Non-cognitive abilities finally a target of national assessments


Finally!!!!!!  Noncognitve abilities (aka. conative abilities), which I have been writing about for over 10 years, are finally on the national educational radar screen.  Check out the Model of Academic Competence and Motivation (click here for all MACM labeled posts) and all the "Beyond IQ" posts.

WAIS-IV Canadian/US norm controversy--all articles for readers to review



I previously provided an FYI post on a hot topic in Canada...claims that the new WAIS-IV Canadian norms were flawed.  There are now three articles outlining the different arguments.  The three articles, published in JPA, can be found here, here, and here.

I continue to not comment on this controversy given my obvious conflict of interest as a coauthor of the competing WJ-IV.

Another IQ score Flynn effect meta-analysis

 (click on image to enlarge)

A second massive meta-analysis of the Flynn effect (norm obsolescence) was recently published (Pietschnig & Voraseck, 2015)  The study investigated different Flynn effect ability domain effects (by Gf, Gc, Gv), and other moderating variables.  However, the most important conclusion is that the authors conclude that the 3 IQ points per decade rule-of-thumb appears to be the best estimate of the FE on global IQ scores.  This conclusion is consistent with the Trahan et al. (2014) meta-analysis and the recent AAIDD recommendation.


AAIDD chapters on intellectual functioning and the Flynn effect - overdue post

I just made this post over at the Intellectual Competence and Death Penalty blog and am repeating it here for interested readers.

(Click on image to enlarge)




It has been along time since I've been able to devote time to any of my three professional blogs.  I have been unbelievably busy with travel and professional presentations.  In fact, I have been so busy that I failed to feature two of my own recent Atkin's death penalty related book chapters that appeared in the new AAIDD book "Determining Intellectual Disability in the courts: Focus on capital cases." I have made these two chapters available via the MindHub web portal but do not believe I featured them at this blog (or at IQ's Corner).  One chapter deals with assessment of intellectual functioning issues and the other IQ test norm obsolescence (aka., the Flynn Effect).  The references (with links) are below.
