Cognition, not to be confused with perception, reception, or stimulus detection, is defined as relationships of sensory experiences in single-loop matrices. The reticular system of the upper brain stem is centered upon as the likely locus of sensory filtering and modification that can modulate language usage. That is, higher cognitive functions are affected by the reticular matrices. Using an auditory input model, primarily, it is demonstrated that frequency, phoneme, and morpheme matrices are affected by the abductive logic of the reticular system studied. It is concluded that "language cognition is a probabilistic process of hierarchical matrices each responding holographically when matrices of the next lower level cumulate sufficient energy to activate them."
