Best, John R.; Miller, Patricia H.; Naglieri, Jack A. – Learning and Individual Differences, 2011
This study examined age-related changes in complex executive function (EF) in a large, representative sample (N=2036) aged 5 to 17 using the Cognitive Assessment System (CAS; Naglieri & Das, 1997a). Relations between complex EF and academic achievement were examined on a sub-sample (N = 1395) given the Woodcock-Johnson Tests of…

Floyd, Randy; Meisinger, Elizabeth; Gregg, Noel; Keith, Timothy – Psychology in the Schools, 2012
The purpose of this research was to investigate the cognitive abilities that explain reading comprehension across childhood and early adulthood. Drawing from the standardization sample of the Woodcock-Johnson III, analyses were conducted with large samples at age levels spanning early childhood to early adulthood: 5 to 6 (n = 639), 7 to 8 (n =…

Diamantopoulou, Sofia; Pina, Violeta; Valero-Garcia, Ana V.; Gonzalez-Salinas, Carmen; Fuentes, Luis J. – Journal of Psychoeducational Assessment, 2012
This study validated the four mathematics tests of the Spanish version of the Woodcock-Johnson III (WJ-III) Achievement (ACH) battery for use in the first six grades of school in Spain. Developmental effects and gender differences were also examined. Participants were a normal population sample of 424 (216 boys) children aged 6 to 13 years.…

Preschool Executive Control on the Shape School Task: Measurement Considerations and Utility
Peer reviewed Peer reviewed

Pritchard, Verena E.; Woodward, Lianne J. – Psychological Assessment, 2011
Executive functions (EF) necessary for purposeful goal-directed activities undergo rapid change and development during the preschool years. However, of the few psychometrically valid measures of EF suitable for use with preschoolers, information on task sensitivity and predictive validity is scant. The neurodevelopmental correlates of early…

Nonlinear Growth Models in M"plus" and SAS
Peer reviewed Peer reviewed
Direct linkDirect link
Grimm, Kevin J.; Ram, Nilam – Structural Equation Modeling: A Multidisciplinary Journal, 2009
Nonlinear growth curves or growth curves that follow a specified nonlinear function in time enable researchers to model complex developmental patterns with parameters that are easily interpretable. In this article we describe how a variety of sigmoid curves can be fit using the M"plus" structural modeling program and the nonlinear…
