Figure 4.

Figure 4

Individual autonomic response vectors for 43 participants. Data from the same randomly chosen subset of 22 participants are presented in the top and bottom panels on the left; the remaining participants are presented in the right panels. As illustrated in these panels, notable individual differences in autonomic response magnitude and autonomic mode of cardiac control are apparent both within and between tasks. Note that the sign of the values along the abscissa is reversed as in Figure 3, indicating that more negative values correspond to greater decreases in PEP.
