Methamphetamine-induced hyperactivity and reinforcement learning in rats selectively bred for high and low voluntary running
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The goal of the present research was to assess two lines of Wistar rats selectively bred for high (HVR) and low (LVR) voluntary wheel running, in comparison to a line of control...
Event-related potential correlates of feedback anticipation during motor learning
(University of Missouri--Columbia, 2016)
study, 60 young adult subjects were required to make four precisely timed key-press responses with a designated hand. Instructions for this timing were indicated by a pattern composed of four dots and line segments shown on the computer screen. After a...
Do infants selectively imitate a transitive and an intransitive agent?
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Previous research showed that in imitative learning, infants seemed to care about the reliability of the model marked by group membership or conventionality of behaviors. Current...
The effects of approach-avoidance behaviors on goal appraisals
(University of Missouri--Columbia, 2009)
Previous research has demonstrated that behaviors associated with approach and avoidance motivation can influence cognitions in line with the particular motivational state (e.g., Friedman & F̈örster, 2008). The present ...
A bayesian investigation into inhibition mechanisms of contrast and assimilation
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The ability to inhibit distractors within an environment while focusing on specific information is crucial to proper functioning. In most inhibition tasks, such as Stroop, the to...
An evolutionary perspective of the effects of emotion on the post-auricular reflex
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The post-auricular reflex (PAR), contrary to other components of the startle reflex, is potentiated by positive emotions and inhibited by negative emotions. We investigated...
To discover or to create : metaphors and the true self
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Two studies were conducted to examine how the metaphors of discovery and creation influence the perceived validity of the true self. It was hypothesized that the metaphor...
Paying attention to binding: is the associative deficit of older adults mediated by reduced attentional resources?
(University of Missouri--Columbia, 2005)
One notion put forth to explain age-related, episodic memory problems is the associative-deficit hypothesis, stating that they are due to older adults' decreased binding ability (i.e., their ability to encode separate ...
Cost-benefit analysis of multisystemic therapy with serious and violent juvenile offenders
(University of Missouri--Columbia, 2007)
This study investigated the economics of multisystemic therapy (MST) vs. individual therapy (IT) using longitudinal rearrest data from a 13.7-year follow-up (Schaeffer & Borduin, 2005) of a randomized clinical trial with ...
Cognitive load and time based forgetting
(University of Missouri--Columbia, 2009)
Recently, various researchers have claimed that time does not play a direct role in shortterm forgetting. Instead, they claim that time is only related to forgetting because it is correlated with other factors that cause ...
Forgetting in short term memory : the effect of time
(University of Missouri--Columbia, 2008)
Forgetting in short-term memory has been studied extensively and yet no consensus has emerged to explain its cause. Two theories continue to provide competing explanations of forgetting in short-term memory: decay and ...
Who did what?: age-related differences in memory for people and their actions
(University of Missouri--Columbia, 2006)
The associative-deficit hypothesis (ADH), proposed by Naveh-Benjamin (2000), holds that the decline in episodic memory that accompanies aging is at least partially due to an inability to bind single units of information ...
How sweet it is to be loved by you : toward an understanding of why close relationships buffer existential fear
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Theory and research suggest that close relationships help to buffer against existential fears associated with the awareness of death (Mikulincer Florian, & Hirschberger, 2003...
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 explicitly testing a...
Examining perceptual load capacity in Autism Spectrum Disorders and trait anxiety
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Perceptual load theory posits that there is a limited amount of information a person can perceive at any given time and information is processed automatically until reaching...
Multisystemic therapy across the lifespan : a 21.9-year follow-up to a randomized clinical trial with serious and violent juvenile offenders
(University of Missouri--Columbia, 2008)
In this study, we examined the long-term criminal and civil court outcomes of 176 serious and violent juvenile offenders who had participated in either multisystemic therapy (MST) or individual therapy (IT) in a randomized ...
Exploring personality factors associated with treatment-seeking behavior among individuals with bulimia nervosa
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There are numerous treatments that have been developed for bulimia nervosa (BN), but few individuals with BN seek treatment. It is important to understand factors associated...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The current studies looked to expand upon the wealth of knowledge in the social and behavioral sciences that link scarcity and value. Utilizing exemplar-cue theory...
Effects of musical collaboration on intergroup attitudes
(University of Missouri--Columbia, 2020)
Music is an important presence in our world, thought to be universal in human societies. The ubiquity of music has led some to postulate that it might have an important evolutionary purpose. One theory about the purpose of music is that it helps...
