“Garden-variety” just means “typical”, and by “armchair speculation” I meant opinions not backed up rigorously and not grounded in the relevant sciences (e.g., cognitive neuroscience, neuropsychology).
I should have left out the “armchair”, since that gives the wrong impression of speculating about things in which one has no experience whatsoever, which is not the case here.
I agree. And it’s too bad—there’s a lot psychology has to say about mental focus and attention, about how high working memory leads to greater focus, etc.
I define it practically: any mental state in which I’m able to score higher than usual playing Dual N-Back. Any more complex definition falling back on ‘being able to suppress unwanted stimulus’ or ‘remembering in short-term or working memory that which is needed’, seems too vague and begging the question for my taste.
Mayhap effectiveness is focus. Two words may denote the same concept, after all. As I said, any other definition seems to be essentially ‘having in one’s mind only that which is wanted’, which is not a definition at all. My scores on DNB are positively correlated with my subjective impressions of focus; it’s good enough for me.
There’s nothing really written for the layman online (which I know of). You can start by googling for topics like ‘latent inhibition’ and research on meditation.
EDIT: in the future, Google will be deleting Groups’ Files. You will want to search around for where the collection has moved to; I keep local copies of the most important ones in my wiki, and I copied all files c. October 2010 to my Dropbox account.
It looks to me like garden-variety armchair speculation and argument from personal anecdote.
can you define garden-variety armchair speculation?

what’s focus for you? Really curious about how you define it :-)

That seems to me a definition of effectiveness, not focus.

Do you have a link to some well-written material on the subject? You’ve piqued my curiosity.

Genuine research papers-wise, you could join http://groups.google.com/group/brain-training to which group’s files I have uploaded ~20 papers on various topics related to working memory and focus.
