Alcohol expectancy priming and drinking behavior: The role of compatibility between prime and expectancy content.

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.

Effects of priming positive and negative outcomes on drinking responses.

Studied the effects of priming positive and negative expectancy outcomes on the drinking responses of college students. Men and women (N?=?64; mean age 19.5 yrs) were randomly assigned to 1 of 3 priming conditions: a positive expectancy outcome condition, a negative expectancy outcome condition, and a neutral (control) condition. Participants were exposed to a series of semantic primes corresponding to their condition and then asked to complete a beer taste-rating task. Planned comparisons revealed that the average ratio of beer consumed to body weight in the positive condition was significantly greater than the average ratio in the neutral condition, and the average ratio of beer consumed to body weight was significantly less in the negative condition than the average ratio in the neutral condition. These findings are discussed as they relate to cognitive models of alcohol use. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Use of two-segmented logistic regression to estimate change-points in epidemiologic studies

The effects of exposure to an alcohol-related cue (drinking low-alcohol beer) and a musical depression/elation mood induction procedure, on craving, motivation and liking for alcohol, were studied in male and female recreational drinkers. Alcohol craving was assessed using the multidimensional desires for alcohol questionnaire (DAQ), motivation for alcohol was assessed by performance on a progressive ratio (PR) task reinforced with small volumes (25 ml) of low-alcohol beer, and liking for the reinforcers earned in the PR task was assessed using a visual analogue scale. Consumption of a half-pint of low-alcohol beer increased alcohol craving in male subjects but had no effect or decreased craving in female subjects. Subsequent induction of a depressed mood increased craving scores, relative to elated or neutral mood groups, but these effects were confined to abstinent (non-cued) subjects, both male and female. Performance on the PR task correlated significantly with one of the four factors of the DAQ, negative reinforcement, and was increased by induction of a depressed mood in abstinent female and cued male subjects. Reinforcer liking was unchanged following mood induction in male subjects, but decreased in both groups of female subjects. To summarize, the cue of drinking low-alcohol beer increased alcohol craving in men but not in women, and induction of a depressed mood increased alcohol craving and motivation, but also decreased alcohol liking. These effects were present to different extents in different cue/gender subgroups, and were partially independent.     

Experimental demonstration of the influence of alcohol advertising on the activation of alcohol expectancies in memory among fourth-and fifth-grade children.

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.

Alcohol primes, expectancies, and the working self-concept.

Previous research has shown that alcohol consumption can lead to momentary changes in the self-concept (e.g., Steele & Josephs, 1990). In two studies (n = 150), we examined whether the implicit activation of alcohol expectancies (i.e., sociability-related expectancies) would also lead to changes in self-perception. To test this idea, participants first completed a measure of sociability-related alcohol expectancies. In a subsequent laboratory session, participants were exposed to either alcohol-related primes (i.e., pictures or words associated with alcohol) or neutral primes. After the priming task, participants completed an ostensibly unrelated self-concept survey that contained words related to sociability (e.g., “outgoing”) and nonsociability related words (e.g., “clever”). For both studies, results revealed that sociability-related alcohol expectancies were positively associated with sociability-related self-concept ratings for participants exposed to alcohol primes, but not for participants exposed to the neutral primes. Implications for the role implicit self-concept activation may have on drinking behaviors are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influence of naltrexone on cue-elicited craving among hazardous drinkers: The moderational role of positive outcome expectancies.

This study was designed to elucidate mechanisms by which naltrexone (NTX) influences drinking among hazardous drinkers. Thirty-six hazardous drinkers received 50 mg NTX or placebo on 2 separate occasions before participation in a taste test procedure with low-alcohol beer. Urges to drink before consumption, beer volume consumed, and perceived stimulation and sedation after consumption were assessed. Although NTX did not influence beer consumption, hazardous drinkers who reported high positive reinforcement expectancies rated their urges to drink as significantly lower when they were on NTX compared with placebo. Positive outcome expectancies also moderated the effects of NTX on subjective reports of stimulation following drinking. These findings suggest that naltrexone may be particularly effective at reducing alcohol cue-elicited positive reinforcement for those with high positive alcohol outcome expectancies.

Alcohol intake and cognitive abilities in old age: The Lothian Birth Cohort 1936 study.

Objective: Moderate alcohol consumption has been associated with better cognitive performance in late adulthood, possibly by improving vascular health. Few studies have examined the potentially confounding roles of prior cognitive ability and social class in this relationship. Method: Participants were 922 healthy adults about 70 years old in the Lothian Birth Cohort 1936 study, for whom there are IQ data from age 11. Alcohol consumption was obtained by self-report questionnaire. Cognitive outcome measures included general cognitive ability, speed of information processing, memory, and verbal ability. Results: Moderate to substantial drinking (>2 units/day) was associated with better performance on cognitive tests than low-level drinking (≤2 units/day) or nondrinking in men and women. After adjusting for childhood IQ and adult social class, most of these associations were removed or substantially attenuated. After full adjustment, a small, positive association remained between overall alcohol intake and memory (women and men) and verbal ability (women only). Women's overall alcohol intake was derived almost exclusively from wine. In men, effects differed according to beverage type: wine and sherry–port consumption was associated with better verbal ability, but beer was associated with a poorer verbal ability and spirits intake was associated with better memory. Conclusions: Prior intelligence and socioeconomic status influence both amount and type of alcohol intake and may partly explain the link between alcohol intake and improved cognitive performance at age 70. Alcohol consumption was found to make a small, independent contribution to memory performance and verbal ability, but these findings' clinical significance is uncertain.

Automatic guidance of visual attention from verbal working memory.

Previous studies have shown that visual attention can be captured by stimuli matching the contents of working memory (WM). Here, the authors assessed the nature of the representation that mediates the guidance of visual attention from WM. Observers were presented with either verbal or visual primes (to hold in memory, Experiment 1; to verbalize, Experiment 2; or merely to attend, Experiment 3) and subsequently were required to search for a target among different distractors, each embedded within a colored shape. In half of the trials, an object in the search array matched the prime, but this object never contained the target. Despite this, search was impaired relative to a neutral baseline in which the prime and search displays did not match. An interesting finding is that verbal primes were effective in generating the effects, and verbalization of visual primes elicited similar effects to those elicited when primes were held in WM. However, the effects were absent when primes were only attended. The data suggest that there is automatic encoding into WM when items are verbalized and that verbal as well as visual WM can guide visual attention.

The influence of alcohol expectancy priming and mood manipulation on subsequent alcohol consumption.

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.

Implicit stereotyping in person judgment.

Three experiments demonstrated implicit gender stereotyping. A target's social category determined the use of previously primed stereotyped information, without Ss' awareness of such influence. After unscrambling sentences describing neutral or stereotyped behaviors about dependence or aggression, Ss evaluated a female or male target. Although ratings of female and male targets did not differ after exposure to neutral primes, Ss exposed to dependence primes rated a female target as more dependent than a male target who performed identical behaviors (Exp 1A). Likewise, Ss rated a male, but not a female, target as more aggressive after exposure to aggression primes compared with neutral primes (Exp 1B). Exp 2 replicated the implicit stereotyping effect and additionally showed no relationship between explicit memory for primes and judgment of target's dependence.

Rhyme priming of pictures and words: A lexical activation account.

Orthographically/phonologically related primes have typically been found to facilitate processing of target words. This phenomenon is usually explained in terms of spreading activation between nodes for orthographically/phonologically similar words in lexical memory. The phenomenon was explored in a series of studies involving the manipulations of prime and target type (word or picture) and prime and target task (naming or categorization). Generally, the results support the lexical activation explanation. Named primes, which activate lexical memory, facilitate processing in all target tasks involving lexical access (word and picture naming and word categorization), independent of prime type. Categorized primes show the expected Prime Type?×?Relatedness interaction with word primes, which activate lexical memory, producing much more facilitation than picture primes. Finally, unlike in semantic priming studies, increased depth of processing of a word prime decreased the size of the priming effects. Apparently, initial activation levels in lexical memory are not maintained when semantic processing of the prime is required. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol consumption and the 5-year incidence of age-related maculopathy: the Beaver Dam eye study

OBJECTIVE: This study evaluated alcohol consumption as a risk factor for incidence of age-related maculopathy (ARM). DESIGN: Persons aged 43 to 86 years in 1988 in Beaver Dam, Wisconsin, were examined from 1988 through 1990 and 1993 through 1995, n = 3684. The presence and severity of ARM at both examinations were determined from gradings of stereoscopic fundus photographs using the Wisconsin Age-related Maculopathy Classification System. Alcohol consumption was determined by self-report. RESULTS: Men drinking at least 78 g/week of alcohol from beer had a higher 5-year age-adjusted incidence of early ARM (10.6%) than did men who did not drink beer (6.9%), but the test for trend was only borderline significant (P = 0.08). However, incidence of soft indistinct drusen (P = 0.01), increased drusen area (P < 0.01), and confluent drusen (P = 0.02) are all associated with beer drinking in men. Increased retinal pigment and retinal pigment epithelial depigmentation are not associated with beer drinking in men or women nor are any lesions associated with total alcohol consumption or consumption from liquor or wine in either men or women. CONCLUSIONS: Except for an association of beer drinking with retinal drusen in men, consumption of alcoholic beverages is not likely to be an important risk factor for incidence of ARM.     

Memory association and personality as predictors of alcohol use: mediation and moderator effects

We investigated the nature of the effects of memory associations on alcohol use and abuse. First, we determined if effects of memory associations on drinking problems are mediated entirely through the frequency of alcohol consumption or, alternatively, if such effects are more direct. Second, personality traits were assessed to evaluate whether they were confounded with memory association in their effects or whether they might moderate the effects of memory associations on alcohol use and abuse. The results showed that memory association measures directly and independently predicted alcohol consumption; these measures indirectly predicted problems from drinking, including drunk driving. None of the assessed personality variables moderated the predictive effects of memory association. The results are consistent with the view that memory associations influence behavior through cognitive processes that are not affected by personality traits or by cognitions emanating from such traits.     

Positive mood + action = negative mood + inaction: Effects of general action and inaction concepts on decisions and performance as a function of affect.

General action and inaction concepts have been shown to produce broad, goal-mediated effects on cognitive and motor activity irrespective of the type of activity. The current research tested a model in which action and inaction goals interact with the valence of incidental moods to guide behavior. Over four experiments, participants' moods were manipulated to be positive (happy), neutral, or negative (angry or sad), and then general action, inaction, and neutral concepts were primed. In Experiment 1, action primes increased intellectual performance when participants experienced a positive (happy) or neutral mood, whereas inaction primes increased performance when participants experienced a negative (angry) mood. Including a control-prime condition, Experiments 2 and 3 replicated these results measuring the number of general interest articles participants were willing to read and participants' memory for pictures of celebrities. Experiment 4 replicated the results comparing happiness with sadness and suggested that the effect of the prime's adoption was automatic. Overall, the findings supported an interactive model by which action concepts and positive affect produce the same increases in active behavior as inaction concepts and negative affect.

Interactive effects of alcohol outcome expectancies and alcohol cues on nonconsumptive behavior.

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.

Positive responses to televised beer advertisements associated with drinking and problems reported by 18 to 29-year-olds

AIMS: To examine the nature of the relationships between responses to alcohol advertisements and drinking behaviour and related problems. To examine the role of positive and negative beliefs about drinking as intervening variables. DESIGN: Survey utilizing a CATI (computer-assisted telephone interviewing) system, involving interviews with 1012 randomly selected respondents. SETTING: Respondents were randomly selected from throughout New Zealand. PARTICIPANTS: Eighteen to twenty-nine-year-old New Zealanders. MEASUREMENTS: Response to specific alcohol advertisements was measured by recalled exposure (how often they recalled having seen the advertisements) and liking (a measure of positive response). FINDINGS: An exploratory non-recursive structural equation model, based on 791 drinkers provided tentative support for the hypothesis that positive responses to televised beer advertisements (as measured by liking) contributed to the quantity of alcohol consumed on drinking occasions, which in turn contributed to the level of alcohol-related problems. The model, which provided a good fit to the data, was consistent with the hypothesis that liking of beer advertisements had both a direct influence on quantities of alcohol consumed and an indirect influence, via its influence on positive beliefs. These effects were present after controlling for reciprocal effects, none of which were significant. The data did not support the hypothesis that the quantities of alcohol consumed would influence the respondent's liking of beer advertisements. Recalled exposure was not a significant influence on the quantities consumed. CONCLUSIONS: The results are consistent with a number of theoretical perspectives and with a growing body of research that are suggestive of alcohol advertising having some influence on the consumption of younger people.     

Forget "drinking to forget": Enhanced consolidation of emotionally charged memory by alcohol.

Social drinkers (42 men, 18-34 years old) participated in a study of the effects of alcohol consumption on incidental memory for emotionally salient verbal stimuli. Participants rated depressing, elating, and neutral statements while sober. Fifteen minutes later they consumed alcohol or active placebo (1.0 or 0.1 ml/kg) in an environment with minimal retrograde interference. In surprise memory testing 24 hr later, when participants were again sober, the alcohol group had increased recall across statement type. The alcohol group also had better recognition of depressing and elating statements, but recognition of neutral statements did not differ between groups. Findings suggest alcohol produced a nonspecific enhancement of incidental memory and that alcohol's motivational properties were not implicated.

Parental alcoholism and the effects of alcohol on mediated semantic priming.

In this study, researchers tested the effects of a moderate dose of alcohol on the spread of activation of associated information in memory using a mediated semantic priming task in which target words are preceded by primes that are either unrelated or indirectly related to the target. Male and female participants with or without a parental history (PH+ and PH-, respectively) of alcoholism were administered the priming task after consuming alcohol or a placebo beverage. Among PH- individuals, alcohol constrained the spread of activation of associated information, as manifested by a reduced priming effect. In contrast, alcohol enhanced priming effects among PH+ participants, though this latter effect appears to be due to a particularly slow response among these individuals to unprimed words. Results are discussed with regard to theories of alcohol's effects on cognitive processes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Empirical modeling of an alcohol expectancy memory network using multidimensional scaling.

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.

Is physical activity or aerobic power more influential on reducing cardiovascular disease risk factors?

AIMS: The chief purpose of the current study was to assess whether young children endorse expectancies specific to alcohol. DESIGN: In order to accomplish this aim, a 2 (gender of child) by 2 (gender of adult drinker) by 2 (grade level) by 2 (beverage type) repeated measure design was employed with beverage type as the repeated measure. SETTING: Data were collected within elementary schools located in two Midwestern states. PARTICIPANTS: One hundred and twenty-four second and third graders (42% male) participated in individually structured interviews. MEASUREMENTS: The expectancy interview was based on the Children's Alcohol-Related Expectancy Questionnaire and assessed each child's beliefs about the desirable and undesirable consequences which adult men and women might experience after drinking alcohol (beer) and a control beverage (iced tea). FINDINGS: The results indicated that children endorsed significantly more undesirable expectancies for beer than for iced tea, and more desirable expectancies for iced tea than for beer. In addition, children's expectancies varied as a function of the gender of the drinker. Specifically, both second- and third-graders expected more undesirable outcomes for women than for men, and second graders expected fewer desirable outcomes for women than for men, regardless of beverage. CONCLUSIONS: Prior to substantial experience with alcohol consumption, children have already developed expectancies for alcohol. Specifically, young elementary children endorse predominantly undesirable expectancies for beer.
