The Role Of Encoding Specificity In Incidental Learning: Implications For Explicit And Implicit False Memories, Cassady Mclaughlin Jan 2019

The Role Of Encoding Specificity In Incidental Learning: Implications For Explicit And Implicit False Memories, Cassady Mclaughlin

Cal Poly Humboldt theses and projects

This research investigated false memories via spreading activation and the influence of encoding specificity on explicit and implicit memory tests in incidental learning situations. It was hypothesized that congruent conditions would have higher rates of both false memories for associated items as well as more accurate memories for presented items. It was also expected that this effect would be larger among those in implicit memory conditions compared to explicit conditions. The participants (n=175) were presented with Deese-Roediger-McDermott semantically associated word lists via a Stroop task, in which they were not told to remember the words presented, but to instead identify …


Get The Fuck Out For A Positive Identity, Bryan Sherburne Jan 2019

Get The Fuck Out For A Positive Identity, Bryan Sherburne

Cal Poly Humboldt theses and projects

The present work examined the conditions under which political partisans would desire to schism from their political party. Drawing on uncertainty-identity theory, the social identity theory of leadership, and the literature on schism, this thesis predicted that under conditions of high uncertainty, partisans would be less likely to schism from their party because they would be willing to accept limits to their voice from political leaders. A broad sample of California Republicans (N = 218) and Democrats (N = 249) were examined using the pretense of either support for or opposition to legislation on DACA enacted by the …


Developmental Disruptions And Substance Use In An Emerging Adult Sample, Nena N. Mcgath Jan 2019

Developmental Disruptions And Substance Use In An Emerging Adult Sample, Nena N. Mcgath

Cal Poly Humboldt theses and projects

Recent substance use reports indicate a rise in use-related deaths. Emerging adults are identified as the most prevalent users of substances when compared to other age groups. Current intervention methods are not universally effective, with relapse rates varying by treatment model. The poor efficacy of interventions may be due to a lack of models using a developmental focus. For example, previous research highlights the influence of adverse childhood experiences (ACEs) on negative adult outcomes such as excessive substance use. ACEs may trigger a cascade of adaptation failures, disrupting attachment bonds between caregiver and child, and later influencing the development of …


Childhood And Trauma: The Effects Of Adverse Childhood Experiences On The Brain, Behavior, And Learning In The Elementary School Classroom, Aeryn Aguilar Jan 2019

Childhood And Trauma: The Effects Of Adverse Childhood Experiences On The Brain, Behavior, And Learning In The Elementary School Classroom, Aeryn Aguilar

Cal Poly Humboldt theses and projects

A variety of studies have been conducted on how trauma, caused by emotional, physical, or verbal abuse, impact children’s lives. Many of the studies which involved observations and assessments were done with the preexisting knowledge that these children had been through a traumatic experience. Instead of looking at behavior of known cases, this study’s goal is to find out whether or not children’s observable behaviors can predict cases of trauma. For example, is acting out or defiance a key sign of trauma or is it part of the typical development for the elementary school-age group? This thesis takes into account …


Biologically Framed Schizophrenia As A Barrier To Belief In Free Will, Nicholas L. Ortiz Jan 2019

Biologically Framed Schizophrenia As A Barrier To Belief In Free Will, Nicholas L. Ortiz

Cal Poly Humboldt theses and projects

Biologically framing mental illness has certain influences on social-psychological processes related to morality and retribution. The attribution of moral responsibility is thwarted when others believe a transgressor has biologically caused mental illness. Belief in free will works as a function for attributing moral responsibility, which represents an intimate, interdependent connection between both concepts. The current study tested whether or not telling participants a transgressor has biologically caused schizophrenia reduces the belief she is morally responsible, has free will, and reduces general belief in free will. Results found partial evidence to show biologically framing a transgressor’s schizophrenia can diminish belief in …


Phonetic Convergence And Auditory Imagery In Reading, Josue E. Rodriguez Jan 2019

Phonetic Convergence And Auditory Imagery In Reading, Josue E. Rodriguez

Cal Poly Humboldt theses and projects

This study aimed to address whether phonetic convergence (speech imitation) and auditory imagery in reading are fundamentally governed by the same process — episodic encoding (c.f., Goldinger, 1998). A set of participants (talkers; N = 12) were recorded speaking sentences at a baseline level. Talkers were then exposed model speaker with either a fast or slow speech rate and then engaged in a reading phase where they read sentences thought to be written by that speaker. If episodic encoding predicts effects of phonetic convergence and auditory imagery in reading style, then talkers should be influenced by a speaker …


The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter Jan 2019

The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter

Cal Poly Humboldt theses and projects

Combined oral contraceptive (COC) pills are widely used by women of reproductive age, but there is still little conclusive evidence that exists about the mood-related side effects associated with their use. This meta-analysis examined the relationship between oral contraceptive use and mood effects such as depression and anxiety to determine what role, if any, that COCs may have in the worsening or improvement of women’s mood when taking them. Effect sizes compared the differences in women’s mood scores before taking COCs and after one or more cycles of use. Seventeen studies made up of 25 individual samples contributed 71 effect …


The Effects Of C-Tactile Afferent Stimulation On Male Orgasm And Ejaculation, Yacoub Ayed Innabi Jan 2019

The Effects Of C-Tactile Afferent Stimulation On Male Orgasm And Ejaculation, Yacoub Ayed Innabi

Cal Poly Humboldt theses and projects

Orgasms and ejaculation are important for relationships and contribute significantly to life satisfaction. There is, however, a lack of research in the current literature regarding orgasm perception. This study tested the effects of endogenous oxytocin on subjective orgasm intensity, ejaculation latency, and ejaculate volume in men. At two separate test sessions, the participants were either stroked on the forearm (to release endogenous oxytocin) or tapped on the hand (to act as a control) with a cosmetic brush. The forearm contains C-tactile afferents that are believed to release oxytocin centrally and peripherally in response to slow, soft stroking stimulation. Then a …


Masculine Norms, Psychological Symptom Severity, And Intentions To Seek Formal Help In Male College Students, Zahra S. Shine Jan 2019

Masculine Norms, Psychological Symptom Severity, And Intentions To Seek Formal Help In Male College Students, Zahra S. Shine

Cal Poly Humboldt theses and projects

Research has consistently found men to be less likely than women to seek help for mental health symptoms. Additionally, greater symptom severity is related to higher levels of help seeking, although this relationship is less clear among men. Greater conformity to masculine norms may help to explain the relationship between symptom severity and help seeking among men. The present study aimed to further research on men’s help-seeking by examining whether conformity to masculine norms would moderate the relationship between symptom severity and help-seeking intentions in male college students (N = 89). A multiple regression analysis was conducted with all …


Eye Movements For Learned Faces, Mariah Lehnertz Jan 2019

Eye Movements For Learned Faces, Mariah Lehnertz

Cal Poly Humboldt theses and projects

Humans demonstrate a perceptual specialization for faces that is astonishing. This project attempts determine if and where within the perceptual process face perception and face recognition diverge at the level of eye movement behaviors. Participants were exposed to a series of 36 faces, of which six were randomly selected to be learned over five subsequent exposures; thus the same face identities served as both the novel faces (block 1) and the learned faces (block 5), allowing for the measurement of eye gaze patterns during initial face perception (novel) and face recognition (learned). These six faces were randomly assigned to different …


"I See Gay People" Gaydar Abilities In A Real-World Distribution, Benjamin Patrick Skillman Jan 2019

"I See Gay People" Gaydar Abilities In A Real-World Distribution, Benjamin Patrick Skillman

Cal Poly Humboldt theses and projects

“Gaydar” is the colloquial term for identifying someone’s sexual orientation from physical cues. Past literature has shown that people can identify someone’s sexual orientation at above chance levels. Past literature has used a 50/50 split of gay and straight faces and used non-standardized images, which can induce confounds in the results. The present study examined gaydar accuracy in a realistic distribution of straight and gay faces using standardized images and examined facial morphology for differences between gay and straight men. Participants were not found to have above chance accuracy for identifying gay faces. PCA did not identify reliable shape differences …


Bully-Victimization, Depression, And School Connectedness In Early Adolescent Students, Irene Gonzalez-Herrer Jan 2019

Bully-Victimization, Depression, And School Connectedness In Early Adolescent Students, Irene Gonzalez-Herrer

Cal Poly Humboldt theses and projects

During early adolescence, schools play a significant role in the development of students. An issue that continues to be a serious concern for students, parents, teachers, and school officials in the U.S. and around the world is bullying. The primary purpose of this study was to examine school connectedness as a mediator between bully-victimization and depressive symptomatology in early adolescence. The secondary purpose of the study was to explore how gender and bullying classification groups (i.e., bully, victim, bully-victim, and non-involved) may relate to levels of reported school connectedness. The current study found low school connectedness partially mediated the relationship …


The Role Of Prototypicality Threat In Men's Evaluations Of Transgender Women, Alexandria Jaurique Jan 2019

The Role Of Prototypicality Threat In Men's Evaluations Of Transgender Women, Alexandria Jaurique

Cal Poly Humboldt theses and projects

All social groups have a prototype that provides a guideline of behaviors and attitudes that embody what it means to be a member of that group (Hohman et al., 2017). Men as a gender group are no exception to the use of a prototype as a basis for evaluating group members (Marques & Páez, 1994). When a man feels like a non-prototypical group member (i.e., peripheral) he is more likely to derogate deviant ingroup members compared to outgroup members. This is because peripheral group members are more likely to engage in behaviors aimed at achieving and maintaining a positive social …


Reserve, Symptoms, Sex, And Outcome Following A Single Sports-Related Concussion, Summer A. Thornfeldt Jan 2019

Reserve, Symptoms, Sex, And Outcome Following A Single Sports-Related Concussion, Summer A. Thornfeldt

Cal Poly Humboldt theses and projects

Reserve refers to the biological/cognitive differences between individuals that protect against cognitive changes following a single sports-related concussion (SRC). A single SRC can lead to brain damage and a loss of reserve. The ImPACT is a neurocognitive test which was used as a proxy for reserve. The Post-Concussion Symptom Scale (PCSS), a symptom checklist, was used to examine symptoms. It was hypothesized that pre-SRC reserve would affect post-SRC reserve, so that those with higher pre-SRC reserves would demonstrate less change in their reserve after a single SRC compared to those with low pre-SRC reserves. It was also hypothesized that females …


The Relationship Between Personality Characteristics And Creativity On Judgements Of Facial Attractiveness, Zhelin Wu Jan 2019

The Relationship Between Personality Characteristics And Creativity On Judgements Of Facial Attractiveness, Zhelin Wu

Cal Poly Humboldt theses and projects

People may or may not realize that when they meet a physically attractive person, they are more likely to evaluate him or her as a smart and positive person compared to a less attractive person in the absence of other features besides physical attractiveness. This attractive halo effect has influenced multiple areas that include the job market, dating, and academic success. However, it is possible for other factors, such as one’s creativity and personality to affect one’s judged attractiveness level. The purpose of this study is to investigate the impact of facial attractiveness, creativity, and warm-cold personality characteristics when judging …


Addressing Divergent Audiences In Conservation Communication: An Examination Of Land Trust Websites In Northern California, Tova Fleming Jan 2019

Addressing Divergent Audiences In Conservation Communication: An Examination Of Land Trust Websites In Northern California, Tova Fleming

Cal Poly Humboldt theses and projects

In a world rich with a diversity of stories and values, successful conservation must not rely on everyone thinking and feeling the same way. Values are the foundation of the cognitive hierarchy of human behavior and are relatively fixed and unlikely to change. As a result, environmental communication that is reliant on a particular set of values may cause polarization around conservation issues. The reasoned action approach offers a way to explore communication techniques that address the cognitive hierarchy of human behavior at its most malleable point, behavioral intentions. Because land trusts work with historically divergent audiences who are often …
