Might increased risk taking in adolescence result in part from underdeveloped conflict-monitoring circuitry in the posterior mesofrontal cortex (PMC)? Adults and adolescents underwent functional magnetic resonance imaging during a monetary game of "chicken." As subjects watched ostensible winnings increase over time, they decided when to press a button to(More)
Extensive literature has linked behavior control problems in childhood to risk for alcoholism, but impulsivity in alcohol-dependent adults has not been well characterized. Using a variety of laboratory measures of impulsivity, we assessed whether detoxified alcohol-dependent patients [(ADP); n = 130] were more impulsive than control subjects [(CS); n = 41].(More)
Although research has consistently demonstrated that condom use self-efficacy significantly predicts condom use, there has been little investigation of whether acute alcohol intoxication moderates this relationship. Because alcohol intoxication is often associated with increased sexual risk taking, further examination of such moderating effects is(More)
OBJECTIVE This study is a novel investigation of (a) the utility of the Theory of Planned Behavior (TPB) to predict men's condom use resistance (CUR; i.e., attempts to avoid condom use with a partner who wants to use one and (b) the effects of alcohol on endorsement of TPB-CUR constructs. METHOD Using an alcohol administration protocol, a between- and(More)
Recent scientific evidence demonstrates that many young men commonly resist condom use with their female sex partners and that both alcohol intoxication and a history of sexual aggression may increase the risk of condom use resistance (CUR). Using a community sample of heterosexual male non-problem drinkers with elevated sexual risk (N = 311), this alcohol(More)
In-the-moment ambivalence about having sex may influence sexual decisions but has rarely been examined. We investigated how ambivalence about sex might be related to intentions to abdicate sexual decisions to a male partner and to engage in unprotected sex in a community sample of young women. Predictors of abdication and unprotected sex intentions included(More)
To determine how naturally arising affect alters judgment, we examined whether (a) affective states exert a specific, rather than a general, influence on valenced-specific judgments; (b) neutral affect is associated with increased neutral judgments, independent of positive, negative, and ambivalent affects, and whether neutral judgments are associated with(More)
