Two distinctly different maturational processes--cortical thinning and white matter maturation--take place in the brain as we mature from late childhood to adulthood. To what extent does each contribute to the development of complex cognitive functions like working memory? The independent and joint contributions of cortical thickness of regions of…

We examined the ERP correlates of familiarity and recollection and their development in 8- to 10-year-old children and a control group of young adults. Capitalizing on the different temporal dynamics of familiarity and recollection, we tested recognition memory in both groups with a speeded and nonspeeded response condition. Consistent with the…

Six young adults practiced for 36 sessions on a working-memory updating task in which 2 digits and 2 spatial positions were continuously updated. Participants either did 1 updating operation at a time, or attempted 1 numerical and 1 spatial operation at the same time. In contrast to previous research using the same paradigm with a single digit and…

Making spelling instruction effective, fun, practical, and meaningful is a challenge faced by many teachers. Spelling is traditionally taught with prepackaged word lists using a test-practice-test method, which results in little transfer to independent word use. Because spelling is an important component and gauge of literacy skills, students need…

"Everyday memory" is conceptualised as memory within the context of day-to-day life and, despite its functional relevance, has been little studied in individuals with autism spectrum disorders (ASDs). In the first study of its kind, 94 adolescents with an ASD and 55 without an ASD completed measures of everyday memory from the Rivermead…

Several psychophysical and neuropsychological investigations have suggested that the mental representation of numbers takes the form of a number line along which magnitude is positioned in ascending order according to our reading habits. A longstanding debate is whether this spatial frame is triggered automatically as intrinsic part of the number…

In three experiments, we investigated the role of automatic and controlled inhibitory retrieval processes in true and false memory development in children and adults. Experiment 1 incorporated a directed forgetting task to examine controlled retrieval inhibition. Experiments 2 and 3 used a part-set cue and retrieval practice task to examine…

Although signed and speech-based languages have a similar internal organization of verbal short-term memory, sign span is lower than word span. We investigated whether this is due to the fact that signs are not suited for serial recall, as proposed by Bavelier, Newport, Hall, Supalla, and Boutla (2008. Ordered short-term memory differs in signers…

Individuals with autism spectrum disorders (ASD) often exhibit impaired executive function (EF) performance, including difficulty with working memory (WM), in particular. While research has documented the existence of these deficits, surprisingly little research exists that evaluates potential treatment strategies for improving EF or WM. One…

The aim of the present study was to investigate the contribution of working memory and verbal ability (measured by vocabulary) to mathematical skills in children. A sample of 206 seven- and eight-year-olds was administered tests of these cognitive skills. A different pattern emerged that was dependent on both the memory task and the math skill. In…

In this study, 2.5-, 3-, and 4-year-olds (N=108) participated in a novel noun generalization task in which background context was manipulated. During the learning phase of each trial, children were presented with exemplars in one or multiple background contexts. At the test, children were asked to generalize to a novel exemplar in either the same…

The present study examined the memory performance and cortical connectivity of children with ASD, and investigated whether the memory deficits exhibited by these children were associated with the cortical connectivity. Twenty-one children with ASD and 21 children with normal development (NC), aged 5-14 years, participated in the study. Each child…

The Kwangju Democratic Uprising, variously referred to as the Kwangju democratization movement, the Kwangju people's uprising, 5.18, and 5.18 Democratic uprising, is considered a pivotal moment in Korean history. Once framed as a communist disturbance by the ruling military regime, the uprising served a central role in Korea's transition from…

Appropriacy is the paramount consideration of such an inherently polite speech act as thanking in its use. Traditional study of thanking focuses more on the quantitative investigation of its diverse forms and functions than on interpretation of the process in which it is used appropriately and adequately or not among English native or nonnative…

Despite the clear long-term benefits of spaced practice, students and teachers often choose massed practice. Whether learners actually fail to appreciate the benefits of spacing is, however, open to question. Early studies (e.g., Zechmeister & Shaughnessy, 1980) found that participants' judgments of learning were higher after massed than after…
