Bridging emotion theory and neurobiology through dynamic systems modeling

Marc D. Lewis
2005 Behavioral and Brain Sciences  
Moreover, for an individual with a given emotion trait, only a small subset of these combinations occurs regularly (e.g., Horowitz 1998), and only one of these converges at a time.  ...  After identifying some limitations of mainstream emotion theory, I apply DS principles to emotion-cognition relations.  ...  These local states form chaotic itinerant trajectories (Tsuda 2001 ) that constitute a search for a course of action that can be predicted to restore balance.  ...
