Assessing the influence of dimensional focus during situation model construction

According to Zwaan, Langston, and Graesser's (1995) event-indexing model, when comprehending text, readers monitor changes in a series of critical dimensions: space, time, protagonist, causality, and intentionality. In this study, the influence of dimensional focus was assessed during situation-model construction. Participants read narratives and were instructed to specifically monitor a single dimension while their sentence reading times were recorded. Critical sentence reading times were then analyzed for all shift types. Results support the general prediction that at least the time and protagonist dimensions are resistant to task demands, demonstrating that comprehenders routinely perform dimensional updating processes that are context independent. These results are discussed in the context of the event-indexing model.     

时间维度在记叙文理解中的作用

采用事件分割范式探讨了中文条件下时间维度在记叙文理解中的作用。实验1在中文条件下重复了Speer和Zacks(2005)年的研究,结果发现读者更多将时间短语所在位置作为分割边界,表明时间转换在情景模型更新中发挥了重要作用。实验2探讨了在没有时间短语条件下读者对文本分割的情况,结果发现读者主要是按照事件单元进行分割;实验3a和3b在文本的事件单元中插入时间短语,形成时间转换与事件转换分离的条件,探讨读者在这种时间转换与事件单元转换不一致的条件下所采用的分割策略,结果表明,读者更多仍然按照事件单元转换进行分割,而且对事件单元转换的依赖强于时间转换,但同时时间短语仍对文本的分割有一定影响。上述结果表明,事件单元作为建构记叙文心理表征的核心单元,时间维度作为事件单元转换的线索,只有在标识事件转换的情况下,才能引发读者情景模型的更新。     

记叙文阅读中主人公转换对情境模型更新的影响

应用探测任务范式和事件分割范式,以反应时、正确率、均字阅读时间等为指标,探讨主人公转换在记叙文情境模型更新中的作用。结果显示：（1）在主人公转换与事件转换一致时,主人公转换条件下的认知加工更加困难,表现为较长的反应时和均字阅读时间,以及较低的正确率和较高的分割概率。（2）在主人公转换与事件转换不一致条件下,主人公转换对反应时和均字阅读时间的影响显著降低,而分割概率与无转换条件无差异。这表明,事件是记叙文情境模型的核心;主人公维度仅在代表事件转换的条件下,才能引起情境模型的更新。     

路径转弯对语篇空间情境模型建构的影响

采用回指解决方法, 通过3个实验探讨了路径转弯对空间情境模型建构的影响机制。实验1和实验2的结果表明, 读者在建构含有路径转弯的语篇时, 在一定范围内出现了路径转弯效应。总体趋势为当语篇的空间描述简单(转弯次数<2)时, 目标句的阅读时间会随着转弯次数的增多而增长, 但当语篇的空间描述复杂(转弯次数>2)时, 不仅不再出现路径转弯效应, 反而出现了该效应的反转现象。实验3借助眼动仪监测, 运用语篇与主人公行走路线同步动态呈现模式, 让被试实时追随主人公行走路线, 控制转弯次数和路径距离, 以当前位置与回指地点间的直线距离为自变量, 探究读者在空间描述复杂时建构空间情境模型的心理机制。实验结果表明当阅读空间描述简单的语篇时, 读者建构的空间情境模型是路线型的, 通过逆向搜索的方式进行回指解决; 当语篇的空间描述较为复杂时, 读者倾向于建构地图型空间情境模型, 以俯视的视角通过空间搭桥寻找空间最短直线距离进行回指解决。     

情境模型中时间和空间维度更新的相互影响

运用移动窗口技术考察情境模型中时间和空间维度同时或序列转变时二者间的相互关系。结果发现：(1)时间和空间同时转变时, 二者存在易化关系, 但时间对空间的易化作用更大; (2)当二者序列转变时, 以中文为材料的结果只发现时间对空间的易化关系, 而以英语为材料的结果则发现存在双向易化关系, 但时间对空间的易化作用更大。据此, 情境模型中的时间和空间维度更新的捆绑－预期假设得到证明。     

Resolution of activated background information in text comprehension

The present experiments explored the resolution of activated background information in text comprehension. In Experiment 1, participants read passages that contained an elaboration section that was either consistent or qualified (inconsistent but then corrected to be consistent) with respect to the subsequently presented target sentence (see O'Brien et al., 1998). However, the experiment used two target sentences, and several filler sentences were inserted between the first and second target sentence. The results showed that the reading times for the first target sentence in the qualified elaboration version were significantly longer than those in the consistent elaboration version. These were consistent with O'Brien's study, and further indicated that the basic process captured by the memory-based view appears to generalize to the Chinese reader better than does the here-and-now view. More importantly, the results showed that the reading times for the second target sentence in the qualified elaboration version were as long as those in the consistent elaboration version. These further indicated that the activation of background information not only maintained the coherence of the text, but also allowed for the relevant information to be updated, resulting in a unified information set. When the information was reactivated during ongoing reading, it would be in the form of unified information. In Experiment 2, the first target sentence in each passage from Experiment 1 was converted to a filler sentence, and the second target sentence became the target sentence. The results of Experiment 2 showed that the reading times for the target sentence in the qualified elaboration version were significantly longer than those for the consistent elaboration version. These indicated that the delay between the target sentences and the elaboration section was not responsible for the lack of differences in Experiment 1, and confirmed the conclusion of Experiment 1.     

空间转换在记叙文阅读情境模型建构中的作用

采用探测词和事件分割范式探讨了空间转换与事件转换分离的情况下, 空间转换在记叙文情境模型建构中的作用。实验1a重复前人研究, 探讨空间转换对阅读时间和情境模型更新的影响, 并验证在空间转换对情境模型的影响的研究中, 采用多指标探测范式的合理性。实验1b探讨在空间转换与事件转换相分离的条件下, 空间转换对情境模型更新的影响; 实验2a探讨空间转换对事件分割的影响, 并验证在空间转换对情境模型的影响的研究中, 采用事件分割范式的合理性; 实验2b探讨空间转换与事件转换相分离的条件下, 空间转换对事件分割的影响, 从而验证空间转换对情境模型更新的影响。结果表明, 当空间转换与事件转换相分离时, 不引起情境模型的更新, 事件单元是建构记叙文心理表征的核心单元, 空间转换只有在标识事件转换的情况下, 才能引发读者更新情境模型。     

动词理解中空间表征的激活过程

探讨动词理解中空间表征的激活过程。被试听以不同空间轴向动词作谓语的句子后辨认视觉刺激的形状。实验1以肯定句为材料探讨语义理解对视知觉任务的影响。实验2以客观原因否定句为材料排除句子表征的影响。实验3以主观原因否定句为材料探讨动词空间元素的激活机制。总的结果表明,动词理解过程中激活其表征中的空间元素,这种激活是自动的、非策略性的,不受情境中客观原因或主观意愿否定的影响。动词理解空间效应反映了语言表征中的知觉运动特征     

文本阅读中空间距离的心理表征

采用学习探测模式和回指解决相结合的研究范式,探讨情境模型中空间距离的心理表征问题。实验1分离几何距离和类别距离,探讨类别距离对回指解决的影响。结果表明,在控制几何距离的条件下,读者采用由房间数目体现的类别距离信息建构情境模型;实验2进一步探讨几何距离的作用,结果发现,类别距离信息相同的条件下,读者在情境模型中表征几何距离信息。研究表明,类别距离和几何距离分别对空间情境模型的回指解决产生独立影响     

THE CONSTRUCTION OF SITUATION MODELS IN NARRATIVE COMPREHENSION:

Abstract— In this article, we propose and test a model of how readers construct representations of the situations described in simple narratives the event-indexing model. According to the event-indexing model, events are the focal points of situations conveyed in narratives and are connected in memory along five dimensions time, space, protagonist, causality, and intentionality. The results of a verb-clustering task provide strong support for the event-indexing model.     

文本阅读过程中信息的协调性整合

采用移动窗口阅读技术探讨文本阅读中信息的协调性整合问题。被试为华南师范大学本科生120名。实验材料按照主 人公特征与其目标句行为的关系总体上分为一致与恢复一致两个版本,每个版本都有两个目标句,出现在不同位置。实验1主 要探讨阅读过程中背景信息的激活与协调性整合的性质与特点,实验2主要探讨阅读过程工作记忆中前后信息的协调性整合 问题。采用相关样本t检验分别对两个目标句的阅读时间进行统计分析,结果发现,无论是通过共振激活的背景信息,还是保留 在工作记忆的文本信息,如果与新进入的文本信息有局部的不协调,那么就会产生协调性整合,整合的结果不仅维持了文本的连 贯,而且将相关的信息建构成整体的信息块     

文本阅读中协调性整合的条件

采用移动窗口阅读技术深入探讨文本阅读中协调性整合发生的条件。被试为华南师范大学一年级本科生。实验自变量是主人公特征与其目标句行为的关系,在实验一中有三个水平,一致、协调一致和恢复一致;在实验二中有两个水平,协调一致和恢复一致。实验一采用ANOVA对三种条件下目标句的阅读时间进行统计分析,结果表明,当前信息必须与先前的协调性信息有局部的不一致或不吻合是引发协调性整合的充分必要条件;实验二采用t检验分别对出现于不同位置的两个目标句的阅读时间进行统计分析,结果表明,协调性整合的结 果不仅维持了文本的连贯,而且将相关的信息建构成整体的信息块,文本阅读过程是一个包含流畅性阅读和以协调性整合为重要形式之一的整合性阅读的双加工过程。     

语篇理解中背景信息的激活: 情景限制的共振过程

该研究采用双人物线索语篇材料,对语篇理解中背景信息激活过程的共振模型与剧景模型进行检验。实验一发现,如果主角和配角一直同时在故事情景中成为主线索,则目标句中主角的行为可以激活那些经过屏蔽的、与这一行为相关的配角特征。在实验二中,配角只是在特征描述段落中出现,而后通过适当的描述使其在故事情景中消失,使主角成为故事的主线索,结果发现,此时目标句中主角的行为并不会激活经过屏蔽的配角的特征描述。这些结果表明,背景信息的激活虽然具有共振的特点,但共振并不是无范围限制的,而是一种情景限制下的共振。     

Discourse-based emotional consistency modulates early and middle components of event-related potentials

In this study, participants read stories describing emotional episodes with either a positive or negative valence (Experiment 1). Following each story, participants were exposed to short sentences referring to the protagonist, and the event-related potential (ERP) for each sentence's last word was recorded. Some sentences described the protagonist's emotion, either consistent or inconsistent with the story; others were neutral; and others involved a semantically anomalous word. Inconsistent emotions were found to elicit larger N100/P200 and N400 than consistent emotions. However, when participants were exposed to the same critical sentences in a control experiment (Experiment 2) in which the stories had been removed, emotional consistency effects disappeared in all ERP components, demonstrating that these effects were discourse-level phenomena. By contrast, the ordinary N400 effect for locally anomalous words in the sentence was obtained both with and without story context. In conclusion, reading stories describing events with emotional significance determines strong and very early anticipations of an emotional word.     

Tracking spatial information during reading: a cue-based process

The goal of the present set of experiments was to examine whether a cue-based mechanism could account for how, and under what conditions, spatial information is tracked. In five experiments, reading times were measured for a target sentence that contradicted the earlier-described location of a protagonist. When the target sentence contained either one or two cues to earlier spatial information (Experiments 1a-1c), reading times were disrupted. When all cues were eliminated (Experiments 2a and 2b), reading time were disrupted only when readers were instructed to take the perspective of the protagonist. The combined results of all five experiments are consistent with a cue-based mechanism: Readers encode spatial information but do not update earlier-encoded spatial information except in response to specific text characteristics (i.e., cues to earlier spatial information) or task demands (e.g., an instruction to read from the perspective of the protagonist) that increase the accessibility of earlier-encoded spatial information.     

What is minimal about predictive inferences?

Pronunciation of a probe word that relates to a highly predictable event is typically facilitated when the probe immediately follows the target sentence, but not when it is delayed until after a second sentence. These findings suggest that inferences about highly predictable events are minimally drawn during reading. Using a similar paradigm, in which the probe was delayed, we found significant priming in a reading condition that encouraged focus on the referential state of affairs (situation level) expressed in the sentences. In contrast, significant priming forpredictive texts was not observed in a reading condition that encouraged focus on the text per se (text level). These results are interpreted within a theoretical model that assumes that predictive inferences are represented at a situational level only, whereas explicitly presented information is represented at several levels (text and situational). It is in this sense that predictive inferences may be said to be minimally represented.     

Do readers mentally represent characters' emotional states?

Abstract

Subjects read stories that described concrete actions, such as a main character stealing money from a store where his best friend worked and later learning that his friend had been fired. Following each story, subjects read a target sentence that contained an emotion word that either matched the emotional state implied by the story (e.g. guilt) or mismatched that emotional state. In Experiment 1, target sentences were read more slowly when the mismatched emotion words were the perceived opposites of the emotional states implied by the stories (e.g. pride). In Experiment 2, target sentences were read more slowly when the mismatched emotion words shared the affective valence of the implied emotional state; therefore, readers must represent more than simply the affective valence of the emotional states. Instead of reading target sentences that contained matching versus mismatching emotion words, subjects in Experiment 3 simply pronounced matching versus mismatching emotion words. Mismatching emotion words were pronounced more slowly. These experiments suggest that readers form explicit, lifelike, mental representations of fictional characters' emotional states, and readers form these representations as a normal part of reading comprehension.     

Verb aspect and perceptual simulations

Two experiments investigate the influence of verb aspect on situation representations. The results demonstrate that comprehenders use verb aspect as a cue to regulate the activation of ongoing simulations of situations over time. Experiment 1 measured word-by-word reading as well as sensibility judgements on sentences in which a target object word had been replaced by a picture. For the past imperfective sentences, participants were faster to process the picture, the two words following the picture, and the sensibility judgements when objects were pictured in use rather than not in use. However, this in-use facilitation was limited to processing of the picture for the past perfect sentences. Experiment 2 served as a control to ensure that the use effect and its interaction with verb aspect were a result of contextual manipulations rather than surface features of the pictures themselves. The results are interpreted within the framework of perceptual simulations during language comprehension.     

Predictability of locomotion: Effects on updating of spatial situation models during narrative comprehension

We investigated how the updating of spatial situation models during narrative comprehension depends on the interaction of cognitive abilities and text characteristics. Participants with low verbal and visuospatial abilities and participants with high abilities read narratives in which the protagonist's motions in a fictitious building were either highly predictable or very hard to predict. In Experiment 1, high-ability readers updated spatial situation models only if the protagonist's motions were hard to predict, whereas low-ability readers did so only if the motions were highly predictable. In Experiment 2, facilitated integrative spatial processing compensated for the low-ability participants' resource limitations. As a result, both ability groups updated spatial situation models with hard-to-predict protagonist motions. These results highlight the interactions of cognitive abilities and text characteristics in spatial situation model updating.
