CHC and reading research synthesis project update
The CHC & Reading research synthesis project has been updated (click here for original post and description). Aside from some minor spelling edits, the major changes are a number of significant additions:
- Inclusion of my own ongoing CHC-achievement correlates meta-analysis project results
- Inclusion of other non-CHC organized research synthesis article results in the synthesis (e.g., Shaywitz et al., 2008 Annual Review of Psychology article)
- Links to on-line Power Point presentations from NASP 2008 that provide a context and summary of the results in the larger synthesis "big picture."
- A grand summary table (for those who prefer a linear/tabular summary versus the Gv-oriented clickable Mind Map navigation of the current page).
Did Spearman abandon g? Guest post by Ruben Lopez
The following is a guest post by Ruben Lopez, school psychologist with the Moreno Valley Unified School District, CA and member of the IQs Corner Virtual Community of Scholars.
Ruben reviewed the following article and has provided his comments below.
After his retirement and late in life at age 68, what did Charles E. Spearman, discoverer of the general factor of human intelligence (symbolized as g), really think about general factor g? A recent article in the journal History of Psychology (complete citation above) addresses this question and concludes that Spearman’s long-standing adversaries Godfrey Thomson and Edward Thorndike proposed an incipient version of the CHC broad factors known as fluid (Gf) and crystallized (Gc). If Thomson and Thorndike indeed proposed an incipient non-hierarchical Gf-Gc versus Spearman’s hierarchical g, they began a debate which would continue more than 70 years later between CHC luminaries John Carroll (in support of hierarchical g) against John Horn (in support of non-hierarchical Gf-Gc)—a debate they waged until fairly recently to the end of both of their lives.
In their article, Deary, Lawn, and Bartholomew analyze word for word transcriptions of the contributions Spearman, Thomson, and Thorndike made to the theory and practice of testing intelligence at three meetings in 1931, 1935, and 1938 to which Spearman had been invited by Thorndike. Yet Deary, et al. report that Thorndike and Thomson found their interaction with Spearman to be negative and Spearman felt the same. Moreover, it seems to me that Deary, et al. clearly favored Thomson and Thorndike over Spearman’s contributions and personal style. Deary, et al., for example, describe Thomson as practical and winning, while Spearman in contrast is described as mechanically theoretical and a “contrarian”, waiting only to challenge and correct the theoretical views of the other participants.
Deary, et al. cite statements by Spearman that appear to indicate that he was uncertain or even disbelieved that g exists beyond being nothing more than a statistical phenomenon, as many anti-g proponents wish to communicate when they say that Spearman believed that g was just a “positive manifold.” Deary, et al., for example, suggest that supporters of g should know that at these meetings Spearman said about g, “There is no such thing, but only a general factor in intelligence.” (p. 126)
Yet at the same meeting Spearman said, “This than is what the G term means, a score-factor and nothing more. But this meaning is sufficient to render the term well defined so that the underlying thing is susceptible to scientific investigation; we can proceed to find out facts about this score-factor, or G. We can ascertain the kind of mental operations in which it plays a dominant part as compared with the other or specific factor.” (p. 126) This says to me that Spearman as an objective researcher admitted that g was at least a psychometric fact but at the time was a phenomenon that was not understood in psychological or biological terms.
Therefore, this article convinced me that even as an old man, likely battle worn by younger adversaries like Thorndike and Thomson, Spearman did not appear to have abandoned g. In fact, one year after the last meeting with Spearmen at a symposium of the British Psychological Society in 1939, Godfrey Thomson is quoted in the article as saying, “I myself lean at the moment more toward Spearman’s g and his later group factors than I do to Thurstone’s….” (p. 129) Also, 69 years ago, Thomson conceded at the symposium, “Surely the real defense of g is simply that it has proved useful.” (p. 129)

Disseration Dish: God and IQ
I just ran across this new unpublished doctoral dissertation. I only have read the abstract so I have no basis on which to comment on the methodology, size of the "marginal" relationship between Glr and "Awareness of God", etc. This is just an FYI post. I wish I did have access to the entire dissertation as I'd be interested in the literature review and hypothesis about the Glr-spirituality link.

Cognitive deficits and spiritual development: The relationships between cognitive deficits and spiritual development by Thomas, Charles Nolan, Ph.D., Liberty University, 2008, 117 pages; AAT 3297567
Abstract (Summary)
- An individual's spirituality is shaped and supported by his or her cognitive capacities. The purpose of this study was to investigate the relationship between various cognitive deficits and the spiritual development in individuals who qualified for special education under the category of Specific Learning Disability. Participants were randomly selected through systematic sampling of students and former students of Kellyville Public School who met the criteria. The cognitive deficits were measured by the Woodcock-Johnson III Tests of Cognitive Abilities (2001) or the Woodcock-Johnson Psycho-Educational Battery-R (1989), and spiritual development was measured by the Spiritual Assessment Inventory (2002). The results of this study indicate that there is a marginal correlation between Long-Term Retrieval and Awareness of God.

Dissertation Dish: WJ III and ADHD and poor reading
Two new unpublished dissertations located that used Woodcock-Johnson III (WJ III) measures (conflict of interest disclosure - I'm a coauthor of the WJ III) to investigate the relations between (a) Gs and poor reading and (b) WJ III clinical clusters and tests and ADHD.
In a sample of 26 ADHD (and 26 controls), Bray (2004) reported that the WJ III clinical clusters, based on discriminative function analysis, correctly classified 72.4% of the ADHD subjects. From a pool of 11 WJ III tests, correct classification was 87.2 %. The most highly discriminating tests were Auditory Attention, Auditory Work Memory and Rapid Picture Naming. Interesting.
Urso (2008) reports strong relations between processing speed (Gs) and poor reading performance. Although the results are interesting, the real value of this dissertation (IMHO) is the excellent literature review of the processing speed (Gs/Gt) literature, particularly as it relates to reading disabilities.
Hopefully the authors of these dissertations will work them into manuscripts to be submitted for journal publication.Technorati Tags: psychology, eduational psychology, school psychology, neuropsychology, ADHD, dyslexia, reading disabilities, LD, learning disabilities, WJ III, Woodcock Johnson, CHC, Cattell-Hon-Carroll, IQs Corner

IQ Research Bytes # 3: Working memory in recent Intelligence issues
I give up. I can't keep up with the sheer mass of working-memory research articles I acquire, with the full intention of reading and make blog comment posts. There is simply tooooooo much being published. My prior post today (Working memory research is hot) provides links to all IQ's Corner working memory posts and a fresh working memory reference bibliography.
Below are working-memory articles (reference and abstracts only) that were either in the latest issue of Intelligence or are "in press" in the journal. If someone wants to take the time to read one or more of these articles and produce a guest Virtual Scholars blog post, I'd be willing to provide the volunteers with access to the articles off-line. Contact me via email if you are interested in helping keep readers abreast of recent research in this area.

Contact me via email if you are interested in helping keep readers abreast of recent research in this area.
Vock, M & Holling, H (2008). The measurement of visuo–spatial and verbal–numerical workingmemory: Development of IRT-based scales. Intelligence, 36, 161–182
- The objective of this study is to explore the potential for developing IRT-based working memory scales for assessing specific working memory components in children (8–13 years). These working memory scales should measure cognitive abilities reliably in the upper range of ability distribution as well as in the normal range, and provide a much-needed, reliable, and valid test for assessing high intellectual abilities in children. Six computer-assisted working memory tasks were administered to 172 children from regular schools and to 202 children from special schools and other institutions for the gifted. A factor analysis revealed a two-factor structure and the existence of a verbal–numerical and a visuo–spatial working memory scale. Classical item analysis and IRT analysis yielded good psychometric properties for both scales and revealed that the scales are appropriate for measuring high cognitive abilities. Both scales showed substantial and differential power for the explanation of variance in school achievement.
- Meta-analyses are presented of sex differences in (1) the (mental) arithmetic subtest of the Wechsler intelligence tests for children and adolescents (the WISC and WPPSI tests), showing that boys obtained a mean advantage of .11d; (2) the (mental) arithmetic subtest of the Wechsler intelligence tests for adults (the WAIS tests) showing a mean male advantage of .47d; (3) the digit span subtest of the Wechsler intelligence tests for children and adolescents (the WISC and WPPSI tests), showing that girls obtained a mean advantage of .134d; (4) the digit span subtest of the Wechsler intelligence tests for adults (the WAIS tests) show in a male advantage of .116d among adults. These results show that the sex differences on mental arithmetic are not consistent with the sex differences on digit span. It is proposed that the reason for this is that mental arithmetic is a measure of working memory capacity while digit span is a measure of immediate memory capacity. If this is accepted, the results indicate that there is virtually no sex difference in immediate memory capacity (measured by digit span) but a small male advantage among children and a substantial male advantage among adults in working memory capacity (measured by mental arithmetic). The results are further interpreted in terms of Kyllonen's theory that working memory capacity is g. If this is accepted, it follows that males have an advantage in g and that the higher average means obtained by men in IQ tests like the WAIS and the Progressive Matrices is attributable to their advantage in g.
- Working memory and the general factor of intelligence (g) are highly related constructs. However, we still don't know why. Some models support the central role of simple short-term storage, whereas others appeal to executive functions like the control of attention. Nevertheless, the available empirical evidence does not suffice to get an answer, presumably because relevant measures are frequently considered in isolation. To overcome this problem, here we consider concurrently simple short-term storage, mental speed, updating, and the control of attention along with working memory and intelligence measures, across three separate studies. Several diverse measures are administered to a total of 661 participants. The findings are consistent with the view that simple short term storage largely accounts for the relationship between working memory and intelligence. Mental speed, updating, and the control of attention are not consistently related to working memory, and they are not genuinely associated with intelligence once the short-term storage component is removed.
- Investigates the relationship between three factors of working memory (storage and processing, relational integration, and supervision) and four factors of intelligence (reasoning, speed, memory, and creativity) using structural equation models. Relational integration predicted reasoning ability at least as well as the storage-and-processing construct. Supervision, measured as specific switch costs, was not related to intelligence, but general switch costs were moderately correlated to the reasoning factor. The results question the view of working memory as a device for storage and processing, and the executive-attention account of working memory. They are better explained by theories describing working memory as a system for building relational representations through temporary bindings between component representations.
- This study investigated, in children aged 6–13 years, how different components of the working memory (WM) system (short-term storage and executive processes), within both verbal and visuospatial domains, relate to fluid intelligence. We also examined the degree of domain-specificity of the WM components as well as the differentiation of storage and executive components. The short term memory (STM) and WM tasks used allowed us to statistically separate the executive from the storage processes, enabling examination of separate processes in relation to intelligence. Our results demonstrated that all four WM components (verbal- and visuospatial short-term storage and verbal- and visuospatial executive processes) provided significant, independent contributions to intelligence, indicating that, in children, both storage and executive processes of the WM system are relevant to intelligence. Especially intriguing are our findings showing that verbal and visuospatial executive processes independently predicted intelligence, suggesting that, in children, the executive processes may rely on separate resources for the verbal and visuospatial domains.

Abstract
- Even within “an appreciation of the fundamentally social nature of scientific activity” (K. Danziger, 1990, p. 3), it is unusual to read what key scientists actually said to each other, directly or in audience. Here the authors describe, structure, illustrate, and interpret the verbatim statements made by, and a detailed conversation that took place between, Charles Spearman, Godfrey Thomson, and Edward Thorndike within the Carnegie-funded International Examinations Inquiry meetings in 1931, 1935, and 1938. Unusually, there were transcriptions of all comments at these meetings, even of the smallest verbal utterance. The transcriptions offer a novel look at these researchers’ theoretical and practical approaches to intelligence testing and its place in education. Aspects of Thomson’s and Spearman’s personalities are in evidence too, from this unique source. One particular conversation among the three leads to an important new insight about intelligence and intelligence testing. These conversations provide new and complementary information on a trio of leading intelligence researchers whose individual contributions and interactions with each other were seminal in the scientific study of human cognitive abilities.

Working memory, Gf and task switching article
Database: PsycARTICLES
[Journal Article]
Speed and accuracy of accessing information in working memory: An individual differences investigation of focus switching.
Unsworth, Nash; Engle, Randall W.
Journal of Experimental Psychology: Learning, Memory, and Cognition. 2008 May Vol 34(3) 616-630
Abstract
Three experiments examined the nature of individual differences in switching the focus of attention in working memory. Participants performed 3 versions of a continuous counting task that required successive updating and switching between counts. Across all 3 experiments, individual differences in working memory span and fluid intelligence were related to the accuracy of the counts, but not to the time cost associated with switching between counts. The authors suggest that working memory span and fluid intelligence measures partially index the ability to accurately switch information in and out of the focus of attention, but this variation is not related to the speed of switching.

- Are executive functions highly genetic? Check out post at Developing Intelligence for comments on a recent research study.
- Sharp Brains continues to impress above all the rest in documenting and explaining the brain fitness movement. Now they are offering a Brain Fitness Webinar Series. Kudos to SB.
- Self-serving blog plug. Check out post regarding recent genetic research suggestive of a link between autism and mental timing (the IQ Brain Clock)

CHC theory overview article: Recommended resource
I just read what I believe is one of the most concise and up-to-date summaries of contemporary CHC intelligence theory.
The article was just published in the American Annals of the Deaf by Dr. Bryan D. Miller, Associate Professor of Psychology, Gallaudet University. The introduction and review would serve as concise overview for anyone interested in learning about CHC theory. In all honesty, much of the material sounds very familiar....that it was gleaned from Dr. Miller's reading of the major contemporary CHC articles and chapters, including my own CHC Theory: Past, Present and Future. I consider it a compliment when someone extends my work..as well as the work of other contemporary CHC scholars. My only criticism is that greater credit should have been given to Dr. Richard Woodcock for being the primary mover-and-shaker in bringing Gf-Gc/CHC theory over to the field of applied intellectual assessment [see my historical treatment in CHC Theory: Past, Present and Future].
I have no expertise with this particular special population. Of interest to me was Dr. Miller's conclusion, based on a synthesis of research, that cognitive strengths in this population lie primarily in Gf, Glr, and Gv. What excites me most is the infusion of the CHC theory and terminology into another field.
As I've mentioned before (click here and here), the CHC tipping point has arrived as evidence by its infusion in related fields.

WMF Human Cognitive Abilities archive project announcement
I'm pleased to announce, under the auspicious of my Woodcock-Munoz Foundation (WMF) Research Director Position hat (one of the many hats I wear), that the WMF Human Cognitive Abilities Archive Project is now operational! The focus of this project is to make available (for secondary data analysis) the original correlation matrices used by Dr. John "Jack" Carroll in his seminal treatise Human Cognitive Abilities: A Survey of Factor-Analytic Studies (Carroll, 1993).
The WMF HCA archive can be found by clicking here (for Gv-oriented MindMap navigation, here for more traditional web page navigation, and here for a simple outline navigation mode. You can toggle between the three navigation modes via the three options in the upper right hand corner of each modes home page.
As you will see when visiting the site, there is a special WMF HCA announcement (newsletter) listserv that one should join to receive routine updates regarding the posting of new correlation matrices, as well as other project related information. Correlation matrices, as well as copies of the original manuscripts (if they can be located), will be posted as they are processed.

Music, language and intelligence: Book review
The link between music, language and intelligence has intrigued laypersons and scholars for decades. If you want to check out a new book in the area, check out Music, Language and the Brain by A. Patel (2008).
A review of the book was recently published in Nature Neuroscience.
