¹Such a multi-component definition of emotions, for example by Scherer (2009), is wide-spread in psychological literature. In contrast, in neuroscience and AI emotions are often defined more narrowly, or not properly defined at all. The list of such components given in the text is not at all complete, in particular bodily responses (Nummenmaa et al., 2014) and social aspects (Nummenmaa et al., 2012) could be added.
