| As of June 13, 2014, there is a javascript bug preventing easy creation of new experiments. When attempting to submit the new experiment form an error dialog pops up saying the Sponsor field is empty, despite it being filled in. If this happens, you can fix it by inspecting the Sponsor input field element in your browser and deleting it from the DOM. You'll note that there is an additional hidden input field there that still has the sponsor information, so the form should work correctly. The admins have been informed, but have decided not to fix it. | ||||||||

| > > | Recording the dataIt's important to think about how you'll record the data before running the experiment. To run statistics on the results, you'll want to use a wide format for at least some of the data. By this I mean that each participant's data should be saved in a single row. It is a great idea to try and run some of your analysis on sample data from your experiment before running the experiment on real participants. This will hopefully ensure that you are recording all the data you need to analyze and storing it in a way that makes the analysis easy. As an example, you might record data with the following format, where the top row of data is in the wide-format (for statistical analysis), summarized from the raw data below:
userCorrect,disCorrect,dSlowDisCorrect,dMedDisCorrect,dFastDisCorrect,disOuterCorrect,disInnerCorrect,aCorrect,... 416,141,70,39,32,66,75,86,... Block,Trial,UserCorrect,DistractorCorrect,UserSpeed,DistractorSpeed,DistractorRow,DistractorCol,... slow,1,1,0,0,0,4,0,... slow,2,1,0,0,1,2,0,... slow,3,1,1,0,0,0,2,... slow,4,1,0,0,2,2,1,... slow,5,1,0,0,0,4,4,... slow,6,1,0,0,2,3,3,... slow,7,1,1,0,1,1,1,... slow,8,1,0,0,2,2,3,... ... | |||||||
Participant receipt formYou'll need a form for people to sign off indicating that they have been paid by you for having done the experiment. A sample template to follow has been attached to this page: receipt_generic.docx. At the completion of the experiment, this can be passed on to the program assistant for reimbursement. | ||||||||
