From the thesis abstract: "This thesis explores the impact of human neurobiology on the securitization process within the homeland security field. It proposes a model for how activation of the neurobiological security-motivation system can lead to securitization in response to a security speech act. It explores the model by qualitatively analyzing three examples of securitization processes in the homeland security field for security motivation markers: the 9/11 terrorist attacks, Russian social media propaganda, and the 2016 U.S. presidential election. This thesis found evidence that security motivation may be having an impact on security-related decisions within the homeland security field through its bias toward compulsive precautionary behavior rather than cognitive reassessment. It recommends 1) further study of security motivation triggers and duration of activation; 2) changes in the communication of potential threats by security practitioners; and 3) exploration of how trauma-informed practices can protect cognitive capacity and reduce compulsive security-related behavior."
