Just looking at the tests & subtests with the largest gains, there doesn't seem to be much correlation between the increase in scores and the working memory demands of the test. Also, I don't know of research suggesting large increases in working memory in the last 30 or 40 years. We still seem to remember about about 7 items. On the other hand, as commented elsewhere, modern technology may offer meaningful "prostheses" for our working memory, allowing us to juggle more information at once by holding it externally on our desktops and smart phones. In a way, this reminds me of the literature suggesting that illiterate cultures have better long-term memory, suggesting that when literacy made long-term memory less necessary, less cognitive space was accorded to it, perhaps freeing the mind for other kinds of activity.

I wonder if "fluid intelligence" inhibits focus and attention.

In general, cognitive training is often deployed in the cognitive rehabilitation post-strokes, traumatic brain injury and a variety of so-called "brain disorders".

However, I am even more interested in how all this thinking and cognitive research applies to atypical brains. My daughter has a very mild case of holoprosencephaly, accompanied by partial agenesis of the corpus callosum. (Basically, the brain is joined in a spot where it should not be and not joined in a place where it should be.)These anomalies can cause a wide range of effects, but hers now at age 20 are mostly related to learning, memory, and higher-level thinking skills, many of which now seem to be lumped together as "executive functioning." I wonder whether the interventions and methods that work to help neurotypical people could apply to a community college student struggling with these physiological conditions.

The evidence we have right now strongly suggests that attention is strictly limited - a zero-sum game. When attention is deployed to one modality - say, in this case, talking on a cell phone - it necessarily extracts a cost on another modality - in this case, the visual task of driving.” More on on the negative effect of phoning while driving (whether or not you are holding the phone with your hand)from Steven Yantis, as quoted in Caroline Latham’s Nov. 11, 2006 post on this blog:

I find myself reversing letters within a word. It is usually only two letters that are switched, but I still find it creepy. I think I am pressing the letters in the right order, but look up to find them in the wrong position. I think this may be a result of information overload, or yuppie disease. What do you think?

A gap of more than a few seconds, if you're on the phone, might mean a dropped call. In person, there is no such worry. Also, someone in the car with you can see if you're changing lanes, making a turn, etc. This means that conversing on the phone has an implicit demand for fluency of response, with the additional drain on cognitive resources that this implies.
