ABSTRACT This thesis proposes that a focus on the bodily level of analysis can unify explanation of behavior in cognitive, social, and cultural psychology. To examine this unifying proposal, a sensorimotor mechanism with reliable explanatory power in cognitive and social psychology was used to predict a novel pattern of behavior in cultural context, and these predictions were examined in three experiments. Specifically, the finding that people judge objects that require more motor effort to interact with as farther in visual space was adapted to predict that people with interdependent self-construal(SC) , relative to those with independent SC, would visually perceive their cultural outgroups as farther relative to their cultural in-groups. Justifying this cultural extension of what is primarily a cognitive mechanism is the assumption that, unlike independents, Interdependents interact almost exclusively with in-group members, and hence there sensorimotor system is less tuned to cross-cultural interactions. Thus, interdependents, more so than independents, expect looming cross-cultural interactions to be effortful, which may inflate their judgment of distance to the out-groups. Two experiments confirmed these predictions: a) interdependent Americans, compared to independent Americans, perceived American confederates (in-group) as visually closer; b) interdependent Arabs, compared to independent Arabs, perceived Arab confederates (in-group) as closer; and c) interdependent Americans, relative to independent Americans, perceived Arab confederates (out-group) as farther. A third study directly established the proposed relation between motor effort and distance to human targets: American men perceived other American men as closer after an easy interaction than after a more difficult interaction. Together, these results demonstrate that one and the same sensorimotor mechanism can explain/predict homologous behavioral patterns across the subdisciplines of psychology.

Description
There are several visual dimensions of food that can affect food intake, example portion size, color, and variety. This dissertation elucidates the effect of number of pieces of food on preference and amount of food consumed in humans and motivation for food in animals. Chapter 2 Experiment 1 showed that rats preferred and also ran faster for multiple pieces (30, 10 mg pellets) than an equicaloric, single piece of food (300 mg) showing that multiple pieces of food are more rewarding than a single piece. Chapter 2 Experiment 2 showed that rats preferred a 30-pellet food portion clustered together rather than scattered. Preference and motivation for clustered food pieces may be interpreted based on the optimal foraging theory that animals prefer foods that can maximize energy gain and minimize the risk of predation. Chapter 3 Experiment 1 showed that college students preferred and ate less of a multiple-piece than a single-piece portion and also ate less in a test meal following the multiple-piece than single-piece portion. Chapter 3 Experiment 2 replicated the results in Experiment 1 and used a bagel instead of chicken. Chapter 4 showed that college students given a five-piece chicken portion scattered on a plate ate less in a meal and in a subsequent test meal than those given the same portion clustered together. This is consistent with the hypothesis that multiple pieces of food may appear like more food because they take up a larger surface area than a single-piece portion. All together, these studies show that number and surface area occupied by food pieces are important visual cues determining food choice in animals and both food choice and intake in humans.

Description
National surveys indicate that Americans hold greater prejudice toward atheists than many other historically stigmatized groups. The religious prosociality perspective posits that people will demonstrate prejudice toward anyone who does not believe in a monitoring and punishing god, including atheists, because of the perception that those who lack belief in a monitoring and punishing god cannot be trusted to act in a prosocial manner. The sociofunctional perspective posits that people will demonstrate distinct forms of prejudice toward individuals who present certain types of threats to the group, and previous research suggests that atheists are perceived as posing a threat to group values. In the current study, participants rated targets whose values largely matched their own values more favorably than targets whose values did not largely match their own values. Also, participants rated both targets who believed in a monitoring and punishing god and targets who believed in a god who does not monitor nor punish more favorably than atheist targets. These judgments spanned a variety of measures, including emotional reactions to the target, judgments of target traits, and preferred social distance from the target. Results were consistent with the sociofunctional perspective but did not support the religious prosociality perspective.

Infectious diseases have been a major threat to survival throughout human history. Humans have developed a behavioral immune system to prevent infection by causing individuals to avoid people, food, and objects that could be contaminated. This current project investigates how ambient temperature affects the activation of this system. Because temperature is positively correlated with the prevalence of many deadly diseases, I predict that temperature moderates the behavioral immune system, such that a disease prime will have a stronger effect in a hot environment compared to a neutral environment and one's avoidant behaviors will be more extreme. Participants were placed in a hot room (M = 85F) or a neutral room (M = 77F) and shown a disease prime slide show or a neutral slide show. Disgust sensitivity and perceived vulnerability surveys were used to measure an increased perceived risk to disease. A taste test between a disgusting food item (gummy bugs) and a neutral food item (gummy animals) measured food avoidance. There was no significant avoidance of the gummy and no significant difference in ratings of disgust sensitivity or perceived vulnerability as a function of temperature conditions. There were no significant interactions between temperature and disease. The conclusion is that this study did not provide evidence that temperature moderates the effect of disease cues on behavior.

Description
Men may engage in financially risky behaviors when seeking mates for several reasons: Risky behaviors can signal to potential mates one's genetic fitness, may facilitate success in status competition with other men, and may be a necessary strategy for gaining sufficient resources to offer potential mates. Once in a relationship, however, the same financial riskiness may be problematic for males, potentially suggesting to partners an interest in (extra-curricular) mate-seeking and placing in jeopardy existing resources available to the partner and the relationship. In the current research, we employed guided visualization scenarios to activate either a mating motivation or no motivation in single and in attached men and women. Participants indicated their preference for either guaranteed sums of money or chances of getting significantly more money accompanied by chances of getting nothing. As predicted, mating motivation led single men to become more risky and attached men to become less risky. These findings replicated across different samples and measures. Interestingly, in all three studies, women exhibited the opposite pattern: Mating motivation led single women to become less financially risky and attached women to become more risky. Thus, two additional experiments were conducted to explore the potential causes of this effect. The results of these latter experiments support the "mate-switching" hypothesis of risk-taking in attached women. That is, women who are able (i.e. have high mate value) were more risky in order to exit an undesirable relationship and move into a better one.

Description
People may conceptualize God as benevolent and as authoritarian. This research investigates the influence of these God-concepts on prosocial behavior; specifically whether such concepts differentially predict a set of beliefs about the self and the world, volunteer motivations, and intentions to volunteer for secular causes. Two studies, one correlation and one experimental, were conducted among college students who were Christians and indicated they believe that God exists. A measurement model of the concepts of Benevolent and Authoritarian God was first tested, and a conceptual path model was then analyzed. I found that concepts of a benevolent God were associated with a benevolent self-identity, perceived moral and religious obligations to help, and a high sense of personal responsibility with a total positive indirect effect on intentions to volunteer - mainly via internal motivations. In contrast, concepts of an authoritarian God were associated with a perceived religious obligation, having a positive indirect effect on intentions to volunteer via external motivations; but also with a low benevolent self-identity and low personal responsibility associated with amotivation (the disinclination to volunteer). Thus, there was a null total indirect effect of belief in an authoritarian God on intentions to volunteer. Future directions including the use of religious primes are discussed.

Description
The unpleasant bitter taste found in many nutritious vegetables may deter people from consuming a healthy diet. We investigated individual differences in taste perception and whether these differences influence the effectiveness of bitterness masking. To test whether phenylthiocarbamide (PTC) `supertasters' also taste salt and sugar with greater intensity, as suggested by Bartoshuk and colleagues (2004), we infused strips of paper with salt water or sugar water. The bitterness rating of the PTC strip had a significant positive linear relationship with ratings of both the intensity of sweet and salt, but the effect sizes were very low, suggesting that the PTC strip does not give a complete picture of tasting ability. Next we investigated whether various seasonings could mask the bitter taste of vegetables and whether this varied with tasting ability. We found that sugar decreased bitterness and lemon decreased liking for vegetables of varying degrees of bitterness. The results did not differ by ability to taste any of the flavors. Therefore, even though there are remarkable individual differences in taste perception, sugar can be used to improve the initial palatability of vegetables and increase their acceptance and consumption.

Description
Beliefs about change reflect how we understand phenomena and what kind of predictions we make for the future. Cyclical beliefs about change state that events are in a constant flux, and change is inevitable. Linear beliefs about change state that events happen in a non-fluctuating pattern and change is not commonplace. Cultural differences in beliefs about change have been documented across various domains, but research has yet to investigate how these differences may affect health status predictions. The present study addresses this gap by inducing different beliefs about change in a European-American college sample. Health status predictions were measured in terms of predicted likelihood of exposure to the flu virus, of contraction of the flu, and of receiving a flu vaccine. Most differences were observed among those who have a recent history of suffering from the flu. Among them, cyclical thinkers tended to rate their likelihood for exposure and contraction to be higher than linear thinkers. However, linear thinkers indicated that they were more likely to receive a flu vaccine. The different patterns suggest the possibility that cyclical beliefs may activate concepts related to cautionary behaviors or pessimistic biases, while linear beliefs may activate concepts related to taking action and exercising control over the environment. Future studies should examine the interplay between beliefs about change and the nature of the predicted outcome.

Description
While the concept of healthcare is largely respected in Arab culture, the stigma underlying mental health is particularly startling. This study examined the differences in mental health treatment-seeking behaviors using data from Arabs living in Syria (12.9%) and Arabs (25.6%) and non-Arabs (61.5%) living in the United States of ages 18-60. A Web-based survey was developed to understand how factors like religiosity, acculturation, and positive attitudes towards psychological treatment increased help-seeking behaviors. This survey was also provided in Arabic to include non-English speaking participants. It was hypothesized that Arab-American individuals will be more open to pursuing professional psychological help when suffering from mental symptomology (i.e. anxiety) than individuals who identified as Syrian-Arabs. In contrast, both Syrian-Arabs and Arab-Americans would definitely pursue professional help when suffering from physical symptomology (i.e. ankle sprain). Striking differences were found based on Western acculturation. Findings suggested that Arab-Americans were less inclined towards treatment and more trusting of an in-group physician ("Dr. Ahmed") whereas Syrian-Arabs were more inclined to pursue psychological treatment and preferred to trust an out-group physician ("Dr. Smith"). The results of this study identify main concerns regarding Arab attitudes towards seeking mental health treatment, which can better inform future research and mental health services for this minority.

Statistics are rising for adults who are overweight and/or obese, putting them at higher risk of developing serious health problems. Eating fewer portions of vegetable than the daily-recommended amounts contributes to this increase with. College students, being more susceptible to weight gain as they are transitioning from childhood to adulthood. Previous studies demonstrated that children ate more vegetables when repeatedly paired with a low-fat dip compared to when served plain. The current study examined whether this effect was also successful in college-aged subjects. A total of 148 (55 males, 91 females) college-aged students from an introductory psychology class at Arizona State University (Tempe, AZ) participated in the study. Subjects were randomly assigned to receive cauliflower or broccoli (raw) either served plain or with low-fat ranch dressing. Subjects showed a greater preference for and consumption of the vegetable plain that was previously given with dip than without dip. These findings suggest that serving vegetables with low-fat ranch dip two times can increase the liking and consumption of vegetables in college students.
