An analysis of emotion

For example, one person may respond to being laid-off from a job with anger, while another person responds with joy—it depends on how the individual evaluates this event.

In particular, when the appropriate stimulus is presented to the system the triggering of the response is mandatory, meaning that once it begins it cannot be interfered with or stopped. Evolutionary Theories The evolutionary approach focuses on the historical setting in which emotions developed.
