Violin plots for tonic skin conductance in immediate (n = 49) and delayed extinction (n = 43) revealed a significant time effect. Tonic skin conductance decreased from the onset of acquisition (acq-onset) to the onset of the test (test-onset). Pre-extinction tonic skin conductance did not differ between groups.
