Evidence has shown that the insulin and insulin receptor (IR) play a role in cognitive function. However, the detailed mechanisms underlying insulin's action on learning and memory are not yet understood. Here we investigated changes in long-term memory-associated expression of the IR and downstream molecules in the rat hippocampus. After…

This keynote article proposes a new model of language development based on processing, the sole mechanism of acquisition for the Acquisition by Processing Theory (APT). The language module--adapted from Jackendoff's distinction between integration (building complex structures) and interface (facilitating information transfer at the intersections…

Research findings concerning working memory impairment of children with learning disabilities, poor readers, and individuals with severe learning difficulties are examined within the framework of working memory. Results from developmental and experimental studies indicate a close link between the function of working memory and performance on…

Teachers intuitively recognize the importance of metacognition but may not be aware of its many dimensions. Mr. Martinez explores the varieties of metacognitive skills and then offers suggestions for cultivating them in learners of all ages. (Contains 4 endnotes.)

The conceptual level, working memory capacity and domain-specific skills of two girls (aged 7 and 11 years old) and two boys (aged 9 and 10 years old) who displayed exceptional intellectual performance were investigated from Case's neo-Piagetian theoretical perspective. Five measures of conceptual level and two measures of working memory capacity…

The executive attention theory of working memory capacity (WMC) proposes that measures of WMC broadly predict higher order cognitive abilities because they tap important and general attention capabilities (R. W. Engle & M. J. Kane, 2004). Previous research demonstrated WMC-related differences in attention tasks that required restraint of habitual…

The effect of a prior gist-based versus item-specific retrieval orientation on recognition of objects and words was examined. Prior item-specific retrieval increased item-specific recognition of episodically related but not previously tested objects relative to both conceptual- and perceptual-gist retrieval. An item-specific retrieval advantage…

Examines the utility of teaching reading using rime-based reading strategies with prereaders. Measures rhyming, phoneme identity, letter-sound knowledge, phonological working memory, First Nations language speaking ability, and reading. Concludes that progress in phonological awareness and word reading can be enhanced in prereaders by adding…

After hemispherectomy (removal or disconnection of an entire cerebral hemisphere) in childhood for treatment of intractable epilepsy, gross speech and language functions are often rescued. Whether more complex functions, such as syntactic processing, are selectively impaired, remains controversial. Here we present a cross-sectional study of…

Since learning English is very popular in non-English speaking countries, developing modern assisted-learning tools that support effective English learning is a critical issue in the English-language education field. Learning English involves memorization and practice of a large number of vocabulary words and numerous grammatical structures.…

Purpose: There is little empirical translation of multimodal cognitive activity programs in "real-world" community-based settings. This study sought to demonstrate in a short-term pilot randomized trial that such an activity program improves components of cognition critical to independent function among sedentary older adults at greatest risk.…

Background: The object of this study was to analyze the executive functioning of children with attention deficit hyperactivity disorder (ADHD) or reading disability (RD) independent of their non-executive deficits. Methods: Three carefully diagnosed groups of children, aged between 7 and 12 years (35 ADHD, 22 RD and 30 typically developing…

This article first examines recent theoretical and empirical research on reading development and instruction in English-speaking countries. Then, a study is described that examines the effects of a synthetic phonics-emphasis Direct Instruction remedial reading program on the phonological processes of students, with teacher-identified serious…

Cognitive performance is affected by an individual's characteristics and the environment, as well as by the nature of the task and the amount of practice at it. Mental performance tests range in complexity and include subjective estimates of mood, simple objective tests (reaction time), and measures of complex performance that require decisions to…

Background: Narratives have been used by a number of researchers to investigate the language of children with specific language impairment (SLI). While a number of explanations for SLI have been proposed, there is now mounting evidence that children with SLI have limited memory resources. Phonological memory has been the focus of the research on…
