"When we do not know the cause of our negative states – referred to as mood states by psychologists--we use the moods themselves as information about our environment," explain Rajagopal Raghunathan (University of Texas at Austin), Michel Pham (Columbia University) and Kim Corfman (New York University).
The authors demonstrated this effect by putting subjects into a sad, anxious, or neutral mood, then having them make choices that were unrelated to the source of their feelings. While both anxiety and sadness exerted a strong influence over decision-making, different types of negative emotions encouraged different choices.
"While anxiety triggers a preference for options that are safer and provide a sense of control, sadness triggers a preference for options that are more rewarding and comforting," write the authors.
Even when the subjects had identified the cause of their sadness or anxiety, however, decisions moderately and superficially related to that cause were still affected by the negative emotions. The authors term this "displaced coping," and their study is the first to distinguish this phenomenon from more tangential effects of negative emotion.
