Item A cognitive approach to analyzing demonstratives in Tunisian Arabic.(2009-11) Khalfaoui, AmelDemonstratives have traditionally been analyzed as `pointing words' whose primary function is to indicate relative spatial or temporal distance of a referent from speech participants. Recent research argues that the meaning of demonstratives is not limited to spatial distance and has given alternative accounts for the use of demonstratives that focus on other cognitive and pragmatic meanings (e.g., Gundel, Hedberg and Zacharski 1993, Enfield 2003, Botley and McEnery 2001, OH 2001). This dissertation contributes to research that looks at alternative meanings for demonstratives, focusing on Tunisian Arabic (TA). The goal of the dissertation is two-fold. First, working within the Givenness Hierarchy framework (Gundel et al.), it aims to show how TA demonstratives are used to indicate cognitive status, the assumed memory and attention status of a referent in the mind of the addressee. A combined methodology of questionnaires and corpus analysis is used to test hypotheses formed in a previous study (Khalfaoui: 2004) about proposed correlations between cognitive status and single demonstrative forms in TA and extend the analysis to phrases with double demonstratives. The second goal of this dissertation is to show how other factors can further restrict the choice among certain demonstrative forms that encode the same cognitive status. Specifically, it is shown that when there is more than one activated referent, communicators choose the demonstrative haða as a determiner, but not as a pronoun, although both the determiner and the pronoun encode the same cognitive status. I argue that Relevance Theory (Sperber and Wilson 1986/1995) provides a cognitive explanation for why communicators avoid the demonstrative pronoun in such case. This dissertation also discusses the advantages and limitations of the questionnaire and the corpus analysis as research tools.Item Control and disposal of demonstratives, with electrophysiological evidence from English and Japanese(2014-06) Stevens, James MichaelDemonstratives are lexical forms that pick out an object by making use of constraints in a discourse context to establish some form of contrast. They represent among the most basic uses of language, yet escape simple definition. The two forms gthish and gthath in English, the three forms ,± gko,h ,» gso,h , gah in Japanese, etc. have traditionally been interpreted in terms of relative distance from the speaker or hearer to the object. An alternative framework presents demonstratives as a device to refocus attention (e.g., Strauss, 2002), where gthish requires more of the hearerfs attention, to represent new information, or to refer to objects relatively important in the discourse, versus objects called gthath or gith. However, distance or attention alone is an insufficient parameter to predict form selection. This dissertation builds upon Brovold and Grushfs (2012) analysis of demonstratives in terms of control over an object. I propose that demonstrative forms, at least in English and Japanese, can be predicted from an array of control spaces that allow for varying levels of potential action toward an object. The proposed framework of control spaces implies an embodied view of language, such that language and physical behavior work toward shared goals and link mature human language use to other forms of animal communication, to child language acquisition, and with adult humansf response to a changing environment (De Ruiter, 2006; Melinger & Levelt, 2005).The control space framework incorporates previous models and makes three specific predictions. First, relative distance serves as one determinant for demonstrative form selection. Second, the weight of relative distance in demonstrative form selection will decrease without shared eye gaze between the speaker and hearer. 3. Demonstrative use would show as a tendency greater dependency on the co-speech pointing gesture for speakers of a language (e.g., English) that has fewer demonstrative terms than another (e.g., Japanese). To evaluate the three predictions, two perceptual studies that employed behavioral and event-related potential (ERP) measures were conducted to assess language usersf intuitions and cortical-level neural responses to the presentation of demonstrative expressions in differing visual contexts. When the simultaneous visual context with demonstrative expressions did not correspond with expected relative distances among speaker, hearer, and object, participants responded with significantly longer reaction times accompanied by a brain response called the N400, which is associated with semantic/contextual incongruities (Kutas & Hillyard, 1980, 1984). The elicitation of the N400 response for the incongruent audiovisual matchup in demonstrative use depended on shared gaze between the speaker and hearer, and the N400 responses were found in both English and Japanese subjects. English and Japanese subjects, however, differed in their responses to trials that did not include a pointing gesture in the visual scenes. In the absence of co-speech pointing gesture, English speakers expressed a P600 response, an index of pattern violations, but Japanese speakers did not. These findings indicate that in addition to spatial distance, language users rely on shared gaze in determining the proper use of demonstrative forms and show language-specific sensitivity to the presence or absence of gesture when analyzing demonstratives.The results of this dissertation project highlight the contingent, contrastive, and attention-orienting nature of demonstratives and further illustrate the necessity to study speech communication as a multimodal social event, which is subject to a number of factors, including perspectives of the speaker and listener, physical context, gesture, and language per se. Demonstratives function as basic lexical means to make meaning out of the world. They represent a special case of names, which are interpreted here as deictic means to form an object out of a nameless ground. Demonstratives, more specifically, serve as names that are used once and then no longer refer to the same object, resuming the naming practice with every use. The ERP results reported in this dissertation show promising brain signature markers for understanding the multimodal processing nature of spatial demonstratives. Further directions for research are suggested, including measuring the relationship between autistic individualsf competence with demonstratives alongside their imitative physical skills.
