Cannabis Use Frequency And Mood On Creativity, 2017 Humboldt State University
Cannabis Use Frequency And Mood On Creativity, Caitlin Clark
Cal Poly Humboldt theses and projects
This study examines the relationship between cannabis use (infrequent, moderate, and heavy use) and one’s mood (neutral, positive, and negative) on creativity. Folk ideas of creativity and the relationships between cannabis use and mood may not reflect the real relationship between these factors (e.g. regarding cannabis use, it is perceived to be linked with higher rates of creativity; regarding mood, negative states [i.e. tortured artist] are thought to fuel creativity). Although both cannabis use and mood have been found to influence creativity independently, the current study is unique in its aims to identify whether cannabis use and mood interact to …
Pathways Linking Clinician Demographics To Mental Health Diagnostic Accuracy: An International Perspective, 2017 Virginia Commonwealth University
Pathways Linking Clinician Demographics To Mental Health Diagnostic Accuracy: An International Perspective, Julia Brechbiel
Theses and Dissertations
Significant research efforts have focused on examining the effect of patient factors on providing diagnoses across clinical settings; however, the influence of clinician demographics have received less attention. This study aimed to understand the impact of nonclinical factors such as clinician characteristics and response time on diagnostic accuracy. The study used data from a WHO field study of the ICD-11 development (n = 1822) that required clinicians to diagnose two case vignettes. Clinicians’ slower response times had a significant positive impact on their rates of diagnostic accuracy. However, there was no evidence that clinicians’ demographic features were directly related to …
Concreteness, Frequency, And Bilingual Language Dominance: Implications For The Impact Of Context Availability In Explicit Memory, 2017 University of Texas at El Paso
Concreteness, Frequency, And Bilingual Language Dominance: Implications For The Impact Of Context Availability In Explicit Memory, Randolph Taylor
Open Access Theses & Dissertations
One explanation for why concrete words are better recalled than abstract words is systematic differences across these word types in the availability of context information. In contrast, explanations for the concrete word advantage in recognition memory do not consider a possible role for context availability. Like concrete words, low-frequency words and L2 words also demonstrate item recognition advantages over high-frequency words and L1 words, respectively. Although the theories explaining these advantages do not explicitly discuss context availability, the mechanisms described suggest that context availability may play a role. The present study examined the extent to which context availability can explain …
Usability Is Not Just Usability: Discovering The Strategies Used By Non-Experts In Making Usability Predictions, 2017 University of Kentucky
Usability Is Not Just Usability: Discovering The Strategies Used By Non-Experts In Making Usability Predictions, Michelle A. Sublette
Theses and Dissertations--Psychology
Much of the research on metacognition in human factors has focused on prescriptive, normative strategy training. That is, many researchers have concentrated their efforts on finding ways to improve system users’ prediction, planning, monitoring and evaluation strategies for tasks. However little research has focused on the strategies and heuristics users employ on their own to make usability predictions. Understanding usability prediction methods is critical because users’ predictions inform their expectations about whether they will make errors using a product, how much effort they will need to expend to be successful in using the product, whether they can perform two tasks …
An Investigation Of The Relations Between Stress And Prospective Memory, 2017 University of Montana, Missoula
An Investigation Of The Relations Between Stress And Prospective Memory, Brandon T. Stewart
Graduate Student Theses, Dissertations, & Professional Papers
Prospective memory (PM) is a future-oriented memory system that entails “remembering to remember” intentions, or to perform actions in the future. People spend significant portions of their day-to-day lives forming and acting on intentions, and the ability to successfully generate, retain, and complete these intentions has important implications for one’s daily functioning and quality of life. Another common human experience is stress, whether that be short-term, acute stress, or long-term, chronic stress. Despite the significance and ubiquity of both PM and stress, the research base documenting the relations between them is sparse. This topic area necessitates additional research to delineate …
That Note Sounds Wrong! Age-Related Effects In Processing Of Musical Expectation, 2017 Bucknell University
That Note Sounds Wrong! Age-Related Effects In Processing Of Musical Expectation, Andrea R. Halpern, Ioanna Zioga, Martin Shankleman, Job Lindsen, Marcus T. Pearce, Joydeep Bhattacharya
Faculty Journal Articles
Part of musical understanding and enjoyment stems from the ability to accurately predict what note (or one of a small set of notes) is likely to follow after hearing the first part of a melody. Selective violation of expectations can add to aesthetic response but radical or frequent violations are likely to be disliked or not comprehended. In this study we investigated whether a lifetime of exposure to music among untrained older adults would enhance their reaction to unexpected endings of unfamiliar melodies. Older and younger adults listened to melodies that had expected or unexpected ending notes, according to Western …
Eeg Study Of The Featural And Configural Components Of Face Perception, 2017 University of Puget Sound
Eeg Study Of The Featural And Configural Components Of Face Perception, Heather Rose Stegman
Summer Research
Prior research using functional magnetic resonance imaging (fMRI) suggests that facial features (i.e. eyes, nose, and mouth) and their configuration (i.e. T-shaped arrangement of features) are processed in different face-specific brain regions. However, precise response time of featural and configural face processing is unknown. Featural processing may occur before configural processing, or configural processing may occur before featural processing; conversely, they may occur simultaneously. Here, using the electroencephalography (EEG), we will examine the face-specific event related potential (ERP), the N170, to analyze temporal differences between featural and configural face processing.
The Relationship Between Childhood Maltreatment And Sexual Coercion Proclivity In Women, 2017 Walden University
The Relationship Between Childhood Maltreatment And Sexual Coercion Proclivity In Women, Christina Renee Dean
Walden Dissertations and Doctoral Studies
Researchers have explored the effects of sociocultural factors on male and female sexual expression, as well as the relationship between sexual objectification and overall sexual well-being; however, few scholars have focused on how, when combined with early experiences of childhood maltreatment, such factors can result in increased long-term risks for a variety of concerns that may impede the development of healthy relationships in women. This quantitative study explores the relationship of childhood maltreatment and sexual coercion proclivity in adult women. The purpose of this study was to measure self-reports of 1 or more experiences with childhood maltreatment (i.e., physical, sexual, …
The Experience Of Forgiveness In Adults With Different Sacred Belief Systems, 2017 Walden University
The Experience Of Forgiveness In Adults With Different Sacred Belief Systems, Christy Jo Heacock
Walden Dissertations and Doctoral Studies
Forgiveness is the act of moving beyond shame, guilt, anger, or blame, and it has been linked to psychological well-being, prosocial behavior, and religion/spirituality (R/S). However, the research on why and how people forgive is inconsistent, as the concepts involved are complex and difficult to define and operationalize. The purpose of this interpretative phenomenological analysis (IPA) was to provide a better understanding of why and how people are cognitively and emotionally able to forgive and the role of R/S in that process. Goal orientation and cognitive restructuring theories were used as frameworks for understanding the forgiveness experience. First-person, semistructured interviews …
Recidivism Rates Among Juveniles With Mental Illness, 2017 Walden University
Recidivism Rates Among Juveniles With Mental Illness, Kia Chevon Russell
Walden Dissertations and Doctoral Studies
Treating mental illness is imperative to help reduce criminal justice involvement within the juvenile population. Receiving mental health care will help decrease the likelihood for youth to reoffend, ultimately reducing recidivism rates. Past studies showed there are risk factors associated with juveniles and recidivism; however, very few studies have examined what factors are prevalent after services have been received. The purpose of this study was to identify factors that increase the risk of recidivism among juveniles who have received psychiatric stabilization in Harris County, Texas. Risk factors that were assessed included age, gender, ethnicity, and criminal offense. The psychodynamic perspective …
The Relationship Between Coping Strategies And Burnout For Caregivers Of Adjudicated Youth, 2017 Walden University
The Relationship Between Coping Strategies And Burnout For Caregivers Of Adjudicated Youth, Debra Marie Dix
Walden Dissertations and Doctoral Studies
In the human services field little is known about the impact of coping strategies on the problem of burnout for primary caregivers of delinquent youth in placement. The purpose of this correlational research was to examine the relationship between coping strategies, youth psychopathology, and burnout. This study was based on Maslach's theory of burnout and Lazarus and Folkman's transactional model of stress and coping. To assess the prevalence of burnout and coping strategies, 82 primary caregivers of adjudicated youth in placement in the state of Michigan, completed self-report questionnaires: the Maslach Burnout Inventory, the Brief COPE Inventory, and the Child …
Ask A Busy Person? A Reexamination Of Cognitive Performance Under Load, 2017 Walden University
Ask A Busy Person? A Reexamination Of Cognitive Performance Under Load, Graham Watson
Walden Dissertations and Doctoral Studies
A longstanding folk belief suggests that 'busy' people possess the ability to get more done than others. Busyness, defined as the demands of everyday life, has been shown to generate cognitive load, which has been called 'cognitive busyness.' Although most cognitive theory would deny the possibility that cognitive load may enhance performance, some recent research may support the possibility. Cowan's 1988 information-processing model was used to study how measures of everyday busyness correlated with performance on cognitive tasks. The research question addressed whether any combination of such measures, in combination with working memory, could predict performance on such tasks. 92 …
The Relationship Between Schizotypy, Creativity, & Behavioral Inhibition, 2017 Murray State University
The Relationship Between Schizotypy, Creativity, & Behavioral Inhibition, Karrah Wood
Murray State Theses and Dissertations
A creative individual is believed to possess many positive traits—such as openness to new experiences and intelligence (Jauk, Benedek, & Neubauer, 2014)—but also traits that are considered less desirable, such as the tendency to be hostile or impulsive (Burch, Hemsley, Corr, & Gwyer, 2006; Fink et al., 2013). These findings reveal a possible link between creativity and psychopathology (Simonton, 1999). A large focus in the research has been on schizotypal personality disorder (i.e., “schizotypy”) and creativity, which has led to a number of positive findings between these two variables (Fink et al., 2013; Furnham, 2015). Additionally, other studies indicate that …
Musical Mnemonic Devices Or Method Of Loci: Which Promotes Higher Recall Of Concrete And Abstract Words?, 2017 Central Washington University
Musical Mnemonic Devices Or Method Of Loci: Which Promotes Higher Recall Of Concrete And Abstract Words?, Sky M. Corby
All Master's Theses
Mnemonic devices are excellent learning tools to aid in the recall of information. Literature has shown that musical mnemonic devices and the method of loci are two particularly useful mnemonic devices. The literature has also shown that there seems to be some discrepancy as to which one aids in the higher recall of information. This study investigated which learning device— musical mnemonic devices, the method of loci, or rote memorization— promotes a higher recollection of concrete or abstract words after immediate and 5 min recall tasks. The study consisted of 86 participants who were Central Washington University students, ages 18 …
Intertemporal Choice And Delayed Gratification, 2017 University of Nebraska-Lincoln
Intertemporal Choice And Delayed Gratification, Jeffrey R. Stevens
Jeffrey Stevens Publications
A parasitoid wasp has deposited half of her eggs in a host. She now faces the choice between depositing her remaining eggs in the same host or searching for another. Continuing to deposit in the current host provides the immediate payoff of completing her reproductive duties, allowing her to move on to other activities such as foraging or searching for another mate. Searching for another host, in contrast, delays the payoffs of reproducing until a suitable host is found. This wasp faces an intertemporal choice—that is, a choice between options that involve payoffs available at different times (Read, 2004; Stevens, …
Comparing Sexual Cognition And Risk By Gender, 2017 University of Central Florida
Comparing Sexual Cognition And Risk By Gender, Jacquelynne Dauk
Honors Undergraduate Theses
The ways in which sexuality is perceived among members of society has substantial effects in regards to overall health and well-being. The current study investigates not only the nature of sexual cognition but also the differences in cognition in regards to participant genders. More specifically, this study seeks to investigate the differences in sexual attitudes and thoughts among different genders that may lead to different forms of sexual risk. In order to identify these differences, societal influences such as social roles, parenting styles, and sexual education are all examined in regards to gender. Factors such as age and demographics were …
Real Loneliness And Artificial Companionship: Looking For Social Connections In Technology, 2017 University of Central Florida
Real Loneliness And Artificial Companionship: Looking For Social Connections In Technology, Fernando L. Montalvo
Honors Undergraduate Theses
Loneliness among older adults is a problem with severe consequences to individual health, quality of life, cognitive capacity, and life-expectancy. Although approaches towards improving the quality and quantity of social relationships are the prevailing model of therapy, older adults may not always be able to form these relationships due to either personality factors, decreased mobility, or isolation. Intelligent personal assistants (IPAs), virtual agents, and social robotics offer an opportunity for the development of technology that could potentially serve as social companions to older adults. The present study explored whether an IPA could potentially be used as a social companion to …
Testing Of Wrist-Worn-Fitness-Tracking Devices During Cognitive Stress: A Validation Study, 2017 University of Central Florida
Testing Of Wrist-Worn-Fitness-Tracking Devices During Cognitive Stress: A Validation Study, Nicole S. Chudy
Honors Undergraduate Theses
The intent of this thesis was to test if one of the many fitness-tracking devices, Microsoft’s Band 2 (MSB2), is accurate and reliable in detecting changes in Heart Rate (HR) and R-R intervals, during the repeated trial of two conditions of a working-memory test known as the N-Back. A 2 (devices: ECG, MSB2) × 4 (epochs: baseline 1, 1-back task, baseline 2, 3-back task) repeated measures factorial design was conducted. The participants were simultaneously equipped to the MSB2 and an electrocardiogram (ECG). The results of this study validated the MSB2 for the use in a cognitive task. The study suggests …
Human Classifier: Observers Can Deduce Task Solely From Eye Movements, 2017 University of Iowa
Human Classifier: Observers Can Deduce Task Solely From Eye Movements, Brett Bahle, Mark Mills, Michael Dodd
Department of Psychology: Faculty Publications
Computer classifiers have been successful at classifying various tasks using eye movement statistics. However, the question of human classification of task from eye movements has rarely been studied. Across two experiments, we examined whether humans could classify task based solely on the eye movements of other individuals. In Experiment 1, human classifiers were shown one of three sets of eye movements: Fixations, which were displayed as blue circles, with larger circles meaning longer fixation durations; Scanpaths, which were displayed as yellow arrows; and Videos, in which a neon green dot moved around the screen. There was an additional Scene manipulation …
Prosociality And Risk: How Risky Decision-Making In Young Adults Relates To Altruistic Tendencies, Empathic Concern, And Prosocial Peer Affiliation, 2017 University of North Florida
Prosociality And Risk: How Risky Decision-Making In Young Adults Relates To Altruistic Tendencies, Empathic Concern, And Prosocial Peer Affiliation, Sarah J. Beard
UNF Graduate Theses and Dissertations
Adolescence involves an increase in risky decisions, such as reckless driving and illicit substance use, but prosocial characteristics and peer affiliation have yet to be investigated as protective factors. The present study assessed altruistic tendencies, prosocial peer affiliation (PPA), and empathic concern as predictors and moderators of risk-taking, including both self-reported health risks and riskiness in a behavioral task. Young adults from ages 20 to 25 (M = 22.55, SD = 1.38) completed a battery of behavioral tasks (including the Balloon Analogue Risk Task and the Dictator Game) and questionnaires on Amazon MTurk, measuring risk-taking (drunk driving, texting while …
