Abstract: Alcohol consumption might lead to more extreme and destructive individual social behaviors, such as increasing risky sex, aggression, risk driving, self-disclosure, and so on. The mechanism of effects of alcohol consumption on social behavior has drawn more and more attention. Alcohol Myopia Theory and Alcohol Expectancy Theory are two influential explanations of alcohol-behavior link, thereinto, Alcohol Myopia Theory posits that alcohol impairs the information processing capability of individuals and Alcohol Expectancy Theory posits that alcohol outcome expectancy change social behaviors. Dual-processing model incorporates these two models into a dual-process framework, including both propositional process and associative process. The related research in the future could be studied based on dual-processing model. It is also important to explore effect of higher doses of alcohol and combine the neuroimaging technique to provide more comprehensive explanation of alcohol-behaviour link.

Key words: alcohol, social behavior, alcohol myopia, expectancy effect, dual-process model
