Reverse stroop effects with untranslated responses.

Translation accounts have argued that the presence of a Stroop effect in the context of a nonvocal untranslated response is caused by verbal mediation. In its simplest form, color-labeled buttons are translated into a verbal code that interferes with color responses. On this logic, in the reverse Stroop task (identify the word; ignore the color), responses made via word-labeled buttons should also be verbally mediated. Thus, no reverse Stroop effect (RSE) should be seen. The authors tested this verbal mediation hypothesis in 4 reverse Stroop task experiments. An RSE was observed across 4 experiments. The results of Experiments 3 and 4 suggest that this RSE is driven by response competition. It is argued that the data from these 4 experiments are inconsistent with unadorned translation accounts of the RSE but consistent with an account in which the strength of association between a stimulus and a specific response plays a major role.

When the visual format of the color carrier word does and does not modulate the stroop effect.

We investigated the impact of making the color carrier word visually unfamiliar via case and font mixInG in the context of three Stroop experiments. Experiment 1 yielded an increase in the size of the Stroop effect when the color carrier words were visually unfamiliar relative to lowercase words that were case and font consistent. Experiments 2A and 2B showed that the modulation of the Stroop effect by visual familiarity observed in Experiment 1 was eliminated when there was no correlation between the color and the color carrier word. These results are considered in the light of four different theoretical accounts of the Stroop effect (strength of association [Cohen, Dunbar, & McClelland, 19901, instance [Logan, 1988], schema [MacLeod, 2000], and obligatory processing followed by deactivation [Coltheart, Woollams, Kinoshita, & Perry, 1999]). None of these accounts appear capable of explaining all the results.
