Figure 2.

Significant fear-potentiated startle effects as a result of the threat manipulation were apparent during the predictable context [(A), difference scores cue minus context], and in the comparison between the Neutral and Unpredictable contexts [(B), difference scores (un)predictable minus neutral contexts]. Displayed are the mean magnitudes with standard errors of the mean. Data from the patient sample are plotted separately for the sessions in which the stimulator was on (plotted in blue) versus off (plotted in red), alongside the startle data from the control sample that was acquired as part of a different study (plotted in green).
