  1. Note: Post. Prob. = Posterior Probability score derived from script-driven imagery assessment; IES-R = Impact of Event Scale-Revised total score; Shipley Est. IQ = Estimated WAIS-R Full Scale IQ from Shipley Institute of Living Scale; EMG Diff_E1 = corrugator electromyogram differential response during extinction, i.e., the averaged CS interval response to the first five CS + trials minus the averaged CS interval response to the first five CS- trials for the extinction phase; BDI-II = Beck Depression Inventory-II score; SC Mean Resp. = Skin conductance mean response to loud-tone presentations.
