Dynamic attention enables object permanence

Dynamic attention helps us perceive objects as continuous across time despite their movements. Through indexing and target tracking, it exploits low-level features in order to infuse percepts with coherence, facilitating high-level processing. This is similar to how gaze stabilization and pupil reflexes reduce stimuli dimensionality early on. Target tracking in dynamic attention is similar to optic flow in computer vision. The limited sampling frequency of dynamic attention allows for the aliasing phenomenon.
