It was proposed that consciousness to result from quantum computations supported by nested well controlled oscillatory cortical activity, which may be disclosed by analysis of EEG activity. Oscillatory activity is easily entrained by external stimulation; e.g. periodic stimuli or well parsed verbal sound packs. These two concurrent cortical computations (e.g., click perception and language understanding) may share different degrees of entrainment, depending on stimulus properties and the nature of the task to be solved. This entrainment may promote interference between the concurrent conscious computations. The purpose of the present paper is to investigate this possible interference, by asking people to correlated click occurrence to the words being listened in order to force phase locking between cyclic cortical activity involved in click analysis and language decoding. EEG was recorded while volunteers solved the task. Results confirmed the computational cross taking errors because both text understanding impoverished and sensory perception errors increased as cortical activity entrainment enhanced. Event Related Analysis pointed to some EEG components that may be involved in the process.
