I found “Understanding Working Memory” to be an interesting read. I did not read much that was greatly surprising to me, unless it was the claim made that working memory and IQ are not necessarily closely correlated. This claim I had not anticipated. I will refer to some statements in the book that I found especially noteworthy.
One such revelation was that working memory increases until we reach our thirties (see page 6). Not surprisingly, working memory is closely correlated with academic performance (p. 7). On page 8, I found the following claim: “IQ is not nearly as reliable as working memory in predicting grades….” I had wondered whether working memory could be improved significantly. I found this on page 11: “The good news is that we can change their grades by changing their working memory…”
Something that was unexpected for me was the following claim (p. 115): “In contrast, studies have shown that visual-spatial working memory is not affected by generalized or performance anxiety….” Here’s a reaffirmation that working memory can be improved (p. 135): “…However, exciting cutting-edge research suggests that we can train our brain and improve working memory.”
Since it is probably close to axiomatic that genetic endowments are definite factors in regard to one’s levels of working memory, it seems quite definite that genes would constrain how much improvement could be made in one’s working memory capacity. I’m not aware that the book specifically addresses that issue.
This particular book on working memory is quite clearly mostly directed at teachers and parents of school-age children. I had not realized that when I bought the book, but is not a book especially directed at helping the general reader develop strategies for improving one’s working memory. My own expectations about working memory are to the effect that general intelligence (usually correlated fairly much with IQ) is ordinarily fairly significantly correlated with working memory, although I don’t think the book specifically addresses that matter. This book addresses a number of handicaps that are strongly associated with working memory problems, including ADHD, Dyscalculia (math difficulties), Autism, and Anxiety disorders. I can imagine that a book such as this could be greatly beneficial to elementary and high school teachers – especially those who are specializing in supporting students with learning handicaps.
Overall, this was quite a pleasing book for me to read.
