  The Hilbert space structure of classical field theory is proposed as a
general theoretical framework to model human cognitive processes which do not
often follow classical (Bayesian) probability principles. This leads to an
extension of the circumplex model of affect and a Poincar\'{e} sphere
representation. A specific toy field theoretic model of the brain as a coherent
structure in the presence of noise is also proposed that agrees qualitatively
with Pavlovian fear conditioning studies.
