Add Method details here ----------------------- - Participants will be tested individually in small soundproofed testing rooms in experimenter's lab space - Participants will be recruited from introductory psychology courses - Participants receive course credit for participation - Signup is handled by our Sona Systems website; study description reads "a study of perception and memory." - Participants will be excluded if they do not meet the stated age range. The overwhelming majority of participants do in fact meet this range - Sample is expected to be 65-75% female - Data from non-White participants will be excluded post hoc - Otherwise, data will only be excluded due to error (experimenter, computer, participant) or if subjects reveal themselves to be non-naive - Data will NOT be excluded based on outcome measures - Given time constraints, expected final sample size is 50 per condition - Anticipate testing 60 per condition to end up with a sample of 50 - We will stop once both conditions have a minimum of 50 Specific instructions from protocol: 1. Subjects are recruited to participate in a study of memory and perception 2. Subjects are randomly assigned to the experimental condition or the control condition. 3. Subjects are told: “This experiment consists of several tasks. First, please pay close attention to the following video” 4. Subjects view a 30-second video depicting a bank robbery. 5. Subjects receive different instructions depending on their condition assignment: Experimental Condition: “Please describe the appearance of the bank robber in as much detail as possible. It is important that you attempt to describe all of his different facial features. Please write down everything that you can think of regarding the bank robber’s appearance. It is important that you try to describe him for the full 5 minutes” Control Condition: “Please name all of the 50 US states and their capitals” 6. After 3 minutes, each group should receive the following reminder: Experimental Condition: “Please continue describing every detail of the bank robber. It is important that you provide as full a description as possible” Control Condition: “Please continue to list all of the states and their capitals. It is important that you continue this task for the full five minutes.” 7. After 5 minutes of writing/typing, all subjects should spend 20 minutes working on the provided crossword puzzle. Each participant should be given a printed copy of the puzzle. 8. Subjects view the lineup of 8 faces and identify the one they saw in the robbery video or report that it wasn’t present. They should read/hear the following instructions: “Next you will see an lineup with 8 faces. Please identify the individual in the line up who you believe was the bank robber in the video you watched earlier. If you do not believe the bank robber is present please indicate ‘not present’” 9. If the lineup task is computerized, the images are numbered 1-8 to allow a keyboard response and the last sentence of the instructions in #8 should add the following: “...please indicate ‘not present’ by pressing '9'. Press ‘space’ to view the image.” 10. Subjects rate their confidence in their selection. They should be giving the following instructions: “Please indicate your confidence in your selection from the lineup on a scale from 1 (guessing) to 7 (certain).”
