In this note we consider register-machines with symbol manipulation capabilities. They can form words over a given alphabet in their registers by appending symbols to the strings already stored. These machines are similar to Post's normal systems and the related machine-models discussed in the literature. But unlike the latter devices they are deterministic and are not allowed to read symbols from the front of the registers. Instead they can compare registers and erase them. At first glance it is surprising that (...) in general these devices are as powerful as the seemingly stronger models. Here we investigate the borderline of universality for these machines. (shrink)

In this paper I develop a theory of 'function' and function as a deontic modal word and phenomenon. Kratzer’s account of the semantics for the deontic modals is invoked and using her approach a formal schema for the semantics of 'function'-sentences is proposed. My account of function is a modalized and extended version of Cummins’ systems-type account of function. In the biological and physical sciences, on this account, function is a complex empirical deontic modal property. It is built on the (...) property of X’s doing Y well enough to enable Z, which is implicitly deontic because of the evaluative but nonetheless empirical in its biological and physical applications. This account of function resolves many of the traditional puzzles about biological and physical function, and extends naturally to include the other types of function. With a variant treatment of the semantics, this account is argued also to apply to mathematical function, where it is shown to be interestingly related to Frege’s account of function. (shrink)

In the 225 years since the United States Constitution was first drafted, no single book has addressed the key questions of what constitutions are designed to do, how they are structured, and why they matter. In From Words to Worlds, constitutional scholar Beau Breslin corrects this glaring oversight, singling out the essential functions that a modern, written constitution must incorporate in order to serve as a nation's fundamental law. Breslin lays out and explains the basic functions of a modern constitution (...) -- including creating a new citizenry, structuring the institutions of government, regulating conflict between layers and branches of government, and limiting the power of the sovereign. He also moves into the esoteric, discussing the theoretical concepts behind the fundamentals of written constitutions and examining in-depth some of the most important constitutional charters from around the world. In assaying how states put the structural ideas into practice, Breslin asks probing questions about why -- and if -- constitutions matter. His answer is a resounding yes. Solidly argued and engagingly written, this comparative study in constitutional thought demonstrates clearly the key components that a state's foundational document must address. In doing so, Breslin draws a critically important distinction between constitutional texts and constitutional practice. (shrink)

Word class-specific differences in brain evoked potentials (EP) are discussed for connotative meaning and for function versus content words. A well-controlled experiment found matching lexical decision times for function and content words, but clear EP differences (component with maximum near 550 msec) among function words, content words, and nonwords that depended on brain site. Another EP component, with a 480 msec maximum, differentiated words (either function or content) from nonwords.

Wilkins & Wakefield assign importance to motor systems but skip from anatomy to cognitive structure with little attention to behavior. Organisms, no matter how sophisticated, that do not behave in accord with what they know will fall by the evolutionary wayside. Facts about behavior can supplement the authors' theory, whose hierarchical structures can accommodate an evolutionary scenario in which a million years or more of functionally varied utterances mainly limited to single words is followed by an explosion of linguistic diversity (...) with the development in the last 50,000 years or so of syntactically organized multiple word utterances.

Functional words are of substantial interest in moral philosophy because they appear to lie at the juncture of description and evaluation. This is no doubt the reason that they have played a significant part in much recent discussion of the relation between facts and values. Yet, in spite of the many discussions in which functional words have made an appearance, their significance for an understanding of the relation between facts and values remains unclear. A thorough-going examination of the nature of (...) functional words would appear to be in order. And while such a study is beyond the scope of a single article it should nevertheless be possible to make a beginning. That, at any rate, is my objective in what follows. (shrink)

Natural language expressions fall into two categories: content and function words. While function words are essential to compositional semantics, surprisingly little has been said about their emergence. In this paper, I will show that most extant approaches to the emergence of compositional signaling fail to account for the emergence of functional vocabulary. After providing a result that explains why this is so,, I will present a model and simulation results exhibiting conditions under which such vocabulary can emerge from simple learning (...) dynamics. This model captures the intuition that function words help aid communication with a limited vocabulary in the presence of contextual variability. (shrink)

We urge caution in generalising from content words to function words, in which lexical-to-phonemic feedback might be more likely. Speech perception involves more than word recognition; feedback might be outside the narrow logic of word identification but still be present for other purposes. Finally, we raise the issue of evidence from imaging studies of auditory hallucination.

En este estudio se analiza el cambio de clase de palabras en el mapudungun a través del procedimiento de derivación, desde la perspectiva tipológica de la formación de palabra (Aikhenvald, 2007). Las palabras, en la lengua mapuche, usan ciertos procesos morfológicos y sintácticos que posibilitan el cambio de clase de palabra, ya sea por la intervención de algún sufijo derivacional, por la propiedad polisémica de los mismos, o por el cambio de posición de la palabra respecto a una palabra principal. (...) Los procesos más productivos de formación de palabras suelen ser la composición y la derivación, no obstante, por razones de extensión, este artículo solo se concentra en la derivación y en el análisis de los sufijos -tu, -küle/-le, -meke, y -nge. This study analyzes word classes changes process in Mapudungun through derivation, from the typological perspective of word class formation (Aikhenvald, 2007). Words, in the Mapuche language, use certain morphological and syntactic processes that make possible word class changes, in either of three ways: the intervention of a derivational suffix, by the polysemic property of derivational suffixes, or by changing the position of the word with respect to a principal word. While the most productive processes of word formation often are composition and derivation, due to length reasons this article will focus on the derivation process and analysis of only the suffixes -tu, -küle/-le,-meke, and -nge.

Though Bloom makes a good case that learning content-word meanings requires no task-specific apparatus, he does not seriously address problems inherent in learning the meanings of functional items. Evidence from creole languages suggests that the latter process presupposes at least some task-specific mechanisms, perhaps including a list of the limited number of semantic distinctions that can be expressed via functional items, as well as default systems that may operate in cases of impoverished input.

Many individuals with developmental language disorder (DLD) and individuals who are deaf or hard of hearing (D/HH) have social–emotional problems, such as social difficulties, and show signs of aggression, depression, and anxiety. These problems can be partly associated with their executive functions (EFs) and theory of mind (ToM). The difficulties of both groups in EF and ToM may in turn be related to self-directed speech (i.e., overt or covert speech that is directed at the self). Self-directed speech is thought to (...) allow for the construction of non-sensory representations (i.e., representations that do not coincide with direct observation). Such non-sensory representations allow individuals to overcome the limits set upon them by the senses. This ability is constrained by the development of word meaning structure (i.e., the way words are understood). We argue that the greater ability to construct non-sensory representations may result in more enhanced forms of EF and ToM. We conclude that difficulties in EF, ToM, and social–emotional functioning in those with hearing and language problems may be accounted for in terms of word meaning impairments. We propose that word meaning structure and self-directed speech should be considered in assigning EF and ToM treatments to individuals with DLD and those who are D/HH. (shrink)

How do people learn to talk about the causal and temporal relations between events, and the motivation behind why people do what they do? The narrative practice hypothesis of Hutto and Gallagher holds that children are exposed to narratives that provide training for understanding and expressing reasons for why people behave as they do. In this context, we have recently developed a model of narrative processing where a structured model of the developing situation is built up from experienced events, and (...) enriched by sentences in a narrative that describe event meanings. The main interest is to develop a proof of concept for how narrative can be used to structure, organize and describe experience. Narrative sentences describe events, and they also define temporal and causal relations between events. These relations are specified by a class of narrative function words, including “because, before, after, first, finally.” The current research develops a proof of concept that by observing how people describe social events, a developmental robotic system can begin to acquire early knowledge of how to explain the reasons for events. We collect data from naïve subjects who use narrative function words to describe simple scenes of human-robot interaction, and then employ algorithms for extracting the statistical structure of how narrative function words link events in the situation model. By using these statistical regularities, the robot can thus learn from human experience about how to properly employ in question-answering dialogues with the human, and in generating canonical narratives for new experiences. The behavior of the system is demonstrated over several behavioral interactions, and associated narrative interaction sessions, while a more formal extended evaluation and user study will be the subject of future research. Clearly this is far removed from the power of the full blown narrative practice capability, but it provides a first step in the development of an experimental infrastructure for the study of socially situated narrative practice in human-robot interaction.

Swedish lexical word accents have been repeatedly said to have a low functional load. Even so, the language has kept these tones ever since they emerged probably over a thousand years ago. This article proposes that the primary function of word accents is for listeners to be able to predict upcoming morphological structures and narrow down the lexical competition rather than being lexically distinctive. Psycho- and neurophysiological evidence for the predictive function of word accents is discussed. A novel analysis displays (...) that word accents have a facilitative role in word processing. Specifically, a correlation is revealed between how much incorrect word accents hinder listeners’ processing and how much they reduce response times when correct. Finally, a dual-route model of the predictive use of word accents with distinct neural substrates is put forth. (shrink)

Growing evidence shows that early speech processing relies on information extracted from speech production. In particular, production skills are linked to word-form processing, as more advanced producers prefer listening to pseudowords containing consonants they do not yet produce. However, it is unclear whether production affects word-form encoding and/or recognition. Distinguishing recognition from encoding makes it possible to explore whether sensorimotor information is stored in long-term phonological representations or is processed when encoding a new item, but not necessarily when retrieving a (...) stored item. In this study, we asked whether speech-related sensorimotor information is retained in long-term representations of word-forms. To this aim, we tested the effect of production on the recognition of ecologically learned, real familiar word-forms. Testing these items allowed to assess the effect of sensorimotor information in a context in which encoding did not happen during testing itself. Two groups of French-learning monolinguals participated in the study. Using the Headturn Preference Procedure, each group heard two lists, each containing 10 familiar word-forms composed of either early-learned consonants or late-learned consonants. We hypothesized differences in listening preferences as a function of word-list and/or production skills. At both 11 and 14 months, babbling skills modulated orientation times to the word-lists containing late-learned consonants. This specific effect establishes that speech production impacts familiar word-form recognition by 11 months, suggesting that sensorimotor information is retained in long-term word-form representations and accessed during word-form processing.

The Emergence of Word-Meaning in Early China makes an innovative contribution to studies of language by historicizing the Chinese notion that words have "meaning" (content independent of instances of use). Rather than presuming that the concept of word-meaning had always existed, Jane Geaney explains how and why it arose in China. To account for why a normative term (yi, "duty, morality, appropriateness") came to be used for "meanings" found in dictionaries, Geaney examines interrelated patterns of word usage threading through and (...) across a wide range of genres. These patterns show that by the first millennium, as textual production exploded—and as radically different writing forms (in Buddhist sutras) were encountered—yi already functioned as an externally accessible "model" for semantic interpretation of texts and sayings. The book has far-reaching implications. Because the idea of word-meaning is fundamental to theorizing, the book illuminates not only semantic ideas and the normativity of language in Early China, but also aspects of early Chinese philosophy and intellectual history. As the internet supplants one form of media (print), thereby reducing knowledge to vast digital databases, so too, this book explains, two thousand years ago a culture that prized oral and visual balance became an "empire of the text.".
