The purpose of this chapter is to review and evaluate a selected sample the empirical psychophysical literature relevant to the form recognition task. My goal is not only to determine what these articles are purported to say but also to continue to explore the conceptual and factual limits of what these findings can say. Some of the issues raised here are fundamental to understanding the limits of psychological experimentation to assay mental processes. Therefore, it is not possible to overemphasize the importance of such an inquiry throughout psychological science. Even a cursory adherence to behaviorism suggests that, all-too-often, well-established limits of inference and hypothesis have been violated in an exuberant and overenthusiastic search for answers to the unanswerable. Perception in general, and form recognition, in particular, must face these issues if the long-term viability of the science is to be assured.
