Moderation of habituation to negative stimuli by anxious apprehension. SFG, superior frontal gyrus; IFG, inferior frontal gyrus; dACC, dorsal anterior cingulate; Blue, high PSWQ associated with habituation; Red, high PSWQ associated with increased activation over time. The graphs depict the change in neural response to negative words over time at +1 (circle endpoints) and −1 (triangle endpoints) standard deviations (SD) and the mean (square endpoints) of the Penn State Worry Questionnaire (PSWQ). Time (1st task half and 2nd task half) is plotted on the x-axis against brain activation related to negative stimuli (negative minus neutral) on the y-axis. Graphs reflect values with normalized MASQ-AA and MASQ-AD-LI partialled out.
