Peer Conversation About Substance Use, Danielle M. Pillet-Shore

Communication

What happens when a friend starts talking about her own substance use and misuse? This article provides the first investigation of how substance use is spontaneously topicalized in naturally occurring conversation. It presents a detailed analysis of a rare video-recorded interaction showing American English-speaking university students talking about their own substance (mis)use in a residential setting. During this conversation, several substance (mis)use informings are disclosed about one participant, and this study elucidates what occasions each disclosure, and how participants respond to each disclosure. This research shows how participants use casual conversation to offer important substance (mis)use information to their friends …

Examining The Relationship Between Confusion And Learning: A Descriptive Meta-Analysis, Dara L. Mcweeney, Aaron Y. Wong, Caitlin Mills

Honors Theses and Capstones

Previous research into confusion and learning neglects to investigate how this relationship varies when faced with impact factors such as multiple types of affect and learning measurements, learning environment, or grade level. Moreover, past research also reports di-verse effect size values for this relationship, making the correlation ambiguous. As such, the current research seeks to reconcile these nuances between confusion and learning through a meta-analytic approach. In this analysis, it was found that there was no relationship between confusion and learning gains, or in the subgroup analysis of grade level. Since only one impact factor, grade level, was analyzed, it …

Increment And Decrement Effects In Motion Induced Blindness, Sofia C. Lombardo

Honors Theses and Capstones

Motion induced blindness (MIB) refers to the perceptual disappearance of a stationary stimulus in the presence of a motion mask. The current study investigated the degree to which afterimages affect MIB inhibition when measured as a contrast detection threshold in a modified replication of White et al. (2020). Adult participants (N = 3) with normal or corrected-to-normal eyesight completed a series of target detection tasks while viewing a standard MIB stimulus with the motion mask removed that consisted of increment versus decrement inducer and target components. A univariate ANOVA data analysis procedure revealed a significant afterimage effect (Scheffé p < 0.0253) on contrast detection threshold was found for targets presented at an interstimulus interval of 500 ms. This effect was stronger for decrement targets compared to increment targets in the decrement inducer conditions. Based on a comparison with previous research in which the MIB effect was found to endure across interstimulus intervals up to 15500 ms, the current findings indicate that afterimages do not significantly influence contrast detection thresholds for MIB. Further research is necessary for determining the strength and duration of afterimage effects on contrast detection thresholds in MIB that may be caused by interaction with the motion mask.

Corticostriatal Pathway Inactivation And Connections To Associative Learning With Nicotine Stimulus In Rats, Anna Kalinowski

Honors Theses and Capstones

The main concern of this study is looking into the neural mechanisms of associative learning with a nicotine stimulus. The goal of this study was to find out if inactivating the corticostriatal pathway through DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) inhibited goal-tracking behavior in rats. In this experiment, rats underwent two surgeries. One was to inject DREADDs into the infralimbic cortex and the other in the dorsomedial caudate-putamen (dmCPu). Rats were initially trained on levers through water deprivation. Once they reached the criterion, they moved on to the self-administration phase. After the rats were trained in self-administration sessions …
