A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot
A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot
Graduate Theses, Dissertations, and Problem Reports
Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …

Comparing Measures Of Physical Activity Intensity, Duration, And Frequency Using Receiver Operator Characteristic Curve Analyses, Abigail M. Nehrkorn-Bailey
Graduate Theses, Dissertations, and Problem Reports
The United States Department of Health and Human Services (HHS) recommends adults to engage in weekly moderate- or vigorous-intensity physical activity based on its association with various physical and psychological health benefits (HHS, 2008; Schoenborn, Adams, & Peregoy, 2013). These physical activity recommendations contain important information for three physical activity components: intensity, frequency, and duration. The current physical activity literature contains gaps, with a lack of specificity for which components are being studied. Although some of the literature does describe the physical activity components, there are many discrepancies in the level of agreement across subjective and objective measures, along with …
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports
Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …
