They conducted three experiments in gambling decisions and job selection decisions, where unhappy subjects were found to prefer high-risk/high-reward options unlike anxious subjects who preferred low-risk/low-reward options. They stated that "anxiety and sadness convey distinct types of information to the decision-maker and prime different goals." It was found that "while anxiety primes an implicit goal of uncertainty reduction, sadness primes an implicit goal of reward replacement".[21] Thus emotions cannot simply be classified as positive or negative as we need to consider the consequences of the emotions in ultimate decision-making.
