Separate response time measures were obtained for input and output processes in order to determine their relative contribution to Stroop task interference. In Experiment 1 the amount of relevant and irrelevant stimulus information was varied in a Stroop task using a key press response. Experiment II compares the input and output times for color and word identification versions of Stroop tasks while varying the labeling of the response panel. Stroop interference was found to occur in both input and output time measures in both experiments. The results were interpreted as indicating both a perceptual and a response competition basis for Stroop interference. Author
