Computational theory and cognition in representational momentum and related types of displacement: A reply to Kerzel

Abstract

Kerzel's (2006) commentary on Hubbard's (2005) review of the literature on representational momentum and related types of displacement highlights differences of interpretation between Hubbard and Kerzel, but also contains mischaracterizations of Hubbard's position. In this reply to Kerzel, these differences and mischaracterizations are addressed. Issues are briefly considered that involve the following: whether displacement involves multiple processes; the Marr (1982) framework; the relationship of displacement to internalized physics, goodness of perceived motion, apparent motion, and oculomotor overshoot; generalization from flashed objects to moving objects; necessary and sufficient criteria for displacement; and whether the existence of auditory representational momentum provides evidence for a supramodal account of displacement.
