Change Blindness After investigating spatial cognition and the construction of cognitive maps in my previous paper, Where Am I Going? Where Have I Been Spatial Cognition and Navigation, and growing in my comprehension of the more complex elements of the nervous system, the development of an informed word of human perception has become possible. The formation of cognitive maps, which serve as internal representations of the human being, are dependent upon the human capacities for resource and visual perception (1). The objects introduced into the theatre of vision are translated into electrical messages, which activate the neurons of the retina. The resultant retinal message is organized into several forms of sensation and is transmitted to the brain so that neural representations of presumption surroundings may be recorded as memory (2). I suggested in my previous paper that these neural representations must be maintained and increasingly updated with each successive varieg ate in environment and movement of the eye. Furthermore, I claimed that this information moulding produces a constant, stable experience of a dynamic, external world (1). However, myriad studies and the testimony of any motorist who has had the unfortunate experience of hitting an unseen object, contradict the universality of that claim and illuminate a startling veracity human beings do not always see those objects presented in their visual field nor alterations in an observed scene (3,4,5,6,7,8,9). The failure to consciously witness change when distracted for mere milliseconds by saccade or artificial blink events is referred to as change blindness. In order to comprehend this phenomenon, the physical act of looking and the process of seeing must be diffe... ...47/print5)Cognet, a site on Cognition http//cognet.mit.edu/perspective/item.tcl?msg_id=00005N6)Memory For centrally attended changing objects in an incidental really world change, An article by Levin, Simons, Angelone, and Chabris http//wjg.harvard.edu/cfc/Levin2002.pdf7) Scott-Brown, K.C. & Orbach, H.S.
