Recent conceptualizations of alcohol expectancies relate cognitive schemas to their neurobiological underpinnings; cue reactivity paradigms lend themselves well to testing this broadened conceptual framework. In the present study, we examined the relationship between self-reported alcohol expectancies and responses to alcohol-related and affective picture cues among fifty-five young adults. In addition to traditional subjective and psychophysiological indices of cue reactivity, the startle eyeblink reflex was obtained during picture cue presentations to address both attention-arousal (early probes) and affective-motivational (late probes) aspects of cue processing. Analyses indicated that participants reporting greater positive, arousing, and social alcohol expectancies rated alcohol cues as more pleasant, arousing, and craving-inducing. In addition, participants displayed inhibited startle reactivity to late alcohol cue probes, indicative of an appetitive reaction. Finally, startle responding to early probes indicated that participants with greater alcohol expectancies displayed blunted attention to negative affect cues. Findings are discussed in terms of the utility of the startle reflex and cue reactivity paradigms for clarifying the relationship between alcohol expectancies and motivated attention to salient cues.

Problematic drinking has been proposed to result from an overactivation of approach motivation toward the beneficial effects of alcohol and an underactivation of avoidance motivation away from aversive consequences of heavy alcohol use. The authors of the present study used a sequential priming task (R. H. Fazio, J. R. Jackson, B. C. Dunton, & C. J. Williams, 1995) to examine the extent to which alcohol cues automatically activate approach and avoidance motivational tendencies in college drinkers. Hierarchical regression analyses indicate that number of binge episodes and alcohol problems are correlated with weak associations between alcohol cues and avoidance motivation but not with strong associations between alcohol cues and approach motivation. Implications for understanding the self-regulation of alcohol use in college drinkers are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Sensation seeking (SS) has traditionally been viewed as a phenomenon of the appetitive motivational system. The limited SS research exploring contributions from the aversive motivational system reveals greater anxious reactivity to dangerous activities among low sensation seekers. The present study extends this line of work by comparing levels of fear and anxiety during anticipation of predictable and unpredictable aversive stimuli across high- and low-SS groups. Low sensation seekers displayed greater fear-potentiated startle (FPS) to predictable aversive stimuli, and only those low on SS showed FPS and skin conductance response effects during experimental contexts in which aversive stimuli were delivered unpredictably. Findings implicate enhanced apprehensive anticipation among those low on SS as a potential deterrent for their participation in intense and threatening stimulus events.

Recent models of alcohol use in youth and young adulthood have incorporated personality change and maturation as causal factors underlying variability in developmental changes in heavy drinking. Whereas these models assume that personality affects alcohol use, the current prospective study tested the converse relation. That is, we tested whether, after accounting for the effect of traits on drinking, collegiate heavy drinking in turn predicted individual differences in change in alcohol-related aspects of personality. We also examined whether affiliation with heavy-drinking peers better accounted for this relation. Following a cohort of recent high school graduates (N = 1,434) through the college years, we found evidence for transactional relations between heavy drinking and changes in impulsivity and sensation seeking. Both traits predicted increases in heavy drinking, but more important, heavy drinking predicted increases in sensation seeking and impulsivity. In final models, social influences did not underlie the effect of heavy drinking on increases in sensation seeking and impulsivity. The results of this investigation suggest that collegiate heavy drinking may negatively and pervasively impact a wide range of behaviors because of its effect on personality change.

The authors examined the effects of alcohol consumption on cigarette craving in heavy smokers and tobacco chippers (n = 138) who were instructed not to smoke for 12 hr. Participants were exposed to both smoking cues (a lit cigarette) and control cues. Half received a moderate dose of alcohol, adjusted for gender, and half received a placebo. Results indicated that alcohol consumption produced an increase in urge-to-smoke ratings before smoking cue exposure. Moreover, during cue exposure, alcohol consumption produced a sharper increase in urge ratings than did the placebo. In addition, during smoking cue exposure, alcohol increased the likelihood of displaying facial expressions associated with positive affect. These findings suggest that alcohol consumption influences both the magnitude and the emotional valence of cigarette cravings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Exposing smokers to either external cues (e.g., pictures of cigarettes) or internal cues (e.g., negative affect induction) can induce urge to smoke and other behavioral and physiological responses. However, little is known about whether the two types of cues interact when presented in close proximity, as is likely the case in the real word. Additionally, potential moderators of cue reactivity have rarely been examined. Finally, few cue-reactivity studies have used representative samples of smokers. In a randomized 2 × 2 crossed factorial between-subjects design, the current study tested the effects of a negative affect cue intended to produce anxiety (speech preparation task) and an external smoking cue on urge and behavioral reactivity in a community sample of adult smokers (N = 175), and whether trait impulsivity moderated the effects. Both types of cues produced main effects on urges to smoke, despite the speech task failing to increase anxiety significantly. The speech task increased smoking urge related to anticipation of negative affect relief, whereas the external smoking cues increased urges related to anticipation of pleasure; however, the cues did not interact. Impulsivity measures predicted urge and other smoking-related variables, but did not moderate cue-reactivity. Results suggest independent rather than synergistic effects of these contributors to smoking motivation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This study investigated the human eyeblink startle reflex as a measure of alcohol cue reactivity. Alcohol-dependent participants early (n?=?36) and late (n?=?34) in abstinence received presentations of alcohol and water cues. Consistent with previous research, greater salivation and higher ratings of urge to drink occurred in response to the alcohol cues. Differential salivary and urge responding to alcohol versus water cues did not vary as a function of abstinence duration. Of special interest was the finding that startle response magnitudes were relatively elevated to alcohol cues, but only in individuals early in abstinence. Affective ratings of alcohol cues suggested that alcohol cues were perceived as aversive. Methodological and theoretical implications of the findings are discussed.

Perceived availability of a substance has been proposed to play a role in cue reactivity by both traditional classical conditioning models and S. T. Tiffany's (1990) cognitive processing model (CPM) of substance use. This study investigated the role of availability information on alcohol cue reactivity. Subjects were 134 heavy drinkers in a 2 × 2 between-subjects design, crossing cues (alcohol vs. neutral) and availability information (availability vs. unavailability). The results indicated significant main effects for cue type, with alcohol cues eliciting greater reactivity on multiple measures, and an interaction effect on the Alcohol Urge Questionnaire (M. J. Bohn, D. D. Krahn, & B. B. Staehler, 1995), such that exposure to alcohol cues in conjunction with unavailability information elicited a greater urge. This was largely a result of changes in self-reported craving and was interpreted as consistent with the CPM. Alternative methodologies and limitations are discussed.

Pavlovian conditioning models have influenced the development of cue exposure treatments for drug abuse. However, poor maintenance of extinction performance (renewal) after treatment is a common problem. A treatment-analogue experiment tested the role of context in renewal, as well as a potential strategy for reducing renewal. Seventy-eight social drinkers completed extinction trials to reduce saliva and urge reactivity to alcohol cues and were randomly assigned to a renewal test in either the same context as extinction, a different context, or the different context containing a cue from the extinction context (E-cue). As predicted, the different context produced greater renewal than the same context and renewal was attenuated when the E-cue was present. These results offer preliminary evidence for the context dependence of extinction to alcohol cues and for the use of an extinction cue to improve the generalizability of exposure therapies.

Little is known about the correlates and potential causes of very early drinking. The authors proposed this risk theory: (a) pubertal onset is associated with increased levels of positive urgency (the tendency to act rashly when experiencing intensely positive mood), negative urgency (the tendency to act rashly when distressed), and sensation seeking; (b) those traits predict increased endorsement of high-risk alcohol expectancies; (c) the expectancies predict drinker status among fifth graders; and (d) the apparent influence of positive urgency, negative urgency, and sensation seeking on drinker status is mediated by alcohol expectancies. The authors conducted a concurrent test of whether the relationships among these variables were consistent with the theory in a sample of 1,843 fifth grade students. In a well-fitting structural model, their hypotheses were supported. Drinker status among fifth graders is not just a function of context and factors external to children: it is predictable from a combination of pubertal status, personality characteristics, and learned alcohol expectancies.

Alcohol use is associated with risks for HIV/AIDS. The association between alcohol and sexual risk may be accounted for by sensation seeking personality. However, sensation seeking in relation to substance use and HIV risk has not been examined in Africa. In this study, 292 men and 219 women receiving sexually transmitted infection (STI) diagnostic and treatment services in Cape Town, South Africa, completed anonymous behavioral surveys. Structural modeling was used to test a model of alcohol use and sensation seeking in relation to sexual risk behaviors. Results showed that sensation seeking and alcohol use in sexual contexts were related to HIV risks, controlling for gender and marital status. The association between sensation seeking and HIV risk was partly accounted for by alcohol use in proximity to sex. In contrast to studies conducted in the United States, sensation seeking was not related to alcohol-sex outcome expectancies. These findings suggest that alcohol use is an important HIV transmission risk factor for many STI clinic patients and that interventions for individuals who are characterized as sensation seekers are urgently needed in South Africa.

The high comorbidity of posttraumatic stress disorder (PTSD) and alcohol dependence (AD) has been firmly established. Although laboratory studies have examined self-reported craving in response to trauma and alcohol cues, no studies have reported on alcohol-related physiological responding in response to trauma cues in PTSD-AD individuals. Using a cue reactivity paradigm, this study examined the impact of personalized trauma-image cues and in vivo alcohol cues on alcohol-related responding (e.g., salivation, craving) in individuals with PTSD and AD (n = 40). Participants displayed reactivity to both trauma and alcohol cues when compared to neutral cues, including increased self-reported craving and distress, as well as greater salivation. These findings suggest that through repeated pairings of trauma memories and alcohol consumption, salivation may become classically conditioned to trauma cues. Moreover, the fact that the trauma-alcohol cue combination elicited greater alcohol craving, salivary responding, distress, and arousal than either the trauma-neutral or neutral-alcohol cue combinations suggests that effects of the trauma and alcohol cues were additive in nature. Evidence that AD individuals with PTSD report increased alcohol craving and display greater salivation in response to trauma memories, supplements prior research indicating that PTSD-related negative emotion and trauma-related alcohol craving may play an important role in the maintenance of AD.

Recent research using event-related potentials (ERPs) has shown that individuals low in alcohol sensitivity show increased P3 reactivity to alcohol cues (Bartholow, Henry, & Lust, 2007). The current research sought to test the specificity of this effect by including other arousing cues in addition to alcohol, and by controlling for individual differences in trait impulsivity. Forty-seven participants varying in self-reported alcohol sensitivity completed a visual oddball task including neutral, arousing (erotic and adventure-related), and beverage-related images while ERPs were recorded. Low-sensitivity participants showed increased P3 reactivity to alcohol cues relative to their high-sensitivity peers. However, P3 amplitude elicited by all other targets did not differ as a function of alcohol sensitivity levels. Differences in impulsivity and recent alcohol consumption did not account for sensitivity group differences in alcohol cue reactivity. These results point to the specific motivational salience of alcohol cues to individuals at risk for alcohol problems because of low alcohol sensitivity and suggest that P3 reactivity to alcohol cues could be a new endophenotype for alcohol use disorder risk.

The acute impairing effects of alcohol on inhibitory control have been well documented in healthy drinkers. By contrast, little is known about alcohol effects in individuals with disorders characterized by poor impulse control, such as those with attention-deficit/hyperactivity disorder (ADHD). Alcohol could produce greater inhibitory impairment in these individuals. The present study tested this hypothesis in adults with ADHD (n = 10) and controls (n = 12) using the cued go/no-go task. The task requires quick responses to go targets and suppression of responses to no-go targets following the presentation of cues. Prior research on healthy adults has shown that valid cues can protect against alcohol impairment (Marczinski & Fillmore, 2003). Performance was tested under 3 doses of alcohol: 0.65 g/kg, 0.45 g/kg, and 0.0 g/kg (placebo). Alcohol dose-dependently increased inhibitory failures in controls in the invalid, but not the valid, cue condition. By contrast, those with ADHD displayed significant alcohol impairment regardless of cue condition. Thus, unlike controls, valid cues offered little protection from the disinhibiting effects of alcohol in drinkers with ADHD, suggesting an increased sensitivity to alcohol impairment of inhibitory control.

Although alcoholics and individuals at risk for alcoholism often show smaller amplitude of the P3 event-related brain potential (ERP), recent data (K. Namkoong, E. Lee, C. H. Lee, B. O. Lee, & S. K. An, 2004) indicate that alcohol-related cues elicit larger P3 amplitude in alcoholics than in controls. Little is known concerning the ERP profiles or alcohol cue reactivity of social drinkers at risk for alcoholism due to low sensitivity to alcohol's effects. Participants differing in alcohol sensitivity viewed images of alcoholic and nonalcoholic beverages while ERPs were recorded and provided information about their alcohol use patterns at baseline and 4 months later. Compared to high-sensitivity participants, those low in sensitivity showed larger P3s to alcohol cues, even when recent alcohol use was statistically controlled for. Moreover, the P3 elicited by alcohol cues predicted alcohol use at follow-up, a finding supporting the idea that P3 amplitude reflects the motivational significance of substance-related cues. These findings point to risk status, not consumption history, as an important predictor of cue reactivity effects. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This experimental study examined effects of alcohol consumption and sexual sensation seeking on unprotected sex intentions, taking into account sexual arousal, indirectly discouraging sex, and condom insistence. Women (N = 173; mean age = 25.02) were randomly assigned to a control, placebo, low-dose beverage (target blood alcohol level = .04), or high- dose beverage (target blood alcohol level = .08) condition. Participants projected themselves into a hypothetical sexual interaction with a man in which no condom was available. Structural equation modeling demonstrated that both sexual sensation seeking and alcohol dose directly increased sexual arousal early in the interaction, but later sexual arousal indirectly increased unprotected sex intentions by decreasing endorsement of indirect discouragement and, in turn, condom insistence. These findings help to clarify the role of alcohol consumption and sensation seeking in women's sexual decision making and point to the importance of examining it as a multistage process.

The mechanisms of naltrexone's effects on urges to drink during abstinence are unclear. Naltrexone may suppress either urges to drink specifically or appetitive responses in general. The effects of naltrexone on cue reactivity to alcoholic and sweet nonalcoholic beverages were investigated. Alcohol-dependent men (N ?=?53) in treatment received naltrexone (50 mg) or placebo. Four hours later, they received baseline assessment, exposure to fruit juice, and exposure to their usual alcoholic beverage in 3-min trials. Naltrexone reduced urge to drink and self-reported attention to the alcohol cues, not at the initial exposure but after repeated exposures to alcohol cues. Naltrexone reduced negative affect across baseline and alcohol trials. No effects of naltrexone on responses to the nonalcoholic appetitive beverage cues were found, suggesting that general appetite suppression does not mediate the effects of naltrexone on urges.

This study examined the effects of alcohol on the ability to execute and inhibit behavior in a context in which preliminary information signaled the likelihood that a response should be executed or suppressed. Adults (N = 24) performed a cued go/no-go task that required quick responses to go targets and suppression of responses to no-go targets. Cue dependency was manipulated by varying the predictive validity of the cues, and performance was tested under 3 doses of alcohol: 0.00 g/kg, 0.45 g/kg, and 0.65 g/kg. Dose-dependent increases in cue dependence were only observed with highly predictive cues. Results suggest that alcohol-induced increases in stimulus control over behavior might be most likely in situations when stimulus control over behavior has already been established.

The present study explores the relation among 4 personality traits associated with impulsive behavior and alcohol abuse. Personality traits were measured using the 4 subscales of the UPPS Impulsive Behavior Scale (UPPS: S. P. Whiteside & D. R. Lynam. 2001). The UPPS and measures of psychopathology were administered to clinical samples of alcohol abusers high in antisocial personality traits (AAPD), alcohol abusers low in antisocial personality traits (AA), and a control group (total N = 60). Separate analyses of variance indicated that AAPDs had significant elevations on all 4 UPPS scales, whereas the AAs and controls differed only on the Urgency subscale. However, when controlling for psychopathology, group differences on the UPPS scales disappeared. The results suggest that personality traits related to impulsive behavior are not directly related to alcohol abuse but rather are associated with the elevated levels of psychopathology found in a subtype of alcohol abusers.

Some individuals may have an inherent reactivity to alcohol that facilitates early development of characteristics associated with alcoholism. Although response to alcohol cues has been used to assess this reactivity, few studies have included women or investigated familial alcoholism as a variable. In this study, 23 female college students were divided into groups according to family history of alcoholism (positive or negative). Alcohol reactivity was measured by salivation, skin temperature, heart rate, mood state, and craving for alcohol following presentation of alcohol-related and neutral cues. Results indicate no correlation between salivary reactivity and alcohol craving, which suggests that these variables tap into different domains of cue reactivity. Findings demonstrate that alcohol cue reactivity can be assessed in female social drinkers and that familial alcoholism may influence salivary reactivity to alcohol-related cues.
