THE INFLUENCE OF UNCONSCIOUS RHYTHMIC STI MULATION ON COGNITIVE ACTIVITY

The influence of unconscious rhythmic (10 Hz) visual stimuli (emotiona lly. <<neutral>> words) on their subsequent identification among other s were studied. The quality of performance significantly increased whe n unconscious stimuli coincided with negative phase of EEG-rhythm deli berately induced by light flashing. While exposing the unconscious sti muli during unstable spontaneous EEG-rhythm this effect was less prono unced. A conclusion can be made that unconscious rhythmic stimulation coinciding with negative imposed EEG-rhythm can have a pronounced modu lating affect on.subsequent cognitive activity.
