Fluid reasoning (Gf) performance and response generation speed

During the past few months this blogmaster has provided a number of empirically-based insights regarding individual differences in fluid reasoning (Gf) performance.

Below is yet another potentialy usefull Gf interpretation tidbit.

Verguts, T. & De Boeck, P. (2000). Generation Speed in Raven's Progressive Matrices Test. Intelligence, 27(4), 329-345.

• Performance on fluid reasoning (Gf) tests (e.g., Ravens Progressive Matrices-RPM) may be enhanced by the speed/fluency by which individuals identify rules that govern Gf test items. When faced with fluid reasoning tasks, individuals are viewed to have, at their disposal, a pool or distribution of rules from which to select. The fluency by which an individual “samples” or generates rules (response generation speed) was statistically linked to Gf performance in Verguts and De Boeck’s (2000) study in a sample of 127 undergraduate students.

• This finding is not new. As early as 1898 (Thorndike) noted that in order to generate correct responses to problems, an individual must first generate a number of possibilities, retain them, and then implement the correct possibility/rule. Verbal response fluency has been studied extensively (see Carroll, 1993 for an overview) while Gf-related fluency has not.

• Verguts and DeBoeck (2000) suggest that “If…rules are compared with balls in an urn, this means that people sample balls from an urn. Individual differences in the generation process can be thought of as sampling from different urns (qualitative differences) or at different rate (quantitative differences)” (p.330).

• These investigators demonstrated that response or rule generation speed was correlated with Gf performance (viz., RPM test performance), particularly on items/tasks where discovering the rule(s) is more challenging. However, speed of rule generation should be considered a necessary, but not sufficient condition, for optimal Gf performance. According to these investigators, other variables that may influence rule generation fluency/speed may include individual differences in (a) the quality of rules sampled and (b) the accuracy of applying the generated results (which may be related to working memory efficiency).

Serendipity - recommended book

I recently read Merton ("On the shoulders of giants") and Barber's (2004) The travels and adventures of serendipity. Not an easy read, but a very insightful book that deals with the origins of the word "serendipity"......something that is often present in significant scientific discovers. Below is one of the many quotes I exctracted from the book.

I recommend this book to blogsters who have a historical interest in the development of ideas, words, and "happy accidents" in scientific discovers.

• "Many a scientific adventurer sails the uncharted seas and sets his course for a certain objectives only to find unknown land and unsuspected ports in strange parts. To reach such harbors, he must ship and sail, do and dare; he must quest and question. These chance discoveries are called “accidental” but there is nothing fortuitous about them, for laggards drift by a haven that may be a heaven. They pass by ports of opportunity. Only the determined sailor, who is not afraid to seek, to work, to try, who is inquisitive and alert to find, will come back to his home port with discovery in his cargo" (p.177)

On vacation - don't abandon the blog !

Don't abandon the IQ blog? I'm going on vacation and return on June 26th.

If the spirit moves me and I have any bright ideas while taking a break, I might make some posts. But if you do not hear from this blog, don't fret, I shall return and will commence with my semi-regular posts.

Race, IQ and genetics - Rushton posts the articles

Thanks to a blogster comment, I'm now aware that Dr. Rushton has posted links to all the articles mentioned in my prior "Race, IQ and genetics" post. These can be viewed at his webpage.

Race, IQ and genetics - back on the scholarly radar screen

“Throughout the history of psychology, no question has been so persistent or so resistant to resolution as that of the relative roles of nature and nurture in causing individual and group differences in cognitive ability (Degler, 1991; Loehlin, Lindzey, & Spuhler, 1975)” (Rushton & Jensen, 2005)

To say the least, the above is no understatement.

Probably no contemporary research article has stirred such contentious debate as did Arthur Jensen’s 1969 article in the Harvard Educational Review titled “How Much Can We Boost IQ and School Achievement?” In this historical and controversial article, Jensen concluded that (Rushton & Jensen, 2005):

• IQ tests measure socially relevant general ability
• Individual differences in IQ have a high heritability, at least for the White populations of the United States and Europe
• Compensatory educational programs have proved generally ineffective in raising the IQs or school achievement of individuals or groups
• Because social mobility is linked to ability, social class differences in IQ probably have an appreciable genetic component; and tentatively, but most controversially
• The mean Black–White group difference in IQ probably has some genetic component.

Any psychologist who has treaded on the topic of race, genetics and intelligence has found it a literal mind field

The most recent skirmish regarding this controversial topic was sparked by Herrnstein and Murray’s (1994) The Bell Curve. The Bell Curve generated countless journal articles and books, including an article generated by a special 11-person Task Force (Neisser et al., 1996) of the American Psychological Association (APA).

Fast forward to today.

The APA journal Psychology, Public Policy and Law has again revisited the race/IQ/genetics issue in a series of articles anchored in a lead article by Rushton and Jensen. The lead article is followed by a series of responses by major players in the field. Listed below are the titles and abstracts of the articles in this special issue.

Let me set one thing straight. As the dictator of this blog, I’m only presenting this information on an FYI basis. I do not endorse, either implicitly or explicitly, the position of any of the proponents in this debate. I have not studied the research literature and/or related publications (which are extensive) to the point where I feel I can render any reasonable judgment regarding this contentious topic. I am at the novice end of the race/IQ/genetics research and theory novice/expert continuum. The purpose of this post is to alert serious students and scholars in the field of applied intelligence testing of a publicaton that will likely become a frequently cited source regarding the contentious topic of race, intelligence and genetics.

I will only offer but one opinion.

Regardless of one’s conclusions/beliefs regarding this issue, I found the lead Rushton and Jensen article to be the most succinct, lucid and well-organized synthesis of the historical and contemporary research in this domain. The framework provided by Rushton and Jensen is an excellent organizational heuristic for integrating the vast literature in this domain. The organizational framework provided by Rushton and Jensen is worth the reading……regardless of one’s degree of agreement with their research and conclusions.

I recommend that faculty members who cover the IQ/race/genetics topic in their intelligence theory and/or assessment courses use this special journal issue as a core reading. I would also recommend that all scholars and applied practitioners, who study and/or engage in applied intelligence testing, seriously consider purchasing a copy of this journal issue for reading and reference.

Below are the respective articles and abstracts.


Rushton, J. P., & Jensen, A. R. (2005). Thirty years of research on race differences in cognitive ability. Psychology Public Policy and Law, 11(2), 235-294.

• The culture-only (0% genetic–100% environmental) and the hereditarian (50% genetic–50% environmental) models of the causes of mean Black–White differences in cognitive ability are compared and contrasted across 10 categories of evidence: the worldwide distribution of test scores, g factor of mental ability, heritability, brain size and cognitive ability, transracial adoption, racial admixture, regression, related life-history traits, human origins research, and hypothesized environmental variables. The new evidence reviewed here points to some genetic component in Black–White differences in mean IQ. The implication for public policy is that the discrimination model (i.e., Black–White differences in socially valued outcomes will be equal barring discrimination) must be tempered by a distributional model (i.e., Black–White outcomes reflect underlying group characteristics).

Sternberg, R. J. (2005). There are no public-policy implications - A reply to Rushton and Jensen (2005). Psychology Public Policy and Law, 11(2), 295-301.

• J. P. Rushton and A. R. Jensen (2005) purport to show public-policy implications arising from their analysis of alleged genetic bases for group mean differences in IQ. This article argues that none of these implications in fact follow from any of the data they present. The risk in work such as this is that public-policy implications may come to be ideologically driven rather than data driven, and to drive the research rather than be driven by the

Nisbett, R. E. (2005). Heredity, environment, and race differences in IQ - A commentary on Rushton and Jensen (2005). Psychology Public Policy and Law, 11(2), 302-310.

• J. P. Rushton and A. R. Jensen (2005) ignore or misinterpret most of the evidence of greatest relevance to the question of heritability of the Black–White IQ gap. A dispassionate reading of the evidence on the association of IQ with degree of European ancestry for members of Black populations, convergence of Black and White IQ in recent years, alterability of Black IQ by intervention programs, and adoption studies lend no support to a hereditarian interpretation of the Black–White IQ gap. On the contrary, the evidence most relevant to the question indicates that the genetic contribution to the Black–White IQ gap is nil.

Suzuki, L., & Aronson, J. (2005). The cultural malleability of intelligence and its impact on the racial/ethnic hierarchy. Psychology Public Policy and Law, 11(2), 320-327.

• This commentary highlights previous literature focusing on cultural and environmental explanations for the racial/ethnic group hierarchy of intelligence. Assumptions underlying definitions of intelligence, heritability/genetics, culture, and race are noted. Historical, contextual, and testing issues are clarified. Specific attention is given to studies supporting stereotype threat, effects of mediated learning experiences, and relative functionalism. Current test development practices are critiqued with respect to methods of validation and item development. Implications of the genetic vs. culture-only arguments are discussed with respect to the malleability of IQ.

Gottfredson, L. S. (2005). What if the hereditarian hypothesis is true? Psychology Public Policy and Law, 11(2), 311-319.

• J. P. Rushton and A. R. Jensen (2005) review 10 bodies of evidence to support their argument that the long-standing, worldwide Black–White average differences in cognitive ability are more plausibly explained by their hereditarian (50% genetic causation) theory than by culture-only (0% genetic causation) theory. This commentary evaluates the relevance of their evidence, the overall strength of their case, the implications they draw for public policy, and the suggestion by some scholars that the nation is best served by telling benevolent lies about race and intelligence.

Rushton, J. P., & Jensen, A. R. (2005). Wanted: More race realism, less moralistic fallacy. Psychology Public Policy and Law, 11(2), 328-336.

• Despite repeated claims to the contrary, there has been no narrowing of the 15- to 18-point average IQ difference between Blacks and Whites (1.1 standard deviations); the differences are as large today as they were when first measured nearly 100 years ago. They, and the concomitant difference in standard of living, level of education, and related phenomena, lie in factors that are largely heritable, not cultural. The IQ differences are attributable to differences in brain size more than to racism, stereotype threat, item selection on tests, and all the other suggestions given by the commentators. It is time to meet reality. It is time to stop committing the “moralistic fallacy” that good science must conform to approved outcomes.

On the road again - I shall return

I'm traveling and won't be doing any heavy duty posting until I return late this Thursday.

Stay tunned.....I often do some of my most prodcutive thinking while flying and/or find the time to skim articles that turn into posts.

I shall return!

Journal awareness - Autism spectrum disorder articles

During my weekly review of the social/behavioral science publications listed in the most recent Current Contents index, I noticed two journals (that most folks may not subscribe to---but might want to become aware of) recently devoted their respective issues to autism spectrum disorders. The journals are Developmental Neuropsychology and the Journal of Autism and Developmental Disorders.

Below are the full reference citations from both issues.

I hope that this posting will be the first in a series of semi-regular postings (nothing is regular on this blog) of the contents of select issues of select journals. The goal will be to increase the awareness of the blog readers of sources of information that is available "out there."

Reliable change score software utility

Thanks to Paul Barrett for his recent FYI post about useful software utilities available from Prof. Grant Devilly (Swinburne University [Australia] Centre For Neuropsychology). Avaiable for FREE are the following utilities.

• Effect Size Generator
• Reliable Change Generator
• Random Number Generator
• Odds-Ratio Generator

A link to the output from the Reliable Change Generator is provided above. It looks promising. Below is an excerpt from the web page:

• The Reliable Change Generator was developed to help clinicians, researchers and students to assess whether any change apparent in a client (or anything/one for that matter) isn't just an artefact of measurement. This computer programme was developed to reduce the time it takes to assess reliable change and facilitate the increased use of this statistic in practice and research.
• You can save files, open saved files and even generate a printed one page summary report to keep in your records.
• This was developed following my experiences in teaching university psychology and medical students (many of whom hate statistics with a vengeance) and reading research papers where the authors have made some rather large leaps of faith in whether people "improved" or "worsened" over time. If I can give one piece of advice before you embark on measuring reliable change it is this: As with this programme, statistics are tools – not the end product.

Four Groups Blog - Psychology and Psychometrics

Another interesting blog intersected with IQs corner this morning. Four Groups, which specializes in Human Capital Management around a tool called 4G, has a section where they post information regarding Psychology and Psychometrics.

I'm adding them to my links, with all appropriate caveats (blog readers need to evaluate and judge for themselves).

The blogosphere is growing with psychometric related posts.

Neuropsychologist Brain Blog

This evevning I stumbled on a potentially interesting blog by a consulting neuropsycholgoist called the Brain Blog. Check it out. Blogsters may find it of interest.

Quote to note - Bohr on paradox and progress

"How wonderful that we have met with a paradox. Now we have some hope of making progress"
