In this book, the authors discuss the psychology of empathy, which is described as a capacity acquired over the course of psychogenesis to imagine what others are feeling or thinking while distinguishing it from one's own feelings and thoughts. Topics discussed in this compilation include the amelioration of aggression through the development of empathy and compassion; extending empathy research towards animals; the psychophysiological measurement of empathy; empathy as a core component when working with children in play therapy; measuring empathy in teacher training for preventing violent behavior and school failure and clinical empathy in a medical context.
