Quantifying the linguistic demands of the oral directions of preschool cognitive assessments


Research has indicated that school aged (6–16 years) versions of cognitive assessment instruments have varying levels of linguistic demand, which could impact assessment results for placement purposes. However, a significant limitation to this research is the fact that it has not been replicated with cognitive assessment instruments used in preschool populations. As such, the purpose of this study is to address this gap in the research literature by examining linguistic demands of cognitive test batteries used for preschool aged children. The Kaufman Assessment Battery for Children, Second Edition (KABC-II), Woodcock Johnson Test of Cognitive Abilities Fourth Edition (WJ Cog-IV), and the Wechsler Preschool and Primary Scale of Intelligence Fourth Edition were used for this examination. Overall results demonstrated that the oral directions of preschool assessments have relatively low linguistic demands. However, several subtests on WJ Cog-IV have high Complexity, Verbosity, and Total Demand indices, which can pose difficulty for students with limited word knowledge. Furthermore, the KABC-II was the least demanding assessment from a linguistic standpoint. Implications are discussed in terms of the assessment of early childhood populations. (author abstract)
