Dispositional pessimism, defensive pessimism and optimism: The effect of induced mood on prefactual and counterfactual thinking and performance

This study analyses the extent to which dispositional pessimists differ from defensive pessimists and optimists in the generation of prefactual and counterfactual thoughts and in their performance in an anagram task, under different conditions of induced mood. Dispositional pessimists performed in a similar manner in all circumstances, recording an equal number of prefactual thoughts. By contrast, optimists and defensive pessimists optimised their performance under positive and negative conditions, respectively. It should be noted that after performing this task, the number of counterfactual thoughts expressed by dispositional pessimists varied according to mood states. The results are discussed in terms of the rigidity of the generalised expectations of dispositional pessimism.
