URL of experiment: Pavlovia
Description of the problem: Need to access the changes we made on the shelf values- maybe like there is a log that is kept in server, because probably we have overwritten a lot of participants’ data in the shelf by mistake.
We were using shelf for multisession tracking and counterbalancing. We used a dictionary shelf to keep track of +180 participants progress in the experiment. At a certain point, we seemed to overwritten existing shelf values with progress data of a group of participants with default shelf values that show as if they did not start the experiment. This has cost us 31 participants’ data. Is there any way that we can access to logs of changes in these shelves to make sure that we actually did overwrite the shelves?
