Research shows neural efficiency of motor-related activity based on learning and expertise in a specific domain (e.g., guitar playing, sharp-shooting or a sport). However, it is unknown whether neural efficiency of motor-related activity, underlying action planning and maintenance, can be modulated by general cognitive ability alone. This study examined whether working memory span can influence...

Using Brinley plots, this meta-analysis provides a quantitative examination of age differences in eight verbal span tasks. The main conclusions are these: (a) there are age differences in all verbal span tasks; (b) the data support the conclusion that working memory span is more age sensitive than short-term memory span; and (c) there is a linear relationship between span of younger adults and ...

The capacity of working memory is limited and is altered in brain disorders including schizophrenia. In rodent working memory tasks, capacity is typically not measured (at least not explicitly). One task that does measure working memory capacity is the odor span task (OST) developed by Dudchenko and colleagues. In separate experiments, the effects of medial prefrontal cortex (mPFC) inactivation...

Short-term memory and working memory are two distinct concepts that have been measured in simple and complex span tasks respectively. A new span task was designed to manipulate a chunking factor while using a procedure similar to simple span tasks. This span task allowed studying the interaction between storage and processing in working memory, when processing is fully dedicated to optimizing s...

Objectives: The purpose of this research was to explore the possible differences in the working memory of monolingual (Persian) and bilingual  (Persian-Baluchi) children. We wanted to examine if there is a statistically significant relationship between working memory and bilingualism. Methods: Four working memory (WM) tests, assessing three WM components, were administered to 140 second...

Results from an experiment with two parts are presented in this paper. In part one, participants listened to sentences containing two, three, four, or five clauses, and were asked questions about the content of the sentences. The results of part one demonstrate that an important unit of representation in sentence memory is the clause, and not some other component of discourse structure. In part...

White matter hyperintensities (WMH) are commonly observed in elderly people and may have the most profound effect on executive functions, including working memory. Surprisingly, the Digit Span backward, a frequently employed working memory task, reveals no association with WMH. In the present study, it was investigated whether more detailed analyses of WMH variables and study sample selection a...

background: this study assessed the relationship between working memory capacity and auditory stream segregation by using the concurrent minimum audible angle in children with a diagnosed auditory processing disorder (apd). methods: the participants in this cross-sectional, comparative study were 20 typically developing children and 15 children with a diagnosed apd (age, 9–11 years) according t...
