The feedback data set contains the independent variables outcome (gain (keep) = ...55.100.MN5, gain (gamble) = ...52.100.MN5, loss (keep) = ...56.100.MN5, loss (gamble) = ...51.100.MN5), decision (keep = ...55.100.MN5, ...56.100.MN5, gamble = ...51.100.MN5, ...52.100.MN5) and stimulation (sham = ...100.MN5, excitatory = ...200.MN5).

The behavioral data can be analyzed with the provided R-script. Choice behavior depends here on the risk-of-losing, the frame and the stimulation. Furthermore trial number has an important influence on decision-making as it indicates learning. The R-script will recode all the independent variables into a meaningful form. Regarding the Choice: 1 = gamble, 0 = keep.
