An illusory transformation of optic flow fields without local motion interactions
The focus of expansion (FOE) of a radially expanding optic flow pattern that is overlapped by unidirectional laminar flow is perceptually displaced in the direction of that laminar flow. There is continuing debate on whether this effect is due to local or global motion interactions. Here, we show psychophysically that under conditions without local motion transparency the illusion becomes weake...
متن کاملThe role of motion capture in an illusory transformation of optic flow fields.
In the optic flow illusion, the focus of an expanding optic flow field appears shifted when uniform flow is transparently superimposed. The shift is in the direction of the uniform flow, or "inducer." Current explanations relate the transformation of the expanding optic flow field to perceptual subtraction of the inducer signal. Alternatively, the shift might result from motion capture acting o...
متن کاملAn illusory transformation in a model of optic flow processing
We present results from computer simulations of a biologically plausible model of heading detection in the visual motion pathway of higher mammals. These simulations are closely related to a recently discovered visual illusion in optic flow processing in humans. The model reproduces the results described for humans and suggests a possible explanation, namely that humans interpret the illusory s...
متن کاملMechanism of the illusory transformation of optic flow fields
As part of our continuing studies of the neuronal correlates of optic flow, we noted their illusory transformation by overlapping patterns of planar motion (Duffy & Wurtz, 1993). We observed that planar motion, overlapping an outward radial pattern, caused the focus of expansion (FOE) in the radial pattern to appear to be shifted in the direction of the planar motion. In their current commentar...
متن کاملIllusory Motion
This study reports a new motion illusion in which saccadic eye movements can produce a perceived jump of a static stimulus presented dichoptically. In three experiments, observers made saccades while viewing a stationary stimulus consisting of a disk and random dots presented separately to the two eyes. In Experiments 1 and 2, by measuring the strength of the perceived motion and the velocity o...
