Abstract: 1. Introduction: The Inadequacy of Visual Modules
This article discusses some implications for understanding vision of recent theoretical results concerning the neural architectures that subserve visual perception in humans and other mammals (Cohen and Grossberg 1984; Grossberg 1984, 1987a, 1987b, 1988; Grossberg and Marshall 1989; Grossberg and Mingolla 1985a, 1985b, 1987; Grossberg, Mingolla, and Todorovid 1989; Grossberg and Rudd 1989; Grossberg and Todorovid 1988). In addition, a new result is stated concerning differences between the neural mechanisms for perception of static visual forms and moving visual forms, indeed why both types of mechanisms exist.
These results contribute to the development of a neural theory of preattentive vision, called FACADE Theory. FACADE Theory clarifies that, whereas specialization of function surely exists during visual perception, it is not the type of specialization that may adequately be described by separate neural modules for the processing (say) of edges, textures, shading, stereo, and color information. In particular, the present theory provides an explanation of many data that do not support the modular approach described by Marr (1982).
