A Synergetic Model of Multistability in Perception

Dynamic Neural Field Theory for Motion Perception

“…This result contradicts several models for the perceptual dynamics of the motion quartet that are based on the assumption that switches are caused by slow deterministic dynamical processes that model "attention", or physiological resource or fatigue effects [40,26].…”

“…This result disproves the sufficiency of the satiation hypothesis as explanation for the perceptual switching in the motion quartet. Additionally, it contradicts also several models for the perceptual organization of the motion quartet that are based on this hypothesis [39,40,26].…”

The dynamical foundations of motion pattern formation: Stability, selective adaptation, and perceptual continuity

“…In addition, Giese (1999) has shown that, in simplified form, the same principles can be the basis for quantitative simulations of the results of psychophysical experiments based on the motion quartet. Although all these phenomena could potentially have been comprehensively addressed by earlier dynamical models (e.g., Bartsch & van Hemmen, 1997;Carmesin & Arndt, 1996;Ditzinger & Haken, 1995;Francis & Grossberg, 1996;Grossberg & Mingolla,1985;Grossberg & Rudd, 1989Kawamoto & Anderson, 1985;Koechlin et al, 1999;Nowlan & Sejnowski, 1995;Williams et al, 1986), this is the first time that it has in fact been done. The results of the dynamical simulations in this article have been contrasted with Ullman's (1979) minimal mapping theory for explaining how the visual system solves the motion correspondence problem.…”

“…Our theoretical objective, therefore, is to unify traditional approaches, which have emphasized what is perceived when a motion stimulus is presented (i.e., the solution to the motion correspondence problem; see, e.g., Ullman, 1979), and dynamical approaches, which have emphasized the process of perceptualchange (e.g., Ditzinger & Haken, 1995;Kawamoto & Anderson, 1985;Koechlin, Anton, & Burnod, 1999;Schöner & Hock, 1995). Although most of the same concepts are inherent in other dynamical models (e.g., Chey, Grossberg, & Mingolla, 1997;Grossberg & Mingolla, 1985;Grossberg & Rudd, 1989;Koechlin et al, 1999;Williams, Phillips, & Sekuler, 1986;Wilson, Ferrera, & Yo, 1992), the proposed model stands apart for the following reasons.…”

A synergetic model for the verbal transformation effect

“…This frequency has without doubt a direct impact on the attention of the subjects. Following the lead of successful attempts to model moving ambiguous visual patterns (such as stroboscopic apparent movement) with a temporal coding scheme (Ditzinger and Haken 1995), further models of verbal transforms might consider adding a periodic force with amplitude A and frequency ω to the temporal evolution of the attention parameters:λ k = γ 1 − λ k − ξ 2 k + F k (t) + A cos(ωt), k = 1, . .…”
