The Logical Structure of Linguistic Commitment III Brandomian Scorekeeping and Incompatibility

Curiously, though he provides in Making It Explicit (MIE) elaborate accounts of various representational idioms, of anaphora and deixis, and of quantification, Robert Brandom nowhere attempts to lay out how his understanding of content and his view of the role of logical idioms combine in even the simplest cases of what he calls paradigmatic logical vocabulary. That is, Brandom has a philosophical account of content as updating potential – as inferential potential understood in the sense of commitment or entitlement preservation – and says that the point of logical vocabulary is to make available the expressive resources to make explicit such semantic structures as arise from discursive scorekeeping practice. Thus, one would expect an account of the updating or inferential potential of sentences involving logical vocabulary, an account which is such as to assign to those sentences the inferential significance necessary for this expressive job. In short, one would expect a semantics of logical vocabulary – &, , – in terms of the difference an assertion of a sentence involving it makes to the atomic score of a linguistic agent, and a completeness proof for the logic generated by this semantics. Despite this, no such semantics is given in MIE. It is in the current paper.     

Pragmatic connectives,argumentative coherence and relevance

This article is concerned with pragmatic connectives and their uses in discursive argumentation. Three approaches to pragmatic connectives will be presented: (1) argumentation theory, which implies a conception of pragmatics integrated within semantics, and a specific type of argumentative rules, called topoi; (2) discourse structure theory, which associates a function in the structuring of discourse sequences to pragmatic connectives; (3) relevance theory, which constitutes a cognitive pragmatic theory, in which no specific principle is associated to linguistic items. However, two main functions to pragmatic connectives can be proposed: the facilitation of inferences, and the access to relevance. The final purpose of this article is to indicate how argumentative effects in discourse can be explained in a cognitively-based pragmatic theory.     

Begging what is at issue in the argument

This paper objects to treating begging the question as circular reasoning. It argues that what is at issue in the argument is not to be confused with the claim or position that the arguer is adopting, and that logicians from Aristotle on give the wrong definition and have difficulty making sense of the fallacy because they try to define it in terms of how an argument is defined by logical theory - as a sequence consisting of premises followed by a conclusion. That the problematic about begging the question depends on treating an argument as a context-less sequence of statements seems to be anticipated by the pragma-dialectical approach. The paper offers a critique of this dialogical approach, as exemplified by Douglas Walton in his recent book on begging the question, on the grounds that it raises more problems than it solves. It concludes with the suggestion that what is really at issue in discussions of begging the question is the need for a theory of fallacy.     

The Construction of Issues: Pleading Theory and Practice, Relevance in Pragmatics, and the Confrontation Stage in the Pragma-Dialectical Theory of Argumentation

Legal theory and practice, particularly on the exchange of pleadings, are referred to as a means of examining current thinking in pragmatics on relevance. The rules of pleadings suggest that the concept of relevance as used in pragmatics is emptied of any meaning and that theories of argumentation have not sufficiently taken into account the preliminary construction which issues to be argued about require.     

Apocalyptic relevance

In their book, Relevance, Sperber and Wilson make an important contribution towards constructing a credible theory of this unforthcoming notion. All is not clear sailing, however. If it is accepted as a condition on the adequacy of any account of relevance that it not be derivable either that nothing is relevant to anything or that everything is relevant to everything, it can be shown that Sperber and Wilson come close to violating the condition.     

CE is Not a Conservative Extension of E

The logic CE (for Classical E) results from adding Boolean negation to Anderson and Belnap"s logic E. This paper shows that CE is not a conservative extension of E.     

线索靶子关联和搜索策略对注意捕获的作用——来自意义线索的证据

采用线索化范式,操作性地建立线索和靶子间的关联,通过比较不同搜索策略任务下不同线索靶子关联条件间的捕获量考察关联水平及搜索策略对注意捕获的作用,并分析抽象的意义概念对空间注意分配的调节作用。结果发现(1)意义线索的注意捕获符合关联性的注意定向假说,只有符合当前注意控制定势的线索才具有捕获注意的能力;(2)知觉关联在调节无意注意定向上具有主导性,调节能力强,能将其他因素效应掩盖;语义关联单独作用时对无意注意定向有调节作用,但调节程度小,效应易被掩盖;(3)搜索策略虽然能够大大提高反应速度,但只有基于特征独子的搜索模式对无意注意定向有调节作用,且调节能力有限。研究再次认证了空间无意注意转移中注意控制定势的作用,同时指出抽象的概念加工能够根据当前的环境有效指导后续的选择和行为。     

Atom Exchangeability and Instantial Relevance

We give an account of some relationships between the principles of Constant and Atom Exchangeability and various generalizations of the Principle of Instantial Relevance within the framework of Inductive Logic. In particular we demonstrate some surprising and somewhat counterintuitive dependencies of these relationships on ostensibly unimportant parameters, such as the number of predicates in the overlying language.

句法歧义句理解加工中的语义关联性效应研究

通过实验探讨了汉语直接宾语(DO)/宾语小句(SC)类暂时句法歧义句理解加工中的语义关联性效应。实验采用自定速动窗技术。实验1发现在汉语暂时句法歧义句理解加工中存在语义关联性效应。实验2发现语义关联性与句法歧义性因素在解歧区产生了显著的交互作用。结果表明,语义关联性因素显著影响对句子的理解加工,并且与句法歧义因素共同作用于句子的理解加工过程。
