M21 File Naming Conventions All file names should follow this format: Experi mentl D _ Subject! D _ T askl D _ Data Type Experiment ID is a 3-character code that tells us which experiment the data was collected for. Currently the lab is only running one experiment, Morph21, so the only Experiment ID (EID) is M21. There may be more in the future. Subject ID is the 4-character code that tells us which subject the data comes from. It should be S followed by the three-digit subject number. So 5201. In the future, we may also use P for practice/preliminary participants Task ID is a 3- or 4-character code that tells us which task the data shows. There are 2 tasks in our current M21 experiment; the Lexical Decision Task (LDT) and the Visual Statistical Learning task (VSL). Data Type is a 3-character code that tells us the type of data contained in the file. There are two options - BEH for behavioral data, i.e. data collected on the experimental computer (think reaction times, responses, etc.) and EEG for data collected from BrainVision on the control computer. When the experiment is over, you should have the following files to upload to Teams:
