Women's sexual arousal: Effects of high alcohol dosages and self-control instructions

The basic relationship between alcohol and women's sexual arousal – especially genital arousal – received little research attention for nearly 30 years (e.g. Wilson and Lawson, 1978) until very recently (e.g. George et al., 2009). To investigate hypotheses based on earlier findings and Alcohol Myopia Theory (AMT), two experiments evaluated the effects of high blood alcohol concentrations (BACs) and arousal instructional demands on indices of vaginal responding and self-reported sexual arousal. In Experiment 1, self-control instructions to maximize (versus suppress) arousal increased peak and average Vaginal Pulse Amplitude (VPA) change. Self-control also interacted with a target BAC of .08% (versus .00%) to influence latency to peak arousal onset: Intoxicated women instructed to maximize showed a shorter latency to peak arousal than did intoxicated women instructed to suppress; however, sober women showed an undifferentiated pattern. Also, in Experiment 1, the target BAC of .08% had no effect on VPA or subjective arousal measures. In Experiment 2, a target BAC of .10% (versus .00%) attenuated peak change and average change in VPA, but this dosage had no effects on latency to peak achieved arousal, or on subjective arousal. Instructions to maximize arousal (versus no instruction) had no effect on any arousal measures. Overall, among young moderate drinking women, alcohol had attenuating effects but only at the higher dosage. Maximize versus suppress instructions about arousal had predicted effects on arousal and interactive effects on latency, but only at the lower dosage. The findings highlight the importance of dosage and contextual factors in alcohol's impact on the variability of women's sexual responding.

Triggers for alcohol‐related violence in young male offenders

Purpose. Improving the effectiveness of offender treatment programmes is important and one approach is to attend to their content. The aim here was to identify triggers to alcohol‐related violence to inform the development of programmes to treat this problem.Method. Information from 149 young male offenders’ accounts of incidents of alcohol‐related violence was studied using thematic analysis.Results. Sixteen triggers for violence were identified and these were organized into six themes: (1) being offended by someone, (2) seeing an opportunity for material gain, (3) seeing others in need of help, (4) perception of threat, (5) distress, and (6) wanting a fight.Discussion. The implications of the results for developing treatments for alcohol‐related violence are presented. First, identifying triggers should be part of the treatment programme and ways of avoiding triggers should be addressed. Second, changing values, specifically hypermasculine and antisocial values, could attenuate the rewards signalled by the triggers. Third, methods of reducing the potency of triggers would be of value and would include addressing issues of need for respect and responses to perceived disrespect. Fourth, non‐violent ways of helping people who are in trouble need to be introduced. Fifth, coping with threat cues through distraction and increasing self‐awareness would reduce the effects of ‘alcohol myopia’. Sixth, seeking fights for excitement could be reduced by examining the costs through motivational procedures. Finally, and self‐evidently, a primary target of treatment programmes to reduce alcohol‐related violence should be to reduce the level and frequency of alcohol intoxication.

P01-86 - Acute effects of alcohol in sexual behavior

The belief that alcohol can lead to sexual risk and/or sexual inadequate behaviors is nearly ubiquitous. But can we talk about causality? Several studies, with different methodology, have been developed during the last decades in an effort to understand the relationship between alcohol and sexual behaviors and function. From the knowledge that we already have, it is worth it to highlight alcohol consumption effects on cognitive appraisals, based on Response Conflict Model or Alcohol Myopia Model, as well as the expectancies effect. Future research is essential, specially to overcome the failures and limitations of the previous studies.

The Effects of Acute Ethanol Consumption on Sexual Response and Sexual Risk-Taking Intent

Two theories of sexual risk taking (disinhibition and alcohol myopia) were tested using genital measures of sexual response and computer measures of sexual risk propensity. A total of 44 men and women completed two sessions comparing responses to erotic films while consuming alcohol (breath alcohol doses were .025g/kg and .08g/kg) or juice alone. After consuming alcohol, more sexual arousal was reported in response to neutral films and at a breath alcohol level of .08g/kg as compared to no alcohol. Genital responses for men and women increased during sexual films, but men did not respond as strongly when breath alcohol level was .08g/kg. Intentions to have intercourse with a new partner at baseline predicted the level of sexual arousal reported. As self-reported sexual arousal increased in response to sexual films and higher alcohol dose, the intent to engage in intercourse with a new partner increased. Alcohol dose was not related to later sexual intercourse intentions. With no direct relationship of alcohol and intercourse intentions, results appear more consistent with a disinhibition model of sexual arousal.

Alcohol intoxication and memory for events: A snapshot of alcohol myopia in a real-world drinking scenario

Alcohol typically has a detrimental impact on memory across a variety of encoding and retrieval conditions (e.g., Mintzer, 2007; Ray & Bates, 2006). No research has addressed alcohol's effect on memory for lengthy and interactive events and little has tested alcohol's effect on free recall. In this study 94 participants were randomly assigned to alcohol, placebo, or control groups and consumed drinks in a bar-lab setting while interacting with a “bartender”. Immediately afterwards all participants freely recalled the bar interaction. Consistent with alcohol myopia theory, intoxicated participants only differed from placebo and control groups when recalling peripheral information. Expanding on the original hypervigilance hypothesis, placebo participants showed more conservative reporting behaviour than the alcohol or control groups by providing more uncertain and “don't know” responses. Thus, alcohol intoxication had confined effects on memory for events, supporting and extending current theories.

Alcohol, emotion and attention: revisiting the Alcohol Myopia Theory

Among the known effects of alcohol on behavior, the modulation of cognitive functions (such as attention and memory), emotion, risk-taking and aggressive behavior are noteworthy. Here, we performed literature review in order to reinterpret alcohol effects on behavior according to the Alcohol Myopia Theory. According to this construct, there is a reduction of attentional resources during alcohol intoxication, which are primarily allocated to the most salient events in a given situation. The consequence is a hyperfocus directed to emotional situations when they are sufficiently relevant to grab attention, or a reduced attentional focus to emotional events in the presence of a relevant demanding task. The understanding of the mechanism mentioned above support the discussion of propositions toward the prevention of problems related to alcohol consumption. Importantly, the attentional allocation model provides inputs for a discussion on the scientifically-supported public health propositions aimed at preventing problems related to acute alcohol intoxication.

Alcohol intoxication and self-reported risky sexual behaviour intentions with highly attractive strangers in naturalistic settings

Objective: The present investigation examined the relationship between alcohol intoxication and risky sex intentions in naturalistic settings.Methods: Heterosexual young adults (n = 72) were approached at a campus pub and at campus parties. Blood alcohol concentration (BAC) was measured by a breath test and ranged from 0 to 0.18%. Participants rated their likely intent to have sex with 10 highly attractive unfamiliar models of the opposite gender, as depicted in photographs, if the opportunity arose. Photos varied in terms of accompanying information regarding risk, with three levels: slight risk, moderate risk and high risk.Results: BAC was significantly positively correlated with self-reported likelihood of young adult men engaging in risky sex with highly attractive unfamiliar models at all risk levels, whereas in young adult women the relationship was significant only at the slight risk level. Men reported significantly higher intent to have risky sex than women did at all risk levels.Conclusions: Results are discussed in terms of the framework of alcohol myopia theory as well as alternative interpretations.

Use of drinking protective behavioral strategies in association to sex-related alcohol negative consequences: The mediating role of alcohol consumption.

Alcohol use has been implicated as a risk factor for sexual negative consequences, such as unprotected sexual intercourse. The present research was conducted to examine the relationship between drinking protective behavioral strategies and consensual sex-related alcohol negative consequences, and whether this relationship varied by gender. Additionally, typical number of drinks during sexual behavior was evaluated as a potential mediator of this association. Heavy drinking, sexually active college students (N = 297, 50.2% women) completed self-report measures of drinking protective behavioral strategies, alcohol consumption, and sex-related alcohol negative consequences. Findings indicated that women who used drinking protective behavioral strategies more frequently were less likely to experience sex-related alcohol negative consequences whereas this relationship was not significant for men. For women, this relationship was mediated by the typical number of drinks consumed during sexual behavior. The current research demonstrates that use of drinking protective behavioral strategies is related to a reduction in women's sex-related risks when drinking. Findings are discussed in terms of alcohol myopia theory. Implications for interventions aimed to reduce higher risk sexual behavior among college students are discussed.

Alcohol Use and High-Risk Sexual Behavior Among Collegiate Women: A Review of Research on Alcohol Myopia Theory

A review of current English literature in the areas of high-risk alcohol use and sexual behavior was conducted from September 2007 to December 2008. Objective: The purpose was to specifically review studies that used alcohol myopia theory (AMT) as the theoretical perspective from which they were evaluated and analyzed. Participants: Collegiate women were the population of interest in the review. Methods: Literature was acquired through searches within the Academic Search Premier and PubMed databases using the keywords “college,” “women,” “risk,” “alcohol,” “sex,” and “alcohol myopia.” Results: Results articulate the high prevalence of negative sexual consequences related to alcohol use among college-aged women and the utility of AMT. Conclusions: Future interventions aimed at decreasing high-risk alcohol and sexual behaviors among college women should incorporate AMT. Continued theory-based research examining the relationship between alcohol use and sexual behavior is needed to inform future interventions and better understand why college women continue to consume high levels of alcohol and engage in risky sexual behaviors despite the threat of negative consequences.

Influence of heavy episodic drinking on the relation between men's locus of control and aggression toward intimate partners.

This study examined the interactive effects of locus of control and heavy episodic drinking on men's physical assault and sexual coercion against intimate partners. Participants were 151 heterosexual drinking men who completed self-report measures of locus of control, alcohol consumption during the past 12 months, and intimate-partner aggression during the past 12 months. An internal locus of control was associated with a lower frequency of physical assault and sexual coercion toward intimate partners among men who reported lower quantities of alcohol consumption. However, data suggested that the protective qualities of an internal locus of control for both forms of partner aggression diminished among men who reported higher quantities of alcohol consumption. These results support alcohol myopia theory and extend this theory by suggesting how alcohol consumption may affect the relation between locus of control and different forms of intimate-partner aggression toward women.

Are alcohol expectancies associations? Comment on Moss and Albery (2009).

Moss and Albery presented a dual-process model of the alcohol-behavior link, integrating alcohol expectancy and alcohol myopia theory. Their integrative theory rests on a number of assumptions including, first, that alcohol expectancies are associations that can be activated automatically by an alcohol-relevant context, and second, that alcohol selectively reduces propositional reasoning. As a result, behavior comes under the control of associative processes after alcohol consumption. We agree with the second but not with the first assumption, based on theoretical and empirical arguments. Although in some cases expectancies may involve a simple association, they are propositional in nature. We demonstrate that this assertion is supported by existing literature cited in Moss and Albery. Moreover, 6 recent studies consistently demonstrated that under circumstances in which executive control is impaired (either as a stable individual difference or under the acute influence of alcohol), associative processes, over and above expectancies, predict alcohol-related behavior. Taken together, the evidence strongly suggests a fundamental distinction between expectancies and associations in memory: Effects of propositional expectancies and executive functions are impaired under the acute influence of alcohol, but memory associations are not. This difference in perspective not only has theoretical implications but also leads to different predictions regarding acute alcohol effects in society.

An Experimental Investigation of the Interactive Effects of Alcohol and Sexual Arousal on Intentions to Have Unprotected Sex

We manipulated both alcohol intoxication and sexual arousal and presented male participants (N = 79) with a video vignette in which two undergraduates decide whether to have unprotected sexual intercourse. Participants were asked what they would do if they were in a similar situation, and we found that among sober participants, those assigned to a sexually arousing or neutral condition did not differ in their intentions to engage in unprotected sexual intercourse. Among intoxicated participants (M blood alcohol level = 0.08%), however, those assigned to the sexually arousing condition reported that they were more likely to have unprotected sex than did those assigned to the neutral cue condition. These findings support alcohol myopia theory (Steele & Josephs, 1990) and are consistent with prior nonexperimental work (MacDonald, MacDonald, Zanna, & Fong, 2000). Through the use of an experimental design, this study makes a new contribution by demonstrating that sexual arousal and alcohol intoxication interact to exert a causal influence on intentions to engage in risky sexual behavior.

The effects of alcohol and cue salience on young men's acceptance of sexual aggression

Research suggests that alcohol intoxication may increase a young man's likelihood of sexual aggression. This laboratory analogue experiment tested a disinhibition versus alcohol myopia explanation of alcohol's role by investigating effects of acute alcohol administration, expectations and individual differences drawn from Malamuth's Confluence Model of Sexual Aggression (i.e., Acceptance of Interpersonal Violence: AIV, Need for Sexual Dominance: NSD) on young men's acceptance of sexual aggression. Young adult heterosexual men ( n = 334) attended two laboratory sessions each. In the first, they completed screening and individual differences measures. In the second, they were assigned randomly to consume one of four beverages: Control, Placebo, Low Dose Alcohol (0.33 ml alcohol/kg body weight) or Moderate Dose Alcohol (0.75 ml/kg) and view one of two video-delivered scenario conditions: “Anti-Force Cues” (scenario of a couple on a date with embedded explicit cues mitigating against forced sex) or “No Cues” (Identical scenario with no Anti-Force cues). Participants then judged 1) should the man continue to force the woman to have sex? 2) would they force the woman? and 3) who was responsible for the outcome? Results supported a disinhibition versus alcohol myopia model. Consuming alcohol increased acceptance of sexual aggression. Further, higher NSD and AIV scores were associated with acceptance of forced sex, but only after alcohol consumption. Overall, findings showed that key individual difference factors from Malamuth's Confluence Model enhance precision of predicting sexual aggression risk by young men under the influence of alcohol.

Indirect Effects of Acute Alcohol Intoxication on Sexual Risk-taking: The Roles of Subjective and Physiological Sexual Arousal

Three experiments supported the idea that alcohol fosters sexual risk-taking in men and women, in part, through its effects on sexual arousal. In Experiment 1, increasing alcohol dosage (target blood alcohol levels of .00, .04, .08%) heightened men's and women's risk-taking intentions. Alcohol's effect was indirect via increased subjective sexual arousal; also, men exhibited greater risk-taking than women. In Experiment 2, an extended dosage range (target blood alcohol levels of .00, .06, .08, .10%) heightened men's risk-taking intentions. Alcohol's effect again was indirect via subjective arousal. Physiological sexual arousal, which was unaffected by alcohol, increased risk-taking via increased subjective arousal. In Experiment 3, alcohol increased women's risk-taking indirectly via subjective arousal, but alcohol-attenuated physiological arousal had no effect on risk-taking. Implications for alcohol myopia theory and prevention interventions are discussed.

T12-O-08 Alcohol and sexual risk taking in young heterosexual men: an empirical test of Alcohol Myopia Theory

Objective Sexual risk taking by heterosexual men is important to the high levels of sexually transmitted infections (STIs) and unplanned pregnancies. Alcohol Myopia Theory suggests that behaviour is influenced by an interaction between alcohol-induced cognitive impairment and environmental cues, thus reducing one's ability to process inhibitory cues. The present study addressed the intentions and justifications to engage in risky sexual behaviour according to level of intoxication and in conditions of both explicit and implicit inibitory conflict. Design and method 48 men were recruited in nightclubs for an interview. We employed a vignette methodology in order to create explicit or implicit inibitory conflict condition. Levels of blood alcohol concentration were measured and. Results When inibitory cues are not explicit, intoxicated subjects report greater intention to have an unprotected sexual intercourse, while there are no significant differences between sober and intoxicated subjects in justifications for risky behaviour. Conclusions These results therefore confirm the assumptions of alcohol myopia theory, showing that stronger environmental cues have much more influence on behaviour when cognitive and perceptive processes are impaired.

Alcohol's Effects on Sexual Decision Making: An Integration of Alcohol Myopia and Individual Differences

We conducted an experiment to test the applicability of integrating individual perceptions of unprotected sex consequences with alcohol's myopic effects as an explanatory framework for risky sexual decision making in young heterosexual men and women. Male and female participants (N = 61) rated their perceptions of unprotected sex consequences, received alcoholic (target breath alcohol concentration = .10%) or nonalcoholic drinks, and completed a risky sexual decision-making task that included a quantitative measure of sexual decision-making cue attention. Intoxicated participants were more attentive to impelling cues and reported greater sexual risk intentions than sober participants. Mediational analyses indicated that attention to cues fully mediated the alcohol-sexual risk intention relationship. Moderational analyses revealed that alcohol's focusing effect acts in conjunction with pre-existing individual perceptions to influence cue salience directly and sexual risk intentions indirectly. Findings demonstrate the importance of examining predispositional tendencies when investigating alcohol myopia as a mediating mechanism underlying the alcohol-risky sex relationship.

Preventing suicide in adolescents with alcohol use disorders

Adolescent suicide is an escalating crisis that needs to be addressed by clinicians and researchers. Alcohol use has consistently been implicated in adolescent suicide and it is generally assumed that alcohol use leads to an increased risk in suicidality, suicide attempts and completed suicides. It can lead to adolescent suicidality through alcohol myopia, disinhibition, and impaired judgment. Multiple genetically related intermediate phenotypes might contribute to the risk of alcohol misuse and suicidal behavior in adolescents. Genetic variations that enhance the risk for mood and anxiety symptoms or susceptibility to stress might increase risk through different mechanisms. Comorbid disorders such as depression are frequently exhibited in adolescents who misuse alcohol, therefore any adolescent who appears to be at risk for alcoholism or depression should always be screened for all other psychiatric disorders and for suicidality; some signs suicidal adolescents may exhibit include withdrawal, personality change, and a loss of interest in pleasurable activities. While assessment is important, prevention is crucial in any attempt to decrease the incidence of adolescent suicide. The US Center for Disease Control and Prevention (CDC) has established a set of seven guidelines that can be implemented from kindergarten through high school in order to establish alcohol prevention efforts in schools. Through beginning prevention efforts at a young age, it is hopeful that both alcohol misuse and adolescent suicide can be reduced.

The Role of Women's Alcohol Consumption in Managing Sexual Intimacy and Sexual Safety Motives

Two studies, based on an alcohol myopia model, were designed to understand the role of women's alcohol consumption on vulnerability to sexual assault. We predicted that, in a high- conflict social situation, alcohol would make it more difficult to recognize sexual assault risk, lowering intentions to resist sexual advances. In Study 1, women (N = 51) were recruited in bars and classified as having a high (.06 or greater) breath alcohol concentration (BrAC) or low BrAC. They were asked to project themselves into a hypothetical scenario that portrayed interest in establishing an intimate relationship and included mild sexual aggression. In Study 2, women (N = 101) were randomly assigned to an alcohol (target BrAC: .08%), placebo, or no-alcohol condition. They responded at two time points to a similar hypothetical scenario that described mild sexual aggression (Time 1) and serious sexual aggression (Time 2). In Study 1, women with higher BrAC perceived less risk in the scenario and anticipated less resistance than women with low BrAC. In Study 2, similar results were found but only following serious aggression. There were no placebo effects. Both studies suggest that the effects of alcohol on resistance are partially mediated via risk perceptions. Alcohol appears to reduce intentions to resist sexual advances from an acquaintance while increasing intentions to pursue relationship-enhancing behaviors. Effects are not completely explained by an alcohol myopia perspective. Differences in findings between the two studies may reflect differences in methodology, context, or sample.

“Groupdrink”? The Effect of Alcohol on Risk Attraction Among Groups Versus Individuals

The objective of the present study is to assess the impact of alcohol consumption on the risk orientation of people when they are in groups as opposed to alone. Alcohol is often consumed within social groups, but previous research has not distinguished whether particular group processes affect risk differently as a consequence of alcohol consumption. Three theory-based predictions are tested to see whether, after alcohol consumption, groups encourage or inhibit risk as a result of group polarization, deindividuation, or group monitoring. Male participants (N=120; ages 18-28), recruited via opportunity sample from students at the University of Kent, were assigned as individuals or as members of four-person groups. They had their breath alcohol concentration analyzed to ensure they were alcohol free and then were asked to consume either a placebo or alcohol in amounts equivalent to the legal limit for driving in the United States and the United Kingdom (.08% blood alcohol concentration). Participants completed a risk-attraction task either alone or in a group. Each participant also completed an alcohol-expectancy questionnaire. Individuals found risky choices significantly more attractive after consuming alcohol. In contrast, members of groups showed no such increase. In alcohol but not placebo conditions, groups made their decisions more slowly than did individuals. The results are consistent with the group-monitoring hypothesis (i.e., that group members attend to each other and promote a greater level of systematic processing of the risks presented). Results indicate that with moderate social drinking, groups may provide an informal means of mutual regulation and monitoring that can offset some aspects of alcohol myopia.

Alcohol-induced impulsivity in rats: an effect of cue salience?

There is a common assumption that alcohol produces impulsive behaviors, thereby increasing the preference for immediate over delayed rewards. An alternative explanation, provided by alcohol myopia theory, is that alcohol alters attentional processes such that intoxicated individuals respond exclusively to the most salient cues in their environment. We tested these two hypotheses in rats using standard (impulsivity) and modified (cue salience) versions of the delayed reinforcement task. In the impulsivity paradigm, rats were trained to choose between a small immediate reward (2 sucrose pellets) and a large delayed reward (12 sucrose pellets after 10 s) in a T-maze. In the cue salience paradigm, a light in one arm predicted either the small or the large reward, but the arm paired with the light varied across trials. In separate experiments, we examined how changes in delay to the large reward, alcohol administration, or alcohol combined with either a serotonin agonist [para-chloroamphetamine (pCA) at doses of 0.1, 0.4, 0.7, and 1.0 mg/kg, s.c.)] or a dopamine antagonist [cis-(Z)-flupenthixol dihydrochloride (alpha-flupenthixol) at doses of 0.0125, 0.025, 0.05, and 0.1 mg/kg, i.p.] affected performance in each task. Increasing the delay to the large reward increased impulsivity in both paradigms, but it had no effect on responding to a salient cue. Alcohol (0.6, 0.9, 1.2, and 1.8 g/kg, i.p.) increased the choice of the immediate reward and increased the choice of the lit arm, regardless of whether it signaled the small or the large reward. pCA selectively reduced alcohol-induced impulsivity, whereas alpha-flupenthixol selectively reduced responding to a salient cue. Rats, like humans, are influenced by cue salience when intoxicated. Although this alcohol myopia effect could explain alcohol-induced impulsivity, the two processes are probably distinct because they are mediated by dissociable pharmacological mechanisms.
