On the road again until Aug 1....blogging lite.


I'm on the road again.  I leave Saturday and will be out of the country until I return Aug 1.  

I don't expect much time to blog...except for possible "push" type FYI posts re: content posted at other blogs.....or...mobile blogging (check out the link.....it is very cool...but, of course, I tend to be a tech nerd)......with pictures of activities, people, etc. as I travel.

Of course, I often find flying time and time spent in airports productive for reading...so I may do some blogging...just can't make any promises.  I shall return.

Cattell-Horn-Cattell (CHC) Intelligence Theory Timeline Project

I've been busy taking information from my Cattell-Horn-Carroll CHC (Gf-Gc) Theory:  Past, Present & Future book chapter (in Flanagan & Harrison, 2005 CIA book) and putting it together in a piece of professional timeline software (Timeline Maker).  The software is "way cool" as it allows me to embed hyperlinks to files, images, web pages, etc.  Then, I can use the software, when making presentations, and bring events in one-at-a-time.  AND, at each event there are icons that serve as menus to files, images, etc. that I can "bring up" for viewing and discussion.  I've been embedding the timeline with all kinds of historical images, original classic articles (e.g., Spearman, Thurstone, Cattell, etc.) as well as more recent CHC-related articles.  The idea is for a timeline-based working and breathing educational tool....a timeline-based book chapter if you please.

At this point in time the software allows me to output a web page....but the icon-based hyperlinks don't work (darn).  There is a possible "work around" I'm exploring (which would require a person to download a huge zip file and use the free Timeline Maker Preview program), which would allow people to have all the material on their HD for viewing--but I'm not ready to make that available just yet.

So....for now....you can view the completed Evolution of CHC Intelligence Theory and Assessment web page (sorry..it only is viewable when using Internet Explorer.  I use Mozilla as my browsser and it won't view.....%%$$#$$##).  You will see the various icons that are not active.

Also, I've exported the timeline and put it together with the "notes" from each event...a combined web image/table document.  This is a PDF file that can be downloaded by clicking here.  I added a small number of the embedded images that are available from the working clickable version to the end of the document....just the basics.

Feedback would be appreciated.  The long-term goal is to find a way to make this accessible on-line to others (free) for education and training purposes.  My intent is to add new material and update it on a regular basis.

Stay tuned to this blog for updates...or, subscribe to the CHC listserv for upates re: the projet.

John Horn's (1965) doctoral dissertation test of Cattell's Gf-Gc theory


John Horn's Gf-Gc dissertation available for viewing.

I'm working on a visual-graphic and tex
t-based summary and extension of my previously published "CHC Theory: Past, Present and Future" book chapter...so it can be displayed on the web, and more importantly, can serve as a presentation for instructional/historical purposes. When done I will be giving this material away to those that are interested.

In the process I'm trying to embed hyperlinks to classic articles that will give readers the chance to view and read many of the seminal works that have led us to contemporary CHC theory and intellectual assessment.

Today I'm posting a real gem I found in the process of completing this project. A PDF copy of John Horn's original dissertation (1965). According to Carroll (1993), this was the first real empirical test of Cattell's Gf-Gc theory.

You are forewarned. The file is very large...17+MB. I suggest you don't try download or view from a land phone line or wifi.

Applied Psych Test Design Part G: Psychometric/technical statistical analysis: External

The seventh  in the series Art and Science of Applied Test Development is now available.

The seventh module (Part G:  Psychometric/technical statistical analysis:  External) is now posted and is accessible via SlideShare.

In addition, I've made some new edits and additions  to prior presentations (Part A-F)....so if you've viewed the prior modules you may want to revisit them again.

This is the seventh in a series of PPT modules explicating the development of psychological tests in the domain of cognitive ability using contemporary methods (e.g., theory-driven test specification; IRT-Rasch scaling; etc.). The presentations are intended to be conceptual and not statistical in nature. Feedback is appreciated.

This project can be tracked on the left-side pane of the blog under the heading of Applied Test Development Test Development Series.

The first module (Part A: Planning, development frameworks & domain/test specification blueprints) was posted previously and is accessible via SlideShare.

The second module (Part B: Test and item development) was posted previously and is accessible via SlideShare.

The third module (Part C--Use of Rasch scaling technology) was posted previously and is accessible via Slideshare.

The fourth module (Part D--Develop norm [standardization] plan) was posted previously and is accessible via Slideshare.

The fifth module (Part E--Calcuate norms and derived scores) was posted previously and is accessible via Slideshare.

The sixth module (Part F--Psychometric/technical statistical analysis: Internal) was posted previously and is accessible via Slideshare.

You are STRONGLY encouraged to view them in order as concepts, graphic representation of concepts and ideas, etc., build on each other from start to finish.

That's it for now.  I will likely be revising and adding more material in the future---but this is the "basic" set of materials for now.

WJ III CHC cluster g an specificity characteristics: Floyd et al. (2009) published

The following article, which was previously previewed in an earlier post, has now been published. Check the prior post for links to supplementary tables mentioned in the article. [Conflict of interest disclosure - I am a co-author of the WJ III, which was the focus of this publication]
  • Floyd, R., McGrew, K., Barry, A., Rafael, F & Rogers, J. (2009) General and Specific Effects on Cattell–Horn–Carroll Broad Ability Composites: Analysis of the Woodcock–Johnson III Normative Update CHC Factor Clusters Across Development. School Psychology Review, 38(2), 249-265
Abstract
Many school psychologists focus their interpretation on composite scores from intelligence test batteries designed to measure the broad abilities from the Cattell-Hom-Carroll theory. The purpose of this study was to investigate the general factor loadings and specificity of the broad ability composite scores from one such intelligence test battery, the Woodcock-Johnson Hm Tests of Cognitive Abilities Normative Update (Woodcock, McGrew, Schrank, & Mather, 2007). Results from samples beginning at age 4 and continuing through age 60 indicate that Comprehension-Knowledge, Long-Term Retrieval, and Fluid Reasoning appear to be primarily measures of the general factor at many ages. In contrast, Visual-Spatial Thinking, Auditory Processing, and Processing Speed appear to be primarily measures of specific abilities at most ages. We offer suggestions for considering both the general factor and specific abilities when interpreting Cattell- Horn-Carroll broad ability composite scores.

Dear Cognitive Neuroscientist,

Cognitive Neuroscience - Now Accepting Submissions

Now accepting submissions for a 2010 launch, and edited by Jamie Ward cover of journal(University of Sussex, UK), Cognitive Neuroscience aims to publish high quality empirical and theoretical papers on any topic in the field of cognitive neuroscience.

What is different about Cognitive Neuroscience?

Would you like a publisher to promise online publication of your research within 6 weeks of acceptance? Would you like to avoid hefty charges for essential colour in the printed edition? Do you think there is a need for more short empirical reports together with published discussion (rather than straight reviews) of hot topics?

If so, Cognitive Neuroscience should be the journal of choice for you. This unique blend of features sets it apart from existing publications and we hope it will become a focal point for research and discussion in the field.

The journal fills an important niche in the market by publishing shorter papers (up to 4000 words) and longer discussion papers (up to 8000 words) with peer commentaries alongside.

With fast reviewing and rapid online publication (within 6 weeks of acceptance), the journal will become an essential resource for researchers in fields including, but not limited to: perception, attention, memory, language, action, decision-making, emotions, and social cognition.

Submit your paper through the journal's dedicated submissions website: http://mc.manuscriptcentral.com/pcns

For more information on how to submit or subscribe, visit the journal's website: www.psypress.com/cognitiveneuroscience

Differentiation of cognitive abilites across the lifespan: WJ III norm analysis "in press"

The following manuscript, which analyzed the WJ III norm data [conflict of interest--I'm a coauthor of the WJ III), has been accepted for publication in the journal Developmental Psychology

Differentiation of Cognitive Abilities across the Lifespan. Elliot M. Tucker-Drob, Department of Psychology University of Virginia Charlottesville, V.A.

Abstract
Existing representations of cognitive ability structure are exclusively based on linear patterns of interrelations. However, a number of developmental and cognitive theories predict that abilities are differentially related across ages (age differentiation-dedifferentiation) and across levels of functioning (ability differentiation). Nonlinear factor analytic models were applied to multivariate cognitive ability data from 6,273 individuals, ages 4 to 101 years, who were selected to be nationally representative of the United States population. Results consistently supported ability differentiation, but were less clear with respect to age differentiation-dedifferentiation. Little evidence for age modification of ability differentiation was found. These findings are particularly informative about the nature of individual differences in cognition, and the developmental course of cognitive ability level and structure.

Author Summary
In summary, nonlinear factor analytic models were applied to carefully scaled data on seven well-established cognitive abilities measured in a large nationally representative lifespan sample of individuals. Consistent with the ability differentiation hypothesis, results indicated that a general factor accounted for a decreasing amount of (and proportion of) individual differences in the abilities at higher ability levels, suggesting that at higher ability levels more specific cognitive mechanisms may be less constrained and more prominently expressed. However, results were inconsistent with the age differentiation-dedifferentiation hypotheses that the magnitudes of ability relations decrease with childhood age and increase with adult age. There was rather some evidence to suggest that abilities become more related with childhood age, and less related with adult age. It is proposed that future examinations of age differentiation dedifferentiation focus on the multivariate relations among individual differences in rates of longitudinal changes.
