Reading involves mapping combinations of a learned visual code (letters) onto meaning. Previous studies have shown that when visual word recognition is challenged by visual degradation, one way to mitigate these negative effects is to provide "top-down" contextual support through a written congruent sentence context. Crowding is a…

We explore the following two cognitive questions regarding crosslinguistic variation in lexical semantic systems: Why are some linguistic categories--that is, the associations between a term and a portion of the semantic space--harder to learn than others? How does learning a language-specific set of lexical categories affect processing in that…

The present research examines the role of music and dance in motivating Gaelic language learning on Cape Breton Island (Canada). The Gaelic language, once thriving in this context, has declined in use but flourishes in both music and dance. This article presents the results of in-depth interviews (60-90 minutes) with 10 accomplished adult…

Three alternative mechanisms for age-related decline in memory search have been proposed, which result from either reduced processing speed (global slowing hypothesis), overpersistence on categories (cluster-switching hypothesis), or the inability to maintain focus on local cues related to a decline in working memory (cue-maintenance hypothesis).…

We report two visual-world eye-tracking experiments that investigated the effects of subjecthood, pronominalisation, and contrastive focus on the interpretation of pronouns in subsequent discourse. By probing the effects of these factors on real-time pronoun interpretation, we aim to contribute to our understanding of how topicality-related…

The lexical decision (LD) and naming (NAM) tasks are ubiquitous paradigms that employ printed word identification. They are major tools for investigating how factors like morphology, semantic information, lexical neighborhood and others affect identification. Although use of the tasks is widespread, there has been little research into how…

We describe a multiple-route model of reading development in which coarse-grained orthographic processing plays a key role in optimizing access to semantics via whole-word orthographic representations. This forms part of the direct orthographic route that gradually replaces phonological recoding during the initial phases of reading acquisition.…

We report three experiments on reference resolution in Dutch. The results of two off-line experiments and an eye-tracking study suggest that the interpretation of different referential forms--in particular, "emphatic" strong pronouns, weak pronouns, and demonstrative pronouns--cannot be satisfactorily explained in terms of a single…

Change blindness describes the surprising difficulty of detecting large changes in visual scenes when changes occur during a visual disruption. In order to study the developmental course of this phenomenon, a modified version of the flicker paradigm, based on Rensink, O'Regan & Clark (1997), was given to three groups of children aged 6-12 years…

This study investigated whether Foygel and Dell's (2000) interactive two-step model of speech production could simulate the number and type of errors made in picture-naming by 68 children of elementary-school age. Results showed that the model provided a satisfactory simulation of the mean error profile of children aged five, six, seven, eight and…

Semantically reversible sentences are prone to misinterpretation and take longer for typically developing children and adults to comprehend; they are also particularly problematic for those with language difficulties such as aphasia or Specific Language Impairment. In our study, we used fMRI to compare the processing of semantically reversible and…

Recent research on children's inferencing has found that although adults typically adopt the pragmatic interpretation of "some" (implying "not all"), 5- to 9-year-olds often prefer the semantic interpretation of the quantifier (meaning possibly "all"). Do these failures reflect a breakdown of pragmatic competence or the metalinguistic demands of…

The purpose of this dissertation is to investigate the processing mechanisms of non-native English speakers at both the sentence level and the morphological level, addressing the issue of whether adult second language (L2) learners qualitatively differ from native speakers in processing linguistic input. Using psycholinguistic on-line techniques…

We report a new study testing our proposal that word learning may be best explained as an approximate form of Bayesian inference (Xu & Tenenbaum, in press). Children are capable of learning word meanings across a wide range of communicative contexts. In different contexts, learners may encounter different sampling processes generating the examples…

This experiment examined event-related responses to targets preceded by semantically transparent morphologically related primes (e.g., farmer-farm), semantically opaque primes with an apparent morphological relation (corner-corn), and orthographically, but not morphologically, related primes (scandal-scan) using the masked priming technique…
