Our mind has many facets, and the top layer/ consciousness network only has to deal with what each lower network is current paying attention too/ focusing on. Your eyes are currently paying attention to this word in this sentence; guided by the overall task of reading this topic. Your opinion on my comment is formed by your top layer executive network pattern matching on previous experience/ opinions; based on information fed in by the lower networks attention salience.
