认知风格的研究进展

在心理学研究领域,风格是对个体差异进行的描述,指个体在认知、个性等方面一贯的外在表现方式。学界关于风格的研究最早可追溯至古希腊的气质学说。现代心理学意义上的风格研究,则与Oalton、James、Jung、Bartlett等人的工作密不可分。Allport于1937年提出的生活风格(1ifestyles),第一次深思熟虑地将认知同风格从理论上联系起来。从20世纪40年代开始至今,人们围绕着认知风格开展了大量研究,获取了丰富的经验。一般认为。认知风格指个体信息加工过程中表现出的个性化的和一贯性的偏好方式。     

认知加工中时间与非时间信息的相互关系

在认知心理学领域,关于时间信息和非时间信息在认知加工中关系的争论有：相互独立、相互竞争、相互促进三大观点。本文对支持这三种观点的实验分别进行了分析、整理,并在此基础上概括出特定条件下时间信息与非时间信息的相互关系：事件结构一致条件下,两类信息在认知加工中表现为相互促进;如果事件结构不一致,而心理负荷(即两类信息所需注意资源之和)超过了注意总资源,两类信息表现为相互竞争;若心理负荷没有超过注意总资源,两类信息则表现为相互独立。     

抑制机制发展研究述评

近年来,抑制机制的发展问题已成为认知心理学界研究的热点问题之一。本文主要从儿童早期抑制发展和抑制机制老化两方面介绍了抑制机制发展研究的新进展,并阐述了目前抑制研究领域中存在的问题和不足之处。     

抑郁认知易感性的新解释——双重加工模型

双重加工模型认为人类拥有两种信息加工模式,联想模式是快速、不需努力的加工,以良好学习联想(Well-learned associations)为基础:反思模式是慢速的、需要付出努力的加工,建立在基于规则的符号推理基础上,联想模式的发生是自动化的,当预期被违反时,执行反思模式,并需要足够的认知资源.当反思加工没有校正消极的有偏向的联想加工时,就会表现出抑郁的认知易感性.双重加工模型对抑郁认知易感性的评估、病原学和治疗提出了新的看法.     

引入眼动注视点的联合-交叉负载多模态认知诊断建模

多模态数据为实现对认知结构的精准诊断及其他认知特征(如, 认知风格)的全面反馈提供了可能性。为实现对题目作答精度、作答时间(RT)和视觉注视点数(FC)的联合分析, 本文基于联合-交叉负载建模法提出3个多模态认知诊断模型。实证研究及模拟研究结果表明: (1)联合分析比分离分析更适用于多模态数据; (2)新模型可直接利用RT和FC中信息提高潜在能力或潜在属性的估计准确性; (3)新模型的参数估计返真性较好; (4)忽略交叉负载所导致的负面结果比冗余考虑交叉负载所导致的更严重。

行为决策中诱饵效应的认知加工机制

在原选项集中加入一个诱饵选项能够使人们的选择发生改变, 这就是诱饵效应。研究者发现可以通过设置相似诱饵、妥协诱饵、吸引诱饵以及幽灵诱饵等达到诱导决策者选择目标选项的目的。当前, 很多研究探索了诱饵效应的认知加工机制, 有研究者基于启发式加工和分析式加工的视角开展研究, 也有研究者从维度加工和选项加工的视角对此进行探索。诱饵效应的认知加工过程受到年龄、后悔情绪、决策形式以及时间压力等因素的影响。未来的研究需要构建适用于各类诱饵效应的统一的认知加工机制模型, 探索知觉在诱饵效应形成过程中的基础性作用, 探索个体的决策风格对不同类型诱饵效应的影响, 并通过合理利用诱饵效应助推社会发展。     

情绪影响认知加工策略内隐机制的实验研究

大量研究表明情绪可以影响加工策略：积极情绪与简单的启发式加工相联系,而消极情绪与系统的精细加工相联系。本研究运用信号检测论的方法,将被试的判定标准与加工能力分离开来,结果发现,虽然对两组被试（积极情绪组、消极情绪组）的回忆任务均提出相同的明确要求,但积极情绪组仍然运用了较为宽松的判定标准,反映了情绪对认知加工策略的无意识影响。另外,d＇值在两组间没有差异表明积极情绪组并不缺少加工能力。在此基础上,认为应该放弃从能力的角度看待情绪与加工方式之间的关系,注重研究情绪与具体加工特点之间的关系。     

自尊的认知加工偏向研究述评

随着认识心理学的发展,人们从认知的角度对自尊进行了拓展性的研究。主要揭示不同自尊水平对认知加工偏向的影响,找出低自尊水平的认知加工特点并期望通过选择性训练来提升个体的自尊水平。关于自尊的认知加工偏向的心理机制主要是心境一致性效应和特质一致性效应。虽然这一取向的研究具有巨大的实践意义,但是还没有取得阶段性成果。     

Utilization of Prosodic Information in Syntactic Ambiguity Resolution

Two self paced listening experiments examined the role of prosodic phrasing in syntactic ambiguity resolution. In Experiment 1, the stimuli consisted of early closure sentences (e.g., “While the parents watched, the child sang a song.”) containing transitive-biased subordinate verbs paired with plausible direct objects or intransitive-biased subordinate verbs paired with implausible direct objects. Experiment 2 also contained early closure sentences with transitively and intransitive-biased subordinate verbs, but the subordinate verbs were always followed by plausible direct objects. In both experiments, there were two prosodic conditions. In the subject-biased prosodic condition, an intonational phrase boundary marked the clausal boundary following the subordinate verb. In the object-biased prosodic condition, the clause boundary was unmarked. The results indicate that lexical and prosodic cues interact at the subordinate verb and plausibility further affects processing at the ambiguous noun. Results are discussed with respect to models of the role of prosody in sentence comprehension.     

In Defense of Competition During Syntactic Ambiguity Resolution

In a recent series of publications (Traxler et al. J Mem Lang 39:558–92, 1998; Van Gompel et al. J Mem Lang 52:284–07, 2005; see also Van Gompel et al. (In: Kennedy, et al.(eds) Reading as a perceptual process, Oxford, Elsevier pp 621–48, 2000); Van Gompel et al. J Mem Lang 45:225–58, 2001) eye tracking data are reported showing that globally ambiguous (GA) sentences are read faster than locally ambiguous (LA) counterparts. They argue that these data rule out ‘constraint-based’models where syntactic and conceptual processors operate concurrently and syntactic ambiguity resolution is accomplished by competition. Such models predict the opposite pattern of reading times. However, this argument against competition is valid only in conjunction with two standard assumptions in current constraint-based models of sentence comprehension: (1) that syntactic competitions (e.g., Which is the best attachment site of the incoming constituent?) are pooled together with conceptual competitions (e.g., Which attachment site entails the most plausible meaning?), and (2) that the duration of a competition is a function of the overall (pooled) quality score obtained by each competitor. We argue that it is not necessary to abandon competition as a successful basis for explaining parsing phenomena and that the above-mentioned reading time data can be accounted for by a parallel-interactive model with conceptual and syntactic processors that do not pool their quality scores together. Within the individual linguistic modules, decision-making can very well be competition-based.     

Lexical and Prosodic Effects on Syntactic Ambiguity Resolution in Aphasia

The purpose of this study was to determine whether and when individuals with aphasia and healthy controls use lexical and prosodic information during on-line sentence comprehension. Individuals with aphasia and controls (n = 12 per group) participated in a self-paced listening experiment. The stimuli were early closure sentences, such as "While the parents watched(,) the child sang a song." Both lexical and prosodic cues were manipulated. The cues were biased toward the subject- or object- of the ambiguous noun phrase (the child). Thus, there were two congruous conditions (in which both lexical cues and prosodic cues were consistent) and two incongruous conditions (in which lexical and prosodic cues conflicted). The results showed that the people with aphasia had longer listening times for the ambiguous noun phrase (the child) when the cues were conflicting, rather than consistent. The controls showed effects earlier in the sentence, at the subordinate verb (watched or danced). Both groups showed evidence of reanalysis at the main verb (sang). These effects demonstrate that the aphasic group was sensitive to the lexical and prosodic cues, but used them on a delayed time course relative to the control group.     

句法歧义消解与句子理解研究综述

０引言 句法分析是句子理解的一个基本过程,它操作的速度非常快,操作的结果只能瞬间保留,因此,直接观察有一定困难。然而,研究者可以通过探讨句法歧义消解机制间接研究句法分析过程［１］。近年来,句法歧义消解已经逐渐成为探讨句子加工的一个非常活跃的研究领域［２－９］。本文首先对当前几种典型的有关句法歧义消解与句子加工的理论进行评述,然后简要回顾一下有关的实验证据。１句法歧义消解的理论 在过去的二十年里,句子理解研究主要集中在两个基本的实验发现上,第一,即使句子的结构暂时有歧义,人们也能立即作出一个特定的分…     

The Effect of Phonemic Repetition on Syntactic Ambiguity Resolution: Implications for Models of Working Memory

Two reading experiments investigated the extent to which the presence of phonemic repetition in sentences influenced processing difficulty during syntactic ambiguity resolution. In both experiments, participants read sentences silently as reading time was measured. Reading time on sentences containing a temporary syntactic ambiguity was compared to reading time on unambiguous control sentences. Sentences either did or did not contain repeated phonemes. The results showed that reading time was longer for sentences containing a syntactic ambiguity than for unambiguous control sentences. Reading time was also longer on sentences containing repeated phonemes than on sentences that did not contain repeated phonemes. Phonemic repetition did not increase the time taken for syntactic ambiguity resolution; rather, the effects of syntactic ambiguity and phonemic repetition were temporally distinct, with the effect of phonemic repetition following the effect of syntactic ambiguity. Implications for theories of working memory are discussed.

The Resolution of the Dative NP Ambiguity in Korean

An eye-movement study examined the ambiguity of the dative noun phrase (NP) in Korean, which may be attached either to the main verb or to a relative verb. Experimental sentences of the form NP-Nom NP-Dat NP-Nom V (dative) NP-Acc V (dative or simple transitive; Nom = nominative; Dat = dative; V = verb; Acc = accusative) were tested. Garden-path theory predicts that comprehension difficulty occurs when the main verb is transitive, forcing the dative NP to be attached to the relative verb, because the dative NP will have already been attached in the clause posited when the first nominative NP is read. In contrast, lexically based theory predicts that comprehension difficulty occurs when the main verb is a dative verb, because the dative NP will be attached to the first verb encountered (the relative verb). The present study did not fully support either theory, because the differences seen in the experimental conditions appeared, at least in part, in the control conditions. However, the results were much different from the prediction of lexically based theory. Reading was faster, and regressive eye movements fewer, in the dative-ambiguous condition than in the transitive-ambiguous condition. Some reasons for the unexpected difficulty of the transitive-unambiguous condition are advanced.
