Mental imagery debate

Another great post over at the Developing Intelligence blog re: a recap of the debate regarding mental imagery. Below is a the URL link to the complete post (which includes links to other good stuff) and the first paragraph of the post. Thanks DI for your continued great stuff.

Pictures in the Brain (click here)

  • "The new issue of Scientific American Mind has a nice recap on the mental imagery debate, which has been going strong for over 10 years now. The debate proceeds roughly as follows: when we imagine something, are we merely activating its abstract, propositional representation in long term memory, or is imagination actually a process of neurally reinstantiating this distributed information into a visual form available for inspection and spatialmanipulation?"

Executive functioning - excellent post from DI blog

I must confess that Chris Chatham's Developing Intellignence blog is becomming one of my favorites. At times the material is quite complex and deals with intelligence at a different level than the focus of my work and writings at IQs corner, but many times it is well worth the read.

Today he has one of the better posts I've recently read about executive functioning. Below is the URL to his post and the first paragraph of his rather lengthy post (full of links to articles, etc.). This is a post worth reading.

Under The Rug: Executive Functioning

  • If you want to build an intelligent and biologically-plausible system, you of course need an actuator or motor subsystem, object recognition capability, several different kinds of memory capacity, and probably several other subsystems corresponding to various regions of the human brain. But what kind of subsystem would be capable of orchestrating
    these capacities and coordinating them to produce intelligent behavior? To put it another way, does intelligence consist entirely in interactions between various capacities, or is there a cognitively- and anatomically-distinct agent that coordinates them? These questions (albeit in slightly different form) are the same as those confronted in
    "executive functioning" research.

SAT scores predict more than expected for top stops

Hat tip to the Science Blog for the post re: recent research suggesting that extremely high SAT scores may have strong relations to success beyond typical college outcome measures. Below is the link and a brief intro blurb from the post....(go to the site to read more)

SAT Gauges More Than Collegiate Success

"On February 13, high-school juniors and seniors were able to access their January 2006 SAT scores through the College Board website. The test is an important step toward gaining college acceptance. But new research shows that the test may go far beyond predicting college success; when taken in the early teens, it may actually foretell a person’s success and life satisfaction after university."

Linguistic complexity anlaysis of test directions

Over on the IAP CHC listserv I made mention of the analysis of certain WJ III tests as per the linguistic demands placed on examinees during the test directions. Questions were asked about the methods used to generate the two empirical indexes I mentioned in my post---viz., verbosity and complexity.

Information regarding these procedures can be found in the following unpublished manuscript (click here to view or download)

McGrew, K & Evans, J. (2006). Quantifying the “Degree of Linguistic Demand” in Spoken Intelligence Test Directions: A Preliminary Report. Unpublished manuscript, Institute for Applied Psychometrics, St. Cloud, Mn.


Abstract
  • The linguistic demand of spoken instructions on norm-referenced psychoeducational tests is of concern when examining students who have varying levels of language processing ability, or varying cultural backgrounds. We present a new method for analyzing verbosity, complexity and total demand of spoken directions for test batteries. This preliminary methodological investigation suggests that it is possible, and relatively easy, to gather useful empirical information regarding the complexity of spoken test directions using existing (readily available) text readability programs. It is suggested that best practice for individually administered psychoeducational tests may be to include this information when tests are published and/or compared.

Rethinking/revisiting the concept of "aptitude"

I was digging through some old electronic notes this evening from the book "Remaking the Concept of Aptitiude: Extending the Legacy of Richard E. Snow" and felt a need to share some text from the first chapter.

I believe that Richard Snow's concept of "aptitude", which has its roots in the original/historical notions of construct, needs to command more attention of practicing psycholgogists, esp. those working in the schools. That is, both a student's cognitive and conative abilities need to be considered in educational planning. Below is some selected text that helps define the concept of aptitude and how it differs from ability.

Just some food for thought........
  • Managers try to arrange conditions to get the best from the people they hire. In the same way, teachers strive to arrange the learning situation to get the best from their students. The conditions that bring out the best in one employee or student, however, may not inspire another. Each person has worked out over many years how to respond in her own way to symbol systems and social cues. Each has aptitude for particular situations. Recognizing specifically the qualites each person brings to a situation, then adiusting the situation to improve the fitt-these are major tasks of those who work with people
  • Aptitude, said Snow, should refer to being equipped to work at a particular kind of task or in a particular kind of situation.
  • The concept of aptitude ls especially close to that of readiness (as in “reading readlness”), suitability (for a purpose or position), susceptability (to treatment or persuasion), proneness (as in “accident-prone"). All imply a predisposition to respond in away that fits, or does not fit, a particular situation or class of situations. The common thread is potentiality-a latent quality that enables the development or production, given specified conditions, of some more advanced performance. (See Scheffler, 1985.) In this book we use the term aptitude to mean degree of readiness to learn and to perform well in a particular situation or in a fixed domain.
  • Ability is a generic term referring to the power to carry out some type of undertaking. Abilities are of many kinds: reading comprehension, spatial ability, perceptual speed, knowledge of (for example] geography, and physical coordination. Each facilitates functionning in some kinds of situation.
  • Although every situation draws on abilities, aptitude is not limited to ability. Aspects of personality--achievement motivation, freedom from anxiety, appropriately positive self-concept, control of impulses,and others--are aptitudes as well, contributing importantly to coping with some challenges. The opposite qualities—anxious caution or impulsiveness, for example--can also be assets (i.e., aptitude) at certain moments.
  • A complete theory of aptitude, then, must consider affective and conative processes as well as abilities.

"Nonverbal" intelligence - UNIT and Leiter-R comparisons

The recent issue of Psychology in the Schools included an article by Hooper and Bell (2006) that explored the concurrent validity of the Universal Nonverbal Intelligenence Test (UNIT) and the Leiter International Performance Scale--Revised (Leiter-R).

Abstract
  • One hundred elementary- and middle-school students were administered the Universal Nonverbal Intelligence Test (UNIT; B.A. Bracken & R.S. McCallum, 1998) and the Leiter International Performance Scale-Revised (Leiter-R; G.H. Roid & L.J. Miller, 1997). Correlations between UNIT and Leiter-R scores were statistically significant ranging from .33 to .74. The UNIT Full Scale score was 5 points higher than the Leiter-R Full Scale score. [Click here to view/read entire article]

A few blogmaster comments:
  • I wish folks would quit using the phrase "nonverbal intellignce." I've written elsewhere (and so have many others...Flanagan, Woodock, Keith, Kamphaus...to name a few) that there is no such thing as "nonverbal" intelligence from a strict construct validity perspective. Nowhere will you find "nonverbal" intelligence in the Carroll's seminal review of the factor analytic research on human abilities. These batteries assess "abilities, nonverbally." In particular, most of these batteries measure the CHC abilities of Gf, Gv, Gs and Glr via nonverbal methods...not "nonverbal intelligence."
  • As would be expected, the composite IQ scores were highly correlated (.72). However, this still indicates that the global IQ scores are not exchangeable. This level of correlation suggests approximately 50% shared variance. So...how are practitioners supposed to interpret and understand the differences in scores? Flanagan and I previously provided CHC analysis of the tests in these two batteries in the Intelligence Test Desk Reference (ITDR). If you click here you will be taken to an abbreviated table (from the ITDR) that presents our CHC classification of the tests from the two batteries. This information should assist practitioners determine the possible reasons for score differences based on differences in CHC abilities measured by the two batteries.
  • Both of these are nice psychometricaly sound batteries authored by well-respected folks.

Excellent working memory review article

FYI - An excellent review article on working memory tasks. The article title, abstract, and link to a copy of article is provided below. The artilce is a good user's guide on the status of three types of working memory tasks often used in cognitive psychology research... counting, operation and reading span tasks. It also provides a nice overview of the history of working memory tasks and the state-of-the-art on the research conducted with these types of task to date.

In addition, the article presents a concise description of the Conway et al's model of working memory that features the notion of domain-general executive attention ( I would recommend reading that brief section to better understand this influential model of working memory). According to Conway et al., " We view WM as a multicomponent system responsible for active maintenance of information in the face of ongoing processing and/or distraction. Active maintenance of information is the result of converging processes—most notably, domain-specific storage and rehearsal processes and domain-general executive attention. Furthermore, the extent to which maintenance depends on domain-specific skills versus domain-general executive attention varies as a function of individual ability, task context, and ability × context interactions."

Of the working memory models I've reviewed, this domain-general executive attention mechanism-based model is one that resonates best to what I've gleaned from my personal reading of the research. Just my two cents.

Conway, A., Kane, M., Bunting, M., Hambrick, D and Wilhelm, O. (2005) Working memory span tasks: A methodological
review and user’s guide. Psychonomic Bulletin Review, 12 (5), 769-786


Abstract

  • Working memory (WM) span tasks—and in particular, counting span, operation span, and reading span tasks—are widely used measures of WM capacity. Despite their popularity, however, there has never been a comprehensive analysis of the merits of WM span tasks as measurement tools. Here, we review the genesis of these tasks and discuss how and why they came to be so influential. In so doing, we address the reliability and validity of the tasks, and we consider more technical aspects of the tasks, such as optimal administration and scoring procedures. Finally, we discuss statistical and methodological techniques that have commonly been used in conjunction with WM span tasks, such as latent variable analysis and extreme-groups designs.

Effect of child care on cognitive development-NICHD study

Important article (Child-Care Effect Sizes for the NICHD Study of Early Child Care and Youth Development) in current American Psychologist (2006, 61[2],99-116) by the NICHD Early Child Care Research Network re: the effect of child care on a number of outcomes, including cognitive and language abilities. Click here to read......

Abstract and select summary conclusions noted below (italics added by blogmaster)

Abstract
  • This report summarizes findings from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development as effect sizes for exclusive maternal care and—for children in child care—type, quality, and quantity of care. Children (n = 1,261) were recruited at birth and assessed at 15, 24, 36, and 54 months. Exclusive maternal care did not predict child outcomes, but multiple features of child-care experience were modestly to moderately predictive. Higher quality child care was related to advanced cognitive, language, and preacademic outcomes at every age and better socioemotional and peer outcomes at some ages. More child-care hours predicted more behavior problems and conflict, according to care providers. More center-care time was related to higher cognitive and language scores and more problem and fewer prosocial behaviors, according to care providers. Child-care effect sizes are discussed from 3 perspectives: (a) absolute effect sizes, reflecting established guidelines; (b) relative effect sizes, comparing child-care and parenting effects; and (c) possible individual and collective implications for the large numbers of children experiencing child care. Specifically, whether a child was in child care and child-care quality, quantity, and type were linked to both family characteristics and child outcomes. Families opting to use exclusive maternal care tended to be less advantaged. The mothers choosing exclusive maternal care had less income, less education, more depressive symptoms, and less sensitive parenting skills. In contrast, more advantaged families tended to place their child in higher quality care, in child care for more hours per week, and in center care for a longer period. Higher quality care was associated with more income, two-parent households, more maternal education, less maternal depression, and being in the White ethnic group. Children who experienced more hours of child care or who spent more time in center care tended to be from families with more income and mothers with more education. Use of center care was also associated with more positive parenting. These findings provide further evidence (cf. Lamb, 1998; Vandell, 2004) that family characteristics must be taken into account when asking whether child-care experiences are related to child outcomes
Select highlights
  • Almost no evidence emerged suggesting that child outcomes were related to whether the child experienced routine nonmaternal care (seeNICHD ECCRN, 1998, 2000a). As can be seen in the first column of Table 5, only one outcome—the Bayley Mental Development Index assessed at 24 months—showed statistically significant differences between children reared exclusively in maternal care and children experiencing child care. Use of child care was not significantly or substantively related to cognitive outcomes at 15, 36, or 54 months or to social or peer outcomes at any age. Follow-up analyses asked whether quality of parenting was more strongly related to outcomes depending on whether the child was cared for exclusively by the mother. None of the interactions achieved statistical significance
  • Overall, parenting showed moderate-to-large effect sizes, suggesting that children who experienced more responsive and stimulating care from parents had higher scores on cognitive, language, social-emotional, and peer outcomes at all ages.
  • Longitudinal analyses from 24 to 54 months (adjusted statistically for family selection factors by including these as covariates) documented clear and, for the most part, consistent relations between child-care experience during the infant, toddler, and preschool years and children's cognitive, language, and socioemotional development. Overall, parenting emerged as a consistent and strong predictor of all child outcomes, child-care quality was a consistent and modest predictor of most child outcomes, child-care quantity was a consistent and modest predictor of social behavior, and child-care type was an inconsistent and modest predictor of cognitive and social outcomes. In addition, comparisons between children with exclusive maternal care and children in child care yielded only one significant difference over time and across outcomes—a rate less than what would be expected by chance alone. These findings provide compelling evidence that knowledge about whether a child is in care, in and of itself, cannot inform predictions of child development. Knowledge concerning variations in multiple features of parenting and child-care experience for those children in child care can inform such predictions.

LD children and spelling treatment effect on fMRIs

Thanks to Andrew Livanis (School Psychology blog) for the folllowing.

Brain Images Show LD Children Respond To Spelling Treatment

  • "One of the interesting things about reading disorders is that children with a positive diagnosis tend to show different patterns of brain activity that non-identified children. This is a brief summary of reserach (too brief in my opinion - I would have liked to have seen more of it) in which a treatment showed positive results as shown through pre- and post- fMRI patterns. Specifically, the LD groups post fMRI patterns more closely resembled the non-LD children's fMRI patterns."

More popular press Flynn Effect coverage

By IQ scores, kids smarter these days


  • WASHINGTON
    — If judged solely by their IQ scores, today’s kids are smarter than
    any generation since testing began — so smart that many of their
    great-grandparents would have been found mentally deficient by today’s
    standards.....

.......click URL above to read.

However, take the article with a hugh grain of salt. As I reported at last Decembers ISIR conference, new research (with more comprehensive measures of intelligence and more sophisticated statistical methodology) is suggesting that the Flynn Effect may have stopped and may be only occuring on very narrow abilities. The paper ISIR presented by Jelte Wicherts et al was clearly one of the presentations that caught the attention of the serious intelligence scholars who published in the rarified air of the journal Intelligence. Word from the invisible university network is that a new round of critical arguements for, and against, the Flynn Effect are bubbling among the major players. Stay tunned. It is going to get interesting.
