The cognitive process of visual perception is the same for most of us, but the resulting perceptions differ, as they are affected by other brain functions as well. Such influencing factors include our memory, in which we store information for personal, social and general problem-solving purposes. How we process new information depends greatly on our existing memories that, unconsciously, control this process. As a result, we unintentionally ignore aspects that at first don’t seem to be consistent with our self, and with that we limit our knowledge, and, on a social level, our collective knowledge. Memory, however, can be shaped, as it is inherently constructive, and by using its connection to perception, we may be able to modify it with visual techniques. A relevant medium for this is books, which reflect on the interactions between visual perception an memory from historical, formal and functional aspects.
