We hope to be as comprehensive as possible in our data collection and therefore would like to ask you whether you have any unpublished data, manuscripts, in-press papers, conference papers, dissertations, or informal write-ups that could be of help to us. Our inclusion criteria are: -Manipulation of social inclusion-ostracism via Cyberball (or any other tossing game that induces ostracism) -Immediate measures after the cyberball game (e.g., need satisfaction, mood), delayed measures (e.g., coping behavior), or a combination of immediate and delayed measures. -We are interested in successful and failed attempts If it concerns unpublished data or an unfinished write-up, please include a short description of the study (assignment procedure, conditions, measures) and test statistics (confidence intervals and effect sizes next to F and p values) or the data set from which we can retrieve these values. Any help is greatly appreciated and can be emailed to meta.cyberball@gmail.com (for ease of oversight). For questions, please feel free to email to c.hartgerink@gmail.com. Kind regards, Ilja van Beest, Tilburg University Chris Hartgerink, Tilburg University Jelte Wicherts, Tilburg University Kip Williams, Purdue University
