The Flynn Effect report series: Is the Flynn Effect a Scientifically Accepted Fact? IAP AP101 Report #7

Another new IAP Applied Psychometrics 101 report (#7) is now available.  The report is the second in the Flynn Effect series, a series of brief reports that will define, explain and discuss the validity of the Flynn Effect (click here to access all prior FE related posts at the ICDP blog) and the issues surrounding the application of a FE "adjustment" for scores based on tests with date norms (norm obsolescence), particularly in the context of Atkins MR/ID capital punishment cases.  The abstract for the brief report is presented below.  The report can be accessed by clicking here.

Report # 1 (What is the Flynn Effect) can be found by clicking here.

This report is the second in a series of brief reports the will define, explain, and summarize the scholarly consensus regarding the validity of the Flynn Effect (FE). This brief report presents a summary of the majority of FE research (in tabular form of n=113 publications) which indicates (via a simple “vote tally” method) that despite no consensus regarding the possible causes of the FE, it is overwhelming recognized as a fact by the scientific community. The series will conclude with an evaluation of the question whether a professional consensus has emerged regarding the practice of adjusting dated IQ test scores for the Flynn Effect, an issue of increasing debate in Atkins MR/ID capital punishment hearings.

The Flynn Effect report series: What is the Flynn Effect: IAP AP101 Report #6

A new IAP Applied Psychometrics 101 report (#6) is now available.  The report is the first in the Flynn Effect series, a series of brief reports that will define, explain and discuss the validity of the Flynn Effect (click here to access all prior FE related posts at the ICDP blog) and the issues surrounding the application of a FE "adjustment" for scores based on tests with date norms (norm obsolescence), particularly in the context of Atkins MR/ID capital punishment cases.  The abstract for the brief report is presented below.  The report can be accessed by clicking here.

Norm obsolescence is recognized in the intelligence testing literature as a potential source of error in global IQ scores.  Psychological standards and assessment books recommend that assessment professionals use tests with the most current norms to minimize the possibility of norm obsolescence spuriously raising an individual’s measured IQ.  This phenomenon is typically referred to as the Flynn Effect.  This report is the first in a series of brief reports the will define, explain, and summarize the scholarly consensus regarding the validity of the Flynn Effect.  The series will conclude with an evaluation of the question whether a professional consensus has emerged regarding the practice of adjusting dated IQ test scores for the Flynn Effect, an issue of increasing debate in Atkins MR/ID capital punishment hearings.

Research Bytes 6-28-10: Aging research--Gf and stress; decision-making mediated by Gs and Gsm?

Interesting articles of potential interest.  Anyone who would like to read the complete articles in exchange for writing a "brief" blog post about the article should contact the blogmaster @ iap@earthlink.net

Henninger, D. E., Madden, D. J., & Huettel, S. A. (2010). Processing Speed and Memory Mediate Age-Related
Differences in Decision Making. Psychology and Aging, 25(2), 262-270.

Decision making under risk changes with age. Increases in risk aversion with age have been most commonly characterized, although older adults may be risk seeking in some decision contexts. An important, and unanswered, question is whether these changes in decision making reflect a direct effect of aging or, alternatively, an indirect effect caused by age-related changes in specific cognitive processes. In the current study, older adults (M = 71 years) and younger adults (M = 24 years) completed a battery of tests of cognitive capacities and decision-making preferences. The results indicated systematic effects of age upon decision quality—with both increased risk seeking and increased risk aversion observed in different tasks—consistent with prior studies. Path analyses, however, revealed that age-related effects were mediated by individual differences in processing speed and memory. When those variables were included in the model, age was no longer a significant predictor of decision quality. The authors conclude that the reduction in decision quality and associated changes in risk preferences commonly ascribed to aging are instead mediated by age-related changes in underlying cognitive capacities

Stawski, R. S., Almeida, D. M., Lachman, M. E., Tun, P. A., & Rosnick, C. B. (2010). Fluid Cognitive Ability Is
Associated With Greater Exposure and Smaller Reactions to Daily Stressors. Psychology and Aging, 25(2),
330-342.

The authors of this study investigated whether fluid cognitive ability predicts exposure and emotional reactivity to daily stressors. A national sample of adults from the Midlife in the United States study and the National Study of Daily Experiences (N = 1,202) who had a mean age of 57 years (SD = 12; 56% women, 44% men) completed positive and negative mood reports as well as a stressor diary on 8 consecutive evenings via telephone. Participants also completed a telephone-based battery of tests measuring fluid cognitive ability. Higher levels of fluid cognitive ability were associated with greater exposure to work- and home-related overload stressors. Possessing higher levels of fluid cognitive ability was associated with smaller stressor-related increases in negative mood, primarily for interpersonal tensions and network stressors, and smaller stressor-related decreases in positive mood for interpersonal tensions. Furthermore, fluid cognitive ability was unrelated to subjective severity ratings of the stressors reported. Discussion focuses on the role of fluid cognitive ability in daily stress processes.

Use of WJ III NU Cognitive and Achievement batteries in Canada: ASB #12 Report now available

ASB #12 Use of the Woodcock-Johnson III NU Tests of Cognitive Abilities and Tests of Achievement with Canadian Populations  is now available for download at the Riverside Publishing web site (click here).

As described at the Riverside web page:

This bulletin examines the use of the Woodcock-Johnson III Normative Update (WJ III NU) Tests of Cognitive Abilities and Tests of Achievement  with a random sample of 310 school-age Canadian students. Results were compared with a matched sample of U.S. subjects selected from the WJ III NU standardization sample using WJ III NU norms. While some minor score differences are reported across the two samples, the study findings generally support the use of the U.S.-based WJ III NU norms with Canadian school-age populations.

Speech rhythm perception (Ga?) important for early reading

Holliman, A. J., Wood, C., & Sheehy, K. (2010). Does Speech Rhythm Sensitivity Predict Children's Reading Ability 1 Year Later? Journal of Educational Psychology, 102(2), 356-366.

There is a growing literature demonstrating that speech rhythm sensitivity is related to children's reading development, independent of phonological awareness. However, the precise nature of this relationship is less well understood, and further research is warranted to investigate whether speech rhythm sensitivity predicts the different components of reading over time. In this 1-year longitudinal study, 69 five- to 8-year-old English-speaking children completed a speech rhythm assessment at Time 1 along with other cognitive assessments and then completed a variety of reading assessments at Time 2 (1 year later). A series of hierarchical regression analyses revealed that after controlling for individual differences in age, vocabulary, and phonological awareness, speech rhythm sensitivity was able to predict unique variance in word reading and the phrasing component of the reading fluency measure 1 year later. The findings emphasize the contribution of speech rhythm sensitivity in children's reading development, and the authors argue that speech rhythm sensitivity should now be included in current models of children's reading development.

Speech rhythm was measured via the revised mispronounciations task:  As described in the article:

Speech rhythm sensitivity was measured using the revised mispronunciations task (Holliman et al., in press). Children heard a prerecorded word that was sounded through a speaker, where the stress of that word had been manipulated and reversed. For example, in the normal pronunciation of the word carrot [kær?t], the vowel in the first syllable is fully articulated and the vowel in the second syllable is reduced. However, in this task the stress was reversed so that the vowel in the first syllable became reduced and the vowel in the second syllable was fully articulated; carrot was pronounced as “c’rot” [k?'r?t]. To succeed in this task, children would need to be sensitive to the fact that the stress had been manipulated, and be
able to recover the correct stress, making a stress shift (Kitzen, 2001) to match the auditory input to a word stored in the lexicon, and then identify the corresponding target item from a choice of four pictures available.

Research bytes 6-20-2010: Cognitive correlates of bilingualism; morphological instruction and literacy

Adesope, O. O., Lavin, T., Thompson, T., & Ungerleider, C. (2010). A Systematic Review and Meta-Analysis of the Cognitive Correlates of Bilingualism.  Review of Educational Research, 80(20), 207-245.

A number of studies have documented the cognitive outcomes associated  with bilingualism. To gain a clear understanding of the extent  and diversity of these cognitive outcomes, the authors conducted  a meta-analysis of studies that examined the cognitive correlates  of bilingualism. Data from 63 studies (involving 6,022 participants) were extracted and analyzed following established protocols and procedures for conducting systematic reviews and guidelines for meta-analysis. Results indicate that bilingualism is reliably associated with several cognitive outcomes, including increased attentional control, working memory, metalinguistic awareness, and abstract and symbolic representation skills. Overall mean effect sizes varied from small to large, depending on the cognitive outcomes measured, and were moderated by methodological features of the studies.

Bowers, P. N., Kirby, J. R., & Deacon, S. H. (2010). The Effects of Morphological Instruction on Literacy Skills: A Systematic Review of the Literature. Review of Educational Research, 80(2), 144-179.

The authors reviewed all peer-reviewed studies with participants from preschool to Grade 8 for this meta-analysis of morphological interventions. They identified 22 applicable studies. Instructional effects (Cohen’s d) were averaged by linguistic outcome categories (morphological sublexical, nonmorphological sublexical, lexical, and supralexical) and comparison group (experimental group vs. control or experimental group vs. alternative training). The authors investigated the effects of morphological instruction (a) on reading, spelling, vocabulary, and morphological skills, (b) for less able readers versus undifferentiated samples, (c) for younger versus older students, and (d) in combination with instruction of other literacy skills or in isolation. Results indicate that (a) morphological instruction benefits learners, (b) it brings particular benefits for less able readers, (c) it is no less effective for younger students, and (d) it is more effective when combined with other aspects of literacy instruction. Implications of these findings are discussed in light of current educational practice and theory.

Handbook of Pediatric Neuropsychology: Woodock-Johnson III chapter

NOTE -- after making this post I've learned that I may not have had appropriate position to post a link to the PDF copy of the WJ III chapter.  Thus, those URL's have been temporarily deactivated.  I will reactivate if I get clearance.  Sorry.

The forthcoming Handbook of Pediatric Neuropsychology (Dr. Andrew Davis) can now be pre-ordered from Springer Publishing.

A description of the book, at the publisher website, is below:

This handbook covers basic neurodevelopmental research that any pediatric neuropsychologist will need to know. The authors discuss practical issues in pediatric assessment, and provide a comprehensive overview of the most common medical conditions that neuropsycholoigists encounter while dealing with pediatric populations.

The book also describes a variety of professional issues that neuropsychologists must confront during their daily practice, such as ethics, multiculturalism, child abuse, forensics, and psychopharmacology. Also discussed are school-based issues such as special education law, consulting with school staff, and reintegrating children back into mainstream schools.

An incomplete table of contents is available at the website.  The complete TOC is listed below...it includes 95 chapters...yes, that is correct!!!!!  Simply a major tome.

I received an advanced copy of the chapter dealing with the WJ III Tests of Cognitive Abilities (Dr. Fred Schrank).  This chapter is unique in that it is the first comprehensive presentation of research results regarding WJ III cluster and test scores on over 2,200 subjects with a variety of clinical diagnoses (ADHD, anxiety spectrum disorders, head injury, autism spectrum disorders, types of learning disabilities, MR/ID, etc.) who are part of the Woodcock-Munoz Foundation Clinical Data Base.

iPost: Subscores based on MIRT methods

Reporting of Subscores Using Multidimensional Item Response Theory

Journal	Psychometrika
Publisher	Springer New York

Abstract  

Recently, there has been increasing interest in reporting subscores. This paper examines reporting of subscores using multidimensional item response theory (MIRT) models (e.g., Reckase in Appl. Psychol. Meas. 21:25–36, 1997; C.R. Rao and S. Sinharay (Eds), Handbook of Statistics, vol. 26, pp. 607–642, North-Holland, Amsterdam, 2007; Beguin & Glas in Psychometrika, 66:471–488, 2001). A MIRT model is fitted using a stabilized Newton–Raphson algorithm (Haberman in The Analysis of Frequency Data, University of Chicago Press, Chicago, 1974; Sociol. Methodol. 18:193–211, 1988) with adaptive Gauss–Hermite quadrature (Haberman, von Davier, & Lee in ETS Research Rep. No. RR-08-45, ETS, Princeton, 2008). A new statistical approach is proposed to assess when subscores using the MIRT model have any added value over (i)  the total score or (ii)  subscores based on classical test theory (Haberman in J. Educ. Behav. Stat. 33:204–229, 2008; Haberman, Sinharay, & Puhan in Br. J. Math. Stat. Psychol. 62:79–95, 2008). The MIRT-based methods are applied to several operational data sets. The results show that the subscores based on MIRT are slightly more accurate than subscore estimates derived by classical test theory.

The cognitive constructs working memory (WM) and processing speed are fundamental components to general intellectual functioning in humans and highly susceptible to disruption following neurological insult. Much of the work to date examining speeded working memory deficits in clinical samples using functional imaging has demonstrated recruitment of network areas including prefrontal cortex (PFC) and anterior cingulate cortex (ACC). What remains unclear is the nature of this neural recruitment. The goal of this study was to isolate the neural networks distinct from those evident in healthy adults and to determine if reaction time (RT) reliably predicts observable between-group differences. The current data indicate that much of the neural recruitment in TBI during a speeded visual scanning task is positively correlated with RT. These data indicate that recruitment in PFC during tasks of rapid information processing are at least partially attributable to normal recruitment of PFC support resources during slowed task processing.
