Abstract
Individual sociability and alcohol drinking are interacted to escalate alcohol use. An impairment in perceiving and discriminating the difference in incentive values between social interaction and drinking behavior indicates a shift from moderate alcohol consumption to misuse. However, few studies have evaluated the incentive value of these two behaviors in the same scenario. Thus, we modified a behavioral test protocol to evaluate rodents' ability to perceive and discriminate the differences in incentive value between alcohol drinking and interaction with their social partners. The present protocol is simple and practicable. Only 2-3 days are required to complete the whole process. Compared with existing methods, our protocol is simple and practicable. Our findings suggested that subtle changes in the incentive value of distinct behaviors can be accurately and reliably assessed using the present protocol in mice with low or high levels of alcohol preference.•We described a modified behavioral test protocol to simultaneously evaluate the incentive value of alcohol drinking and social interaction.•The subtle changes in the incentive value of mice with different levels of alcohol preference can be accurately and reliably assessed in the present protocol.•Using our modified protocol, the differences of incentive value between distinct behaviors can be accurately and reliably assessed in mice with different risks to develop into AUD.
