In [1], D. W. Hart and C. Mcginn considered two logics A1 and A2. These logics embody part of a tradition about a priori knowledge and necessity. They proved that A2 is a conservative extension of a well-known modal logic S5 but left the problem whether A1 is a conservative extension of S4 open. In this note, we shall show that A1 is not a conservative extension of S4 but of S5, and also correct an inadequate proof. 相似文献

In this paper, we present a discussion game for argumentationunder stable semantics. Our work is inspired by Vreeswijk andPrakken, who have defined a similar game for preferred semantics.In the current paper, we restate Vreeswijk and Prakken's workusing the approach of argument labellings and then show howit can be adjusted for stable semantics. The nature of the resultingargument game is somewhat unusual, since stable semantics doesnot satisfy the property of relevance. 相似文献

This article reports a study carried out in order to measure how semantic factors affect reductions in the difficulty of the Chinese Ring Puzzle (CRP) that involves removing five objects according to a recursive rule. We hypothesised that semantics would guide inferences about action decision making. The study involved a comparison of problem solving for two semantic isomorphic variants of the CRP ( fish and fleas ) with problem solving for the puzzle's classic variant (the Balls and Boxes problem; Kotovsky & Simon, 1990). Our results showed that the number of moves was reduced by 47% in the fish version and by 51% in the flea version. We discuss these results in terms of semantic inferences and reductions in relational complexity. During the exploratory stage of problem solving participants discover the dependent relations between elements in the puzzle. Initially these relations are processed separately; learning involves generalising the relations within a coherent, interconnected whole that makes up the puzzle's rules. It seems that semantics make it easier for the puzzle's elements to be grouped together within coherent, meaningful wholes, which reduces relational complexity and facilitates problem solving. 相似文献

The effects of relational stage, intimacy, and gender on touch were examined. Participants were 270 partners from 135 couples involved in a heterosexual romantic relationship. Results indicated that touch varies as a function of relational stage. An examination of relational stage and subjects' perceptions of how much they touched their partner and how much their partner touched them generally indicated an asymptotic relationship. Specifically, men's and women's perceptions of how much they touched their partners, and women's perceptions of how much their partners touched them, increased from the casually dating to the seriously dating stage and then leveled off for seriously dating, engaged, and married couples. Men's perceptions of how much their partners touched them increased from the casually dating to the seriously dating stage then decreased from the seriously dating to the married stage. Relational intimacy was also curvilinearly related to self and partner perceptions of touch. Because there were no significant interaction effects between stage and gender, or intimacy and gender, the curvilinear effects of relational stage and intimacy on touch are generalizable to both men and women. 相似文献

Research on shallow processing suggests that readers sometimes encode only a superficial representation of a text and fail to make use of all available information. Greene, McKoon, and Ratcliff (1992) extended this work to pronouns, finding evidence that readers sometimes fail to automatically identify referents even when these are unambiguous. In this paper we revisit those findings. In 11 recognition probe, priming, and self-report experiments, we manipulated Greene et al.'s stories to discover under what circumstances a pronoun's referent is automatically understood. We lengthened the stories from 4 to 8 lines. This simple manipulation led to automatic and correct resolution, which we attribute to readers' increased engagement with the stories. We found evidence of resolution even when the additional text did not mention the pronoun's referent. In addition, our results suggest that the pronoun temporarily boosts the referent's accessibility, an advantage that disappears by the end of the next sentence. Finally, we present evidence from memory experiments that supports complete pronoun resolution for the longer but not the shorter stories. 相似文献

In a recent article, Fagot proposed a generalized family of coefficients of relational agreement for multiple judges, focusing on the concept of empirically meaningful relationships. In this paper an ordinal coefficient of relational agreement, based on ranking data, is presented as a special case of the generalized family. It is shown that the proposed ordinal coefficient encompasses other ordinal coefficients, such as the Kendall coefficient of concordance, the average Spearman rank-order coefficient, and intraclass correlation based on ranks. It is also shown that the Kendall coefficient of concordance, corrected for chance agreement, is equivalent to the ordinal coefficient proposed in this paper. 相似文献

The present paper describes the computer aspects of a reaction time experiment with couples. The hardware consists of two computers connected through a local area network. Issues that deal with the first PC include timing routines, screen control, mice data decoding, and synchronization of computer software—written in Assembler for a PC without hard disk—with information presented in a videotape. The second computer was used for data processing that was written in VBA. Although the system was created for a dedicated purpose, it is easily applicable to other environments. 相似文献

Concluding remarks Our program is ambitious, as is any attempt to match life (in our case real science) with virtue (e.g., exactness). We want our semantics to be not only simia mathematicae but also ancilla scientiae: built more geometrico and at the same time relevant, nay useful, to live science. The goal of exactness may sound arrogant but is actually modest, for the more we rigorize the more we are forced to leave out of consideration, at least for the time being. As to the service intention: we should try to be of some help to science because the latter faces semantic problems but has no tools of its own for solving them. If it had such tools scientists would not engage in spirited polemics over matters of sense and reference, as they often do. Witness the debates on whether the relativistic and quantum theories are concerned with sentient observers, whether population genetics refers to populations taken as wholes, whether psychology is actually concerned with the brain, and whether the sense of a theory is excreted by its mathematical formalism or is determined by the way the theory is tested.A semantics of science should help settle these and similar issues. Moreover it should give sound advice as to how to formulate scientific theories so as to avoid such imprecisions and ambiguities as may give rise to debates of the kind. Constructing such a semantics, both exact and relevant to science, should be more rewarding than either manufacturing neat but irrelevant theories or pursuing erratic polemics on meaning and meaning changes.
