Table 1.

Average across subjects (mean ± s.d.) of heart rate (HR), heart rate variability (HRV), high frequency power (HF), and skin conductance level (SCL) for selected regions of interest. Regions of interest include initial 5 min rest period (“Rest”) as well as periods at which subjects rated “1,” “2,” or “3.”
