Sleep And Early Childhood Stressors In College Students: Examining Alcohol Use As A Moderator, Sylvain N. Chassagneux

Undergraduate Honors Theses

Early childhood stressors (ECS) consist of certain emotional, physical, or sexual experiences that may have long term consequences including sleep problems. Previous research has also found that alcohol use can negatively affect sleep; however, few studies have investigated alcohol use as a moderator of the relationship between sleep and other variables. In the current study, we examined whether the relationship between a general measure of ECS and sleep in college students may be moderated by alcohol use, a common psychoactive substance among this age group. Additionally, we examined this model with emotional abuse and neglect as a measure of ECS. …

Associations Among Self-Regulation, Life Stress, And Suicidal Ideation In Adolescents: A Developmental Psychopathology Approach, Yifan Yuan

Undergraduate Honors Theses

Background: Suicide is a major public health concern among adolescents. Although research has made progress in identifying risk factors for youth suicidality, there has been less focus on early developmental antecedents of youth suicidal thoughts and behaviors. Taking a developmental psychopathology perspective, we examined longitudinal associations among multiple aspects of self-regulation (i.e., emotion regulation, emotion reactivity, parasympathetic regulation, inhibitory control), life stress, and suicidal ideation. We hypothesized that deficits in self-regulation during middle childhood and early adolescence and greater life stress during early and middle childhood would predict higher lifetime suicidal ideation reported in adolescence.

Method: Participants were adolescents ( …

Aggression In And Out Of The Surrounding Space, Marissa Incer

Undergraduate Honors Theses

Social isolation is a type of punishment used to address misbehavior in individuals, such as children with time-outs and prisoners in solitary confinement. It was thought to be an effective method for teaching good behavior or alleviating tense situations. However, this type of punishment may worsen the punished individual’s aggression depending on the environment of isolation. The current study was divided into two experiments. In the first experiment, participants were isolated in a small (2x2 feet) or large (6x6 feet) space to observe if the space alone affected their aggression. In the second experiment, a frustration-inducing task was given to …

Examining Measures Of Eeg As Biomarkers For Autism Spectrum Disorder, Shuhan Liang

Undergraduate Honors Theses

A central aim of this study was to determine whether there are consistent differences in a variety of ERPs and/or resting state measures of EEG between children diagnosed with ASD and psychiatric controls. Additionally, we aimed to determine whether any of those differences would generalize to the neural correlates of continuous measures of autistic tendencies in the general population. We classified EEG data into three categories: basic sensory responses, cognitive/perceptual ERPs, and resting state measures. Our study indicated that basic sensory responses and cognitive/perceptual event-related potentials (ERPs) did not differentiate autistic individuals from controls. For resting-state measures, the high gamma …

Cognitive Decline And Contact Sports: The Relationship Between P3 Amplitude And Sub-Concussive Head Impact, Elizabeth Kerman

Undergraduate Honors Theses

The present study sought to explore the effect of repetitive sub-concussive head impacts on the P3 event-related potential (ERP) amplitude and measures of movement kinematics. University students participating in collision, contact, and non-contact sports at the club and varsity level completed a cued visuomotor adaptation task. Results indicated that participants who estimated experiencing four or more sub-concussive head impacts per week display a significantly reduced P3 amplitude across both normal and adaptive trials. Additionally, participants who estimated experiencing less than four sub-concussive head impacts per week displayed no significant changes in P300 amplitude between “switch” and “stay” trials. This research …

Investigating The Relationship Between N2pc And Rapid Saccadic Eye Movements, Kezhen Qi

Undergraduate Honors Theses

In this study, we investigated the impact of temporal variability on the N2pc component during overt and covert visual search tasks, with a focus on potential differences in the efficiency of search strategies. Employing an eye tracker and a modified algorithm for saccade detection, our analysis considered the potential influence of eye tracker performance and data cleaning methods on the interpretation of results. Additionally, we adopted ERPimage analysis to enhance the rigor of our statistical examination. Our findings confirmed the temporal relationship between the N2pc and first saccade onset, with the N2pc occurring after the saccade. Furthermore, we identified a …

The Superpower Of Sleep: Poor Sleep Quality Predicts Worse Executive Control Under Conditions Of Stress, Lilly M. Mcclendon

Undergraduate Honors Theses

Background: Over 60% of college students do not obtain the minimum recommended amount of sleep daily and over 54% experience above average levels of stress. Exposure to stress and poor sleep are each related to executive control, which is a set of cognitive abilities that are essential for daily functioning. Despite the prevalence of poor sleep and high stress, studies have rarely examined the joint impact of sleep and stress on executive control in students.

Objective: The purpose of this study was to examine whether the impairing effect of stress on executive control is stronger in individuals who obtain poor …

The Faces Of Substance Use: A Reverse Correlation Analysis Of Perceptions Of Alcohol And Cannabis Use, Madison Hallie Colby

Dissertations, Theses, and Masters Projects

Alcohol and cannabis are some of the most ubiquitous substances on college campuses. While the reason for use varies between each individual, from social lubricant to sleeping aid, nearly half of higher-education students endorse alcohol and/or cannabis use in the last month. Despite this popularity, there is still a deeply ingrained level of stigma around substance use and substance use disorders and people who use substances or struggle with substance use disorders are subject to a litany of damaging perceptions, such as being deemed violent, unpredictable, weak, and untrustworthy.. Most research on the stereotypic thinking surrounding substance use focuses on …

The Role Of Stereotype And Moral Values In Predicting Victim Blaming, Jihye Choi

Dissertations, Theses, and Masters Projects

Exposing participants to a victim with different racial identities (Asian American vs. African American vs. White American) under two different types of misfortunes (poverty vs. disease), the present study aimed to find whether the victim-blaming patterns differ depending on the victim’s race and whether the difference in victim-blaming tendency could be explained by the interaction between pre-existing stereotypes and situational relevance.

The Association Between Sociodemographic Risk, Parental Substance Use, And Child Emotion Regulation Capabilities, Lydia Fay Bierce

Dissertations, Theses, and Masters Projects

Emotion regulation, defined as the ability to modulate one’s emotional experiences in order to navigate social interactions successfully and attain goals, has been associated with social competence, adjustment, and resilience during early childhood and beyond. Family-level risk factors have been linked to differences in emerging emotion regulation skills, measured at both the behavioral and physiological level. The current study investigated two familial risk factors, sociodemographic risk and parental substance use, as predictors of toddlers’ emotion regulation. Participants were 117 parent-toddler dyads recruited across a range of sociodemographic risk. Dyads completed a structured series of parent-child interaction tasks, including a resting …
