Two Independent Mechanisms for Motion-In-Depth Perception: Evidence from Individual Differences
Our forward-facing eyes allow us the advantage of binocular visual information: using the tiny differences between right and left eye views to learn about depth and location in three dimensions. Our visual systems also contain specialized mechanisms to detect motion-in-depth from binocular vision, but the nature of these mechanisms remains controversial. Binocular motion-in-depth perception cou...
متن کاملMotion parallax thresholds for unambiguous depth perception
The perception of unambiguous depth from motion parallax arises from the neural integration of retinal image motion and extra-retinal eye movement signals. It is only recently that these parameters have been articulated in the form of the motion/pursuit ratio. In the current study, we explored the lower limits of the parameter space in which observers could accurately perform near/far relative ...
متن کاملDepth perception in motion parallax and stereokinesis.
Perceived depth in the stereokinetic effect (SKE) illusion and in the monocular derivation of depth from motion parallax were compared. Motion parallax gradients of velocity can be decomposed into 2 components: object- and observer-relative transformations. SKE displays present only the object-relative component. Observers were asked to estimate the magnitude and near-far order of depth in moti...
متن کاملMotion Perception, Elementary Mechanisms
Visual motion is essential for many aspects of biological function, including rapidly detecting predators and prey, navigating through the visual environment, and constructing a three-dimensional visual representation from two-dimensional retinal input. However, motion information is not provided by the instantaneous retinal signal, but has to be computed from temporal variations in luminance o...
متن کاملNeural population models for perception of motion in depth
Changing disparity (CD) and interocular velocity difference (IOVD) are two possible mechanisms for stereomotion perception. We propose two neurally plausible models for the representation of motion-in-depth (MID) via the CD and IOVD mechanisms. These models create distributed representations of MID velocity as the responses from a population of neurons selective to different MID velocity. Estim...
