Existing research on the “weapons effect” indicates that simply seeing a weapon can prime aggressive thoughts and appraisals and increase aggressive behavior. But how and why does this happen? I begin by discussing prevailing explanations of the weapons effect and propose that these accounts tend to be over-intellectualistic insofar as they downplay or overlook the important role played by affectivity. In my view, insights from the fields of situated affectivity and enactivism help us to understand how cognitive and affective processes (...) jointly contribute to the weapons effect. Insofar as the presence of weapons alters subject’s bodily-affective orientation and thereby brings about embodied mindshaping, it changes the way they engage with and understand their surroundings. To understand the weapons effect, we will need to examine the constitutive interdependency of appraisal and affectivity and the way in which they jointly motivate action. My proposed account emphasizes the role of affectivity in affordance perception and the way in which subjects gauge the meaning of an object according to its action-possibilities. (shrink)
