Machine generated alternative text: Educ Y sycnol Kev  DOI 10.1007/s10648-014-9286-y  REVIEW ARTICLE  Reconceptualizing Working Memory  in Educational Research  Barbara Fenesi • Faria Sana • Joseph A. Kim •  David 1. Shore  C) Springer Science+Business Media New York 2014  Abstract In recent years, research from cognitive science has provided a solid theoretical  framework to develop evidence-based interventions in education. In particular, research into  reading, writing, language, mathematics and multimedia learning has been guided by the  application of Baddeley's multicomponent model of working memory. However, an over-  reliance on this single perspective has overlooked the theoretical diversity of contemporary  research into working memory. We review the successes and shortcomings of applying  Baddeley's model in accounting for a range of evidence and draw attention to alternative  models that have been largely ignored within educational research. Specifically, we evaluate  frameworks of working memory provided by Kane, Engle and colleagues (attentional control  model) and Cowan (embedded process model). We conclude that these alternative views can  support a reconceptualization of the contributions of working memory to academic learning  that may not be afforded by interpretations of the prevailing multicomponent model.  Keywords Working memory • Learning • Education • Attention

Research Byte: Strong working memory (WM)--fluid intelligence (Gf) relationship not due to time allowed on both sets of tasks

Very good article that does not support Chuderski's research that had suggested a relationship between time on task (not the same as cognitive processing speed-Gs) and fluid reasoning or working memory. The current study reinforces the very high (but not 1.0) effect size from working memory to Gf. However, how much time an individual (at least for young adults) spends on working memory or fluid tasks does not explain the strong WM--Gf relation. Generalization to children and the elderly cannot be made without further research.

What I find particularly interesting is the authors hypothesis that one possible general mechanism explanation for the WM-->Gf link is temporal based processing of information. This is consistent with the temporal power resolution hypotheses (or temporal g) of Rammsayer and colleagues and a large body of research I have reported at the Brain Clock blog. If you visit that link, pay particular attention to the MindHub Pub2 that presents a three-level hypothesized model for understanding the IM effect. Note that at the lowest neurocognitive and biological level of intelligence research, I have hypothesized that temporal g (and not Jensen's reaction time g) may be one of the key domain-general mechanisms driving critical cognitive abilities, especially working memory and fluid intelligence.

As per the recent four-level reductionistic framework (see brief 10 minute video explanation) I have offered to organize intelligence related research (adapted from Earl Hunt's work), the current study links research at the psychometric, information processing, and neurocognitive and biological (neural efficiency) levels.

Smoking interfers with central executive "control" brain networks

Yet more research indicating the importance of brain network connectivity, this time demonstrating the detrimental effects of smoking on brain network communication, especially with the executive control and default brain networks.  Take away… smoking may impair the brain networks involved in cognitive control and make stopping smoking even more difficult.

I am not sure how I missed this journal being started in 2013.  It looks like an awesome resource for cutting edge research on the brain clock, brain timing, temporal processing, etc.  I will monitor it on a regular basis.  Click here for more information on the journal.
