Performance on a Go-NoGo reaction time task in subjects classified by family history of alcoholism and score range on the California Psychological Inventory Sociability scale. Each group's performance is shown as Hits (responding correctly to a Go stimulus), Correct Rejects (withholding a response to a No-Go stimulus), Misses (failure to respond to a Go stimulus) and False Alarms (responding to a No-Go stimulus). A model containing Family History, Gender, and Cpi-So group accounted for a significant amount of variance in False Alarms. FH+, Positive family history for alcoholism, defined as having 1 or 2 alcoholic parents; FH−, No alcoholism in first-degree relatives for 2 generations; Low CPI-So, score of <30; High CPI-So, score ≥30.
