Controlling The Narrative: The Effects Of Media Coverage On Fear Of Crime And Socio-Political Ideology, Andrew Koppelman Apr 2024

Controlling The Narrative: The Effects Of Media Coverage On Fear Of Crime And Socio-Political Ideology, Andrew Koppelman

Theses

Several decades of study have established an understanding that media have a unique power to influence the perspectives and worldviews of audiences. This phenomenon has been explored through the lenses of Social Learning and Cultivation theory, wherein media appeal to base human tendencies of self-preservation and teaches audiences how to maximize rewards for their actions by acting as a sort of instructor or friendly warning from members of the community. While prior studies have suggested the presence of this effect, little research has been devoted to understanding the ways that this may influence behaviors in viewers. My research seeks to …


A Comparison Of The Relative Magnitude Of Combinations Of Relapse Types In Rats, Mary Bridges Apr 2024

A Comparison Of The Relative Magnitude Of Combinations Of Relapse Types In Rats, Mary Bridges

Theses

Applied behavior analysis uses scientifically derived methods to create treatments for socially significant behaviors. A threat to these successful treatments is the recurrence of previously reduced behavior (i.e., relapse). Relapse can be categorized into several types depending on the variables that induce relapse. Three types prevalent in clinical settings are reinstatement (i.e., induced by re-exposure to reinforcers or stimuli paired with the target behavior), renewal (i.e., induced by changes in context), and resurgence (i.e., induced by worsening of alternative reinforcement). Because relapse is harmful to long-term treatment maintenance, prior research has developed and tested mitigation strategies for these relapse types, …


Selfies And The Self: The Influence Of Instagram Posting On Self And Cognition, Giovanni Castillo Jul 2022

Selfies And The Self: The Influence Of Instagram Posting On Self And Cognition, Giovanni Castillo

Theses

Research on Social Networking Sites (SNS) has shown a variety of both beneficial and detrimental psychological and cognitive outcomes associated with high frequency usage. We conducted an online study consisting of a series of questionnaires and a working memory task to explore the relationship between Instagram use intensity and cognition. The present study first investigated the relationship between Instagram (IG) use intensity, rumination, and cognitive failures. We randomly assigned participants into a selfie-posting, selfie-sending, or likes/comments reporting condition to determine whether selfie-posting behavior affects working memory performance. While we did not find significant associations between IG use intensity, rumination, and …


The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee Jul 2022

The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee

Theses

As seen in decades of psychology research, preferences play a major role in driving the decision-making process in both humans and animals. Researchers have advocated for using the technique of experimental evolution as a way to address some of the foundational questions on preferences. These preferences can also affect what is later learned and how well new experiences are learned. Salience is usually mentioned as an important component of what could influence preferences. Animals such as Drosophila melanogaster, that lay eggs without any additional maternal or paternal care, it is important to be selective when deciding where to lay …


Examining Own-Race Bias: A Cooperation And Memory Study Using Diverse Emojis, Jillian Franks Aug 2021

Examining Own-Race Bias: A Cooperation And Memory Study Using Diverse Emojis, Jillian Franks

Theses

Other-race-effect or own-race bias is a well-documented phenomenon in memory. Findings suggest that humans are better at recognizing and remembering faces of their own race than other races. Previous research suggests that these results are due to a lack of interracial contact or exposure to other racial groups. Evidence from previous studies has demonstrated that individuals process own-race faces differently than other-race faces, paying more attention to more salient features that become better encoded. While there is empirical support for both hypotheses, it has yet to be studied if the other-race effect for memory extends to representational human faces, for …


Different Exercise Tendencies Modulate Behavioral And Molecular Changes To Opioid Or Exercise-Induced Reward, Amanda Titus Apr 2020

Different Exercise Tendencies Modulate Behavioral And Molecular Changes To Opioid Or Exercise-Induced Reward, Amanda Titus

Theses

Reward changes were observed in rodents with different exercise tendencies by utilizing the conditioned place preference paradigm. Adult male Wistar rats with distinct phenotypes (low volume runners, high volume runners, and wild-type) were given access to a running wheel or an injection of morphine as a rewarding stimulus. There was no difference observed in the strength of conditioned place preference between the rewarding stimuli. Extinction was significantly more effective in low volume runners than high volume runners and wild-type animals, as was observed in the lower percentage of time spent in their assigned conditioning chamber. These findings suggest that low …


Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack Aug 2018

Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack

Theses

Bubble stream production in belugas has been poorly characterized and its function is not well understood. I examined behavioral states when producing bubble streams (“bubbling”), and when bubbling calls, to determine whether bubbling was significantly associated with a particular call category or behavioral state. Using 19 hours of video and audio recordings collected over a two-day period, I quantified bubble streams of a 4-month old calf and an unrelated adult female housed together. Based on the overall activity budgets and pool of vocalizations for both animals, I calculated the expected counts of bubble streams with and without vocalizations, assuming that …
