Alcohol consumption, executive function and risky decision making
(University of Missouri--Columbia, 2009)
Previous research has shown that alcohol intoxication can adversely affect behavior by impairing higher cognitive function (e.g., Giancola, 2000) and can lead to increased risk-taking (Leigh, 1999) via impaired executive ...
Broadening the perspective on employee absenteeism : the effects of work group and nonwork factors
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The present study examined employee absenteeism in relation to variables new to absenteeism literature while addressing several methodological issues highlighted...
An assessment of inhibition in the Simon task
(University of Missouri--Columbia, 2009)
Different from some other context tasks, the Simon task is featured with a congruency effect decreasing with increasing RT. Ridderinkhof proposed a two route model to account for the negative slope of this congruency effect ...
Assessing single- and dual-process accounts of recognition memory using hierarchical Bayesian models
(University of Missouri--Columbia, 2010)
to assess the veracity of previous claims. The results of this hierarchical modeling suggest that 1) ROC asymmetry, which has served as strong evidence for particular one and two-process model, is not an artifact of averaging, 2) The Yonelinas two...
The precision of retrieving temporal information : behavioral and electrophysiological studies
(University of Missouri--Columbia, 2020)
The knowledge of when an event took place provides benefits to episodic memory, such as distinguishing among multiple traces and learning event sequences. As a tool for understanding memory, time is appealing given its ...
Electrophysiological studies of identifying and modulating the preparatory strategic processes involved in episodic memory retrieval
(University of Missouri--Columbia, 2018)
experiments that addressed this issue by employing an analysis approach focusing on the pre-stimulus period of retrieval test trials and capitalizing on the increased sensitivity of multivariate pattern analysis (MVPA) of oscillatory activity. Experiment 1...
The effect of Parkinson's disease on learning-related slow potentials and emotion
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The dopaminergic reward system is the focus of intensive research because of its relevance to disorders such as addiction, obesity, Parkinson's disease ...
Effects of deep brain stimulation on implicit learning in patients with Parkinson's disease
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis extends previous work examining the effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) on cognitive functioning by ...
Racial discrimination and mental health : temporal dynamics and neurocognitive moderators
(University of Missouri--Columbia, 2020)
Experiencing racial discrimination is related to both mental and physical health (Mays et al., 2007; Pascoe and Richman, 2009; Schmitt et al., 2014). However, much of this research focuses on population-level relationships using cross...
Evaluation of vmpfc-amygdala resting state functional connectivity as a transdiagnostic moderator of momentary sadness and rumination
(University of Missouri--Columbia, 2020)
Rumination has been identified as a transdiagnostic feature of emotional distress disorders that exacerbates symptoms of anxiety and depression. It is thought that rumination may be due in part to heightened resting state ...
Resolving the conflict between the discrete-slots and distributed-resources models of working-memory capacity
(University of Missouri--Columbia, 2011)
It is generally accepted that Working Memory is limited in capacity. However, there has been substantial debate over whether this limit in capacity is best described as a finite limit on the number of items that can be ...
Structural-morphometric examination of thalamic nuclei in individuals with autism spectrum disorders
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The thalamus has been implicated as a potential source of neural disruption in autism spectrum disorders (ASD). This subcortical nuclear complex is ...
The effect of Parkinson's disease on learning-related slow potentials and emotion
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The dopaminergic reward system is the focus of intensive research because of its relevance to disorders such as addiction, obesity, Parkinson's disease ...
Association between positive emotion regulation strategies and the reward positivity
(University of Missouri--Columbia, 2018)
Emotion regulation dysfunction is a core feature of Major Depressive Disorder (MDD). Recently, research has begun to focus on positive emotion regulation strategies such as dampening and savoring of positive emotion. ...
Associations between cumulative genetic influence for risk-taking and hazardous alcohol use in two independent samples
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A propensity for risk-taking may be associated with hazardous alcohol-related behaviors especially in men. Prior research indicating substantial ...
Unconscious information progressing in working memory
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Conventionally, the contents of working memory (WM) have been viewed as tightly coupled with conscious awareness. However, recent experimental findings ...
Item response models for the measurement of thresholds
(University of Missouri--Columbia, 2008)
At least since Fechner (1860) described examples of human sensory thresholds, the concept of a threshold has been foundational in psychology. Thresholds exist when a sensation can be so weak that it does not lead to ...
The influence of race on behavior and the neural correlates of expectancy during an economic decision game
(University of Missouri--Columbia, 2018)
I investigated how another person's race influences resource sharing during a social economic decision-making game that depends on trustworthiness. Seventy-eight university students played a behavioral economics Trust Game ...
Observed positive and negative behaviors in children: relation to anxiety and depression symptoms
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Anxiety and depression are difficult to differentiate, especially in children. Research has demonstrated that children's self-reported positive and ...
Short and long-term effects of birth weight and neonatal medical complications on children's emotional and behavioral outcomes
(University of Missouri--Columbia, 2008)
Research consistently indicates that children born low birth weight are at increased risk for poor adjustment outcomes throughout development. Despite a relatively large literature, the mechanisms accounting for the ...
