A functional theory of bistable perception based on dynamical circular inference
Fig 5
The circular inference model qualitatively reproduces the 4 Levelt’s propositions (here: wS = 0.9; aP = 1; ron = roff = 0.5). (A.) 1st proposition—increasing the stimulus strength of one perceptual interpretation increases the predominance of this perceptual interpretation. (B.) 2nd proposition—Manipulating the stimulus strength of one perceptual interpretation of a bistable stimulus does not equally influence the average dominance duration of both interpretations, but mainly affects the persistence of the stronger interpretation. (C.) 3rd proposition—Increasing the difference in the stimulus strength between the 2 perceptual interpretations should result in a decrease in the perceptual alternation rate (i.e., maximum number of switches at equi-dominance). (D.) 4th proposition—When we increase the strength of both interpretations, the number of switches increases.
