There is a large body of research indicating that L2 learners often have trouble with the word form. Learners often transfer their L1 processing routines over to the L2 in their attempt to process the L2 forms, whether those routines are appropriate to the L2 form system or not. This study explores the problems of learning L2 vocabulary word form…

The immediate and long-term neural correlates of linguistic processing deficits reported following paediatric and adolescent traumatic brain injury (TBI) are poorly understood. Therefore, the current research investigated event-related potentials (ERPs) elicited during a semantic picture-word priming experiment in two groups of highly functioning…

Previous evidence has shown that word pairs that are either related in form (e.g., "ruc-berro"; donkey-watercress) or very closely semantically related (e.g., "ruc-caballo", donkey-horse) produce interference effects in a translation recognition task (Ferre et al., 2006; Guasch et al., 2008). However, these effects are not…

The influence of diet on cortical processing of syllables was examined at 3 and 6 months in 239 infants who were breastfed or fed milk or soy-based formula. Event-related potentials to syllables differing in voice-onset-time were recorded from placements overlying brain areas specialized for language processing. P1 component amplitude and latency…

Decision-makers effortlessly balance the need for urgency against the need for caution. Theoretical and neurophysiological accounts have explained this tradeoff solely in terms of the "quantity" of evidence required to trigger a decision (the "threshold"). This explanation has also been used as a benchmark test for evaluating…

This dissertation examines the influence of lexical-semantic representations, conceptual similarity, and contextual fit on the processing of coordinated verb phrases. The study integrates information gleaned from current linguistic theory with current psycholinguistic approaches to examining the processing of coordinated verb phrases. It has…

Previous research has found that the recent processing of a linguistic form (e.g. word or syntactic pattern) facilitates its reuse. A separate line of research has found that the appearance of a linguistic form in certain structural contexts (e.g. the focus position of a cleft sentence) can increase the likelihood of a form's reuse. However, these…

Learning to associate auditory information of speech sounds with visual information of letters is a first and critical step for becoming a skilled reader in alphabetic languages. Nevertheless, it remains largely unknown which brain areas subserve the learning and automation of such associations. Here, we employ functional magnetic resonance…

The goal of the present study was to investigate the electrophysiological correlates of second-language (L2) morphosyntactic processing in highly proficient late learners of an L2 with long exposure to the L2 environment. ERPs were collected from 22 English-Spanish late learners while they read sentences in which morphosyntactic features of the L2…

A study combining artificial grammar and sentence comprehension methods investigated the learning and online use of probabilistic, nonadjacent combinatorial constraints. Participants learned a small artificial language describing cartoon monsters acting on objects. Self-paced reading of sentences in the artificial language revealed comprehenders'…

The interface between the conceptual and lexical systems was investigated in a word production setting. We tested the effects of two conceptual dimensions--semantic category and visual shape--on the selection of Chinese nouns and classifiers. Participants named pictures with nouns ("rope") or classifier-noun phrases ("one-"classifier"-rope") in…

Recent investigations have supported the suggestion that phonological speech errors may reflect the simultaneous activation of more than one phonemic representation. This presents a challenge for speech error evidence which is based on the assumption of well-formedness, because we may continue to perceive well-formed errors, even when they are not…

Nuances in how adults talk about ability may have important consequences for children's sustained involvement and success in an activity. In this study, I tested the hypothesis that children would be less motivated while performing a novel activity if they were told that boys or girls in general are good at this activity (generic language) than if…

In the Dimension Change Card Sort (DCCS) task, 3-year-olds can sort cards well by one dimension but have difficulty in switching to sort the same cards by another dimension when asked; that is, they perseverate on the first relevant information. What is the information that children perseverate on? Using a new version of the DCCS, the experiments…

Intensional verbs like "want" select for clausal complements expressing propositions, though they can be perfectly natural when combined with a direct object. There are two interesting phenomena associated with intensional transitive expressions. First, it has been suggested that their interpretation requires enriched compositional operations,…
