Defensive pessimism and optimism: The bitter-sweet influence of mood on performance and prefactual and counterfactual thinking

Three studies demonstrated that manipulated moods influence the prefactual (alternative preoutcome predictions) and counterfactual (alternative postoutcome "what might have beens") mental simulations of defensive pessimists and optimists. In Study 1, negative moods induced more upward (better than expected) prefactuals, and defensive pessimists performed best under such conditions; optimists performed best under induced positive moods, after which they used little prefactual thinking. In Studies 2 and 3, manipulated moods again influenced the strategies of defensive pessimists and optimists. In Study 2, optimists responded with more downward (worse than actuality) counterfactuals, suggesting attempts at mood repair. In Study 3, defensive pessimists and optimists each coped effectively by using preferred mental simulation strategies; both groups rebounded on a second task from poor performances on a first task.
