Note. AAT = approach/avoidance task; GNG = go/no-go task; The GNG RT variable is a difference score (nonalcohol-cued “go” trial RTs – alcohol-cued go trial RTs), such that more negative values indicate faster RTs to alcohol cues relative to nonalcohol cues. P300 = amplitude of the P300 elicited by low probability, alcohol-cued no-go trials during the Cued Go/No-Go Task; N200 = amplitude of the N200 elicited by low-probability, alcohol-cued no-go trials during the Cued Go/No-Go Task. GNG Accuracy = proportion of low probability, alcohol-cued no-go trials during the Cued Go/No-Go Task (arcsine transformed) where no response was made; larger (more positive) values indicate better performance; Q/F = alcohol quantity-frequency, calculated as the number of drinking occasions per week multiplied by the typical number of drinks consumed on one occasion.. Sensitivity is scored such that greater (more positive) values represent lower sensitivity (i.e., needing more drinks to feel a given effect).
