Affective modulation of post-auricular reflexes to serial probes : a test of the nursing hypothesis
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The post-auricular reflex (PAR) is a vestigial microreflex which is thought to be a component of startle. However, unlike prototypical components of ...
Examination of mu-Opioid Receptor Activation in the Nucleus Accumbens on Baseline Diet Preferences in Rats Selectively Bred to Run Long or Short Distances
(University of Missouri--Columbia, 2015)
The obesity epidemic and associated diseases are a direct result of both diet choice and inactivity, as overconsumption of palatable foods and a sedentary lifestyle invariably precede the onset of weight gain. Our laboratory ...
Developing a computer coding scheme for the implicit achievement motive
(University of Missouri--Columbia, 2015)
Implicit motives are measured using a projective assessment, the Picture Story Exercise (PSE), involving labor-intensive coding of participant-generated writing. The present research uses insights from previous attempts ...
The motivational primacy of environmental coherence : self-derogation and the experience of meaning in life
(University of Missouri--Columbia, 2015)
Although the human tendency to make self-serving attributions is well-documented, not all behaviors and cognitions are primarily self-serving. Victims blame themselves for uncontrollable circumstances and individuals ...
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 ...
Game violence, game difficulty, and 2D:4D digit ratio as predictors of aggressive behavior
(University of Missouri--Columbia, 2015)
Previous research efforts have sought to determine whether violent video games cause increases in aggressive behavior. The resulting literature is controversial. Those finding the effect may not have the desired degree of ...
Resource-depletion : outcome of failed energy management or adaptive emotion?
(University of Missouri--Columbia, 2015)
The purpose of this study was to determine whether people have a limited self-control ability. Past research has shown that when people controls themselves they are worse at controlling themselve afterwards. So, for instance, ...
Speech symptoms in Schizophrenia and relationships with working memory, goal maintenance, and processing speed
(University of Missouri--Columbia, 2015)
People with schizophrenia exhibit wide ranging cognitive deficits, including slower processing speed (i.e., speed of executing task components). Speech symptoms, such as disorganized speech and alogia, have been associated ...
Use of score-based tests in IRT Models
(University of Missouri--Columbia, 2015)
Measurement invariance is a fundamental assumption in item response theory models, where the relationship between a latent construct (ability) and observed item responses are of interest. Violation of this assumption would ...
Estimating working memory capacity for lists of nonverbal sounds
(University of Missouri--Columbia, 2011)
Working memory (WM) capacity limit has been extensively studied in the domains of visual and verbal stimuli. The previous studies have suggested a constant WM capacity of typically about 3 or 4 items, based on the number ...
CDPPB reverses an NMDA receptor antagonist-induced deficit in inhibitory avoidance and conditioned taste aversion learning in rats
(University of Missouri--Columbia, 2010)
Rats administered a metabotropic glutamate receptor 5 (mGluR5) positive allosteric modulator (PAM), CDPPB, and/or an NMDA receptor antagonist, MK-801, were given inhibitory avoidance or conditioned taste aversion training. ...
Impaired spatial learning and increased locomotor activity in TgCRND8 mice as a model of Alzheimer's disease
(University of Missouri--Columbia, 2010)
This study provides a behavioral characterization of the TgCRND8 mouse strain, an APP (double-mutant) transgenic model of Alzheimer's disease (AD). While past research focused mainly on 2-5 month-old TgCRND8 mice, this ...
The effects of an mGluR7 agonist, AMN082, on conditioned taste aversion
(University of Missouri--Columbia, 2010)
Metabotropic glutamate receptors impact learning and memory. The current studies examined the effects of AMN082, a recently discovered selective metabotropic glutamate receptor 7 (mGluR7) allosteric agonist, on the acquisition ...
The role of intentions in the pursuit of happiness
(University of Missouri--Columbia, 2010)
Are intentions to become happier through interventions helpful or detrimental to the pursuit of happiness? Although Schooler, Ariely, and Lowenstein (2003) suggest that intentionally pursuing happiness is a self-defeating ...
Associations between maternal awareness and children's fearfulness and anxiety
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Fearful temperament in the toddler years is a well-established precursor to risk for childhood anxiety. Less is known about the mechanisms by which ...
Ecological momentary assessment of affective instability, impulsivity, and alcohol use in borderline personality disorder
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The present study examined the momentary and within-day relationships between mood states, impulsivity, and alcohol use. Participants included 48 ...
Does hangover have an acute impact on future drinking?
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Hangover is a common adverse effect of excessive drinking. According to popular culture, hangover purportedly leads to resolutions to quit drinking ...
The relationship between negative affectivity, affective instability, and interpersonal stressors in borderline personality disorder
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Using ecological momentary assessment, this study found a relationship between daily negative affect, affective instability, and negative interpersonal ...
Multilevel models for intensive longitudinal data with heterogeneous error structure : covariance transformation and variance function models
(University of Missouri--Columbia, 2008)
Recent developments in data collection methods in the behavioral and social sciences, such as Ecological Momentary Assessment (EMA) enables researchers to gather intensive longitudinal data (ILD) and to examine more detailed ...
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 ...
