Notes. Upper numbers indicate correlations between the 0.1-Hz HRV change scores (baseline 0.1-Hz HRV subtracted) and original scores (i.e., without subtracting average ratings for neutral picture cues) of subjective ratings of arousals. Lower numbers in parentheses indicate correlations between the 0.1-Hz HRV change scores (baseline 0.1-Hz HRV subtracted) and change scores for the subjective ratings of arousal after subtracting ratings for neutral picture cues. All correlations were statistically non-significant at p < .05.
