Abstract

In this joint study the phenomenon of “filling in” or “blind spot” is discussed, and arguments against the theories of Dennett on the same topic are provided. The central point of contention is whether the brain bridges the data gap to “fill in” the incomplete visual stimuli, or does it simply ignore the deficiency caused by the blind spot, as what Dennett, a noted cognitive scientist, believes. Several experiments in psychophysics are conducted to obtain a rich pool of objective data from which conclusions can be drawn. Related studies in neurophysiology, such as the Krauskopf, Gattass, and Gilbert effects, are also cited and discussed. In summary, this chapter's findings are as follows: the human brain has a means of interpolating visual stimuli; “filling in” can be visually represented by the brain; and that this visual representation probably involves the brain's capacity for interpolation.
