UQAM Cognitive Science Institute, Montreal 2012 Self-Oscillator Model of Cognitive Bistability Explains Percept Reversal Rate Characteristics with Periodically Interrupted Ambiguous Stimulus Norbert Fürstenau German Aerospace Center, Inst. of Flight Guidance, Braunschweig Abstract A stochastic nonlinear dynamics model is presented which explains published experimental results with periodically ...
متن کاملSimulating Bistable Perception with Periodically Interrupted Ambiguous Stimulus using Stochastic Self Oscillator Dynamics with Percept Choice Bifurcation
Formal modeling of cognitive bistability (e.g.[1][2]) is an interesting problem because a constant stimulus (e.g. the Necker cube) excites quasi periodic alternations between only two well defined perception states. Periodic stimulus–off switching (toff < 1 s, ton = 300 ms) was introduced by Orbach et al. [3] as experimental paradigm to get more insight into the underlying perceptual dynamics. ...
متن کاملPercept-choice sequences driven by interrupted ambiguous stimuli: a low-level neural model.
Existing neural explanations of spontaneous percept switching under steady viewing of an ambiguous stimulus do not fit the fact that stimulus interruptions cause the same percept to reappear across many ON/OFF cycles. We present a simple neural model that explains the observed behavior and predicts several more complicated percept sequences, without invoking any "high-level" decision making or ...
متن کاملSwitching fuzzy modelling and control scheme using T-S fuzzy systems with nonlinear consequent parts
This paper extends the idea of switching T-S fuzzy systems with linear consequent parts to nonlinear ones. Each nonlinear subsystem is exactly represented by a T-S fuzzy system with Lure’ type consequent parts, which allows to model and control wider classes of switching systems and also reduce the computation burden of control synthesis. With the use of a switching fuzzy Lyapunov function, the...
متن کاملCompetition in bistable vision is attribute-specific
We employ ambiguous figures and rivalrous stimuli that have multiple ambiguous properties to show that the different attributes of an ambiguous stimulus can undergo independent switching dynamics. This suggests that competition is distributed and attribute-specific, consistent with the known functional segregation of visual processing. Conflicting evidence that binocular rivalry is an early or ...
