In a Stroop task, increasing the number of congruent trials in an experiment has no effect on reaction time for incongruent trials because the Stroop effect is caused by the interference between the automatic reading of the word and the manual response to the color. The more congruent trials there are, the more the automatic reading of the word is reinforced, and the more difficult it becomes to inhibit the automatic response to the color. This leads to a longer reaction time for incongruent trials.
