Where Grammar and Interaction Meet: A Study of Co-Participant Completion in Japanese Conversation

This article examines the practice of "co-participant completion" in Japanese conversation, and explores what kinds of resources are mobilized to provide the opportunity to complete another participant's utterance-in-progress. It suggests the following observations as potential characteristics of Japanese co-participant completion: (i) Syntactically-defined two-part formats (e.g. [If X] + [then Y]) may not play as prominent a role as in English; (ii) The majority of cases of co-participant completion take the form of 'terminal item completion;' (iii) Locally emergent structures like 'contrast' and 'list' as well as 'unprojected' features of turn construction often play an important role in enhancing the opportunity for completing another participant's utterance-in-progress. The article then discusses the implications of these findings for the investigation of the mutual bearing of grammar and social interaction. In particular, the discussion focuses on what we can learn from the practice of co-participant completion about how projection of turn-shapes is accomplished in Japanese conversation.     

结构对称性汉语成语的认知研究

运用命名作业,从识别和再认两个方面探讨了结构对称性汉语成语的认知特点,结果发现：（１）成语识别有显著的结构对称效应和熟悉度效应;结构对称性成语的识别明显快于非对称性成语,高熟悉度成语的识别明显快于低熟悉度的成语。（２）成语再认的反应时有显著的结构对称效应,熟悉度效应不显著;而反应错误率则有显著的熟悉度效应,结构对称效应不显著。上述结果都不存在结构对称性和熟悉度之间的显著的交互作用。现有的西方拼音文字认知模型不能恰当地解释汉语成语的认知特点。     

Heuristics in learning classifiers: The acquisition of the classifier system and its implications for the nature of lexical acquisition

Classifiers are like nouns in that they classify entities in the world into lexical categories. However, the lexical nature of the classifier system is very different from that of nouns. We discuss how Japanese and Chinese children learn the meanings of classifiers. We focus on two specific questions: How classifier acquisition is different from noun acquisition; and what the prerequisites are for spontaneously extracting the meanings of classifiers. It is shown that children are very conservative in assigning meaning to classifiers. The pace of learning largely depends on semantic complexity, across languages and within each language. Furthermore, we suspect that learning the meanings of classifiers requires a certain cognitive ability – an ability to synthesize pieces of partial knowledge and form them into a cohesive whole. It may be only when children have developed such an ability that they are able to extract the complex semantic rules of classifiers on their own. We conclude that children take very different routes in learning nouns and classifiers: Unlike noun acquisition, classifier acquisition is guided by a slow, bottom-up process.     

Argument Status and PP-Attachment

Prepositional phrase attachment was investigated in temporarily ambiguous sentences. Both attachment site (noun phrase or verb phrase) and argument status (argument or adjunct) were manipulated to test the hypothesis that arguments are processed differently than adjuncts. Contrary to this hypothesis, some previous research suggested that arguments and adjuncts are initially processed in the same manner, following a general bias to attach prepositional phrases to the verb phrase whenever possible [Clifton, Speer, & Abney (1991) Journal of Memory and Language, 30, 251–271]. The current study supports the hypothesis for differential processing, even during the initial stages of syntactic analysis. In an eye movement experiment, readers spent less first-pass time on argument prepositional phrases (PPs) than adjunct PPs. The results support a view in which a noun’s or verb’s argument structure can facilitate the analysis of its arguments.This research was supported by NSF grants SBR-9729056 and SBR-9720473 to the first author. We gratefully thank Gerry Altmann, Rick Lewis, Brian McElree, Don Mitchell, Neal Pearlmutter, Shari Speer, and Suzanne Stevenson for useful discussions and helpful comments. We would also like to acknowledge the Rutgers University Center for Cognitive Science, where the eye movement data were collected and an initial draft of the paper was written.     

Applicability of the Somatomorphic Matrix computer program in Japanese and Australian Caucasian males in relation to measured body composition

The Somatomorphic Matrix (SM) is a computer-based body image assessment program that allows assessment of the individual's body image in relation to known body composition values. To date, no study has compared the SM results to the measured body composition and assessed the usefulness in multi-ethnic samples. Japanese and Australian Caucasian males underwent testing to examine the SM body image results to their measured body composition. Japanese males showed significant (p < 0.01) discrepancy in their measured and the perceived ‘current’ muscularity compared with Australians. Both groups showed wide variability in the perception of their ‘current’ body composition in relation to the measured values, indicating an incomparability of the SM results to the measured results. The study also showed Japanese males to have lower consistency in the SM results than Australian males after a 12-month interval. In order to use the program in multi-ethnic populations further development of the program is recommended.     

The influence of Japanese mothers' styles of emotional expression on thirteen-month-old infants' reactions to a stranger

The present study investigated the hypothesized influence of mothers' styles of emotional expression on infants' responses to the stranger in Episode 3, the Ainsworth Strange Situation. One hundred and thirty-five mothers volunteered for this experiment with their 13-month-olds. The mothers' answers on an expression style questionnaire (EESQ) were factor analysed. According to their mothers' factor scores, infants were divided into four groups, those having (a) expressive type mothers (N = 40), (b) suppressive type mothers (N = 39), (c) positive expressive type mothers (N = 31), and (d) negative expressive type mothers (N = 25). The infants' behaviours were analysed in 5-sec intervals. The infants having expressive type mothers showed a strong interest in the stranger and interacted with her willingly. The infants having suppressive type mothers exhibited less smiling and much freezing behaviour. The infants having positive expressive type mothers reacted with more smiling, much bodily contact behaviour with the mother and less crying. The infants having negative expressive type mothers showed more often crying and frequent head orientation towards the stranger.     

熟练汉-英双语者的语码切换机制—— 来自短语水平的证据

以熟练汉-英双语者为被试, 考察了在短语水平上语码切换的机制及切换代价的来源。结果表明：(1)汉语与英语表示空间方所的短语的差异和表示量的短语的对应与否影响语码切换过程, 但对于两种语言的切换代价的影响不显著, 表明语码切换代价未受特定语言的语法特征影响; (2)熟练汉-英双语者在短语水平上表现出语码切换代价的不对称性：切换至熟练语言的代价比切换至非熟练语言的代价大; (3)熟练汉-英双语者的切换代价源于两种语言短语的激活和竞争, 支持非特定语言选择假说, 可以用抑制控制模型来解释。整个研究表明, 熟练双语者的语码切换代价源于语言表征系统之外。     

Bomb threats and offender characteristics in Japan

This study examined telephone bomb threats and offender characteristics in Japan (N = 101). The results showed that the most frequent offenders were middle‐aged men (mean 42.6 years), motivated by desire for money (46%), resentment (26%), or diversion (24%). In the case of female offenders, most were connected with the targets (83%). Categorical principle component analysis and hierarchical cluster analysis differentiated the offenders into three themes. ‘Instrumental’ offenders telephoned the target directly (e.g. a bank or department store), demanding money by public phone. ‘Expressive/affective’ offenders motivated by resentment telephoned from their home and almost never had a criminal record. ‘Expressive/cognitive’ offenders motivated by diversion targeted railways and mostly telephoned emergency numbers.
