Abstract
Executive functions (EFs) refer to a range of cognitive control and regulation processes that coordinate thoughts and actions in a goal-directed way and are regarded as a hallmark of intellectual abilities. However, most studies have used a single measurement to explore the relationship between EFs and intelligence, and there is a lack of robust evidence to demonstrate the link between EF-related neural substrates and intelligence under an integrative framework. To address this issue, we employed a large sample (primary dataset, n = 881; hold-out dataset, n = 181) from the Human Connectome Project, which included high-quality MRI data and multiple EF and intelligence measurements. Based on a machine learning framework, we examined the predictive effect of EF-related functional connectivity(FC) on fluid intelligence (Gf) and crystallized intelligence (Gc) using a connectome-based predictive model. The results showed that all types of EF-related FCs (i.e., EF-common, updating-, shifting-, and inhibition-specific FCs) predicted novel subjects' Gf and Gc in the primary dataset and successfully generalized to the hold-out dataset. Additionally, EF-related FCs appeared to demonstrate better performance in predicting Gc. Identified predictive FCs revealed the domain-general and domain-specific connectivity patterns of EFs, and the network hubs were mainly located in the default mode, cognitive control, salience, and visual networks. These findings facilitate our understanding of the relation between multiple EF domains and intelligence from the perspective of network neuroscience, suggesting that different intellectual abilities and EFs share similar neural bases to some extent, which allows the link between EFs and intelligence to be revisited.

The structure of working memory during childhood: a systematic review: Journal of Cognitive Psychology: Vol 0, No 0

https://www.tandfonline.com/doi/full/10.1080/20445911.2021.1887199

ABSTRACT
There are many working memory (WM) models, generally formulated and developed in adults. Controversies arise as to whether such models are adequate conceptualizations of WM in children. The aim of the present study is to perform a systematic review of studies that evaluate the structure of WM during childhood. Databases (PubMed, Scopus) and article reference lists were reviewed, identifying 264 studies and including 14 in the review. These include participants between 4 and 15 years of age, with typical development, and they evaluated the structure of WM using confirmatory factor analysis. Results show that from 4 to 6 years onwards a structure composed of a domain-general executive component together with two domain-specific storage components (verbal, visuospatial) is identified, generally being the best fitting model. Limitations and potential contributions of the reported results are discussed.

Long-term stability of Wechsler Intelligence Scale for Children–fifth edition scores in a clinical sample: Applied Neuropsychology: Child: Vol 0, No 0

 Long-term stability of Wechsler Intelligence Scale for Children–fifth edition scores in a clinical sample: Applied Neuropsychology: Child: Vol 0, No 0 
https://www.tandfonline.com/doi/abs/10.1080/21622965.2021.1875827

Abstract
This study investigated the stability of Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V) scores for 225 children and adolescents from an outpatient neuropsychological clinic across, on average, a 2.6 year test-retest interval. WISC-V mean scores were relatively constant but subtest stability score coefficients were all below 0.80 (M = 0.66) and only the Verbal Comprehension Index (VCI), Visual Spatial Index (VSI), and omnibus Full Scale IQ (FSIQ) stability coefficients exceeded 0.80. Neither intraindividual subtest difference scores nor intraindividual composite difference scores were stable across time (M = 0.26 and 0.36, respectively). Rare and unusual subtest and composite score differences as well as subtest and index scatter at initial testing were unlikely to be repeated at retest (kappa = 0.03 to 0.49). It was concluded that VCI, VSI, and FSIQ scores might be sufficiently stable to support normative comparisons but that none of the intraindividual (i.e. idiographic, ipsative, or person-relative) measures were stable enough for confident clinical decision making.

Abstract

 The community  of educational measurement researchers and practitioners has made many positive contributions to education, but has also become complacent and lost the public trust. In this article, reasons for the lack of public trust in educational testing are described, and core values for educational measurement are proposed. Reasons for distrust of educational measurement include hypocritical practices that conflict with our professional standards, a biased and selected presentation of the history of testing, and inattention to social problems associated with educational measurement. The five core values proposed to help educational measurement serve education are: (a) everyone is capable of learning; (b) there are no differences in the capacity to learn across groups defined by race, ethnicity, or sex; (c) all educational tests are fallible to some degree; (d) educational tests can provide valuable information to improve student learning and certify competence; and (e) all uses of educational test scores must be sufficiently justified by validity evidence. The importance of these core values for improving the science and practice of educational measurement to benefit society is discussed.

Abstract
Differentiation hypotheses concern changes in the structural organization of cognitive abilities that depend on the level of general intelligence (ability differentiation) or age (developmental differentiation). Part 1 of this article presents a review of the literature on ability and developmental differentiation effects in children, revealing the need for studies that examine both effects simultaneously in this age group with appropriate statistical methods. Part 2 presents an empirical study in which nonlinear factor analytic models were applied to the standardization sample (N= 2,619 German elementary schoolchildren; 48% female; age: M = 8.8 years, SD = 1.2, range 6–12 years) of the THINK 1–4 intelligence test to investigate ability differentiation, developmental differentiation, and their interaction. The sample was nationally representative regarding age, gender, urbanization, and geographic location of residence but not regarding parents' education and migration background (overrepresentation of children with more educated parents, underrepresentation of children with migration background). The results showed no consistent evidence for the presence of differentiation effects or their interaction. Instead, different patterns were observed for figural, numerical, and verbal reasoning. Implications for the construction of intelligence tests, the assessment of intelligence in children, and for theories of cognitive development are discussed.

Education and training guidelines for psychological assessment in health service psychology. - PsycNET

https://psycnet-apa-org.ezp2.lib.umn.edu/record/2020-85072-001

Abstract 

While recent survey findings suggest graduate programs in health service psychology (HSP) are allocating the same or increased time to education and training in psychological assessment over the last two decades, there is a lack of clear guidance for programs to implement practices associated with quality education and training. These Guidelines (found in full at https://www .apa.org/about/policy/guidelines-assessment-health-service.pdf) were developed to address this critical need. Developed by a task force of the American Psychological Association Board of Educational Affairs in 2018 and 2019, the Guidelines serve to inform faculty/supervisors, students, and the public as to quality practices associated with graduate education and training in psychological assessment. They are organized around seven domains: theory; psychological assessment process; psychometrics; tests and methods; ethics, legal issues, and professionalism; diversity; and supervision. These domains are drawn from a review of the scholarly literature on psychological assessment, as well as graduate psychology education and training. The domains and their associated Guidelines are interdependent, and, while some overlap exists among them, they should be considered in their entirety. While a summary of each section is provided in the present article, the full explanation of each domain is presented in the actual Guidelines document.
