Description
When people pick up the phone to call a telephone quitline, they are taking an important step towards changing their smoking behavior. The current study investigated the role of a critical cognition in the cessation process--self-efficacy. Self-efficacy is thought to be influential in behavior change processes including those involved in the challenging process of stopping tobacco use. By applying basic principles of self-efficacy theory to smokers utilizing a telephone quitline, this study advanced our understanding of the nature of self-efficacy in a "real-world" cessation setting. Participants received between one and four intervention calls aimed at supporting them through their quit attempt. Concurrent with the initiation of this study, three items (confidence, stress, and urges) were added to the standard telephone protocol and assessed at each call. Two principal sets of hypotheses were tested using a combination of ANCOVAs and multiple regression analyses. The first set of hypotheses explored how self-efficacy and changes in self-efficacy within individuals were associated with cessation outcomes. Most research has found a positive linear relation between self-efficacy and quit outcomes, but this study tested the possibility that excessively high self-efficacy may actually reflect an overconfidence bias, and in some cases be negatively related to cessation outcomes. The second set of hypotheses addressed several smoking-related factors expected to affect self-efficacy. As predicted, higher baseline self-efficacy and increases in self-efficacy were associated with higher rates of quitting. However, contrary to predictions, there was no evidence that overconfidence led to diminished cessation success. Finally, as predicted, shorter duration of quit attempts, shorter time to relapse, and stronger urges all were associated with lower self-efficacy. In conclusion, understanding how self-efficacy and changes in self-efficacy affect and are affected by cessation outcomes is useful for informing both future research and current quitline intervention procedures.

Description
Fibromyalgia (FM) is a chronic musculoskeletal disorder characterized by widespread pain, fatigue, and a variety of other comorbid physiological and psychological characteristics, including a deficit of positive affect. Recently, the focus of research on the pathophysiology of FM has considered the role of a number of genomic variants. In the current manuscript, case-control analyses did not support the hypothesis that FM patients would differ from other chronic pain groups in catechol-O-methyltransferase (COMT) and mu-opioid receptor (OPRM1) genotype. However, evidence is provided in support of the hypothesis that functional single nucleotide polymorphisms on the COMT and OPRM1 genes would be associated with risk and resilience, respectively, in a dual processing model of pain-related positive affective regulation in FM. Forty-six female patients with a physician-confirmed diagnosis of FM completed an electronic diary that included once-daily assessments of positive affect and soft tissue pain. Multilevel modeling yielded a significant gene X environment interaction, such that individuals with met/met genotype on COMT experienced a greater decline in positive affect as daily pain increased than did either val/met or val/val individuals. A gene X environment interaction for OPRM1 also emerged, indicating that individuals with at least one asp allele were more resilient to elevations in daily pain than those homozygous for the asn allele. In sum, the findings offer researchers ample reason to further investigate the contribution of the catecholamine and opioid systems, and their associated genomic variants, to the still poorly understood experience of FM.

Description
This research is focused on two separate but related topics. The first uses an electroencephalographic (EEG) brain-computer interface (BCI) to explore the phenomenon of motor learning transfer. The second takes a closer look at the EEG-BCI itself and tests an alternate way of mapping EEG signals into machine commands. We test whether motor learning transfer is more related to use of shared neural structures between imagery and motor execution or to more generalized cognitive factors. Using an EEG-BCI, we train one group of participants to control the movements of a cursor using embodied motor imagery. A second group is trained to control the cursor using abstract motor imagery. A third control group practices moving the cursor using an arm and finger on a touch screen. We hypothesized that if motor learning transfer is related to the use of shared neural structures then the embodied motor imagery group would show more learning transfer than the abstract imaging group. If, on the other hand, motor learning transfer results from more general cognitive processes, then the abstract motor imagery group should also demonstrate motor learning transfer to the manual performance of the same task. Our findings support that motor learning transfer is due to the use of shared neural structures between imaging and motor execution of a task. The abstract group showed no motor learning transfer despite being better at EEG-BCI control than the embodied group. The fact that more participants were able to learn EEG-BCI control using abstract imagery suggests that abstract imagery may be more suitable for EEG-BCIs for some disabilities, while embodied imagery may be more suitable for others. In Part 2, EEG data collected in the above experiment was used to train an artificial neural network (ANN) to map EEG signals to machine commands. We found that our open-source ANN using spectrograms generated from SFFTs is fundamentally different and in some ways superior to Emotiv's proprietary method. Our use of novel combinations of existing technologies along with abstract and embodied imagery facilitates adaptive customization of EEG-BCI control to meet needs of individual users.

Description
Abstract: Behavioral evidence suggests that joint coordinated movement attunes one's own motor system to the actions of another. This attunement is called a joint body schema (JBS). According to the JBS hypothesis, the attunement arises from heightened mirror neuron sensitivity to the actions of the other person. This study uses EEG mu suppression, an index of mirror neuron system activity, to provide neurophysiological evidence for the JBS hypothesis. After a joint action task in which the experimenter used her left hand, the participant's EEG revealed greater mu suppression (compared to before the task) in her right cerebral hemisphere when watching a left hand movement. This enhanced mu suppression was found regardless of whether the participant was moving or watching the experimenter move. These results are suggestive of super mirror neurons, that is, mirror neurons which are strengthened in sensitivity to another after a joint action task and do not distinguish between whether the individual or the individual's partner is moving.

Description
Perhaps by some ingrained sense of human preparedness, phobias are an outlier in the world of conditioning. Again and again, they are highlighted as the only thing which avoidance makes worse, rather than alleviates. My own fear of insects had reached its most severe level just as I began learning about phobias, and avoidance, in my undergraduate psychology courses. There, I learned that avoidance of the phobic stimulus \u2014 in my case, insects \u2014 seemed to be a fundamental element of maintaining a phobia, and I was more than guilty of it. Following this realization, I endeavored into what I would later come to call Stimulus Confrontation: A self-designed therapeutic course of action to overcome my fear. This thesis, then, is the record of this project. It weaves together my scholarly research on phobias with my own personal narrative concerning the employment of Stimulus Confrontation, beginning with the etymology and proposed etiologies of phobias, followed by an overview of contemporary treatment options available and a recounting of Stimulus Confrontation as applied to my own phobia. Told from her own perspective, English writer and journalist Jenny Diski's book, What I Don't Know About Animals, tells of her own arachnophobia, and includes an honest account of the fear and anxiety it caused for her, as well as her own journey to overcome it. Like my own, Diski's phobia \u2014 arachnophobia \u2014 had come to affect her everyday life. Prior to seeking treatment for her fear at the age of 58, Diski too had learned to avoid the thing which she so feared. Inspired by What I Don't Know About Animals, the personal anecdotes I have included throughout this thesis serve to elaborate upon my personal experience with my own insectophobia, and the cessation of avoidance that led to substantial progress in overcoming my fears. Throughout this thesis, I refer to this cessation of avoidance as Stimulus Confrontation, with the intention that following the same process I did may benefit others in overcoming their own specific phobias.

Description
In this study, potential differences in the manifestation and rates of eating disorders and symptoms (body dissatisfaction, weight and shape concerns, food restriction, and compensatory behaviors) in college women across sexual orientations were examined. The sociocultural model of eating disorders was also examined for these women across sexual orientations. The participants were organized into three different sexual orientation groups for analysis: heterosexual (group 1), bisexual, pansexual, and polysexual (group 2), and lesbian, gay, queer, transsexual, asexual, and other (group 3). Using cross-sectional data, it was revealed that there were significant group differences when comparing the three sexual orientation groups on loss of control over eating, but no significant group differences on body dissatisfaction, thin ideal internalization, and weight-related eating pathology, and total eating disorder symptoms scores. The sociocultural model was not predictive of eating disorder symptoms among non-heterosexual groups. Longitudinal analyses revealed that the sociocultural model of eating disorders prospectively predicts eating disorder symptoms among heterosexual women, but not non-heterosexual women. Both cross-sectional and longitudinal analyses indicate that non-heterosexual women may be protected from societal pressure to subscribe to the thin ideal and its subsequent internalization. However, the comparison group of heterosexual women in our study may not have been completely representative of undergraduate women in terms of total eating disorder symptoms or eating pathology. Additionally, regardless of sexual orientation, our sample reported more total eating disorder symptoms and emotional eating than previous studies. These findings have both clinical and research implications. Future research is needed to determine what risk factors and treatment target variables are relevant for non-heterosexual women.

Description
The purpose of this thesis is to examine the relationship between mental illness and capitalist consumer society. Many Americans are suffering from mental illness and there has to be something causing it besides a chemical imbalance in the brain. A capitalist society creates a set of expectations that conflict with human desires. The thesis takes a historical, economical, and psychological approach to answering the following question: Does a capitalist society make its citizens mentally sick? A brief history of capitalism over the past century is discussed, as well as a more in depth look at capitalism and the creation of neoliberalism during the 1980s. The psychological effects capitalism has on human beings is discussed for the majority of the thesis and focuses on ideas from the 1950s as well as the early 2000s. To show the effect capitalism has on modern day society, an analysis of a psychopharmaceutical drug commercial is given. The concluding thoughts attempt to offer solutions to the problems of human unhappiness in a consumer culture.

Description
This correlational study investigated how adolescent's artistic style changed depending on their level of interest in art. The participants were 28 students from the 7th and 8th grade of Zuni Hills Elementary School. A survey was administered which measured, in regards to their artwork, the categories of interest, experimentation in subject, experimentation in material, abstract style, literal style, imagination, identity, emotion and storytelling. It was predicted that interest would have a significant positive relationship with abstract style and experimentation with subject. It was also predicted that interest would have a significant negative relationship with literal style and experimentation with material. Scores for all categories were compared and significant positive relations were found in regards to emotion, identity and storytelling. There was also a significant positive realtionship between interest and imagination as well as interest and emotion. These findings add to research about motivation in adolescent art through the means of expression of the self.

Description
There is preclinical evidence that the detrimental cognitive effects of hormone loss can be ameliorated by estrogen therapy (Bimonte, Acosta, & Talboom, 2010), however, one of the primary concerns with current hormone therapies is that they are nonselective, leading to increased risk of breast and endometrial cancers as well as heart disease. Thus, in order to achieve a successful and clinically relevant long-term hormone therapy option, it is optimal to find an estrogen therapy regimen that is selective to its target tissue. Recently, phytoestrogens have been found to exert selective, beneficial effects on cognition and brain. For example, genistein and diadzein produce neuroprotective effects in cognitive brain regions (Zhao, Chen, & Diaz Brinton, 2002). The purpose of this study was threefold: 1) to examine the cognitive impact of phytoestrogens in young ovariectomized rats, 2) to replicate the dose effects found in the Luine study (Luine et al., 2006), while controlling for manufacturer differences, and 3) to assess if the rodent diet used in our laboratory has an estrogenic-like cognitive impact.The current findings suggest that, at least for object memory, diets containing varying amounts of phytoestrogens can alter cognition, with diets containing high amounts of phytoestrogens showing potential benefits to this type of memory.

Description
This study aims to examine how crossover relations from one parent relate to the other parent's view of familial relationships. The study examines mood state and psychological distress as variables that relate to each other and familial relationships. Home visits were scheduled with families of normally developing three-year olds. During these home visits, naturalistic observation and surveys were done. Researchers then conducted regression analyses to examine the relation between mood state, psychological distress, and familial relationships. The data showed that there were significant relations between one parents' psychological distress and how the other parent viewed the marital relationship, indicating a crossover relation between those two variables.
