Increasing Caregiver Reliability on Anecdotal Assessments

Description: Functional analyses are the gold standard of confirming maintaining variables of problem behavior. Despite widespread support, many clinical settings instead use anecdotal assessments. These have been shown to have poor reliability when used by non-experts but can be useful for confirming maintaining variables of problem behavior when agreement has reached a certain level. We used behavior skills training to teach new staff member pairs behavior function to increase their reliability on these a… more

Memories of Troy in Middle English Verse: A Study of "Sir Gawain and the Green Knight," "Troilus and Criseyde," and the "Troy Book"

Description: This thesis explores the influence of the legend of Troy on Sir Gawain and the Green Knight, Chaucer's Troilus and Criseyde, and Lydgate's Troy Book. This study seeks to understand why medieval English Christians held the pagan myth of Troy in such high regard beyond the common postcolonial critique of Trojan ancestry as a justification for political power. I begin by demonstrating how Vergil's Aeneid presents a new heroic ideal much closer to Christian virtue than Homeric values, Aeneas submit… more

Protective Factors for Eating, Shape, and Weight Concerns across Diverse Gender Identities

Description: We ran three MANOVAs in a sample of 422 young adults to examine differences in eating, shape, and weight concerns (i.e., ESW concerns) between gender diverse individuals, ciswomen, and cismen. Additionally, we examined the effects of self-esteem and sense of belonging on ESW concerns. We also tested for interaction (moderation) effects between gender and self-esteem and gender and sense of belonging. Findings indicated that gender diverse individuals experience ESW concerns at a significantly h… more

Using GIFs and Matrix Training to Teach Noun-Verb Tacts to Children with Autism

Description: Verbal behavior is a critical repertoire for children with autism spectrum disorder to acquire. Tacts—verbal behavior evoked by nonverbal stimuli—are important for communicating about the world around oneself. Noun-verb tacts are part of a robust tact repertoire and may be addressed during applied behavior analytic intervention. When acquiring noun-verb tacts, it is important that the speaker learn to respond to many variations of stimuli like novel combinations of learned nouns and verbs, whic… more

Can In-vivo Self-Monitoring Improve Discrete Trial Instruction Implementation?

Description: Beneficial consumer outcomes are most likely when behavior-analytic interventions are implemented with high procedural fidelity (i.e., degree to which the procedure is implemented as intended). Video self-monitoring, which involves teaching staff members to monitor their own procedural fidelity when watching recordings of themselves, can be used to improve and maintain high procedural fidelity, but video self-monitoring requires additional staff time and resources. In-vivo self-monitoring, whic… more

Devotio Moderna and Erasmus: Transforming Piety

Description: The relationship between Erasmus of Rotterdam and the religious movement called the Devotio Moderna, especially the latter's relevance to Erasmian piety, has been a somewhat contentious historiographical issue. This thesis examines that relationship, and asserts that the Devotio Moderna was a crucial formative aspect of Erasmus' religiosity. However, its relevance ought not be overstated, due to the humanist's significant developments away from his spiritual forerunners.

A Different Kind of Political Party: The Relationship between Tabletop Role Playing Games and Political Efficacy

Description: Tabletop role-playing games (TRPGs) present a unique opportunity to study political behavior. In educational settings, role-playing games (RPGs) of all kinds have proven to be valuable educational tools, and even when played for fun, participating in role playing games has been shown to increase one's level of confidence. Knowing this, I designed an experiment to attempt to increase internal political efficacy through the use of a politically-themed TRPG. I took inspiration from the original TR… more
