The original study only used college undergraduates. As we are replicating this study in the general adult population, most participants will ave been out of high school for decades and not only a couple of years. Therefore, we will run two versions of the study, one that focuses on high school and one that focuses on changes in the past 4-8 years (to correspond to the time gap between college and high school). To preserve randomizaiton, participants will first be randomly assigned to either the high school or the 4-8 years ago conditions, then within condition be randomly assigned to the easy (3) or hard (12) condition. Participants will be randomly assigned to receive one of two versions of the questionnaire. In the short-list condition, participants were asked to list three things about themselves that had changed [since they had been in high school/in the past 4-8 years]. The instructions read as follows: On the lines below please list [3/12] things about yourself (your personality, your attitudes, your perspective on things, etc.) that have changed [since you were in high school/in the past 4-8 years]. List one thing about you that has changed on each of the lines, for a total of [3/12] separate things about you that have changed. Be as specific as you can in describing each of the things about you that have changed [since you’ve left high school/in the past 4-8 years]. The second page contained the dependent measures. The first question asked participants Please rate how hard it had been to think of 3 [12] ways you have changed [since high school/in the past 4-8 years] [7-point scale ranging from 0 (very easy) to 6 (very difficult)]. The next question asked participants Please rate how much you have changed [since high school/in the past 4-8 years] [7-point scale ranging from 0 (I haven’t changed at all) to 6 (I was very different in high school). The final four questions asked participants to rate how much various aspects of their external worlds had changed [since high school/in the past 4-8 years]. Specifically, they were asked Please rate how much your hometown, parents, teenage friends, and your high school itself has changed [since you have graduated high school/in the past 4-8 years. [7-point scale ranging from 0 (no change) to 6 (a great deal of change)]. The final 4 questions will be administered in random order
