表象对成语记忆影响的实验研究

通过混合实验设计探讨表象对成语记忆的影响.实验结果表明,据成语形成图厕形式的表象能提高图画命名中外显记忆的成绩,显著提高内隐记忆的成绩,尤其是低透明度成语的内隐记忆成绩;但在成语补全中,对两种记忆均没有显著影响.可见.表象同时具有概念加工和知觉加工的性质,表象作用对所形成的表象的形式与测试任务的一致性程度敏感.     

小学生数学问题解决与心理表征

本研究的目的是揭示数学能力和心理表征之间的关系。我们的假设是数学成绩好的儿童心理表征能力也强。参加实验的被试是64名在校的小学5年级学生,他们的年龄是11─12岁,男女各半。数学测验包括两部分,一部分是需要直接空间表象操作的题目,另一部分是需要逻辑推理和图式知识进行计算的应用题。心理表征能力用的是两项空间表象操作测验:Form Board Test(FT)和Surface Development Test(ST).结果表明儿童的数学测验成绩和空间表征能力呈正相关,数学测验成绩得分高的儿童空间表征测验的得分也高,说明小学生数学问题解决能力与空间表象操作能力有密切的关系。

表象测量方法述评

表象测量在训练领域广泛应用,也是训练成败的关键环节.表象测量方法可分为口头报告纸笔法、实验操作法,以及神经科学技术共三种方法.其中纸笔报告法以量表测量为主,包括Betts量表、视觉表象清晰度量表及其修订版和运动表象清晰度量表及其修订版;实验操作法以心理旋转为基本范式;神经科学技术主要以经颅磁刺激和功能磁共振成像为主,测量多种表象过程中不同脑区兴奋性.三者各有优劣,均有待提高和改进.     

数字表征的表象赋义效应:来自数字线估计任务的证据

已有研究中数字线估计任务几乎都使用纯数字。本研究以二到六年级儿童为被试,采用纯数字任务和赋义数字任务来探索赋义表象对数字表征形式的影响。结果表明,对0~1000的数字赋义后,对数模型的解释力上升,而线性模型的解释力下降;表象大小对于赋义数字的估计影响显著,大表象赋义提高了对数模型解释力而降低了数字估计的准确性,小表象的影响比较微弱。     

汉语惯用语的产生机制

惯用语是固定表达的一种。非构造观点认为, 惯用语已经词汇化, 惯用语理解是提取过程; 构造观点认为, 惯用语意义是建构的, 成分的字面意义对惯用语理解起重要作用。混合模型认为, 惯用语既有整体表征, 又有成分单词表征, 二者都可以成为表征和通达的单元。通过三个实验, 考察了汉语惯用语的产生机制。实验1考察在惯用语产生中是否存在整体表征和成分表征; 实验2考察在惯用语产生中是否存在从成分单词或成分词素表征到整体表征的激活; 实验3考察在惯用语产生中是否存在从整体表征到成分单词或成分词素的激活。结果表明: (1) 汉语惯用语属于混合表征, 既有整体表征, 又有成分单词、成分词素表征; (2)成分词素表征是惯用语整体表征和成分单词表征联结的桥梁; (3) 语义可分性影响惯用语表征。     

Effects of changes in narrative time on eye movements and recognition responses

Abstract

Gibbs and O'Brien (1990) recently claimed that the images that people associate with everyday idioms reflect the deep conceptual metaphors that underlie the meanings of those idioms. However, because idiomatic strings can convey both a literal and an idiomatic meaning, people must be able to inhibit or ignore literal meanings if they are to produce mental images that uniquely reflect idiomatic meanings. We investigated the potential interference between literal and idiomatic meanings in three experiments. Experiment 1 used a mental-image production task similar to that used by Gibbs and O'Brien. Counter to Gibbs and O'Brien's claim, the images that we obtained referred overwhelmingly to the literal meanings of idiomatic strings rather than to their idiomatic meanings. Experiments 2 and 3 employed a paraphrase verification task to examine the effects of mental imagery on idiom comprehension. If the images associated with an idiom reflect that idiom's meaning, then imagery should facilitate comprehension. No evidence for facilitation was found in either experiment. Instead, imagery interfered with comprehension, as assessed by paraphrase verification time, both for idiomatic meanings and for literal, concrete meanings. We conclude that the images associated with idioms do not reflect idiom meanings.     

汉语动宾结构惯用语加工的基本单元：来自词切分的证据

采用词切分范式研究汉语动宾结构惯用语的理解机制, 探讨在惯用语理解中加工的基本单元, 揭示汉语动宾结构惯用语的表征方式。研究发现, 词切分范式对语义分解性不同的惯用语有不同的影响。在空格切分的形式下, 语素切分和非语素切分抑制了对语义高分解的动宾结构惯用语的通达, 却未影响对语义低分解的动宾结构惯用语的理解; 语素切分、非语素切分和空格切分均增加了对语义高分解的惯用语的错误率。在阴影切分的形式下, 非语素切分抑制了对语义高分解的动宾结构惯用语的加工, 同样未影响对语义低分解的惯用语的理解。整个研究表明, 在汉语动宾结构惯用语的表征中, 既存在着语素单元, 也存在着整语单元, 但整语是汉语动宾结构惯用语加工的优势单元。     

汉语习语理解研究

研究宗旨是探讨中国成人对汉语中三字习语的加工处理问题。研究材料包括：（１）动宾结构的惯用语,既有比喻意义又有字面意义;（２）动宾结构的一般三字词组;（３）偏正结构的三字惯用语,既有比喻意义又有字面意义;（４）偏正结构的一般三字词组;（５）动宾结构的惯用语。只有比喻意义而无字面意义;（６）三字词。它们都是被试所熟悉的。向３５名成人呈现这些词语和（７）无意义三字组合,要求他们作意义判别。结果表明,所有惯用语的判断反应均无显著性差异,各组惯用语的判断反应时均慢于单词,而快于一般词组。实验结果基本支持两种意义同时加工,但比喻意义优先完成的假设。此外,文章还讨论了习语的词汇化等问题。     

预测性、语义倾向性对惯用语理解的影响

通过两个移动窗口阅读实验,探讨了不同预测性和语义倾向性的惯用语在不同语境下的阅读时间。实验一发现：倾向字面意义的惯用语在比喻意义语境下有抑制效应;倾向比喻意义的惯用语在字面意义语境下有抑制效应。实验二发现：低预测性惯用语在比喻意义语境下有抑制效应;高预测性惯用语在字面意义语境下有抑制效应。研究结果否认了惯用语已词汇化的观点,支持了结构假说的观点,证明惯用语的理解是一个构造过程。     

On comprehending idioms: Do children get the picture?

This study examines children's comprehension of idioms. First, third, and fifth grade children (6, 8, and 10 years old) and college adults were read short stories containing contextual information and a key terminal sentence. The contextual information biased either an idiomatic, a literal, or am ambiguous (neutral) interpretation of the terminal sentence. The terminal sentence contained either an idiom (“fix his wagon”) or a changed form (“repair his wagon”) of the idiom. These manipulations were used to determine the role of contextual information and the conventional forms of idioms in idiom comprehension. After each story, the subjects were asked to explain the terminal sentence and to answer a “yes-no” question about the action described in the story. The results showed that idiomatic explanations and interpretations occurred more frequently for the idiom than the changed forms, and that there were strong developmental increases in making idiomatic interpretations of both forms. The results are discussed in terms of two current models of idiom comprehension.     

The multidetermined nature of idiom processing

Models of idiom comprehension differ in their predictions concerning compositionality: Some claim that idiomatic meaning is the result of compositional analysis initiated at the earliest stages of comprehension, whereas others claim that compositional analysis occurs only at late stages, subsequent to direct retrieval--especially for idioms that are highly familiar. We evaluated these alternatives in four experiments by using a variety of online and offline comprehension measures. In Experiment 1, we analyzed the normative characteristics of 219 idioms with respect to these predictions. Dimensions of interest included several measures of decomposability, familiarity, and word frequency of the idioms' verbs and nouns. In Experiments 2 through 4, we determined how these dimensions relate to several online measures of idiom comprehension. High familiarity was associated with good comprehension across all experiments; however, facilitative effects of decomposability were found only for tasks that required an overt semantic judgment. Word frequency, but not semantic decomposability of the idiom-initial verb, was associated with comprehension for some measures. These data support a model of idiom comprehension, according to which figurative meaning arises from the time-dependent availability of multiple linguistic constraints, and in which decomposability plays a limited role in the earliest stages of idiom comprehension. Normative data for 210 of the idiomatic phrases may be downloaded from the Psychonomic Society Web archive at www.psychonomic.org/archive/.     

Motor imagery vividness and symptom severity in Parkinson's disease

Motor imagery (MI), the mental simulation of movement in the absence of overt motor output, has demonstrated potential as a technique to support rehabilitation of movement in neurological conditions such as Parkinson's disease (PD). Existing evidence suggests that MI is largely preserved in PD, but previous studies have typically examined global measures of MI and have not considered the potential impact of individual differences in symptom presentation on MI. The present study investigated the influence of severity of overall motor symptoms, bradykinesia and tremor on MI vividness scores in 44 individuals with mild to moderate idiopathic PD. Linear mixed effects modelling revealed that imagery modality and the severity of left side bradykinesia significantly influenced MI vividness ratings. Consistent with previous findings, participants rated visual motor imagery (VMI) to be more vivid than kinesthetic motor imagery (KMI). Greater severity of left side bradykinesia (but not right side bradykinesia) predicted increased vividness of KMI, while tremor severity and overall motor symptom severity did not predict vividness of MI. The specificity of the effect of bradykinesia to the left side may reflect greater premorbid vividness for the dominant (right) side or increased attention to more effortful movements on the left side of the body resulting in more vivid motor imagery.     

Prospective and positive mental imagery deficits in dysphoria

We know less about positive mental imagery than we do about negative mental imagery in depression. This study examined the relationship between depressed mood and the subjective experience of emotion in imagined events; specifically, prospective imagery, and imagery in response to emotionally ambiguous stimuli. One hundred and twenty-six undergraduates completed measures of depression, imagery vividness for future events, and a homograph interpretation task in which they generated images and subsequently rated image pleasantness and vividness. As predicted, compared to low dysphoria, high dysphoria was associated with poorer ability to vividly imagine positive (but not negative) future events. These findings were augmented by the observation that high dysphorics provided lower pleasantness ratings of images generated in response to homographs they interpreted as positive. We suggest that an imbalance in the inability to vividly imagine positive but not negative future events may curtail the ability of high dysphorics to be optimistic. High dysphoric individuals are further disadvantaged: even when they interpret ambiguity positively, the resulting images they generate are associated with less positive affect. Therapeutic strategies that address both such positive-specific imagery biases hold promise for depression treatment innovation.     

Comprehension of Idioms by Children with Learning Disabilities: Metaphoric Transparency and Syntactic Frozenness

Third and fifth grade children with and without learning disabilities participated in this study. Syntactically frozen and flexible idioms and transparent and opaque idioms were used as stimuli to examine the ability to identify the correct idiom and to explain idiom meanings. Grade and diagnostic category affected performance on the explanation task but not on the forced choice task. Idiom type was also a factor affecting comprehension and explanation. Literal responses occurred rarely and were more likely to occur on the forced choice task.
