Signed languages employ finely articulated facial and head displays to express grammatical meanings such as mood and modality, complex propositions, information structure, assertions, content and yes/no questions, imperatives, and miratives. In this paper we examine two facial displays: an upper face display in which the eyebrows are pulled together called brow furrow, and a lower face display in which the corners of the mouth are turned down into a distinctive configuration that resembles a frown or upside-down U-shape. Our analysis employs (...) Cognitive Grammar, specifically the control cycle and its manifestation in effective control and epistemic control. Our claim is that effective and epistemic control are associated with embodied actions. Prototypical physical effective control requires effortful activity and the forceful exertion of energy and is commonly correlated with upper face activity, often called the “face of effort.” The lower face display has been shown to be associated with epistemic indetermination, uncertainty, doubt, obviousness, and skepticism. We demonstrate that the control cycle unifies the diverse grammatical functions expressed by each facial display within a language, and that they express similar functions across a wide range of signed languages.

A substantial amount of recent work in natural language generation has focused on the generation of ‘‘one-shot’’ referring expressions whose only aim is to identify a target referent. Dale and Reiter's Incremental Algorithm (IA) is often thought to be the best algorithm for maximizing the similarity to referring expressions produced by people. We test this hypothesis by eliciting referring expressions from human subjects and computing the similarity between the expressions elicited and the ones generated by algorithms. It turns out that (...) the success of the IA depends substantially on the ‘‘preference order’’ (PO) employed by the IA, particularly in complex domains. While some POs cause the IA to produce referring expressions that are very similar to expressions produced by human subjects, others cause the IA to perform worse than its main competitors; moreover, it turns out to be difficult to predict the success of a PO on the basis of existing psycholinguistic findings or frequencies in corpora. We also examine the computational complexity of the algorithms in question and argue that there are no compelling reasons for preferring the IA over some of its main competitors on these grounds. We conclude that future research on the generation of referring expressions should explore alternatives to the IA, focusing on algorithms, inspired by the Greedy Algorithm, which do not work with a fixed PO.

This article investigates the role of prosody in conversational humor in the HBO series Sex and the City in an exploratory study. Specifically, we examine how pitch and pauses are part of the prosodic bundle that can be used to mark an utterance as humoristic. We find that the use of prosodic resources participates not only in the marking but also the creation of humor. In this regard, we view pitch variation and pauses as having communicative strategies and cognitive benefits. (...) They are part of the performance of humor and participate in the characterization of the personage. The authors suggest the existence of a repertoire of prosodic devices associated to humor and to a particular discourse. (shrink)

This article suggests that studies of self-esteem using scales have reached a dead end, and suggest alternative directions. First we show how significance tests have obscured meager results. According to reviews, this huge body of research has yielded no substantial findings. Some sub-fields show consistent, but trivially small, effects; reviews of the entire field show none at all. Most important, the size of effects does not seem to be increasing. Three questions are raised: 1. Are new standards needed to determine (...) when to continue or stop a given line of research? 2. Are new approaches needed alternative to standardized scales and statistical tests? 3. Should future studies of self-esteem emphasize feeling and social components at least as much as cognitive components? Studies of self-esteem using interview techniques by George Brown and his colleagues suggest the need to move closer to actual data. An exploratory study that takes this direction a step further is described. We analyze social and cognitive/emotional elements second by second in discourse about topics relevant to self-appraisal and self-feeling. (shrink)

Disruptions in theory of mind faculties and the ability to relate to an intersubjective reality are widely thought to be crucial to schizophrenic symptomology. This paper applies a cognitive linguistic framework to analyze spontaneous perspective-taking in two corpora of stories told by people with a schizophrenia diagnosis. We elicited natural narrative language use through life story interviews and a guided storytelling task and analyzed the linguistic construal of viewpoint in these stories. For this analysis, we developed a reliable and widely (...) applicable viewpoint model that allows for the categorization and quantification of speakers’ linguistic presentation and navigation of spatiotemporal domains. We found that our participants skillfully presented, navigated and embedded different narrative viewpoints through a variety of linguistic viewpoint devices. They presented complex viewpoints of other people in both the here-and-now of the interaction and the there-and-then of a narrative, and made use of transition markers to demarcate spatiotemporal discourse domains. We found no differences in viewpoint variables when comparing their guided stories to a control group. If problems with intersubjectivity are indeed an essential part of schizophrenia, an explanation of how this group can take on and navigate complex linguistic viewpoints in natural narrative interaction is called for.

In this paper I focus on the limits of narrative by asking what kinds of things narratives do, and what kinds of texts do related things in other ways. In particular I focus on how narrative genres organise time in relation to value, drawing on functional linguistic models of temporality and evaluation. From a linguistic perspective, the various narrative genres negotiate different kinds of solidarity with listeners, and so the limits of narrative materialise various possibilities for communing in a culture, (...) alongside the potentialities for construing community through related and other genres of discourse—since in general, the limits/possibilities of our language (and attendant modalities of communication) are the limits/possibilities of our social world.

Process-reliabilist analyses of justification and knowledge face the generality problem. Recent discussion of this problem turns on certain untested empirical assumptions that this paper investigates. Three experiments are reported: two are free-naming studies that support the existence of a basic level in the previously unexplored domain of names for belief-forming processes; the third demonstrates that reliability judgments for the basic-level belief-forming process types are very strongly correlated with the corresponding justification and knowledge judgments. I argue that these results lend support (...) to process-reliabilism; I then go on to explore several different ways to make use of them in solutions to the generality problem. (shrink)

Several studies have highlighted the role of cross- linguistic influence in determining the over-use of overt subject pronouns in near- native speakers of a null- subject language as Italian. In this work we inquire on the role of other factors, such as age of onset of exposure and dominance with respect to the choice of subject anaphoric devices in two null-subject languages by bilingual speakers. In order to do so we first single out two languages, Italian and Greek, which do (...) not differ significantly as far as subject anaphoric devices are concerned and instantiate thus a suitable language combination to inquire on the role of relevant factors in bilingual speakers of these two languages, in the absence of cross- linguistic influence related effects (Study 1). In Study 2 we compare the productions in Italian of a group of natives speakers and two groups of near- native speakers: Greek- Italian bilinguals from birth and L2ers of Italian with Greek as an L1. Results reveal that age of onset of exposure to Italian is a relevant factor influencing over- use of overt pronouns: while bilinguals from birth do not differ from native speakers, L2ers over-use overt pronouns compared to both native speakers and bilinguals from birth. In order to establish whether dominance is a possible factor determining bilinguals’ choice of subject anaphoric devices, in Study 3 we compare two groups of Greek- Italian bilinguals from birth: bilinguals living in Greece (dominant in Greek) and bilinguals living in Italy (dominant in Italian). Results reveal no effect of dominance with respect to the production of overt subject pronouns. We found however an unexpected effect in the dominant language of one group: bilinguals living in Greece produce significantly more null pronouns and less lexical DPs in Greek compared to bilinguals living in Italy. We interpret this effect as stemming from the need to differentiate the two languages that these bilingual speakers have to handle in everyday life. Interestingly, this effect is found in the dominant language rather than in the non- dominant one, and does not concern overt pronouns. (shrink)

This article explores the principles of interaction that shape grammatical practices of conversational speech cross-linguistically. Seven such principles are explored, and the grammatical practices they give rise to are illustrated. The role of these principles in shaping non-linguistic behavior is also touched on.
