This paper investigates scalar implicatures and downward entailment in child English. In previous experimental work we have shown that adults’ computation of scalar implicatures is sensitive to entailment relations. For instance, when the disjunction operator or occurs in positive contexts, an implicature of exclusivity arises. By contrast when the disjunction operator occurs within the scope of a downward entailing linguistic expression, no implicature of exclusivity is computed. Investigations on children’s computation of scalar implicatures in the same contexts have led to (...) a slightly different picture. In particular it has proven difficult to demonstrate that children compute scalar implicatures (in non- downward entailing contexts) using the Truth Value Judgment task, a technique that has been used successfully in showing children’s sensitivity to other semantic phenomena. Adopting a different experimental technique called the Felicity Judgment task, however, we demonstrated children’s knowledge of the prerequisites to the computation of scalar implicatures (Chierchia, Crain, Guasti, Gualmini and Meroni, 2001).

In recent years there has been a great deal of interaction among game theorists, philosophers, and logicians in certain foundational problems concerning rationality, the formalization of knowledge and practical reasoning, and models of learning and deliberation. This unique volume brings together the work of some of the preeminent figures in their respective disciplines, all of whom are engaged in research at the forefront of their fields. Together they offer a conspectus of the interaction of game theory, logic, and epistemology in (...) the formal models of knowledge, belief, deliberation, and learning and in the relationship between Bayesian decision theory and game theory, as well as between bounded rationality and computational complexity.

An important debate in the current literature is whether “all truth-conditional effects of extra-linguistic context can be traced to [a variable at; LM] logical form” (Stanley, ‘Context and Logical Form’, Linguistics and Philosophy, 23 (2000) 391). That is, according to Stanley, the only truth-conditional effects that extra-linguistic context has are localizable in (potentially silent) variable-denoting pronouns or pronoun-like items, which are represented in the syntax/at logical form (pure indexicals like I or today are put aside in this discussion). According to (...) Recanati (‘Unarticulated Constituents’, Linguistics and Philosophy, 25 (2002) 299), extra-linguistic context can have additional truth-conditional effects, in the form of optional pragmatic processes like ‘free enrichment’. This paper shows that Recanati’s position is not warranted, since there is an alternative line of analysis that obviates the need to assume free enrichment. In the alternative analysis, we need Stanley’s variables, but we need to give them the freedom to be or not to be generated in the syntax/present at logical form, a kind of optionality that has nothing to do with the pragmatics-related optionality of free enrichment.

In contemporary science uncertainty is often represented as an intrinsic feature of natural and of human phenomena. As an example we need only think of two important conceptual revolutions occurred in physics and in logic during the first half of the twentieth century: (a) the discovery of Heisenberg’s uncertainty principle in quantum mechanics; (b) the emergence of the many-valued logical reasoning, which gave rise to the so-called fuzzy thinking. We discuss the possibility of applying the notions of uncertainty , developed (...) in the framework of quantum mechanics, quantum information and fuzzy logics, to some problems of political and social sciences.

This paper investigates young children's knowledge of scalar implicatures and downward entailment. In previous experimental work, we have shown that young children access the full range of truth-conditions associated with logical words in classical logic, including the disjunction operator, as well as the indefinite article. The present study extends this research in three ways, taking disjunction as a case study. Experiment 1 draws upon the observation that scalar implicatures (SIs) are cancelled (or reversed) in downward entailing (DE) linguistic environments, e.g., (...) in the scope of negation (Chierchia, 2000). Experiment 2 was designed to determine if scalar implicatures are used by children, like adults, to influence the interpretation of disjunction in non-DE contexts, yielding an implicature of exclusivity for disjunction. Whereas adult controls always rejected assertions of the form A or B in positive (non-DE) contexts in which assertions of the form A and B were also true, many children accepted assertions with disjunction in such contexts. To provide an interpretation to the findings from Experiment 2, a new experimental technique was devised and used in Experiment 3. The new technique presents pairs of assertions to children, who are asked to judge which assertion is a ‘better’ description of the context. The findings from Experiment 3 demonstrated children's awareness that A and B is more informative than A or B in positive contexts, where both statements are true. Taken together, the findings of Experiments 2 and 3 are compatible with the view that some children lack the computational resources to apply scalar implicatures when a single assertion is presented alone (see Reinhart, 1999).

This article addresses the problem of emergence through a distinction, often neglected in the literature, between two different aspects of this issue: (1) the theoretical problem of providing modelizations able to explain the expression of emergent properties; (2) the epistemological problem of warranting the scientific value of the emergentist descriptions of nature. This paper considers this double issue with regard to the biological domain, and proposes a double solution (theoretical and epistemological) originally developed in early studies on self-organization. The underlying (...) hypothesis is that this solution offers the current biological emergentism the opportunity of developing a coherent structure: matching consistently the theoretical and the epistemological frames of the research, that is, coupling the emergentist conception of life with an emergentist conception of science.

In a message posted to one of the cognitive science discussion groups the author asked, to paraphrase roughly, what should be read to get an up-to-date account of research into color naming? My advice is (and was) to consider the two books under review here: C. L. Hardin and Luisa Maffis excellent collection of essays on color language research; Robert MacLaurys magnum opus on color naming and cognition.
A course in professional ethics for civil engineers was taught for the first time in Spain during the academic year 2007/08. In this paper a survey on the satisfaction and expectation of the course is presented. Surprisingly the students sought moral and ethical principles for their own ordinary lives as well as for their profession. Students were concerned about the law, but in their actions they were more concerned with their conscience, aware that it can be separate from the law.
This article takes a linguistic perspective of argumentation, as proposed by Marion Carel and Oswald Ducrot with the “Théorie des blocs sémantiques” (SBT: Semantic Block Theory). This theory argues that the meaning of a linguistic entity is determined by a collection of discourses that this entity calls to mind. Describing the meaning of a word, a syntagm or an utterance amounts to specifying the argumentative linkages (“enchaînements argumentatifs”) allowed by these entities. We propose a semantic and argumentative analysis of syntagms (...) mujer fácil , femme facile [easy woman] and hombre fácil , homme facile [easy man] that, in Romance languages in particular, hold different meanings: both hombre fácil/homme facile describe a man’s character or nature, whereas mujer fácil/femme facile, in their most common usage, imply a certain sexual behavior. We will compare the argumentative linkages that make up the meaning of mujer fácil/femme facile with those of other expressions that are part of the same semantic block. Also, this analysis will connect the proposed description to certain proverbial discourse about women, and it will call attention to the role that these expressions can play in a persuasive strategy.

In an article published in 2003, Klaus Jacobi—using texts partially edited in De Rijk's Logica Modernorum—demonstrated that twelfth-century logic contains a tradition of reflecting about some of the transcendental names (nomina transcendentia). In addition to reinforcing Jacobi's thesis with other texts, this contribution aims to demonstrate two points: 1) That twelfth-century logical reflection about transcendental terms has its origin in the logica vetus, and especially in a passage from Porphyry Isagoge and in Boethius's commentary on it. In spite of the (...) loss of the major part of the Aristotelian corpus, the twelfth-century masters in logic still received some Aristotelian theses concerning the notions of one and being via Porphyry and Boethius; on the basis of such theses, they were able to elaborate a sort of proto-theory of the transcendentals as trans-categorical terms. 2) That this theory is centred on the idea that there exists a particular group of names which have the property that they can be said of everything; this group includes "being", "one", "thing" and "something" (ens, unum, res, aliquid). Twelfth-century masters in logic try to question the (originally Aristotelian) thesis that these terms are equivocal, although they do not deny it completely. (shrink)
This paper investigates the influence of contrastive stress in resolving potential semantic ambiguities. The sentences under investigation contain the focus operator only. Sentences with only have three main properties: (a) some sentential element is typically in focus, (b) the speaker presupposes that a set of alternatives to the focus element (the contrast set) has previously been introduced in the context; and (c) the speaker makes the assertion that the focus element has some unique property which other members of the reference (...) set lack. Previous literature on focus has concluded that stress plays a role in the interpretation of only-sentences in many natural languages, including English (Rooth, 1992). In processing terms, this suggests that contrastive stress could immediately determine which NP bears the semantic focus (and therefore the NP that presupposes a contrast set in the context). On this scenario, the processing cost associated with contrastive stress should be no greater than the cost associated with neutral stress. There is, however, a theoretically motivated proposal that makes the opposite prediction (Reinhart, 1999). As we understand it, in this model the parser is expected calculate default stress first, with its associated interpretation, and only later reanalyze the sentence, if necessary, based on the contrastive stress pattern. Since in English the default stress falls on the last NP of the sentence, any deviation from this pattern will be more costly. In processing sentences with contrastive stress, the model implies that the parser first calculates the interpretation that is associated with the default stress pattern. In this regard, young children’s interpretation of sentences with stress and the focus operator only is of special interest. Because young children are in the throes of grammar formation, their behavior can reveal default strategies for sentence processing, as well as the extent to which the parser’s sensitivity to contrastive stress is universal, i.e., includes child languages..

Many experimental investigations of human sentence processing have shown that listeners do not wait until they reach the end of a sentence before they begin to compute an interpretation. Rather, listeners incrementally make commitments to an interpretation as the linguistic input unfolds in real time. A consequence of this property of sentence comprehension is that it sometimes gives rise to so-called garden-path effects. In the presence of a temporary ambiguity, listeners may assign an interpretation that later turns out to be (...) unviable and must, therefore, be abandoned in favor of an alternative interpretation. Various explanations have been proposed to account for garden- path effects that have been documented in certain experimental contexts (Frazier and Rayner, 1982; Trueswell and Tanenhaus, 1994; MacDonald, 1994, among others). One line of research has claimed, however, that the referential contexts in which sentences ordinarily appear often mitigate, or even completely eliminate, garden-path effects. This is the Referential Theory proposed by Crain and Steedman (1985) and extended by Altmann and Steedman (1988). According to the Referential Theory, people experience garden-path effects primarily when sentences are interpreted outside any referential context or in infelicitous contexts. If the Referential Theory is correct, garden-path effects are largely experimental artifacts. Recent work by Trueswell, Sekerina, Hill and Logrip, (1999) suggests that children might not be sensitive to features of the referential context to the same.. (shrink)

Euthanasia has become the subject of ethical and political debate in many countries including Mexico. Since many physicians are deeply concerned about euthanasia, due to their crucial participation in its decision and implementation, it is important to know the psychological meaning that the term ‘euthanasia’ has for them, as well as their attitudes toward this practice. This study explores psychological meaning and attitudes toward euthanasia in 546 Mexican subjects, either medical students or physicians, who were divided into three groups: a) (...) beginning students, b) advanced students, and c) physicians. We used the semantic networks technique, which analyzed the words the participants associated with the term ‘euthanasia’. Positive psychological meaning, as well as positive attitudes, prevailed among advanced students and physicians when defining euthanasia, whereas both positive and negative psychological meaning together with more ambivalent attitudes toward euthanasia predominated in beginning students. The findings are discussed in the context of a current debate on a bill proposing active euthanasia in Mexico City. (shrink)
Abstract The introduction of genetically modified plants into the environment has been marked by different positions, either in favor of or against their release. However, the problem goes well beyond such contradictory positions; it is necessary to take into account the legislation, ethics, biosafety, and the environment in the considerations related to the release of genetically modified organisms (GMOs). To this end, the Brazilian Committee of Biosafety (CTNBio), a consultative and deliberative multidisciplinary collegiate, provides technical and advisory support to the (...) Brazilian Federal Government. This committee consists of scientists and non-scientists who participate in evaluating the dossiers of companies that are requesting approval by the Brazilian Government; consequently, the aim of this study was to investigate whether commercial approvals of GMOs were associated with the profile of the CTNBio members. Research was based on the minutes taken at CTNBio meetings carried out from 2006 up to 2009, considering law 11.105/2005 and the Constitution of 1988 as legal frameworks, to determine the number of voters in favor of or against releasing genetically modified Bt-maize, Bt-cotton, and herbicide resistant soybeans to be used in Brazilian agriculture. Via the internet, we had access to the curriculum vitae of the CTNBio members through the Plataforma Lattes database of the National Council for Scientific and Technological Development (CNPq), where we found their area of expertise. CTNBio members were divided into expert-for, expert-against, non-expert-for, and non-expert-against. Results showed that CTNBio decisions could be based on technical criteria as well as on the policy of the institution that expert-members were representing.

This paper represents the attempt to define a methodology that can evaluate the degree to which companies'' information systems correspond to needs determined by the objectives of sustainability the firm imposes on itself. The result is the creation of a general model which define the correct approach to evaluating information systems – a model which should be adapted to the specificity of each single company which intends to adopt it. In the chart indicated, we obviously have not considered activities connected (...) to the implementation of the survey system, which are particular to each company''s situation. The first part of the paper consists of an overall introduction to the approach that has been used to assess the (MIS) of Granarolo, one of the Italian companies involved. The case study contains a profile of the company, the analysis of its MIS referred to the three dimensions of sustainability, and an evaluation of the strong points and issues to be developed. This approach to evaluate the gap between desired requirements of an information system for sustainability and current data available in a firm, has proved its consistency and usefulness. It helps to understand where data are, which dimensions, spheres, stakeholders account for and what is the level of integration between different information systems existing in the firm. (shrink)

People reject ‘paradoxical’ inferences, such as: Luisa didn't play music; therefore, if Luisa played soccer, then she didn't play music. For some theorists, they are invalid for everyday conditionals, but valid in logic. The theory of mental models implies that they are valid, but unacceptable because the conclusion refers to a possibility inconsistent with the premise. Hence, individuals should accept them if the conclusions refer only to possibilities consistent with the premises: Luisa didn't play soccer; therefore, if (...)Luisa played a game then she didn't play soccer. Two experiments corroborated this prediction for three sorts of ‘paradox’, including a disjunctive paradox. (shrink)
The article investigates how the problem of (linguistic) reference is treated in Gilbert of Poitiers' Commentaries on Boethius' Opuscula sacra . In this text the terms supponere, suppositus,-a,-um , and suppositio mainly concern the act of a speaker (or of the author of a written text) that consists of referring—by choosing a name as subject term in a proposition—to one or more subsistent things as what the speech act (or the written text) is about. Supposition is for Gilbert an action (...) performed by a speaker, not a property of terms, and his `contextual approach' has a pragmatic touch: “we do not predicate in order to supposit as much as we supposit in order to predicate“. Language is considered by Gilbert as a system for communication between human beings, key notions are the `sense in the author's mind' ( sensus mentis eius qui loquitur ) and the `interpreter's understanding' ( intelligentia lectoris ). The phenomenon of `disciplinal' discourse (“man is a species of individuals“) is treated by means of these hermeneutic notions and not by means of a special kind of supposition. (shrink)
Much current research is devoted to children’s non-adult responses to sentences containing the universal quantifier every. In this chapter we review two alternative views: one that attributes children’s responses to nonadult grammars and one that focuses on extra-linguistic factors to explain children’s non-adult responses. We argue that the grammatical view faces several theoretical concerns, and, in light of research experimental findings, we demonstrate that it also suffers from limited explanatory power.

Studies of adult sentence processing have established that the referential context in which sentences are presented plays an immediate role in their interpretation, such that referential features of the context mitigate, and even eliminate, so-called ‘garden-path’ effects. Perceivers experience garden path effects almost exclusively when they are attempting to parse locally ambiguous linguistic structures in the absence of context, or in infelicitous contexts. The finding that the referential context ordinarily obviates garden path effects is compelling evidence for the Referential Theory (...) of parsing, advanced originally by Crain and Steedman, (1985) and extended in Altmann and Steedman (1988).

We introduce new proof systems for propositional logic, simple deduction Frege systems, general deduction Frege systems, and nested deduction Frege systems, which augment Frege systems with variants of the deduction rule. We give upper bounds on the lengths of proofs in Frege proof systems compared to lengths in these new systems. As applications we give near-linear simulations of the propositional Gentzen sequent calculus and the natural deduction calculus by Frege proofs. The length of a proof is the number of lines (...) (or formulas) in the proof. A general deduction Frege proof system provides at most quadratic speedup over Frege proof systems. A nested deduction Frege proof system provides at most a nearly linear speedup over Frege system where by "nearly linear" is meant the ratio of proof lengths is O(α(n)) where α is the inverse Ackermann function. A nested deduction Frege system can linearly simulate the propositional sequent calculus, the tree-like general deduction Frege calculus, and the natural deduction calculus. Hence a Frege proof system can simulate all those proof systems with proof lengths bounded by O(n · α(n)). Also we show that a Frege proof of n lines can be transformed into a tree-like Frege proof of O(n log n) lines and of height O(log n). As a corollary of this fact we can prove that natural deduction and sequent calculus tree-like systems simulate Frege systems with proof lengths bounded by O(n log n). (shrink)
This article is a review of Paul Dumouchel's Emotions which focuses on the two levels of his emotion theory and heuristic. It interprets them both as the expression, in the domain of emotions, of a post-classical conception of nature and science that belongs to the tradition of scientific research on self-organization. Its main thesis, which is also shared by Emotions , is that creativity in nature and science corresponds to a process of coordination.
In case of special engineering projects of important relevance it is interesting to pay attention to several possible risks; some of them are in the field of morality or ethics. Due to the social importance of these risks, additional considerations or even additional warranties are justified.

Elective abortion has become an issue of ethical and political debate in many countries including Mexico. As gynecologists are directly involved in the practice of abortion, it is important to know the psychological meaning that the term ‘elective abortion’ has for them. This study explores the psychological meaning and attitudes toward elective abortion of one hundred and twenty-three Mexican gynecologists. We used the semantic networks technique, which analyzed the words the participants associated with the term ‘elective abortion’. The defining words (...) most frequently used by participants implied a negative sanction. There were important differences by gender and religiosity: male gynecologists, as well as those with strong religious beliefs (mainly Catholics), revealed a more negative psychological meaning and more negative attitudes than females or physicians with weak religious beliefs. A contribution of the present study is that it highlights the importance of psychology to enhancing understanding of the issue of elective abortion. (shrink)
