A recent line of research grounded in evolutionary theory has shown that exposure to women's fertility cues affects men's mating cognition and behavior. This area of research has not yet been examined in relation to alcohol. As alcohol has also been shown to facilitate the formation of sexual connections for males, establishing the intersection between these two lines of research seems necessary to understand the impetus behind human behavior. Ninety-eight male participants were primed with either the scent of a fertile woman or the scent of nonfertile woman and then completed measures assessing their level of attraction to pictures of women, beer consumption, approach behavior, and alcohol expectancies. Results of the study indicated that males' mating behaviors are affected by women's ovulatory cues, as men exposed to an ovulation prime drank significantly more and exhibited significantly more approach behavior than men exposed to a control prime. Furthermore, an interaction was found between sexual enhancement expectancies and prime condition on beer consumption, which indicated that there was no effect for sexual enhancement expectancies for those in the control prime condition, but for those in the ovulation prime condition, increased drinking was associated with higher sexual facilitation expectancies. These findings were consistent with previous research and support evolutionary theories of mating behavior while taking an integrative approach in trying to explain factors behind human behavior.

The current study investigated the cognitive organization of alcohol expectancies using event-related potentials (ERPs). Building on previous behavioral and ERP paradigms, the goal of the current study was to quantify the relationship among alcohol expectancies using ERP indices of salience, congruence, and cognitive distance. The ERP components being evaluated fit perfectly into the alcohol expectancy theory and research; however, implementing specific paradigms to reliably measure individual differences in alcohol expectancies using ERPs has proven to be more elusive than originally thought. This study utilized established cognitive modeling techniques coupled with ERP responses to linguistic stimuli. In essence, this study provides an implicit measure of how particular types of words, in the context of alcohol, are categorized and integrated into individuals' expectancy frameworks. The study looked at two specific ERP components, the P300 and the N400, that have been shown to be sensitive to expectancy violations. In a sentence processing task the P300 was predicted to be related to individuals' alcohol expectancies and in a word pair task the N400 was predicted to index these expectancies. Results indicated that the P300 and N400 were both related to alcohol expectancies in the sentence task and the N400 was related to alcohol expectancies in the word pair task. While the results supported parts of the hypotheses, they were not unequivocal endorsements of the hypothesized relationships, perhaps highlighting the countervailing forces of salience and expectancy congruence. Furthermore, there were unexpected differences between males and females in the sample that interacted with the effect of expectancy on ERPs. In sum, prior research has highlighted individuals' expectations about alcohol as a mediator of biopsychosocial risk for alcohol use disorders (Goldman, 2002), and the results of this study provide a model for how ERP measures of expectancy could capture an aspect of individuals' risk based on reactions to expectancy related stimuli

Altering alcohol expectancies has reduced alcohol use among college students and may lead to successful prevention of alcohol use among high school students. We randomly assigned 379 12th-grade students to an expectancy challenge, traditional alcohol information, or control condition, and used Individual Differences Scaling to map expectancies into memory network format with Preference Mapping to model likely paths of association. After expectancy and traditional alcohol interventions, higher drinking male participants exhibited a greater likelihood to associate alcohol use with negative and sedating consequences and a decreased likelihood to associate alcohol with positive and arousing consequences. Drinking decreases paralleled the magnitude of changes in their likely path of expectancy activation. Children and adults who emphasize negative and sedating effects have been found to be less likely to use alcohol. Therefore, expectancy challenge interventions that have been successful at modifying expectancies and subsequently decreasing alcohol consumption among heavy drinking college students may be useful in the development of prevention curricula for high school students.

Alcohol use has been a longstanding problem on college campuses. Despite the efforts National Institute on Alcohol Abuse and Alcoholism and the commissioned Task Force on College Drinking (2002), there has been a recent rise in the number of alcohol related arrests and violations on college campuses. Within the high-risk mandated student population, the most successful programs utilize motivational enhancement strategies, such as the Brief Alcohol Screening and Intervention for College Students (BASICS). Likely due to financial constraints, an important issue that has been raised is the limited availability of validated methods for alcohol prevention and intervention on college campuses. The purpose of this study was to examine the effectiveness of the digitally assisted Expectancy Challenge Alcohol Literacy Curriculum (ECALC) by direct comparison of the ECALC to an already well-established treatment (i.e., BASICS) in an effort to reduce problematic alcohol use and related negative consequences among mandated college students. The role of the digital enhancements is to decrease time and resources necessary for training facilitators and aid in widespread implementation. Analyses revealed significant reductions on all four positive alcohol expectancies subscales for those in the ECALC condition and a significant intervening effect for the expectancies of Sociability and Liquid Courage. Results also revealed that for both males and females, those in the ECALC condition demonstrated significantly greater reductions in frequency of alcohol use (i.e., number of drinking days per month) and comparable reductions in typical (i.e., mean BAC, average drinks per sitting, average drinks per week) and heavy alcohol use (i.e., peak BAC, peak drinks per sitting, number of binge episodes) at follow-up when compared to those in the BASICS condition.

Social anxiety is widely thought to be positively associated with alcohol use. However, these studies rely primarily on self-report of drinking behavior. This research aimed to further explore this research by assessing blood alcohol concentration (BAC), a physiological measure of alcohol intoxication, as the dependent measure in naturalistic settings (i.e., fraternity parties). Results from Study 1 suggest a weak relationship between self-reported anxiety levels and BAC. Study 2 was based on Burke and Stephen's (1999) proposed social cognitive model in which alcohol expectancies and drink-refusal self-efficacy act as moderators of the relationship between dispositional social anxiety and alcohol consumption. Analyses (n=86) did not support a relationship between social anxiety and alcohol use, nor the moderating effects of alcohol expectancies and drink-refusal self-efficacy. Implications for this type of research and possible future directions are discussed. / Master of Science

Research on self-control suggests that people do not do as well at self-control after they have already exerted self-control on something else. Despite the obvious importance of self-control in drinking behavior, few studies have examined alcohol consumption as an outcome measure in the context of self-control depletion and the potential role of cognitive processes in the self-control to drinking relationship remains largely unexplored. Although it is widely agreed that alcohol expectancies play an important role in one's decision to drink, no study has examined the role of expectancies in self-control's influence on drinking. This study addresses this important gap in the research by testing whether positive expectancies for alcohol influence the relationship between self-control depletion and placebo alcohol consumption in the laboratory. Results offer support for the resource model of self-control depletion in the context of drinking decisions; participants in the depleted self-control condition drank more placebo alcohol despite being reminded to be ready for an upcoming memory task. Hypotheses of conditional and indirect effects consistent with a process model of self-control were not supported. Using nonparametric analytic techniques, patterns in the data emerged suggestive of conditional indirect effects, though they appear to be very small in scale. Findings support the further exploration of the primary hypotheses, given the consideration of current limitations.

This study examined the independent and interactive effects of acute alcohol consumption, perceived alcohol consumption of a female confederate, and distal alcohol expectancies of intoxicated women, on sexual aggression. Participants were a diverse community sample (54% African-American) of heterosexual males (N = 156) between 21 and 35 years of age who were recruited to complete the study with a male friend and an ostensibly single, heterosexual female who reported a strong dislike of sexual content in the media. Sexual aggression was measured utilizing a well-validated laboratory paradigm in which participants viewed a sexually explicit or non-sexually explicit video clip as part of a contrived media rating task and made individual choices of which video clip to show the female confederate. Sexual aggression was operationalized as selection of the sexually explicit video, as opposed to the non-sexually explicit video. Results demonstrated that acute alcohol consumption, perceived female alcohol consumption, and distal alcohol expectancies of women’s vulnerability to sexual coercion and sexual drive while intoxicated, were not significantly related to sexual aggression utilizing the current paradigm. Post-hoc analyses revealed that the primary predictor variables were significantly related to participants’ perceived distress of a female confederate following an act of sexual aggression. Discussion focused on understanding what factors may have been relevant in understanding why the primary predictor variables were not significantly related to sexual aggression utilizing the current paradigm. Finally, clinical implications were explored in addressing a lack of perceived distress in potential female victims by individuals who endorsed higher levels of distal alcohol expectancies of intoxicated women’s vulnerability to sexual coercion and what potential interventions be utilized clinically.

Investigations of the anticipated effects of alcohol indicate that cognitive frameworks are highly correlated with drinking and other variables associated with alcohol use, explaining up to 50% of the variance in drinking outcomes (Goldman, Darkes, & Del Boca, 1999; Goldman, 2002; Goldman et al., 2006; Goldman, Reich, & Darkes, 2006). Furthermore, alcohol expectancies appear to mediate the relationship between a variety of risk factors, such as sensation seeking, and alcohol outcomes (Darkes, Greenbaum, & Goldman, 2004). The current study examined the relationship of these cognitive networks with a physiological index of expectancy violation Participants were presented with statements reflecting a wide range of alcohol outcome effects, which either violated or confirmed the participant’s own set of alcohol expectancies, while the ERPs evoked by these stimuli were recorded. As predicted, the P300 amplitude elicited by negative alcohol expectancy stimuli was positively correlated with the degree of endorsement of positive/arousing expectancies on the self-report measure. That is, the higher the individual’s positive/arousing expectancies, the larger the P300 elicited by stimuli asserting the negative effects of alcohol. There was no significant correlation, however, between P300 amplitude elicited by positive alcohol expectancy stimuli and the degree of endorsement of negative/sedating expectancies on the selfreport measure. In addition, individual differences relating to alcohol expectancies were examined as well. These results were able to identify specific stimuli that violated expectancies for each individual, as well as those that tended to violate expectancies in systematic ways across subjects. These findings provide a way forward for more precise assessment and prediction based on the well developed cognitive model of Alcohol Expectancies. In sum, variations in the amplitude of the P300 were consistent with the model of Alcohol Expectancies. Words imputing negative/sedating effects of alcohol elicited a large P300 in individuals with higher positive alcohol expectancies. By indexing the brain’s electrophysiological response sensitive to expectancy violations, these findings demonstrate concordance between verbal measures of alcohol expectancies, which by their very nature are introspective, and a psychophysiological index of expectancy thought to operate automatically and to be independent of overt responding.
