In both of these contexts\, decisions are often made on the move through an interplay of continuously changing sensory information and goal-oriented action selection. In this talk\, we present a dynamical systems framework for understanding how disc rete choices emerge through feedback between neural activity and movement through space. Starting from a stochastic ring-attractor model motivated b y biological neural circuits involved in perceptual evidence integration\, we will show how reduced representations such as competing neural accumul ators and local drift-diffusion descriptions of choice arise at different scales of the same process. Bifurcation analysis of the reduced decision d ynamics then reveals how movement reshapes competition among alternatives\ , and how asymmetries in target geometry and quality bias transitions from compromise to commitment captured through movement. These results link ca nonical models of perceptual choice and reveal how environmental geometry shapes embodied decisions. We will illustrate how insights from this biolo gically inspired modeling and analysis translate to novel design principle s for autonomous behavior in mobile robots.\n LOCATION:https://researchseminars.org/talk/Modeling_and_Computation/95/ END:VEVENT END:VCALENDAR
