The acquisition of adjunct control: grammar and processing

This dissertation uses children’s acquisition of adjunct control as a case study to investigate grammatical and performance accounts of language acquisition. In previous research, children have consistently exhibited non-adultlike behavior for sentences with adjunct control. To explain children’s behavior, several different grammatical accounts have been proposed, but evidence for these accounts has been inconclusive. In this dissertation, I take two approaches to account for children’s errors. First, I spell out the predictions of previous grammatical accounts, and test these predictions after accounting for some methodological concerns that might have influenced children’s behavior in previous studies. While I reproduce the non-adultlike behavior observed in previous studies, the predictions of previous grammatical accounts are not borne out, suggesting that extragrammatical factors are needed to explain children’s behavior. Next, I consider the role of two different types of extragrammatical factors in predicting children’s non-adultlike behavior. With a new task designed to address the task demands in previous studies, children exhibit significantly higher accuracy than with previous tasks. This suggests that children’s behavior has been influenced by task- specific processing factors. In addition to the task, I also test the predictions of a similarity-based interference account, which links children’s errors to the same memory mechanisms involved in sentence processing difficulties observed in adults. These predictions are borne out, supporting a more continuous developmental trajectory as children’s processing mechanisms become more resistant to interference. Finally, I consider how children’s errors might influence their acquisition of adjunct control, given the distribution in the linguistic input. I discuss the results of a corpus analysis, including the possibility that adjunct control could be learned from the input. The kinds of information that could be useful to a learner become much more limited, however, after considering the processing limitations that would interfere with the representations available to the learner.

Parsing, Generation and Grammar

Humans use their grammatical knowledge in more than one way. On one hand, they use it to understand what others say. On the other hand, they use it to say what they want to convey to others (or to themselves). In either case, they need to assemble the structure of sentences in a systematic fashion, in accordance with the grammar of their language. Despite the fact that the structures that comprehenders and speakers assemble are systematic in an identical fashion (i.e., obey the same grammatical constraints), the two ‘modes’ of assembling sentence structures might or might not be performed by the same cognitive mechanisms. Currently, the field of psycholinguistics implicitly adopts the position that they are supported by different cognitive mechanisms, as evident from the fact that most psycholinguistic models seek to explain either comprehension or production phenomena. The potential existence of two independent cognitive systems underlying linguistic performance doubles the problem of linking the theory of linguistic knowledge and the theory of linguistic performance, making the integration of linguistics and psycholinguistic harder. This thesis thus aims to unify the structure building system in comprehension, i.e., parser, and the structure building system in production, i.e., generator, into one, so that the linking theory between knowledge and performance can also be unified into one. I will discuss and unify both existing and new data pertaining to how structures are assembled in understanding and speaking, and attempt to show that the unification between parsing and generation is at least a plausible research enterprise. In Chapter 1, I will discuss the previous and current views on how parsing and generation are related to each other. I will outline the challenges for the current view that the parser and the generator are the same cognitive mechanism. This single system view is discussed and evaluated in the rest of the chapters. In Chapter 2, I will present new experimental evidence suggesting that the grain size of the pre-compiled structural units (henceforth simply structural units) is rather small, contrary to some models of sentence production. In particular, I will show that the internal structure of the verb phrase in a ditransitive sentence (e.g., The chef is donating the book to the monk) is not specified at the onset of speech, but is specified before the first internal argument (the book) needs to be uttered. I will also show that this timing of structural processes with respect to the verb phrase structure is earlier than the lexical processes of verb internal arguments. These two results in concert show that the size of structure building units in sentence production is rather small, contrary to some models of sentence production, yet structural processes still precede lexical processes. I argue that this view of generation resembles the widely accepted model of parsing that utilizes both top-down and bottom-up structure building procedures. In Chapter 3, I will present new experimental evidence suggesting that the structural representation strongly constrains the subsequent lexical processes. In particular, I will show that conceptually similar lexical items interfere with each other only when they share the same syntactic category in sentence production. The mechanism that I call syntactic gating, will be proposed, and this mechanism characterizes how the structural and lexical processes interact in generation. I will present two Event Related Potential (ERP) experiments that show that the lexical retrieval in (predictive) comprehension is also constrained by syntactic categories. I will argue that the syntactic gating mechanism is operative both in parsing and generation, and that the interaction between structural and lexical processes in both parsing and generation can be characterized in the same fashion. In Chapter 4, I will present a series of experiments examining the timing at which verbs’ lexical representations are planned in sentence production. It will be shown that verbs are planned before the articulation of their internal arguments, regardless of the target language (Japanese or English) and regardless of the sentence type (active object-initial sentence in Japanese, passive sentences in English, and unaccusative sentences in English). I will discuss how this result sheds light on the notion of incrementality in generation. In Chapter 5, I will synthesize the experimental findings presented in this thesis and in previous research to address the challenges to the single system view I outlined in Chapter 1. I will then conclude by presenting a preliminary single system model that can potentially capture both the key sentence comprehension and sentence production data without assuming distinct mechanisms for each.

THE ROLE OF RULES, EXAMPLES AND INDIVIDUAL DIFFERENCES IN THE ACQUISITION OF DECLARATIVE AND PROCEDURAL SECOND LANGUAGE KNOWLEDGE

The relevance of explicit instruction has been well documented in SLA research. Despite numerous positive findings, however, the issue continues to engage scholars worldwide. One issue that was largely neglected in previous empirical studies - and one that may be crucial for the effectiveness of explicit instruction - is the timing and integration of rules and practice. The present study investigated the extent to which grammar explanation (GE) before practice, grammar explanation during practice, and individual differences impact the acquisition of L2 declarative and procedural knowledge of two grammatical structures in Spanish. In this experiment, 128 English-speaking learners of Spanish were randomly assigned to four experimental treatments and completed comprehension-based task-essential practice for interpreting object-verb (OV) and ser/estar (SER) sentences in Spanish. Results confirmed the predicted importance of timing of GE: participants who received GE during practice were more likely to develop and retain their knowledge successfully. Results further revealed that the various combinations of rules and practice posed differential task demands on the learners and consequently drew on language aptitude and WM to a different extent. Since these correlations between individual differences and learning outcomes were the least observed in the conditions that received GE during practice, we argue that the suitable integration of rules and practice ameliorated task demands, reducing the burden on the learner, and accordingly mitigated the role of participants’ individual differences. Finally, some evidence also showed that the comprehension practice that participants received for the two structures was not sufficient for the formation of solid productive knowledge, but was more effective for the OV than for the SER construction.

Brúnkahk Tek: An Extinct Language

En Costa Rica hay seis lenguas indígenas reconocidas oficialmente. Cada una de ellas disfruta de una condición diferente en cuanto a sus tradiciones y números de hablantes, entre otras. A pesar de los esfuerzos del gobierno de Costa Rica y otros investigadores desde 1995, las lenguas han enfrentado dificultades a nivel interno y externo, las cuales han resultado en el debilitamiento o inclusive pérdida de las mismas. Esto nos lleva al caso de boruca, una de las lenguas de Costa Rica que puede ahora ser considerada una lengua extinta. Este artículo presenta una descripción general del pueblo boruca, sus tradiciones y sus principales características, y a la vez ofrece al lector una descripción tipológica general de la lengua en la cual se discuten brevemente los rasgos generales de su gramática.In Costa Rica there are six officially recognized indigenous languages. Each enjoys a different condition in terms of its traditions and number of speakers, among others. Despite efforts of the Costa Rican government and other researchers since 1995, the languages have met endogenous and exogenous difficulties that have resulted in the weakening and even loss of the languages. This leads us to what happened to Boruca, one of the indigenous languages of Costa Rica which can now be considered an extinct language. This article presents a general description of the Boruca people, their traditions and main characteristics, and it also introduces the reader to a general typological description of the language where the main features of its grammar are briefly discussed.

An investigation into the effect of play-based instruction on the development of play skills and oral language: a 6-month longitudinal study

The current study investigated the influence of a play-based curriculum on the development of pretend play skills and oral language in children attending their first year of formal schooling. In this quasi-experimental design, two groups of children were followed longitudinally across the first 6 months of their first year at school. The children in the experimental group were attending a school with a play-based curriculum; the children in the control group were attending schools following a traditional curriculum. A total of 54 children (Time 1 M age = 5;6, range: 4;10–6;2 years) completed standardised measures of pretend play and narrative language skills upon school entry and again 6 months later. The results showed that the children in the play-based group significantly improved on all measures, whereas the children in the traditional group did not. A subset of the sample of children (N = 28, Time 1 M age = 5;7, range: 5;2 – 6;1) also completed additional measures of vocabulary and grammar knowledge, and a test of non-verbal IQ. The results suggested that, in addition to improving play skills and narrative language ability, the play-based curriculum also had a positive influence on the acquisition of grammar.

Putting grammar in its place: interactions and identity in a Master of TESOL course

This chapter reports on the development of language awareness and second language identities of a cohort of Chinese TESOL teachers that arose as a result of incidental classroom interactions during a TESOL Masters course in Australia. The experiences of such interactions appeared to help the Chinese teachers make stronger connections between form and meaning, and, while they also reflected deeply on the pedagogies of grammar, they gained a wider view of language teaching and learning that included pragmatic and sociolinguistic awareness. The impact of cultural and educational exchanges and the resulting formations of second language identities is an emerging focus of research (Benson, Barkhuizen, Bodycott and Brown, 2013). In the field of TESOL, such movements and exchanges are creating opportunities to develop a richer discourse, by drawing on diverse traditions of professionalism in different communities and contexts, and calls are increasingly being made for a plural professional knowledge and more inclusive relationships (Canagarajah, 2005; Holliday, 2005; Widdowson, 2004). The People’s Republic of China has been one of the major contributors to student and teacher mobility in recent years; English language is now a priority subject in China, and all students entering university must take the English college test whether they intend to major in English or not, and therefore there has been much interest in upskilling cohorts of Chinese teachers of English to meet this demand. An increasingly typical initiative is to award scholarships to gain professional qualifications in English-speaking countries. A cohort of English teachers from Jiangsu province, China, is the focus of the present study. During their Masters in TESOL course in Queensland, Australia, they experienced interactions with native speakers inside and outside of the classroom. As their course lecturer for several TESOL units, I was interested in the nature of the incidental language awareness arising from course activities with their native-speaking peers. I was also interested in whether they felt that these experiences had implications for their sense of identity in a second language. The following sections therefore discuss the key themes: interaction in higher education contexts, language awareness, and second language identities.

Lost (and found) in translation: learning from German language educators

This essay introduces two presentations (or Vorträge) by Ulf Abraham and Thomas Zabka that were originally published in the German journal, Didaktik Deutsch. I reflect on the complexities of translation and intercultural communication, and ask how we might meaningfully compare the policy environment of one country with that of another. In this era of globalisation and standards-based reforms it is easy to suppose that those reforms are the same everywhere. The essays by Abraham and Zabka, however, provide insights into a policy environment where debates about the importance of language and literature are being played out differently vis-à-vis standards-based reforms than is the case in the Anglophone world. I ask what we can learn from these essays, and how the insights they provide might be applied in an Anglophone context.
