During hand movement towards a goal involving electric shock, increased SCR amplitudes were observed for increased threat. In the presence as well as in the absence of alcohol, shock probabilities of 0.50 and 1.00 induced stronger SCRs than no‐shock control conditions. The outcome was related to behavioural measures of hesitation where an alcohol dose of 0.9 g/kg reduced hesitation significantly. It was concluded that the cognitive appraisal of threat remained unaffected by alcohol, whereas fear as reflected by hesitation was reduced. A highly significant decrease in SCR latency was observed under alcohol conditions ( p <0.001). Twelve volunteer S s served as their own controls in the alcohol/placebo X shock probabilities X replicates design.
