言语产生和理解中汉语个体量词的通达

个体量词是汉语的特色词类,是名词的限定词。关于个体量词的通达,目前主要有两种假说：直接选择假说和间接选择假说。实验1和实验2采用图词干扰范式考察了名词短语和简单名词产生中个体量词的通达。实验3采用启动范式考察了言语理解中个体量词的通达。结果表明,无论是在言语产生中,还是在言语理解中,都存在量词一致性效应：当启动词和目标词量词一致时反应时短,错误率亦低。整个研究表明,个体量词的通达涉及个体名词系统和个体量词系统,涉及双向选择的组合网络。个体量词的通达是直接选择和间接选择的有机结合。个体量词在名词短语产生的早期就得到了通达。     

The role of redundant verbal labels in 8- and 10-month-olds’ working memory

Verbal labels have been shown to help preverbal infants’ performance on various cognitive tasks, such as categorization. Redundant labels also aid adults’ visual working memory (WM), but it is not known if this linguistic benefit extends to preverbal infants’ WM. In two eye-tracking studies, we tested whether 8- and 10-month-old infants’ WM performance would improve with the presence of redundant labels in a Delayed Match Retrieval (DMR) paradigm that tested infants’ WM for object-location bindings. Findings demonstrated that infants at both ages were unable to remember two object-location bindings when co-presented with labels at encoding. Moreover, infants who encoded the object-location bindings with labels were not significantly better than those who did so in silence. These findings are discussed in the context of label advantages in cognition and auditory dominance.     

Teachers' and education students' perceptions of and reactions to children with and without the diagnostic label "ADHD"

Thirty-four elementary school teachers and 32 education students from Canada rated their reactions towards vignettes describing children who met attention-deficit/hyperactivity disorder (ADHD) symptom criteria that included or did not include the label “ADHD.” “ADHD”-labeled vignettes elicited greater perceptions of the child's impairment as well as more negative emotions and less confidence in the participants, although it also increased participants' willingness to implement treatment interventions. Ratings were similar to vignettes of boys versus girls; however, important differences in ratings between teachers and education students emerged and are discussed. Finally, we investigated the degree to which teachers' professional backgrounds influenced bias based on the label “ADHD.” Training specific to ADHD consistently predicted label bias, whereas teachers' experience working with children with ADHD did not.     

Children can solve Bayesian problems: the role of representation in mental computation

Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth, fifth, and sixth graders in terms of probabilities, their ability to estimate the Bayesian posterior probability was zero. Yet when the same information was presented in natural frequencies, Bayesian reasoning showed a steady increase from fourth to sixth grade, reaching an average level of 19, 39, and 53%, respectively, in two studies. Sixth graders' performance with natural frequencies matched the performance of adults with probabilities. But this general increase was accompanied by striking individual differences. More than half of the sixth graders solved most or all problems, whereas one third could not solve a single one. An analysis of the children's responses provides evidence for the use of three non-Bayesian strategies. These follow an overlapping wave model of development and continue to be observed in the minds of adults. More so than adults' probabilistic reasoning, children's reasoning depends on a proper representation of information.     

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。     

What’s in the name? Or how rocks and stones are different from bunnies and rabbits

Labels have been shown to play an important role in inductive generalization; however, the mechanism by which labels contribute to generalization early in development remains unclear. We investigated two factors that may influence the inductive potential of labels: semantic similarity and co-occurrence probability. Results suggested that adults and 6-year-olds rely on semantic similarity of labels and that their generalizations are not affected by co-occurrence probability. Specifically, generalization patterns were qualitatively similar for co-occurring semantically similar labels (e.g., bunny-rabbit) and non-co-occurring semantically similar labels (e.g., rock-stone) in 6-year-olds and adults. Unlike 6-year-olds and adults, 4-year-olds were likely to generalize co-occurring labels but not non-co-occurring labels. Possible mechanisms by which co-occurrence probability may influence label generalization in young children are discussed.     

Ontogenesis and Phylogenesis in the Analysis of Chinese Classifiers： Remarks on Philosophical Method

Philosophical analysis is commonly assumed to involve decomposing the meaning of a sentence or an expression into a set of conceptually basic constituent parts. This essay challenges this traditional view by examining the potential semantic roles that classifier phrases play in Chinese. It is suggested that the conceptual resources necessary for justifying claims about the semantical status of natural language classifier phrases should be informed in part by methods that accommodate ontogenic and evolutionary contexts. Evidence is provided for the view that many Chinese classifiers （but not all） are features regimented in the grammar of Chinese that have no functional role in normal adult communication, but which play an ontogenetic role in the child＇s development of linguistic competency. Furthermore, it is suggested that this ontogenetic role has features in common with the phylogenetic processes by which Chinese or its classical variants came about, as a later product of mechanisms that evolved in the species in accordance with varying demands for successful communication.     

心理差异量对儿童青少年分类活动影响的研究

本研究选择自制的、被试从前未看过的墨渍图为实验材料,探讨心理差异量对分类活动的影响。以４０名１１－２０岁儿童青少年为被试,一方面使用速示仪测量墨渍图之间的心理差异量,一方面要求被试对墨渍图进行自由分类,并说明理由。结果发现：①心理差异量直接影响分类结果。②心理差异量在１１岁、１４岁与１７岁、２０岁之间存在着非常显著的差异（Ｐ〈０．０１）。③分类标准的选择的年龄差异主要表现在分类标准的复杂性方面。     

On the (numerical) ranking associated with any finite binary relation

We generalize the concept of a ‘ranking associated with a linear order’ from linear orders to arbitrary finite binary relations. Using the concept of differential of an object in a binary relation as theoretical primitive, we axiomatically introduce several measurement scales, some of which include the generalized ranking as a special case. We provide a computational formula for this generalized ranking, discuss its many elegant properties and offer some illustrating examples.     

Motivated reasoning in the prediction of sports outcomes and the belief in the “hot hand”

The present paper explores the role of motivation to observe a certain outcome in people’s predictions, causal attributions, and beliefs about a streak of binary outcomes (basketball scoring shots). In two studies we found that positive streaks (points scored by the participants’ favourite team) lead participants to predict the streak’s continuation (belief in the hot hand), but negative streaks lead to predictions of its end (gambler’s fallacy). More importantly, these wishful predictions are supported by strategic attributions and beliefs about how and why a streak might unfold. Results suggest that the effect of motivation on predictions is mediated by a serial path via causal attributions to the teams at play and belief in the hot hand.
