Acting on What You are Perceiving: The Two-Visual-Systems Hypothesis Revisited
Two-Visual-Systems Hypothesis Revisited
Abstract
The two-visual-systems hypothesis proposed by Goodale and Milner is a radical one. If it were to be true, then our common sense such as we are acting on what we are perceiving should be completely abandoned. In this paper, I argue that the hypothesis over-generalizes what happens in simple tasks to what happens in complex tasks. By contrast, I demonstrate that what happens in complex tasks is compatible with our common sense. In a word, though what we are acting on may come apart from what we are perceiving in some cases, that is not the whole story.
