The Flynn Effect in MR/ID Capital Cases: To adjust or not to adjust?--That is the question---select PPT slides

I am in the process of finalizing a PPT presentation for an Atkins related invited symposium at APA conference next week. The title of my presentation is in the slide below. (double lick on images to enlarge)





This slide is followed by a few of the introductory slides that related to the first working paper previously posted as part of the Flynn Effect series. Eventually the entire PPT show will be uploaded for on-line viewing. Stay tuned.

The Flynn Effect report series: A biref history of the Flynn Effect--It was NOT given birth by Atkins V Virginia (2002) SCOTUS decision: IAP AP101 Report #8

Another new IAP Applied Psychometrics 101 report (#8) is now available.  The report [A brief history of the Flynn Effect: It was NOT given birth by Atkins v Virginia (2002) SCOTUS decision] is the third in the Flynn Effect series, a series of brief reports that 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.

Abstract for third report.

This is the third in a series of brief reports to define, explain, and summarize the scholarly consensus regarding the validity of the Flynn Effect (FE). This report presents a brief historical summary of origins of the Flynn Effect (norm obsolescence). Historical facts indicate that the concern for IQ norm obsolescence and the concept of an IQ score adjustment procedure pre-dates the U. S. Supreme Court Atkins v Virginia (2002) MR/ID death penalty decision. 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: 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.
