<qa>  What is the primary outcome measure for retrieval-extinction?Outcome parameters: The co-primary outcome measures are: self-reported alcohol craving in the laboratory sessions before and after retrieval-extinction, and GMA reports of alcohol craving and drinking. Daily-life responses are important because the version of retrieval-extinction we will be using, with retrieval induced by drinking alcohol itself, rather than alcohol cues alone, may be especially likely to have effects that generalize from the laboratory to daily life. Secondary outcome measures are: 1 self-reported alcohol craving and drinking at 30-day follow-up, 2 physiological reactivity during sessions, and 3 urine biomarkers for alcohol consumption.
