This thesis explores cross-linguistic structural phenomena in the language production of bilinguals in the specific context of translation. In recent years, cross-linguistic phenomena on the level of syntax have become an increasingly prominent issue in psycholinguistic research, and are a well-known feature in language productions of multilinguals, from language learners to translators. The work presented in this thesis takes current perspectives from psycholinguistics (discussed in Chapter 2) as its foundation; impulses from research on bilingualism and advanced Second Language Acquisition (Chapter 3) and Translation and Interpreting (Chapter 4) allow to develop a specific approach to translation as a special instance of bilingual production, elementary concepts of which are available to all bilingual speakers. On this basis, an experimental paradigm for psycholinguistic research into structural phenomena of translation is developed and refined (Chapters 5 and 6) that allows to access both off-line and on-line data from simple text-to-speech translations. Experiment 1 (Chapter 5) confirms the existence of priming-like, on-line facilitation in translations where source and target sentences are structurally matched. Experiment 2 (Chapter 6) obtains a structural priming effect from sources where several target structures are available, and refines material specifications for the experimental paradigm and analysis techniques for on-line data. In Experiment 3 (Chapter 7), off-line structural priming is observed in translations into and out of L2. The corresponding on-line facilitation of primed productions, however, is discovered only in translations from L1 to L2, a finding that agrees with predictions from research in L2 acquisition and translation. On this basis, Experiment 3 is repeated in Experiment 4 (Chapter 8) with a modification to materials so that an additional restructuring operation becomes necessary. Although structural priming is still evident in translations from L1 to L2, on-line facilitation is not, suggesting that syntactic operations do not add to each other but are processed in one go. Results are discussed comprehensively (in Chapter 9) with respect to their entailments for adjacent fields of research, in particular with a view to theories of syntactic production and directionality in translation. Several possibilities for future applications of the approach are proposed.

During language production, conceptual messages are encoded into a target language and articulated. Existing models of language production assume several stages of processing including a conceptual level, a level where lexical selection and syntactic processing occurs and a level where morphological and phonological features are added ready for production (e.g. Levelt et al., 1999). Previous research has considered how lexical and syntactic information could be stored via lemma (Kempen & Huijbers, 1983), syntactic nodes (Levelt at el., 1999) and combinatorial nodes (Pickering & Braingan, 1998), but little is understood about how syntactic structures are selected. This thesis examines how constituent structures are selected by investigating choice of structure in unbounded dependencies such as Which jug with the red spots is the nun giving the monk? and how this is affected by factors such as verb-subcategorisation preferences and global sentence structure complexity. A series of language production experiments investigate how global structure complexity and verb-subcategoricatisaion preferences affect choice of syntactic structure at the clause level in unbounded dependencies. A picture description task reveals an unusual preference for the dispreferred passive voice structure as a result of global structural complexity. Sentence recall experiments demonstrate that both global structural complexity and verb-subcategorisation preferences can affect choice of structure and that competition between these factors decides the final structure. Finally, syntactic priming experiments show that processing mechanisms are shared between simple matrix clause structures and unbounded dependency clause structures, but that the influence of these shared mechanisms vary between the different structure types. This could be attributed to a modal of processing where choice of structure is decided by competition between structure representations which are influenced by different factors in different global syntactic conditions. The results suggest that choice of syntactic structure is decided through competition between possible structures. These possible structures may receive further activation or inhibition from other factors such as global structural complexity or verb-subcategorisation preferences and thematic fit. Global structural complexity may influence structure preferences through increased processing load or through attempts to integrate the clause structure with another global structure. Thematic role arguments may influence structure through a preference that syntactic roles fit with specified thematic roles. (e.g. experiencer as subject). This model assumes parallel processing of possible structures and individual structures within a complex larger structure. It also assumes an incremental model of processing which attempts to integrate structures as soon as possible.

It has long been known that word length has a larger influence on the recognition of words presented in the left visual field than the right visual field, an effect commonly referred to as the length by visual field interaction. The aim of the present thesis was to explore the neural and behavioural effects of the length by visual field interaction. In doing so, it was expected that the results would contribute to and extend the body of behavioural research in this area, particularly in regard to the hemispheric processing of words. Chapter One presents a general overview of the thesis; in Chapter Two, the nature of the right visual field advantage is reviewed, with particular reference to previous work that has demonstrated differential effects of word length in each of the cerebral hemispheres. Models that seek to account for visual field asymmetries are also reviewed. Chapter Three outlines the key methods adopted in the thesis, namely, the divided visual field task and the use of event-related potentials. Chapters Four and Five present the results of two experiments that explored the neural effect of increasing word length in each of the hemispheres. The results provided ERP evidence of early processing dissociations between the hemispheres in terms of words and non-words of different lengths. Experiments 3-6 explored the effect of orthographic uniqueness point in each of the visual fields, as a means of exploring the nature of processing conducted by each hemisphere. Across three experiments, it was shown that words with a late uniqueness point were recognised faster and more accurately than words with an early uniqueness point. This facilitation for late uniqueness point words was evident in the ERP response at 170ms. Furthermore, orthographic uniqueness point was shown to differentially affect each of the hemispheres. Experiments 6-9 provided evidence to suggest that the interaction of length and visual field was influenced by orthographic depth, a property of language that reflects the transparency with which sounds are represented in print. In Chapter Ten, the effect of format distortion on the interaction of length and visual field was explored. Finally, Chapter Ten summarises and discuss the key findings of the present thesis in light of theories that seek to account for lateralised word recognition.

This thesis examined the processes involved in reading and recognising acronyms (e.g. BBC, HIV, NATO). Normative values for frequency, age of acquisition, imageability, length, bigram and trigram frequency and orthographic neighbourhood size have been collected, and the influence of these factors on reading, recognition (Chapter 3) and word association responses (Chapter 4) has been assessed. Findings suggest that acronyms are integrated alongside words in the mental lexicon, and that meaning and phonology are particularly important in acronym processing. Chapter 5 extended these findings by investigating the performance of a patient with a specific deficit in semantic processing (semantic dementia). Some acronyms, specifically those which are pronounced by naming each letter in turn, were found to pose few problems for this patient even after her semantic system had been adversely affected by her disorder. Chapter 7 reported an event-related potential study of acronyms, with reference to the N170 and Recognition Potential components. The electrophysiological data supported the interpretation of acronyms as lexical, and particularly influenced by print to pronunciation factors. Findings of the thesis as a whole were discussed in relation to the Dual Route Cascaded model (Coltheart, Perry, Rastle, Langdon & Ziegler, 2001) and the Triangle model (Plaut, Seidenberg & Patterson, 1996). It was concluded that neither model could adequately accommodate acronym reading and recognition processes as they currently stand. Suggestions for amendments to word reading models were made. Potential future research directions are also discussed.

Syntactically ambiguous sentences offer an insight into how sentences generally are processed, by examining how readers recognise and reanalyse the ambiguity. However, it is only more recently that the comprehension product of syntactic analysis has been adequately tested, demonstrating that ambiguities are not always fully processed. This work has led to the good-enough approach to language processing and comprehension (e.g., Ferreira & Patson, 2007), which argues that sentence processing is merely good enough for the current task, and that our comprehension may not exactly match the content of what has been read. The work presented in this thesis set out to examine what it means for syntactic ambiguity processing to be good enough, by monitoring patterns of eye movements as people read sentences containing a temporary syntactic ambiguity. Comprehension questions probed the extent to which the syntactic ambiguity had been resolved. Across six experiments, it was demonstrated that both online sentence processing and comprehension are influenced by the presence of an extrinsic memory load, the presence or absence of comprehension questions, the length of texts being read, and the age of participants. Eye movement patterns were more superficial if the task permitted it; similarly, syntactic ambiguities were misinterpreted more commonly as the task demands increased. The results support a good-enough, adaptive sentence processing system, where initial misinterpretations can linger in the product of syntactic analysis, and which is affected by task demands and individual differences.
