Bistableperception arises when a stimulus is consistent with at least two interpretations.
We are interested here in the temporal dynamics of bistableperception, that is the temporal variations in dominance periods of one percept over another.
This result indicates that the mechanism responsible for the alternation of percepts is also sensitive to the stimulus properties that drive the first percept.
Multistable perceptual phenomena are a rare form of visual perception phenomena, characterized by an unpredictable sequence of spontaneous subjective changes.
The fascination of multistable perception probably comes from the active nature of endogenous perceptual changes or from the dissociation of dynamic perception from constant sensory stimulation.
However in mono-vision, such as that of photographs, the elimination of our depth perception causes multistable perception to take over, and this can cause the craters to inverse their depth values and instead look like plateaus rather than pits.

Bistableperception occurs during binocular rivalry when one eye views vertically moving dots while the other eye’s dots move horizontally.
Bistableperception also occurs with ambiguous motion, dots moving along elliptical trajectories as though on the surface of a transparent sphere.
The model I wished to test was that multistable switching rate could be predicted by combining the bistable switching rate of ambiguous motion viewed without rivalry (i.e., binocularly), and the bistable switching rate of binocular rivalry between similar unambiguous motion stimuli.
These forms of bistableperception exemplify the interpretive nature of vision, and may serve as useful tools to investigate how the visual system selects a particular interpretation to be represented in awareness.
It is generally thought that bistableperception results from lateral competition between visual representations at some level of the visual pathway.
If one assumes that different forms of bistableperception are mediated by similar mechanisms of pattern-based competition, it follows that attention should be about equally effective at biasing different forms of bistable competition.

Presenting the same stimulus intermittently rather than continuously tends to stabilize perception such that the rate of flipping is dramatically reduced.

5(c) where the perception is bistable, as the order between the two virtual squares is not de ned.
While the edge elements in both cases are identical, the perception is quite di erent.
2 It has also been shown that that the geometric interpretation of the meaning of images effects the perception of brightness [1] structure where each element is a child of the structure(s) that it is part of and a parent of the elements that were combined to form it.
It interests people who see it as an example of bistableperception or of multistable perception.
Porta and Dutour took it as evidence for an ancient theory of visual perception that has come to be known as suppression theory.
Wheatstone was able to prove that stereopsis depended on the different horizontal positions (the horizontal disparity) of points in the images viewed by each eye by creating the illusion of depth from flat depictions of such images displayed in his stereoscope.

Here we show that attentional modulation of dominance durations during binocular rivalry is limited compared to bistableperception of a Necker cube.
In no case could subjects increase the dominance duration of the desired percept, although they did show a limited ability to shorten the duration of the undesired percept.
The results suggest that unlike other bistable visual phenomena (e.g., Necker cube), binocular rivalry is resolved in early visual stages and cannot be accessed by high-level attentional processes.
