Preparing words in speech production is normally a fast and accurate process. We generate them two or three per second in fluent conversation; and overtly naming a clear picture of an object can easily be initiated within 600 msec after picture onset. The underlying process, however, is exceedingly complex. The theory reviewed in this target article analyzes this process as staged and feedforward. After a first stage of conceptual preparation, word generation proceeds through lexical selection, morphological and phonological encoding, phonetic (...) encoding, and articulation itself. In addition, the speaker exerts some degree of output control, by monitoring of self-produced internal and overt speech. The core of the theory, ranging from lexical selection to the initiation of phonetic encoding, is captured in a computational model, called WEAVER++. Both the theory and the computational model have been developed in interaction with reaction time experiments, particularly in picture naming or related word production paradigms, with the aim of accounting for the real-time processing in normal word production. A comprehensive review of theory, model, and experiments is presented. The model can handle some of the main observations in the domain of speech errors (the major empirical domain for most other theories of lexical access), and the theory opens new ways of approaching the cerebral organization of speech production by way of high-temporal-resolution imaging.

If language change is constrained by grammatical structure, then synchronic assumptions have diachronic consequences. Theories of grammar can then in principle contribute to explaining properties of change, or conversely be falsified by historical evidence. This has been the main stimulus for incorporating historical linguistics into generative theorizing.

I address the problem of the distinction between semantic and conceptual representations from general considerations about how to distinguish a representational kind. I consider three different ways of telling representational kinds apart – in terms of structure, processing and content – and I examine if semantic representations may constitute a distinct kind with respect to each of them. I argue that the best options for semantic representation to be regarded as a distinct representational kind with respect to each of the (...) three criteria conflict with each other, since it appears respectively as an atomic representation, as a sort of procedural rule or as a structured complex.

The main goal of this paper is to show that there are many phenomena that pertain to the construction of truth-conditional compounds that follow characteristic patterns, and whose explanation requires appealing to knowledge structures organized in specific ways. We review a number of phenomena, ranging from non-homogenous modification and privative modification to polysemy and co-predication that indicate that knowledge structures do play a role in obtaining truth-conditions. After that, we show that several extant accounts that invoke rich lexical meanings to (...) explain such phenomena face problems related to inflexibility and lack of predictive power. We review different ways in which one might react to such problems as regards lexical meanings: go richer, go moderately richer, go thinner, and go moderately thinner. On the face of it, it looks like moderate positions are unstable, given the apparent lack of a clear cutoff point between the semantic and the conceptual, but also that a very thin view and a very rich view may turn out to be indistinguishable in the long run. As far as we can see, the most pressing open questions concern this last issue: can there be a principled semantic/world knowledge distinction? Where could it be drawn: at some upper level (e.g. enriched qualia structures) or at some basic level (e.g. constraints)? How do parsimony considerations affect these two different approaches? A thin meanings approach postulates intermediate representations whose role is not clear in the interpretive process, while a rich meanings approach to lexical meaning seems to duplicate representations: the same representations that are stored in the lexicon would form part of conceptual representations. Both types of parsimony problems would be solved by assuming a direct relation between word forms and (parts of) conceptual or world knowledge, leading to a view that has been attributed to Chomsky (e.g. by Katz 1980) in which there is just syntax and encyclopedic knowledge.

For many years, it has been common-ground in semantics and in philosophy of language that semantics is in the business of providing a full explanation about how propositional meanings are obtained. This orthodox picture seems to be in trouble these days, as an increasing number of authors now hold that semantics does not deal with thought-contents. Some of these authors have embraced a “thin meanings” view, according to which lexical meanings are too schematic to enter propositional contents. I will suggest (...) that it is plausible to adopt thin semantics for a class of words. However, I’ll also hold that some classes of words, like kind terms, plausibly have richer lexical meanings, and so that an adequate theory of word meaning may have to combine thin and rich semantics.

There is an ongoing debate about the meaning of lexical words, i.e., words that contribute with content to the meaning of sentences. This debate has coincided with a renewal in the study of polysemy, which has taken place in the psycholinguistics camp mainly. There is already a fruitful interbreeding between two lines of research: the theoretical study of lexical word meaning, on the one hand, and the models of polysemy psycholinguists present, on the other. In this paper I aim at (...) deepening on this ongoing interbreeding, examine what is said about polysemy, particularly in the psycholinguistics literature, and then show how what we seem to know about the representation and storage of polysemous senses affects the models that we have about lexical word meaning.

There are a number of well-known restrictions for the Dative Alternation (cf. Green (1974), Oehrle (1976), Gropen, Pinker, Hollander, & Goldberg (1989), Pinker (1989), Pesetsky (1992), Levin (1993). I will show that several of the low-level semantic restrictions are consequences of a more general one involving the incorporation of a manner component into the meaning of the verb. These restrictions can be explained by assuming two distinct representations of verbs participating in the Dative Alternation: The PO frame expresses movement of (...) an object t o a g o a l , the DO frame implies a change of possession. I will argue that these restrictions cannot be expressed in a syntactic representation of lexical meaning as in Pinker (1989) and Hale & Keyser (1993). (shrink)

The fundamental fact that any theory of case must address is that morphological form and syntactic function do not stand in a one-to-one correspondence, yet are systematically related.1 Theories of case differ in whether they define case categories at a single structural level of representation, or at two or more levels of representation. For theories of the first type, the mismatches raise a dilemma when morphological form and syntactic function diverge. Which one should the classification be based on? Generally, such (...) single-level approaches determine the case inventory on the basis of morphology using paradigmatic contrast as the basic criterion, and propose rules or constraints that map the resulting cases to grammatical relations.

Word meaning confronts us, as acutely as anything in syntax, with what Chomsky has called Plato’s problem.1 We know far more about the meaning of almost any word than we could have learned just from our exposure to uses of it. Communication would be unbearably laborious if we did not share with other speakers the ability to generalize the meanings of words in the right ways. As Fodor (1981) notes in arguing for the innateness of lexical semantics, the most we (...) might plausibly have learned about meaning of the verb paint is that it means something like “to cover with paint”. Even if we have only seen this done with a brush, we have no hesitation in applying the verb correctly to novel techniques of painting, such as rolling, spraying, or dipping. But when a vat of paint explodes in a paint factory, covering everyone with paint, or when Vel´. (shrink)

The purpose of this paper is to propose a framework of lexical meaning, broadly along the lines of Cognitive Semantics (Langacker 1987a). Within the proposed model, all aspects of meaning are to be explained in terms of properties of ontologies in conceptual space, i.e. properties of content ontologies and schematic ontologies and construals which are imposed on the conceptual structures on the occasion of use. It is through the operations of construals on ontological structures that different readings of lexical expressions (...) arise. Lexical meanings are dynamic and sensitive to contextual demands, rather than fixed and stable. In a dynamic, usage-based model like this, polysemy and multiple readings emerge as a natural consequence of the human ability to think flexibly. Another more specific purpose of this paper is to draw attention to the usefulness of ontologies in linguistic research in general and semantic modelling in particular. (shrink)

This volume is dedicated to Prof. Dag Prawitz and his outstanding contributions to philosophical and mathematical logic. Prawitz's eminent contributions to structural proof theory, or general proof theory, as he calls it, and inference-based meaning theories have been extremely influential in the development of modern proof theory and anti-realistic semantics. In particular, Prawitz is the main author on natural deduction in addition to Gerhard Gentzen, who defined natural deduction in his PhD thesis published in 1934. The book opens with an (...) introductory paper that surveys Prawitz's numerous contributions to proof theory and proof-theoretic semantics and puts his work into a somewhat broader perspective, both historically and systematically. Chapters include either in-depth studies of certain aspects of Dag Prawitz's work or address open research problems that are concerned with core issues in structural proof theory and range from philosophical essays to papers of a mathematical nature. Investigations into the necessity of thought and the theory of grounds and computational justifications as well as an examination of Prawitz's conception of the validity of inferences in the light of three “dogmas of proof-theoretic semantics” are included. More formal papers deal with the constructive behaviour of fragments of classical logic and fragments of the modal logic S4 among other topics. In addition, there are chapters about inversion principles, normalization of proofs, and the notion of proof-theoretic harmony and other areas of a more mathematical persuasion. Dag Prawitz also writes a chapter in which he explains his current views on the epistemic dimension of proofs and addresses the question why some inferences succeed in conferring evidence on their conclusions when applied to premises for which one already possesses evidence.

The concept of “necessity of thought” plays a central role in Dag Prawitz’s essay “Logical Consequence from a Constructivist Point of View” (Prawitz 2005). The theme is later developed in various articles devoted to the notion of valid inference (Prawitz, 2009, forthcoming a, forthcoming b). In section 1 I explain how the notion of necessity of thought emerges from Prawitz’s analysis of logical consequence. I try to expound Prawitz’s views concerning the necessity of thought in sections 2, 3 and 4. (...) In sections 5 and 6 I discuss some problems arising with regard to Prawitz’s views. (shrink)

This paper explores how words relate to concepts. It argues that in many cases, words get their meanings in part by associating with concepts, but only in conjunction with substantial input from language. Language packages concepts in grammatically determined ways. This structures the meanings of words, and determines which sorts of concepts map to words. The results are linguistically modulated meanings, and the extralinguistic concepts associated with words are often not what intuitively would be expected. The paper concludes by discussing (...) implications of this thesis for the relation of word to sentence meaning, and for issues of linguistic determinism. (shrink)

The transition from Middle English to Modern English in the second half of the 14th century is a turning point in the syntax of the language. It is at once the point when several constraints on nominal arguments that had been gaining ground since Old English become categorical, and the point when a reorganization of the functional category Infl is initiated, whose completion over the next several centuries yields essentially the syntactic system of the present day. From this time on, (...) subjects are obligatory, and they must be placed in Spec-IP position. In the VP, the last traces of OV order disappear, the order of direct and indirect object becomes fixed, the first “recipient passives” enter the language, and objects cease to be separable from the verb by adverbs or adjuncts. The V2 constraint of Old and Middle English is lost, as topicalized constituents cease to trigger verb-fronting. Concurrently, in the Infl system, the first instances of periphrastic do-support begin to replace fronting of the finite main verb, and, with the appearance of split infinitives and pro-infinitives, to starts to pattern as a non-finite Aux rather than, as in earlier stages, as a prefix marking the infinitive. All these changes have been dated to the second half of the 14th century, most of them specifically to the period between 1360 and 1380. (shrink)

El significado de los términos numéricos es objeto de debate en la lingüística, la pragmática y la filosofía del lenguaje. En este trabajo defiendo una versión contextualista en la cual propongo que, más que consistir en un concepto específico, la semántica de los términos numéricos es una vía convencional para activar cognitivamente una zona conceptual que contiene a los conceptos numéricos que pueden expresarse a través de su uso. Las interpretaciones que un término numérico puede recibir están dadas por la (...) interacción de la forma lógica del enunciado en que aparece, la activación de una zona conceptual específica y la búsqueda de relevancia óptima. Esta propuesta explica evidencia lingüística y empírica de la que otras posturas no pueden dar cuenta. (shrink)

This paper examines the literature on meta-moral cognition and juxtaposes that with meta-cognition. At a basic level, the moral agent coordinates and assigns meaning to the various micro-concepts and moral concepts involved in a moral judgment. These concepts are combined to make moral assumptions. Meta-moral cognition is a higher level cognitive skill. The skill helps the moral agent to understand the cognitive process, control it, regulate the concepts and strategies used, and helps to reflect on the right and wrong of (...) the formulated moral judgment. To develop such moral taxonomy, the moral agent needs to understand the process of reasoning. (shrink)
