The Study Of The Potential For Positive And Negative Color Connotation Through Associations, Jamesa Mecayla Gray

Undergraduate Honors Theses

This project explored word associations with colors and shades of colors in a controlled manner to test the hypothesis that people associate negative descriptor and emotion words with darker shades and colors and positive descriptor and emotion words with lighter shades and colors. Two parts were completed. In the first, participants saw 8 colors in 3 different shades for a total of 24 colors presented, one at a time. In a first round of trials, participants were instructed to give the first three words that came to mind when they saw each color. In a second set of trials, participants …

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 …

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 …

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 …

Effect Of Instruction Language On English-Spanish Bilinguals' Speech Perception, Alexa Andrade

Undergraduate Honors Theses

Throughout the years, researchers have investigated the various advantages that may exist of being bilingual; however, it is unknown how switching between languages affects a person’s basic perception of speech sounds. The goal of this thesis was to determine whether Spanish-English bilinguals respond to auditory stimuli differently based on the language in which they receive task instructions. Participants were randomly assigned to receive instructions and complete the study entirely in English or Spanish, thus thinking in the language that they were assigned. In the study, participants listened to three different sets of recordings, which could be perceived as a word …

Do You Salt Your Soup: Investigating The Effect Of Interference Control On The Cognitive Reflection Test, Matthew Lowrie

Undergraduate Honors Theses

The present study seeks to examine the role of interference control in solving the Cognitive Reflection Test (Frederick, 2005). Participants were given the CRT, CRT-2, and completed a novel adaptation of the Stop-Signal Task called the Change-Signal Task. The Change-Signal Task is similar to a stop-signal paradigm except that the participant must switch their response when a change-signal is present in the Change-Signal Task instead of withholding a response. This study found that interference control as assessed by the Change-Signal Task was important for determining performance on the CRT-2 but not for the CRT. Implications of these findings and interpretations …

The Cognitive & Educational Implications Of Color Use In Drawing To Learn, Juliana F.M. Cantarutti

Undergraduate Honors Theses

Drawing to Learn (D2L) is a learning aid that encourages STEM students to interact with abstract concepts in STEM by sketching. D2L is not an intuitive skill, and researchers strive to provide students with guidelines on how to master this method. One potential way to enhance the D2L method for students is by incorporation of visual cues, specifically color. While many students choose to incorporate color into their models without explicit instruction to do so, we have found no research on: a) why students use color in sketching, b) its effects on D2L. This study used interviews, surveys, and course …

Optimizing Music Learning: The Effects Of Contextual Interference On Memorization, Carmen Andrea Wong

Undergraduate Honors Theses

The purpose of this study was to assess if blocked or interleaved practice learning was more effective for memorizing music, and to assess if metacognitive judgements aligned with performance. The study included 21 proficient pianists who regularly engage in piano practice. Participants learnt two excerpts and two technical studies, and played them from memory on both day 1 and day 2 of testing. Performances were recorded and rated by an expert in the field on a percentage scale. A two-way repeated measures ANOVA analysis revealed no significant main effect of day on practice schedule, (F(1,20) = .15, p = 0.70, …

The Theory Of Mind Hypothesis Of Autism, Kendall Smith

Undergraduate Honors Theses

Present theory of mind research suggests that autistic individuals demonstrate deficits in theory of mind capabilities. A literature review was conducted to investigate the claim made by the theory of mind hypothesis of autism that theory of mind deficits are responsible for the social deficits present in autistic individuals. It was concluded that this hypothesis was prematurely accepted as an explanatory model for autism when it is better described as a symptom of autism. Alternative explanations for autistic social deficits such as executive function deficits and the theory of weak central coherence were analyzed. Implications and suggestions for future research …

Indicators Of Deception: Science Or Non-Science, Kristina Vasquez

Undergraduate Honors Theses

Deception detection is used by many law enforcement professionals who work in interviews and interrogations. The ability to detect deception or having knowledge on the signs of deception is very important in not only law enforcement, but in other careers and everyday life. The question remains: is deception detection a science or not a science? There are three areas where someone can learn how to detect deception and those are verbal communication, non-verbal communication, and paralanguage. The use of verbal communication looks at what the person is saying with their words. The use of non-verbal communication looks at what someone …

Reported Motivations For Non-Medical Use Of Prescription Stimulants In A Sample Of Community College Students, Taylor Wexler

Undergraduate Honors Theses

Introduction. Prior research has found high rates of behavioral health concerns, including several forms of substance use, among community college students. However, the prevalence of non-medical use of prescription stimulants (NMUS) as well as the motivations driving NMUS among community college students is unknown. Methods. Survey results from 13 community colleges within the Tennessee Board of Regents school system were evaluated to explore 1) rates of NMUS, 2) reported motivations for NMUS, and 3) how demographic characteristics including race, age, and income differ based on self-reported reasons for NMUS. Results. NMUS was reported by approximately 9% of the overall sample. …

Memory Suppression: The Importance Of Baseline Learning For The Think/No-Think Task, Curtis Rogers

Undergraduate Honors Theses

Studies using the think/no-think task have never addressed the baselines they use throughout the experiment. This study's primary goal was to investigate the effect differing baselines for word-pair learning (50% vs. 75%) would have on the think/no-think task. A replication of Anderson and Greene’s 2001 study using the Think/No-Think task was performed using either a 50% or 75% baseline as a threshold for participants moving to the think/no-think phase of the experiment. Due to the COVID-19 pandemic, this study implemented the think/no-think task online. Recall was evaluated using same and independent-probe memory tests.

Firstly, this study replicated the think/no-think effect …

The Effects Of Verbalizable Features On Category Learning Strategies, Marwan A. Syed

Undergraduate Honors Theses

The present study investigated the effects of how verbalizable features (easy vs not-easily) are on category learning strategies with respect to the COVIS model, which states there are two competing systems (verbal and implicit) that operate simultaneously when making categorization decisions. A total of 102 undergraduate students took part in the experiment, which was an A-B categorization task conducted in a video game setting. A rule-based approach reflected the verbal system whereas a family resemblance approach reflected the implicit system. The findings partially support the hypothesis and COVIS model in that participants in the easily verbalizable condition were more likely …

Formation Of Implicit Memories From A Narrative Played During Sleep, Amanat Ludhar

Undergraduate Honors Theses

Though, it was previously thought that the sleeping brain was dormant, research suggests that participants can process salient stimuli and form implicit memories of simple stimuli (e.g. words) during sleep. Thus, the current study aimed to determine whether participants could form implicit memories of a narrative played during sleep, and what role different sleep stages played in this memory formation. Participants were played a story while taking a nap, and EEG was used to track time spent in different sleep stages. Later, participants completed an implicit memory task where they were asked to differentiate between animal and non-animal words through …

Does Psychological Resilience Affect The Relationship Between Adverse Childhood Experience And Self-Regulation?, Jiacheng Yu

Undergraduate Honors Theses

The present study investigated the potential effect of psychological resilience on the relationship between adverse childhood experience (ACEs) and self-regulation. There were 18 adult participants (five males and 13 females). The ages ranged from 19 to 30 (M = 23.11, SD = 3.39) years old. To measure psychological resilience, ACEs, and self-regulation, participants were required to respectively finish the Connor-Davidson Resilience Scale, the Adverse Childhood Experience Questionnaire, and the Two-Urn Task. Contrary to expectation, data analysis showed that the negative correlation between ACEs and self-regulation remained statistically significant regardless of the resilience level, suggesting that resilience did not alleviate …

Comparing Executive Functions In Dancers Versus Aerobic Exercisers: A Study On Older Adults, Jai S. Ravipati

Undergraduate Honors Theses

Many older adults may experience cognitive decline with aging, and with a rising aging population it is important to investigate interventions that improve cognitive functions. The purpose of this study was to assess differences in executive functioning between older adult dancers and older adult aerobic exercisers. Given that dance involves the use of executive functions, in addition to engaging in aerobic exercise, older adult dancers were expected to score higher on the executive functioning tasks than the older adult aerobic exercisers. Using the Cambridge Brain Sciences Battery to assess executive functioning, this study sought to compare older adults, 50 years …

Investigating The Eeg Error-Related Negativity In College Students With Adhd, Anxiety, And Depression, Mariacristina Canini

Undergraduate Honors Theses

Error-related negativity (ERN) is an event-related potential elicited by the commission of errors. It appears as a negative deflection peaking between 50ms and 100ms after an erroneous response. Previous literature demonstrated that individuals who suffer from either anxiety or depression display a higher ERN amplitude compared to a control group. It has also been shown that people with ADHD display a lower ERN amplitude. Based on these findings, we investigated the relationships between these three disorders and their effects on the amplitude of the ERN. We recruited thirty-one students at East Tennessee State University and gathered data on their level …

Childhood Development: How The Fine And Performing Arts Enhance Neurological, Social, And Academic Traits, Katherine Rowe

Undergraduate Honors Theses

Abstract

Childhood development has always been a major topic when studying psychology and biology. This makes sense because the brain develops from the time a child is conceived to the time that child has reached around the age of twenty-seven. Doctors, psychologists, and sociologists look at numerous things when studying childhood development. However, how common is it for researchers to study how the fine and performing arts affect childhood development? Sociologists tend to be extremely open and mindful of all aspects of things such as culture, sexuality, religion, and even age. By taking a sociological standpoint when studying the arts …

Transcranial Magnetic Stimulation To Assess Motor System Excitability Fluctuations During Auditory Anticipation And Beat Perception, Johannes G.P Teselink

Undergraduate Honors Theses

Humans tend to spontaneously move to the regular beat of musical rhythm. Beat perception is the tendency to sense and anticipate the regular time positions (beats) that movements synchronize with. The neural motor system plays an important role in beat perception, but the dynamics of excitability in the motor system associated with beat perception have not been characterized. This project investigated motor system excitability fluctuations using transcranial magnetic stimulation and electromyography during perception of beat-based and non-beat-based rhythms. We applied single-pulse TMS over the left primary motor cortex of healthy participants as they listened to three types of rhythms that …

Correlation Between Automatic Processing Of Symbolic And Non-Symbolic Magnitudes In Children, Jake M B Kaufman

Undergraduate Honors Theses

Does the automatic activation of number influence children’s decision-making on physical size judgments? Previous work dealing with how children process symbolic and non-symbolic numbers typically involves making direct judgments about numerical values. In this study, instead of asking for judgments about numerical magnitude, we assessed the automatic activation of number by asking children to make physical size judgments. This will allow us to further learn how children use their understanding of numbers to help them make decisions that do not directly involve numbers. In addition to this, by looking at how the processing of symbolic and non-symbolic numbers relate, we …

Hope Is A 4-Legged Word: How Service Dogs Can Help Veterans Suffering From Combat-Related Post Traumatic Stress Disorder, Holly Katherine Robinson

Undergraduate Honors Theses

As the rate of posttraumatic stress disorder (PTSD) continues to increase among our veterans returning from the War on Terror, the need for alternative treatment options is becoming more critical. One such alternative is the use of psychiatric service dogs specially trained to assist those living with PTSD. However, little empirical research has been conducted to support the legitimacy of this treatment option. This present study sought to explore the benefits that could be gained from the use of a service dog to treat PTSD by exploring relevant literature. The training the dogs receive as well as the possible problems …

The Effects Of Deception And Manipulation Of Motivation To Deceive On Event Related Potentials, Ethan C. Ashworth

Undergraduate Honors Theses

The Correct Response Negativity (CRN) is an event-related potential component that is affected by the act of deception. However, there have been inconsistent findings on the effect of deception on the CRN. Suchotzki, et al. (2015) suggested that the design of the paradigm used to elicit the deceptive response is what controls the size of the CRN. Specifically, motivation to deceive changes the size of deception relative to telling the truth. This study attempted to follow up on suggestions made by Suchotzki et al. (2015) to investigate if extraneous motivation to lie does indeed invert the ratio of CRN in …

The Mental Number Line In Domestic Chicks, Samantha Noyek

Undergraduate Honors Theses

The estimation of number by humans shows evidence for a mental number line in which magnitude increases from left to right. Rugani, Vallortigara, Priftis, and Regolin (2015) recently reported a similar mental number line in domestic chicks. This is an unexpected result given the role of language and culture in the human mental number line. Animals do not possess language or arithmetic concepts like the mental number line. Because the results reported by Rugani et al. (2015) seem improbable from this perspective, my study sought to determine whether the observations of Rugani et al. (2015) occur reliably. I tested for …

Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber

Undergraduate Honors Theses

Relatively few studies have investigated the relationship between executive functioning (EF) and language development, and even fewer have researched hot and cool EF as a predictor language development. This study is an investigation into the relationship between EF and language development in preschool aged children. More specifically, the ability for hot or cool EF to predict language, this will be the focus of the study. It was found that hot EF was a better predictor of language development in preschool aged children.

Empirical Validation Of An Executive Function Battery For Use In Childhood And Adolescence, Emma K. Phillips

Undergraduate Honors Theses

This research explores the reliability and efficacy of a child and adolescent adaptation of an adult battery of executive functioning, measuring the constructs of reasoning, short-term memory and verbal processing. The intent of the research is twofold as it intends to support an age appropriate adjustment of a battery of tasks presented by Hampshire, Highfield, Parkin and Owen (2012), and secondly to display the necessity of looking at executive functions as multifaceted and therefore requiring multiple tasks to encompass their complexities. The adjusted battery in analysis is composed of nine tasks that have been amended to be age appropriate for …

The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn

Undergraduate Honors Theses

The presence of music is a visceral part of the human experience and its influence on cognitive function is a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of mood and arousal and their influence on attention, thus the purpose of this study. Fifty undergraduate students currently enrolled at the University of Western Ontario were recruited for this study. Given that music is a highly subjective experience, participants rated an assortment of music clips on …

The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar

Undergraduate Honors Theses

The present study investigated the interaction between working and reference spatial memory in an effort to develop an animal model of this interaction. Twelve male Long-Evans rats were tested on an eight-arm radial maze in a two-phase procedure. In the study phase, a rat was allowed to enter four randomly selected arms for a food reward placed at the end of each arm. The test phase allowed the rat access to all eight arms, but only the previously unentered arms contained food. Two of the correct test arms were defined as reference memory arms because they were always correct. The …

Punchline Predictability, Comprehension Speed, And Joke Funniness: Investigating Incongruity Theories Of Humour, Robert J. Fearman

Undergraduate Honors Theses

Surprise is an important element of many cognitive theories of humour (e.g., Suls, 1972): the less predictable the punchline, the funnier a joke is expected to be. Many theories also predict a curvilinear relationship between speed of joke comprehension and funniness: jokes that are too easy or too difficult should be less funny than those that require an intermediate amount of processing. This study was designed to investigate these two assumptions of past theories. Undergraduate psychology students (N = 183) participated online and completed two tasks. The Joke Completion Task required the participants to read the joke stem of …

Selecting And Striving For Goals, Angela Allan

Undergraduate Honors Theses

Mental Contrasting (MC) is a self-regulating strategy in which one identifies a goal, visualizes a positive outcome, and then considers a current personal obstacle to that goal. Agency thinking signals an individual’s confidence in her ability to execute the necessary goal-directed behaviours (Snyder, 2002). 99 university students selected an academic goal and conducted either a MC or control exercise. Subjects completed agency scales before and after treatment and goal commitment scales following treatment. How does Mental Contrasting impact students’ sense of agency and commitment toward an academic goal? It was hypothesized that goal commitment scores would be greater for the …
