动词信息在汉语句子加工早期的作用

研究控制了汉语句子的及物动词与其直接宾语之间的搭配合适程度,分别利用听觉词汇监控和眼动技术,研究了动词的“宾语选择性限制信息”在句子加工早期的作用。实验发现动词与宾语搭配上的各种违反对目标名词（宾语）的加工产生了即时效应。结果表明,包括语义信息在内的各种词汇信息被通达后立即参与了汉语句子加工。     

句法和语义在汉语简单句理解中的作用

两个实验探讨句法和语义在汉语简单句加工中的作用及其相互关系。实验一采用施事判断任务,发现句法作用与语义可逆性的作用都很显著;实验二采用快速句子判断任务,发现句法作用是主要的,语义可逆性无显著作用;两个实验都发现句法与语义可逆性之间的交互作用不显著。这些结果表明：（１）在汉语简单句理解的过程中句法因素的作用是主要的,语义因素的作用是次要的,只要当实验任务更多地强调语义分析时,语义因素才有显著的作用。     

On the Logical Positivists' Theory of Truth: The Fundamental Problem and a New Perspective

The present article purports to show that the protocol sentence debate, pursued by some leading members of the Vienna Circle in the mid-1930s, was essentially a controversy over the explanation and the real significance of the concept of truth. It is further shown that the fundamental issue underlying the discussions about the concept of truth was the relationship between form and content, as well as between logic/language and the world. R. Carnap was the philosopher who most explicitly and systematically attempted to come to grips with this problem. It is shown that the form-content distinction pervades the three most important phases of Carnap's philosophical development: the structuralist (in Der logische Aufbau der Welt), the syntactical and the semantical. His final semantical stance is essentially determined by the concept of linguistic frameworks. The article purports to demonstrate that this concept cannot be dispensed with in philosophy, but that Carnap failed to work out its ontological implications. Finally, the concept of an internal ontology is briefly delineated. This revised version was published online in August 2006 with corrections to the Cover Date.     

On the meaning of statistical interactions

The problems which can arise in predicting the presence or absence of statistical interactions when a theoretical model is not set into correspondence with the experimental design model are considered in the context of a specific study of developmental differences in distractibility. It is concluded that intuitive or incomplete theoretical analyses often lead to incorrect prediction concerning statistical interactions and to spurious or ambiguous conclusions based on the confirmation or disconfirmation of those predictions and that the analysis of the relationship between a theoretical model and the experimental design model will offer considerable protection against such undesirable outcomes.     

Children's size judgments when size and distance vary: Is there a developmental trend to overconstancy?

A review of the experimental literature on size constancy in children shows that studies permitting unrestricted viewing in natural settings provide only limited support for the hypothesis, proposed by Wohlwill, of a developmental trend from under- to overconstancy. A study is reported in which subjects aged 8 to 18 years made magnitude estimations of height for targets whose height and distance from them varied. For distances up to 15 m, and heights from 5 to 50 cm, size constancy prevailed at all ages: The same number was assigned to a given height at every distance. If a developmental trend exists, it requires either younger subjects or greater distances to be revealed.     

Three conditions on conceptual naturalness

Human infants are predisposed to organize their experience in terms of certain concepts and not in terms of others. The favored concepts are called natural, the remainder, unnatural. A major problem in psychology is to state a principled distinction between the two kinds of concepts. Toward this end, the present paper offers three, formal necessary conditions on the naturalness of concepts. The conditions attempt to link the problem of naturalness to the distinctions between sense versus nonsense, simplicity versus complexity, and validity versus invalidity.     

Pauses and syntax in American sign language

Research on spoken languages has shown that the durations of silent pauses in a sentence are strongly related to the syntactic structure of the sentence. A similar analysis of the pauses (holds) in a passage in American Sign Language reveals that sequences of signs are also interspersed with holds of different lengths: long holds appear to indicate the ends of sentences; shorter holds, the break between two conjoined sentences; and the shortest holds, breaks between internal constituents. Thus, pausal analysis is a guide to parsing sentences in ASL.     

Structured propostions and sentence structure

It is argued that taken together, two widely held claims ((i) sentences express structured propositions whose structures are functions of the structures of sentences expressing them; and (ii) senteces have underlying structures that are the input to semantic interpretation) suggest a simple, plausible theory of propositional structure. According to this theory, the structures of propositions are the same as the structures of the syntactic inputs to semantics they are expressed by. The theory is defended against a variety of objections.I have benefitted from discussions with Michael Jubien, Michacl Liston, Paul Teller, Howard Wettstein, Mark Wilson and especially David Copp. The comments of Mark Richard and an anonymous referee for Journal of Philosophical Logic on an earlier draft resulted in a much improved paper. Various circumstances resulted in this paper appearing after King [1995], though the latter was written later and amends the present view in several ways. See notes 9, 13, 15 and 33 of King [1995].     

Self-directed activity and cognitive development

Both in constructivist theories of development and in educational applications of such theories, self-directed activity is aleged to play a critical role in the developmental process. The purpose of the present study was to subject this popular assertation to empirical examination. Subjects were fourth- and fifth-graders who showed no formal operational reasoning. Subjects assigned to an experimental condition were matched with yoked-control partners of the same sex and grade. An additional group of subjects was assigned to a simple control condition. Experimental and yoked-control subjects were given opportunities to solve problems requiring formal operational reasoning over a three-month period. The procedure for experimental subjects differed from that for yoked-controls only in that experimental subjects selected the particular information-seeking activities they would engage in. Yoked-control subjects carried out the same activities that had been chosen by their experimental partners. Both groups showed significant progress in the construction of new reasoning strategies, but experimental subjects showed greater progress than yoked-controls. The enhanced progress of the experimental subjects, it is suggested, was due to the increased presence of anticipatory schemes regarding the outcomes of their actions. These anticipatory schemes allowed subjects to better “make use of”, in the cognitive sense—in other words, assimilate into a theoretical framework—the data yielded by the experiments, and thus they gained more from their experience.
