We will follow the approved protocol, however minor modifications were made to some protocol instructions to more clearly instruct participants how to proceed through the Medialab programming. Because we are using computers to run the experiment, instructions will be read on the computer screen by the participants and not verbalized by the experimenter. Participants will be tested in individual testing rooms so we believe that wearing headphones is no longer necessary. Subjects will be recruited to participate in a study of memory and perception. They will be asked to provide informed consent and be randomly assigned to either the experimental condition or control condition. On the computer, subjects will read: "This experiment consists of several tasks. First, please pay close attention to the following video. *Press Continue*." Subjects will then view a 30-second video depicting a bank robbery. Subjects will then receive different instructions depending on their condition assignment: In the experimental condition they will read: "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 robberʼs appearance. It is important that you try to describe him for the full 5 minutes” In the control condition they will read: "Please name as many countries and their capitals as you can." 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 countries and their capitals. It is important that you continue this task for the full five minutes.” Because participants may read through the first instructions at a slightly different pace, we have written instructions to tell participants about the crossword puzzle task. Specifically, after participants spend 5 minutes writing or typing, the computer screen will refresh and instructions will appear that read, “You will now be asked to complete a crossword puzzle. Please inform the research assistant that you are ready to start the crossword puzzle.” Each participant will then be given a crossword puzzle and will be verbally instructed to “please work on this crossword puzzle until you receive further instructions.” The timing of the crossword puzzle task (20m) will be kept within the computer program and will be monitored by the research assistant. The time will start as soon as the screen has been refreshed with the instructions, “You will now…” The time (countdown) will not be visually present to the participant but the RA will know when the time has expired because the page will refresh to the lineup instructions. At this point the RA will retrieve the crossword puzzle and tell the participants to “continue following the instructions presented on the screen”. At which point the participants will read the approved instructions, for the ID task and the confidence task. The instructions for the ID task and the confidence task will be “on screen” as participants make their decisions. The instructions have been modified to conform to medialab and will read, “Next you will see a lineup with 8 faces. Please *type in the number* of the individual in the lineup 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’. Please indicate ‘not present’ *by typing in* ‘9’. Next, Subjects will rate their confidence in their selection. They will be giving the following instructions: “Please indicate your confidence in your selection from the lineup on a scale from 1 (guessing) to 7 (certain).”After the confidence ratings, participants will be instructed to provide their age, gender, and race/ethnicity. Lastly, participants will read a debrief. The debrief will read, “Thank you for your participation in this experiment. The purpose of the experiment was to determine how giving a verbal description of a suspect, can influence your ability to subsequently accurately identifying the suspect. During your experiment you were either asked to give a description of the suspect (experimental condition) or asked to name world countries and capitals (control condition). The results gathered from this study will be used to inform legal practices, with the goal of reducing wrongful convictions based on mistaken eyewitness identifications. Please inform the research assistant that you are finished.” ***Participant Recruitment, Sample Size, Stopping Rules, Exclusion Principles, & Random Assignment:*** Each of these factors interact in our experimental design. All participants who are in the psychology experimental pool at Iowa State University will be allowed to participate and receive experimental credit. Therefore we will monitor the sample size of each condition and stop collecting data when we have at least 55 White participants (ages 18-25) in each condition. We will also use true random assignment (as generated by a random number generator) and therefore one condition will likely have more than 55 White participants before the second condition reaches 55 White participants (ages 18-25). Once the second condition reaches 55 White participants (ages 18-25) (while maintaining random assignment) we will stop collecting data. Once data collection has been stopped we will exclude participants if they meet one or more of the exclusion criteria identified in the approved protocol. These criteria include: They did not follow instructions on the experimental or control task. They did not complete all tasks. The Experimenter incorrectly administered the task or instructions. If more than five participants are excluded and the number of participants in either conditions drops below 50, we will continue with random assignment until each condition has at least 50 participants. All exclusions will be completed prior to data analysis and exclusion decisions will be unrelated to outcome performance. Nonetheless, all data (including participants who do not meet the inclusion/exclusion criteria) will be kept so that others can analyze across labs.
