Empathy or Empathies? Uncertainties in the Interdisciplinary Discussion

Summary The term empathy has become a linguistic commonplace in everyday communication as well as in interdisciplinary research. The results of the research questions, raised in the last hundred (and more) years, coming from different areas, such as aesthetics, psychology, neurosciences and literary theory, lack in fact a clear concept of empathy. Not surprisingly, a recent paper has identified up to 43 distinct definitions of empathy in academic publications. By reconstructing the main research lines on empathy, our paper highlights the reasons for this conceptual inadequacy and the deficiencies in the theorization of empathy that create misleading interpretations thereof. Along the line connecting Plato’s insights on empathic experiences to the present neuroscientific experiments, a broad spectrum of issues is deployed for which “empathy” functions as an umbrella term covering a net of categorical relationships – projection, transfer, association, expression, animation, anthropomorphization, vivification, fusion, and sympathy – that only partially overlap. Our paper therefore recommends that “empathy” should not be assumed as a self-evident notion but instead preliminarily clarified in its definition every time we decide to have recourse to it.

3D visual simulation of individual and crowd behavior in earthquake evacuation

Simulation of behaviors in emergencies is an interesting subject that helps to understand evacuation processes and to give out warnings for contingency plans. Individual and crowd behaviors in the earthquake are different from those under normal circumstances. Panic will spread in the crowd and cause chaos. Without considering emotion, most existing behavioral simulation methods analyze the movement of people from the point of view of mechanics. After summarizing existing studies, a new simulation method is discussed in this paper. First, 3D virtual scenes are constructed with the proposed platform. Second, an individual cognitive architecture, which integrates perception, motivation, behavior, emotion, and personality, is proposed. Typical behaviors are analyzed and individual evacuation animations are realized with data captured by motion capture devices. Quantitative descriptions are presented to describe emotional changes in individual evacuation. Facial expression animation is used to represent individuals’ emotions. Finally, a crowd behavior model is designed on the basis of a social force model. Experiments are carried out to validate the proposed method. Results showed that individuals’ behavior, emotional changes, and crowd aggregation can be well simulated. Users can learn evacuation processes from many angles. The method can be an intuitional approach to safety education and crowd management.
