话题结构对语篇情绪累加的影响

在阅读理解的过程中,读者能够自动对语篇中的情绪进行推断。本研究采用自定步速阅读的方法,分别在外显和内隐两种情绪加工的任务下,考察话题结构对语篇情绪累加的影响。结果发现,在实验一的外显情绪判断任务下,话题结构未显示出对语篇情绪累加的明显作用;在实验二的内隐情绪理解任务下,当话题延续时,读者对有两个情绪线索的语篇的阅读时间短于仅有一个情绪线索的语篇,此时情绪的累加促进了当前句的加工,而话题转换时,二者没有显著差异,说明此时读者在新结构下建立当前句的情绪表征,并不在先前情绪的基础上进行累加。     

主角情绪和时间信息对情境模型加工的影响

采用移动窗口技术探讨了情境模型加工中主角情绪与时间转换因素对情境模型加工的影响。实验1采用单因素被试内设计, 结果显示, 关键句的阅读时间模式为：放松-放松=担心-放松<放松-担心=担心-担心。实验2采用4×2两因素被试内设计, 结果在担心-担心模式下大的时间转换比小的时间转换的阅读时间长, 而时间转换因素对于主角情绪状态是担心-放松、放松-放松和放松-担心模式的加工没有影响。实验结果表明, 读者在阅读语篇时实时追踪主角的情绪状态, 出现了部分的情绪转换效应。阅读中读者体验到的积极的情绪状态有利于情境模型的建构, 相反, 体验到的消极的情绪状态会妨碍情境模型的建构。时间转换因素在一定程度上影响了对主角情绪状态的加工, 主角担心-担心的情绪状态在大的时间转换条件下, 前后两种相同的消极情绪可能会产生一种叠加效应, 使读者的情境模型加工更加困难; 而在小的时间转换条件下, 读者对从放松转向担心的情绪状态的加工会花费更多的认知资源。     

自闭症儿童对情景事件的情绪理解：基于内隐和外显的测量

该研究旨在采用生态效度更高的情绪情景事件以及内隐和外显两种测量方式考察自闭症儿童的情绪理解。选取自闭症和智商匹配的正常儿童各21名,以序列图片的方式呈现从动画片中截取的不同效价的情景事件,外显任务要求被试直接判断事件主角的情绪、内隐任务要求被试判断事件的一致性。结果发现：1.在外显任务中,自闭症儿童对正性和负性情绪的判断正确率均显著不如正常儿童,尤其是在负性情绪上存在明显的理解缺陷;2.在内隐任务中,正常儿童的正性负性情绪、自闭症儿童的正性情绪都表现出更弱的相对于中性情绪的理解效应;自闭症儿童的负性情绪理解则在两种任务中都接近于无。这些结果意味着自闭症儿童在外显和内隐任务中都存在负性情绪理解缺陷。

语篇情绪理解及其认知神经机制

在心理语言学领域,情绪信息加工是语篇理解的重要方面,得到了广泛关注。目前的研究表明,读者在语篇阅读中可以在线地、自动地推测出语篇情绪信息,追踪情绪信息的变化,并对其进行更新。语篇理解相关的模型及一些事件相关电位(ERP)的实证研究表明语篇情绪理解至少包括两个重要的加工过程:一是对语篇情绪信息的实时监控,二是对当前情绪信息的评估与更新。相关的功能磁共振(f MRI)的研究表明语篇情绪理解除了需要经典的情绪加工网络,还需要多个脑区网络的参与,如,语篇理解网络、心理理论(To M)网络。未来研究还需更加深入地、更加细致地探讨语篇情绪理解的认知神经机制及其可能的影响因素,研究成果也可以为情感计算领域提供一定的借鉴。     

内隐/外显不同水平攻击者的注意偏向：行为和ERP证据

通过行为实验（点探测）和ERP实验（情绪Stroop）两个实验任务,考察了内隐/外显不同水平攻击者的注意偏向及其脑机制。结果表明：高外显攻击者对愤怒面孔存在注意偏向;高外显攻击者在愤怒面孔上的N100波幅显著低于中性面孔,表明其注意分配和调节能力较弱;高外显攻击者较之低外显攻击者的P300波幅更小表明其存在注意等方面的认知加工缺陷,N400波幅更小表明其对愤怒面孔进行语义编码时加工更为流畅;外显攻击组与内隐攻击组在FCz和Cz电极点上不同。这为内隐/外显攻击二者有着独立结构提供了行为与认知神经科学的证据。     

代词歧义消解中隐含意义的理解

通过两个眼动实验考察了在代词歧义消解中人们如何根据语境并利用语用知识理解隐含意义.实验一以24个语篇为实验材料,采用单因素两水平重复测量设计.结果表明间接方式下关键句阅读时间较长.实验二采用同样的实验设计,结果表明脱离语篇语境的关键句在不同条件下阅读时间相当.实验结果支持隐含意义的理解在句子加工的早期就已开始的联结主义观点.     

外显和内隐情绪韵律加工的脑机制：近红外成像研究

准确识别言语中的情绪韵律信息对社会交往非常重要。本研究采用功能近红外成像技术, 探索外显和内隐情绪加工条件下愤怒、恐惧、快乐三种情绪韵律加工过程中的大脑皮层神经活动。结果表明, 对愤怒、恐惧、快乐韵律进行特异性加工的脑区分别为左侧额极/眶额叶、右侧缘上回、左侧额下回, 其中右侧缘上回脑区同时受到情绪和任务的调控。此外, 右侧颞中回、颞下回和颞极在情绪外显任务中的激活明显强于内隐任务。本研究的结果部分支持了情绪韵律的层次模型, 也对该模型的第三层次, 即“额区对语音情绪信息的精细加工需要外显性情绪加工任务参与”提出了质疑。     

阅读中文时信息整合的即时性

通过两个实验对中文语篇理解中相关背景信息的激活与整合到底是即时发生抑或延时进行这一问题进行了探讨。研究所用的阅读材料都包含一个目标句,它与局部语境一致,但与前文提供的背景信息冲突或无关。实验一采用自定步速逐行阅读技术,考察了一致性条件以及句子结束的标记（即句号）是否存在对目标句阅读时间的影响。结果发现,句子结束的标记是否存在并不影响目标句整合加工的进行。实验二运用眼动追踪技术着重探讨信息整合加工能否在目标句关键区中即时进行,实验条件仍为当前信息与背景信息的一致性,重点考察其对目标句中关键前区、关键区及关键后区的作用。结果表明,自变量的操纵导致关键区中反映初次加工的指标产生可靠的效应。这一结果表明中文语篇理解中整合加工的过程开始得非常迅速,是一个即时引发、而非延时进行的过程     

内隐和外显道德评价的比较研究——来自眼动的证据

为探索内隐道德直觉和外显道德推理在道德评价中的差异及其内在机制,此研究将道德图片内容限定在伤害/关心维度,同时考虑道德效价以及情绪唤醒度,利用眼动追踪技术,考察内隐和外显道德任务中,道德直觉和道德推理的眼动轨迹及其加工过程差异。眼动结果发现,外显和内隐任务中个体均对低唤醒道德图片的首次注视时间更短,对低唤醒不道德图片总注视时间更长; 内隐任务和外显任务早期自动化加工阶段的平均凝视时间无显著差异; 内隐任务中,对不道德图片比对道德图片晚期平均凝视时间更长,瞳孔直径在中晚期时显著增加。此研究结果提示无论是道德直觉过程还是道德推理过程都是意识和无意识之间的相互作用,但是道德直觉过程的加工可能存在时间上的滞后性。     

Developmental changes in units of processing in reading

A visual search task was used to investigate the development of word processing skills used in reading meaningful prose. Children from the second and fourth grades and college students were asked to locate a prespecified letter, syllable, word, or category exemplar as they read through sentences. Target detection time, sentence reading time, and sentence comprehension were measured. The results provide converging evidence that whole words were the preferred units of processing during reading for all three grade levels. Reading rates for sentences in the word search condition were comparable to normal reading rates. The search for smaller units required additional processing time, but word and category search times differed only for the youngest subjects.     

Sentence processing strategies in Spanish and English

In parallel experiments, 12 English- and 12 Spanish-speaking subjects read right-branching and self-embedded sentences with one, two, or three subordinate clauses, in their native languages. Subjects read the sentences one word at a time, the subjects controlling the rate of presentation by means of a computer keyboard. The reading time for each word was recorded. After each sentence subjects performed one of four comprehension tasks. Reading times indicated that Spanish- and English-speaking subjects employ different processing strategies. Results of the comprehension tasks indicated that Spanish-but not English-speaking subjects understood self-embedded sentences with two subordinate clauses. These results are discussed in terms of the relative importance of the clause as a perceptual unit in the two languages, and the implications of the differences in comprehension for theories of sentence processing.     

初中二年级学生字词阅读知觉广度的眼动研究

采用眼动研究中经典的移动窗口技术范式探讨中学生字词阅读知觉广度。通过两个实验分别对17名初中二学生和12名初中二学生进行了汉语字、词阅读知觉广度的眼动研究。实验1结果表明,初中二年级学生字窗口条件下的阅读知觉广度为注视点左侧1个单字到右侧2个单字的范围;实验2结果表明,双字词窗口条件下的阅读知觉广度为注视点左侧1个双字词到右侧1个双字词的范围。本研究推论汉语阅读过程进行的是词单元加工,而不是单字。     

Lexical processing during saccades in text comprehension

We asked whether people process words during saccades when reading sentences. Irwin (1998) demonstrated that such processing occurs when words are presented in isolation. In our experiment, participants read part of a sentence ending in a high- or low-frequency target word and then made a long (40°) or short (10°) saccade to the rest of the sentence. We found a frequency effect on the target word and the first word after the saccade, but the effect was greater for short than for long saccades. Readers therefore performed more lexical processing during long saccades than during short ones. Hence, lexical processing takes place during saccades in text comprehension.     

The processing of constituent characters in Kanji words in proofreading Japanese sentences

In two proofreading experiments the processing of constituent characters in Japanese words was studied. In Experiment 1, the subjects were asked to detect misspellings on a CRT displaying a character, a word, a phrase, or a full sentence at a time. In Experiment 2, a comprehension task was added to make sure that the subjects read sentences in left-to right fashion with comprehension. Both experiments showed consistent results. The manipulation of visual similarity between misspelled and correct characters revealed that misspellings having supraletter features nearly identical to the correct characters received lower detection rates, and that the subjects utilized word-level information when proofreading. The disruptive effect on character processing in reading a sentence that was expected from the unitization hypothesis (Healy & Drewnowski, 1983) was not found. The constituent-level units in Japanese words are considered to be functionally equivalent to word-level units, instead of constituting a hierarchy.Part of this research was presented at the Second International Conference on Visual Search, Durham, U.K., September 1990

Interruption-similarity effects during discourse processing

We examined the effect of interruption on reading to determine if discourse processing is susceptible to similarity-based interference. Participants read pairs of passages, either one before the other (in the continuous condition) or with the sentences of the two passages interleaved (in the interruption condition). In addition, the similarity of the types of passages (narrative or expository) in a pair was manipulated. Performance was measured with self-paced reading time of the sentences and with accuracy in answering comprehension questions. In two experiments, interruption slowed the reading of text sentences; this effect of interruption was greatest when the interrupting text was of the same style as the primary text (an interruption-similarity effect). We discuss these results with respect to current models of the role of working memory in discourse processing.

Phonemic effects in reading comprehension and text memory

Two experiments investigated the role of phonemic information in adult reading comprehension and replicated the visual tongue-twister effect in a new paradigm–a modified probe memory task. College students took longer to read sentences that repeated word initial consonants (tongue-twisters) than matched control sentences. Equally important, subjects also took longer to respond to probe words from tongue-twisters. Slower response times in both the sentence reading task and the probe memory task indicate that the tongue-twister effect is indeed phonemic in nature and that phonemic information is used in memory during comprehension.
