Neuromechanistic Model of Auditory Bistability

Scenarios for parametric dependence of perceptual dominance.
Schematic diagrams illustrate how the mean percept durations may change as a stimulus parameter S is varied and dominance shifts gradually from percept 1 to percept 2. The upper row illustrates the weaker percept being affected more and the lower row the stronger percept being affected more. A,D: Proportion of time when percept 1 is dominant decreases monotonically through equidominance (0.5) (dashed lines) in both scenarios. When S < Seq percept 1 is stronger, when S > Seq percept 2 is stronger. B,E: Percept durations are equal (T1 = T2 = Teq) at equidominance (S = Seq) in both scenarios. When the weaker percept is affected more the lower branches decrease more on either side of equidominance (B). When the stronger percept is affected more the upper branches increase more on either side of equidominance (E). C,F: The measure η (defined by Eq (3)) is zero at equidominance (S = Seq) for both scenarios. It decreases on either side of equidominance when the weaker percept is affected more (C) and increases on either side of equidominance when the stronger percept is affected more (F).
