Cognitive moderators of alcohol's effects on anxiety.

The present study was designed to test the prediction from the attention-allocation model that intoxication in the absence of a pleasant distractor will fail to produce anxiolytic effects. A second prediction, that the sequence of intoxication and exposure to the anxiety-producing situation would influence alcohol's effects, was also tested. Subjects were male social drinkers who received an 0.85 g/kg dose of alcohol or a placebo. Conventional statistical analysis of the results indicated an anxiolytic effect of alcohol on heart rate but a problem with this analysis is identified. An alternative interpretation provides no support for an anxiolytic effect. Exposure to the anxiety-producing stimulus prior to intoxication led to greater heart rate reactivity than if it followed intoxication.
