Motion parallax is computed in the updating of human spatial memory.
As we move through space, stationary objects around us show motion parallax: their directions relative to us change at different rates, depending on their distance. Does the brain incorporate parallax when it updates its stored representations of space? We had subjects fixate a distant target and then we flashed lights, at different distances, onto the retinal periphery. Subjects translated sid...
متن کاملUpdating Human Spatial Memory
Humans have developed different ways to represent spatial information, both in memory and in off-line formats, such as maps and spatial descriptions. These representational systems have developed to deal with environment complexity, the many goals one might have within an environment, and the changes that occur both within the environment and pertaining to how it is used. The present chapter di...
متن کاملMotion Parallax is Asymptotic to Binocular Disparity
Researchers such as (Rogers & Graham, 1982) have noticed "similarities between motion parallax and stereopsis" but have not previously shown the precise mathematical relation between them. In this article we show that retinal motion from lateral translation is asymptotic to a ...
متن کاملSpatial frequency tuning for 3-D corrugations from motion parallax
We provide evidence for the existence of multiple channels tuned to the spatial frequency of depth modulations defined by motion parallax. By linking the distortion of a random dot pattern to the horizontal position of an observer's head horizontally oriented 3-D corrugations were simulated in which the depth function consisted of a range of frequencies. In a baseline experiment thresholds were...
متن کاملAbsence of spatial updating when the visuomotor system is unsure about stimulus motion.
How does the visuomotor system decide whether a target is moving or stationary in space or whether it moves relative to the eyes or head? A visual flash during a rapid eye-head gaze shift produces a brief visual streak on the retina that could provide information about target motion, when appropriately combined with eye and head self-motion signals. Indeed, double-step experiments have demonstr...
