因果错觉的实验研究

本研究分别从可控情境和不可控情境两方面探讨了在工具性条件反射中,人对因果关系的认知的特点。结果发现：1．在可控情境下。延迟反馈可能导致被试的因果错觉;2、在不可控情境下,被试同样表现出因果错觉：迷信和控制幻觉,并且这种现象具有一定的普遍性;3、提供恰当的外部线索能有效地帮助被试消除已经形成的因果错觉。     

Considerations for the Use of Sentence Completion Tests

Often, sentence completion tests are administered to clients without a clear sense of the clinical questions to be investigated, and, therefore, the appropriate sentence completion instrument to be used. The multitude of forms that have evolved in the last fifty years have made it difficult for clinicians to make informed decisions about which form to use and for what purpose. This article presents ten general guidelines or considerations for the effective use of this popular but sometimes misused psychological assessment method. Practitioners are urged to consider such issues as oral versus written presentation of items, item content in terms of positive or negative stimulus pull, the structure of sentence stems, the original purpose of a given test in regard to intended population and theoretical orientation of the author, and the empirical validity of tests.     

Executive function and intelligence in the resolution of temporary syntactic ambiguity: an individual differences investigation

In the current study, we examined the role of intelligence and executive functions in the resolution of temporary syntactic ambiguity using an individual differences approach. Data were collected from 174 adolescents and adults who completed a battery of cognitive tests as well as a sentence comprehension task. The critical items for the comprehension task consisted of object/subject garden paths (e.g., While Anna dressed the baby that was small and cute played in the crib), and participants answered a comprehension question (e.g., Did Anna dress the baby?) following each one. Previous studies have shown that garden-path misinterpretations tend to persist into final interpretations. Results showed that both intelligence and processing speed interacted with ambiguity. Individuals with higher intelligence and faster processing were more likely to answer the comprehension questions correctly and, specifically, following ambiguous as opposed to unambiguous sentences. Inhibition produced a marginal effect, but the variance in inhibition was largely shared with intelligence. Conclusions focus on the role of individual differences in cognitive ability and their impact on syntactic ambiguity resolution.     

说明文阅读中因果序列的表征

结合自定步调阅读与句子启动再认范式, 探讨说明文阅读过程中因果序列的表征问题。研究包括3个实验, 实验1的文本提供一个包括4个概念的因果链(如, A－B－C－D), 文本最后设置包含概念A或概念B或概念C的句子, 对概念D进行探测, 结果发现, 对于概念D的再认启动作用, 概念C＞概念B＞概念A; 实验2改变因果链的说明顺序, 使之与因果链本身次序不一致, 结果与实验1一致; 实验3的文本分别介绍两条独立的因果链(如A－B－C; D－E－F), 最后呈现包含概念A或概念D的句子, 对概念C进行探测, 结果发现, 包含概念A的句子理解启动了相关因果链, 使读者对随后呈现的概念C的再认反应加快。基于本研究结果, 结合相关研究, 本文尝试提出说明文文本表征的建构模式。     

句子语境中汉语词汇形、音作用的眼动研究

采用眼动方法, 通过两个实验考查了句子语境中汉语词汇形、音的作用及其作用的时间进程。结果发现：(1)在高限制性句子语境中, 音同的凝视时间和总注视时间显著短于无关控制; (2)在低限制性句子语境中, 音同、形似的首视时间均显著短于无关控制; (3)词频效应出现在低限制性句子语境中。该结果表明, 句子语境影响词汇形、音的作用及作用的时间进程, 汉语词汇的意义可以由字形直接通达, 也可以由形和音两条路径得到通达。     

How do 8‐month‐old infants recognize causality in object motion and that in human action?1

Abstract: In Experiment 1, 8‐month‐old infants were first habituated to the event in which a moving object collided with another behind an occluder, then they were shown the two test events with no occluder: the contact event, in which the two objects actually collided, and the non‐contact event, in which the second object started to move without contact with the first. The infants looked at both events for an equal amount of time. In Experiment 2, in which the first object was a human actor, however, infants looked at the non‐contact event reliably longer than the contact event. In Experiment 3, in which both objects were human actors stood face‐to‐back, infants looked at the non‐contact event longer, whereas in Experiment 4, in which human actors faced toward each other, infants looked at both events equally. In Experiment 5, in which the first actor told the second to go, 10‐month‐old infants looked at both events for an equal amount of time. These results suggest that 8‐ and 10‐month‐old infants appreciate different causal principles between objects and humans, and that, in doing this, they may acknowledge the possibility of communication between humans.     

Multiple causal pathways in attention-deficit/hyperactivity disorder – Do emerging executive and motivational deviations precede symptom development?

The multiple causal pathways model on the etiology of attention-deficit/hyperactivity disorder (ADHD) is well established. However, developmental implications of the model are not yet sufficiently analyzed. The model implies that critical neural and neuropsychological deviations from normative development precede secondarily developing ADHD symptoms. Cognitive, “cool” inhibitory control (CIC) and reward-related, “hot” functions (RRF) are regarded as neuropsychological basic deficits that indicate independent causal pathways. Both functions involve top-down control networks that undergo major normative developmental changes in the preschool period. We formalized the following assumptions in a path model: (a) CIC and RRF predict change in ADHD symptoms in the preschool period, (b) the reverse is not true, and (c) CIC and RRF independently contribute to this prediction. A community-based sample of 125 (71 boys) preschoolers was assessed at at age 4 and 5 years. At each assessment wave, CIC and RRF were measured by a battery of age-appropriate valid tasks. ADHD symptoms were measured by a clinical parent interview. Evaluation of model fit using manifest maximum likelihood parameter estimation clearly supported the hypothesized path model while controlling for gender of child and maternal education level. Thus, regarding the basic deficits of CIC and RRF, the results add evidence on the developmental implications of the multiple causal pathways model. Our findings point to the potential significance of these early emerging characteristics as indicators of risk and as targets for preventive interventions.     

儿童在因果知识领域内的选择性学习

儿童的选择性学习是目前认知发展领域的热点问题。儿童在因果知识领域内的选择性学习(即选择性因果学习)对于回答儿童如何获取知识这个经典问题具有重要意义。儿童的选择性因果学习表现在对他人解释的辨别、评估与采纳上。他们会主动向可靠的信息提供者寻求解释, 并在接收回答后表现出选择性跟进反应。对于他人的回答, 年幼儿童不仅能根据言语线索辨别出解释性陈述, 还能依据解释的结构特征选择更好的陈述加以采纳, 年长儿童甚至可以从不同模式的解释中灵活地学习更适宜的因果知识。未来研究应深入关注解释的其它特征在儿童选择性因果学习中的作用, 进一步探讨选择性因果学习的认知机制。     

主人公的动机水平对句子理解中心理模拟的影响

通过两个实验, 考察了主人公的动机水平对句子理解中读者的心理模拟的影响。实验1采用移动窗口技术, 记录读者阅读句子中目的地词语的时间; 实验2采用视觉情景眼动范式, 主试播放描述运动的句子, 同时呈现相应的情境图片, 记录读者扫描图片中主人公、路径和目的地的时间。实验结果表明：(1)主人公的动机水平影响读者对目的地词语的阅读时间, 主人公的动机水平越高, 读者的阅读时间就越短; (2)读者对情景图片的扫描受主人公的动机水平影响, 主人公的动机水平越高, 读者对路径区域的扫描时间就越短, 对目的地区域的扫描时间就越长。两个实验均表明, 在句子的实时加工中, 读者可以通过再入情境, 遵循先内后外的顺序, 先模拟主人公的动机水平, 继而模拟主人公的动作, 从而影响对句子的注视和理解。研究结果支持语言加工的具身认知观。     

简单算术对汉语特定句型的结构启动

结构启动是指个体在产生或理解一个结构时,倾向于重复使用或仿照刚刚加工过的结构。与句法启动不同的是,结构启动除了以句子,也可以以其它抽象结构作为启动项。Scheepers et al. (2011) 首次以具有结构偏向性的抽象算式作为启动项,证实了高附着和低附着的简单算式对英语母语者产出高附着和低附着关系从句具有结构启动效应。在此基础上,本研究引用数学算式作为启动项,以汉语特定句型结构NP1+有+NP2+恨+(AP)为切入点,分别选取汉语成人和儿童受试,检验简单算式对汉语母语者产出或理解特定句型的结构启动效应。本研究发现：1）算式结构对汉语特定句型的产出具有结构启动效应。2）算式结构对汉语歧义句的解读具有结构启动效应。3）儿童和成人在产出和理解的启动实验中具有不同结构启动效应,且儿童的结构启动效应比成人的结构启动效应更强。4）算式结构和语言句式在认知上具有共享的结构表征。
