“…On the other hand, as the drinking well becomes deeper, it takes a longer time to return to the former motivation. This corresponds to similar phenomena reported in the animal behaviour literature [16]. where the upper bound is the theoretical limit at which the first well completely disappears.…”

“…Some of the early research in motivational conflict was related to the switching between two motivated behaviours (i.e. eating and drinking) [7,14,16,17]. The switching from eating to drinking can be thought of as the escape of the particle from the well corresponding to (p) to that corresponding to (q) in Figure 1, effectively jumping the barrier (r).…”

“…Dealing with motivational conflict is an important aspect of animal behaviour [19]. Consider, for example, the conflicting need to eat or drink as studied in [15,16], or the conflict between aggression and mating as exemplified by the response of male stickleback fish to territory invasion by a female conspecific [1]. The former conflict is driven by opposing intrinsic needs or deficits, the latter is driven by extrinsic factors, and in both cases conflict resolution requires multiple needs to be satisfied.…”

Motivation modulates behaviour depending upon contextual and internal cues. Like animals, successful artificial agents must implement different behavioural strategies in order to satisfy dynamical needs. Such causal factors emerge from internal homeostatic or allostatic processes, as well as from external stimuli or threats. However, when two or more needs coalesce, a situation of motivational conflict ensues. In this work we present a four-stage dynamical framework for the resolution of motivational conflict based upon principles from dynamical systems and statistical mechanics. As a central mechanism for the resolution of conflict we propose the use of potentials with multiple wells or minima. This model leads to behavioural switching either by means of a bifurcation or by the stochastic escape from one of the wells. We present analytical and simulation results that reproduce known motivational conflict phenomena observed in the study of animal behaviour, in the case of two conflicting motivations.
