Department of Psychiatry, Institute of Psychiatry, De Crespigny Park London SE5 8AF, U.K.
Received 12 March 1990; first review notified 5 July 1990; accepted 9 November 1990
Alcohol in two doses (0.75g/kg and 0.25/kg) and a placebo were administered to three matched groups of subjects. Subjective ratings and breath alcohol levels were completed pre-intake and at 30 min intervals up to 2 hr after intake. At 1 hr post-intake, the subjects took part in a competitive task with increasing rewards during which cardiac and electrodermal activity were monitored. Alcohol had very little effect. It did not affect the level of reward administered nor the physiological parameters measured. The only mood effect was sedation. There was no evidence of tension reduction or response disinhibition.
