Controlled attention, working memory and brain clock

Central to my thinking regarding the temporal brain clock is the notion of working memory. A number of models of working memory have been proposed, with the first and most prominent being the working memory (WM) model of Baddeley and Hitch (1974).

Myself....I've been very interested in the controlled executive attention (CEA) model of WM of Engle, Kane, and Conway. For readers who have kept up with this blog, and/or those who have heard me present on the IQ Brain Clock (see on-line viewable PPT slide section of this blog page), it is clear that I believe that there is a strong link between the brain clock's temporal processor and the construct of working memory....esp. the shared link in the dorsolateral prefrontal cortex and the central role that CEA plays in the brain clock, working memory, and temporal processing based timing interventions.

Today I skimmed a very nice and concise explanation/definition of the CEA model of WM. The following was in the introduction of an article by Colflesh and Conway (2007) Psychonomic Bulletin and Review:

  • According to the CEA model of WM "there is a domain-general component of WM responsible for guiding attention as well as domain-specific components responsible for maintenance of task-relevant information. Individuals who score high on tests of working memory capacity (WMC) therefore may do so because of greater controlled attention and/or because of better use of domain-specific skills and strategies to aid maintenance. Engle and colleagues have argued that the domain-general controlled attention ability is related to both higher-level cognition, such as fluid intelligence, reading comprehension, and problem solving, and lower level cognition, such as performance of simple visual and auditory attention tasks that require cognitive control."

Are you auggesting that someone who does well on a WM test (e.g., digit span backwards) may still have poor WM? Interesting!
