This project is a Replication+Extension of Wagemans & IJzerman (2014; manuscript unpublished). The original study demonstrated that romantic partners may experience changes in peripheral temperature while viewing pictures of their partner's face displaying different expressions. This effect was moderated by participants' ratings of the reliability of their relationship (Communal Strength Scale; CSS; Mills et al., 2004) This is the workflow for running a **confirmatory study**. Be sure to follow the extra steps in the [Research Milestones Sheet][1] to pre-register your study prior to data collection. Follow these steps, using the existing components for organization: - Fork the research template into a new project. - Name your project. - Add your co-authors on this page (in the order that they will likely appear on the paper) - Fill in the name of the project, the order of authors, and the link to your new OSF project page in the Research Milestones Sheet (RMS). - Decide whether you will make the OSF page public at this time (the default initially is no, but in certain cases, it can be yes). - Review the literature and write the review. Develop your hypothesis and post them on the OSF. (Link to page in RMS). - Do your power calculation (NB: given the existing publication bias in the literature, we can likely not do a very reliable power calculation. The wisest approach is likely to take the smallest effect size of interest). (Link to completed power calculation in RMS). - Complete your proposed methods and include all materials needed to run your study. Post on OSF (link to page in RMS). - Write your syntax (SPSS, R, or other software program) and post on OSF (link to page in RMS). Preferably use simulated data to see if the code works. - Complete your ethics application if needed (in consultation with the lab's PI). - **Pre-register your study. By default, keep private unless otherwise decided (link to page in RMS).** - Before running study, double-check pre-registration. If you made a mistake before data collection, fork project and explain mistake (if so, link to fork in RMS. Pre-register project again). - After data collection, de-identify data so that participants cannot be recognized. If page/data will be made public, verify deidentification with PI. (link to page in RMS) - Post analytic code written after data collection (link to page in RMS). - Describe verbally on OSF which analyses were done separate from pre-registration (auxiliary/exploratory analyses; link to page in RMS). - Let data, code, and OSF page be checked by an independent researcher. Researcher should be able to use script to go from raw data to final results, and verify numbers in manuscript. Researcher should also verify deidentification. The independent researcher should be added to the OSF page and as second to last co-author on paper. Indicate completion on the RMS. - Post your completed RMS to the OSF page. - Post paper to a pre-print server after submitting paper to a journal (preferably PsyArxiv, so you can directly link to this project page).
