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
My work focuses on the themes of grief, closure, and celebration of life. Life is a catalyst both celebration and grief. Feeling joy when a life is introduced is as common as feeling pain when a life is lost. When I lost my maternal grandmother nearly a year ago, I felt grief accompanied with guilt. I never got a chance to say goodbye since we lived so far apart, her residing in the Philippines and me residing in the United States. In order to get rid of these negative emotions, I sought closure. I attended her funeral, and now I want to celebrate her life through my artwork.
My work comes in two parts: an illustration book titled The Butanding and an illustration exhibition. The book will be published through lulu.com and made available to the public. The exhibition component will be held from March 2nd to March 6th in Gallery 100 as part of my senior exhibition Post Pre-Production with six other colleagues in the School of Art. The illustration book is a narration of a little girl and her growing friendship with a whale shark. The overarching theme of the creative project is closure with the passing away of loved ones.
The Butanding is a narrative illustration book about a young girl befriending the local menace of her village, the whale shark. Similar to my own experience, the main subject—the young girl—of my narrative is shown suffering from grief and guilt over her grandmother’s death. My work illustrates a progression of the young girl’s emotional state as she goes on a journey with the whale shark or locally known in the Philippines as the “butanding”. It provides the scenario of a grieving individual who gets the chance to reconnect with a deceased loved one and rebuild relationships that were lost.

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.

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
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.

Description
Highly publicized cases involving citizen fatalities due to police use of force raise questions about perceptions of danger. Arrest-related deaths due to weapons, accidental injuries, and natural causes remain high year after year. Communities are greatly affected, and mistrust with the police continues to increase when these situations happen. There seem to be inaccurate perceptions that may stem from implicit associations, stereotypes, and social learning. These psychological concepts may provide theoretical explanations of how decisions are made when police officers are faced with danger. Some elements of this decision-making process may include suspect characteristics, officer experience, and police sub-culture. In this review, race/ethnicity and socio-economic status are examined as factors that contribute to police use of force. Disparities in use of force data often involve young, Black males living in low-income neighborhoods. The stereotype that this group is more dangerous than others stems from underlying prejudices and previous situations where Black people are targeted more in certain areas. Training, education, and community outreach programs can assist in mending relations between police and affected communities. Acknowledging these inaccurate perceptions, making the adjustments to police training and community relations, and being open to exploration in future research of other minority groups will assist in eliminating prejudices and creating better connections between law enforcement and the community.

Description
Synesthesia is a psychological phenomenon in which the stimulation of one sensory modality brings about a response from at least one other modality. There has now been about two centuries of official synesthesia research, yet the current era of study, about the 2000s on, has proven invaluable to our further understanding of how synesthesia works in our perceptive world. I myself have two forms of synesthesia: color-grapheme and lexical-gustatory. In this paper, I look back on my personal experience with synesthesia and review its history and its operational definitions and theories. I then aim to perform a small case study on my synesthesia, using current research to evaluate my observations. I believe synesthesia has the ability to tell us much about perception, subjectivity, language, and consciousness, and I investigate the potential implications that studying synesthesia could have for some of these fields.

Description
The desire for normalcy is constant, regardless of how unattainable one knows it is. As it seems, the harder one tries for a normal life, the harder it becomes to find it. The more life I experience, the more I realize that normalcy is a construct, completely based in generalizable concepts. Normal will vary from person to person, and even within that, life always provides plenty of deviations from the norm. Within those deviations lies trauma. Trauma is difficult to handle, period. It is even more difficult to handle alone. You Can't Cry While Drinking (Coffee) follows a collegiate arts student as she strives for normalcy while dealing with her mother's terminal diagnosis. This piece focus on alienation, mental health, relationships between women, and the damage that ignoring trauma can cause. It views her actions through the lens of comedy, as laughter can convey a vast and accessible range of emotions. Throughout my college career, I have gone through a significant amount of life stressors, beyond the traditional college work load. Instead of becoming overcome with grief from the traumas I have dealt with, I decided to analyze my life from an outside perspective, taking pieces to share with others. In my observations and experience, sharing stories of hardships with others is mutually beneficial. It allows the individual to come to terms with what they have experience while allowing others to not feel alone if they are struggling with their own lives. There is a considerable amount of comfort in the realization that one does not have to go through traumatic experiences alone. This creative project was performed March 2nd through the 5th. The public exposure was a substantial portion of the process, as sharing trauma was integral to the study of this thesis.
