**EDITOR'S INSTRUCTIONS: For each section below, replace the italicized text with the relevant information about your own replication project. Do not change any of the other text or headings. You can add additional headings as needed (e.g., if you are translating the materials, add a "translation" heading and describe your procedures.) When you are done, delete these editor instructions.** Implementation Details ---------------------- This page describes how our lab implemented the procedures required by the official protocol for the RRR. It also describes and justifies any additions to or departures from that protocol. You can view the official protocl and the main project page for this RRR using these links: - Official Protocol: [https://osf.io/6wvj4/][1] - Main RRR project page: [https://osf.io/hgi2y/][2] - Project page with all materials: [https://osf.io/pkd65/][3] ---------- #### Experimenters #### *Please note the qualifications/training of those who are conducting the testing and describe how any research assistants were trained on the protocol. Note any expertise with the topic area or methods used in this study. You already provided most of this information on your application.* ---------- #### Setting/Lab/Equipment #### *Please describe the testing environment in as much detail as possible. Include details of any equipment/computers you will use, where participants will be tested (i.e., describe how the testing space is arranged so that participants won't feel observed by other participants or the experimenter). Please upload photographs and/or video of your lab arrangement to the Files section of this component. You can do that by clicking the Files link at the top of the page - the interface allows you to upload files. You can also embed the images here using the picture icon in the formatting palette that appears at the top of this window when you're in editing mode. Make sure to describe how participants will be isolated from each other and how you will ensure that participants do not feel observed when performing the task (a requirement of the protocol). Please also explain how the camera will be positioned to record how the participant is holding the pen (needed to verify that they are following instructions properly).* ---------- #### Sample, subjects, and randomization #### **Target sample size:** *Specify how many participants you plan to test in total.* **Target sample demographics:** *Describe the source of your participants, how they will be compensated, and predicted demographic characteristics.* **Minimum sample size after exclusions:** *Specify your minimum sample size. Once you register your page, you will need to continue collecting data until you reach this many usable participants. Note that your minimum sample size must exceed the protocol requirement of 50 participants in each condition.* **Stopping rule(s):** *Describe how you will ensure that your sample meets or exceeds your minimum sample size. How will you determine when you will stop collecting data. Anticipate what you would do if you, after meeting your planned stopping point, you needed additional participants after exclusions. That is, how does your stopping rule allow you to still meet the minimum sample size requirements for the protocol.* **Randomization to conditions:** *Describe in detail how participants will be randomly assigned to conditions. Please be precise in your description. You may assign participants pseudorandomly by assigning every other participant to each condition. Or, you may generate a randomly ordered list of condition assignments so that you have equal numbers of participants in each condition. When discussing your randomization procedure, please describe how you woudl handle random assignment should you need to test additional participants.* **Blinding to conditions:** *Describe how you will ensure that participants are unaware that other participants were asked to hold the pen in a different way.* **Exclusion rules:** *Describe how you will handle data exclusions. The official protocol describes a number of reasons for exclusion. If you will be using any other exclusion rules, specify them here. If not, just state that you will be using the same exclusion rules required by the official protocol. Note that if you exclude participants, you should retain their data, but mark them for exclusion. And, exclusion decisions should be made by someone blind to condition assignment.* ---------- #### Software/Code #### *Please confirm you will be using the provided materials, including any software or scripts, and that you have verified that they work in your laboratory.* ---------- #### Differences from the official protocol #### *Note any significant additions to or departures from the official protocol. Feel free to add dividers and subheadings here if necessary. If you are adding additional measures or conditions to the end of the study, you should give full details here. Please make sure to explain why adding these measures will not affect the primary tasks and measures. It's fine to upload a file and refer to it for additional details as needed. If you are using translated materials, note those here too and describe your translation procedures (who translated them and how you back-translated them to verify the accuracy of the translations). Upload the translated files on your page as well.* [1]: https://osf.io/6wvj4/ [2]: https://osf.io/hgi2y/ [3]: https://osf.io/pkd65/
