variety Blindness After investigating spatial recognition and the construction of cognitive maps in my previous paper, Where Am I dismissal? 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 discussion of human apprehension has become possible. The formation of cognitive maps, which serve as internal representations of the world, are dependent upon the human capacities for vision and visual perception (1). The objects introduced into the field of vision are translated into electrical messages, which activate the neurons of the retina. The resultant retinene message is organized into several forms of sensation and is transmitted to the brain so that neural representations of given surroundings may be recorded as memory (2). I suggested in my previous paper that these neural representations must be maintained and progressively updated with each successive con vert in environment and movement of the eye. Furthermore, I claimed that this information treating produces a constant, enduring experience of a dynamic, external world (1).
