Extending Context-Sensitivity in Term Rewriting

We propose a generalized version of context-sensitivity in term rewriting based on the notion of "forbidden patterns". The basic idea is that a rewrite step should be forbidden if the redex to be contracted has a certain shape and appears in a certain context. This shape and context is expressed through forbidden patterns. In particular we analyze the relationships among this novel approach and the commonly used notion of context-sensitivity in term rewriting, as well as the feasibility of rewriting with forbidden patterns from a computational point of view. The latter feasibility is characterized by demanding that restricting a rewrite relation yields an improved termination behaviour while still being powerful enough to compute meaningful results. Sufficient criteria for both kinds of properties in certain classes of rewrite systems with forbidden patterns are presented

A sex difference in the context-sensitivity of dominance perceptions

Although dominance perceptions are thought to be important for effective social interaction, their primary function is unclear. One possibility is that they simply function to identify individuals who are capable of inflicting substantial physical harm, so that the perceiver can respond to them in ways that maximize their own physical safety. Another possibility is that they are more specialized, functioning primarily to facilitate effective direct (i.e., violent) intrasexual competition for mates, particularly among men. Here we used a priming paradigm to investigate these two possibilities. Facial cues of dominance were more salient to women after they had been primed with images of angry men, a manipulation known to activate particularly strong self-protection motivations, than after they had been primed with images of angry women or smiling individuals of either sex. By contrast, dominance cues were more salient to men after they had been primed with images of women than when they had been primed with images of men (regardless of the emotional expressions displayed), a manipulation previously shown to alter men's impressions of the sex ratio of the local population. Thus, men's dominance perceptions appear to be specialized for effective direct competition for mates, while women's dominance perceptions may function to maximize their physical safety more generally. Together, our results suggest that men's and women's dominance perceptions show different patterns of context-sensitivity and, potentially, shed new light on the routes through which violence and intrasexual competition have shaped dominance perceptions

Hearing meanings: the revenge of context

According to the perceptual view of language comprehension, listeners typically recover high-level linguistic properties such as utterance meaning without inferential work. The perceptual view is subject to the Objection from Context: since utterance meaning is massively context-sensitive, and context-sensitivity requires cognitive inference, the perceptual view is false. In recent work, Berit Brogaard provides a challenging reply to this objection. She argues that in language comprehension context-sensitivity is typically exercised not through inferences, but rather through top-down perceptual modulations or perceptual learning. This paper provides a complete formulation of the Objection from Context and evaluates Brogaards reply to it. Drawing on conceptual considerations and empirical examples, we argue that the exercise of context-sensitivity in language comprehension does, in fact, typically involve inference

Copredication, polysemy and context-sensitivity

Copredication, as exhibited by sentences such as ‘That book is heavy but informative,’ is commonly seen as a phenomenon that is tied to sentences featuring polysemous expressions. David Liebesman and Ofra Magidor have recently attacked this view by arguing that ‘book’ has a single context-sensitive sense. The first aim of the present paper is to show that Liebesman and Magidor are wrong to claim that ‘book’ is univocal, but that they may nonetheless be right to question that copredication requires polysemy. Its second aim is to consider implications of this result for the debates on copredication and on semantic variability.Peer Reviewe

A Purpose for Context Sensitivity

This thesis has two parts. In Part I there is an argument for the conclusion that a linguistic phenomenon known as (radical) context-sensitivity is to be expected given the limitations of those who use language to reason about empirical states of affairs. The phenomenon arises as a consequence of a process that must be performed to use language to reason validly. In Part II it is explained why the phenomenon, understood in light of the discussion of Part I, does not threaten the possibility of communication. Some potential readers might be interested to know that in Part I there's a fair amount of exegesis of arguments for the existence of (radical) context-sensitivity put forward by Charles Travis. Some potential readers might be interested to know that in Part II use is made of work by Erving Goffman and some conversation analysts

Grip Force Reveals the Context Sensitivity of Language-Induced Motor Activity during “Action Words

Studies demonstrating the involvement of motor brain structures in language processing typically focus on \ud time windows beyond the latencies of lexical-semantic access. Consequently, such studies remain inconclusive regarding whether motor brain structures are recruited directly in language processing or through post-linguistic conceptual imagery. In the present study, we introduce a grip-force sensor that allows online measurements of language-induced motor activity during sentence listening. We use this tool to investigate whether language-induced motor activity remains constant or is modulated in negative, as opposed to affirmative, linguistic contexts. Our findings demonstrate that this simple experimental paradigm can be used to study the online crosstalk between language and the motor systems in an ecological and economical manner. Our data further confirm that the motor brain structures that can be called upon during action word processing are not mandatorily involved; the crosstalk is asymmetrically\ud governed by the linguistic context and not vice versa

Semantic content and compositional context-sensitivity

Algunos teóricos han rechazado recientemente la concepción del contenido semántico de una oración como proposición mínima afirmando que para conseguir una proposición mínima a menudo se necesitan aspectos intencionales del contexto. Sin embargo, minimalistas como Borg siguen defendiendo que las oraciones en un contexto estrecho expresan proposiciones mínimas sin tener en cuenta las intenciones y lo defienden resolviendo o disolviendo las objeciones de incompletitud. En este artículo mostramos que esas supuestas defensas del proposicionalismo no sirven para evitar otras objeciones genuinas que dependen de la sensibilidad contextual composicional. Nuestro objetivo es mostrar que hay expresiones complejas que demandan composicionalmente de modo obligatorio efectos pragmáticos cuya recuperación depende de las intenciones y, por ello, proporcionan evidencia contra el tipo de proposicionalismo que fundamenta la defensa del minimismo semántico; A variety of theorists have recently argued against the explanation of the semantic content of a sentence as a minimal proposition claiming that intentional aspects of the context are often needed to obtain a minimal proposition. Minimalists such as Borg, however, still defend intention-insensitive minimal propositions for sentences in a narrow context and provide solutions or dissolutions against incompleteness objections. In this paper, we show that these putative defences of propositionalism do not serve to avoid some additional genuine objections which arise from compositional context-sensitivity. We aim to show that there are complex expressions which compositionally demand intention-sensitive pragmatic effects in a mandatory way and, for that reason, they provide us with evidence against the type of propositionalism that substantiates the defence of semantic minimalis

Context sensitivity by development INGOs in Myanmar

This chapter presents analysis of new primary research data collected on INGOs working inside Myanmar. In particular, it looks at the contextualisation they make to common international development approaches, in order to attain greatest effectiveness in this specific context. This research is based on in-depth interviews of forty-seven key informants from INGOs, UN organisations and local NGOs, working within Myanmar. The key finding is that INGO\u27s believe that, with appropriate contextualisation, their effectiveness is not as heavily restricted in Myanmar as is commonly perceived, particularly in addressing the worst impact of extreme poverty in communities, but also in areas such as advocacy and capacity development of the emerging civil society
