Grand averaged trial-by-trial EMG data for all trials for the healthy control (upper panel) and schizophrenia (lower panel) subjects. The 400 ms conditioned stimulus (CS) co-terminates with the 50 ms (10psi) air puff. Both groups developed conditioned responses (CRs) as the experiment progressed, as can be seen in the period just prior to unconditioned stimulus (US) onset (indicated by the boxed inset), but the schizophrenia group exhibited fewer and more poorly timed CRs compared to controls.
