Binomial random walk function and skin conductance changes for each subject. A, The sequence of outcomes derived from a constrained binomial random walk function. This same function determined feedback outcomes in all subjects who consequently experienced the same sequence of reward and punishment.B, Normalized skin conductance responses for each subject over the course of the experiment from which the subject-specific regressors-of-interest were derived. C, Example of modeling of SCR events with δ functions parametrically modulated by height of SCR peaks.
