A Bayesian hierarchical model of lexicographic choice
(University of Missouri--Columbia, 2017)I present a lexicographic, threshold-based model of choice used to evaluate decision makers' preferences among risky alternatives. Using a hierarchical Bayesian frame-work, this model is able to account for observed ... -
Structural-morphometric examination of thalamic nuclei in individuals with Autism spectrum disorders
(University of Missouri--Columbia, 2017)The thalamus has been implicated as a potential source of neural disruption in autism spectrum disorders (ASD). This subcortical nuclear complex is critically involved in sensory processing, an area of deficit in ASD. ... -
Associations between executive functioning, affect-regulation drinking motives and alcohol use and problematic drinking
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Extant literature confirms the direct effects of two key constructs on alcohol use and problematic drinking: (1) motivations to use alcohol to regulate ... -
The effects of tetrahydrobiopterin (BH4) treatement on nonverbal working memory-related brain activations and connectivity in individuals with phenylketonuria
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Previous research suggests that phenylketonuria (PKU) is associated with disruptions in structural and functional connectivity that may contribute to ... -
Model-based recursive partitioning of structural equation models
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The goal of this dissertation is to describe the algorithmic method of model-based recursive partitioning, and to compare different estimation techniques ... -
The Cognitive Reflection Test: a measure of intuition/reflection, numeracy, and insight problem solving, and the implications for understanding real-world judgments and beliefs
(University of Missouri--Columbia, 2017)The Cognitive Reflection Test (CRT) has quickly become a popular measure of individual differences in propensity to reflect versus rely on intuition (Frederick, 2005). The test consists of three questions, and it has been ... -
Stability of risk attitude across choice contexts and frames
(University of Missouri--Columbia, 2017)We report the results of the large-scale study of risk attitude demonstrating substantial heterogeneity both between and within decision makers across three risky choice contexts: financial, mortality and climate change. ... -
Age at first use and later substance involvement: characterizing genetic and environmental pathways for tobacco, alcohol, and cannabis
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Behavioral genetic studies have provided insights into why early substance use initiation is associated with increased risk for disorder. Few ... -
The nonsymbolic quantitative rudiments of mathematics proficiency in early childhood
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A broad synthesis of comparative and developmental research on numerical cognition suggests that humans share with nonhuman animals, an evolutionarily ... -
Striatal functional activation and psychosis risk
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The striatum is involved in learning from feedback. Psychosis is strongly related to increased striatal dopamine. The goal of the current research is ... -
Examination of choice preference structures in a sexual risk paradigm
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Sexually transmitted infections (STIs) are a serious public health concern worldwide. In the United States, young adults are at particularly high risk ... -
Can mindfulness meditation reduce the tendency to justify the status quo?
(University of Missouri--Columbia, 2017)System justification theory suggests that advantaged groups in society frequently express ingroup favoritism and outgroup bias, whereas disadvantaged groups express outgroup favoritism. These tendencies are likely to occur ... -
Serotonin transporter polymorphism and stress effects on gut microbiota at various time points in pregnancy
(University of Missouri--Columbia, 2017)Prenatal stress (stress experienced by the mother while pregnant) has been shown to greatly affect the health of a child. Still, not all offspring who experience prenatal stress will suffer poor outcomes. Maternal genetics ... -
Evidence-based treatment strategies in youth mental health treatment as usual: results from a national survey
(University of Missouri--Columbia, 2017)Despite widespread calls for the integration of evidence-based treatments (EBTs) into treatment as usual (TAU) for youth mental health problems, the success of such efforts is unclear. Existing survey research suggests ... -
Electrophysiological correlates of orienting retrieval to remote and recent memories: effects of an episodic specificity induction
(University of Missouri--Columbia, 2017)The present set of experiments employed event-related brain potentials (ERPs) to investigate differences in how individuals orient retrieval to memories from different times. Experiment 1 investigated whether ERP effects ... -
Reasoning and memory: multiple simple response strategies are used in visual working memory for color-orientation binding
(University of Missouri--Columbia, 2017)Recent research has examined the how effectively people use the information in working memory (WM) when reasoning about that information is required in a recognition memory task (Chen and Cowan, 2013; Hardman and Cowan, ... -
Testing for incidental reactivation of episodic information during memory retrieval : an electrophysiological study
(University of Missouri--Columbia, 2016)Neuro-computational models of memory posit that successful episodic retrieval is accompanied by reactivation of the cortical representations that were active during encoding. Several fMRI and EEG studies have shown that ... -
