The new Cattell-Horn-Carroll (CHC) periodic table of cognitive elements: Build your own

The latest and greatest CHC periodic table of cognitive elements is now available!

I've been meaning to make this post for a long time.  Below are the front and back images of my official CHC periodic table of cognitive elements.  This revision reflects Dr. Joel Schneider and my CHC theory update chapter to be published this fall (I believe next month) in the latest CIA (contemporary intellectual assessment) book.

Some of you may be familiar with the fact that, for the prior version, I had the table professionally printed (one sheet...both sides used) and laminated.  I distributed these during some of my presentations and at conferences.  The response was always positive.  My original plan was to have a new batch professionally printed and laminated and to make them available for a nominal fee via PayPal.  However, I was stalled by the details of having to deal with different state sales taxes, accepting payments, packaging, and mailing.  Instead, I am now providing interested people with the actual JPEG images (click here to download).  You can print your own copy and laminate if you want.  Build your own CHC periodic table of cognitive elements!

A PDF copy of the latest definitions, abstracted from our chapter, can be found here.

Enjoy.

Nature, Nurture, and Human Autonomy with James Flynn - Scott Barry Kaufman

Nature, Nurture, and Human Autonomy with James Flynn - Scott Barry Kaufman

Nature, Nurture, and Human Autonomy with James Flynn

"When you turn your back on reality you lose the ability to manipulate reality. One would think that is self-evident. I didn't go into this to not try to find the truth." — James Flynn*

Today it is an honor to have Dr. James Flynn on the podcast. Dr. Flynn is Professor Emeritus at the University of Otago and recipient of the University's Gold Medal for Distinguished Career Research. In 2007, the International Society for Intelligence Research named him its Distinguished Contributor. His TED talk on cognitive and moral progress has received over 3.5 million visits. His long list of books include Are We Getting Smarter?, What is Intelligence?, Where Have All the Liberals Gone?, Fate and PhilosophyHow to Improve Your Mind, and most recently, Does Your Family Make You Smarter?: Nature, Nurture, and Human Autonomy.

In this episode we cover a wide range of topics relating to intelligence and its determinants, including:

  • Flynn's attempts to clarify intelligence and its causes
  • The g factor, and what gives rise to it
  • The validity of multiple intelligences theory
  • Intergenerational trends (the "Flynn effect") vs. Within-generation trends
  • The "social multiplier" model of intergenerational trends in intelligence
  • Individual multipliers vs. social multipliers
  • The multiple causes of black-white differences in IQ
  • Charley Murray and the meritocracy thesis
  • Transcending the politics of intelligence research
  • The dangers of suppressing ideas and research
  • The 20% wiggle room of autonomy on IQ tests
  • The difference between internal and external environment
  • The impact of having a "family handicap" on SAT scores
  • What we can learn from astronomy about human intelligence
  • Toward a meta-theory of intelligence
  • Toward a more humane society

Twitter Q & A with James Flynn

  1. "Would a 100 IQ person today be a genius if transported to the year 1918? If not, why not." https://twitter.com/robkhenderson/status/1027707019317403650

Flynn: No, they would just be better adapted in their ability to meet educational demands.

  1. "Are you concerned with the growing misuse of genetic causal fallacies in heritability research, and what can be done to make sure that researchers do not assert implications that are not supported by the data? Is this a question of education?" https://twitter.com/NathanH90714587/status/1027690457504002048

Flynn: Whenever I catch them I am disturbed by both bad genetic hypotheses and bad environmental ones.

3. "What has caused the Flynn reversal in Nordic and some other rich countries? Markus Jokela suggested it could be health related." https://twitter.com/mark_ledwich/status/1027685177231695872

Flynn: See this article in Intelligence by myself and Shayer on IQ decline.

  1. "Prof. Flynn has written about the increase in non-verbal reasoning on IQ tests that is attributed to the exposure to analytical/sequential/logical reasoning through technology. What should we do, then, to increase the verbal side of our reasoning, or have we reached the peak?" https://twitter.com/jakub_ferenc/status/1027682377169076224

Flynn: Read good literature and stand out against the trend to read less and less (see Flynn, The Torchlight List  and The New Torchlight List.

5. "Could the Flynn effect be based at least partially on a trade off, meaning that with change in culture promoting development of skills associated with higher IQ scores, this rise is at a cost of eg working memory?" https://twitter.com/Kapusta2365/status/1027689783219380225

Flynn: I don't think there is a downward trend in working memory – see Does Your Family Make You Smarter?

6. "Do the intelligence gains the Flynn effect reveals show an in increase in the g factor?" https://twitter.com/DabneyPierce/status/1027684042022432768

Flynn: No – see "Reflection about intelligence over 40 years" just posted on the net.

7. "What do you make of American SAT/ACT trends, that is the Asian scores increases and the Native-American scores declines?" https://twitter.com/UnsilencedSci/status/1027682180737130497

Flynn: Sorry I have only looked at black and white.

8. "Does you ever think there will come a time when rational, non-bigoted people can publicly discuss race and gender topics relating to your research?" https://twitter.com/AFIChai/status/1027732647349547009

Flynn: Well I hope so – but there is no trend in that direction.

Beyond IQ: Mining the “no-mans-land” between Intelligence and IQ: Journal of Intelligence special issue

I am pleased to see the Journal of Intelligence addressing the integration of non-cognitive variables (personality; self-beliefs; motivational constructs; often called the “no-mans land” between intelligence and personality— I believe this catchy phrase was first used by Stankov) with intellectual constructs to better understanding human performance. I have had a long-standing interest in such comprehensive models as reflected by my articulation of the Model of Academic Competence and Motivation (MACM) and repeated posting of “beyond IQ” information at my blogs.

Joel Schneider and I briefly touched in this topic in our soon to be published CHC intelligence theory update chapter. Below is the select text and some awesome figures crafted by Joel.

Our simplified conceptual structure of knowledge abilities is presented in Figure 3.10. At the center of overlapping knowledge domains is general knowledge—knowledge and skills considered important for any member of the population to know (e.g., literacy, numeracy, self-care, budgeting, civics, etiquette, and much more). The bulk of each knowledge domain is the province of specialists, but some portion is considered important for all members of society to know. Drawing inspiration from F. L. Schmidt (2011, 2014), we posit that interests and experience drive acquisition of domain-specific knowledge.

In Schmidt's model, individual differences in general knowledge are driven largely by individual differences in fluid intelligence and general interest in learning, also known as typical intellectual engagement (Goff & Ackerman, 1992). In contrast, individual differences in domain-specific knowledge are more driven by domain-specific in-terests, and also by the “tilt” of one's specific abilities (Coyle, Purcell, Snyder, & Richmond, 2014; Pässler, Beinicke, & Hell, 2015). In Figure 3.11, we present a simplified hypothetical synthesis of several ability models in which abilities, interests, and personality traits predict general and specific knowledge (Ackerman, 1996a, 1996b, 2000; Ackerman, Bowen, Beier, & Kanfer, 2001; Ackerman & Heggestad, 1997; Ackerman & Rolfhus, 1999; Fry & Hale, 1996; Goff & Ackerman, 1992; Kail, 2007; Kane et al., 2004; Rolfhus & Ackerman, 1999; Schmidt, 2011, 2014; Schneider et al., 2016; Schneider & Newman, 2015; Woodcock, 1993; Ziegler, Danay, Heene, Asendorpf, & Bühner, 2012).

The Use of Mobile Games to Assess Cognitive Function of Elderly with and without Cognitive Impairment (Journal of Alzheimer's Disease):

Abstract: In the past few years numerous mobile games have been developed to train the brain. There is a lack of information about the relation between the scores obtained in these games and the cognitive abilities of the patients. The aim of this study was to determine whether or not mobile games can be used to assess cognitive abilities of elderly. Twenty healthy young adults, 29 old patients with cognitive impairments (Mini-Mental State Exam (MMSE) [20- 24]) and 27-aged controls participated in this study. Scores obtained in 7 mobile games were correlated with MMSE and the Addenbrooke's Cognitive Evaluation revised (ACE-R). Statistically significant differences were found for all games between patients with cognitive impairments and the aged controls. Correlations between the average scores of the games and the MMSE and ACE-R are significant (R = 0.72 [p < 0.001] and R = 0.81 [p < 0.001], respectively). Scores of cognitive mobile games could be used as an alternative to MMSE and ACE-R to evaluate cognitive function of aged people with and without cognitive impairment at least when MMSE is higher than 20/30.
