应当关注时间心理无意识的研究

随着心理无意识研究在记忆、学习和思维等领域的兴起,内隐时间认知也逐步成为时间心理学中的一个研究热点。本文分析了探究内隐时间认知的四种方法:分离范式、序列学习范式、表征动量范式和计时分布相关范式,指出内隐时间认知实验范式在无意识时间人格与社会心理学中的研究也是有相当前景的。     

自闭症儿童的内隐学习假说：来自人工语法学习的证据

由于自闭症的症状和个体的内隐学习都主要涉及语言领域,研究者提出了内隐学习假说,认为自闭症症状可能部分来自于内隐学习缺陷。然而,目前的研究尚未得出一致的结论。该研究采用人工语法学习范式和无意义的汉字串材料,并严格控制材料的组块特征,考察了一般的自闭症儿童、年龄匹配的普通儿童以及年龄和智商匹配的智障儿童的内隐学习。结果发现：（1）普通儿童和智障儿童的内隐学习成绩都显著高于随机水平,表明他们能够内隐习得语法规则;（2）自闭症儿童的内隐学习成绩与随机水平没有显著差异,同时与两组对照组儿童的成绩也没有显著差异。这可能意味着,自闭症儿童语法规则的内隐学习既存在缺陷、又有所保留。该研究为自闭症儿童的内隐学习假说提供了新的来自语言领域的证据。     

内隐学习抽象性研究的新进展

以知识迁移作为内隐学习抽象性众多涵义的统领点,同时结合国内外多领域内隐学习的新近研究,以一些详实的实征研究从一个新视角对其作了进一步的诠释,旨在更好地体现内隐学习的抽象性及其巨大潜力。     

试析内隐学习的材料敏感性

在人工语法范式、序列反应时任务范式以及复杂系统控制任务范式中，内隐学习对学习材料的难度及复杂度、材料性质、材料呈现方式等较为敏感。具体表现为难度和复杂程度较高的学习材料，以及形象性较突出的学习材料，更适合内隐学习，而使材料结构特点变得明显的呈现方式不利于内隐学习。然而，内隐学习的材料敏感性在其它范式上的普遍性有待进一步的实验研究。     

内隐学习本质特征的实验研究

本实验以人工语法范式的常规模式和Reber语法的一个变式对内隐与外显学习进行了分离,采用的手段为记忆指导语与规则发现指导语。此外,我们还增添了字母集变量以了解内隐学习的抽象性,及时间变量(单元)以推测内隐学习的理解性。通过本实验,我们再次证明了内隐学习的自动性,初步验证了内隐学习的抽象性、间接测得了内隐学习的理解性。

内隐学习和无觉察知觉辨析

在无意识研究的热潮中,无觉察知觉、内隐学习相继得到很大发展。这两种认知过程都涉及到无意识加工,相互之间有非常密切的联系。本文介绍了这两种无意识加工过程,并对其联系、区别进行了辨析。     

试析内隐学习的意识-无意识兼容性

内隐学习研究初期,其无意识特点揭示了区别于外显学习的独特本质。但随着研究的深入,内隐学习逐渐昭显出与意识的丝丝联系。本文从此出发,探讨内隐学习的意识-无意识的兼容特点,具体从理论和实证两方面探讨内隐学习和无意识的联系,从次要任务研究、内隐学习的理解性以及内隐知识的发展三方面阐述内隐学习和意识的联系。

通观自1967年内隐学习诞生以来三十余年的研究状况,结合人工语法范式研究者的典型实验,分别从四个侧面(从外部到内部、从简单到复杂、从分离到协同、从理论到应用)介绍了内隐学习研究的历程,并夹叙夹议地展开讨论,启示人们关注这一领域.     

嵌套范式下视空工作记忆对基于规则类别学习

基于COVIS模型与认知加工阶段假设,通过2个实验探讨嵌套范式下, 视空工作记忆对基于规则类别学习的影响。实验1采用类别学习中嵌套视空工作记忆的范式,结果发现视空工作记忆削弱基于规则类别学习成绩,与COVIS模型预测相一致。实验2则采用视空工作记忆中嵌套类别学习任务的范式,结果却发现视空工作记忆对基于规则类别学习的影响消失。实验结果表明嵌套范式下视空工作记忆的位置影响基于规则类别学习,初步验证了类别学习存在多个认知加工阶段的假设,视空工作记忆主要影响基于规则类别学习中规则的发现和检验阶段。     

The Interplay of Cross‐Situational Word Learning and Sentence‐Level Constraints

A variety of mechanisms contribute to word learning. Learners can track co‐occurring words and referents across situations in a bottom‐up manner (cross‐situational word learning, CSWL). Equally, they can exploit sentential contexts, relying on top–down information such as verb–argument relations and world knowledge, offering immediate constraints on meaning (word learning based on sentence‐level constraints, SLCL). When combined, CSWL and SLCL potentially modulate each other's influence, revealing how word learners deal with multiple mechanisms simultaneously: Do they use all mechanisms? Prefer one? Is their strategy context dependent? Three experiments conducted with adult learners reveal that learners prioritize SLCL over CSWL. CSWL is applied in addition to SLCL only if SLCL is not perfectly disambiguating, thereby complementing or competing with it. These studies demonstrate the importance of investigating word‐learning mechanisms simultaneously, revealing important characteristics of their interaction in more naturalistic learning environments.     

学习因素对语义信息加工性质的影响

本研究通过两个行为实验,采用句子核证作业,将SAD技术和范畴学习范式有机地结合起来,对语义信息加工进程以及学习因素在其中的作用进行了考察。实验一研究了熟悉性对语义信息加工的影响。结果表明,高熟悉句的部分信息积累具有离散的趋势;低熟悉句的部分信息积累是连续性的。实验二采用范畴学习。并结合SAD技术的句子核证作业．考察了在学习过程中语义加工性质的变化。结果发现：过度学习比初始学习有更多的部分信息积累,并随信号间隔的延长而逐渐增加;过度学习表现出部分信息积累的离散性变化;初始学习则表现出连续累积的趋势。说明学习确实造成了连续性加工向离散性质的过渡。     

Only the right noise? Effects of phonetic and visual input variability on 14‐month‐olds' minimal pair word learning

Seminal work by Werker and colleagues (Stager & Werker [1997] Nature, 388, 381–382) has found that 14‐month‐old infants do not show evidence for learning minimal pairs in the habituation‐switch paradigm. However, when multiple speakers produce the minimal pair in acoustically variable ways, infants' performance improves in comparison to a single speaker condition (Rost & McMurray [2009] Developmental Science, 12, 339–349). The current study further extends these results and assesses how different kinds of input variability affect 14‐month‐olds' minimal pair learning in the habituation‐switch paradigm testing German learning infants. The first two experiments investigated word learning when the labels were spoken by a single speaker versus when the labels were spoken by multiple speakers. In the third experiment we studied whether non‐acoustic variability, implemented by visual variability of the objects presented together with the labels, would also affect minimal pair learning. We found enhanced learning in the multiple speakers compared to the single speaker condition, confirming previous findings with English‐learning infants. In contrast, visual variability of the presented objects did not support learning. These findings both confirm and better delimit the beneficial role of speech‐specific variability in minimal pair learning. Finally, we review different proposals on the mechanisms via which variability confers benefits to learning and outline what may be likely principles that underlie this benefit. We highlight among these the multiplicity of acoustic cues signalling phonemic contrasts and the presence of relations among these cues. It is in these relations where we trace part of the source for the apparent paradoxical benefit of variability in learning.     

Reflecting talks: a pedagogical model in the learning organization

The aim of the article is to deepen the understanding of how a pedagogical model for reflecting talks can be used in order to make sustainable learning part of the daily work in the learning organization. From an interactive research approach, we have together with a project management group in a European Social Fund project worked with sustainable learning and knowledge development. Empirical data has been collected at the implementation of ten reflecting talks about sustainable equality. The results of the study lead to a strategy for how sustainable learning can become part of the daily work at a workplace. The strategy is constituted by a pedagogical model for reflecting talks, which clearly shows how sustainable learning in an organization can be structured. The core of the pedagogical model for the reflecting talks where both practically applied and theoretically anchored knowledge are important components. The learning process is based on observation, reflection, analysis and discussion of concrete situations/events. The models rests on four basic conditions; pedagogical competence, a delimited problem area, the learning group and timeframes. The model can be used in the daily work at short dialogues or at more penetrating discussions.

人工语法学习中意识加工的渐进发展

内隐学习研究致力于探讨学习活动的意识加工程度, 当前相关的研究逻辑从传统的意识二分观转向渐进意识假设。本研究通过对人工语法范式进行改造, 并借鉴加工分离程序的有关思想, 在学习阶段引入双重测量任务, 并根据双重任务成绩计算分离出相应学习时段的意识与无意识成分的贡献分数, 从而考察在内隐学习过程中两种加工成分的动态变化特征。研究结果支持渐进意识假设, 在学习进程中, 无意识成分和意识成分都呈现出渐进发展的趋势; 而随学习的深入, 两种成分呈现出不同的变化模式, 中后期意识加工快速增长, 无意识加工则保持平缓发展, 渐进意识系统整体呈现向外显学习推进的发展态势。     

Learning times for large lexicons through cross-situational learning

Cross-situational learning is a mechanism for learning the meaning of words across multiple exposures, despite exposure-by-exposure uncertainty as to a word's true meaning. Doubts have been expressed regarding the plausibility of cross-situational learning as a mechanism for learning human-scale lexicons in reasonable timescales under the levels of referential uncertainty likely to confront real word learners. We demonstrate mathematically that cross-situational learning facilitates the acquisition of large vocabularies despite significant levels of referential uncertainty at each exposure, and we provide estimates of lexicon learning times for several cross-situational learning strategies. This model suggests that cross-situational word learning cannot be ruled out on the basis that it predicts unreasonably long lexicon learning times. More generally, these results indicate that there is no necessary link between the ability to learn individual words rapidly and the capacity to acquire a large lexicon.
