Participants will be randomly assigned to take the study with either our filler tasks embedded as the 20 minute filler, or 20 minutes of interactive sudoku puzzles. On the first page, to try to reduce dropout, participants first read (following Zhao & Fishbach, 2016) This study will take you approximately 25 minutes to complete. It is programmed in such a way that you cannot complete the study before then, because the materials are time-sensitive. Some people quit a survey halfway through. **If a sizable number of people quit a survey halfway, the data quality of that survey would be compromised. However, our research depends on good quality data.** Thus, please make sure you do not ming taking the full 25 minutes. Participants first fill out the information sheet. Then they will be given the quality check instructions. During this experiment, we ask that you comply with the following experiment requirements: [Response: Yes, I have done this.] Please maximize the size of your web browser so that it covers your entire screen. [Response: Yes, I have done this.] Please complete the experiment in a single session, and do not leave the experiment to engage in other tasks. So don't check your mail, look at Facebook, send or read a text message, get up for a drink, etc. [Response: I understand this instruction.] Please do not use your web browser's back or refresh buttons at any point during the experiment. [Response: I understand this instruction.] Because this experiment requires your close attention, we ask that you complete the experiment in an environment that is free of noise and distraction. Please do not speak to anyone, or have anyone near you. Ideally, you would be alone in a quiet room, or in a room where other people are quiet (such as a library). [Response: I understand this instruction.] Sometimes this survey will involve you working on one task for a specific period of time. Please remain on the task page for the full period of time we have asked of you. [Response: I understand this instruction.] This experiment uses sound. Please ensure that your computer's audio is functioning. [Response: Yes, I have done this.] Thank you for your help with these matters. Continue to the next page when you're ready to begin. Then participants read: This experiment consists of several tasks. Your first task is to pay attention to a short video. The video will appear on the next page of the survey. Please watch the video. The video has sound, so please ensure that your audio device is now on and at an audible volume. When the video ends, you will be able to continue the survey. When you are ready to view the video, please continue. On the next page, participants watched a 45-second video of a bank robbery, where the page could not move on until 45 seconds are up. Here, participants are randomly assigned to the different conditions. Thos in the Delay timing manipulation are randomly assigned to complete either 5, 10, 15, or 20 minutes of Sudoku puzzles. When taking the sudoku puzzles, participants read: That’s the end of that task. Now, please work on these Sudoku puzzles. You have [timing] for this task. The Sudoku puzzle below starts at the difficulty level set to easy. Feel free to change the difficulty level according to your liking by clicking on the "options" button below the puzzle. If you want to check whether you have solved your puzzle accurately, you can press the "check" button below the puzzle. If you complete a puzzle before the [timing] have passed, you can click on the "options" button below the puzzle, choose a new difficulty level, and will then be given a new puzzle to solve. Once [timing] have passed, you will be automatically forwarded to the next part of the experiment.* If you want instructions on how to solve a Sudoku puzzle, you can find them by scrolling to the bottom of this screen. Instructions on how to play Sudoku. Sudoku is played on a grid of 9 x 9 spaces. There are 9 rows in a Sudoku puzzle. Every row must contain the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9. There may not be any duplicate numbers in any row. In other words, there can not be any rows that are identical. There are 9 columns in a Sudoku puzzle. Like the Sudoku rule for rows, every column must also contain the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9. Again, there may not be any duplicate numbers in any column. Each column will be unique as a result. Within the rows and columns are 9 “regions” (made up of 3 x 3 spaces). Like the Sudoku requirements for rows and columns, every region must also contain the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9. Duplicate numbers are not permitted in any region. Each region will differ from the other regions. To summarize, each row, column, and region (9 spaces each) needs to be filled out with the numbers 1-9, without repeating any numbers within the row, column, or square. Complete the Sudoku puzzle so that each and every row, column, and region contains the numbers one through nine only once. A good start for completing your Sudoku is to first look for the same number in different rows, columns, or regions. Then, by process of elimination, you can remove that number for consideration those rows, columns, and regions and concentrate on what other numbers would be available. *Please note: If the Sudoku puzzles fail to load, you can still complete the experiment by returning to this page once [timing] have passed. We would ask that you please document what you did during those [timing] -- we'll ask you about that later, and it's information that is very useful to us. where [timing] if 5 minutes for the 5-min group, 10 minutes for the 10-min group, 15-minutes for the 15-min group, 20 minutes for the 20-min group, 25 minutes for the sham group, and 24 minutes for the 1-min E/C group. Participants are randomly assigned to the experimental or control groups after the timing is up. Then, all participants not in the sham condition read: Please read and follow the instructions on the next page. You will have five minutes to complete this task. You will need to work on this task for the full five minutes. Once five minutes has elapsed, you will be able to move on to the next task. On the next page Experimental Task: [5-minutes auto-advance for those in the 5-10-15-20 minute conditions, 1-minute auto advance for those in the 1-min E/C 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 Task: [5-minutes auto-advance for those in the 5-10-15-20 minute conditions, 1-minute auto advance for those in the 1-min E/C condition] Please name 50 countries and their capital cities. For example: France, Paris. Please do not look this information up online - we are interested only in your own answers. Thank you. Then, all participants read: That’s the end of that task. Next you will see a 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’. On the next page, participants in the 5-10-and 15-minute conditions will receive the sudoku puzzles again for 155 minutes, 10 minutes and 5 minutes (respectively). On the next page, participants see the lineup of 8 men and are asked: Please tick one of the following boxes to indicate your selection: On the next page: How confident are you in your selection from the lineup? [0-100 sliding scale with 5 centered labels (Very low, Low, Medium, High, Very high] On the next page, participants will be asked the original quality control questions. You will recall that we asked you to meet certain criteria and to take certain steps to avoid distractions during the experiment. Now we want to know if you really followed the rules we asked you to follow. We are going to pay you anyway, no matter what you tell us now, so please be honest. We need your honest answer so we know how to analyze the data you have provided us. Did you maximize the size of your web browser so that it covers your entire screen? [Yes = 0, No = 1] Did you complete the experiment in a single session, without stopping? [Yes = 0, No = 1] Did you pause or leave the experiment to engage in other tasks, even if they were other computer tasks? [Yes = 1, No = 0] Did you use your web browser's back or refresh buttons at any point during the experiment? [Yes = 1, No = 0] Did you complete the experiment in an environment that is free of noise and distraction? [Yes = 0, No = 1] Please select 'no' as the answer to this question, and remember the word 'horse'. On the next page, you will be asked to enter that word. [Yes = 1, No = 0] Did you complete the experiment without anyone helping you? [Yes = 0, No = 1] Did you speak with anyone at any time during the experiment? [Yes = 0, No = 1] Did you spend the full amount of time asked of you on each of the tasks? [Yes = 0, No = 1] If the Sudoku puzzles earlier failed to load, please let us know here what you did during that time. Have you seen the video of the bank robber prior to this study? [Yes = 1, No = 0] Have you participated in a study just like this one before? [Yes = 1, No = 0] If Yes Is Selected Could you tell us what that study was about? On the next page: What was the word? If you do not know, please just leave this answer blank. On the next page, participants read: Earlier in this survey, we asked you the following question: “Do you feel anxious when: Locating your car in a very large parking lot or parking garage.” What is your best guess of how you answered that question earlier? On the next page, participants are given a captcha and asked the seriousness check: It would be very helpful if you could tell us at this point whether you have taken part seriously, so that we can use your answers for our scientific analysis, or whether you were just clicking through to take a look at the survey? You will still be compensated no matter your answer. [I have just clicked through, please throw my data away = 0, I have participated in this survey seriously = 1] **References** Zhou, H., & Fishbach, A. (2016).
