It is assumed that word-colour combinations and probabilities appeal to different levels of distractor effects. It was found that low probability of conflicting trials leads to significant reinforcement of Stroop effect and practical impossibility to train; high probability leads to its practical disappearance.}, annote = {The phenomenology of perceptive attention in stimulus-distractor derivation condition is analyzed.
