Abstract : Portable computerized cognitive assessment batteries provide a method of assessing cognitive performance during real life exposure to demanding situations. The present study evaluated the effect of relaxing guidelines regarding pre-testing to achieve valid assessments in repeated measures studies. Data reported by Kennedy et al. (1985) were reanalyzed using structural equation modeling procedures. The findings demonstrated that 7 of 9 commonly used cognitive tests could be interpreted as valid measures the first trial onward. This conclusion also may apply to Sternberg's (1966) memory test if an arguably chance finding of a change in true score variance on a single trial fails to replicate. Baddeley's (1968) Grammatical Reasoning test required a two-dimensional model to represent the data. The results for two tests (Code Substitution and Manikin) were replicated with data from other published sources. If these initial results replicate on further study, the cognitive measures examined can be used in research designs such as simple pre-post and experimental-control group research designs even when no practice sessions are feasible.
