Alcohol's effects on physiological arousal and self-reported affect and sensations.

60 male normal drinkers (undergraduates) were instructed that they would receive an alcoholic, nonalcoholic, or an unidentified beverage that would be alcoholic or nonalcoholic. Half the Ss in each instruction group consumed an alcoholic beverage; the other half consumed a non-alcoholic beverage. Self-reports of affect (Mood Adjective Check List, Multiple Affect Adjective Check List) and bodily sensations and measures of pulse rate and skin conductance were obtained at baseline and during the ascending and descending phases of the blood alcohol concentration (BAC) function. Analysis of covariance showed that Ss who consumed alcohol reported higher levels of positive affects and sensations and lower levels of depression than Ss who did not consume alcohol. The instructional manipulation had a limited effect. Self-reports of affect and sensations were most affected by type of beverage consumed; sensations were also rated higher during the ascending than during the descending phase of the BAC. Physiological measures were influenced by instructions and beverage. (40 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Loss of control drinking in alcoholics: An experimental analogue.

Presented 2 groups of 32 male 23-65 yr old nonabstinent alcoholics and social drinkers with an ad-lib supply of either alcoholic or nonalcoholic beverages in a taste-rating task. Ss were assigned to 1 of 2 instructional set conditions in which they were led to expect that the beverage to be rated contained alcohol (vodka and tonic) or consisted only of tonic. The actual beverage administered consisted of either vodka and tonic or tonic only. Results show that instructional set is a significant determinant of the amount of beverage consumed and posttask estimates of the alcoholic content of the drinks. The actual beverage administered did not significantly affect the drinking rates of either alcoholics or social drinkers. Loss-of-control drinking, in the form of increased consumption by alcoholics who were administered alcohol, did not occur during the drinking task. Results are discussed in terms of implications for treatment and for the conception of alcoholism as a disease. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Expectancies, alcohol, and sexual arousal in male social drinkers.

Randomly assigned 40 undergraduate males, all social drinkers, to 1 of 2 expectation conditions in which they were led to believe that the beverage they were administered contained either vodka and tonic or tonic only. For half of the Ss in each expectation condition, the beverage contained vodka; the others drank only tonic. After their drinks, measures of penile tumescence were taken from Ss using a penile strain gauge during 2 erotic films, 1 depicting a heterosexual interaction, the other a male homosexual interaction. Although analyses of variance failed to reveal any effect of alcohol per se, there were significant effects of expectation on penile tumescence during both the heterosexual and homosexual films. Ss who believed that they had consumed an alcoholic beverage manifested significantly greater sexual arousal than those believing they had consumed a nonalcoholic beverage, regardless of the contents of their drinks. Although no consistent effects were observed on additional measures of sexual arousal, including the TAT, the Word Association Test, and forehead skin temperature, there was a significant positive correlation between self-report measures of sexual arousal and penile tumescence.

Alcohol, sexual arousal, and self-control.

Investigated the effects of alcohol on self-regulation using delay of gratification for viewing time for an erotic film as the primary dependent measure. Other measures included reflection–impulsivity, locus of control, sexual-guilt scores, and continuous recording of Ss' penile tumescence. Using a balanced placebo design with 50 undergraduate men, Ss were led to believe that they had consumed an alcoholic or a nonalcoholic beverage, and half of each of these 2 groups received either alcohol or tonic water. In addition, the effects of 3 doses of alcohol (placebo, low dose, high dose) were investigated. Instructional set, regardless of drink content, resulted in longer delay times and increased thoughts with sexual content. Although there was no significant relation between increasing dose of alcohol and delay time, there was an interaction between scores on Rotter's Internal–External Locus of Control Scale and alcohol dose. Externalizers showed an inverse linear relation between increasing dose of alcohol and delay time. Internalizers showed the opposite trend. Results support other research showing that expectations about drinking can be more potent predictors of behavior than the pharmacological impact of alcohol. Implications for the self-regulation of sexual behavior under the influence of alcohol are discussed. (25 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of alcohol and cognitive set on sexual arousal to deviant stimuli.

48 undergraduate male social drinkers were randomly assigned to 1 of 2 expectancy set conditions in which they were led to believe that the beverage they were administered contained alcohol or no alcohol. For half of the Ss in each expectancy condition, the beverage was an alcoholic malt liquor; the others drank a nonalcoholic malt beverage. After their drinks, changes in penile tumescence (PT) in response to normal and deviant tape recordings and to self-generated fantasy were measured physiologically by a mercury-in-rubber strain gauge. The cognitive set (expectancy) significantly increased PT in response to the various erotic recordings. Alcohol did not significantly influence levels of sexual arousal. Ss who believed they had consumed an alcoholic beverage evidenced significantly more arousal to the forcible rape recording and to the sadistic stimuli than Ss who believed that they had consumed a nonalcoholic beverage, regardless of the actual contents of the beverage. The cognitive set, as well as the alcohol, significantly influenced heart rate, skin temperature, and subjective reports of sexual arousal. Self-report measures of sexual arousal were positively correlated with PT. Mosher Forced-Choice Guilt Inventory scores were not significantly correlated with PT, although the Sex Guilt subscore was negatively correlated with the subjective measure of sexual arousal for the heterosexual intercourse and forcible rape tapes.

Effects of alcohol on social anxiety in women: Cognitive versus physiological processes.

Randomly assigned 32 female social drinkers (18–25 yr old undergraduates) to 4 conditions in a 2?×?2 factorial design that controlled for drink content and expectations. Ss were administered either an alcoholic or a nonalcoholic beverage and were led to believe that their drinks contained or did not contain alcohol. After finishing their drinks Ss participated in a study of social anxiety in which they were requested to interact with a male confederate of the experimenter. Multiple measures, including heart rate, skin conductance, and overt behavioral and self-report responses, were recorded. Ss who expected alcohol showed significant elevations in physiological arousal and were rated as more anxious on observational measures of social behavior. Self-report measures failed to yield any differences among groups. Implications for the tension reduction theory of alcohol use and the importance of multiple response measures are discussed.

Alcohol consumption as a self-handicapping strategy in women.

Assessed whether women self-handicap with alcohol consumption prior to engaging in a social evaluation task, which may be more relevant to their self-esteem than the intellectual tasks used in past self-handicapping studies on substance use. 113 women (aged 19–32 yrs), who were evaluated as normal drinkers, performed either a solvable or an insolvable social judgment task and then received either success feedback or no feedback. Ss received access to alcoholic and nonalcoholic beverages while awaiting a retest. The study terminated before the retest. The self-handicapping hypothesis that noncontingent success would produce relatively greater alcohol consumption was not supported. Regardless of feedback, insolvable test Ss consumed more alcohol than did solvable test Ss. Findings suggest that the hypothesis may be limited as a general model of alcohol consumption in both sexes. (13 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-awareness-reducing effects of alcohol consumption.

Three experiments with 180 males examined the effects of alcohol consumption on the self-aware state. Based on a model proposed by J. G. Hull (see record 1982-05684-001), it was predicted that alcohol would reduce self-awareness. In Exp I, Ss consumed either alcohol or tonic and then gave short speeches about themselves. All Ss expected to consume alcohol. The speeches were coded for frequency of self-focused statements. In support of predictions, alcohol reduced the relative frequency of self-focused statements. Exp II replicated this finding and demonstrated that it did not depend on Ss' expectancies regarding the beverage they consumed. Exp III investigated a potential mechanism for these effects. Alcohol was proposed to reduce self-awareness by interfering with the encoding of self-relevant information. Using an incidental-memory paradigm, it was found that high-private self-conscious Ss recalled more self-relevant words than did low-self-conscious Ss under placebo conditions, thus replicating the findings of Hull and A. S. Levy (see record 1980-27166-001). (32 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Expectancies, alcohol, and sexual arousal in women.

A total of 40 university female volunteers, all social drinkers aged 18–35 yrs, were randomly assigned to 1 of 2 expectancy conditions in which they were led to believe that the beverage they were administered contained either vodka and tonic or tonic only. For half the Ss in each expectancy condition, the beverage actually contained vodka; for the other half, tonic only. After their drinks, measures of vaginal pressure pulse obtained with a vaginal photoplethysmograph were recorded during a nonerotic control film and 2 erotic films depicting a heterosexual or a homosexual interaction. The 2 groups that received alcohol, regardless of whether they believed that their drinks contained alcohol, showed significantly reduced sexual arousal during both erotic films. No effects of expectancy or an interaction between alcohol and expectancy were obtained. Ss' subjective estimates of intoxication were significantly correlated with their self-report of sexual arousal during both erotic films. The differences between these results and previous findings using similar procedures with male social drinkers are discussed.

Naltrexone's effects on reactivity to alcohol cues among alcoholic men.

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.

Self-consciousness, self-esteem, and success–failure as determinants of alcohol consumption in male social drinkers.

Tested the proposition that alcohol is consumed as a function of the quality of past performances and of the individual's level of private self-consciousness. 120 adult male Ss were randomly given success or failure feedback on an intellectual task. They then participated in a separate "wine-tasting" experiment in which they were allowed to regulate alcohol consumption. As predicted, high self-conscious Ss who had received failure feedback drank significantly more than did high self-conscious Ss who received success feedback. Consumption by low self-conscious Ss fell between these extremes and did not vary as a function of success and failure. Ss' scores on the Multiple Affect Adjective Check List indicated that these results were mediated by differential sensitivity to the positive or negative implications of success/failure by high and low self-conscious Ss.

Effects of alcohol on aggression in male social drinkers.

Assigned 96 male undergraduates to 1 of 8 groups in a 2 * 2 * 2 factorial design. To control fully for expectation effects, 48 Ss were led to believe that they would be drinking alcohol (vodka and tonic), and 48 believed they would be drinking only tonic water. Within each of these 2 groups, 24 Ss actually received alcohol, but 24 were given only tonic. Following the beverage administration, 48 Ss were provoked to aggress by exposing them to an insulting confederate, whereas control Ss experienced a neutral interaction. Aggression was assessed by the intensity and duration of shocks administered to the confederate on a modified version of A. H. Buss's aggression apparatus. The only significant determinant of aggression was the expectation factor: Ss who believed they had consumed alcohol were more aggressive than Ss who believed they had consumed a nonalcoholic beverage, regardless of the actual alcohol content of the drinks. Ss receiving alcohol, however, showed a significant increase in a reaction time measure, regardless of the expectation condition. Provocation to aggress was also a significant determinant of aggression, but it did not interact with the beverage conditions.

Cognitive theory and the generality of pessimism among depressed persons.

38 depressed (as measured by the Beck Depression Inventory) and 52 nondepressed college students were given a series of anagrams to solve. A 1-chance subgroup was informed that they would win a free movie ticket if they were successful in the task. A 2nd-chance subgroup received the same instructions as the 1-chance subgroup but were also informed that if they failed, they would have another opportunity in a different, undefined task. Ss were subdivided into success and failure subgroups that either succeeded at or failed the anagram task. Immediately afterwards, Ss reported their emotional state on the Multiple Affect Adjective Check List. Depressed Ss reported greater depression, anxiety, and hostility than nondepressed Ss in the 1-chance condition but not in the 2nd-chance condition; this interaction occurred independent of Ss' success or failure in the task. Results are viewed as indicating that current cognitive theories about the generality of pessimism in depression are incomplete. An explanation of the results in terms of the saliency of future reward opportunity is suggested as a basis for further study.

Replicated MMPI subtypes for alcoholic men and women: Relationship to self-reported drinking behaviors.

Derived replicated MMPI clusters for 188 inpatient alcoholic males (mean age 40 yrs) and 112 inpatient alcoholic females (mean age 41 yrs) and conducted subsequent MANOVAS with the resulting subtypes for men and women to evaluate differences on an alcohol-use inventory measuring Ss' alcohol expectancies, patterns of use, and drinking consequences. It is noted that shortcomings of previous cluster-analytic research include failure to replicate clusters across separate samples and lack of external measures against which to evaluate the predictive validity of cluster typologies. In the present study, the alcoholic male sample included 94 experimental and 94 replication Ss, while the female sample included 56 experimental and 56 replication Ss. The MMPI was administered to all 150 experimental Ss, and the same MMPI scale scores were obtained from replication Ss' hospital records. The alcohol-use inventory was administered to all 150 experimental Ss. MANOVA revealed significant differences among subtypes of alcoholic women, but relatively poor differentiation among subtypes of men by these measures. Among women, increasing psychopathology on the MMPI was predictive of increasing quantities of alcohol intake and other substance abuse, obsessive preoccupation with alcohol consumption, and affective and physiological disturbances related to drinking consequences.

Alcohol and stress response dampening: pharmacological effects, expectancy, and tension reduction

Alcohol consumption and alcohol expectation were separately evaluated in terms of effects on psychophysiological levels prior to stress and reduction of the magnitude of response to stress. 96 male, experienced drinkers were assigned to 8 conditions in a between-Ss design in which beverage consumed (alcohol or tonic), beverage expected (alcohol or tonic), and stressor (self-disclosing speech or threat of shock) were manipulated. Dosage for Ss receiving alcohol was 1 g ethanol/kg. Results indicate strong effects of alcohol consumption on prestress levels, consisting of accelerated heart rate (HR), lower HR variability, higher skin conductance, longer pulse transmission time (PTT), higher "cheerfulness" and lower "anxiety" ratings. Alcohol consumption significantly reduced the magnitude of the HR, PTT, and anxiety responses of Ss to the stressors. No effects attributable to alcohol expectation were found. Results are integrated with the existing literature concerned with pharmacological and cognitive effects of alcohol as they pertain to stress, psychophysiological responses to stress, and tension reduction.

Expectancy and pharmacological effects of alcohol on human cognitive and motor performance: The compensation for alcohol effect.

42 male undergraduate social drinkers were led to expect either alcohol or tonic. After actually consuming no alcohol, a low dosage, or a moderate dosage, they performed various cognitive and motor tasks. A questionnaire assessed Ss' responses to the expectancy manipulation and either preceded or followed task administration. A 2?×?3?×?2 MANOVA resulted in a significant Expectancy?×?Dosage interaction for cognitive tasks (letter cancellation, digit span, Raven Progressive Matrices). Ss apparently compensated for alcohol-induced deterioration on these tasks when they were aware they had consumed alcohol. No consistent effects were found for motor tasks (finger tapping, stylus monitoring, standing steadiness, and walking steadiness).

Alcohol cue reactivity, negative-mood reactivity, and relapse in treated alcoholic men.

Relapsed alcoholic individuals frequently report that negative emotional states trigger their return to drinking. A parametric laboratory study was conducted to assess the separate and combined effects of exposure to alcohol-related stimuli and induced negative moods in abstinent alcoholic persons. The authors also sought to determine if reactivity to alcohol cues or reactivity to negative mood induction predicted relapse soon after treatment. Men with alcoholism (N?=?50) undergoing inpatient treatment participated in a guided imagery procedure designed to induce negative moods and were then exposed to either their favorite alcoholic beverage or to spring water. Results indicated that both alcoholic beverage presentation and negative affect imagery led to increased subjective reporting of desire to drink. These effects were additive but not multiplicative (i.e., the interaction of mood state with beverage type was not significant). Reported urge to drink during the trial that combined negative mood imagery with alcoholic beverage exposure predicted time to relapse after inpatient discharge.

The structure of attitudes toward alcohol: Specific beverages differ from generic alcohol.

Examined the extent to which attitudes about alcohol in general differ from attitudes toward specific types of alcoholic beverages (e.g., beer, wine) and whether S variables such as drinking status and drink preference moderate alcohol-related attitudes. 82 male and 102 female college students completed a computerized attitude and drinking habits assessment. Ss did discriminate among alcoholic beverages on the dimensions of potency and positivity. Five of the 6 specific beverages were rated as less potent than generic alcohol (GA); mixed drinks were rated more positively than GA. Ss consistently rated their preferred beverage more positively than GA. Results suggest that the attitude structure characterizing specific alcoholic beverages differs from that of GA.

Effect of instructions and feedback on blood alcohol level discrimination training in nonalcoholic drinkers.

Investigated whether nonalcoholic drinkers can be trained to discriminate their blood alcohol levels (BAL) on the basis of internal cues. 72 male undergraduates classified as heavy drinkers came to the laboratory for 3 consecutive sessions, each consisting of 5 BAL estimation trials. The 2 manipulated independent variables factorially combined were beverage sequence and administration of BAL feedback. All Ss were told that they would receive mixed drinks containing vodka and tonic on each day, and all Ss received alcohol on Day 1. On Day 2, half of the Ss received alcohol and half received tonic alone; similarly, half of the Ss in each of these groups received either alcohol or tonic on Day 3. No S received BAL feedback on Day 1, and one-third of Ss did not receive feedback on Days 2 and 3. The remaining Ss received feedback on Day 2; half of the latter Ss also received feedback on Day 3, and half did not. Ss did not learn to discriminate their BAL on the basis of internal cues. Results are discussed in reference to the utility of BAL discrimination training in alcoholism prevention programs. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive changes after alcohol cue exposure.

A study was conducted to examine cognitive changes in alcoholics and nonalcoholics after alcohol cue exposure. Forty-nine alcoholics in treatment and 26 nonalcoholics recruited from the community were exposed to a neutral stimulus and to their favorite alcoholic beverage. They held and sniffed the beverage but were not allowed to consume it. Results indicated that both alcoholic and nonalcoholic subjects showed the following changes after alcohol cue exposure: increased desire to drink, increased expectations of pleasant alcohol effects, decreased expectations of arousal, and decreased expectations of behavioral impairment from drinking. Alcoholic subjects responded to alcohol cues with reports of increased physical symptoms, decreased confidence about coping with future temptation, and increased guilt. These results are consistent with Marlatt's hypothesis that an alcoholic in a high-risk relapse situation experiences an increase in positive outcome expectations and a decrease in self-efficacy. The results are also consistent with a respondent conditioning model of craving. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
