COI…I have a financial interest in the WJ IV as one of its authors.  Examination of differential effects of cognitive abilities on reading and mathematics achievement across race and ethnicity: Evidence with the WJ IV - ScienceDirect  https://ift.tt/EzAiwtO There has been little research investigating the predictive validity of modern  intelligence tests  for racially and ethnically diverse students. The validity of test score interpretation within educational and psychological assessment assumes that test scores predict educationally relevant phenomena equally well for individuals, regardless of group membership (American Educational Research Association et al., 2014; Messick, 1995; Warne et al., 2014). We used multiple group latent variable structural equation modeling (SEM) to investigate Cattell-Horn-Carroll general ( g ) and broad cognitive abilities on reading and mathematics achievement and whether these differed between racial (African American, Asian, ...

 Structure of working memory in children from 3 to 8 years old. - PsycNET  https://ift.tt/pw8xWyZ Abstract Several models of working memory (WM) have been proposed in the literature. Most of the research on the architecture of WM is based on adults or older children, but less is known about younger children. In this study, we tested various models of WM on a sample of 739 Italian children, ranging in age from 3 to 8 years, primarily of European heritage and from medium to medium–high socioeconomic background. Participants were assessed with 12 WM tasks, systematically varying the modality and level of executive control required (based on the number of activities to be performed at once: retention alone, ignoring distractors, and dealing with dual tasks). We examined younger children ( n  = 501,  M age  = 56.8 months,  SD  = 6.4, 48% boys) and older children ( n  = 238,  M age  = 80.0 months,  SD  = 9.0, 58% boys) separately...
