Abstract

Until recently emotion and emotional processing have been largely neglected by experimental psychology and neuroscience more generally. This paper reviews the substantial psychological and neuroscientific evidence that each emotion is localized in specific neural structures, and thus that it is not necessary to invoke souls or spirits to explain emotions or emotional processing often held to be distinctive of a soul. In addition, the paper aims to demonstrate the adaptive and biological value of emotion for humans and other animals. It closes by focusing on recent research on neural processing of emotions and emotional words. 1. Introduction -- 2. What are Emotions and How Many Emotions Exist? -- 3. Emotions and the Body -- 4.
