Description
The purpose of this thesis study was to examine whether the "war on cancer" metaphor influences cancer perception and treatment decision. A total of 249 undergraduates (152 females) from a large southwestern university participated in an online survey experiment and were either randomly assigned to the control condition (N=123) or to the war prime condition (N=126). Participants in the control condition did not receive the metaphor manipulation while participants in the war prime condition received the subtle "war on cancer" metaphor prime. After the prime was given, participants read a scenario, answered questions related to the situation, and responded to demographic questions. The results suggested that, compared to participants in the no-prime condition, participants exposed to the war metaphor were more likely to (a) view melanoma as an acute disease, (b) choose chemotherapy over molecular tests, and (c) prefer more aggressive treatment. These findings illustrated the unintended consequences of the "war on cancer" slogan. The results were encouraging and in the predicted direction, but the effect size was small. The discussion section described possible future directions for research.

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.

Previously we found that subjects ate less from a four-piece bagel than from the same bagel served whole. Here, we determined if subjects differed in their perception of the amount of food based on the number of pieces of food served and measured the effects of these judgments on the amount of food consumed. A total of 213 (140 male, 73 female) undergraduate students with a mean age of 19 years participated in this study. Subjects were shown a whole food and the same food cut into pieces and asked which they perceived to be larger either before or after consuming that food, or not asked at all. We found that subjects ate less from a whole bagel than from a four-piece bagel. Furthermore, significantly more subjects perceived the whole bagel to be more food when asked this question after consumption of the bagel than before. People may be more familiar with the amount of satiation expected from a whole bagel than the four-piece bagel and this perceptual bias may be influenced by recent exposure to food, which ultimately may affect food intake.

What characteristics do people prefer in potential mates? Previous studies have explored this question, discovering that preferred characteristics vary by people's sex and sexual strategy, but have implied that these preferences remain constant across the lifespan. We suggest, however, that systematic variation exists in individuals' mate preferences across the lifespan, as they shift their investments from mating toward parenting. We suggest that the characteristics of a potential mate can be viewed as affordances that assist or hinder an individual in achieving certain fundamental goals. Incorporating the framework of Life History Theory with this affordance-management approach to social behavior, we propose that an individual's life stage, sex, and life history strategy together serve as the basis for these goals and thereby shape the characteristics people seek in potential mates. Using data collected from participants aged 18-45 recruited on Amazon's Mechanical Turk, we tested a range of hypotheses derived from our approach. In general, results provide mixed support for a role of life stage in shaping mate preferences. For example, nurturance and social competence were viewed as more necessary characteristics in a mate by participants invested in parenting. Moreover, as their investment in mating increased, females expressed a greater preference for ambition in their potential mates, but males did not. Other predictions were not borne out, however, suggesting that there is still much to be learned from investigating the relationship between life stage and mate preferences.

Description
Introspective awareness refers to direct access to one’s own internal and subjective thoughts and feelings (Wimmer & Hartl, 1991). Two theories, simulation theory and theory-theory, have been used to understand our access to our mental states. Simulation theory (Harris, 1991) involves imagining yourself in another person’s situation, reading off of your mental state, and attributing that state to the other person. Theory-theory (Gopnik, 1993) involves an interrelated body of knowledge, based on core mental-state constructs, including beliefs and desires, that may be applied to everyone—self and others (Gopnik & Wellman, 1994). Introspection is taken for granted by simulation theory, and explicitly denied by theory-theory. This study is designed to test for evidence of introspection in young children using simple perception and knowledge task. The current evidence is against introspective awareness in children because the data suggest that children cannot report their own false beliefs and they cannot report their on-going thoughts (Flavell, Green & Flavell, 1993; Gopnik & Astington, 1988). The hypothesis in this study states that children will perform better on Self tasks compared to Other tasks, which will be evidence for introspection. The Other-Perception tasks require children to calculate the other’s line of sight and determine if there is something obscuring his or her vision. The Other-Knowledge tasks require children to reason that the other’s previous looking inside a box means that he or she will know what is inside the box when it is closed. The corresponding Self tasks could be answered either by using the same reasoning for the self or by introspection to determine what it is they see and do not see, and know and do not know. Children performing better on Self tasks compared to Other tasks will be an indication of introspection. Tests included Yes/No and Forced Choice questions, which was initially to ensure that the results will not be caused by a feature of a single method of questioning. I realized belatedly, however, that Forced Choice was not a valid measure of introspection as children could introspect in both the Self and Other conditions. I also expect to replicate previous findings that reasoning about Perception is easier for children than reasoning about Knowledge.

Description
The United States has become home to the largest incarcerated population in the world, containing 25% of the world's prisoners (NAACP, 2013). Within this population, young men of color appear to be severely overrepresented. This phenomenon can be better understood with the aid of a multi-disciplinary approach within the social sciences. Evolutionary theory is combined with multiple psychological and sociological perspectives, in order to more deeply understand the multi-level intersection of prejudice and discrimination against society's disadvantaged or vulnerable populations. A synthesis of the multiple theoretical angles of social dominance theory, affordance management, and life history theory is used to suggest a threat-based, attributional framework for understanding punitive decision-making and policy support. This conceptualization also considers the importance of the legal system in effecting social change. Future research within the legal arena is recommended to enable a more refined understanding of punitive ideology and implicit bias within the criminal justice system.

Description
Sport is a widespread phenomenon across human cultures and history. Unfortunately, positive emotions in sport have been long vaguely characterized as happy or pleasant, or ignored altogether. Recent emotion research has taken a differentiated approach, however, suggesting there are distinct positive emotions with diverse implications for behavior. The present study applied this evolutionarily informed approach in the context of sport to examine which positive emotions are associated with play. It was hypothesized that pride, amusement, and enthusiasm, but not contentment or awe, would increase in Ultimate Frisbee players during a practice scrimmage. Further, it was hypothesized that increases in pride and amusement during practice would be differentially associated with sport outcomes, including performance (scores, assists, and defenses), subjective social connectedness, attributions of success, and attitudes toward the importance of practice. It was found that all positive emotions decreased during practice. It was also found that increases in pride were associated with more scores and greater social connectedness, whereas increases in amusement were associated with more assists. The present study was one of the first to examine change in positive emotions during play and to relate them to specific performance outcomes. Future studies should expand to determine which came first: emotion or performance.

Description
In recent years, the number of applications for admission to graduate education programs has increased. Researchers attempted to gain insight into this increase by examining student perception of the costs and benefits of pursuing graduate-level education. In order to gauge this perception, researchers administered an online survey to 151 subjects from Barrett, the Honors College at Arizona State University. Student perception was then compared to data released by ASU detailing actual costs and benefits of obtaining graduate-level education. Researchers' prediction that increased levels of parental education would be associated with more accurate estimates of the benefits of graduate-level education was correct at a statistically significant level. Further, being male was statistically significantly associated with an increase in starting salary overestimation.

Description
Tempo control is a crucial part of musicianship that can provide an obstacle for novice musicians. The current study examines why novice percussionists increase their playing tempo when they increase their loudness (in music, loudness is referred to as dynamics). This study tested five hypotheses: 1) As actual tempo changes, listeners perceive that the tempo is changing; 2) There is a perceptual bias to perceive increases in acoustic intensity as also increasing in tempo; 3) All individuals, regardless of percussion experience, display the bias described in hypothesis 2; 4) Unskilled or non-percussionists increase or decrease produced tempo as they respectively increase or decrease loudness; and 5) Skilled percussionist produce less change in tempo due to changes in loudness than non-percussionists. In Experiment 1, percussionists and non-percussionists listened to metronome samples that gradually change in intensity and/or tempo. Participants identified the direction and size of their perceived tempo change using a computer mouse. In Experiment 2, both groups of participants produced various tempo and dynamic changes on a drum pad. Our findings support that both percussionists and non-percussionists, to some extent, display a perceptual bias to perceive tempo changes as a function of intensity changes. We also found that non-percussionists altered their tempo as a function of changing dynamic levels, whereas percussionists did not. Overall, our findings support that listeners tend to experience some integrality between perceptual dimensions of perceived tempo and loudness. Dimensional integration also persists when playing percussion instruments though experience with percussion instruments reduces this effect.

Description
Human perceptual dimensions of sound are not necessarily simple representations of the actual physical dimensions that make up sensory input. In particular, research on the perception of interactions between acoustic frequency and intensity has shown that people exhibit a bias to expect the perception of pitch and loudness to change together. Researchers have proposed that this perceptual bias occurs because sound sources tend to follow a natural regularity of a correlation between changes in intensity and frequency of sound. They postulate that the auditory system has adapted to expect this naturally occurring relationship to facilitate auditory scene analysis, the tracking and parsing sources of sound as listeners analyze their auditory environments. However, this correlation has only been tested with human speech and musical sounds. The current study explores if animal sounds also exhibit the same natural correlation between intensity and frequency and tests if people exhibit a perceptual bias to assume this correlation when listening to animal calls. Our principal hypotheses are that animal sounds will tend to exhibit a positive correlation between intensity and frequency and that, when hearing such sounds change in intensity, listeners will perceive them to also change in frequency and vice versa. Our tests with 21 animal calls and 8 control stimuli along with our experiment with participants responding to these stimuli supported these hypotheses. This research provides a further example of coupling of perceptual biases with natural regularities in the auditory domain, and provides a framework for understanding perceptual biases as functional adaptations that help perceivers more accurately anticipate and utilize reliable natural patterns to enhance scene analyses in real world environments.
