目标焦点监控下目标信息的建构与整合

探讨文本阅读过程目标焦点监控下读者对目标信息的建构与整合。采用移动窗口技术,要求被试阅读24篇含有主人公目标的记叙文,设计了子目标未实现、子目标曲折实现或子目标直接实现三种条件,对不同条件下目标启动句阅读时间进行分析。实验1对子目标曲折实现与子目标未实现两种条件下目标启动句阅读时间进行比较,结果表明,曲折实现条件下目标启动句阅读时间长于未实现条件下目标启动句的阅读时间,说明在没有共振的情况下,目标启动句也可以激活先前的目标信息引发目标整合。实验2比较在子目标曲折实现与子目标直接实现条件对目标启动句阅读时间,以探讨在目标焦点条件下是否对相关信息进行追随性建构,结果表明,曲折实现条件下目标启动句阅读时间与直接实现条件下目标启动句的阅读时间差异不显著,说明在目标焦点监控下可以发生阅读信息的追随性建构。本实验结果初步证明,阅读不同文本信息可能会引发不同的信息加工活动,建构主义理论与记忆基础文本加工理论都只是说明了文本阅读信息加工的一个侧面。     

汉字识别中的语音效应

该实验用启动掩蔽法探讨了汉字词识别中语音的作用。以五类高、低频汉字词对为材料,在三种启动时间条件下发现:高频形似音同目标字在25毫秒启动下有显著促进效应,而形异音同目标字在25和35毫秒有显著抑制效应。在低频情况下与上述相应的目标字表现出不显著的促进和抑制效应。此结果似乎表明汉字词识别过程具有程度不同的语音自动激活效应。     

负启动效应的抗抑制理论及其新进展

负启动效应及其机制是近年来认知心理学研究的重点课题。该文从情景提取说、短暂辨别说以及随意刺激—反应联结的自动化提取理论三个方面论述了负启动效应的抗抑制理论及其新发展,以期为进一步探讨负启动效应的形成机制提供帮助。     

归类任务中负启动效应与分心物特性抑制的实验研究

以汉语单字词为材料,采用负启动技术,在归类任务中考察了作为负启动效应根源的扩散抑制是否遵循资源有限机制以及在要求操作反应的情况下是否也能获得来自分心物特性抑制的负启动效应。结果表明：１．被试对曾在启动显示中作为分心物的探测目标的反应时随着启动显示中分心物数目的增加而缩短。因此,扩散抑制遵循资源有限机制;２．在操作反应要求下能获得非常显著的来自分心物特性抑制的负启动效应。     

掩蔽启动范式中的负相容效应——知觉阶段的交互还是反应阶段的抑制

掩蔽启动范式中, 当掩蔽刺激与目标刺激的时间间隔达到100~200ms时, 出现负相容效应。负相容效应是指相容条件的反应时大于不相容条件, 错误率高于不相容条件。目前主要有三种理论来解释负相容效应的发生机制, 分别是自我抑制理论、目标更新理论和掩蔽抑制理论。三种理论探讨了负相容效应发生的机制, 即负相容效应发生在知觉阶段还是反应阶段, 涉及自我引发抑制还是刺激引发抑制。有关负相容效应发生的机制还需进一步的探讨。     

注意转移在负相容效应产生中的作用:独立还是伴随*

采用两个实验设计,在确保负相容效应(NCE)的产生主要来自反应抑制贡献的实验范式基础上加入引发显性注意转移的目标刺激,探讨了注意转移在负相容效应产生中的作用。具体来说,实验一在经典NCE范式中加入中性目标刺激,并操纵启动与目标的关系。发现,不相容条件下的反应时最短,无关条件次之,相容条件下最长。证明在该范式中反应抑制在NCE的产生中占主导地位。实验二则在实验一范式的基础上,加入左、中、右呈现的加号目标刺激。发现,两种目标类型的反应时结果模式均与实验一相似。结果表明,注意转移并非如Cole和Kuhn(2010)提出的能够独立引发NCE,它只是伴随NCE的抑制加工过程而出现,且其加工模式与抑制加工模式类似。     

长时记忆中文本目标信息的激活机制

选取138名大学生被试,采用移动窗口实时阅读技术和探测技术,探讨文本理解过程中长时记忆的目标信息激活的机制。实验1探讨在中文条件下目标焦点是否也启动长时记忆中目标信息的整合。结果表明在目标实现的条件下,目标句1可以作为目标启动句,激活进入长时记忆中的目标信息。实验2和3探讨长时记忆中目标信息的激活是自然实现的还是需要目标愈合信号启动激活,实验结果表明长时记忆中目标信息的激活需要目标愈合信号的启动。该研究结果总的表明:阅读过程长时记忆中目标信息的激活不需要与当前阅读信息发生共振,目标愈合情境是影响长时记忆目标信息通达的关键因素。     

中文阅读过程中字形快速启动的眼动研究

以字形相似的汉字为启动字,探讨字形信息激活在汉字识别中的时间进程。实验1采用命名任务考察三种启动时间条件下是否存在字形启动效应,结果发现当启动时间为35ms时,出现稳定的字形启动效应。实验2采用眼动记录法考察阅读过程中的快速启动,结果在三种启动时间条件下均未发现显著的启动效应。     

汉字的特性负启动效应与年龄发展的关系

选用汉字材料,考察86名小学生、初中生、大学生和老年人被试特性负启动效应的产生情况.结果表明,特性抑制有一个从上升到衰退的过程;汉字同英文字母等材料一样可以发生显著的特性负启动效应;负启动效应是内隐的、不受意识控制的;特性负启动实验过程中的错误反应支持了注意的晚期选择模型.     

负相容效应中启动项-目标项关系对阈下信息加工的影响

采用掩蔽启动范式考察了负相容效应中启动项与目标项关系对阈下信息加工的影响,以及是否存在语义水平的负相容效应.两个实验分别以双箭头和汉字为掩蔽启动项,考察启动项和目标项重复、加工水平相同及加工水平不同三种条件下的启动效应.结果发现,两个实验的重复及加工水平相同条件下都出现负相容效应,且重复条件下启动量最大,加工水平不同条件下则无启动.这表明:(1)启动项与目标项的知觉重复影响启动量,但不是负相容效应的必要条件,只有当启动项和目标项加工水平相同时,才出现负相容效应;(2)存在语义水平上的负相容效应,阈下语义信息可得到加工并表现为对后继同类反应的抑制.     

Similarity information versus relational information: differences in the time course of retrieval

Two experiments are reported that examine the time course of retrieval in a sentence matching procedure. Subjects learned lists of active and passive sentences and were tested with sentences in active or passive, correct or incorrect versions; for example, if "John hit Bill" was a studied sentence, "Bill hit John" would be an incorrect active test sentence. A response signal procedure was used so that accuracy could be measured as a function of time. The data show that sentences containing words from studied sentences are discriminable early in processing from sentences containing all new words, but discrimination of correct from incorrect versions of studied sentences occurs only later in processing (after 600-700 ms). These results demonstrate that different kinds of information are available at different points during the time course of retrieval and so suggest that modifications are required of models that provide only a unitary value for the amount of match between a test probe and information in memory. Early in processing, the growth of accuracy can be explained by a simple model that assumes independent contributions to total amount of match for each of the content words of a sentence, but this independent processing model cannot account for discrimination later in processing. Several, more general, memory models are examined with respect to their abilities to produce independent item information early in processing and relational information later in processing.     

The bizarreness effect: evidence for the critical influence of retrieval processes

People show better memory for bizarre sentences relative to common sentences, a finding referred to as the bizarrness effect. Interestingly, this effect is typically only obtained using a mixed-list design, in which participants study common and bizarre sentences in the same list. This bizarreness effect in mixed-list designs has been explained as the result of both enhanced encoding processes and efficient retrieval processes. The present experiment was designed to isolate the unique contributions of the retrieval context to the bizarreness effect. Participants studied common sentences in one room under one set of instructions, and bizarre sentences in another room under another set of instructions. At test, participants recalled the common and bizarre sentences either together or separately. The results showed that the bizarreness effect was only obtained when participants recalled the common and bizarre items together; no bizarreness advantage emerged when participants were required to recall the common and bizarre items separately. These results suggest that differential encoding processes are not necessary for explaining the bizarreness effect in memory. Rather, retrieval of the mixed-list context appears to be critical for obtaining the effect.     

Disentangling encoding versus retrieval explanations of the bizarreness effect: Implications for distinctiveness

Recall effects attributed to distinctiveness have been explained by both encoding and retrieval accounts. Resolution of this theoretical controversy has been clouded because the typical methodology confounds the encoding and retrieval contexts. Using bizarre and common sentences as materials, we introduce a paradigm that decouples the nature of the encoding context (mixed vs. unmixed lists of items) from the retrieval set (mixed vs. unmixed retrieval sets). Experiment 1 presented unmixed lists for study, and Experiment 2 presented mixed lists for study. In both experiments, significant bizarreness effects were obtained in free recall when the retrieval set intermixed items but not when the retrieval set consisted of only one item type. Also, Experiment 1, using a repeated testing procedure, did not reveal evidence for more extensive encoding of bizarre sentences than of common sentences. The results support the idea that retrieval dynamics primarily mediate the bizarreness effect, and perhaps more generally, distinctiveness effects.

本研究通过分析任务态fMRI下相关脑区激活及功能连接的条件间差异以揭示CIEM神经基础并为心理模型更新及记忆提取失败假说提供更多证据。结果发现, 更正条件的推理分显著高于控制条件, 存在CIEM。编码阶段左颞中回在更正条件下的激活显著弱于控制条件, 提取阶段更正条件下额中回及前扣带回激活更弱、额中回与中央前回的功能连接更强。结果提示上述脑区可能参与了CIEM的形成, 并从神经层面提供了心理模型更新和记忆提取失败假说可能解释了CIEM形成的不同阶段的证据。     

Effects of making errors in learning a foreign language

ABSTRACT

Kornell, Hays, and Bjork ([2009]. Unsuccessful retrieval attempts enhance subsequent learning. Journal of Experimental Psychology: Learning, Memory, and Cognition, 35, 989–998) showed that incorrect guesses do not necessarily harm and might even improve the retention of information on a subsequent test. We sought to replicate the finding using educationally relevant stimuli. In two experiments, our participants either translated sentences in a foreign language receiving immediate feedback (errorful condition), or copied and studied the correct translation (errorless condition). After this training phase, a final test with the same sentences showed that translating sentences wrongly during training did not lower the accuracy of the errorful as compared to the errorless condition. Overall there was evidence that errorful training produced superior learning of the meaning and grammar of the foreign language sentences. The results support the idea that search processes activate a greater network of related knowledge in the errorful than in the errorless condition.     

Relational information in sentence memory

This paper is concerned with the coding and retrieval of relational or case information in sentences. Two experiments test the strong dependence hypothesis that relational information is checked in a secondary stage following the retrieval of facts from memory, where facts are retrieved on the basis of concept-overlap alone. In particular, memory for agent and object relational information in simple reversible sentences was investigated. The first experiment showed that relational information affected the reaction time and accuracy of the falsification of sentences that could have been rejected on the basis of content information alone. The second experiment approached the same issues using a recall procedure. It demonstrated the existence of some relational memory, even in the absence of any content recall. Both sets of data argued against the dependence hypothesis, but were compatible with the hypothesis that relational information is neither dependent on, nor secondary to, content information. The current findings and previous results concerning the impact of relational distinctions on interference effects are discussed in the context of the desirable properties of information retrieval systems.     

Proactive interference in sentence recall: Topic-similarity effects and individual differences

The effect of topic similarity on proactive interference in sentence recall was investigated in two experiments using the Brown-Peterson paradigm. In Experiment 1, successive sentences about the same topic and related topics were both associated with substantial and progressive amounts of proactive interference; however, a significant trials × condition interaction indicated that the effect was stronger in the related-topics condition. Moreover, significant negative correlations were found between individual differences in susceptibility to proactive interference and academic achievement test scores. In Experiment 2, relatively weak effects leveling off on the second trial were obtained with sentences about unrelated topics. With some assumptions about the spread of activation during retrieval, the results were attributed to response-set interference. The practical implications of these data were also considered, and it was suggested that proactive interference might be a common cause of learning problems.     

Retrieval-induced forgetting in recall and recognition of thematically related and unrelated sentences

In three experiments, we assessed the effects of type of relation and memory test on retrieval-induced forgetting of facts. In Experiments 1 and 2, eight sets of four shared-subject sentences were presented for study. They were constructed so that half were thematically related and half were unrelated. A retrieval practice phase required participants to recall a subset of the studied sentences. In the final test, the participants were prompted to recall all the sentences (character cued in Experiment 1 and character plus stem cued in Experiment 2). The results showed that the retrieval-induced forgetting (RIF) effect was similar for thematically related and unrelated sentences, indicating that the presence of episodic relations among the sentences was sufficient to produce the effect. In Experiment 3, a recognition task was introduced and the RIF effect emerged in accuracy as well as in latency measures. The presence of this effect with item-specific cues is difficult to accommodate for noninhibitory theories of retrieval.     

语境影响反语理解的眼动研究元分析

运用元分析的方法考察语境在反语理解中的作用及其相关的调节因素。通过文献检索,共搜集了13篇有效文献,16项实验数据,包含了806名被试。结果发现：(1)在反语理解正确率指标上反语明显比字面语更难理解,语境与目标反语不一致会产生额外推理过程,导致反语理解相对困难。(2)目标区反语和字面语在第一遍阅读时间指标上没有差异,但是在回视路径阅读时间和总阅读时间指标上反语的加工时间显著更长,这表明语境在反语加工的后期产生了作用,读者需要在加工后期对反语进行重新分析和整合,这一结果基本符合模块化理论的预测。(3)熟悉性对目标区的第一遍阅读时间和总阅读时间产生了调节作用,表明不管语境强度如何,熟悉的意义首先被加工,这一结果与分级显著性假设的预测基本一致。     

Semantic context influences memory for verbs more than memory for nouns

Three experiments revealed that memory for verbs is more dependent on semantic context than is memory for nouns. The participants in Experiment 1 were asked to remember either nouns or verbs from intransitive sentences. A recognition test included verbatim sentences, sentences with an old noun and a new verb, sentences with an old verb and a new noun, and entirely new sentences. Memory for verbs was significantly better when the verb was presented with the same noun at encoding and at retrieval. This contextual effect was much smaller for nouns. Experiments 2 and 3 replicated this effect and provided evidence that context effects reflect facilitation from bringing to mind the same meaning of a verb at encoding and at retrieval. Memory for verbs may be more dependent on semantic context because the meanings of verbs are more variable across semantic contexts than are the meanings of nouns.
