A functional approach to violent radicalization. Building a systemic model based on a real casef Peco, Miguel Radicalization De-radicalization Terrorism Functional behavior assessment Cognitive-behavioral approach A paradox in the study of violent radicalization is that while each of the empirical findings can be explained with multiple theories, very few theories can explain a relevant number of these findings simultaneously. This paper conducts a functional behavior assessment of violent radical behavior, investigating the factors responsible for its initial learning and subsequent maintenance. Specifically, a model of radicalization is proposed that can explain a wide range of observed phenomena, accommodate apparent exceptions, and obtain testable consequences. It also challenges some firmly rooted ideas, as the alleged existence of aggressive influence practices, or brainwashing. Finally, the model can also provide valuable predictions for subsequent research, such as those related to the reversibility of the process of radicalization. 2016-05-31T10:11:03Z 2016-05-31T10:11:03Z 2016-06 journal article Miguel Peco, “A functional approach to violent radicalization.
