“…As a result, happy and angry participants (anger and happiness being associated with certainty appraisals) make similarly more optimistic predictions than do fearful participants (fear being associated with uncertainty). In a similar vein, participants respond faster to emotional stimuli with an approach movement when it is associated with happiness and anger than when it is associated with fear and sadness (the effect being reversed when participants respond with an avoidance movement; Alexopoulos & Ric, 2007). Other research on various areas of judgment, such as risk estimation (DeSteno, Petty, Wegener, & Rucker, 2000;Keltner, Ellsworth, & Edwards, 1993), stereotyping (Bodenhausen, Sheppard, & Kramer, 1994;Tiedens & Linton, 2001), prejudice (Cottrell & Neuberg, 2005), persuasion (Moons & Mackie, 2007), and consumer decision making (Han, Lerner, & Keltner, 2007), has revealed that the impact of negative emotions or stimuli can vary to a great extent depending on which specific emotion (e.g., anger vs. fear) the situation or the stimuli are eliciting.…”
