title: Arousal-biased preferences for sensory input: An agent-centered and multisource perspective.
abstract: I argue that the GANE (glutamate amplifies noradrenergic effects) model basically explains an arousal-based amplification of emotional stimuli, whereas effects on neutral stimuli indicate a contextualization process aiming to reduce stimulus ambiguity. To extend the model's validity, I suggest distinguishing between internal and external emotional sources, as well considering the stimulus valence and addressing age-related differences in attention and memory preferences.
