This study explores how bilingualism impacts lexical selection within spontaneous spoken language production. The particular analysis focuses on the choice between synonymous verbs in English. The main hypothesis predicts that, as a result of crosslinguistic influence, bilingual speakers of French and English will opt for the English synonym which has structural correspondence to the French translation equivalent more often than monolingual speakers, who do not experience an influence from French. Structural correspondence exists in two distinct ways: in the form of cognates (e.g., applaudir/applaud vs. clap) and in terms of the number of free morphemes used to convey the same semantic information (e.g., lever/raise vs. put up). The language production data was generated by participants viewing video scenes and describing the action as it progressed. The frequency with which the different verbs were used was then compared across the different participant groups: monolingual English speakers and bilingual speakers of both French and English. The bilingual group was also subdivided based on language dominance. A range of different analyses were conducted. A framework is established for interpreting the data. Bilingualism can have one of three main effects on the speech of bilinguals relative to monolinguals: (a) an expanding effect, in which bilinguals use a wider range of lexical forms than monolinguals, (b) a limiting effect, in which bilinguals use a more limited range of lexical items than bilinguals, and (c) a modifying effect, in which the range of lexical items is basically the same between bilinguals and monolinguals but varies in terms of the frequency with which those lexical forms are used (a type of CLI labeled covert). These effects interact with certain speaker variables such as which language is the speakers dominant language. The stage(s) within the language production process at which CLI impacts ultimate lexicalization is also explored. Current models of language production which focus on lexical selection are discussed. The results of this study are most compatible with specific notions such as lexical access being target-language non-specific (see Costa, 2004, for example) and the Weaker Links Hypothesis (e.g., Gollan and Silverberg, 2001; Gollan, Montoya, & Werner, 2002).

In the McGurk Effect (McGurk & MacDonald, 1976), a visual depiction of a speaker silently mouthing the syllable [ga]/[ka] is presented concurrently with the auditory input [ba]/[pa], resulting in “fused” [da]/[ta] being heard. Deonarine (2010) found that increasing the intensity (volume) of the auditory input changes the perception of the auditory input from [ga] (at quiet volume levels) to [da], and then to [ba] (at loud volume levels). The present experiments show that reducing both ambient noise (additional frequencies in the environment) and stimulus noise (excess frequencies in the sound wave which accompany the intended auditory signal) prevents the illusory percept. This suggests that noise is crucial to audiovisual integration and that the McGurk effect depends on the existence of auditory ambiguity.

The purpose of this study is to investigate disfluency and gesture in the second language under specific conditions such as familiarity vs. non-familiarity, concrete topic type vs. abstract topic type and speaking with native speaker vs. speaker with non-native speaker. The sample of this study was sixteen students from the Department of Basic English in Middle East Technical University (DBE), three instructors from DBE and one instructor from Modern Language Department in Middle East Technical University. Two of the instructors are native and the rest of them are non-native speakers of English. With an assigned instructor each student spoke on the following topics: making spaghetti, giving directions, spring festival and clashing midterms, and effects of religion on our life. The conversations on each topic were recorded audio-visually. Then the audio-visual data was annotated in terms of linguistic and gestural elements. In order to explore the relation among disfluency, gesture and controlled variables, quantitative data analysis methods were used. Levelt&rsquo / s speech production and Krauss&rsquo / s gesture production model were used as a basic framework. Dual Coding theory and Metalinguistic Awareness Theory was used to explain intricate results of the present study. As a result of the study, it was found that in the concrete topic condition, learners speak more fluently because of time and topic effects. Similarly, in the condition of familiar addressee and native speaker, learners speak more fluently than they do when speaking with a non-familiar or a non- native speaker.

It is well-known that the meaning of a word often changes depending on the context in which the word is used. Determining the appropriate interpretation for a word occurrence requires a knowledge of the range of possible meanings for that word, and consideration of those possibilities given available contextual evidence. However, there is still much to be learned about the nature of our lexical knowledge, as well as how we make use of that knowledge in the course of language comprehension. I report on a series of three experiments that explore these issues. I begin with the question of how precise our perceptions of word meaning in context really are. In Experiment 1, I present a Magnitude Estimation study in which I obtain judgments of meaning-in-context similarity over pairs of intransitive verb occur- rences, such as The kid runs / The cat runs, or The cat runs / The lane runs. I find that participants supply a large range of very specific similarity judgments, that judgments are quite consistent across participants, and that these judgments can be at least partially predicted even by simple measures of contextual properties, such as subject noun animacy and human similarity ratings over pairs of subject nouns. However, I also find that while some participants supply a great variety of ratings, many participants supply only a few unique values during the task. This suggests that some individuals are making more fine-grained judgments than others. These differences in response granularity could stem from a variety of sources. However, the offline nature of Experiment 1 does not enable direct examination of the comprehension process, but rather focuses on its end result. In Experiment 2, I present a Speed-Accuracy Tradeoff study that explores the earliest stages of meaning-in-context resolution to better understand the dynamics of the comprehension process itself. In particular, I focus on the timecourse of meaning resolution and the question of whether verbs carry context-independent default interpretations that are activated prior to semantic integration. I find, consistent with what has previously been shown for nouns, that verbs do in fact carry such a default meaning, as can be seen in early false alarms to stimuli such as The dawn broke -- Something shattered. These default meanings appear to reflect the most frequent interpretation of the verb. While these default meanings are likely an emergent effect of repeated exposure to frequent interpretations of a verb, I hypothesize that they additionally support a shallow semantic processing strategy. Recently, a growing body of work has begun to demonstrate that our language comprehension is often less than exhaustive and less than maximally accurate -- people often vary the depth of their processing. In Experiment 3, I explore changes in depth of semantic processing by making an explicit connection to research on human decision making, particularly as regards questions of strategy selection and effort- accuracy tradeoffs. I present a semantic judgment task similar to that used in Experiment 2, but incorporating design principles common in studies on decision making, such as response-contingent financial payoffs and trial-by-trial feedback on response accuracy. I show that participants' preferences for deep and shallow semantic processing strategies are predictably influenced by factors known to affect decision making in other non-linguistic domains. In lower-risk situations, participants are more likely to accept default meanings even when they are not contextually supported, such as responding "True" to stimuli such as The dawn broke -- Something shattered, even without the presence of time pressure. In Experiment 3, I additionally show that participants can adjust not only their processing strategies but also their stimulus acceptance thresholds. Stimuli were normed for truthfulness, i.e. how strongly implied (or entailed) a probe sentence was given its context sentence. Some stimuli in the task posessed an intermediate degree of truthfulness, akin to implicature, as in The log burned -- Something was dangerous (truthfulness 4.55/7). Across 3 conditions, the threshold separating "true" from "false" stimuli was moved such that stimuli such as the example just given would be evaluated differently in different conditions. Participants rapidly learned these threshold placements via feedback, indicating that their perceptions of meaning-in-context, as expressed via the range of possible conclusions that could be drawn from the verb, could vary dynamically in response to situational constraints. This learning was additionally found to occur both faster and more accurately under increased levels of risk. This thesis makes two primary contributions to the literature. First, I present evidence that our knowledge of verb meanings is at least two-layered -- we have access to a very information-rich base of event knowledge, but we also have a more schematic level of representation that is easier to access. Second, I show that these different sources of information enable different semantic processing strategies, and that moreover the choice between these strategies is dependent upon situational characteristics. I additionally argue for the more general relevance of the decision making literature to the study of language processing, and suggest future applications of this approach for work in experimental semantics and pragmatics. / text

This thesis is an investigation of the relation between language and thought in terms of the Saussurean concept of linguistic sign. However, it is not an empirical study of the relation between language and thought and, therefore, not a study of the Whorfian problem of linguistic relativity, but rather a study of how we understand the nature of language and thought such that we think they are related in a certain way. This thesis is an investigation of the “metaphysical” picture that underlies our understanding of the relation between language and thought. In this study, we believe that how we understand the nature of language and thought is implicitly related to how we understand their relation. Therefore, we cannot really deduce the relation between language and thought from our understanding of language and thought independently of how the relation is initially understood. The whole matter is indeed about what is the larger picture within which we understand the nature of language and thought. And, we think the Saussurean concept of linguistic sign, which deals with the problem of the duality of forms and ideas, provides us with such a picture. This is primarily the reason that motivates the present study. In investigating the relation between language and thought from the Saussurean semiological perspective, we will also take into account the problem of the origin of language, which we think, represents another picture of language in that it represents an attempt to study the nature of language from a naturalistic perspective. Therefore, we want to contrast the Saussurean picture of language with this naturalistic picture of language; we want to see how the problem of the origin of language is understood from a semiological perspective. This would allow us to see how language is understood from a synchronic perspective in the Saussurean picture of language. Finally, it is hoped the present study would contribute to our understanding of how language and thought is in fact always inseparable in our conception from a Saussurean perspective, that is, in terms of our existence as speakers. / published_or_final_version / Linguistics / Master / Master of Philosophy

While the referent of a non-reflexive pronoun clearly depends on context, the nature of these contextual restrictions is controversial. The present study seeks to characterize one representation that guides pronoun resolution. In causal dependant clauses, the preferred referent of a pronoun varies systematically with the verb in the main clause (contrast Sally frightened Mary because she... with Sally feared Mary because she...), a phenomenon known as "implicit causality". A number of researchers have tried to explain and predict such biases with reference to semantic classes of verbs and linguistic structure. However, the classes and representations invoked have been partly ad hoc and fitted to the phenomenon itself. In this dissertation, evidence is presented that an independently-motivated semantic theory accounts for many known and new phenomena in implicit causality. In the first study, it is shown that verbs within syntactically-defined classes show similar implicit causality biases. In the second study, it is shown that information about the participants in an event (such as their relative social status) do not affect pronoun biases, even when they do affect event representations. In the third study, it is shown that two syntactically-defined verb classes show the same pronoun biases in eight different languages. In combination, these results suggest that implicit causality biases derive primarily from the same underlying semantic representations that determine syntactic behavior and not from general, non-linguistic event representations. / Psychology

After nearly 400 years of colonial occupation by Spain, the Philippine Islands were signed over to the United States in the 1898 Treaty of Paris along with other Spanish colonies, Guam and Puerto Rico. The American acquisition of the Philippine archipelago marked the beginning of rapid linguistic, social and political transformations that have been at the center of life in the Philippines for the last century, characterized by massive swings in national language policy, the structuration of the modern educational system, political reorganizations and increased involvement in the global economy. The rapid expansion of "education-for-all" during the American Period (1898-1946) set the foundation for the role of education in daily life and created a nation of multilinguals - contemporarily, most people speak, at the very least, functional English and Filipino (official and national languages, respectively) in conjunction with their L1 (mother tongue), of which there are an estimated 170 living varieties throughout the island array. This study focuses on the minority language of Ilocano, a branch of the Malayo-Polynesian (Austronesian) language family and is the third largest minority language spoken in the Philippines with over 9 million speakers spread throughout the islands, having a strong literary tradition and a clearly defined ethnolinguistic homeland in the northernmost region of the island of Luzon. The articles contained in this dissertation variously investigate the linguistic, social, and ideological implications of the last century of contact and colonization among speakers of Ilocano and seek to understand why (and how), in light of colonization, missionization, Americanization, and globalization, minority languages like Ilocano have remained robust. Taken together, these analyses shed light on the dynamic interplay between linguistic, social, and ideological processes as they shape contemporary language practices found among Ilocano speakers negotiating the terms of their local and national participation in a continually shifting social, political, and linguistic landscape.
