Figure Legend:
(a) Red/blue trajectories (destined for Percepts 1 and 2) show how the interaction of a finite β > 0 with any moderate A i
asymmetry (here, {A1, A2} = {0, 0.1}) shifts the Hi initial conditions sufficiently (blue) or insufficiently (red) to overcome the
Ai asymmetry-induced shift in the saddle point and separatrix (black trace). (b) Red/blue (Percepts 1 and 2) sectors in
(A1, A2) space show that with a fixed β (here, β = 4/(3α)) that is large enough to choose the more adapted attractor at low
and moderate Ai values (lower left sectors), there are still two upper right sectors at large Ai where the less adapted
percept is chosen. This inverted choice regime is essentially due to saturation at large A i of the shifts βAi/(1 + Ai) in the Hi
