The D-KEFS Color-Word Interference test purports to measure the inhibition of an automatic verbal response while generating a conflicting response [1]. The measure is comprised of four conditions: the naming of color patches, the reading of words (red, blue, green) printed in black ink, the interference task (inhibit reading color words to name the ink colors in which the words are printed), and a measure of inhibition and cognitive flexibility (switch between naming the dissonant ink colors and reading the color words). The D-KEFS manual suggests that the fourth condition represents a greater cognitive challenge, and thereby requires a longer completion time, as reflected by the normative data. Patient performance, in the context of a neuropsychological battery administered on a stroke rehabilitation unit, was not consistent with the expected score pattern illustrated in the D-KEFS normative sample. This study seeks to explicate this variation and to elucidate the causality behind the pattern of performance observed on neuropsychological assessment in a stroke rehabilitation population.
