AbstractMemory for the position of a moving target is often displaced in the&#xD; direction of anticipated motion, and this has been referred to as&#xD; representational momentum. Such displacement might aid spatial&#xD; localization by bridging the gap between perception and action, and might&#xD; reflect a second-order isomorphism between subjective consequences of&#xD; environmentally invariant physical principles and the functional architecture&#xD; of mental representation that can be modulated by an observers&#xD; expectations (e.g., that a moving target will change its heading) or by the&#xD; presence of nontarget stimuli (e.g., landmarks). Representational&#xD; momentum and related types of displacement reflect properties of the world&#xD; and properties of mental representation, and so a consideration of&#xD; representational momentum and related types of displacement contribute an&#xD; important component of contemporary psychophysics, and also broaden the&#xD; reach of psychophysics to include numerous topics not usually considered&#xD; within psychophysics (e.g., naive physics, boundary extension, flash-lag&#xD; effect, aesthetics, mental imagery).
