Norfolk, Philip A.; Farmer, Ryan L.; Floyd, Randy G.; Woods, Isaac L.; Hawkins, Haley K.; Irby, Sarah M. – Journal of Psychoeducational Assessment, 2015
The representativeness, recency, and size of norm samples strongly influence the accuracy of inferences drawn from their scores. Inadequate norm samples may lead to inflated or deflated scores for individuals and poorer prediction of developmental and academic outcomes. The purpose of this study was to apply Kranzler and Floyd's method for…

Andersen, Lori – Roeper Review, 2014
Visual-spatial ability is a multifaceted component of intelligence that has predictive validity for future achievement in science, technology, engineering, and mathematics (STEM) occupations. Although identification and development of STEM talent is a national priority, visual-spatial ability is rarely measured and relatively neglected in gifted…

Stuebing, Karla K.; Fletcher, Jack M.; Branum-Martin, Lee; Francis, David J. – School Psychology Review, 2012
This study used simulation techniques to evaluate the technical adequacy of three methods for the identification of specific learning disabilities via patterns of strengths and weaknesses in cognitive processing. Latent and observed data were generated and the decision-making process of each method was applied to assess concordance in…

Naglieri, Jack A. – School Psychology Review, 1999
Responds to Kranzler and Keith (this issue) by providing data from a data-driven approach that suggests the Cognitive Assessment System (CAS) has validity. Provides evidence that the interpretation of the planning, attention, simultaneous and successive (PASS Scales) theory described in the "CAS Interpretive Handbook" is well supported.…

Kranzler, John H.; Keith, Timothy Z. – School Psychology Review, 1999
Uses confirmatory factor analysis (CFA) to address unresolved issues concerning the structure of the Cognitive Assessment System, a test of intelligence based upon the planning, attention, and simultaneous-successive (PASS) processes theory of human cognition. Results reveal that the CFA of the standardization data do not support use of the CAS…

Daley, Christine E.; Nagle, Richard J.; Onwuegbuzie, Anthony J. – 1997
The cognitive styles of 40 children (ages 8-17) with serious emotional disturbance (SED) were investigated via their performance on Planning-Attention-Simultaneous-Successive (PASS) model tasks as represented by the Das-Naglieri Cognitive Assessment System (CAS). In the study, the children with SED and 40 typical children were administered the 14…
