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 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 ...
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 selection in mixture modeling
(University of Missouri--Columbia, 2016)
In the psychological sciences, mixture modeling (also referred to as latent class or latent profile analysis) is very commonly used to find sub-populations within a sample. However, the process by which researchers select ...
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 ...
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, ...
Rate learing in infancy
(University of Missouri--Columbia, 2016)
[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 ...
Effects of common and rare GABAergic gene variation on alcohol use and antisocial behavior
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Epidemiological estimates suggest that nearly half of individuals diagnosed with AUD will also be diagnosed with another mental health disorder, with ...
Lay theories and the correction of mood influences on judgments
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] When people believe their judgments are being unduly influenced by an emotion, how do they attempt to mitigate the influence? This study examined ...
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 ...
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 ...
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 ...
Family-based treatments for serious juvenile offenders : a multilevel meta-analysis
(University of Missouri--Columbia, 2016)
Violent criminal acts and other serious crimes committed by youths result in considerable emotional, physical, and economic effects on these youths, their families, crime victims, and the larger community. Researchers have ...
Cognitive processes contributing to visual working memory performance in individuals with autism spectrum disorder /
(University of Missouri--Columbia, 2016)
Previous investigations of working memory performance in individuals with Autism Spectrum Disorder (ASD) have yielded mixed findings (e.g., Kenworthy, Yerys, Anthony, and Wallace, 2008; Geurts, de Vris, and van den Bergh, ...
