Expectations about the effects of alcohol have been modeled as stored memories. This study tested the memory view for investigating the processes that influence drinking. Strategies taken from recent memory research were used to implicitly prime drinking. Consequent effects on consumption of a commercial nonalcoholic beer were measured. Participants were led to believe this beer contained alcohol. Eighty undergraduate women (n?=?20 per cell) participated in 2, apparently unrelated, studies. A 2?×?2 factorial design simultaneously varied videotaped primes (bar setting or neutral video) with semantic primes (expectancy or neutral words). Women exposed to unobtrusive alcohol primes of either type drank significantly greater amounts (p?  相似文献

An accumulating literature has shown the influence of childhood experiences associated with alcohol use on later drinking practices. Recent studies have suggested that alcohol-related expectancy may serve as an intervening variable to connect these early experiences with the later, proximal decision to drink when opportunities for actual alcohol consumption arise. Those studies, however, have collected expectancy and drinking data concurrently, whereas the present study for the first time reports on the power of expectancies measured in early adolescents (seventh and eighth grades) to predict self-reported drinking onset and drinking behavior measured a full year later. Results show that five of seven expectancy scores readily discriminated between nonproblem drinkers and those subsequently beginning problem drinking and accounted for a large portion of the variance in a continuous quantity/frequency index and a problem drinking index. The strength of these time-lagged relations strengthens the case for inferring that expectancies have causal power on drinking behavior and suggests prevention strategies.

According to information-processing models of alcohol use, alcohol expectancies constitute representations in long-term memory that may be activated in the presence of drinking-related cues, thereby influencing alcohol consumption. A fundamental implication of this approach is that primed expectancies should affect drinking only for those individuals who possess the specific expectancies primed. To test this notion, in the present study, participants were initially assessed on 3 distinct domains of positive alcohol expectancies. Approximately 1 week later, they completed an ad libitum drinking study during which only a single expectancy domain (sociability) was primed in the experimental condition. Consistent with predictions, following exposure to sociability primes but not control primes, individuals with stronger expectancies that alcohol would enhance sociability uniquely showed increased placebo consumption of nonalcoholic beer. These results, which demonstrate the moderating role of compatibility between the specific content of primes and that of underlying expectancies, offer new, direct support for memory network-based models of drinking behavior.

The utility of trait social anxiety and alcohol expectancies in predicting increased alcohol consumption under socially stressful conditions was investigated. Forty-two male and 42 female undergraduates participated in a 2-day study, serving as their own controls. In each session, participants consumed their preferred alcoholic beverage during a 30-min drinking period. The lst session established baseline consumption under nonstressful conditions, while in the 2nd session, participants drank while anticipating the required delivery of a speech. Measures of social anxiety and alcohol expectancies were completed. Participants consumed more absolute alcohol during the stressful session, but those with high trait social anxiety and men expecting alcohol to increase assertiveness were most likely to show this effect. These findings suggest specificity in the connection between individual characteristics and stress-induced drinking. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Nonlinear and interactive models of alcohol expectancies and drinking were investigated using survey data obtained from junior and senior high school students on 2 occasions 2 years apart. Significant nonlinear and interactive effects were found in cross-sectional analyses. First, negative expectancies were most predictive when subjective likelihood was low. Second, drinking was highest when respondents believed that (a) negative consequences were unlikely and affective enhancement was likely and (b) both affective enhancement and social facilitation were likely. A simpler linear model was adequate for predicting changes in drinking, with both negative and affective enhancement expectancies having significant longitudinal effects. The results support the importance of alcohol expectancies but suggest that the relationships between these beliefs and adolescent drinking may be complex.

Alcohol expectancies are theorized to operate through associative memory networks. These networks are thought to differ on the basis of individual experience (direct and vicarious) with alcohol. Free-associate probabilities have been used in cognitive psychology as a metric of the associative strength of words to other words; this method has been used to establish the relationships within a semantic memory network. Participants from a large college sample were asked to free associate to the phrase "Alcohol makes me______" They were also asked about their quantity of alcohol consumption. Results showed that specific responses were given with different probabilities by individuals who drank at different levels. The heaviest drinkers tended to have more positive and arousing responses than did lighter drinkers, who tended to have more negative and sedating responses. These results underscore the need to take into account relevant individual differences in behavior and experience when characterizing semantic networks.

Memory model-based expectancy studies have shed light on the process by which expectancies may influence drinking but have not related changes in expectancy activation to drinking changes. In the present study, 38 undergraduates completed a drinking measure and factor-based and memory model-based expectancy measures, before and after an expectancy challenge intervention designed to alter expectancies. Expectancies were mapped into memory network format with individual differences scaling and likely paths of activation were modeled with preference mapping. Results indicated that exposure to the expectancy challenge led to a change in likely activation of expectancies for men, but not for women. In the 30 days after the intervention, alcohol use among men decreased significantly but did not change among women. Therefore, changes in likely activation corresponded to changes in drinking. These findings support a memory model conceptualization of expectancy influence on drinking. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Studies showing that verbal priming can implicitly affect alcohol consumption have been used to support cognitive models of expectancies. However, because expectancy words reflect affective states as well as drinking outcomes, mediation through an affective pathway remains theoretically plausible (i.e., such words inadvertently may affect mood, which in turn influences drinking). The primary pathway was identified (and expectancy theory was tested) by comparing memory priming (using alcohol expectancy or neutral words) with mood induction (using positive or neutral music); an unrelated experiment paradigm allowed the priming manipulation to implicitly affect drinking. Men in the alcohol priming group drank significantly more than men in each of the other conditions, and, consistent with theory, men with histories of heavier drinking drank the most when primed with alcohol expectancies, indicating that expectancies can function as automatic memory processes.

Increased understanding of how risk-related variables influence later alcohol use and alcoholism requires a shift from identifying correlated variables to developing models of mediational processes. Memory operation, with alcohol expectancies as critical content, is one such model. To explicate this model, similarity judgment, which is well established for discerning memory organization, was used. Euclidean distance-based algorithms, including multidimensional scaling and hierarchical clustering, were then used to empirically specify memory structures and processes as a function of individual differences in drinking. The resulting semantic networks support previous findings and show for the first time that heavy drinkers' networks may be more tightly configured than those of light drinkers. These findings bring researchers closer to a computational model of the psychopharmacological process that governs drinking. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Increased expectations of positive effects of alcohol have been associated with severity of drinking across a variety of abusing and nonabusing adult populations. Although alcohol expectancies have been examined among high school adolescents, no study has examined expectancies of identified adolescent abusers in treatment. This study investigated whether adolescent alcohol abusers in treatment expect significantly more reinforcement from alcohol than do nonabusing peers and whether expectancies vary as a function of exposure to parental alcohol abuse. The adolescent version of the Alcohol Expectancy Questionnaire (Christiansen, Goldman, & Inn, 1982) was completed by 116 abusing and nonabusing adolescents. Results indicate that adolescent alcohol abusers expect significantly more reinforcement from alcohol than do demographically comparable nonabusing peers. Adolescents with an alcohol-abusing parent reported expecting more cognitive and motor enhancement from drinking than did adolescents without a family history of abuse. Thus, both personal alcohol use and parental alcohol use are related to adolescent alcohol expectancies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Experimental research and popular belief suggest that, among its many effects, alcohol consumption reduces tension and facilitates aggression. Such observations could result from direct, pharmacological effects of alcohol on neural control of behavior but also may be accounted for by positing that drinking behavior activates mental representations of relaxation-related or aggression-related alcohol expectancies in long-term memory. Building on this latter view, in 2 experiments, the authors investigated whether rudimentary drinking-related cues, which presumably activate encoded alcohol expectancies, facilitate tension reduction and hostility in the complete absence of actual or placebo alcohol consumption. In Experiment 1, following contextual exposure to alcohol-related words, individuals with stronger expectancies that drinking reduces tension showed an increased willingness to meet with an opposite-gender stranger under relatively anxiety-provoking circumstances, suggesting that they experienced less apprehension regarding the meeting. Analogously, in Experiment 2, following near-subliminal exposure to alcohol-related words, individuals with stronger expectancies that drinking fosters aggression showed greater hostility toward a target person following an experimentally engineered provocation. Neither of the latter effects was obtained following exposure to nonalcoholic beverage words, which presumably did not activate alcohol outcome expectancy representations in long-term memory. Moreover, the strength of relevant, content-specific expectancies (i.e., for tension reduction or aggression, respectively) moderated alcohol cue exposure effects, but the strength of other expectancies (e.g., for sociability or sexual arousal) did not. Together, these findings demonstrate that exposure to rudimentary alcohol cues independently engenders expectancy-consistent behavior, thereby attesting to the remarkable breadth and subtlety of the behavioral impact of alcohol expectancy activation.

Compared the reinforcement expectancies of adult alcoholics with beliefs of 2 other adult populations. 171 participants (mean age 42.8 yrs) in alcohol treatment programs, 65 hospitalized medical patients (mean age 42.6 yrs), and 344 college students (mean age 24 yrs) identified their beliefs about the consequences of alcohol consumption through an alcohol expectancy questionnaire (AEQ). Results indicate that the previously defined AEQ beliefs among nonalcoholic populations identified by S. A. Brown et al (1980) and B. A. Christiansen et al (see record 1982-25609-001) are applicable to alcoholic populations. In the present study, nonalcoholics and alcoholics differed significantly in terms of their alcohol expectancies. In general, alcoholics were found to maintain strong alcohol expectancies, and expectancies increased across and within populations as a function of drinking patterns. Theoretical, research, and clinical implications of these findings and the AEQ are discussed. (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Previous work has demonstrated that children's organization and activation of alcohol expectancies in memory vary as a function of alcohol use, even among children as young as in the 3rd grade. To advance the understanding of influences on the development of alcohol expectancies in children, 551 4th- and 5th-grade children were exposed to 5 beer commercials or 5 soft drink commercials. After viewing the advertisements, all children reported their 1st associate to an alcohol prompt and completed a memory model-based measure of children's alcohol expectancies. Multidimensional scaling was used to map expectancies into hypothetical memory network format, and preference mapping was used to derive possible paths of activation. Children who viewed beer commercials were more likely to activate positive and amusing alcohol expectancies. In view of previous findings demonstrating that this pattern of activation corresponded to higher drinking among 3rd, 6th, 9th, and 12th graders, the present findings suggested that antecedents to drinking like exposure to advertising may promote heavier drinking among children by influencing the activation of expectancies in memory.

Used a measure developed by K. H. Dermen and M. L. Cooper (see record 1995-07934-001) to test the relationship between sex-related alcohol expectancies and drinking in social and sexual situations among a representative sample of 874 sexually experienced adolescents (aged 13–19 yrs) who had ever consumed alcohol. Regression analyses (in which demographics and a global measure of drinking were controlled for) revealed that sex-related alcohol expectancies were better predictors of drinking in sexual situations than were general alcohol expectancies, whereas the reverse was true for drinking in social situations. Different expectancies predicted whether respondents drank in these situations as compared with the frequency of drinking to intoxication in the same situations. Results highlight the value of assessing domain-specific alcohol expectancies when predicting alcohol use in particular situations.

Expectancies' mediational (control) role in alcohol consumption has been supported by both correlational and experimental evidence (J. Darkes & M. S. Goldman, 1993; M. S. Goldman, P. E. Greenbaum, & J. Darkes, 1997; L. Roehrich & M. S. Goldman, 1995). This study assigned participants (n?=?54) to 1 of 2 expectancy challenges targeting the expectancy dimensions of either arousal or sociability identified by B. C. Rather and M. S. Goldman (1994), or to a no-treatment control, to examine the relationship of the structure and process of change in alcohol expectancies. Both challenges resulted in reduced consumption and expectancies immediately posttreatment and 6 weeks later after a short "booster" session. These results may reflect the lack of "discrete" expectancy structure and provide further support for the exploration of these methods as a possible prevention strategy.

We examined the within-person relationships between daily work stressors and alcohol consumption over 14 consecutive days in a sample of 106 employed college students. Using a tension reduction theoretical framework, we predicted that exposure to work stressors would increase alcohol consumption by employed college students, particularly for men and those with stronger daily expectancies about the tension reducing properties of alcohol. After controlling for day of the week, we found that hours worked were positively related to number of drinks consumed. Workload was unrelated to alcohol consumption, and work-school conflict was negatively related to consumption, particularly when students expressed strong beliefs in the tension reducing properties of alcohol. There was no evidence that the effects of work stressors were moderated by sex. The results illustrate that employment during the academic year plays a significant role in college student drinking and suggest that the employment context may be an appropriate intervention site to address the problem of student drinking.

Attempts to understand the mechanism by which alcohol expectancies might influence drinking have related activation of expectancies in memory to alcohol use. Limb of the blood alcohol curve, however, has not been considered. In the present study, 527 undergraduates completed the Anticipated Biphasic Alcohol Effects Scale and a drinking measure. Multidimensional scaling was used to map expectancies into memory network format, and likely activation of expectancies was empirically modeled. Heavier drinkers were most likely to activate positive and arousing expectancies associated with the ascending limb, whereas lighter drinkers were most likely to activate negative and sedating expectancies associated with the descending limb. These findings add to the literature suggesting that activation of expectancies in memory may be an important determinant of drinking behavior and a promising target for intervention strategies.

Risk-related antecedent variables can be linked to later alcohol consumption by memory processes, and alcohol expectancies may be one relevant memory content. To advance research in this area, it would be useful to apply current memory models such as semantic network theory to explain drinking decision processes. Multidimensional scaling (MDS) was used to empirically model a preliminary alcohol expectancy semantic network, from which a theoretical account of drinking decision making was generated. Subanalyses showed how individuals with differing alcohol consumption histories may have had different association pathways within the expectancy network. These pathways may have in turn influenced future drinking levels and behaviors while the person was under the influence of alcohol. All individuals associated positive/prosocial effects with drinking, but heavier drinkers indicated arousing effects as their highest probability associates, whereas light drinkers expected sedation. An important early step in this MDS modeling process is the determination of iso-meaning expectancy adjective groups, which correspond to theoretical network nodes.

288 adults and 265 university students responded to a questionnaire concerning beliefs about the effects of alcohol, which included a measure of evaluation of alcohol effects. Analyses were performed with measures of frequency of drinking episodes, usual quantity consumed/episode, frequency of intoxication and consumption of 8 or more drinks at one sitting, and estimated number of drinks per year. Evaluation of the undesirable consequences of drinking added significantly to the prediction of quantity-based drinking variables. It is suggested that perceived desirability of alcohol effects is an important factor in understanding the relationship of expectancies to drinking.
