This Editorial reviews the challenges and advantages posed by a functional perspective on the relationships among emotion, behavior, and cognition. We identify the core themes among the articles published as part of this Special Issue. The articles generally address two important questions: (1) are emotions functional and what is their impact on behavioral and cognitive processes, and (2) how do the interactions among emotion, cognition, and behavior play out in particular situations that present adaptive challenges? We also identify two core questions raised by the articles included in this Special Issue. Future research must address the extent to which emotions are best represented as discrete emotional constructs (e.g., anger, sadness, fear) versus emotions that vary along dimensions, such as valence and arousal. Functional perspectives would also be facilitated by identification of situations or environments that are likely to elicit particular emotions and reactions.
People generally judge that the future will be consistent with their desires, in that they will experience desirable events and will not experience undesirable events. This desirability bias has been presumed to result from the desirability of the future events, but exactly how “desire” is represented psychologically has been largely undefined and untested. This investigation explored the contributions of positive/negative affective reactions and motivations to approach/avoid to the creation of desirability bias. In 4 studies, participants judged a future event to be more likely to occur if it had been paired with positive stimuli compared with negative stimuli. This desirability bias was eliminated when motivational tendencies were evoked that contradicted affective reactions (i.e., avoidance motivation for positive reactions, approach motivation for negative reactions; Study 1), and the impact of affective reactions on this desirability bias was partially mediated by behavioral indicators of motivations to approach or avoid events (Study 2). Desirability bias was also eliminated when participants acted to fulfill their approach/avoidance motivations before making their judgments (Study 3) and was present when motivation to approach/avoid was manipulated independently of affective reactions (Study 4). Together, these findings suggest a primary role for motivations in desirability bias, and that desire is best captured by motivations to approach or avoid stimuli.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
