How Jealousy Works

Le résumé fourni par la source

Abstract This chapter seeks to invigorate work at the boundary of knowledge about jealousy. First, the chapter conducts a task analysis of the adaptive problem that jealousy is hypothesized to solve. This task analysis reveals key gaps in current knowledge about jealousy. Second, the chapter presents an array of new, testable hypotheses about this important human emotion. These include hypotheses about within-sex individual differences (in contrast to the historical emphasis on between-sex differences), hypotheses about within-individual shifts in jealousy over time, and hypotheses about the distinct tactics the jealousy system should deploy in response to different forms of relationship threat. Finally, the chapter emphasizes the need for more research on jealousy in relationships other than monogamous mating relationships, including consensually non-monogamous relationships as well as non-mating relationships. This chapter contributes novel theoretical insights and suggests future directions that can help generate new empirical discoveries about this important human emotion.
