Simulation results of bistable perception due to ambiguous visual stimuli are presented which are obtained with a nonlinear dynamics model using delayed perception---attention---memory coupling. Percept reversals are induced by attention fatigue with an attention bias which balances the relative percept duration. Periodic stimulus simulations as a function of stimulus off-time yields the reversal rate variation in surprisingly good quantitative agreement with classical experimental results reported in the literature [1] when selecting a fatigue time constant of 1 --- 2 s. Coupling of the bias to the perception state introduces memory effects which are quantified through the Hurst parameter H, exhibiting significant long range correlations (H 0.5) in agreement with recent experimental results [2]. Percept transition times of 150 --- 200 ms and mean percept dwell times of 3 --- 5 s as reported in the literature, are correctly predicted if a feedback delay of 40 ms is assumed as mentioned in the literature (e.g. [21]).
