Dataset of Study 1 that replicates Diener et al. (2001) with a between-participants factorial design

These data are a direct replicate of the data in Diener et al. (2001) (Related Materials 2). A total of 237 students (mean age 18.90 years, standard deviation 1.02 years) attending a women's university in Tokyo participated in the experiment. Two scenarios were presented using an online survey system, and participants were asked to answer questions about each scenario. The two scenarios were positive and negative, and were presented in a fixed order from positive to negative. In each scenario, an experimental manipulation was performed for additional information. Due to the restrictions of the online system, the additional information condition was randomly assigned in each scenario. In the no extension condition, the subject saw the sudden death of the target person. In the extension condition, the subject saw that the target person lived a moderate life for five years. The participants then responded to two questions about the characters on a 9-point scale. The variables in the data were as follows: “id” (participant ID), “date_created” (start time of answer), “date_modified” (end time of answer), “age” (participant's age), “gender” (participant's gender: 0: male, 1: female), “department” (faculty affiliation), “condition1” (experimental condition for positive scenario; 0: no extension, 1: extension), “rate11” (desirability rating for positive scenario), “rate12” (happiness rating for positive scenario), “condition2” (experimental condition for negative scenario; 0: no extension, 1: extension), “rate21” (negation (desirability rating of the negative scenario)), “rate22” (happiness rating of the negative scenario), “rateh” (happiness score of the positive scenario), and “rateu” (happiness score of the negative scenario).
