Distraction cost and time of AC measurement (pre-induction, post-induction) as predictors of average electrodermal activity (EDA) during the Trier Social Stress Test (TSST) tasks. Low, medium, and high distraction cost on the x-axis represent values that are one standard deviation below the mean, the mean, and one standard deviation above the mean, respectively. The estimates plotted on the y-axis are adjusted using the average EDA during the distraction task and accuracy rate during the distraction task as covariates in order to control for individual differences in autonomic arousal that are unrelated to state anxiety elicited by anxiety induction and autonomic arousal associated with the amount of error feedback encountered, respectively. Overall, higher distraction costs predicted a subsequently higher EDA response to the induction. Critically, this main effect was qualified by an interaction of Distraction Cost × Time of AC Measurement such that higher distraction costs only predicted higher EDA during the induction for the group with the pre-induction time of AC measurement (solid line) but not for the group with the post-induction time of AC measurement (dotted line).
