The Event Structure of Motion Perceptionisely, that the planning component of intended actions influence processing of time critical motion. To make our argument, we first discuss action-perception interactions as well as time-to-contact (TTC) judgments. Then we present some experimental evidence.

Multiple Cortical Representations of Optic Flow Processingg or contracting visual fields projected on the retina. Gibson (1950) called this particular motion, originated by the observer’s own navigation, “Optic Flow”. He noted that when an observer moves forward, fixating his or her final destination, the expanding visual field seems to originate from a sp

A Visual Mechanism for Extraction of Heading Information in Complex Flow Fields objects move in characteristic ways away from or towards a focus of expansion or contraction (Gibson, 1950, 1954). For straight motion without eye or head movements, the flow pattern is radial with a speed gradient and complete symmetry (Gibson, 1950). It is then straightforward to compute the head

For example, visual acuity begins to deteriorate when retinal image speeds exceed a few degrees per second (Westheimer & McKee, 1975). There are a number of visual reflexes that help to stabilize our gaze on particular objects of interest by generating eye moveme
