This investigation joins recent research on problems with ambiguity in two fields, argumentation and computing. In argumentation, there is a concern with fallacies arising from ambiguity, including equivocation and amphiboly. In computing, the development of agent communication languages is based on conversation policies that make it possible to have information exchanges on the internet, as well as other forms of dialogue like persuasion and negotiation, in which ambiguity is a problem. Because it is not possible to sharply differentiate between problems arising from ambiguity and those arising from vagueness, obscurity and indeterminacy, some study of the latter is included. The semantic web is based on what are called ontologies, or systems of classification of concepts, shown to be useful tools for dealing with these problems.

The idea that speaking a language is a rule‑ (or convention‑)governed form of behavior goes back at least to Wittgenstein’s language-game analogy, and can be found most prominently in the work of Searle and Alston. Both theorists have a conception of illocutionary rules as putting illocutionary conditions on utterance acts. We argue that this conception of illocutionary rules is inadequate — it does not meet intuitively plausible conditions of adequacy for the description of illocutionary acts. Nor are illocutionary rules as so conceived necessary to account for the normative dimension of illocutionary acts. In light of these conclusions we address the question of what a conception of language use not as rule-governed, but still normative, might look like.

This study investigates whether addressees visually attend to speakers’ gestures in interaction and whether attention is modulated by changes in social setting and display size. We compare a live face-to-face setting to two video conditions. In all conditions, the face dominates as a fixation target and only a minority of gestures draw fixations. The social and size parameters affect gaze mainly when combined and in the opposite direction from the predicted with fewer gestures fixated on video than live. Gestural holds and speakers’ gaze at their own gestures reliably attract addressees’ fixations in all conditions. The attraction force of holds is unaffected by changes in social and size parameters, suggesting a bottom-up response, whereas speaker-fixated gestures draw significantly less attention in both video conditions, suggesting a social effect for overt gaze-following and visual joint attention. The study provides and validates a video-based paradigm enabling further experimental but ecologically valid explorations of cross-modal information processing.

This article explores the role of affect in the disorganized language and thought that can manifest itself in bipolar disorder. Bipolar disorder, or as it was previously known, manic-depressive illness, can produce psychotic language and thought in its more extreme forms. During the production of discourse in bipolar disorder, there is a strong correlation between the underlying affective state, i.e., depression, euthymia, hypomania, and mania, and linguistic and cognitive performance. A psycholinguistic model of the dynamics between language, thought, and affect in bipolar disorder based on McNeill’s (1992, 2000) concept of a “Growth Point” is proposed. In particular, the poetic structural phases of discourse production in bipolar disorder, which vary according to the underlying affective state, provide a phenomenological bridge between the psychotic discourse of mania and normal language production.

Just how foundational metaphor is to cultural understanding has been a matter of considerable debate, manifested in the question of whether cultural models are, at bottom, based on conceptual metaphors (Gibbs 1994; Lakoff 1993; Lakoff and Johnson 1999; Quinn 1991). This paper revisits this debate by examining a new set of metaphorical expressions involving proper names, which are widespread in Singapore society. These expressions indicate that Singaporeans tend to describe local entities in terms of American ones, thus reflecting what might be called a cultural model of modernity. The paper shows that no conceptual metaphor can be plausibly said to ground this model. It then goes on to develop the other possibility: that the model is non-metaphorical and that the expressions are chosen because of their fit with the modernity model.

Sounds like h-nmm, hh-aaaah, hn-hn, unkay, nyeah, ummum, uuh, um-hm-uh-hm, um and uh-huh occur frequently in American English conversation but have thus far escaped systematic study. This article reports a study of both the forms and functions of such tokens in a corpus of American English conversations. These sounds appear not to be lexical, in that they are productively generated rather than finite in number, and in that the sound–meaning mapping is compositional rather than arbitrary. This implies that English bears within it a small specialized sub-language which follows different rules from the language as a whole. The functions supported by this sub-language complement those of main-channel English; they include low-overhead control of turn-taking, negotiation of agreement, signaling of recognition and comprehension, management of interpersonal relations such as control and affiliation, and the expression of emotion, attitude, and affect.
