Single-trial data for the two behavioral experiments from the following paper are published here:
[Schneegans, S., & Bays, P. M. (2018). Drift in neural population activity causes working memory to deteriorate over time. Journal of Neuroscience, 38(21), 4859-4869.][1]
The data is available in the form of Matlab tables in the file data.mat, or as separate csv-files. Descriptions of the table entries are contained in the Matlab variables (use e.g. summary(dataExp1) to see these in Matlab), and in the separate file info.txt.
