Brain changes due to reading intervention

Interesting post at DERIC BOWNDS MINDBLOG suggesting, as have other
studies, that reading interventions can produce chants in the brain.

Big River Consulting: Organization consultion

This is a bit off-topic for this blog, but I just had coffee with the folks from Big River Consulting, a MN-based organizational consultation group. I've known the owner/CEO, Dr. Bruce Miles, since my days at St. Cloud State University. A great guy and expert in making organizations work more effectively. He is working on a book at this time. Check them out if your organization needs some assistance with a variety of complex issues (e.g., strategic planning, leadership training, staff hiring, conflict management, etc.)

In press CHC theory overview and HCA project manuscript


I'm pleased to announce that the following manuscript re: CHC (Cattell-Horn-Carroll ) theory and the Human Cognitive Abilities (HCA) project is now "in press" in the journal Intelligence. Readers may be particularly interested in the CHC Theory model figure (Figure 1) which represents the most comprehensive overview of contemporary CHC theory.


McGrew, K. S. (in press). CHC Theory and the Human Cognitive Abilities Project: Standing on the Shoulders of the Giants of Psychometric Intelligence Research. Intelligence.


As per the the Scholary Posting provision of the journals publication agreement, I've made a pre-publication copy of the submitted manuscript available at the HCA Archive web page (it can be found on the "HCA Project Communications and Announcements" branch).

Some CHC specific abilities are important in school learning: Reflections on the g+specific abilities research


[Double click on image to enlarge]


Back in 1997, I, together with Dawn Flanagan, Tim Keith and Mike Vanderwood, published our first g+specific--->achievement article in School Psychology Review. I recently searched high and low for a pdf copy of this article via the usual library sources but came up blank. I finally scanned a copy into a pdf file. A copy of this article can be viewed by clicking here.

Included in that article was the figure to the right (double click to enlarge the figure). I've always liked this figure as it laid out the reasoning why the "just say no" (to intelligence test subtest analysis) research needed to be revisited in light of advances in: (a) theories of intelligence (CHC theory), (b) measurement of intelligence constructs (Gf-Gc or CHC-grounded batteries), and (c) statistical methodology (SEM vs multiple regression). The figure summarizes much of the introductory text in the 1997 article. Frankly, this publication is one of those for which I'm the most proud. Why?

First, the results demonstrated that some specific abilities are important in understanding reading and math achievement above and beyond the effect of g (general intelligence). IMHO this was a very important finding...and led us to argue for the "just say maybe" position (re: interpretation of strength and weakness profiles of cognitive tests---where the S/W measures where composites of at least 2 tests---cluster scores). Even Dr. Dan Reschly, someone typically associated with the anti-IQ movement in school psychology, in a response article in the same special SPR issue, stated (with regard to our 1997 article) :
  • “The arguments were fairly convincing regarding the need to reconsider the specific versus general abilities conclusions. Clearly, some specific abilities appear to have potential for improving individual diagnoses. " (Reschly, 1997, p.238).
Second, this "mother" study lead to a systematic program of g+specific abilities research that continues to suggest that certain broad/narrow CHC abilities are important in understanding reading and math achievement above and beyond the effect of g (general intelligence). A listing of articles that followed can be found by clicking here. Click here if you want to view all g+specific abilities posts that have been made at IQ's Corner. There are now a sufficient number of these studies, that when combined with CHC no-g model multiple regression studies, that I was able to recently complete the formative work on a research synthesis (CHC Cognitive-Achievement Correlates Meta-Analysis Project) of the collective findings (which I will eventually be summarizing in a manuscript). A review of all studies continue to support the "just say maybe" position.

Interestingly, although not dealing with reading and math achievement, a recent article in the prestigious journal Intelligence provided additional support for the g+specific "just say maybe" position. The CHC-organized article by Reeve (2004) demonstrated that specific cognitive abilities are indeed important (above and beyond the effect of g) in understanding and explaining the development of domain-specific knowldge (Gkn). The Reeve article provides an excellent review of the literature and, in many respects, reflects (and extends and augments) the arguments we made in our original 1997 article. I urge those interested in the g+specific abilities debate to carefully read Reeve's literature review...as well as his findings. The Reeve findings are important given the extremely large size of the sample (n = 300,000+ from the famous PROJECT TALENT project)

Finally, I would be remiss if proper credit was not given to the "grandmother" article that first stimulated our (McGrew et al., 1997) initial g+specific abilities project, and which also appeared to play a noticeable role in the Reeve (2004) study. Our original research was started after reading the following article:
  • Gustafsson, J. -E., & Balke, G. (1993). General and specific abilities as predictors of school achievement. Multivariate Behavioral Research, 28, 407–434. (click here to view)
Enough said for now. I believe that a sufficient body of research evidence now exists that demonstrates there is more to understanding acquired knowledge acquisition and school achievement than g (general intelligence). When utilizing an appropriately valid and comprehensive model of intelligence (CHC theory) and appropriately designed and analyzed models, certain specific broad or narrow specific abilities are found to be important...and their effect sizes are not trivial. There is more to understanding school functioning than a simple full scale g-type score.

Of course, if one does not believe in the construct of g (e.g., John Horn's adamant position), then narrow and broad CHC abilities are found to be even more important (as reflected in the non-g CHC organized multiple regression studies integrated in the above mentioned research synthesis). However, that is another post (or series of posts).

Summer blogging, mobile blogging, push mobile blogging, etc.

I need to apologize to my regular readers for not posting much in the way of creative and unique content this summer. I've simply been swamped with summer activities and major projects that are sucking up all my time (blogging done is my spare hobby time). In addition, since getting my iPhone, I've been experimenting with mobile blogging...with all posts coming directly from my little phone. It is a personal blog called Mobile IQ.

One thing folks may have noticed is that I've made more brief and somewhat messy FYI posts to my two major blogs (IQs Corner; the IQ Brain Clock). These posts have also come from my iPhone. Via the use of Mobile Bloglines, I get constant RSS feeds of stories at other interesting blogs. When I see something of interest, it only takes a few taps on my iPhone screen to send an FYI post to my major blog. It is very quick and sweet...actually quite amazing. Unfortunately, the downside is that the URL links come through in their full messy splendor...they are not neatly embedded in the text. But, the instant "push-to-my-major-blogs" speed outweighs the less-than-perfect neatness of regular posts. I could go in later (on my primary computer) and clean everything up....but that defeats the purpose of instant mobile push posts.

Enough idle chatter. I'm hoping to start more regular posts very soon...possibly even toady. Your patience and continued patronage to my blog is much appreciated.

  • GING21: Singer, H. (1965). Validity of the Durrell-Sullivan Reading Capacity Test. Educational & Psychological Measurement, 25, 479-491.
New manuscript: In addition, the following "in press" editorial manuscript (journal of Intelligence) has been added to the HCA project archive:
  • McGrew, K. (in press). CHC Theory and the Human Cognitive Abilities Projects: Standing on the Shoulders of the Giants of Psychometric Intelligence Research. Intelligence.

Request for assistance: The HCA project needs help tracking down copies of old journal articles, dissertations, etc. for a number of datasets being archive. Please visit the "master bibliography/inventory" section of this archive and visit the on-line dataset/reference file. When viewing the on-line working inventory, manuscripts/references featured in the color red are those we are currently having trouble locating. If you have access to either a paper or e-copy of any of the designated "fugitive" documents, and would be willing to provide them to WMF to copy/scan (we would cover the costs), please contact Dr. Kevin McGrew at the email address listed at the site.

Please join the WMF HCA listserv to receive routine email updates regarding the WMF HCA project.
