Institute for Applied Psychometrics (IAP) new logo

The votes have been counted (at the IAP logo survey at IQ's Corner blog).  Thank you to all who took the time to vote and send comments.  There was a clear winner.  It is reproduced below....with a slight change in the placement of the bell curve.  And yes...there is a deliberate slight skew to the normal curve...it is more visually eye-catching than a perfect normal curve.  Over the next month I will be working to integrate the new logo in all critical IAP-related blogs and web pages.

Many thanks to my great son-in-law, Anthony, who did all the design work.  He does great work.  It is personal XMAS present to me...and it will be treasured for a long time.

CHC IQ test "Periodic Table of Cognitive Elements" is BACK!!!! WAIS-IV example

Back by popular demand....the McGrew Table of CHC Cognitive Elements....now revised and improved.  

Below are a set of slides that include the new periodic table of cognitive elements and its use in a visual-graphic CHC summary of the WAIS-IV.  Stay tuned...more of these are in the works.

The IAP AP 101 WAIS-IV report link included in one of the slides can also be accessed by clicking here.

Images can be enlarged by double clicking on them.  Enjoy.

Institute for Applied Psychometrics (IAP) internet resourcs (web, blogs, etc.) updated/revised

This blog, as well as my other two professional blogs, are activities of the Institute for Applied Psychometrics (IAP).  I'm pleased to announce that this past week I finally found the time to update/revise the IAP web page. 

Aside from updating content, the major revision was the integration and cross-linking of the IAP web page with my three professional blogs.  The web page serves more as the "mother" host of major static material while the three blogs are the IAP's mechanisms (along with Facebook, LinkedIN and Twitter---page links that are now also available at the revised web page) for immediate, dynamic presentation of material.  Collectively all of these internet portals work together to meet the goals of IAP (as outlined below).  The sources are now better integrated via the latest web page revision.  Enjoy

You can access the IAP web page via three methods:

The Institute for Applied Psychometrics (IAP) llc is a private research organization, founded by Kevin McGrew, devoted to the application of educational, psychological, measurement and statistical procedures to issues and problems in psychology, education, and human exceptionalities/disabilities.  The goal of IAP is to provide a bridge between psychological, measurement, and statistical theory/methods and applied practice in psychology, education and law.

IAP has particular research interests in: (a) theories and measurement of human intelligence, personal competence and adaptive behavior, (b) the application of psychological and educational measurement principles and techniques to the development and interpretation of psychological and educational assessment instruments, (c) the Cattell-Horn-Carroll (CHC) Theory of Cognitive Abilities, (d) narrowing the theory-practice gap in educational and psychological assessment, (c) the influence of non-cognitive (conative) characteristics on learning and human performance, (d) psychological assessment practices in the identification and classification of individuals with intellectual and learning disabilities and other exceptionalities, (e) the application of emerging neurotechnologies to learning and cognitive performance, and (f) psychometric issues related to the identification of individuals with intellectual disabilities in Atkins MR/ID death penalty cases.  The practical application of psychometrics to educational, psychological and legal problems is a unique IAP focus.

IAP has conducted research and provided consultation and training on:

  • Human ability measurement as per the Cattell-Horn-Carroll (CHC; Gf-Gc) Theory of Cognitive Abilities.
  • Achievement and cognitive ability test development and interpretation.
  • The practical application of IRT, multivariate statistics, and structural equation modeling (SEM) methods to educational and psychological issues and problems.
  • Research, development, and validation of models of human abilities and competence, particularly in the areas of multiple intelligence's, academic and cognitive skill development, personal competence, adaptive behavior, and community adjustment.
  • The development and measurement of educational and community outcomes for individuals with disabilities.
  • Secondary analysis of large-scale national databases.
  • The development and improvement of educational assessment practices for students with disabilities.
  • The development of strong programs of construct validity for educational and psychological assessment and measurement methods.
  • Recognizing the importance on non-cognitive (e.g., self-regulated learning strategies; self- efficacy; etc) student characteristics in academic learning.
  • Psychometric issues surrounding intelligence testing in federal Atkins MR/ID death penalty cases.
  • Scientific advice to neurotechnology companies (i.e., Interactive Metronome).
  • Education regarding applied psychometric topics.

Cluster analysis of the WJ III: Implications for test interpretation and CHC model extensions




IAP AP101 # 4 report is now available (click here for all AP101 reports and briefs).  "IAP AP101 Report #4: Cluster analysis of the WJ III Battery:  Implications for CHC test interpretation and possible CHC model extensions" can be downloaded or viewed by clicking here.

PPT files are also viewable and downloadable via SlideShare.

Abstract
The WJ III Battery is comprised of both cognitive (intelligence) and achievement components. As reported in the technical manual, the Cattell-Horn-Carroll (CHC) theory of cognitive abilities organizational structure of the WJ III has been validated. The current investigation analyzed the cognitive and achievement tests for all WJ III norm subjects from ages 6-18 years of age. Cluster analysis of the 50 WJ III tests provides additional validity for the CHC structure of the WJ III. More importantly, the analyses provide support for a significant number of narrow ability classifications for many WJ III tests, classifications that (to date) have largely been based on expert consensus task analysis. The results also suggest possible new interpretative clusters and intermediate CHC dimensions warranting future research regarding the CHC taxonomy of human cognitive abilities.

IQs Corner Recent Literature of Interest and Reference Database explained

Members of the CHC listserv receive a weekly FYI notes (from the blogmaster) indicating that "IQs Corner Recent Literature of Interest" (for that week) has been posted at IQ's Corner Blog (click here to see recent example) With some degree of regularity I'm often asked why the posted reference lists are not just focused on intelligence and intelligence testing topics. Below is an explanation as well as a description of the resources that makes this weekly update possible.

The Institute for Applied Psychometrics (IAP) originally started the IAP Reference Database. This reference manager database is a weekly updated computerized database of literature selected because of its relevance to the activities and interests of yours truly, the Director of IAP and the Research Director of WMF. These activities and interests extend well beyond intelligence and testing. All social and behavioral sciences journals listed in each weeks installment of Current Contents/Social and Behavioral Sciences are searched on a weekly basis. Selected references are imported into the system. A deliberately wide search net is cast.

These activities has been occurring since 1994. The Reference Database is managed using Procite software The current database (12-17-08) includes over 34,000 records. The references in the Reference Database can be searched via select terms, keywords, authors, journal, and many combinations of search term.

If you want to receive the weekly literature updates you will need to join the CHC listserv.

Thanks....the blogmaster.Technorati Tags: , , , , , , , , , , , , , ,

IAP web page updated--yipppeeeeee


Within the past two weeks I've updated (finally) my IAP (Institute for Applied Psychometrics) web page. It now allows for the dynamic linking of the more static information of the IAP web page with the hot/dynamic information in my two blogs and EWOKS. Check it out. Book mark. Visit it frequently.
