The Two-Stream Hypothesis, where object properties are processed independently from spatial information, remains the most well established theory of visual processing. However, it concerns me that most models that reference this theory stop at the end of the two streams; they never say how the mind translates those sources of information into action. Are there models and/or theories out there that try and situate the Two Streams of information into a full perception action cycle? And if not, then why not (e.g. complexity, better theories, different level of analysis, etc.)?
