The Fluency Amplification Model supports the GANE principle of arousal enhancement.

The GANE (glutamate amplifies noradrenergic effects) model described by Mather et al. offers a neurophysiological basis for the arousal mechanism which is essential for empirical aesthetics and Gestalt processing. More generally, the core principle of perception can be interpreted as a continuous processing of competing arousal states, yielding selective amplification and inhibition of percepts to deduce the meaning of a scene.
