“…With small to moderate doses (0.1-0.8 g/ kg), however, the variation in the results makes generalization more difficult. For example, Palva et al (1979) reported that psychomotor performance was improved after 0.5 and 0.8 g/kg of alcohol ingestion, whereas Fagan et al (1987) determined that 0.2, 0.4, and 0.8 g/kg of alcohol had no effect on psychomotor performance. These variations in the effects of small to moderate doses could result from many factors: development of tolerance, variable sensitivity to ethanol, intra-and inter-individual differences in absorption, metabolism, and drinking habits, task familiarities/complexities, and experimental design.…”
