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