连贯阅读中文本表征的意识性研究

采用独立记得-知道范式(IRK)和加工分离范式(PDP)探讨连贯阅读中文本表征的意识性问题。实验1使用独立记得-知道范式(IRK),分析被试对再认项目判断为“记得”或“知道”的比例（击中率）;实验2使用加工分离范式(PDP),分析被试在包含、排斥测验中的击中率和虚报率。总的实验结果表明,在连贯阅读中,命题表征的建构是无意识的,情境模型的建构也是无意识的,该结果支持和完善了文本阅读双加工理论。     

焦点阅读中信息加工的意识性研究

采用独立记得-知道范式(IRK)和加工分离范式(PDP)探讨焦点阅读中文本表征的意识性。根据阅读材料中人物特征与其目标行为的关系,创设一致和恢复一致两种实验条件,实验1、2分别使用独立记得-知道范式,加工分离范式研究文本表征的意识性问题。研究结果发现被试在两种实验条件下的有意识加工和无意识加工指标上有显著差异,说明在焦点阅读中命题表征和情境模型的建构都是有意识的。     

说明文阅读中因果推理的意识性

采用独立记得-知道范式(IRK)和加工分离范式(PDP)探讨说明文阅读中因果推理的意识性。根据关系部分的描述与目标句是否存在逻辑冲突,创设推理成功和推理失败两种实验条件。实验1和2分别使用独立记得-知道范式和加工分离范式进行研究。两个实验的结果都发现推理成功和推理失败在有意识和无意识加工指标上都差异显著,表明说明文阅读中因果推理既影响有意识加工也影响无意识加工,该结果支持和完善了文本阅读双加工理论。     

文本阅读中文本表征的意识性研究

文本表征的意识性是文本阅读研究领域的一个新的热点问题,该问题研究的理论基础来自于多年以前研究者就提出的再认双加工模型,该问题研究的主要范式有记得-知道范式、独立记得-知道范式和加工分离范式,三者各有自己的特点,在很多研究中经常结合使用。当前,研究者使用最新的研究范式对文本阅读中文本表征的意识性进行了初步研究,已经初步得出了一些重要结论,但当前研究中仍存在一些问题,需研究者在未来的研究中加以关注。     

非自主闯入焦虑发生的机制：阈下启动效应的实验研究

本研究采用阈下情感启动范式, 研究威胁信息启动效应及其特质焦虑的调节作用,旨在揭示焦虑非自主闯入性特点形成的机制。实验在随机的三种条件下（阈上/阈下/基线）给38名被试呈现两种目标词（威胁词和中性词）,其中基线条件不呈现目标词;之后要求被试在回避目标词的条件下完成组词任务,结果：（1）无论是中性词还是威胁词,被试阈下条件下目标词的击中率显著高于基线条件;（2）特质焦虑对阈下启动效应起着调节作用：高焦虑组被试威胁词的启动效应显著高于中性词,低焦虑组被试中性词的启动效应显著高于威胁词。结论：阈下启动效应显著,高特质焦虑组个体对威胁信息的无意识加工会增强对威胁信息的意识加工,产生闯入性想法,导致焦虑非自主闯入性的特点。     

性别加工的记忆效应与内隐性别刻板印象

本研究以72名在校大学生为被试,采用心理过程分离程序,探讨了不同性别加工学习条件下被试的记忆效果。实验结果表明：在两性角色行为特征的认知过程中,意识过程和无意识过程对记忆效果的影响是不同的。有意识的外显记忆效果,两种条件无显著差异;但在无意识的内隐记忆效果上差异显著,反映了一种对女性另眼相看,严格苛求的内隐性别刻板印象。     

有多少记忆可以内隐——兼评Jacoby加工分离程序

自从1991Jacoby使用简单的再认任务分离出意识性提取与无意识熟悉性以来,虽然PDP的计算范式也受到一些修正,但均没有在计算范式的内核思想上改进过,只是PDP延伸出的应用研究非常多。其实,Jacoby在构建PDP范式时,从描述PDP的心理现象、构建数学模型到PDP在实践中的应用上均出现了重大失误。本研究从上述三个方面对PDP提出了质疑,使用集合模型重新构建了PDP计算模型,用实验验证了PDP新模型,纠正了Jacoby理论与应用的三大错误。     

不同意识水平下的情绪启动

实验研究了不同意识水平下情绪启动的机制。我们采用带有褒贬意义的中文语句作为情绪刺激,要求被试在情绪刺激播放响度正常或极低的情境下对不熟悉的法语语句进行评价。结果显示无意识情绪启动显著;有意识情绪启动却未出现。我们认为无意识情绪启动是个体对刺激自动加工的结果;而个体在意识层面的认知加工可能会抑制已唤醒的情绪。另外,情绪刺激的不同排列方式对被试评价的倾向性可能有潜在的影响。     

PDP启动型实验程序与Richardson-Klavehn模型的比较研究

2个实验对PDP的启动型实验程序与Richardson-Klavehn的修正模型进行了比较研究,通过对指示语的操纵,考察提取策略是否完全受意志控制,以及注意水平、刺激材料、测验类型、加工水平对被试作业的影响.结果发现刺激材料对有意识控制记忆的实验结果影响很大,对PDP的无意识自动加工参数无影响;启动型实验程序的结果与PDP理论相当一致;提取策略不一定是受意志精确控制的.     

无意识加工对创造性问题解决的促进效应

以远距离联想测验(RAT)和字谜作为实验材料,采用改进的掩蔽启动实验范式,探讨无意识加工对创造性问题解决的影响。结果发现:(1)无论是完成远距离联想任务还是字谜任务,被试在启动和无启动条件下的正确率均无显著差异;(2)在两类任务下,对于高难度的创造性问题,启动条件下的正确率显著高于无启动条件。对于低难度的创造性问题,启动条件下RAT的正确率显著低于无启动条件,字谜的正确率在两种条件下无显著差异;(3)随着创造性问题难度降低,无意识信息的促进效应逐渐减小,对于低难度的创造性问题,无意识信息反而会起到抑制作用。这表明,无意识加工对随后的创造性问题解决过程具有促进效应,而且这种效应只有在解决高难度的创造性问题时才会体现。     

Assessing text representations with recognition: The interaction of domain knowledge and text coherence

Readers construct at least 2 interrelated mental representations when they comprehend a text: a textbase and a situation model. Two experiments were conducted with recognition memory to examine how domain knowledge and text coherence influence readers' textbase and situation-model representations. In Experiment 1, participants made remember-know judgments to text ideas. Knowledge and coherence interacted to influence remember judgments differently than know judgments. In Experiment 2, the authors used the process-dissociation procedure to obtain recollection and familiarity estimates. Knowledge and coherence interacted to influence recollection estimates but not familiarity estimates. The authors claim that recollection and familiarity can be used as markers of the different processes involved in constructing a textbase and a situation model.     

年老化与文本理解

年老化与文本理解的研究表明,老年人在表层形式和文本基础两个低水平表征上的理解和记忆能力下降,而在情境模型的建构和提取、更新等加工过程中都没有发现由于年老化引起的能力下降。在介绍这些研究的基础上,从情境模型与另两个低水平加工的不同特点和老年人自身的特殊性两个方面分析了老年人在不同层次表征水平加工能力差异的原因。对情境模型水平加工能力保持的潜在机制及相关的影响因素,以及如何弥补在低水平加工中认知能力因年龄而产生的下降等问题还需要进行探讨     

Learning From Text

A framework is presented for distinguishing between two types of mental representations formed while reading a text: The textbase is a representation built in the process of comprehension, and a situation model is built to represent the situation described in the text. Two studies are reported that explore the relative contribution of each type of representation and their interaction during problem solving. In the first, grade school children solved easy and hard arithmetic word problems of three types: change, combine, and compare. When asked to recall, reconstruction of the problems occurred and was related to solution performance. Children tended to recall problems already solved on the basis of the situation model used in solutions and not by reproducing the original textbase. In the second study, college students formed mental maps while reading two types of texts describing the layout of a town: The survey text described the town in geographical terms, and the route version presented the same information as a series of instructions for driving through the town. A dichotomy was seen between remembering the text and learning from it; the former was dependent on text coherence, and the latter depended on the formation of a situation model. Implications for instruction are discussed in terms of clarifying goals for the use of texts and distinguishing between instruction aimed toward recall and instruction aimed toward learning.     

Age differences in learning from text: Evidence for functionally distinct text processing systems

We investigated the influence of sentence elaboration on self‐regulated learning in order to examine age differences in resource allocation to the construction of textbase‐ and discourse‐level representations. Older and younger adults learned about a topic by reading a series of sentences varying in elaboration (from simple factoids to highly elaborated text) and manner of presentation (progressive change in elaboration vs. random change in elaboration). Younger readers were more likely to recall information from factoids; older adults, from highly elaborated text. Relative to young, older readers showed an advantage in the progressive presentation condition, which minimised frequent changes between textbase‐ and discourse‐level processing. Older adults showed poorer memory monitoring for factoids and less elaborated discourse relative to young, but when passages were highly elaborated or presented progressively, age differences were eliminated. Results support the idea that textbase‐ and discourse‐level encoding arise from functionally distinct systems whose regulation depends on text properties and reader age.

Retrieving text inferences: Controlled and automatic influences

Bridging inferences contribute to text coherence by identifying the connections among ideas, whereas elaborative inferences simply specify sensible extrapolations from text. Bridging inferences have been indistinguishable from explicit text ideas on numerous measures, suggesting similar longterm memory (LTM) representations for the two, whereas elaborative inferences are inferior. To evaluate the LTM representations of text ideas, we used the extended process-dissociation procedure (Buchner, Erdfelder, & Vaterrodt-Plunnecke, 1995; Jacoby, 1991) to partition the controlled, recollective contributions to text retrieval from the automatic, familiarity-based contributions. The automatic contribution to the recognition of implied concepts was consistently negligible, an outcome consistent with the absence of perceptual processing of those concepts during the original reading. In addition, the controlled basis of recognition was consistently higher for explicit than for implicit concepts, which suggests a more robust conceptual representation for explicit text ideas (Yonelinas, 2002). These results were interpreted to reflect the asymmetric representation of explicit ideas and inferences (elaborative and even bridging inferences) in the surface, propositional textbase, and situational levels of text representation.     

Re-Examining the Effect of Top-Down Linguistic Information on Speaker-Voice Discrimination

The current study replicated and extended the results from a study conducted by Narayan, Mak, and Bialystok (2017) that found effects of top-down linguistic information on a speaker discrimination task by examining four conditions: rhymes (day-bay), compounds (day-dream), reverse compounds (dream-day), and unrelated words (day-bee). The original study found that participants were more likely to judge two words to be spoken by the same speaker if the words cohered lexically (created lexical compounds such as day-dream) or were phonologically related (rhymes, such as day-bay), but their study contained two limitations: (a) Same- and different-speaker trials were analyzed separately, which obscures effects of response bias, and (b) cross-gender pairs were used in the different-speaker trials, potentially inflating performance. The current study addresses these limitations by including only within-gender trials and by examining sensitivity and bias using signal detection theory. Our results not only provide support of the original study but also provide clear evidence that listeners are biased to judge two words as being produced by the same person when they share either phonological information (rhymes) or lexical-semantic coherence (compounds). Thus, the current study provides an important modified replication of previous research.     

Age differences in rereading

Younger and older adults read a series of expository and narrative passages twice in order to answer comprehension questions. Reading time was used to index attentional allocation to word, textbase, and situation model processing and to assess shifts in the allocation policy from the first to the second reading. Older readers' comprehension was at least as good as that of younger readers. Analysis of reading times suggested that for both genres, older adults allocated more attention to situation model features than younger adults did on the first reading, whereas young and old allocated attention similarly to this level of representation on the second reading, suggesting that mature readers may give greater priority to situation model construction when first encountering text. Also, for both genres, older adults showed relatively less facilitation than the young in word-level processing in rereading, suggesting that representation at this level is not as firmly established during reading or decays more quickly for older readers. For narrative texts only, this pattern also obtained for textbase processing. Collectively, these data show that age equivalence in text comprehension at the molar level may be accomplished through different processing routes at the molecular level.     

Self-regulated reading in adulthood

Young and older adults read a series of passages of 3 different genres for an immediate assessment of text memory (measured by recall and true/false questions). Word-by-word reading times were measured and decomposed into components reflecting resource allocation to particular linguistic processes using regression. Allocation to word and textbase processes showed some consistency across the 3 text types and was predictive of memory performance. Older adults allocated more time to word and textbase processes than the young adults did but showed enhanced contextual facilitation. Structural equation modeling showed that greater resource allocation to word processes was required among readers with relatively low working memory spans and poorer verbal ability and that greater resource allocation to textbase processes was engendered by higher verbal ability. Results are discussed in terms of a model of self-regulated language processing suggesting that older readers may compensate for processing deficiencies through greater reliance on discourse context and on increases in resource allocation that are enabled through growth in crystallized ability.
