abstract="The aim of this study was to observe if a method useful for measuring attentional effects could be applied in testing the differential effects of caffeine, the beta-stimulant salbutamol, and the beta-blocker propranolol. Caffeine (300 mg) was administered to a sample of 19 normal subjects compared to two samples of 40 controls. Caffeine was found to increase attention and vigilance by augmenting the number of repetitions of responses to a verbal stimulus in a free word association test. This pattern was also seen with salbutamol and propranolol, but to a lesser degree.<p /><p>Language: en</p>",
