Nicotine has both unconditioned and conditioned stimulus properties. Conditioned stimulus properties of nicotine may contribute to the tenacity of nicotine addiction. The purpose of this experiment was to use neurohistochemical analysis of rapidly developing c-Fos protein to elucidate neurobiological loci involved in the processing of nicotine as an interoceptive conditioned stimulus (CS). Rats were injected (SC) in an intermixed fashion with saline or nicotine (16 sessions of each) and placed in conditioning chambers where they were given one of the three conditions depending on group assignment: (a) nicotine paired 100% of the time with intermittent access to sucrose (nicotine-CS condition), …

Thank You, Dear: Examining The Association Between Gratitude And Relationship Well-Being, Erica Pearse Ragan
Electronic Theses and Dissertations
The current study replicated and extended existing research on gratitude by examining the ways in which gratitude is related to both individual and relationship well-being. A total of 387 participants completed the pre assessment and were randomized into the study, with 251 participants completing the full study (i.e., pre, post, and follow-up assessments). Participants were randomly assigned to list relationship-focused gratitudes, amusing events, or general events that happened during their day for 14 days. The differential impact of the three interventions on both individual and relationship variables was investigated. The relationship-focused and general events conditions experienced decreased negative affect from …

The Mythology Of Game Theory, Mathew D. Mccubbins, Mark Turner, Nick Weller
Faculty Scholarship
Non-cooperative game theory is at its heart a theory of cognition, specifically a theory of how decisions are made. Game theory's leverage is that we can design different payoffs, settings, player arrays, action possibilities, and information structures, and that these differences lead to different strategies, outcomes, and equilibria. It is well-known that, in experimental settings, people do not adopt the predicted strategies, outcomes, and equilibria. The standard response to this mismatch of prediction and observation is to add various psychological axioms to the game-theoretic framework. Regardless of the differing specific proposals and results, game theory uniformly makes certain cognitive assumptions …

The Theory Of Minds Within The Theory Of Games, Mathew D. Mccubbins, Mark Turner, Nicholas Weller
Faculty Scholarship
Classical rationality as accepted by game theory assumes that a human chooser in a given moment has consistent preferences and beliefs and that actions result consistently from those preferences and beliefs, and moreover that these preferences, beliefs, and actions remain the same across equal choice moments. Since, as is widely found in prior experiments, subjects do not follow the predictions of classical rationality, behavioral game theorists have assumed consistent deviations from classical rationality by assigning to subjects certain dispositions— risk preference, cognitive abilities, social norms, etc. All of these theories are fundamentally cognitive theories, making claims about how individual human …

The Processing And Content Of Family Narratives In Emerging Adulthood: Gender, Family Functioning, And Associations With Identity Development, Sarah Morrison-Cohen
WWU Graduate School Collection
The aim of the present study was to examine the family narratives of emerging adults. While previous studies have found that interpretative narrative content in adolescents' family narratives is related to identity development, this relation has not been explored in emerging adulthood. One hundred and fifty-eight university students, most in their first year, were asked to provide written narratives of times for the family that were happy, difficult, or transitional, as well as a narrative about themselves commonly told by the family. I examined the relationship between interpretive processing and identity within and across these narrative types, controlling for family …

Predictors Of Bullying In An Adolescent School Sample, Schell Hufstetler
Electronic Theses and Dissertations
Author's abstract: Bullying is a pervasive problem in our society. Contributing to this problem is the fact that bullying is not well understood. This makes it difficult to design successful interventions. The current study aims to create a complete picture of bullying in order to increase understanding of this behavior. For this study, 59 adolescents completed a survey packet including measures of bullying behaviors and other variables expected to relate to bullying. The results revealed that bullying is a problem for both genders. Multivariate analyses revealed males to be more directly and indirectly aggressive, but there were no significant gender …

Self-Silencing Among Punjabi Women: The Interplay Of Cultural Adaptation, Depression, And Domestic Violence, Madhura Bhadra
WWU Graduate School Collection
Silencing the self theory predicts that women in oppressive relationships tend to experience loss of self through self-silencing, and are therefore more prone to depression. Past studies have found that both abuse and immigration are associated with higher levels of self-silencing and depression. The current study investigated the psychometric properties of the Silencing the Self Scale (STSS) and the Beck Depression Inventory II (BDIII), as well as the validity of the STSS subscales for a specific cultural population. Fifty-five Punjabi women completed the STSS, the BDI-II, and participated in in-depth focus groups for a mixed methods approach to a culturally …
Effects Of Social Support Visibility On Cardiovascular And Emotional Responses During An Acute Stress Task,

Effects Of Social Support Visibility On Cardiovascular And Emotional Responses During An Acute Stress Task, Julie A. Kirsch
WWU Graduate School Collection
In contrast to invisible (unacknowledged) social support, visible social support tasks produce exaggerated negative emotional responses. Processes such as social comparison and negative social evaluation confound operationalizations of visible social support. This study tested social support visibility independent of negative social evaluation and social comparison processes, and included cardiovascular responses. Female undergraduates (N = 73) participated in an anticipatory speech task. A female confederate provided either visible or invisible social support, or no social support. Negative emotions were not affected by the social support manipulations. Cardiovascular outcomes were tested by incorporating a series of theoretically driven planned contrasts into tests …

The Impact Of Magnetic Resonance Imaging On Juror Perceptions Of Guilt, Christopher M. (Christopher Michael) Jackson
WWU Graduate School Collection
This study examined the impact of MRI-based evidence on juror perceptions of guilt in a criminal case. Jury eligible undergraduates read one of three mock trial summaries of a murder case wherein MRI evidence was manipulated: (1) MRI evidence with accompanying neuroimages, (2) MRI evidence without accompanying brain images, or (3) no MRI evidence. The proportion of guilty verdicts rendered was statistically similar across all conditions. In addition, participants did not list MRI evidence as the most influential piece of evidence for their verdict. Based on the results of this study it appears that MRI-based evidence and neuroimages do not …

Motivation, Need Support And Need Satisfaction In Youth Soccer Players, Erica Lippitt
Electronic Theses and Dissertations
Author's abstract: Physical activity levels and obesity rates vary greatly across ethnic groups in the United States (CDC, 2011). One popular way to increase physical activity levels in youth is through youth sport participation, which may be influenced by athlete motivation. Numerous studies have determined motivation levels in youth sport participants, but very little done in comparing levels across different ethnic groups. Identifying differences in motivation levels based on ethnicity can allow coaches and sport administrators to adjust practices and program setups to increase participation and meet needs of player competence. The purpose of the study was to determine if …

Online Selection Of Alternating Subsequences From A Random Sample, Alessandro Arlotto, Robert W. Chen, Lawrence A. Shepp, J. Michael Steele
Statistics Papers
We consider sequential selection of an alternating subsequence from a sequence of independent, identically distributed, continuous random variables, and we determine the exact asymptotic behavior of an optimal sequentially selected subsequence. Moreover, we find (in a sense we make precise) that a person who is constrained to make sequential selections does only about 12 percent worse than a person who can make selections with full knowledge of the random sequence.

Parental Factors Impacting Neurobehavioral Late Effects In Latino Pediatric Cancer Survivors, Pamela R. Perez
Loma Linda University Electronic Theses, Dissertations & Projects
While the survival rate for children with cancer has increased markedly over the past 50 years, the side effects resulting from cancer and cancer treatment have become a major concern for health care providers and families alike. Survivors of childhood cancers are at risk for late occurring sequelae, called late effects, which are associated with disease, chemotherapy, radiation, and surgery. Neurobehavioral late effects are some of the most debilitating late effects found, particularly in survivors of central nervous system (CNS) cancers. The purpose of this study was to explore the impact of clinical and socio-demographic parenting factors on neurological late …

The Effects Of Observers’ Expectations And The Probability Of A Change Occurring On Change Detection Performance, Robert A. Brown
Doctoral Dissertations and Master's Theses
The change probability effect is a term coined by Beck et al. (2004) and it suggests that changes that are expected or "probable" are detected more easily than changes that are unexpected or "improbable". This research study investigates the change probability effect and the differences between observers who are looking for changes and those who are unaware that changes may exist. The results suggest that observers who are not expecting a change to occur are more likely to detect an improbable change than a probable change. The findings from this study have real world applications and also have implications for …

Living Large: The Powerful Overestimate Their Own Height, Michelle M. Duguid, Jack A. Goncalo
Jack Goncalo
Three experiments tested the prediction that individuals’ experience of power influences perceptions of their own height. Power decreased judgments of an object’s height relative to the self (Study 1), made participants overestimate their own height (Study 2) and caused participants to choose a taller avatar to represent them in a second-life game (Study 3). These results emerged regardless of whether power was experientially primed (Study 1 and 3) or manipulated through roles (Study 2). Although a great deal of research has shown that physically imposing individuals are more likely to acquire power, this work is the first to show that …

Spurious Also? Name-Similarity Effects (Implicit Egotism) In Employment Decisions, Uri Simonsohn
Operations, Information and Decisions Papers
Implicit egotism is the notion that major life decisions are influenced by name-similarity. This paper revisits the evidence for the most systematic test of this hypothesis. Anseel & Duyck (2008) analyzed data from 1/3 of all Belgian employees and found that a disproportionate fraction of them shared their initial with their employer. Using a data set with American employees I replicate the finding, but new analyses strongly suggest they are due to reverse causality, whereby the documented effect seems to be driven by people naming companies they start after themselves rather than by employees seeking out companies they have a …

Individual Differences In Zebrafish (Danio Rerio) Behavior: Implications For Personality, Christina Nicole Toms
Master's Theses
Individual differences (IDs) in zebrafish (Danio rerio) behavior were examined across time and contexts in order to investigate personality traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three constructs. There was …

The Relations Among Laterality, Cortisol, And Approach-Avoidance Behavior In Garnett's Bushbaby (Otolemur Garnettii), David Burton Hanbury
Dissertations
Many studies to date have demonstrated that approach and avoidance behaviors are processed asymmetrically in the brain and may be reflected in measures such as handedness. The purpose of this study was to extend work in primates on this topic to Garnett’s bushbaby, a prosimian species. Furthermore, to determine whether measures in addition to handedness relate to approach-avoidance behavior, lateralized differences in tympanic membrane temperature were assessed. Cortisol measures were also obtained to determine whether it was related approach-avoidance behavior and handedness. Eleven captive-born Garnett’s bushbabies (Otolemur garnettii) were evaluated for handedness and responsiveness to novelty. Moreover, the …

The Effect Of Improvisations And Observations On Standardized Patient Encounters, Subjective Workload And Stress, Elizabeth T. Newlin-Canzone
Psychology Theses & Dissertations
Standardized patients (SPs) are people trained to present a medical case for teaching and assessing medical students and they simultaneously perform several demanding tasks including portraying the patient, assessing the learner, and providing feedback. This study investigated the effect of improvisations and multiple task performance on the ability to observe another's nonverbal (NV) behaviors and rate their communication skills. Subjective reports of mental workload and stress were also obtained. The first study involved undergraduates interviewing for a job. Type of interview (rote and improvisational) and type of observation (passive and active) were manipulated within groups. Based on theories of attention …
