Eye Movements and Perception.
Gaarder, Kenneth
An explanation of visual perception is presented using physiological facts, analogies to digital computers, and analogies to the structure of written languages. According to the explanation, visual input is discontinuous, with the discontinuities mediated by and correlated with the jumps of the eye. This is analogous to the gated and buffer-stored input of a digital computer and raises answerable questions as to how other sense-modalities are inputted--whether in series or parallel with visual input. Drawing analogies to other information-bearing systems, such as printed language, helps clarify certain issues. Just as printed language has a hierarchical structure with sets and elements of letters, words, and sentences (with the sizes of the sets increasing up the hierarchical scale), so in the brain there must be an analogous hierarchy, with nerve spikes as the lowest set and the "packages" of discontinuous visual input as a higher level. The establishment of a discontinuous input model, with lucid alternatives of intermodality processing, leads to a computer-analogy model of behavior as a hierarchically structured chain of states which define acts. Figures and references are given. (Author/DE)
