Thank you for your participation. The study you just completed investigated how desires for a particular outcome might influence expectations about such outcomes and how that might vary based on the type of prediction you are making.
In this study, you either won or lost points depending on the color from a random draw. If certain color outcome was associated with earning point, we assumed you would want that outcome to occur in the hopes that you complete the study faster. Our interest was in whether this desire for the outcome would make you more optimistic about that particular outcome than usual. In other words, would your predictions be biased? Alternatively, perhaps wanting a particular outcome would make you pessimistic about it, because you wanted to avoid being disappointed by a negative outcome. We hypothesize that there will be an impact of desire such that people will be more likely to predict “winning” color even under conditions where this doesn’t seem to be the most likely outcome. Your data will be combined with others to help us address our questions.
If you have any further questions about this study, please contact Prof. Paul Windschitl at 319-335-2435, or e-mail: paul-windschitl@uiowa.edu.
