AAIDD/ARC SCOTUS 2015 amicus brief regarding Texas adaptive behavior issues (Briseno factors)
An amicus brief (click to access) has been filed with SCOTUS by AAIDD and ARC regarding a petition for writ of certiorari for a case in Texas (Lizcano). Briefly, the amicus brief points out the problems with the Texas Briseno factors (click here for all prior Briseno related posts) in the evaluation of prong 2 of the Dx of ID (adaptive behavior). The problems at issue address the most basic principles of scientific reliability and validity in the evaluation of the adaptive behavior prong of the ID definition

Law Review Article: Dr. James Ellis on Hall v Florida (SCOTUS, 2014)--ID is a condition-not a number
Dr. James Ellis has presented a nice summary of the major change in the determination of ID in Atkins cases as a result of the Hall v Florida 2014 SCOTUS decision. The main point is summarized by the statement that ID is a "condition" and "not a number." Scientific and professional evidence and clinical judgement must be involved in the determination--no longer can "bright line" IQ cut-off scores be used in isolation. Click here to read the article.

New favorable Atkins SCOTUS decision: Brumfield v Cain
From SCOTUS blog.
- Holding: Because the inmate’s evidence of intellectual disability satisfied the requirements of 28 U.S.C. § 2254(d)(2), he was entitled to have his claim based on Atkins v. Virginia, in which the Court held that the Constitution prohibits the execution of the mentally disabled, considered on the merits in federal court.
- Judgment: Reversed and remanded, 5-4, in an opinion by Justice Sotomayor on June 18, 2015. Justice Thomas filed a dissenting opinion in all but Part I-C, of which Chief Justice Roberts, Justice Scalia, and Justice Alito joined. Justice Alito filed a dissenting opinion, in which Chief Justice Roberts joined.

WAIS-IV US/Canadian norms controversy---articles for readers to review
I previously provided an FYI post on a hot topic in Canada...claims that the new WAIS-IV Canadian norms were flawed. There are now three articles outlining the different arguments. The three articles, published in JPA, can be found here, here, and here.
I continue to not comment on this controversy given my obvious conflict of interest as a coauthor of the competing WJ-IV.

Another Flynn effect (norm obsolescence) meta-analysis
A second massive meta-analysis of the Flynn effect (norm obsolescence) was recently published (Pietschnig & Voraseck, 2015). The study investigated different Flynn effect ability domain effects (by Gf, Gc, Gv), and other moderating variables. However, the most important conclusion is that the authors conclude that the 3 IQ points per decade rule-of-thumb appears to be the best estimate of the FE on global IQ scores. This conclusion is consistent with the Trahan et al. (2014) meta-analysis and the recent AAIDD recommendation.
AAIDD chapters on intellectual functioning and the Flynn effect - overdue post
It has been along time since I've been able to devote time to any of my three professional blogs. I have been unbelievably busy with travel and professional presentations. In fact, I have been so busy that I failed to feature two of my own recent Atkin's death penalty related book chapters that appeared in the new AAIDD book "Determining Intellectual Disability in the courts: Focus on capital cases." I have made these two chapters available via the MindHub web portal but do not believe I featured them at this blog (or at IQ's Corner). One chapter deals with assessment of intellectual functioning issues and the other IQ test norm obsolescence (aka., the Flynn Effect). The references (with links) are below.

Florida Supreme Court Strikes Down Mentally Ill Defendant's Death Sentence as Disproportionate [feedly]

Florida Supreme Court Strikes Down Mentally Ill Defendant's Death Sentence as Disproportionate
// Death Penalty Information Center
In a case spotlighting issues of mental illness and the death penalty, the Florida Supreme Court on April 23 unanimously overturned the death sentence imposed on a severely mentally ill death-row inmate, Humberto Delgado (pictured). Delgado, who was convicted of killing a Tampa police officer, will be resentenced to life without parole. The court said, "We do not downplay the fact that Corporal Roberts lost his life as a result of Delgado's actions. However … we are compelled to reduce Delgado's sentence to life imprisonment because death is not a proportionate penalty when compared to other cases." Delgado had a history of delusions and psychotic behavior before the crime, including believing that police were out to kill him and that people were following him and sitting in trees outside his home. Delgado's attorneys pointed out that, because Delgado shot the police officer only after the officer had used a Taser, there was a lack of premeditation. Tampa police Chief Jane Castor released a statement in response to the decision, saying, "We respect the justice system and those who have to make tough decisions. Regardless of the conclusion, it doesn't bring Mike back and it doesn't relieve the pain that his wife, son and his TPD family feel. His life sentence will still ensure he is held accountable for his actions."
