Document Summary
Consciousness is, according to the dictionary, the subjective experience of perceiving oneself and one"s surroundings. Researchers use this definition: if a cooperative person reports being conscious (aware) of one stimulus and not of another, then he or she was conscious of the first and not the second. Methods of presenting a stimulus so that people are conscious of it sometimes and not others: Masking = a word or other stimulus appears on the screen for a fraction of a second, preceded and/or followed by an interfering stimulus. Backward masking = if the interfering stimulus follows it but doesn"t precede it. Flash suppression = flash dots on and off rapidly so that you lose sight of one and not the other. Binocular rivalry = the alternation between seeing the pattern in the left retina and the pattern in the right retina. The brain notices that something in meaningful or important even before you become conscious of it.
