Participants will be tested in our Cognitive Psychology Lab. Participants will either be tested individually or two at a time. Two small testing rooms in our lab will be used for the study. The two rooms are next to each other, and the size of each room is 6 by 6 feet. Each room is equipped with an iMac computer with a 17-inch display and stereo headphones. The video will be displayed using QuickTime Player 7, and the lineup photo will be shown using Preview. Participants will not be able to hear or see other participants during testing.
