In Experiment 1, participants successfully solved three cognitive tasks and attributed the success either internally (i.e., to themselves) or externally (i.e., to a teammate). We found no effect of optimism, but a significant effect of the attribution: Internal attribution predicted an increase in feelings of success. In Experiment 2, we replicated the design and adopted an extreme groups approach in order to include the extremes of the optimism dimension. Only optimism affected feelings of success in this sample: Pessimistic participants showed higher increases in feelings of success than optimistic participants. We conclude that optimism, if disentangled from attribution, may have an effect on affect, with pessimism showing potential affective benefits. However, this association may be concealed if samples with a restricted range of the optimism dimension are studied.
