This study compares monolinguals and different kinds of bilinguals with respect to their knowledge of the type of lexical phenomenon known as collocation. Collocations are word combinations that speakers use recurrently, forming the basis of conventionalized lexical patterns that are shared by a linguistic community. Examples of collocations…

Most models of human performance on the traveling salesperson problem involve clustering of nodes, but few empirical studies have examined effects of clustering in the stimulus array. A recent exception varied degree of clustering and concluded that the more clustered a stimulus array, the easier a TSP is to solve (Dry, Preiss, & Wagemans,…

Orientation dependence in spatial memory has often been interpreted in terms of accessibility: Object locations are encoded relative to a reference orientation that affords the most accurate access to spatial memory. An open question, however, is whether people naturally use this "preferred" orientation whenever recalling the space. We…

When asked to search for a target letter while reading, the patterns with which people miss the target letter reveal information about the process of reading itself. Questions remain as to whether this paradigm reflects normal reading processes however. We used a novel continuous-performance neuroimaging paradigm to address this question. In…

This paper investigates the role of amount of current and "cumulative" exposure in bilingual development and ultimate attainment by exploring the extent to which simultaneous bilingual children's knowledge of grammatical gender is affected by current and previous amount of exposure, including in the early years. Elicited production and…

Selective attention in the presence of distraction is a key aspect of healthy cognition. The underlying neurobiological processes, have not, however, been functionally well characterized. In the present study, we used functional magnetic resonance imaging to determine how ecologically relevant distracting noise affects cortical activity in 27…

Children are notoriously bad at delaying gratification to achieve later, greater rewards (e.g., Piaget, 1970)--and some are worse at waiting than others. Individual differences in the ability-to-wait have been attributed to self-control, in part because of evidence that long-delayers are more successful in later life (e.g., Shoda, Mischel, &…

The present study examines the nature of the Spanish rhotics experimentally, investigating the possibilities that the trill is best understood as deriving from an underlying geminate or that the tap and trill may be separate phonemes. In order to explore these two theories, a behavioral task was designed exploiting the absence of native words in…

Many recent models of learning and instruction center learning on real-world tasks and problems to support knowledge application and transfer. Among these models are problem-based learning and task-centered learning, two different approaches to learning that are often mistaken for one another. However, there are important distinctions between…

Training effectiveness depends on conducting a thorough needs assessment. Traditional needs assessment methods are insufficient for today's business environment characterized by rapid pace, risk, and uncertainty. To overcome the deficiencies of traditional needs assessment methods, a narrative-based unstructured interview approach with subject…

Previous research has shown that high phonotactic frequencies facilitate the production of regularly inflected verbs in English-learning children with specific language impairment (SLI) but not with typical development (TD). We asked whether this finding can be replicated for German, a language with a much more complex inflectional verb paradigm…

This study tests the hypothesis that developmental dyslexia is (partly) caused by a deficit in implicit sequential learning, by investigating whether infants at familial risk of dyslexia can track non-adjacent dependencies in an artificial language. An implicit learning deficit would hinder detection of such dependencies, which mark grammatical…

Children start producing ["necessary and sufficient"] conditionals relatively late. Past counterfactuals (PCFs), for example "If she had shut the cage, the rabbit wouldn't have escaped", are particularly problematic for children; despite evidence of comprehension in the preschool years, children aged eleven are still making…

The goals of the current study were (a) to assess differences in child and adult pausing and (b) to determine whether characteristics of child and adult pausing can be explained by the same language variables. Spontaneous speech samples were obtained from 10 5-year-olds and their accompanying parent using a storytelling/retelling task. Analyses of…

Training can improve perceptual sensitivities. We examined whether the temporal dynamics and the incidental versus intentional nature of training are important. Within the context of a birdsong rate discrimination task, we examined whether the sequencing of pretesting exposure to the stimuli mattered. Easy-to-hard (progressive) sequencing of…
