Various work in AI attempts to create or emulate human emotion. Artificial emotion may be used for practical purposes, for example to make a chatbot seem more empathetic. In these cases it is often sufficient that the system appears to have emotion to the humans who interact with it. Artificial emotion may also be used in more theoretical work where the aim is to emulate the internal cognitive structures of emotion, that is to create a machine that in some sense has an internal emotional life. This may help understand human emotions, be used as part of more practical applications, or, for those pursuing strong AI part of a programme to create truly human-like AI. An example of this in the book is the modelling of computational regret, which was initially intended as a way to understand human emotion, but also found to have potental practical applications.
