Finally, to make sure you remember which items you found, you'll be tested for your memory. This test will come after your tour of the two cities. You'll see a series of items, some of which are ones you found and some of which you didn’t. You will be asked to distinguish which ones are new (you haven't seen before), versus which ones are old (you had found).
Although you should pay attention to your findings, you do not need to actively memorize or write down the items. Although your memory will be tested, you will not be penalized for your memory performance.
Note: To receive full payment, you will need to complete this experiment and submit it. In the case of an event that precludes you from completing the experiment, please return the HIT and do not submit it. In that case, please e-mail nrouhani@princeton.edu to be compensated for the time you did spend on the task.
