  1. Number and percentage of individual decisions to avoid or to receive the US and reaction times during the avoidance phase, subdivided regarding the respective prior pain-related experience, i.e. following a prior experience of an unsignaled unconditioned stimulus (US) at a random time point following the decision (left panel), following successful omission of US as a result of the avoidance decision (middle panel) or following the prior experience of a signaled US in the preceding trial due to the decision to not avoid (right panel). Results of Fisher’s Exact Tests comparing the respective proportions of avoidance and non-avoidance decisions within the respective prior experience conditions are reported, and data on reaction times in seconds are given as mean ± SEM. *** p < .001, * p < .05.
