Complaining happens in all cultures, and offers a unique insight into the values, taboos, and communicative practices of a given society. The ways in which complaining is viewed and performed vary drastically not only cross-culturally, but across smaller communal groups and between individuals, too. This dissertation approaches complaining from a multilateral perspective to investigate how individuals in three different language groups – monolingual French speakers, monolingual English speakers, and native English speakers enrolled in upper-division university French courses – perceive and produce complaints as well as the influential role played by social context. In the perception study, the researcher explores how individuals within the examined language groups identify the presence of complaints and perceive their naturalness when presented with contextualized scenarios involving native speakers. In the production study, the researcher examines both the frequency with which individuals complain and the strategies they employ to perform a complaint in various social situations. Additionally, within the production study the researcher examines the frequency with which participants opt out from complaining and their provided rationale for doing so. This dissertation not only identifies a variety of universal linguistic and sociocultural features of complaints, it also uncovers several aspects distinctive to the individual language groups. At the core of this dissertation is the argument that to best understand complaint behavior, researchers should acknowledge the essential influence of social context on both the perception and production of complaints. Above all, future research must consider the complex and dynamic interplay that exists between cross-cultural complaint behaviors and social norms of politeness.

This study explores the development of second language (L2) fluency during a semester abroad and its relationship to the development of grammar, vocabulary, and language processing speed. It also considers the influence of individual participants' first language (L1) and pre-study abroad (SA) L2 fluency on the development of fluency during study abroad. Additionally, the study examines issues in the measurement of fluency, focusing on questions related to measuring pauses in L2 speech. Thirty-nine undergraduate students (L1 English) studying in Buenos Aires, Argentina, completed a pretest consisting of speaking tasks in English and Spanish, Spanish grammar and vocabulary tests, a picture-naming task, and a measure of sentence processing speed. Approximately three months later, near the end of their time abroad, they completed a posttest consisting of the same tasks, with the exception of the speaking tasks in English. Participants also filled out a questionnaire every other week during the semester in which they estimated the amount of time that they had spent interacting with native speakers of Spanish. Results show that participants experienced significant gains on most measures of fluency during study abroad. This finding was especially true for participants who began their time abroad with low L2 fluency. Nevertheless, students who began the semester abroad with high L2 fluency still had significantly higher fluency at the end of the semester than students who began with low L2 fluency. Looking at the relationship between L2 fluency and L2 linguistic knowledge (vocabulary and grammar scores) and language processing speed (picture-naming and sentence-matching scores), the study found a moderate relationship between pretest measures of L2 fluency and pretest measures of linguistic knowledge and processing speed. However, the results show no relationship between pre-SA linguistic knowledge and processing speed and gains in L2 fluency, and little relationship between gains in linguistic knowledge and processing speed and gains in L2 fluency. The best predictor of gains in L2 fluency was pre-SA L2 fluency. These results suggest that although there is a relationship between L2 linguistic knowledge and L2 fluency, having more advanced L2 linguistic knowledge prior to study abroad does not necessarily give students an advantage in the area of fluency development during study abroad. Regarding the measurement of fluency, the data show that learners with low and high levels of lexical-grammatical competence significantly differed from one another on all measures of rates of pauses (short and long pauses, filled and unfilled pauses, and mid-clause and end-of-clause pauses) as well as in the percent of pauses occurring in the middle of a clause. However, they did not significantly differ from one another in the percent of filled pauses. The findings suggest that measuring all of these pauses may be useful in examining L2 fluency. However, there is perhaps little or nothing to be gained from counting filled and unfilled pauses separately, as speakers' tendency to use more of one or the other appears to be more closely related to personal speaking style than to L2 ability.

Logographic character handwriting, such as Hanzi in Chinese, Kanji in Japanese, or Hanja in Korean, is notoriously challenging for foreign language learners. Fortunately, computer-assisted learning systems for handwriting are being improved to meet the instructional needs of teachers and learners in foreign language education. However, the effect of computer-assisted language learning in logographic handwriting has never been explored. To anchor the inquiry of the current study, the extensive complementarity approach was adopted, in which SLA research complements L2 instruction by studying the impact of a theory-based instructional method on the learning of an aspect of the L2. The present study explores the orthographic development at the initial stage of character learning among non-heritage, beginning-level learners of Chinese as a foreign language (CFL) by investigating the effect of Interactionist-instructed mediations on orthographic attrition and maintenance and by examining the relationships among awareness of internal formation sequencing, character recognition and production. Data was collected from 167 first-year CFL students in a Chinese program at a large research university in North America. In phase one, 63 students completed all the six-week lab writing tasks. In phase two, 125 students completed all the end-of-semester correlation tasks in their first semester of learning Chinese. The findings of the study are multifold. First, by closely examining the roles of input, output, and feedback in the Interactionist model, the results show that, to maximize orthographic retention and reduce attrition, the effect of working memory needs to be taken into consideration in the design of instruction for immediate kinesthetic skill training and for better development of orthographic awareness among CFL non-heritage beginners. Second, the effect of multimedia input enhancements along with handwriting output on reducing variations of character formation in character learning is also significant. Third, the effect of the handwriting feedback is not found to be significant when compared to its counterpart without feedback in computer-assisted handwriting instruction; however, its influence on the participants' writing motivations and learning objectives were observed and addressed in the study. Finally, the CFL non-heritage beginning learners' awareness of internal formation sequencing was found to be correlated with their performance in character recognition and reproduction. The pedagogical implications are discussed.

This dissertation centers on the under-researched construct of interactional competence, which refers to features of jointly constructed discourse. When applied to the testing of speaking skills in a second language, interactional competence refers to features of the discourse that the two students produce together; rather than the speaking ability or performance of each person individually. This dissertation describes the construct of interactional competence in a low-stakes, paired speaking test setting targeted at students in their second year of German instruction at the college level. The purpose of this study is two-fold. First, the study analyzes the conversational resources that are co-constructed in the test discourse to maintain mutual understanding, which is considered the basis for interactional competence. Second, the study examines the impact of task (jigsaw task and discussion task) and speaking ability-level combination (same and different ability) in the test-taker pair on the co-constructed test discourse and thus on the deployment of the conversational resources to maintain intersubjectivity. In that respect, this study also seeks to analyze how the identified conversational resources are involved in establishing and negotiating language ability identities that are displayed in the test discourse. Conversation analytic conventions were used to investigate the interactional resources that test takers deploy to maintain mutual understanding. The procedures of repair (self-repair in response to other-initiated repair, inter-turn delays, and misunderstandings as well as other-repair in conjunction with word search activities) that emerged from the inductive analysis of the test discourse have broadened the conceptualization of interactional competence in the context of paired speaking assessments. Frequency distributions of the interactional resources were created to provide a better understanding of the impact of task and ability-level combination on the co-constructed repair procedures. The rationale behind this analysis is the general understanding of language testers that both resources and context influence test performance. The findings from the quantitative analysis suggest that there are more similarities than differences in repair use across the jigsaw task and the discussion task. In addition, even though some trends in the co-construction of repair procedures may be attributed to the higher or lower speaking ability of the test takers, the relationship between the ability-level combination in the pair and the use of repair seems to be rather variable. Finally, to learn more about the interrelationship between test takers’ speaking ability and interactional competence, this dissertation also approached speaking ability in terms of test takers’ co-constructed language ability identities that are displayed in the test discourse. By means of single case analyses, the study provided a detailed picture of the relationship between language ability identities and the procedures of repair, both of which are co-constructed at the discourse level. The findings from the conversation analysis show that the speaker who provides the repair is usually able to position himself or herself as the more competent or proficient speaker in the test discourse.

Research has focused on how the effects of different types of feedback vary as a function of the complexity of the linguistic targets and on the learning of inflectional features. However, few studies have investigated the learning of rule-based verb constructions. Grounded in the interactionist approach and usage-based theory, this study investigated the effects of corrective feedback on the acquisition of rule-based verb constructions among English-speaking learners of Chinese. Specifically, this study examined the effects of input-providing feedback and output-prompting feedback on the learning of two verb constructions. Data were drawn from 18 learners of Chinese from second-year Chinese classes in an American university. The participants were divided into two groups and took a pretest, treatment, and two posttests. Learners also filled out a questionnaire about their perception and preference of feedback types. Contrary to previous research, results indicated that both recasts and metalinguistic clues had positive effects on learners' learning of the target constructions. Moreover, learners of different proficiency preferred different types of feedback. The study results provided a categorization of verb constructions into four classes based on the rules that govern their formations and constraints that work on the constructions and identified stages learners moved through when learning verb constructions. The researcher proposed an instructional model of rule-based verb constructions. The model will help instructors recognize the stage the learners' are in and provide insight into how to help learners move to a higher stage by providing instruction, corrective feedback, and practice activities.

The Spanish subjunctive has been the focus of much SLA research, largely because it poses difficulties for learners of Spanish whose L1 is English (e.g., Collentine, 1993; Stokes & Krashen, 1990; Terrell et al., 1987). Investigating the same feature in heritage learners of Spanish can provide more information about their linguistic development and also has the potential to inform our knowledge of the acquisition of the subjunctive in traditional FL learners. The present study investigates whether heritage learners recognize grammatical and ungrammatical modal choice in volitional constructions. These constructions have been selected because this use of the subjunctive does not vary by a speaker's dialect or by belief about the idea being expressed. Furthermore, given that theories of language attrition posit that the structures that are acquired earliest are the last to be lost (e.g., De Bot & Weltens, 1991) and that Spanish monolingual children acquire the subjunctive in volitional constructions first (Blake, 1980; 1983), heritage learners who have experienced some language attrition may still have knowledge of this feature. To investigate the effect that language attrition or incomplete acquisition may have on this knowledge, I also compared the SHL learners in the sample who were early bilinguals in English (those born in the United States or who immigrated before age 6) with those who were late bilingual (those who immigrated between ages 6 and 13). Students enrolled in Spanish for Heritage Learners (SHL) and Spanish as a Foreign Language (SFL) courses at three universities in the Northeast completed grammaticality judgment (GJ) and editing tasks, which contained examples of correct and incorrect mood choices, as well as distracter items. The GJ task also required participants to explain their judgments. The results indicate that SHL learners outperform their SFL peers on recognizing correct mood selection. No significant differences were found between early and late bilinguals. SHL and SFL learners tended to correct utterances that they had rejected of judged neutrally but gave different types of reasons for accepting utterances. There were several similarities between early and late bilinguals in terms of their reasons for their judgments of utterances.

This dissertation investigates second language (L2) development in the domains of morphosyntax and semantics. Specifically, it examines the acquisition of definiteness and specificity in Russian within the Feature Re-assembly framework (Lardiere, 2009), according to which the hardest L2 learning task is not to reset parameters but to reconfigure, or remap features from the way they are assembled in the L1 into new formal configurations in the L2. Within the Feature Re-assembly approach, it has been argued that re-assembling features that are represented overtly in the L1 and mapping them onto those that are encoded covertly by context in the L2 will present a greater difficulty than re-assembling features in the opposite direction (Slabakova, 2009). This dissertation examines the acquisition of four linguistic properties (types of modifiers, word order, indefinite determiners and case marking) that encode definiteness and specificity overtly or covertly in L2 Russian by English and Korean speakers. The native languages of the learners were chosen specifically in order to test various overt-covert mappings. The data obtained from two experimental tasks (grammaticality and felicity judgments) completed by 56 Russian native speaker controls, 51 English- and 53 Korean-speaking learners support Slabakova's prediction that overt-to-covert realization of the feature is more challenging than covert-to-overt realization. In addition, the findings uncovered other important factors facilitating or impeding acquisition, such as the nature of the form-to-meaning mapping (one-to-one or one-to-many) and the availability of clear, unambiguous evidence for a certain mapping in the input available to learners. Results also reveal that the presence or absence of the L1 transfer depends on the overt/covert status of the feature in the L2. That is, when the feature is marked overtly in both the L1 and L2, L1 transfer has facilitative effect on the acquisition of the feature. On the contrary, when the feature is marked covertly in both the L1 and L2, L1 transfer has no or negative effects. These findings provide new insights into the effects of the native language on L2 learnability and enable us to come to a more precise and fine-grained understanding of grammatical meaning acquisition in the second language.

This dissertation consists of two studies, which respectively investigate L2 Chinese learners' acquisition of simple wh-questions of different grammatical functions longitudinally over their first-year learning and their acquisition of indirect questions and wh-questions in complements at the end of their first year. The participants consisted of 21 first-year English-speaking learners of Chinese. Both grammaticality judgment (GJ) and oral production (OP) tests were used. Study 1 reports that only attributive wh-questions posed more difficulty to the participants than object wh-questions in OP test at the beginning stage, and adverbial wh-questions and object wh-questions were not found to be significantly different to the participants as reported in some L1 and L2 studies. This author attributed this to the different syntactic mechanism that L2 learners of movement language and learners of in-situ language go through. The initial stage of participants' grammar did not display a clear presence of [+wh] feature strength, and the development of the [-wh] feature strength in learners' L2 grammar was not linear, but U-shaped. Study 2 reveals that learners' performance on indirect questions and wh-questions in object complements was not as good as their performance on simple wh-questions at the end of first year learning. For indirect questions, the initial stage of participants' L2 grammar showed an obvious L1 influence, the embedded [+wh]. For wh-questions in complements, it did not show an L1 influence, the matrix [+wh], but an embedded [+wh], which is non-target like but resembles wide-scope wh-questions with an embedded [+wh] in Malay and Madurese. Learners' performance on simple wh-questions patterned together with that in matrix clauses of wh-questions in complements, which was better than their performance on embedded clauses of the two types of complex wh-questions. Evidence for connection between their performance on simple wh-questions and matrix clauses of wh-questions in complements regarding the grammatical feature that wh-words are not allowed in clause initial position was revealed, but there was no strong evidence for connection between their performance on embedded clauses of the two types of complex wh-questions. It suggests that learners might be using different strategies for acquisition of structures of different natures.

Having acquired some degree of oral proficiency but low (or non-existent) literacy, the learning of Chinese heritage learners' (CHLs) learning needs are different from those of Chinese foreign language learners (CFLs), who have learned Chinese only in the classroom setting. Although researchers have advocated for a separate curriculum for CHLs, creating a heritage track may not be an option for many Chinese programs due to insufficient enrollment and limited resources. Huge proficiency variations among CHLs also make it difficult to provide a language curriculum that fits the needs of all learners. Therefore, CHLs are assigned to classes with CFLs in most Chinese language programs. From a pedagogical point of view, uneven proficiency levels are a great concern for instructors who teach a language class with students of different language backgrounds and with varying abilities, especially when assigning students to work in pairs or small groups. Although CHL-CFL paired interaction has become a common phenomenon in Chinese language classes, it has not been fully explored. Grounded in sociocultural theory, this research explores the nature of dyadic interaction between Chinese heritage learners (CHLs) and Chinese foreign language learners (CFLs) in a classroom setting. It investigates the roles that Chinese heritage learners and their foreign language peers play in paired discussions, how learners' proficiency gaps influence the dynamics of paired interaction, and whether peer-peer collaboration affects learners' individual oral performance. In this study, data were collected in three intermediate-level Chinese classes. Participants first filled out a language background survey to lead to a better understanding of the environments in which they use Chinese. Next, they took two proficiency tests to assess their comprehensive Chinese skills. Over the course of a semester, ten CHL-CFL pairs engaged in paired discussions on six different occasions. Before and after each pair work session, each participant was required to give an individual verbal report assessing the influence of paired interaction on his or her oral performance. After data from the six sessions were collected, participants took an end-of-study survey, which provides their perceptions about paired discussion and their roles in paired interaction over the research period. According to the findings, three interaction patterns (passive collaboration pattern, active collaboration pattern, and peer-tutoring pattern) were identified. The results of this study show that CHLs' language background and the amount of Chinese language exposure determined the CHL-CFL proficiency gaps in each pair, and further influenced the pattern of paired interaction. Learners generated more LREs (Language-related episodes) and were more likely to acquire knowledge from pair work when the degree of interaction mutuality was high. Even when the proficiency gaps were large, the less proficient learners still could transfer new knowledge to their independent work. To conclude, this study may be of importance in presenting the dynamics of CHL-CFL paired interaction in a mixed Chinese language class, as well as in providing instructors with a better understanding of how different factors such as interlocutors' proficiency gaps, individual participants' beliefs and attitudes relate to their interaction behaviors and subsequent independent performance.

It has long been theorized that, after the so-called critical period has passed, acquiring language becomes a more difficult enterprise. While general differences between adult second language (L2) learners and normally developed child (L1) acquirers have been more or less empirically established, a strand of recent L2 accounts have focused on the specific locus of these differences. The main goal of this dissertation project is to test the predictions of one such account: Clahsen and Felser's Shallow Structure Hypothesis (SSH; Clahsen & Felser 2006a, 2006b). The SSH places emphasis on the empirical testing of native/non-native language processing asymmetries, which are argued to be due to less detailed L2 grammatical representations. This dissertation tests the predictions of the SSH using a long-distance dependency: Clitic Left Dislocation (CLLD) in L2 Spanish. The study includes on-line and an off-line tasks, which were completed by a control group of native speakers of Spanish and an experimental group constituted by L2 learners of Spanish whose first language was English. In view of the well-known fact that L2 learning outcomes vary widely across individuals, a secondary goal of this dissertation project is to determine whether variability in individual learning abilities, such as inhibitory control and statistical learning predicts variability in L2 learning. Part of L2 learning involves detecting the probabilistic patterns of a language (Saffran, Aslin, & Newport, 1996), such that individuals who are better pattern learners may be better able to learn the structural regularities of the L2 input. Results were analyzed in order to determine whether the predictions of the SSH could account for the patterns present in the data. These results suggest that although the acquisition of long-distance dependencies is a protracted process, both intermediate and advanced L2 learners of Spanish could anticipate (predict) a syntactic element based in previously occurring cues. Thus, these results fail to support the predictions of the SSH. In terms of individual differences, overall, neither statistical learning nor inhibitory control appear to modulate the on-line processing of this particular long-distance dependency in Spanish.
