Figure 2

Time series (Column A) and phase portraits (Column B) of pain prediction accuracy simulated using a 4th order Runge-Kutta algorithm for participants that were either in the top (solid lines) or bottom (dashed lines) thirds on negative affect (NA; Top Panel), positive affect (PA; Middle Panel) and pain control (Bottom Panel). The effect of individual difference variables on nonlinear damping are displayed through the differences between groups in oscillation amplitude in the time series and the shape of the spiral in the phase portrait.
