In the compressed file is a directory with the 10 datasets (.csv files) of confidence data from "Unique Effects of Sedatives, Dissociatives, Psychedelics, Stimulants, and Cannabinoids on Episodic Memory: A Review and Reanalysis of Acute Drug Effects on Recollection, Familiarity, and Metamemory." Unfortunately, some of the data are missing certain measures (e.g., stimulus/response onsets for computing reaction times), and some are already partially processed (e.g., data5_dxm_psi) because I didn't have access to the completely raw data. The data should be self-explanatory based on the manuscript (and the original manuscripts from which the data came), but e-mail Manoj Doss (mdoss3 at jhmi dot edu) if you have any questions.
