Comparisons of HRD to loud tones across sessions and between times-of-day. A. First Session-Pair Analyses showing significantly greater HRD Mean Response at the second (PM) compared to the first (AM) session in the APAPA group (N=13 APAPA, 15 PAPA). B. Analyses by Session-Order for Change Across Session Pairs across 2 PM to AM sessions in the PAPA group compared to 2 AM to PM changes in the APAPA group. There were significantly greater decreases across both PM to AM sessions combined in the PAPA group than across both AM to PM changes combined in the APAPA group (N=10 APAPA, 11 PAPA). C. Analyses by Time-of-Day collapsing across groups showing significantly greater HRD to the loud tones in the PM compared to AM (N=21). HRD BPM1/2: square-root transformed heart rate deceleration in beats-per-minute, * p < .05, Error bars depict standard error of the mean.
