Word Learning and Attention Allocation Based on Word Class and Category Knowledge

Attention allocation in word learning may vary developmentally based on the novelty of the object. It has been suggested that children differentially learn verbs based on the novelty of the agent, but adults do not because they automatically infer the object's category and thus treat it like a familiar object. The current research examined whether adults and children differentially learn words or attend to objects without access to category knowledge in a relatively difficult (Experiment 1, adult n = 54, child n = 66) and a relatively easy task (Experiment 2, adult n = 88, child n = 62). Results show that category knowledge affects noun and verb extension for children but not adults and that adults similarly attended to objects when learning a verb regardless of category knowledge. These findings highlight the importance of investigating how word class, attention allocation, and categorical inference interact across development. Copyright © 2014 John Wiley & Sons, Ltd.     

汉语个体量词认知研究述评

个体量词是汉藏语系的特色词类, 它一般不能单独充当句子成分, 只有与名词组合在一起构成计数名词短语以后, 才能够灵活地使用。个体量词的存在顺应了汉语语音、语法的发展要求, 体现了汉民族具象思维发达的思维特点。它按照一定的规律有选择地搭配名词, 并且在认知加工中对名词发挥着重要的选择与限制作用。研究个体量词的存在价值、个体量词在认知加工中的作用、个体量词与名词之间相互关联的实质, 对个体量词的理解和学习具有重要的意义。     

Language, thought, and real nouns

We test the claim that acquiring a mass-count language, like English, causes speakers to think differently about entities in the world, relative to speakers of classifier languages like Japanese. We use three tasks to assess this claim: object-substance rating, quantity judgment, and word extension. Using the first two tasks, we present evidence that learning mass-count syntax has little effect on the interpretation of familiar nouns between Japanese and English, and that speakers of these languages do not divide up referents differently along an individuation continuum, as claimed in some previous reports [Gentner, D., & Boroditsky, L. (2001). Individuation, relativity, and early word learning. In M. Bowerman, & S. Levinson (Eds.), Language acquisition and conceptual development (pp. 215-256). Cambridge University Press]. Instead, we argue that previous cross-linguistic differences [Imai, M., & Gentner, D. (1997). A cross-linguistic study of early word meaning: Universal ontology and linguistic influence. Cognition, 62, 169-200] are attributable to “lexical statistics” [Gleitman, L., & Papafragou, A. (2005). Language and thought. In K. Holyoak, & R. Morrison (Eds.), Cambridge handbook of thinking and reasoning (pp. 633-661). Cambridge University Press]. Speakers of English are more likely to think that a novel ambiguous expression like “the blicket” refers to a kind of object (relative to speakers of Japanese) because speakers of English are likely to assume that “blicket” is a count noun rather than a mass noun, based on the relative frequency of each kind of word in English. This is confirmed by testing Mandarin-English bilinguals with a word extension task. We find that bilinguals tested in English with mass-count ambiguous syntax extend novel words like English monolinguals (and assume that a word like “blicket” refers to a kind of object). In contrast, bilinguals tested in Mandarin are significantly more likely to extend novel words by material. Thus, online lexical statistics, rather than non-linguistic thought, mediate cross-linguistic differences in word extension. We suggest that speakers of Mandarin, English, and Japanese draw on a universal set of lexical meanings, and that mass-count syntax allows speakers of English to select among these meanings.     

义符在中文名词和动词分类中的作用

通过3个实验,考察了义符在中文名词和动词分类中的作用。实验1表明,义符提供了重要的语法种类信息,在中文名词和动词分类中有重要作用。当义符与词类一致时分类快,与词类相反时对分类起干扰作用。实验2表明,高频词分类时间短,错误率亦低。义符和词频有显著的交互作用,义符对低频词分类作用更大。实验3表明,具体性高的词分类时间短,错误率亦低。义符和具体性之间无显著的交互作用。整个研究表明,义符不仅是结构的“块”,也是语义的“块”,还是语法的“块”。所以如此,与中文名词和动词的结构特点有关。中文名词大多用义符标记事物的物质组成,动词大多用义符标记动作发出的器官或完成动作的工具。义符的语法意义的发现丰富了中文和中文认知的理论,对中文教学也有重要启示     

影响汉语动词、名词识别因素的回归分析

采用回归分析的方法,考察了6个因素对汉语动词、名词识别的影响。结果表明,各变量间有一定的相关,也有相对的独立性。词频、获得年龄和义符熟悉性对词汇识别有显著影响。情境获得性与具体性相关显著,当回归模型中包含情境获得性时,具体性的作用减弱。获得年龄与义符熟悉性在名词回归方程中的解释量大于在动词中的。汉语动词和名词的回归模式既与拼音文字有明显差异,也有一定的共性。这是由汉字的特殊性和语言的共性共同决定的。     

Speech vs. reading comprehension: an explorative study of gender representations in Norwegian

As research on the construction of a mental representation of referent gender in speech comprehension is scarce, this study examined whether factors identified in reading comprehension exert similar influence in speech comprehension. Conceptually replicating previous research, a sentence continuation evaluation task was set up in two modalities, as a listening task and as a time-confined reading task (i.e. to correspond to the time constraint when listening). In line with previous findings from self-paced reading paradigms we found gender representations in language comprehension to be grounded in the interaction between textual (grammatical) and background (stereotypical) information. Extending previous research, the effect of stereotypical information was however modulated by presentation modality. In all, although speech and reading comprehension share higher-level processes of comprehension, this study provides first evidence that differences in comprehension might occur due to differences such as orthographic access or attention allocation.     

Why is a verb like an inanimate object? Grammatical category and semantic category deficits

Semantic category effects, such as difficulties in naming animate things relative to inanimate objects, have been explained in terms of the relative weightings of perceptual and functional features within the semantic representations of these concepts. We argue that grammatical category deficits, such as difficulties in naming nouns relative to verbs, can be explained within the same framework. We hypothesize that verb concepts are richer in functional than sensory features and present a model of the semantic representations of animate nouns, inanimate nouns, and verbs. The model demonstrates that sensory feature damage results in a deficit for naming living things but spares verb naming, and functional feature damage results in a deficit for naming inanimate objects and verbs. We then report the assessment results of two patient groups. In accordance with the model's predictions, the "verb spared" patients were consistently worse at naming living things than inanimate objects, and their definitions of both living and nonliving items were lacking in sensory information. We conclude that damage to sensory features in semantic representations causes difficulties in naming concrete nouns relative to action verbs, and within the grammatical category of nouns, animate items will be more severely affected. Imageability was shown to be a strong predictor of naming performance in the "verb deficit" patients, and when this variable was controlled no class effect remained. Production of definitions revealed no differential damage to sensory or functional features, and no consistent effect of animacy in naming was shown. While the model suggests that verb deficits might occur in patients for whom functional features are damaged relative to sensory features, we conclude that the "verb deficit" shown in our patients (and potentially in many previously reported cases) was an artifact of the lower imageability of verbs in confrontation naming tasks.     

Cognitive, Linguistic, and Social Aspects of Adults' Noun Definitions

Low-income, rural adults and middle-income, urban adults provided oral definitions for eight common nouns. Two general issues were addressed: (1) whether the rural adults' definitions would conform to the well-documented Aristotelian form typically found among middle-class, well-educated adults; and (2) whether different definitional types would emerge for two different noun classes, social vs. object nouns. Participants' definitions were examined for conceptual content and linguistic form. Among rural participants, the mean proportion of definitions conforming to the Aristotelian model was .13, contrasted with .69 for the urban participants. Also, rural adults were significantly less likely to cast definitions in the conventional linguistic form than were urban adults. On other measures of definitional skill as well, rural participants demonstrated less mastery. There were no significant differences in definitional form between social and object nouns. Various explanations for the findings are considered.     

Mass Nouns in a Logic of Classes as Many

A semantic analysis of mass nouns is given in terms of a logic of classes as many. In previous work it was shown that plural reference and predication for count nouns can be interpreted within this logic of classes as many in terms of the subclasses of the classes that are the extensions of those count nouns. A brief review of that account of plurals is given here and it is then shown how the same kind of interpretation can also be given for mass nouns.     

不同提取条件下中性抽象名词的自我选择权效应

采用中性抽象名词探测在再认测试和自由回忆条件下的自我选择权效应。实验一采用选择与迫选的方式考察抽象名词在再认条件下的自我选择权效应;实验二进一步验证被试在我选择和他选择条件下对抽象名词的自由回忆的差异。结果表明:无论在再认测试还是自由回忆测试,被试对自我选择的抽象名词的记忆数量都显著高于迫选和他人选择条件下的抽象名词记忆的数量,中性抽象名词表现出了自我选择权效应,拓展了前人使用假词时在自由回忆条件下未表现出自我选择权效应。因此,自我选择权效应在自由回忆条件下可以存在于抽象名词的水平上。
