Paul (2018a, 2018b) discussed the concept of critical thinking in a series of "American Annals of the Deaf" editorials examining how critical thinking might serve as a "springboard" to deep knowledge or wisdom and wondering if critical thinking should be viewed as a noble endeavor or hopeless cause. Paul explored three questions in which he considered (a) types of critical thinkers, (b) teaching and evaluating critical thinking, and (c) empathy's role in critical thinking. Responding to Paul, the author focuses on the same questions by summarizing Paul's view, then following with his own. He also explores the question "What is critical thinking?" Mostly, the author's views resemble Paul's, but he elaborates on places where he thinks gaps or possible misunderstandings exist. The author concludes that critical thinking is indeed a noble endeavor because it is not just what you think that matters, but how you think.

Experts frequently assess competency in criminal settings where the rate of feigning cognitive deficit is demonstrably elevated. We describe the construction and validation of the Denney Competency Related Test (D-CRT) to assess feigned incompetency of defendants in the criminal adjudicative setting. It was expected the D-CRT would prove effective at identifying feigned incompetence based on its two alternative, forced-choice and performance curve characteristics. Development and validation of the D-CRT occurred in described phases. Items were developed to measure competency based upon expert review. Item analysis and adjustments were completed with 304 young teenage volunteers to obtain a proper spread of item difficulty in preparation for eventual performance curve analysis (PCA). Test-retest reliability was assessed with 44 adult community volunteers. Validation included an analog simulation design with 101 jail detainees using MacArthur Competency Assessment Test-Criminal Adjudication and Word Memory Test as criterion measures. Effects of racial/ethnic demographic differences were examined in a separate study of 208 undergraduate volunteers. D-CRT specificity was identified with 46 elderly clinic referrals diagnosed with mild cognitive impairment and dementia. Item development, adjustment, and repeat analysis resulted in item probabilities evenly spread from.28 to 1.0. Test-retest correlation was good (.83). Internal consistency of items was excellent (KR-20 >.91). D-CRT demonstrated convergent validity in regard to measuring competency related information and as well as malingering. The test successfully differentiated between jail inmates asked to perforfm their best and inmates asked to simulate incompetency (AUC =.945). There were no statistically significant differences found in performance across racial/ethnic backgrounds. D-CRT specificity remained excellent among elderly clinic referrals with significant cognitive compromise at the recommended total score cutoff. D-CRT is an effective measure of feigned criminal incompetency in the context of potential cognitive deficiency, and PCA is assistive in the determination. Additional validation using knowns groups designs with various mental health-related conditions are needed. [ABSTRACT FROM AUTHOR]

Glycogen storage disease (GSD) type 1a is an inherited autosomal recessive metabolic disease caused by a deficiency in glucose-6-phosphatase activity. The objectives of this research were to systematically review the published literature on the epidemiology of GSD 1a and to assess the performance of reported epidemiology measures in a simulation model. In this systematic literature review 2,539 record titles and abstracts were screened. Of these, only 11 studies contained relevant data on GSD 1a disease epidemiology. Reported disease frequency ranged from 0.085/100,000 to 10.3/100,000 newborns when considering all the GSD literature. When this was narrowed to GSD 1 and GSD 1a, the range was tightened to 0.25–3.02/100,000 and 0.085–4.9/100,000 newborns, respectively. Most of the identified studies counted the number of diagnoses in a defined period and related to the number of births in the same (Dx method) or different time period (DoB method). The simulation model results indicate that in most of the situations, the Dx method provides a closer estimate to the true disease incidence than the DoB method. Despite the scarcity of epidemiology data, the results of this systematic review strongly support that GSD 1a and its parent disease groups (GSD and GSD 1) are rare diseases. [ABSTRACT FROM AUTHOR]
