究利用序列反应时研究程式,通过两个实验,对序列位置内隐学习产生的机制进行了探讨。结果表明：（１）在序列反应时任务程式中,随着反应一刺激间隔的延长,序列位置内隐学习的学习量逐渐减少;（２）异形同模式迁移组和异形异模式迁移组被试间内隐学习量无显著差异,被试未能内隐地习得抽象的序列模式。说明序列位置内隐学习产生的基础是水平联结,在该实验条件下没有发现垂直联结存在的证据。
