It appears that a component of verbal reaction time, response-choice latency, exists for encoded words as well as colors. Therefore, it was hypothesized that color stimuli could exert a disruptive influence on the processes of this latency to encoded word stimuli in contrast to the reverse effect which has often been found in the standard Stroop test. Stroop-like interference in word reading was produced by preexposure of color names printed in colored ink, followed by the presentation of a second stimulus which reinforced the color information of the first stimulus. The experimental results do not appear to be an artifact of mere distraction of attention.
