Stress-Induced Oxytocin Reactivity As A Predictor Of Daily Support Seeking After Stress, Cecile Sunahara Jan 2024

Stress-Induced Oxytocin Reactivity As A Predictor Of Daily Support Seeking After Stress, Cecile Sunahara

Psychology Theses and Dissertations

The current study examined whether stress-induced peripheral oxytocin (OT) was associated with support-seeking behaviors after stress in daily life. Healthy male and female participants (N=94) performed a standardized laboratory stressor, the Trier Social Stress Test (TSST), and then completed two weeks of daily assessments of support seeking after stress. In line with preregistered hypotheses, plasma OT reactivity to the TSST (indexed as the area under the curve with respect to increase; AUCi) was associated with more frequent support seeking behaviors following stress in daily life. Moreover, this association was stronger for individuals with higher levels of attachment anxiety, relative to …


Strength In A Pinch: Sex Differences In Detection Of And Responses To Threats, Lorena Mesquita Ragonesi Jan 2024

Strength In A Pinch: Sex Differences In Detection Of And Responses To Threats, Lorena Mesquita Ragonesi

Honors Theses

Handgrip strength is a sexually dimorphic marker of muscle activation and force production. Males consistently demonstrate greater baseline maximal handgrip strength than females. Various factors can influence an individual’s handgrip strength; interestingly, threat detection can increase handgrip strength. Recently, Kawakami et al. (2018) reported that mortality salience increases handgrip strength in men, but not in women. To explain this finding, they argued that physical strength is a more salient goal for men than women, whereas women should strive for beauty as a strategy to avoid harm. While they did find this interesting sex difference in their study, we had concerns …


You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler Sep 2023

You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler

Dissertations, Theses, and Capstone Projects

Humans have a fundamental need to form and maintain social connections, and thus experiencing social exclusion is extremely distressing as it threatens this basic human need. Individuals who are socially excluded often respond aggressively, not only towards their ostracizers but also towards innocent bystanders, with ostracism being implicated in extreme acts of violence such as school shootings. However, individual differences in behavior exist within the context of social exclusion as not everyone responds aggressively after being ostracized. Identifying risk factors for retaliatory aggressive behavior following experiences of social exclusion may facilitate the development of targeted interventions aimed at mitigating such …


Self-Confidence And Hormonal Contraceptive Use, Abigail Doran May 2023

Self-Confidence And Hormonal Contraceptive Use, Abigail Doran

Biological Sciences Undergraduate Honors Theses

Hormonal contraceptives are widely used to regulate menstrual cycles, alleviate certain symptoms linked to reproductive hormones, and prevent pregnancy. However, women who take hormonal contraceptives may experience significant physical and psychological side effects such as increased rates of depression and changes in self-image. The current study examined self-confidence in women before beginning hormonal contraceptives and two months after using them. These participants were compared to a control group of naturally cycling women who were also assessed twice. I hypothesized that women would experience decreased feelings of self-confidence in several domains of their lives, compared to the naturally cycling women. Results …


The Project That Claire, Uh I Mean The Student Completed: Relative Clauses And Repair Disfluencies, Claire O’Shaughnessy Apr 2023

The Project That Claire, Uh I Mean The Student Completed: Relative Clauses And Repair Disfluencies, Claire O’Shaughnessy

Honors Theses

Several areas of psycholinguistics focus on the role of memory in language processing. Two of these areas are repair disfluencies and complex syntactic structures; however, these two topics have traditionally been investigated completely separately from one another. The current experiment combines these two topics by presenting listeners with spoken sentences containing subject-extracted relative clauses (SRCs) and object-extracted relative clauses (ORCs) in which the semantic similarity between the critical noun phrases (NPs) was manipulated. In addition, the sentences could be spoken fluently, or there could be a repair disfluency in which the reparandum contained information that would be potentially helpful in …


The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig Sep 2022

The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig

Dissertations, Theses, and Capstone Projects

Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …


Utilization Of The Fundamental Attribution Error With Increased Immune System Inflammation, John Odom May 2022

Utilization Of The Fundamental Attribution Error With Increased Immune System Inflammation, John Odom

Biological Sciences Undergraduate Honors Theses

Immune system inflammation is associated with sickness behavior, depressive mood, and alteration of decision-making processes. Because of these cognitive effects, inflammation may also lead to increased use of heuristics, for example the Fundamental Attribution Error (FAE). In the current research, inflammation was experimentally increased using the influenza vaccine, with participants receiving either the vaccine or a placebo injection and completing a measure that tests for the FAE. There were no significant differences between the two conditions regarding the number of personal, situational, or overall attributions made by the participants in the measure that would indicate use of the FAE. However, …


Borderline Personality Symptoms And Relationship Threat: The Moderating Role Of Perceived Parental Rejection, Elsa Baumgartner Apr 2022

Borderline Personality Symptoms And Relationship Threat: The Moderating Role Of Perceived Parental Rejection, Elsa Baumgartner

Student Research Submissions

Individuals with borderline personality disorder (BPD) often perceive relationship threats more intensely, resulting in increased emotional reactivity. However, this link has never been examined with physiological measures in “real time,” nor have reports of perceived parental rejection ever been investigated as a potential moderator of this link. To fill this gap, the present study induced romantic relationship threat, after which participants completed an emotional reactivity task while electroencephalography data were recorded. Results reveal that higher levels of BPD features were associated with increased emotional reactivity, indicated by larger late positive potential (LPP) amplitudes, to negative stimuli in the face of …


Parent-Prompted Dysregulation: Do Parents Serve As Cues For Dysregulation In Some Children?, Daniel Lee Jan 2022

Parent-Prompted Dysregulation: Do Parents Serve As Cues For Dysregulation In Some Children?, Daniel Lee

Pitzer Senior Theses

Children occasionally encounter dysregulation when interacting with their parents in relatively neutral or positive scenarios. Given that the cause of dysregulation is usually relational, meaning it is often cued by someone who is seen to have power or control over the person, children could be particularly susceptible to dysregulation in the presence of their parents. However, when examining the existing literature, there appeared to be a lack of research and knowledge concerning this topic, with much of the literature focusing on the effect of child stressors on parental dysregulation. As a result, the term parent-prompted dysregulation was developed to refer …


Caution Fatigue: Group Identification And Disgust Provide Protection In The Covid-19 Pandemic, Logan F. Ashworth Jan 2021

Caution Fatigue: Group Identification And Disgust Provide Protection In The Covid-19 Pandemic, Logan F. Ashworth

Cal Poly Humboldt theses and projects

The current Coronavirus pandemic has yielded an abundance of concerns regarding the psychological effects of isolating a highly social species through widespread lockdowns and enhanced social distancing. Research show that many are suffering from mental health crises, while also refusing to isolate (Brooks et al., 2020; Czeiler, et al., 2020). These behaviors combine to increase risk of viral infection. An emerging term to explain this paradox is “Caution Fatigue”. Yet, there is no research that outlines its specific underlying mechanisms. The goal of this paper is to propose a series of models that delineate caution fatigue through the effects a) …


Social Comparison Tendencies And The Reward Value Of Same-Sex Beauty Among Heterosexual Women, Melissa M. Martin Ms. Jan 2021

Social Comparison Tendencies And The Reward Value Of Same-Sex Beauty Among Heterosexual Women, Melissa M. Martin Ms.

Cal Poly Humboldt theses and projects

Previous studies have suggested that heterosexual women, but not heterosexual men, find same sex beauty rewarding. This finding has been attributed to a “greater bisexual interest among heterosexual women”, but no other explanations have been offered or tested. The current study aimed to explore social comparison tendencies as a potential alternate explanation to this previously observed finding. Twenty-three heterosexual women completed a series of questionnaires designed to assess their social comparison tendencies (the social comparison orientation scale, the physical appearance comparison scale, and the intrasexual competition scale). They also completed a “pay-per-view” keypress task to measure the reward value of …


Does Testosterone Affect Sexist Attitudes In Men? A Simulated Analysis, Steven R. Bowman Jan 2020

Does Testosterone Affect Sexist Attitudes In Men? A Simulated Analysis, Steven R. Bowman

Cal Poly Humboldt theses and projects

Sexism continues to negatively affect the lives of women across many cultures and modern societies. Although sexism has a damaging effect on people overall, women are disproportionately affected. Previous research on the topic generally explores attitudes, culture, socioeconomic status, sexual and violent crime census data, and developmental factors, but there is a lack of research investigating potential links among biological factors, such as hormone levels, and sexist attitudes. The present study used simulated data to simulate a study investigating the relationship between endogenous testosterone, cognitive aggression, and sexist attitudes. Using the faux, pwr2ppl, and ProcessR packages in R Studio open-source …


Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan Sep 2019

Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan

Dissertations, Theses, and Capstone Projects

Psychopathy is a multifaceted disorder characterized by a lack of cognitive and emotional empathy. The traditional model of psychopathy divides the disorder into two factors: Factor 1 consists of the interpersonal and affective traits of psychopathy while Factor 2 measures antisocial behaviors and lifestyle choices. The attention-to-the-eyes hypothesis argues that psychopathic individuals have impaired emotion recognition (specifically for fear) due to deficits in orienting attention to salient facial features like the eyes. Psychopathic individuals also display blunted autonomic responding to emotional stimuli, though whether this is due to attention-orienting deficits remains to be clarified. The present project investigated whether empathy-related …


Emotion Identification And Beliefs About Emotions As Mediators Of Ptsd And Parenting Meta-Emotion Philosophies, Maegan Calvert Aug 2019

Emotion Identification And Beliefs About Emotions As Mediators Of Ptsd And Parenting Meta-Emotion Philosophies, Maegan Calvert

Graduate Theses and Dissertations

Approximately 20% of women are sexually victimized and incarcerated women’s rates of victimization are much higher. In addition, women have a higher rate of PTSD and trauma-related sequelae than men. Interpersonal trauma experiences can have a negative impact on emotional processes such as alexithymia, recognizing others’ emotions, and healthy beliefs about emotional experiences. These difficulties are associated with problematic parenting. However, the mediational processes by which PTSD and disruptive emotional processes affect parenting is unclear. The current study examines the associations among PTSD, alexithymia, negative beliefs about emotions, emotion recognition in children, and parenting meta-emotion philosophies in incarcerated women presenting …


Team Member Hormone Profiles And Group Cohesion, David Webster Jan 2019

Team Member Hormone Profiles And Group Cohesion, David Webster

Theses and Dissertations (Comprehensive)

Group cohesion in sport is associated with many positive outcomes for the team as a whole, as well as for the individuals. Hence, it is important to understand the antecedents of cohesion in various contexts, including sport. One antecedent that has yet to be examined in a sports context pertains to biological factors; specifically, the interaction of testosterone and cortisol levels. The dual-hormone hypothesis posits that testosterone levels are associated with status attainment for both individuals and groups, but only amongst those with low cortisol levels. Based on previous literature, a high testosterone-low cortisol hormonal profile should be associated with …


Dispositional Empathy And Autonomic Reactivity During A Comfort Interaction, Alaina G. Tiani Jan 2019

Dispositional Empathy And Autonomic Reactivity During A Comfort Interaction, Alaina G. Tiani

Graduate Theses, Dissertations, and Problem Reports

The purpose of the current study was to examine the association between dispositional (trait) empathy and autonomic reactivity during dyadic interactions among women enrolled in undergraduate psychology courses. The primary research question was: do individuals who are deemed higher in dispositional empathy according to self-report exhibit differential autonomic reactivity patterns during a task in which they are asked to comfort another student experiencing emotional distress than those who are deemed lower in dispositional empathy? The literature on this relation has been mixed and has utilized photos or videos to evoke emotion; thus this study sought to examine the relation between …


"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 …


Wellness And Karate, Cristina Kumpf Aug 2018

Wellness And Karate, Cristina Kumpf

Electronic Theses and Dissertations

The promotion of wellness is an integral part of the counseling field and is considered to be a central focus to the counseling process (Barden, Conley, & Young, 2015; Myers, 1992). The counseling profession adopted the concept of wellness because it harmonizes with many of the founding principles of the ACA and is seen as a process of questing toward optimal health and well-being in body, mind, and spirit (Barden, Conley, & Young, 2015; Myers, 1992; Myers, Sweeney, & Witmer, 2000). Additionally, ACA Code of Ethics (2014) state that counselors “engage in self-care activities to maintain and promote their own …


The Immediate And Long-Lasting Cognitive Consequences Of Adolescent Chronic Sleep Restriction, Kerry Howard May 2018

The Immediate And Long-Lasting Cognitive Consequences Of Adolescent Chronic Sleep Restriction, Kerry Howard

Seton Hall University Dissertations and Theses (ETDs)

Adolescence is a critical developmental period. An important change that occurs in adolescence is the neurological maturation for adult-type cognitive abilities. Research has linked adequate sleep quantity to successful learning and memory capabilities. However, due to a shift in sleep timing drive in adolescence, in combination with early awakening for school, the adolescent population is experiencing chronic sleep restriction (CSR). What repercussions to long-term memory capabilities could CSR in adolescence have immediately and are the consequences long-lasting? The present study modeled human adolescent CSR in rats through four hours of sleep deprivation for five days, followed by two days of …

The purpose of this study is to assess patients’ behavioral, cognitive and social/environmental factors as it relates to their commitment to sobriety and examine how the involvement of family members influences the patient’s recovery process. I utilized a mixed methodology of quantitative and qualitative interviews of patients and family members. The findings suggest depressive symptoms were negatively correlated with …


Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton May 2018

Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton

Honors Projects

A literature review discusses yoga and health involving oxytocin creates the premise for a proposal combining the knowledge of yoga and its health benefits along with oxytocin's potential involvement during group exercise, yoga specifically. The proposed study's results of oxytocin measures and questionnaires have the potential to develop an understanding of the possible impacts of yoga on mood, particularly relationships between group exercise and yoga, which may help develop forms of group exercise or implement group yoga to assist or replace treatment for stress-caused or stress-related disorders.


Using Functional Infrared Thermal Imaging To Measure Stress Responses, Julia Tenaya Kandus Jan 2018

Using Functional Infrared Thermal Imaging To Measure Stress Responses, Julia Tenaya Kandus

Cal Poly Humboldt theses and projects

The stress response reflects a coordinated pattern of physiological changes that serves the adaptive function of increasing an organism’s ability to cope with situations that require action or defense. The changes in blood flow associated with the stress response may be detectable using the relatively new research technique of functional infrared thermal imaging (fITI). The present study was designed to determine the time-course and topography of temperature changes in human faces during the experience of a stressor. Infrared images were taken from 29 female participants while they completed the mental arithmetic component of the Trier Social Stress Test (TSST). Continuously …


Do Flashbulb Memories Transmit Across Generations? 9/11 As A Case Study, Shanique Meyler Dec 2017

Do Flashbulb Memories Transmit Across Generations? 9/11 As A Case Study, Shanique Meyler

Student Theses

Psychologists have only recently begun to examine the extent to which personal memories transmit across generations. When they have, they typically focus on family stories (see Merrill & Fivush, 2016) or memories of historical events (Svob & Brown, 2012). The present study extends this line of research to flashbulb memories, or memories of an individual’s circumstances when first learning about a consequential, historical event (Brown & Kulik, 1977). To this end, the present study examines the extent to which flashbulb memories surrounding the events of the terrorist attacks on 9/11 transmit to the next generation. The results suggest that flashbulb …


Mediators And Moderators Of Childhood Family Adversity And Adult Cortisol Response: The Role Of Marital Conflict Behavior, Jeffrey P. Winer Nov 2017

Mediators And Moderators Of Childhood Family Adversity And Adult Cortisol Response: The Role Of Marital Conflict Behavior, Jeffrey P. Winer

Doctoral Dissertations

Childhood family adversity influences behavioral and physiological response processes to acute interpersonal stress. Additionally, conflict behaviors in marriage are primary determinants of stress response and related psychological problems in adulthood. As little research has examined these two important literatures simultaneously, further work is warranted to clarify the role of marital conflict behavior in the relation between childhood family adversity and adult cortisol response to conflict. The current study examined relations between childhood family adversity, observed marital conflict behaviors, and salivary cortisol in response to acute marital conflict among 228 different-sex newlywed couples. We examined intrapersonal “actor” effects as candidate mediators …


The Effects Of Predictability On Stereotypic Behavior In Nonclinical Adult Humans (Homo Sapiens) And Rhesus Macaques (Macaca Mulatta), Amy Ryan Jul 2017

The Effects Of Predictability On Stereotypic Behavior In Nonclinical Adult Humans (Homo Sapiens) And Rhesus Macaques (Macaca Mulatta), Amy Ryan

Doctoral Dissertations

Stereotypies, or repetitive and purposeless behaviors, are observed in both humans and other animals. They have been primarily studied in captive animal and clinical human populations with comparably little research devoted to understanding less severe levels of stereotypies observed in nonclinical populations of adult humans and in most captive animals. As these behaviors are sometimes associated with routine events, I explored the relationship between the predictability of anticipated events and mild stereotypies. I studied this relationship in captive rhesus macaques and a novel comparison group of adult humans from a nonclinical population. I designed two experimental paradigms, a wait paradigm …


Psychopathy And The Effect Of Imitation On Empathetic Pain, Emily N. Lasko Jan 2017

Psychopathy And The Effect Of Imitation On Empathetic Pain, Emily N. Lasko

Electronic Theses and Dissertations

Psychopathy is a disorder largely characterized by a marked deficit in empathy, however, the specificity and extent of the deficit is currently unclear. While it has been well-established in the literature that individuals higher in psychopathy tend to have intact Theory of Mind abilities and exhibit a deficient ability for affective empathy (Blair, 2005), the contribution of motor empathy to these abilities, particularly in regard to empathy for pain, has yet to be experimentally examined. Additionally, the possibility of imitation increasing motor empathic abilities has not been tested in this capacity. The goal of the current study was to further …


Differentiating The Effects Of Animal-Assisted Versus Equine Facilitated Psychotherapy On Positive Psychological Outcomes Through A Stress Induction Context, Catherine J.V. Jones Jan 2017

Differentiating The Effects Of Animal-Assisted Versus Equine Facilitated Psychotherapy On Positive Psychological Outcomes Through A Stress Induction Context, Catherine J.V. Jones

Electronic Theses and Dissertations

The unique benefits of Equine Facilitated Psychotherapy (EFP) such as the human-horse bond, a non-traditional therapy setting, and performing altruistic acts are thought to facilitate positive change in humans. One mechanism by which positive changes occur is through improved coping and resilience in the face of stress. To date, only a handful of correlational studies speak to the potential effects of EFP on resilience-based outcomes. Thus, this study sought to address this gap in the literature by exploring the benefits of EFP compared to traditional Animal Assisted Therapy (AAT) in an experimental context. Specifically, we examined the effects of different …


Alleged Insanity: Frank Johnson Sr., Racial Injustice, And The Failure Of The Mental Health Care System In South Carolina, Jonathon P. Johnson Oct 2016

Alleged Insanity: Frank Johnson Sr., Racial Injustice, And The Failure Of The Mental Health Care System In South Carolina, Jonathon P. Johnson

Senior Theses

This thesis is about Frank Johnson Sr. and the circumstances that led to his downfall as a farmer and father of six, to his tragic death in the isolation of a racially segregated mental institution 18 miles away from his home. Using his life and incarceration at the South Carolina State Park mental health facility, I argue that racial injustice contributed to his tragic death and the woefully inadequate treatment thousands of African Americans in South Carolina received during Jim Crow. Additionally, I argue that the tragic circumstances around my great grandfather’s institutionalization and death were part of an enduring …


Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot Sep 2016

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …


The Effect Of Descriptive Norms On Resistance Exercise Self-Efficacy In College-Aged Females 2016, Justin Kompf May 2016

The Effect Of Descriptive Norms On Resistance Exercise Self-Efficacy In College-Aged Females 2016, Justin Kompf

Master's Theses

Resistance training is a form of physical activity that provides substantial health benefits. Despite these widespread benefits, participation in resistance training is considerably low, particularly among females. To engage in a skill-related activity such as resistance training, individuals need to have confidence in their abilities. Self-efficacy is a cognitive construct that is used to describe situation-specific self-confidence. Descriptive norms are a type of social norm that describes the behavior of others. Descriptive norms have been useful in positively changing health related behaviors. The exact mechanism of how descriptive norms alter behavior is unknown. However, it has been show in research …
