Research in how emotions impact decision making is growing and the corresponding literature is often organized around types of emotions. These types can be thought of as labels that categorize how emotions enter into decision making. Examples include "expected", "integral", or "incidental" emotions. Taking a closer look at several of these categorizations however, one is confronted with discord and a considerable number of inconsistencies in naming conventions, definitions, scope of the categorizations, as well as a lack of clear approach to how emotions might enter into decision making. Given the ubiquity of these categorizations, in this paper, we conduct a review of types of emotions, we address some of the inconsistencies, and we present a new way of categorizing how emotions enter into decision making -one where emotions are categorized in relation to the decision and affective components of the decision making process.We discuss how this new categorization deals with the identified inconsistencies and ways in which it can be conducive to developing novel theoretical and empirical investigations in how emotions impact decision making.
How Emotions Enter into Decision Making: A Novel Categorization of Types of EmotionsEmotions have an undeniable impact on judgment and decision making (JDM). It has been shown that emotions can, dependent on the decision situation, lead both to suboptimal (e.g., Ariely & Loewenstein, 2006;De Martino, Kumaran, Seymour, & Dolan, 2006;Mikels, Cheung, Cone, & Gilovich, 2013;Ratner & Herbst, 2005) and superior (e.g., Bechara, 1997;Koenigs & Tranel, 2008;Mikels et al., 2010;Shiv, Loewenstein, Bechara, Damasio, & Damasio, 2005) decisions. Furthermore, interest in emotions and the impact that they have on JDM has been on the rise. Lerner, Li, Valdesolo, and Kassam (2015, supplemental material), for instance, found that the yearly output of published papers on this topic increased by an order of magnitude from 2001 to 2013.Most researchers in this domain seem to agree that there are several ways in which emotions can enter into decision-making. As a result, distinctions have been made between different types of emotions (e.g., integral, incidental, expected, immediate, etc.) which categorize the ways emotions can enter into JDM. Nearly every major review of the emotion and JDM literature highlights types of emotions and theoretical frameworks are often-times distinguished dependent on the type of emotion they focus on. For example, the "appraisal tendency framework" (Lerner & Keltner, 2001) focuses on incidental emotions while "decision affect theory" (Mellers, Schwartz, Ho, & Ritov, 1997) focuses on anticipated emotions. Types of emotions are also referenced in empirical research. For example, attempts to reach a better understanding of the mechanisms of the emotional impact on decision making have incorporated different types of emotions into complex mediation models (Charpentier, De Neve, Li, Roiser, & Sharot, 2016;DeWall, Baumeister, Chester, & Bushman, 2016) and coherent ...
