Convergence function in binocular visual space. I. A note on theory.

Abstract

A review and elucidation of the theory of the convergence function is presented here. In this connection, certain phenomenal aspects of binocular visual experience are noted; it is felt that any general theory must take cognizance of them. In particular, the Luneburg theory of the alley experiments is discussed in some detail, and an attempt is made to highlight the underlying and possibly equivocal assumptions. In emphasizing the distinction between pure mathematical postulates and pure phenomenal experience, we have hoped both to clarify those points at which arbitrary decisions may legitimately enter into the theory (e.g., the normalization), and to set the stage for deliberate experimentation.
