“…Our primary goal in this review was to assess whether discrete emotions elicit changes in cognition, judgment, experience, behavior, and physiology. The expectation that discrete emotions would have unique effects on multiple outcomes arises from a functionalist perspective that describes emotion as an evolutionarily adaptive response that organizes cognitive, experiential, behavioral, and physiological reactions to changes in the environment (e.g., Ekman, 1992; Frijda, 1987; Izard, Levinson, Ackerman, Kogos, & Blumberg, 1998; Lerner & Keltner, 2001; Mauss, Levenson, McCarter, Wilhelm, & Gross, 2005; Pinker, 1997; Plutchik, 2000; Rottenberg, Ray, & Gross, 2007; Tomkins & McCarter, 1964). Most versions of this perspective include the proposition that each discrete emotion elicits changes in cognition (e.g., narrowing of attention on a tiger in the distance), judgment (e.g., the risk perceived in the environment), experience (e.g., the recognition that one is afraid), behavior (e.g., a tendency to run away), and physiology (e.g., increased heart rate and respiration) that are adapted to facilitate a response to the types of environmental changes that elicit that emotion.…”
