Path perception and Filehne illusion compared: model and data
Pursuit eye movements introduce retinal motion that complicates the recovery of self-motion from retinal flow. An extra-retinal, eye-velocity signal could be used to aid estimation of the observer's path, perhaps by converting retino-centric into head-centric motion. This conversion is apparently not precise because we often misperceive head-centric object velocity: in the Filehne illusion, for...
متن کاملExtraretinal and retinal amplitude and phase errors during Filehne illusion and path perception.
Pursuit eye movements give rise to retinal motion. To judge stimulus motion relative to the head, the visual system must correct for the eye movement by using an extraretinal, eye-velocity signal. Such correction is important in a variety of motion estimation tasks including judgments of object motion relative to the head and judgments of self-motion direction from optic flow. The Filehne illus...
متن کاملIllusory Tactile Motion Perception: An Analog of the Visual Filehne Illusion
We continually move our body and our eyes when exploring the world, causing our sensory surfaces, the skin and the retina, to move relative to external objects. In order to estimate object motion consistently, an ideal observer would transform estimates of motion acquired from the sensory surface into fixed, world-centered estimates, by taking the motion of the sensor into account. This ability...
متن کاملModification of the filehne illusion by conditioning visual stimuli
During smooth pursuit eye movements made across a stationary background an illusory motion of the background is perceived (Filehne illusion). The present study was undertaken in order to test if the Filehne illusion can be influenced by information unrelated to the retinal image slip prevailing and to the eye movement being executed. The Filehne illusion was measured in eight subjects by determ...
متن کاملDemonstration of an eye-movement-induced visual motion illusion (Filehne illusion) in Rhesus monkeys.
During pursuit eye movements, the world around us remains perceptually stable despite the retinal-image slip induced by the eye movement. It is commonly held that this perceptual invariance is achieved by subtracting an internal reference signal, reflecting the eye movement, from the retinal motion signal. However, if the reference signal is too small or too large, a false eye-movement-induced ...
