 Models of cognition in immune theorizing have been extended from human cognitive science and linguistics, where representational and anti-representationalist orientations have vied for dominance (Tauber 2013). The dominant model regards the immune response integrating two steps: First, the immune system perceives molecular targets and then “decides” how to react (Cohen 1992a). Accordingly, “perception” is primary and effector functions (activation or tolerance) follow along a spectrum of responses. This understanding of immune cognition construes immunity as an information-processing faculty, where immune activity becomes a computational process involving algorithmic transformation of an antigenic input into an effector output (Cohen 2007b).
