Georgia Judge Would Allow Execution of Intellectually Disabled Man, But Calls for Higher Court Review [feedly]



----
Georgia Judge Would Allow Execution of Intellectually Disabled Man, But Calls for Higher Court Review
// Death Penalty Information Center

A county judge in Georgia denied relief for Warren Hill, a death row inmate whose diagnosed intellectual disabilities have failed to meet the state's narrow standard for exemption from the death penalty. However, the judge encouraged the state Supreme Court to consider whether a recent U.S. Supreme Court ruling, Hall v. Florida, should require Georgia to modify its standard. Chief Judge Thomas Wilson of Butts County said, "In light of the severity of the penalty in this case, this Court hopes that, in reviewing [Mr. Hill's] application to appeal, the Georgia Supreme Court will fully consider any potential application of Hall v. Florida to [his] case." In Hall v. Florida, the Supreme Court directed Florida to broaden its interpretation of intellectual disability. Florida refused to spare an inmate whose IQ was just one point above their cutoff. Similarly, Georgia has the narrowest standard of proof for intellectual disability in the entire country, requiring defendants to prove their disability beyond a reasonable doubt. Brian Kammer, an attorney for Hill, said,"Mr. Hill should not be eligible for execution in a nation which does not execute persons with intellectual disability, and he would not be eligible for execution in any other jurisdiction in the nation."

The victim's family in Hill's case has also said that they do not support his execution. Several jurors from his trial have said that they would have recommended a sentence of life without parole if it had been an option at the time. National and state organizations focusing on intellectual disabilities have supported Hill's claim. President Jimmy Carter and Rosalyn Carter have called for a commutation of Mr. Hill's death sentence to life without parole. Additionally, the American Bar Association, the ACLU, and the Council of Europe have all called for sparing Hill's life.

(Hill v. Chatman, Order, September 29, 2014; E. Jacobson (Executive Director of the Georgia Council on Developmental Disabilities), "The Supreme Court Must Stop the Execution of Warren Hill," Huffington Post, February 11, 2013). See Intellectual Disability and Supreme Court.

"Scientizing Culpability: The Implications of Hall v. Florida and the Possibility of a 'Scientific Stare Decisis'" [feedly]



----
"Scientizing Culpability: The Implications of Hall v. Florida and the Possibility of a 'Scientific Stare Decisis'"
// Sentencing Law and Policy

The title of this post is the title of this notable new paper available on SSRN authored by Christopher Slobogin. Here is the abstract:

The Supreme Court's decision in Hall v. Florida holds that "clinical definitions" control the meaning of intellectual disability in the death penalty context. In other words, the Court "scientized" the definition of intellectual disability. This article discusses the implications of this unprecedented move. It also introduces the idea of scientific stare decisis — a requirement that groups that are scientifically alike be treated similarly for culpability purposes — as a means of implementing the scientization process.

WJ IV update: Correlations of WJ IV COG g-scores (GIA,Brief,Gf-Gc composite) and WISC-IV/WAIS-IV FS and GAI IQ scores

In the WJ IV technical manual (McGrew, LaForte, Schrank, 2014) concurrent validity results are presented for the WJ IV COG with the WISC-IV and WAIS-IV (click here for WJ IV COG overview and select correlation information from tech. manual).

A number of psychologists have asked about correlations between the primary WJ IV COG g-scores and the Wechsler General Ability Index (GAI).  They are not presented in the technical manual.  I have now computed those correlations, as well as a few others with the Wechsler GAI, and they are now part of the SlideShare at the link above and are also reported below.  Click on image to enlarge.

Quotes to note: Importance of high quality psychological testing to psychologists




I just read this nice statement at the begging of the following article by Robert J. Ivnik, Ph.D., ABPP Professor of Psychology, Mayo Clinic College of Medicine, Rochester, MN.

The only professional services that are uniquely psychology's are testing-based assessments. Every other service that psychology offers can be obtained from other professions. In light of testing's central importance to our profession, and considering the number of years that psychologists have been practicing, we assure that our tests are scientifically sound and have been validated for the purposes to which they are put (e.g., research proves that our tests make accurate predictions). Correct? After all, in today's health care environment would any profession knowingly expose its core service to potential attack?

Although testing-based assessments are psychology's defining feature, they may also be our profession's Achilles' heel. Unfortunately, the manner in which many tests have been developed, standardized, normed, and validated may be most kindly described as ‘‘varied'' when it comes to scientific rigor. The science behind some of psychology's older and commercially successful tests tends to be stronger when some of the profit accrued by their sale is devoted to improving the tests. Lacking similar financial resources, many other tests have simply not been developed or validated very well

Fwd: [ABA-3D] Webinar Announcement



Suspects/Offenders' Issues Series:

Alternatives to Incarceration for Criminal Offenders with Developmental and Intellectual Disabilities

 

August 28, 1:30-2:30 p.m. EST

Jessica S. Oppenheim, Esq.

Director of the Criminal Justice Advocacy Program of The Arc of New Jersey


Criminal Offenders with developmental and intellectual disabilities (I/DD) present unique challenges to the criminal justice system seeking to investigate and prosecute crime as well as to the social service system seeking to serve and assist this vulnerable population. Such individuals make up at least 9 – 10% of the prison population and some studies tell us that they may comprise as much as 50% of adult and juvenile offender populations. It is unquestioned that individuals with I/DD face distinct disadvantages in the system, resulting in convictions for more serious offenses and more prison time.

 

The Criminal Justice Advocacy Program (CJAP) of The Arc of NJ seeks to overcome these disadvantages, while still ensuring that offenders take responsibility for criminal behavior, by arranging specific interventions that provide alternatives to incarceration through offender-specific Personalized Justice Plans. The CJAP also acts as a clearinghouse of information between the criminal justice and social service system in provide training and communication between the two systems. This webinar will review the obstacles and disadvantages faced by this population and provide an overview of the CJAP.  Register here

Justice & Disability (NCCJD)

MISSIONNCCJD will become the national focal point for the collection and dissemination of resources and serve as a bridge between justice and I/DD professionals. NCCJD will pursue and promote safety, fairness and justice for all people with intellectual and developmental disabilities as suspects, offenders, victims or witnesses.

More on Greenspan's model of personal competence: Relationship between IQ and social, practical, and conceptual abilities

I am pleased to see that, after a relatively long draught in published research, someone is again investigating the relations between general intelligence, and the primary domains of adaptive behavior, in models (that when examined closely) that are investigating aspects of Greenspan's' model of personal competence. The title, abstract, and key figure from this new research follow. The article can be read here. Kudos to these researchers

Click on images to enlarge





My primary criticism of this study is that it completely ignores the primary foundation research in this area that occurred between 1990 and 2000, some of which are the primary research studies cited in the AAIDD manuals to support the domains of practical, conceptual and social competence (Greenspan's model). I have provided a list of that research, and results from the most prominent article from that group of researchers, below.












Yes, my name is all over these MIA studies (in the current featured article) so some could see my comments as academic sour grapes for being overlooked. But I see their omission as a lack of scholarly rigor by the researchers and the journal who published the current article. All of the MIA studies can be found at the MindHub--scroll down until you see the list of studies shown above. Then click away and download and read. It would have been nice if the new study results would have been integrated with the extant personal competence research literature.

In the final analysis I am pleased that someone is conducting much needed research on these constructs given the pivotal role they play in the definition and assessment of MR/ID.

The most comprehensive synthesis of the Flynn effect (effect size) literature to date

Trahan et al. (2014) have just published the most comprehensive meta-analysis of the size of the Flynn effect (norm obsolescence) to date. This is seminal work adds significant credibility to the Flynn effect as a scientific fact. Link to article above. Click on image to enlarge the abstract. I promise that one of these days I will update the Flynn Effect Archive Project. I have many other articles to add.
