The purpose of the present study was to investigate incidental sequence learning across the lifespan. We tested 50 children (aged 7-16), 50 young adults (aged 20-30), and 50 older adults (aged >65) with a sequence learning paradigm that involved both a task and a response sequence. After several blocks of practice, all age groups slowed down…

This article provides experimental evidence for the claim in Hayes (2004) and McCarthy (1998) that language learners are biased to assume that morphological paradigms should be phonologically-uniform--that is, that derived words should retain all the phonological properties of their bases. The evidence comes from an artificial language…

Objective: This study was designed to extend the use of a memory training technique, known as the repetition-lag procedure, to Alzheimer patients. The specificity of this procedure is to target the process of recollection for improvement. Method: A group of 12 patients were trained individually for 6 h. The training procedure consisted of a series…

Although previous research has identified contemporaneous associations between cognitive deficits and symptom phenotypes in Attention Deficit/Hyperactivity Disorder, no studies have as yet attempted to identify direction of effect. The present study used cross-lagged path modeling to examine competing hypotheses about longitudinal associations…

In representation-rich domains such as organic chemistry, students must be facile and accurate when translating between different 2D representations, such as diagrams. We hypothesized that translating between organic chemistry diagrams would be more accurate when concrete models were used because difficult mental processes could be augmented by…

This article presents an examination of the language demands of cognitively demanding tasks and proposes an initial framework for the language demands of higher-order mathematics thinking practices. We articulate four categories for this framework: "language of generalisation," "language of comparison," "language of proportional reasoning," and…

Background: Cognitive models of bipolar I disorder (BD) may aid in identification of children who are especially vulnerable to chronic mood dysregulation. Information-processing biases related to memory and attention likely play a role in the development and persistence of BD among adolescents; however, these biases have not been extensively…

This article examines the stance options used by writers responding to a data description task in the discipline of Statistics. Based on a small learner corpus, it uses inductive qualitative content analysis to explore both the content propositions that students included in their writing, and the ways in which they expressed evaluative stance…

Moment to moment, a writer faces a host of potential problems. How does the writer's mind coordinate this problem solving? In the original Hayes and Flower model, the authors posited a distinct process to manage this coordinating--that is, the "monitor." The monitor became responsible for executive function in writing. In two…

When contexts are framed expansively, students are positioned as actively contributing to larger conversations that extend across time, places, and people. A set of recent studies provides empirical evidence that the expansive framing of contexts can foster transfer. In this article, we present five potentially complementary explanations for how…

This study was an investigation of how particular processing tasks influence L2 reading in relation to text type effects and L2 reading proficiency. Two groups of Japanese university EFL students (N = 103), varying in English reading proficiency, read a narrative passage and an expository passage in one of three task conditions: outlining,…

Perhaps now more than ever before the U.S. military is called on to perform tasks that are outside its normal/traditional purview. Recent wars--Bosnia, Afghanistan, and Iraq, for example--have demonstrated the need for the U.S. military to do more than find and defeat a clearly defined enemy. At all levels of the war theater (conflict area), the…

The study examined individual differences in code-switching to determine the relationship between code-switching frequency and performance in verbal and non-verbal task switching. Seventy-eight Cantonese-English bilinguals completed a semi-structured conversation to quantify natural code-switching, a verbal fluency task requiring language…

Background: Rhyme awareness is one of the earliest forms of phonological awareness to develop and is assessed in many developmental studies by means of a simple rhyme task. The influence of more demanding experimental paradigms on rhyme judgment performance is often neglected. Addressing this issue may also shed light on whether rhyme processing…

Age of acquisition (AoA) effects have been used to support the notion of a critical period for first language acquisition. In this study, we examine AoA effects in deaf British Sign Language (BSL) users via a grammaticality judgment task. When English reading performance and nonverbal IQ are factored out, results show that accuracy of…
