A questionnaire consists three scenarios was studied. All three scenarios were mainly studying people's reactions to buying and selling transactions that turn out to be less favorable than intended. Scenario 1 explored how people in the position of buyer or seller experienced different level of negative affect towards an unfavorable deal offer between the condition of close-call and non close-call. Results supported our assumption that people tended to feel better in the close-call condition than non close-call. Scenario 2 explored how people in the position of buyer or seller experienced different level of negative affect towards an unfavorable deal between the condition of outcome delay and outcome non-delay. Findings proved what we assumed that people tended to feel better in the condition of outcome delay than outcome non-delay. Scenario 2 also explored if upward counterfactual should elicit more negative affect and the results proved the assumption. Scenario 1 and Scenario 2 demonstrated if more negative affect generated from previous bad outcome should evoke more desire to achieve better outcome in the future. Results did not show consistency on the relationship between negative affect and future expectancy. Scenario 3 explored if people should feel better when accepting a bad deal at the second time than the first time in terms of diminishing sensitivity. Results from those participants in the single negative outcome supported our hypothesis, whereas results of those in the parallel negative outcome did not.
