a, Across age groups, fear-conditioned Event-Related Potentials (ERP) and Event-Related Pupil Responses (ERPR) to the arousal manipulation learned during re/conditioning (teal lines) were reinstated in the dichotic listening task (orange lines in the left and right, respectively). For ERPR and ERP analyses within age groups, see Figure 3 and Figures 4 and 5, respectively. b, Left, Within electrode and time ranges that demonstrated a reliable arousal effect during reconditioning, ERP and ERPR reinstatement data were correlated. A significant negative association was observed between t = 2.108 and t = 2.212 s (solid purple line). The topography between 1 and 2.3 s relative to CS onset (see gray horizontal bars) is shown below the time course. Right, For visualization purposes only, an additional scatter plot is provided, depicting the same association between ERP and ERPR reinstatement data (here ERP data are averaged over those samples [time, electrodes] that formed the reliable cluster [for cluster extent, see left]). Corr, Correlation; CS⁺: Conditioned stimulus; CS⁻: Neutral control stimulus, perceptually matched to the CS⁺.
