Before revision: Motivational salience is a mechanism that determines URLanism's current level of attraction to or repulsion from a particular object, event, or outcome. Motivational salience is described by modulating the reward by an externally controlled parameter that remains constant within a single behavioral episode. The vector of perceived values of various outcomes determines motivation of URLanism toward different goals. Organism's behavior should be able to adapt to the varying-in-time motivation vector.
