While most visual input produces normal stable vision, when visual information is ambiguous our brain does something uncharacteristic, it wavers. When visual information is ambiguous awareness tends to waver continuously between alternative interpretations.
Ambiguous vision has received tremendous interest from a broad array of researchers. This is, in part, because it allows investigators to dissociate low-level physical stimulation from fluctuations in perceptual awareness, providing a valuable tool for investigating the neural basis of visual awareness. Research ideas using instances of ambiguous vision to investigate aspects of perceptual awareness would be welcome.
