The effect of emotional facial expressions on item and associative memory in younger and older adults
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Research suggests that emotional stimuli can modulate item and associative memory performance. While enhancing the memory for individual item components, ...
Classification problems in growth mixture modeling
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Growth mixture modeling can be used for two purposes: 1) to identify mixtures of normal sub-groups, and 2) to approximate oddly shaped distributions ...
Effects of a metabotropic glutamate receptor 5 positive allosteric modulator, CDPPB, on spatial learning in rodents
(University of Missouri--Columbia, 2012)
Metabotropic glutamate receptor 5 (mGlu5) has been implicated in a variety of learning processes and is important for aversive learning tasks. The present studies used an mGlu5 receptor positive allosteric modulator, ...
Genetic and environmental influences on impulsivity and coping motives for alcohol across emerging and young adulthood
(University of Missouri--Columbia, 2013)
Variation in the gene encoding the dopamine D4 receptor (DRD4) may moderate the influence of environments (i.e., a gene-environment interaction, GXE) on personality traits and motives associated with alcohol use disorders. ...
The effect of mGluR2 3 agonist, LY379268, and a mGluR4 positive allosteric modulator, VU0155041, on conditioned taste aversion
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Metabotropic glutamate (mGlu) receptors are known to mediate learning and memory. Although evidence indicates a role for mGlu receptors (e.g., mGlu5) ...
Positive affect, intuitive processing, and visual encoding
(University of Missouri--Columbia, 2012)
The effects of positive affect (PA) on cognitive outcomes have been studied extensively. These effects map on squarely to a Cognitive-Experiential Self Theory (CEST) framework (Epstein, 1991; 1994). One component of CEST ...
EGCG and voluntary exercise : an examination of treatment effects using the TgCRND8 mouse model of Alzheimer's disease
(University of Missouri--Columbia, 2013)
Previous work with the TgCRND8 mouse model of Alzheimer's disease has shown that voluntary exercise implemented for long time periods (5-months) and starting at very young ages (1-month), prior to the development of disease ...
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 ...
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 ...
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 ...
Genetic influences on non-suicidal self-injury and suicidal thoughts and behaviors
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Though non-suicidal self-injury (NSSI) and suicidal thoughts and behaviors (STBs) often co-occur, very little is known about the shared and unique ...
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 ...
