A multi-method analysis of the acquired preparedness model of risk for alcohol problems
(University of Missouri--Columbia, 2016)
The acquired preparedness model (APM) integrates both general risk factors and alcohol-related cognitive factors to understand the development of alcohol use and its associated problems. The present project utilized an ...
The social ecology of aggression in youths with autism spectrum disorder
(University of Missouri--Columbia, 2016)
More than half of youths with autism spectrum disorder (ASD) behave aggressively toward other individuals. Although a wide range of individual and social ecological(e.g., family, peer) variables have been linked with ...
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 ...
Prepulse inhibition of the post-auricular reflex
(University of Missouri--Columbia, 2016)
It is well established that a weak lead stimulus will inhibit the startle response to a more intense subsequent stimulus, given an appropriate lead time (i.e. 80-400 ms). This effect is termed prepulse inhibition (PPI), ...
Investigating how bottom-up and top-down systems relate to alcohol use and alcohol use disorder
(University of Missouri--Columbia, 2016)
Throughout the field of psychology, there has been increasing interest in dual-systems models of explaining behavior. Specifically, these models propose that behaviors is due to a bottom-up, emotional system (e.g., reactions ...

Evaluation of risk attitude as a predictor of substance related risk taking
(University of Missouri--Columbia, 2016)
Decision making is a complex process influenced by a number of factors. Mathematical models of risk have been developed to deconstruct the decision making process into the components that are most influential. Risk attitude, ...
Metaphor as a communication strategy for reducing health disparities for Latina women
(University of Missouri--Columbia, 2016)
Racial and ethnic health disparities exist in a multitude of health domains, including higher incidence rates of cancer within minority populations and premature deaths associated with cancer. To address this problem, it ...
Event-related potential correlates of feedback anticipation during motor learning
(University of Missouri--Columbia, 2016)
Stimulus-preceding negativity (SPN), an ERP component that reflects the anticipation of feedback and other motivationally salient stimuli, has been proposed to play an important role in reinforcement learning. However, the ...
An experimental investigation of drunk personality using self and observer reports
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Research has shown that drinkers' “typical drunk personalities” are different from their “typical sober personalities” on each factor of the Five-Factor ...
Investigating the early processes of person construal using ERPs
(University of Missouri--Columbia, 2016)
According to the dynamic interactive theory of person construal (Freeman & Ambady, 2011), upon perception of a person, multiple social categories become simultaneously active and are refined through the integration of ...
Testing the Bayesian brain hypothesis in visual perception
(University of Missouri--Columbia, 2016)
Bayesian ideal observer theory describes perception as an ideal integration of sensory information with prior knowledge to produce optimal responses. Bayesian ideal perception models are popular in sensory domains; however, ...
The effect of mGluR7 antagonist treatment on a dopamine-induced murine model of obsessive-compulsive disorder
(University of Missouri--Columbia, 2016)
Obsessive-compulsive disorder (OCD) is an incapacitating anxiety disorder characterized by unwanted, intrusive thoughts that lead to repetitive, ritualistic behaviors. Current treatments for OCD are only efficacious in a ...
Effects of common and rare GABAergic gene variation on alcohol use and antisocial behavior

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] There is a preponderance of nonhuman animal studies that suggest an evolutionary conserved ability to represent time, number, and rate. Infant cognition ...
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 ...
