Abstract:Death reflection refers to the deep reflection and examination of life and death caused by facing death directly. Different from emotional reactions such as death anxiety and fear, death reflection is closer to a cognitive state, which is thought at the level of consciousness. Both practical cases and laboratory studies have showed that death reflection can lead individuals to choose a firm and sincere life and gain growth. The Emotional Rationality Hypothesis, Dual Existence System and Model of Post Traumatic Growth respectively elaborate how death reflection can bring about growth from the perspectives of emotional response, cognitive processing and psychological adaptation, which lay a theoretical foundation for in-depth research on the psychological mechanism of death reflection, but also have their own limitations. Finally, this paper emphasizes that life and death cannot be separated. To clarify what kind of growth does death reflection bring and how death reflection brings about growth is to call for a life of "tasting death", so as to "live towards death".
