Every so often I run across a book or journal article that, in my opinion, resonates with considerable clarity re: something important regarding human intelligence and or understanding learning and or learning disabilities. I'm not sure if these readings, as viewed by others, would be accorded similar value, or if the readings just hit me at a time when I'm trying to "connect the dots"
across the diverse literature that I skim on a routine basis.
I just finished skimming one such article. The article is by David Geary
in Developmental Neuropsychology
(2007, vol 32, p. 471-519; click here to view
). The title of the article is "An evolutionary perspective on learning disabilities in mathematics.
" I try to read anything that David Geary writes as, IMHO, he is one of the top notch intelligence/cognitive scholars of our times, particularly as his research relates to helping us understand an important aspect of school learning--mathematics
I plan (hope) to make a number of posts as I distill the essence of what he has written. The real beauty of this article is that it is a grand synthesis article that puts, in one place, his current synthesis of contemporary research on the development of mathematics and possible causes of math learning disabilities.
At this time I'm just alerting my readers to the article and making it available for viewing. Although some of the evolutionary material may be a bit difficult to digest, and does not have direct application to applied intelligence testing and interventions, the remainder of the article is packed with useful summary statements regarding the potential cognitive mechanisms, underlying neuroanatomy, etc. of mathematical learning.
More to come. But in the meantime, please read and digest on your own pace. I urge readers to take the time to become familiar with this article, as well as other research published by David Geary (a select list is below).
