语句重音分布模式知觉

在排除语义和句法结构信息的情况下,用统计方法研究听者使用局部的韵律学线索知觉语句重音分布模式的能力;并根据知觉模式,讨论汉语中重音分类、词重音在语流中的变化以及重音在语句组织和语义表达中的作用等问题。     

汉语歧义句的加工

通过两个实验,对汉语歧义句多种解释的意义频率和语境位置在句子歧义解析过程中的效应进行了考察。实验结果表明：（１）前语境为被试提供了某种预期信息,它对句子歧义解析的效应大于后语境;（２）在句子歧义解析过程中,不管有语境或无语境,不管是前语境或后语境,被试提取歧义句的主要意思比提取次要意思快;（３）歧义句的多种解释的激活,有一个时间进程,在短延迟间隔条件下,歧义句的主要意思可以被激活并形成表征,但次要意思的激活和表征则需要较长的时间     

汉语句子可继续性对句子理解加工的即时影响

通过操纵动词与后接词的关系,来产生搭配异常并控制句子的可继续性,研究汉语词汇信息在句子加工中的即时作用。实验一利用跨通道技术,发现动一名词搭配异常对目标名词的加工有即时影响,形容词条件下可继续性对目标形容词的加工有即时影响;实验二采用眼动技术,发现名词条件和形容词条件下可继续性均有显著的即时影响。结果显示,语义等多种词汇信息被通达后立即共同参与了汉语句子加工。     

THE TRUTH OF TRIPARTITION

Since the arguments that Plato provides in the Republic for the thesis that the human soul consist of three parts (reason, spirit, appetite) are notoriously problematic, I propose other reasons for accepting tripartition: reasons that we too could endorse, or at least entertain with some sympathy. To wit, (a) the appetitive part of Plato's divided soul houses desires and tendencies we have because we are animal bodies programmed to survive (as individuals and as a species) in disequilibrium with a variegated, often varying environment, (b) the spirited middle part houses status concerns that belong to us as social animals, while (c) what makes us rational animals is a faculty of reason, conceived in strikingly non-Humean terms, which determines what is best all things considered. Other psychic tendencies may then be explained in terms of the education and mutual interaction of the three parts we are 'programmed' for from birth.     

印尼语主动句、被动句的命题表征项目顺序特点

采用句子—图形验证任务(sentence-pictureverificationtask)探讨了印尼学生理解印尼语主动句、被动句所形成的命题表征中的项目顺序的特点。实验结果表明,无论是语义水平较高的不可逆句,还是语义水平较低的可逆句,印尼学生理解印尼语主动句和被动句后所建构的命题表征中项目顺序均为“受事→施事”。本研究结果初步表明,印尼学生理解印尼语主动句和被动句时,能根据它们不同的表层结构(印尼语主动句的语言表达顺序为“施事→受事”、印尼语被动句的语言表达顺序为“受事→施事”)建构相同的深层结构(语义内容的命题表征项目顺序“受事→施事”),可能是一个按照“受事→施事”固定方向进行的系列认知心理加工的过程。     

SUPERVALUATION FIXED-POINT LOGICS OF TRUTH

Michael Kremer defines fixed-point logics of truth based on Saul Kripke’s fixed point semantics for languages expressing their own truth concepts. Kremer axiomatizes the strong Kleene fixed-point logic of truth and the weak Kleene fixed-point logic of truth, but leaves the axiomatizability question open for the supervaluation fixed-point logic of truth and its variants. We show that the principal supervaluation fixed point logic of truth, when thought of as consequence relation, is highly complex: it is not even analytic. We also consider variants, engendered by a stronger notion of ‘fixed point’, and by variant supervaluation schemes. A ‘logic’ is often thought of, not as a consequence relation, but as a set of sentences – the sentences true on each interpretation. We axiomatize the supervaluation fixed-point logics so conceived.     

词边界信息在句中的分布

用经过删除的语音歧义句作材料,研究了词边界信息在句中的分布。结果说明,在歧义句中歧义音节是最重要的切分线索;向歧义音节的前后过渡也对词切分有贡献;歧义音节和过渡以外的部分在一定条件下对切分有帮助。     

句子重音对汉语同音异义词的解歧作用

通过针对包含两对汉语同音异义词(“qui(4)shi(4)”(“趣事”或“去世”和“sheng(1)xue(2)”(“声学”或“升学”))的10个发音人语料的声学特征分析和知觉实验,结果发现：消除这两对同音异义词歧义的不是词重音而是句子重音。这个研究结果说明：汉语中句子重音能够通过选择强调同音异义词的某个音节来消除它们的歧义。
