Methods for the Science of Emotion
This chapter describes many ways to induce emotional states in the laboratory, including the use of film, music, scripted interaction, and the presentation of emotional images. The International affective picture system is a set of emotion-inducing images. F. Strack, N. Schwarz, and E. Geschneidinger and Schwarz and G. L. Clore systematically investigated the retrieval of emotional memories to induce emotional states in the laboratory. Music also causes people to feel emotions and can be used to elicit certain emotions in the laboratory. Scripted social interactions to induce emotions in the laboratory are particularly useful when the emotion under study is difficult to elicit with images, films, and music and when a very realistic state is desired. Central nervous system plays an important role in our emotional responding. Electroencephalography and neuroimaging methods are two measures that have been developed to assess emotion processes in the CNS.
