Although accumulating research indicates that negative expectations about interracial interactions undermine the quality of such interactions, little research has examined the factors that moderate the influence of negative expectations on responses to interracial interactions. We propose that individuals who endorse work-related ideologies such as the Protestant work ethic (PWE) expect that outcomes in interracial interactions should be contingent upon individual effort. As a result, such individuals are hypothesized to respond in a negative manner when they believe that regardless of their effort in an interracial interaction, interaction partners will respond negatively to them (termed negative response expectancies). Consistent with this hypothesis, negative response expectancies led to an increased desire to avoid interracial interactions (Studies 1a and 1b) and more antisocial behavior directed at an interracial interaction partner among individuals who strongly endorsed the PWE (Study 2). Across the studies, effects of negative response expectancies were relatively weaker or non-significant among individuals lower in the PWE. The implications of these findings for understanding the interplay between the PWE and expectancies in interracial interactions are discussed.

The present studies attempted to clarify the constructs of self-efficacy and outcome expectancies in relation to college student drinking. In study 1, heavy-drinking college students were asked for efficacy judgments for limiting their heavy-drinking for increasing periods of time (e.g. 1 day, 1 week, 1 month, etc.). Students were also asked for efficacy judgments for throwing a basketball into a hoop from increasing distances (e.g. 5 feet, 10 feet, 15 feet). Hypothetical incentives were offered to change efficacy ratings for the first tasks on each hierarchy (limiting drinking and basketball) to which the participant had responded with a negative efficacy judgments. Hypothetical incentives were also offered for the most difficult task on each hierarchy. As predicted, students changed efficacy ratings for limiting drinking much more frequently. Additionally, heavy-drinking college students indicated that money persuaded them to alter their efficacy judgments for limiting drinking, but lack of ability predominated as the reason for not altering basketball task efficacy. In study 2, the relationship between ability judgments, willingness, and outcome expectancies was explored by manipulating the wording of questionnaires presented to heavy-drinking college students. Results indicated that ability judgments were higher than willingness judgments for limiting drinking. Willingness appeared to be related to expected positive and negative effects of consuming alcohol. Principle components analysis indicated that ability and willingness were distinct constructs. Results of both studies are discussed in terms of the ongoing debate between Albert Bandura and Irving Kirsch and the need for a more clarity regarding efficacy and its measurement. / Master of Science

Self-efficacy for avoiding alcohol use predicts alcohol use after treatment. However, self-efficacy predicts outcome differentially depending on whether ratings are made before or after treatment. In order to increase the predictive validity of self-efficacy judgments, the hypothesized sources of self-efficacy were examined in the current study utilizing a college student population. Self-efficacy ratings for avoiding heavy drinking before and after self-monitoring of drinking behavior were examined in order to understand whether careful examination of current behavior would result in more informed self-efficacy judgments. Participants (N = 135) completed questionnaires that assessed self-efficacy, drinking behaviors, alcohol expectancies, and perceived normative alcohol use. Participants were assigned to either the control or self-monitoring condition. Self-monitors recorded drinking behaviors during the four weeks after the baseline assessment. All participants returned for a follow-up assessment four weeks later. Consistent with predictions based on social cognitive theory, heavy drinking, positive alcohol expectancies, and perceived norms of use were inversely related to self-efficacy. Hierarchical multiple regression analyses indicated that self-monitoring did not lead to stronger relationships between source variables and self-efficacy. Individuals who appeared to be overconfident in their self-efficacy judgments at baseline did not make more accurate ratings as a result of self-monitoring. Results from this study highlight potential sources of information individuals use in making self-efficacy judgments. / Master of Science

Understanding the etiological and maintaining processes of problematic drinking continues to be a challenge. There has been a growing amount of research focusing on the decisional processes that act to maintain addictive behaviors. Elucidating this underlying process is key to understanding the range of drinking behavior observed among individuals. Rather than relying on one theory, examining overlap between multiple theories of alcohol use may lead to a better understanding of such a process. Using a construct validation approach, this study utilized motivational (Ambivalence Model of Craving), cognitive (Alcohol Outcome Expectancy Theory), and behavioral theories (Behavioral Economics) of alcohol use to examine the extent to which they tap into a common underlying decisional process of alcohol use behaviors. Two methods were used including establishing motivational profiles using latent profile analysis and an experimental manipulation of situational context to examine the effect of setting on constructs of interest. Results from the two studies provided partial support for the overlap between these theories as it pertains to a common underlying process.

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 main goal of this study is to examine the relationship between weight control expectancies, weight concerns, smoking rate and perceived likelihood of smoking in the future among Spanish adolescents. Specifically, I intend to explore the potential moderator role of weight concerns on the relationship between weight control expectancies and smoking rate, as well as between weight concern and perceived likelihood of smoking in the future. Additionally, I want to investigate the possible meditational role of weight control expectancies on the relationship between weight concerns and smoking rate and likelihood of smoking in the future, respectively. The participants were 311 Spanish adolescents (M = 15.20; SD = 1.63; 174 female and 137 male) from schools in Alicante, Spain. The students completed questionnaires regarding smoking history and status. They also responded to questions regarding smoking expectancies and weigh concerns. Results suggested differences between smokers and nonsmokers in weight control expectancies and fear of fatness regardless of gender. The moderator model of weight concerns was not supported by findings. The results prove the meditational role of weight control expectancies on the relationship between fear of fatness and smoking rate, as well as between fear of fatness and perceived likelihood of smoking in the future. Implications, directions for future research and limitations of the study are discussed.

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

The present study investigated how knowledge of tonality is used in sight-reading by comparing sight-reading accuracy across three tonal constructs: major, minor and atonal. It was hypothesized that sight-reading performance would be the worst in instances with no tonal information, as participants would be unable to generate appropriate top-down expectancies to guide their sight-reading. To test this, twelve pianists sight-read major, minor and atonal versions of monophonic, homophonic and polyphonic excerpts. The results indicated that pianists performed the major excerpts with greater accuracy than the atonal excerpts. Furthermore, the errors made within the major excerpts were significantly biased towards diatonicism, and there was a global shift towards tonality in participants’ atonal performances, providing a clear demonstration of how pianists’ expectations might have contributed to their sight-reading performance. The diatonic bias was not found in the minor excerpts, suggesting that the minor hierarchy does exert as strong of an influence during sight-reading.
