Much research has found that positive affect facilitates increased reliance on heuristics in cognition. However, theories proposing distinct evolutionary fitness-enhancing functions for specific positive emotions also predict important differences among the consequences of different positive emotion states. Two experiments investigated how six positive emotions influenced the processing of persuasive messages. Using different methods to induce emotions and assess processing, we showed that the positive emotions of anticipatory enthusiasm, amusement, and attachment love tended to facilitate greater acceptance of weak persuasive messages (consistent with previous research), whereas the positive emotions of awe and nurturant love reduced persuasion by weak messages. In addition, a series of mediation analyses suggested that the effects distinguishing different positive emotions from a neutral control condition were best accounted for by different mediators rather than by one common mediator. These findings build upon approaches that link affective valence to certain types of processing, documenting emotion-specific effects on cognition that are consistent with functional evolutionary accounts of discrete positive emotions.Keywords: emotion, positive affect, evolutionary approaches, cognitive processing, persuasionImagine that you are watching a pleasant TV program. The program may be a travel show featuring awe-inspiring natural wonders or an animal program about a litter of puppies; it may be a sitcom that makes you laugh or an exciting sporting event. At some point during the program, you are likely to encounter a commercial message intended to persuade you. Given that any of these programs will elicit positive feelings, are you likely to process the persuasive message more carefully or more carelessly than if you felt no emotion at all?The answer to this question might initially appear simple: Much research already finds that positive affect leads people to process messages in a more heuristic or careless manner (e.g., Mackie & Worth, 1989;Schwarz & Bless, 1991; see Schwarz & Clore, 2007). In the present research, we demonstrate the complexity layered upon this general effect and address some of the mechanisms behind this complexity. Whereas traditional approaches have examined the influence of affective valence on cognition, our approach emphasizes differences among the likely evolutionary, fitness-enhancing functions of discrete emotions of the same valence and suggests that emotions of the same valence can have different consequences (Keltner, Ellsworth, & Edwards, 1994;Lerner & Keltner, 2000). Indeed, recent research has demonstrated that distinct negative emotions have emotion-specific influences on cognition (e.g., DeSteno, Petty, Rucker, Wegener, & Braverman, 2004;Lerner & Keltner, 2001;Mackie, Devos, & Smith, 2000). However, the question of how specific positive emotions might influence cognition has received far less attention (for notable exceptions, see Bartlett &DeSteno, 2006, andTiedens &Linton, 20...
