While the mere recognition of a word is occurring unconsciously, the meaning of that word is being accessed at much higher levels in the brain without our being aware of it. Other aspects of the word can also be computed unconsciously, such as its sound, or its emotional content, or whether we spoke it in error and want to catch the error. Similarly, when we see a number, we effortlessly tap into the mathematical systems of our brain. Scientists are still struggling to understand how unconscious processing works and how deep it can go.
