Description
This paper considers what factors influence student interest, motivation, and continued engagement. Studies show anticipated extrinsic rewards for activity participation have been shown to reduce intrinsic value for that activity. This might suggest that grade point average (GPA) has a similar effect on academic interests. Further, when incentives such as scholarships, internships, and careers are GPA-oriented, students must adopt performance goals in courses to guarantee success. However, performance goals have not been shown to correlated with continued interest in a topic. Current literature proposes that student involvement in extracurricular activities, focused study groups, and mentored research are crucial to student success. Further, students may express either a fixed or growth mindset, which influences their approach to challenges and opportunities for growth. The purpose of this study was to collect individual cases of students' experiences in college. The interview method was chosen to collect complex information that could not be gathered from standard surveys. To accomplish this, questions were developed based on content areas related to education and motivation theory. The content areas included activities and meaning, motivation, vision, and personal development. The developed interview method relied on broad questions that would be followed by specific "probing" questions. We hypothesize that this would result in participant-led discussions and unique narratives from the participant. Initial findings suggest that some of the questions were effective in eliciting detailed responses, though results were dependent on the interviewer. From the interviews we find that students value their group involvements, leadership opportunities, and relationships with mentors, which parallels results found in other studies.

Description
The purpose of this thesis is to explore if any correlation exists between the proposed components of happiness with overall self-perceived happiness. This thesis also explores how introversion and extraversion, gender, and working status affects the proposed components of happiness for college students and how their happiness influences engagement, motivation, preference of organizational culture, and the activities that they engage in. This research was gathered from secondary sources and a survey that was given to undergraduate students at Arizona State University. We found that well-being, gratitude, achievement, psychological empowerment, and affection contribute to both extraverts and introverts' happiness. In addition, we found that extraverts reported higher means than introverts in each factor; including happiness in general and what contributes to it. Contrary to popular belief, our research shows that autonomy either had no correlation or negatively correlates with happiness. In addition, we found that both extraverts and introverts participate in social and nonsocial activities rather than solely on their expected type of activity. Our research also shows that females reported higher means than males on gratitude, achievement, and autonomy. One significant implication of this study is that it can help individuals to better understand themselves and people they interact with.

Abstract Whether it is an abandoned New Year's Resolution or difficulty controlling procrastination, most can attest to failing to meet a goal. With ubiquitous computing, there is potential to support users' goals on a constant basis with pervasive technology elements such as integrated sensors and software. This study serves as a pilot for the behavior change component of a ubiquitous system, Game as Life, Life as Game (GALLAG), and how goal creation and motivation can be positively altered with the inclusion of a specific framework for users to follow. The study looked to find the efficacy of support tools (goal creation, reflection on past experience, and behavior change techniques and self-tracking) on creating a plan to reach a behavior goal, without the help of technology. Technology was ignored to focus on the effect of a framework for goal and plan generation. Over two weeks, there were 11 participants in the study; data collected was qualitative in the form of three video-recorded interview sessions, with quantitative data in the form of surveys. Participants were presented with support tools and tasked with picking a goal to work towards, as well as creating a plan to reach that goal. It was found that users struggled to create specific and detailed plans, even with the support tools provided, but this improved after the first meeting. Past experience was the most helpful support tool for creating better plans, however participants used this tool before being briefed on it. These results suggest a system should incorporate behavior change, self-tracking, and past experience earlier in the plan creation experience, allowing users a more concrete knowledge of these tools before beginning plan creation. By including these ideas in a framework, GALLAG can later implement that framework to better support users with a physical system.

Description
The predictors of school engagement in early childhood were examined, and mechanisms to improve classroom engagement levels were proposed for interventionists to consider. Literature was reviewed on the relations of child characteristics (i.e. effortful control, negative emotionality) and environmental characteristics (i.e. teacher-child relationship quality, classroom environment) to children's school engagement. Finally, a logic model was developed to guide future intervention work.

Description
Rasopathies are a family of developmental syndromes that exhibit craniofacial abnormalities, cognitive disabilities, developmental delay and increased risk of cancer. However, little is known about the pathogenesis of developmental defects in the nervous system. Frequently, gain-of-function mutations in the Ras/Raf/MEK/ERK cascade (aka ERK/MAPK) are associated with the observed pathogenesis. My research focuses on defining the relationship between increased ERK/MAPK signaling and its effects on the nervous system, specifically in the context of motor learning. Motor function depends on several neuroanatomically distinct regions, especially the spinal cord, cerebellum, striatum, and cerebral cortex. We tested whether hyperactivation of ERK/MAPK specifically in the cortex was sufficient to drive changes in motor function. We used a series of genetically modified mouse models and cre-lox technology to hyperactivate ERK/MAPK in the cerebral cortex. Nex:Cre/NeuroD6:Cre was employed to express a constitutively active MEK mutation throughout all layers of the cerebral cortex from an early stage of development. RBP4:Cre, caMEK only exhibited hyper activation in cortical glutamatergic neurons responsible for cortical output (neurons in layer V of the cerebral cortex). First, the two mouse strains were tested in an open field paradigm to assess global locomotor abilities and overall fitness for fine motor tasks. Next, a skilled motor reaching task was used to evaluate motor learning capabilities. The results show that Nex:Cre/NeuroD6:Cre, caMEK mutants do not learn the motor reaching task, although they performed normally on the open field task. Preliminary results suggest RBP4:Cre, caMEK mutants exhibit normal locomotor capabilities and a partial lack of learning. The difference in motor learning capabilities might be explained by the extent of altered connectivity in different regions of the corticospinal tract. Once we have identified the neuropathological effects of various layers in the cortex we will be able to determine whether therapeutic interventions are sufficient to reverse these learning defects.

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
The RAS/MAPK (RAS/Mitogen Activated Protein Kinase) pathway is a highly conserved, canonical signaling cascade that is highly involved in cellular growth and proliferation as well as cell migration. As such, it plays an important role in development, specifically in development of the nervous system. Activation of ERK is indispensable for the differentiation of Embryonic Stem Cells (ESC) into neuronal precursors (Li z et al, 2006). ERK signaling has also shown to mediate Schwann cell myelination of the peripheral nervous system (PNS) as well as oligodendrocyte proliferation (Newbern et al, 2011). The class of developmental disorders that result in the dysregulation of RAS signaling are known as RASopathies. The molecular and cell-specific consequences of these various pathway mutations remain to be elucidated. While there is evidence for altered DNA transcription in RASopathies, there is little work examining the effects of the RASopathy-linked mutations on protein translation and post-translational modifications in vivo. RASopathies have phenotypic and molecular similarities to other disorders such as Fragile X Syndrome (FXS) and Tuberous Sclerosis (TSC) that show evidence of aberrant protein synthesis and affect related pathways. There are also well-defined downstream RAS pathway elements involved in translation. Additionally, aberrant corticospinal axon outgrowth has been observed in disease models of RASopathies (Xing et al, 2016). For these reasons, this present study examines a subset of proteins involved in translation and translational regulation in the context of RASopathy disease states. Results indicate that in both of the tested RASopathy model systems, there is altered mTOR expression. Additionally the loss of function model showed a decrease in rps6 activation. This data supports a role for the selective dysregulation of translational control elements in RASopathy models. This data also indicates that the primary candidate mechanism for control of altered translation in these modes is through the altered expression of mTOR.

Description
Marijuana is currently the mostly widely used illicit drug in the U.S., and has been for multiple decades (Johnston et. al., 2016). Despite a growing belief that marijuana use is not harmful, over 4 million Americans have met criteria for marijuana use disorders in the past year alone (CBHSQ, 2015). According to marijuana trajectory studies, about a third of marijuana users will end up quitting later in life, but some \u2014 such as those who meet criteria for dependence \u2014 have a much greater difficultly quitting. Therefore, by looking at marijuana users who were successful in quitting, and comparing them to ongoing adult marijuana users, factors that may assist in helping an individual quit \u2014 such as certain motivations for quitting \u2014 may be identified. To study these issues, data was collected from 507 participants from the Pittsburgh Youth Study. It was found that adolescents who used marijuana weekly for at least one year were likely to be ongoing marijuana users in adulthood and that adolescents who had a warm relationship with their primary caretaker were likely to have quit marijuana by adulthood. It was also found that Black participants were more likely to have legal, monetary, and religious reasons for quitting than were White participants. Furthermore, participants who used regularly in adolescence were likely to list legal reasons, as well as a concern that marijuana use was needed to feel normal. Finally, it was found that not a single motivation for quitting marijuana was associated with a shorter period of abstinence. The implications of these findings for motivations to quit marijuana are the focus of the discussion.

Description
The present study examined how systemic low doses of nicotine affect the microstructure of food-reinforced behavior in rats. Rats were given an acute saline or nicotine treatment (0.1-0.6 mg/kg, resting at least 48 h between injections), and a chronic saline or nicotine treatment (0.3 mg/kg for 10 consecutive days). Immediately after treatment, rats were required to press a lever to obtain food, whose availability was unpredictable, but programmed at a constant rate (on average every 80 s). Acute nicotine dose-dependently suppressed behavior prior to the delivery of the first reinforcer, but enhanced food-reinforced behavior afterwards. This effect was primarily observed in the time it took rats to initiate food-seeking behavior, and not in the food-seeking behavior itself. A pre-feeding control procedure suggests that these effects cannot be explained only by changes in appetite. Over the course of chronic nicotine exposure, tolerance developed to the suppressive, but not to the enhancing effects of nicotine on food-seeking behavior. These results suggest that ostensive sensitization effects of nicotine on behavior may instead reflect a tolerance for its suppressive effects on behavior.
