Words interact with colors in a globally aphasic patient: evidence from a Stroop-like task.
Stroop-like manual reaction time tasks were administered to 16 controls and one globally aphasic patient who was unable to match written color words with the corresponding color. Although the patient could not explicitly access the meaning of written color words, he showed a similar pattern of performance in the reaction time tasks as the controls: written words were processed automatically and they interacted with the processing of the color of the letters. Thus, the results of this study suggested that it is possible to process unrecognized words implicitly to a cross-domain semantic level where the processing of words interacts with the processing of colors. The results from this and other studies on implicit language processing indicate that linguistic stimuli can be analysed to relatively high levels without any awareness.
