Physiological and Subjective Control Measures (all 128 subjects)

Physiological Subjective Control Measures for all 128 subjects in Uncertainty/Pharmacology Experiment Group 1 = PlaceboGroup 2 = DA- (Haloperidol)Group 3 = ACh- (Biperiden)Group 4 = NA- (Prazosin) Note that the data for the Visual Analogue Scales (VAS) for alertness, calmness and contentedness (Bond and Lader 1974) have been rearranged in alertnessflipped, calmnessflipped and contentednessflipped so that 0 is always minimum, and 100 always maximum, alertness/calmness/contentedness.

Where repeated measures were taken (i.e. for VAS, BP and HR):Column 1 = baselineColumn 2 = post-drug, immediately before starting the RT taskColumn 3 = post-drug, after completing the RT task Where differences from baseline were calculated (i.e. for VAS, BP and HR):Column 1 = post-drug (before task) - baselineColumn 2 = post-drug (after task) - baseline
