Aggravated and mitigated opening utterances

Four types of aggravated opening utterances (insult, command, accusation, refusal without a reason) and four types of mitigated opening utterances (request, indication of shared responsibility, reaffirmation, and refusal with a reason) were investigated. Ordinary social actors rated each of the mitigated opening utterances higher than aggravated opening utterances on specific appropriateness, general appropriateness, and effectiveness. Hence, the type of opening employed to initiate an argumentative episode influences judgments of appropriateness and effectiveness.     

Logic of Knowledge and Utterance and the Liar

We extend the ordinary logic of knowledge based on the operator K and the system of axioms S₅ by adding a new operator U, standing for the agent utters , and certain axioms and a rule for U, forming thus a new system KU. The main advantage of KU is that we can express in it intentions of the speaker concerning the truth or falsehood of the claims he utters and analyze them logically. Specifically we can express in the new language various notions of lying, as well as of telling the truth. Consequently, as long as lying or telling the truth about a fact is an intentional mode of the speaker, we can resolve the Liar paradox, or at least some of its variants, turning it into an ordinary (false or true) sentence. Also, using Kripke structures analogous to those employed by S. Kraus and D. Lehmann in [3] for modelling the logic of knowledge and belief, we offer a sound and complete semantics for KU.     

《周易》形上思想研究

贞,从哲学来看,是一种善恶价值判断.它是对选择某项原则的赞叹与呼吁.它是主体的私意的表达.同时,这样的观点的接受意味着价值观的确立.价值观内化为主体的德性,成为人们行为的出发点,即元.价值判断的对象是对事实陈述的选择,如利.这些对象最终落实为知识形态.知识是一种相对确定的陈述.它无法表达存在的真正,即本体.知识所陈述的对象是事物的亨,即现象.现象是外在的生与主体的思的共同造作.在造作过程中,主体赋予事物以时空性.因此现象不真.事物的本体是生、思,即元.元展开为德性与生生不息.对于本体,人们保持沉默.元是无.不过,我们可以通过德行等把握它.     

儿童语言样本的分析技术

语言样本分析是评定儿童表达性语言能力发展的一个有效的广泛应用的方法,文章介绍了国外关于语言样本分析技术的发展情况,包括语言样本分析的程序、流行程度、语言样本的诱发方式,及其宏观结构和微观结构的分析指标;总结了国内在儿童语言样本分析领域的三方面的探索研究;未来的国内研究可以在宏观结构分析方面借鉴国外的经验,但在微观结构分析方面还需要基于汉语自身的特点,开发出适于中国儿童的语言样本分析指标。     

Modeling human dialogue with computers

Conversation, talk, the communicative process, can be compared to the symphonic play of a piece of music. There is an orchestra, the musicians, whose tones and notes must flow, complement and harmonize with one another. There is a main theme. As the music builds variations on the theme are played, and new themes and subthemes are introduced. The basinett responds to the strings, the bass emphasizes the mood of the violin, while the french horn adds a new melody. The subtlety and evenness of flow, the seeming simplicity of the piece, the rich interleaving of subdevelopments, variations, tangents, and recapitulations, are what make a piece of music great.Coherent communication is much the same. It looks easy. It flows. It seems effortless. In reality, of course, it is rich and complex, in both form and content. As in music, conversants may begin a conversation slowly, tentatively, with some simple (or complex) topic in mind. Slowly the momentum builds, the connections surface, and the themes become defined. As in music, these themes are then elaborated upon in various ways. Topic elaborations often spawn their own variations. New themes and subthemes are introduced. All the while, as in music, original themes reappear and are interwoven with the new ones. The twists and turns of the conversation seem to occur effortlessly.In music, there is usually one composer in control of which instrument plays next; one composer who is in charge of what the instrument will say. There is a single coordinator of theme introductions, developments, variations, and interweavings. The composition is done off-line and usually involves editing and re-editing for flaws. In discourse, however, we have on-line development with multiple parties responsible for flow coordination. All parties have to organize their own turns, themes, and variations, in addition to their being able to integrate these items into co-conversants'.In their book, Understanding Computers and Cognition, Winograd and Flores (1987) cite the following from Gadamer (Winograd and Flores, 1987, p. 32):It is not so much our judgments as it is our prejudices that constitute our being ... the historicity of our existence entails that prejudices, in the literal sense of the word, constitute the initial directedness of our whole ability to experience. Prejudices are biases of our openness to the world. They are simply conditions whereby we experience something — whereby what we encounter says something to us. (Gadamer, Philosophical Hermeneutics, 1976, p. 9)     

Dynamics of verbal interaction between interviewer and child in interviews with alleged victims of child sexual abuse

A number (n = 27) of investigative interviews with children were analyzed with a view to explore the verbal dynamics between interviewer and child. Different types of interviewer utterances and child responses were defined, and the interrelationships between these were explored. The effectiveness of different interviewer utterances in eliciting information from children as well as the type of utterance the interviewer used to follow up an informative answer by the child were investigated. Option-posing and suggestive utterances made up for more than 50% of interviewer utterances, the proportion of invitations being only 2%. Invitations and directive utterances were associated with an increase in informative responses by the child, the adverse being true for option-posing and suggestive utterances. Interestingly, even after the child had provided an informative answer, interviewers continued to rely on focused and leading interviewing methods--in spite of a slight improvement in interviewing behavior.     

Hesitation in communication: Does minority status delay responses?

Past studies indicated that people in a minority (vs. majority) position are slower to express their public/political opinion, and the larger the difference between the size of the two positions, the slower the response. Bassili termed this the minority‐slowness effect (MSE). In the current study, two experiments were conducted to demonstrate that MSE extends to people's understanding of utterances and explored the cognitive basis for this. Participants were asked to judge if an utterance is a ‘direct’ or an ‘indirect’ expression. The results show that participants in the minority (vs. majority) took longer to respond, and the larger the difference between the size of majority and minority, the longer the response latency (Study 1a). Furthermore, participants were aware of their own minority position (Study 1b). In Study 2, when participants were deprived of cognitive resources, MSE disappeared, presumably because participants lack the cognitive resources required to conform to utterance interpretation as favoured by the majority.     

Newborns discriminate utterance-level prosodic contours

Prosody is the fundamental organizing principle of spoken language, carrying lexical, morphosyntactic, and pragmatic information. It, therefore, provides highly relevant input for language development. Are infants sensitive to this important aspect of spoken language early on? In this study, we asked whether infants are able to discriminate well-formed utterance-level prosodic contours from ill-formed, backward prosodic contours at birth. This deviant prosodic contour was obtained by time-reversing the original one, and super-imposing it on the otherwise intact segmental information. The resulting backward prosodic contour was thus unfamiliar to the infants and ill-formed in French. We used near-infrared spectroscopy (NIRS) in 1-3-day-old French newborns (n = 25) to measure their brain responses to well-formed contours as standards and their backward prosody counterparts as deviants in the frontal, temporal, and parietal areas bilaterally. A cluster-based permutation test revealed greater responses to the Deviant than to the Standard condition in right temporal areas. These results suggest that newborns are already capable of detecting utterance-level prosodic violations at birth, a key ability for breaking into the native language, and that this ability is supported by brain areas similar to those in adults.

Research Highlights

• At birth, infants have sophisticated speech perception abilities.
• Prosody may be particularly important for early language development.
• We show that newborns are already capable of discriminating utterance-level prosodic contours.
• This discrimination can be localized to the right hemisphere of the neonate brain.
