Abstract. Nonverbal Stroop tasks produce results that parallel those found with the color-word Stroop task (Koch & Roid, 2012) yet the question remains whether verbal and nonverbal Stroop tasks measure the same cognitive process. Two nonverbal Stroop tasks, one color-word Stroop task, and a continuous performance test were administered to determine the degree to which nonverbal tasks are related to each other, to the color-word Stroop task, and to other attentional processes. Results indicate that all three Stroop tasks produce interference but that nonverbal Stroop tasks may reflect a different underlying cognitive process than associated with the color-word Stroop task.
