It has long been known that naming the color of a color word leads to what is known as the Stroop
effect (Stroop, 1935). In the traditional Stroop task, when compared to naming the color of a
color-neutral stimulus (e.g. an X or color patch), the presence of an incongruent color word
decreases performance (Stroop interference), and a congruent color word increases performance
(Stroop facilitation). Research has also shown that auditory color words can impact the color
naming performance of colored items in a similar way in a variation known as cross-modal Stroop
(Cowan & Barron, 1987). However, whether the item that is colored interacts with the auditory
distractor to affect cross-modal Stroop interference is unclear. Research with the traditional, visual
Stroop task has suggested that the amount of color the visual item displays and the semantic and
phonetic components of the colored word can affect the magnitude of the resulting Stroop
interference; as such, it is possible the same components could play a role in cross-modal Stroop
interference. We conducted two experiments to examine the impact of the composition of the
colored visual item on cross-modal Stroop interference. However, across two different
experiments, three test versions, and numerous sets of trials, we were only able to find a small
effect of the visual stimulus. This finding suggests that while the impact of the auditory stimuli is
consistent and robust, the influence of non-word visual stimuli is quite small and unreliable and,
while occasionally being statistically significant, it is not practically so.
