Description
In everyday life, mental fatigue can be detrimental across many domains including driving, learning, and working. Given the importance of understanding and accounting for the deleterious effects of mental fatigue on behavior, a growing body of literature has studied the role of executive control processes in mental fatigue. In a laboratory setup, participants complete a task that places demands on executive control processes and are later given a transfer task. Generally speaking, decrements to subsequent task performance are taken as evidence that the initial executive control task created mental fatigue through the continued engagement of executive control. Several hypotheses have been developed to account for negative transfer resulting from executive control depletion including cognitive resource depletion and task-switching. In the current study, we provide a brief literature review, specify current theoretical approaches to depletion, and provide a strong empirical test of theories for negative transfer from executive control depletion (i.e., does continued performance of an executive control task negatively transfer to that exact same task).

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.

Description
Although it has recently been demonstrated that source monitoring (SM) processes may mediate the relationship between working memory (WM) and false memories, little research has investigated whether the quality of monitoring processes can account for this reduction. In the current study, participants performed multiple false memory, WM, and SM tasks. Consistent with previous research, SM abilities mediated the relationship between WM and false memories (regardless of whether or not participants were warned of the illusions at encoding). High SM individuals were better able to recall contextual information from study to correctly reject lures, whereas low SM individuals were more likely to rely on the quality of retrieved details to reject lures. These results suggest that individuals low and high in SM abilities rely on qualitatively different monitoring processes to reduce errors, and that individual differences in diagnostic monitoring strategies may account for previous relationships found between WM and false memories.

Description
This study examined the relation between Religiosity (a motivational system) and Working Memory Capacity (a cognitive system) to determine how they interact to promote goal-directed behavior. Participants completed a religiosity questionnaire and engaged in a battery of tasks that were used to assess their Working Memory Capacity (WMC) and overall ability to maintain goal-directed behavior. The Stroop task was used to examine the participants' ability to maintain goals in the face of interference. It was predicted that religiosity and WMC would be inversely related and that when we controlled for religiosity, WMC would be the only significant predictor of Stroop performance. Furthermore, we hypothesized that religiosity and Stoop would be inversely related, whereas WMC and Stroop would be positively correlated with one another. Religiosity and Stroop performance were each divided into three different components. Religiosity was divided into: Intrinsic Motivation, Extrinsic Motivation, and CARMA. Stroop Performance was measured through Stroop Accuracy, the Stroop Effect, and Post-Error Slowing. The results of our study supported each of our hypotheses. These findings demonstrated that there is a cognitive process underlying motivational systems, such as religion, which affect an individual's ability to sustain goal-directed behavior.

The media often portrays professional basketball players as narcissistic, entitled and selfish, but are these portrayals accurate? After all, basketball is a team sport and team sport research indicates that players are more altruistic and selfless. This study proposes a way to assess narcissism and altruism through observable behaviors from all the active players in the NBA.

Description
Problem solving is a crucial skill needed to accomplish everyday tasks and overcome potential obstacles. One way to measure individual differences in problem solving ability is through performance differences on multiply-constrained problem solving tasks. Multiple cognitive processes are involved in multiply-constrained problem solving. An individual uses prospective metacognitive monitoring judgments to gauge future allocation of resources before engaging in the necessary semantic search. Problem solvers also vary in their semantic search strategies, and use either an active analytical strategy or a passive insight strategy to arrive at asolution. Prospective metacognitive monitoring judgments and solution strategies are two aspects of the problem solving process that occur at specific points in the process while motivation influences problem solving throughout the process. The goal of this study is to examine prospective metacognitive judgments, problem solving accuracy, solution strategy, and motivation in multiply-constrained problem solving. Motivation was manipulated using a performance based monetary incentive. Participants self reported prospective Feeling-of-Knowing judgments after brief exposure to the problem, and solution strategy ratings after each problem. No significant differences were found to support the effect of motivation on problem solving accuracy, prospective metacognitive judgments, relative accuracy, or solution strategies. Significant differences were found between groups when comparing the number of problems skipped, indicating that participants were sensitive to the incentive structure. The findings suggest that motivation may not be an overarching mediator in multiply-constrained problem solving or problem solving may require a specific type of incentive structure to increase accuracy. However, little is known in the research literature about the type of incentive structure needed to consistently increase individual motivation.

Description
A recent controversy has surrounded service dogs in public environments. Use of service dogs may trigger discrimination against individuals with non-visible disabilities. Major goals of this thesis study are to examine if significant differences exist in personality perceptions and attitude towards service dog owners with visible disabilities versus those with non-visible disabilities, and whether these perceptions and attitude predict how they would be treated in a public setting. The study employed a mixed 2 x2 factorial experiment design. The first independent variable was visibility of the disability, with the two levels being visible vs non-visible, and this factor was non-repeated in nature. The second independent variable was the target of evaluation, with the owner and the dog being the two levels, and this was a repeated measure. Specifically, this study assessed personality perceptions using the Big Five personality traits (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience) and operationalized attitude in terms of the positivity of personality perceptions. Additionally, this study examined whether an owner of a service dog with a non-visible disability would be treated differently from their counterpart who has a visible disability. In the study, participants were given a scenario and picture where they encounter an individual who either had a visible or non-visible disability with a service dog at a restaurant. Then, participants rated the owner and the dog individually on the Big Five personality traits, and indicated whether and how likely they would seat the individual and their service dog at the restaurant. When considering the visibility of a disability alone, an individual with a non-visible disability was perceived as less conscientious. When considering how the owner and the dog were perceived regardless of visibility of disability, owners were rated significantly lower than their dog on agreeableness and extraversion, but significantly higher on openness to experience. There was also a significant difference in treatment of the dog owners based on the visibility of their disability, service dog owners with non-visible disabilities have a higher likelihood of experiencing unlawful treatment. Furthermore, personality perceptions and attitude were significantly correlated with treatment for both individuals with non-visible and visible disabilities. Together, findings of this study inform the design of future research. Future research on this topic may help inform policy makers the challenges and unfair treatment facing individuals who have non-visible disabilities.

Description
This thesis study aimed to (1) test whether first-year college students' perceived future self-connectedness predicts their interest in continuing premedical studies, (2) assess whether the presence of academic role models predicts their future self-connectedness and (3) pilot-test an experimental manipulation to increase future self-connectedness and interest in premedical studies. The study included two parts. First, students completed the pre-manipulation measures including future self-connectedness and interest in premed studies. Second, students were randomly assigned to an experimental or a control condition. In the experimental condition, students were asked to imagine that they were licensed doctors and write words of advice to their current selves. In the control condition students were asked to reflect and write about their daily routine. The results from this study showed a significant positive correlation of interest in remaining in premedical studies with both future self-connectedness and the presence of role models and future self-connectedness. Additionally, students in the experimental condition showed a significant increase in future self-connectedness after completing the manipulation. However, their interest in remaining in premedical studies did not change after the manipulation. Together, these findings suggest a method for keeping Freshman undergraduates from dropping out hastily from the premedical track.

Description
In everyday life, unfocused attention can be detrimental to life either through driving vehicles, cutting vegetables, and learning new languages. In order to increase sustained attention, Binaural Beats were introduced. Binaural Beats have two different frequency tones which oscillate to produce different effects. Each of these beats operates at different frequencies thus having different sound production: theta, delta, alpha, beta, and gamma. In the experiment beta Binaural Beats with frequencies of 200 and 216 Hertz, Hz (unit of measurement for frequency), were used with a control of 200 Hz flat noise. The experiment utilized the psychomotor vigilance task to measure changes in response times and utilized Affectiva to measure changes in facial musculature. The response times were then analyzed to explain why the Binaural Beats condition had significantly shorter response times compared to the control group throughout the task. In terms of emotional change, some trends were noticed for the Binaural Beats and the control condition; however, none of the trends were significant. Moving forward with the experiment, an increased number of participants can be recorded to strengthen the validity and test different frequencies of Binaural Beats for accuracy.
