The aim of the presented studies was to verify whether few existing implicit rules can compete for resources responsible for their functioning. Two experiments were conducted using dual task in AGL paradigm. The competing rule was introduced using different senses: for Study 1 it involved visual stimuli, for Study 2 – haptic stimuli. The results of the two experiments indicate that the presence of the concurrent rule does not impair effectiveness of subjects, but it affects decision-making strategies. It turned out that two on-going implicit processes compete for resources, which leads to more confirmatory strategy. The effect was observed regardless of the sensory channel of the second rule. It may mean that implicit processes share a common, nonspecific pool of cognitive resources.
