Using Undergraduate Learning Assistants To Aid In Course Redesign, Jeffrey Pavlacic, Megan Culp, Summer Harvey, Christie Cathey, Erin Buchanan
Modern Psychological Studies
Research has identified potential difficulties for students enrolled in large classes. Large classes reduce opportunities for faculty-student interaction, which may predict decreased learning, retention rates, and student performance. It is therefore important to increase opportunities for faculty-student interaction. One successful tactic for increasing this interaction in large classes involves the utilization of undergraduate peers as class assistants. This manuscript describes the implementation of Undergraduate Learning Assistants (ULAs) in large sections of Introductory Psychology at Missouri State University, utilizing data collected prior to this manuscript. Further, this manuscript is a review of the implementation of ULAs at Missouri State submitted by …
Will D-Amphetamine’S Effect On Impulsive Choice Be Consistent When The Environmental Context Changes By Using Decreasing Delays To Reinforcement?, Elizabeth M. Janeiro, Jenny E. Ozga, Karen G. Anderson
Will D-Amphetamine’S Effect On Impulsive Choice Be Consistent When The Environmental Context Changes By Using Decreasing Delays To Reinforcement?, Elizabeth M. Janeiro, Jenny E. Ozga, Karen G. Anderson
Modern Psychological Studies
Impulsivity (choosing a smaller, more immediate reward over a larger, more delayed reward) and substance abuse are positively correlated. It is important to understand how factors like delay to reward and drug effects determine impulsive choice, which can be studied using animal models. This study evaluated impulsive choice in rats, where delays to the larger reward (three food pellets) were presented in decreasing order versus one food pellet delivered immediately. Then, effects of d-amphetamine were assessed. It was found that in three of four rats, d-amphetamine increased impulsive choice when the larger option was presented with decreasing delays. This effect …
An Investigation Of Creativity's Perceived Impact On Psychological Well-Being, Diana-Gabriela Boicu
An Investigation Of Creativity's Perceived Impact On Psychological Well-Being, Diana-Gabriela Boicu
Modern Psychological Studies
This study aimed to investigate creativity’s influence on psychological well-being, due to identified contradictions in predominantly quantitative previous research. For a greater understanding, a phenomenological qualitative design has been used. Reflecting Ryff’s (1989) Scale of Psychological Well-being within semi-structured interviews, data was collected from 11 art students from the University of Bedfordshire. Inductive thematic analysis revealed the following themes: Creative compass, Social Interactions, Volition, Perceived achievements and self-attitude, Self-efficacy and lifestyle. Positive implications have been found on all dimensions of psychological well-being, apart from autonomy. The qualitative method of enquiry has allowed for an exploration of this effect and of …

In the literature, there have been many studies measuring homophobic attitudes of heterosexual people. However, there is limited research on behavioral aspects of homophobia. We attempted to develop a new scale measuring homophobic behaviors of heterosexual students toward gay and lesbian individuals on campus life. We developed BGLC (Behaviors toward Gays and Lesbians on Campus) Scale and validated the scale by comparing it with Age Universal I-E Scale, Homophobic Behaviors of Students Scale (HBSS) and Future Engagement in Activities Concerning Homosexual People (FEACHP) in order to study discriminant, convergent and criterion validity, respectively.

Modern Psychological Studies
It is infrequently recognized that healthy individuals occasionally obtain impaired scores on neuropsychological measures. This research was conducted to determine how often healthy undergraduate research participants obtain impaired scores on popular measures of executive functioning. Specifically, performance on the Delis-Kaplan Executive Function System (D-KEFS) Trail Making and Color-Word Interference subtests was investigated in a sample of 335 undergraduate research participants. Rates of impaired performance varied across subtests and ranged from 11% (Color-Word Interference Word Reading) to 3% (Trail Making Test Motor Speed). In general, individuals with greater intellectual functioning had higher scores and fewer impaired scores. Findings are consistent with …
Measurement Of The Propensity To Trust Automation, Sarah Ann Jessup
Measurement Of The Propensity To Trust Automation, Sarah Ann Jessup
Browse all Theses and Dissertations
Few studies have examined how propensity to trust in automation influences trust behaviors, those which indicate users are relying on automation. Of the published studies, there are inconsistencies in how propensity to trust automation is conceptualized and thus measured. Research on attitudes and intentions has discerned that reliability and validity of measures can be increased by using more direct and specific language, which reduces ambiguity and increases the ability to predict behavior. This study examined how traditional measures of propensity to trust automation could be adapted to predict whether automation is deemed as trustworthy (perceived trustworthiness) and whether people behave …
Self-Efficacy - Performance Discrepancies: Examining How Over- And Underestimations Of Ability Progress Over Time, Kent Cooper Etherton
Self-Efficacy - Performance Discrepancies: Examining How Over- And Underestimations Of Ability Progress Over Time, Kent Cooper Etherton
Browse all Theses and Dissertations
The current study examined how over- and underestimations of ability progress with increasing experience completing a task. Prior research has demonstrated inconsistent effects when investigating the relationship between self-efficacy and performance at the within-person level of analysis, often theorizing distinct effects of over- versus underestimating one's ability level. Thus, the current study investigated the discrepancy between self-efficacy, one's belief in their capability to accomplish some task, and actual performance levels. The current study replicated findings that self-efficacy converges on performance over time and extended prior research by demonstrating the rate of convergence might be affected by the size of initial …

Moral injury (MI) results from perpetration of or exposure to distressing events, known as morally injurious events (MIEs), that challenge moral beliefs and values. Due to the type of involvement in recent military conflicts, many veterans report MIEs that may cause dissonance and, in turn, MI. Although 2 existing measures assess MIEs, neither currently assesses the defining characteristics of MI (i.e., guilt, shame, difficulty forgiving self and others, and withdrawal). The present study reports the initial psychometric test of a modified version (Robbins, Kelley, Hamrick, Bravo, & White, 2017) of the Moral Injury Questionnaire—Military version (MIQ-M; Currier, Holland, Drescher, & …

Background: The prevalence of maternal perinatal obesity is rising, and in turn, increases health risks and morbidity for both mother and child. Past evidence suggests the preconceptional Strong Healthy Women (SHW) intervention can reduce multiple biobehavioral risk factors for adverse perinatal health. The SHW intervention, however, was time- and resource-intensive to deliver. Mobile health (mHealth) technologies provide an opportunity to expand intervention reach while reducing implementation cost and burden. Previous research suggests that preconceptional women are broadly supportive of using smartphones for behavior change, yet few studies have elicited their specific preferences for a targeted mHealth intervention. The objective of …
Heritable Variation In Reward Sensitivity And Impulsive Cction And Choice In A Genetically Diverse Inbred Mouse Panel, Lauren S. Bailey
Heritable Variation In Reward Sensitivity And Impulsive Cction And Choice In A Genetically Diverse Inbred Mouse Panel, Lauren S. Bailey
Graduate Dissertations and Theses
Research in animal models and human subjects points towards reward sensitivity and impulsivity as being characteristics that predict greater positive subjective responses to stimulant drugs. The Collaborative Cross (CC) recombinant inbred mouse strains and their inbred founders are a powerful genetic reference panel that has potential as a tool for revealing genetic correlations. The CC/DO founder strains were used to examine the heritability of reward sensitivity and impulsivity traits. Founder strains were tested for activity in an open field, reward sensitivity, and reversal learning (impulsive action) or delay discounting (impulsive choice). Significant heritability for anticipatory responding within the reversal task, …
The Influence Of Television Pacing On Attention And Executive Functioning, Timothy Lavigne
The Influence Of Television Pacing On Attention And Executive Functioning, Timothy Lavigne
Graduate College Dissertations and Theses
Television shows, especially cartoons, are one of the most common types of media in children’s lives. Although there is a well-established connection between television exposure and difficulties with attention, it is unclear if all types of television are equally impactful. Given the amount of time children are exposed to television, there is a need to better understand which components of shows may or may not impact one’s attentional and executive functioning abilities. One such factor is the pace of the content. The current study expands on this limited area of the literature by utilizing a 9-minute 30-second long cartoon video, …
Effects Of Chemogenetic Inhibition Of Dopamine Transporter- Or A2a-Expressing Neurons On Spontaneous Activity And Motivation To Consume A Palatable Food Reward, James D. Wherry
Graduate Dissertations and Theses
Dopamine (DA) transmission in the striatum influences the motivated pursuit of rewarding stimuli. Pharmacological and opto- and chemo-genetic studies have suggested that the release of DA onto D2+/A2A+-expressing striatopallidal neurons, plays a role in this process. To determine the potentially dissociable roles of DA-releasing ventral midbrain and striatopallidal neurons on motivational processes, we employed double transgenic mice that expressed inhibitory DREADDs—designer receptors that are activated only by otherwise inert ligands—only in dopamine transporter (DAT) or A2A adenosine receptor (A2A) expressing neurons, allowing us to transiently inhibit either DA-releasing neurons (DATcre/DREADD) or striatopallidal neurons (A2Acre/DREADD) during various tests. In the first …

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of …

Lesbian women face unique sexual minority stressors (SMS) because of their stigmatized and marginalized status in society. Existing studies of SMS are primarily cross-sectional and use global measures of SMS. The goal of the present study was to develop a brief daily measure of SMS for use in daily diary or ecological momentary assessment studies. Existing retrospective measures of SMS were reviewed, resulting in an initial pool of 29 items. Thirty-eight lesbian women (Mage = 24.3 years, range: 19–30 years) completed a daily web-based survey including the SMS items for 12 days. Two response scales were tested; participants were randomized …
