Two panels show mean and standard error of absolute value of changes in interbeat interval from Pretest during unconditioned stimulus testing as a function of whether training took place at the same location as during unconditioned stimulus testing (Same) or at a different location as during unconditioned stimulus testing (Different) during the first 1000 ms of the observation interval after unconditioned stimulus onset for testing near the eye or last 1000 ms of the observation interval for testing on the back of the observation interval on Post Test 1 the day after heart rate conditioning (top) and on Post Test 2 a week later (bottom).
