Cocaine-Induced Reinstatement Of A Conditioned Place Preference In Developing Rats: Involvement Of The D2 Receptor, Kimberly A. Badanich, Cheryl L. Kirstein

Psychology Faculty Publications

Reinstatement of conditioned place preferences have been used to investigate physiological mechanisms mediating drug-seeking behavior in adolescent and adult rodents; however, it is still unclear how psychostimulant exposure during adolescence affects neuron communication and whether these changes would elicit enhanced drug-seeking behavior later in adulthood. The present study determined whether the effects of intra-ventral tegmental area (VTA) or intra-nucleus accumbens septi (NAcc) dopamine (DA) D2 receptor antagonist infusions would block (or potentiate) cocaine-induced reinstatement of conditioned place preferences. Adolescent rats (postnatal day (PND 28–39)) were trained to express a cocaine place preference. The involvement of D2 receptors on cocaine-induced reinstatement …

Fmri Reveals The Neural Correlates Of Real And Pantomimed Tool Use In Humans, Joseph Umberto Paciocco

Electronic Thesis and Dissertation Repository

Although functional magnetic resonance imaging (fMRI) can be used to study the neural mechanisms underlying greatly expanded cognitive functions in humans like tool use, surprisingly little fMRI research has been done on actual tool use. In fact, due to technical constraints, most fMRI studies have used pantomimed actions as a proxy for real use. However, human neuropsychology patients who are impaired at pantomiming often improve when handling a tool suggesting potential neural differences. We used fMRI to record brain activation while 13 right-handed participants performed one of two tasks, real or pantomime tool use with one of two tools, a …

Navigating The Diverse Dimensions Of Stereotypes, With Domain Specific Deficits: Processes Of Trait Judgments About Individuals With Disabilities, Christina G. Boardman

Scripps Senior Theses

Stereotype groups are interrelated. For example, in Australia, New Zealand, and the United States, racial minorities are referred to special education at a much higher rate than are majority racial groups (Tse, Lloyd, Petchkovsky, and Manaia, 2005; Harry, Arnaiz, Klingner, Sturges, 2008). The Stereotype Content Model describes stereotype relationships in terms of an interaction between competence and warmth. Warmth is the more consistent dimension. The nature of competence remains elusive (Fiske, Cuddy, and Glick, 2007; Fiske, Cuddy, Glick, and Xu, 2002). Knowledge of relationships between stereotype groups, which themselves may be effects of bias, could factor into observed competence effects. …

Unsupervised Category Learning With Integral-Dimension Stimuli, Shawn W. Ell, Gregory F. Ashby, Steven B. Hutchinson

Psychology Faculty Scholarship

Despite the recent surge in research on unsupervised category learning, the majority of studies have focused on unconstrained tasks in which no instructions are provided about the underlying category structure. Relatively little research has focused on constrained tasks in which the goal is to learn pre-defined stimulus clusters in the absence of feedback. The few studies that have addressed this issue have focused almost exclusively on stimuli for which it is relatively easy to attend selectively to the component dimensions (i.e., separable dimensions). In the present study, we investigated the ability of participants to learn categories constructed from stimuli for …

The Possible Connection Of Gamma Oscillation And 3-D Object Representation, Thien N. Vu

Summer Research

We process and encode for different features of a particular object (shape, color, texture, etc.) in distinct areas of the brain. How we bind these attributes together into a unified perception of an object is unknown. Past research suggests that synchronized activity between brain areas, particularly induced gamma activity (~ 40 Hz), may account for this binding process and the basis of our conscious perceptual experience, specifically through object representation. In this study, participants were asked to look at a series of 2-D pictures of cars from distinctive rotations (0⁰, 90⁰, 180⁰) and were …

Effect Of Out-Group Exposure On The Mirror Neuron System, Mackenzie Hepker

Summer Research

Mirror neurons appear to play an important role in the experience of empathy, and may be critical for understanding the social signals of others in an interactive context between distinctly identified groups. Research has shown that mirror neuron activation is greater when observing in-group members (others that one most identifies with based on a certain factor or number of factors) as opposed to out-group members, which may implicate the mirror neuron system (MNS) in the neural aspect of social bias. However, no research had been conducted on the effect on the MNS of practice in interpreting and internalizing social signals …

Feeling At Home: Learning, Law, Cognitive Science, And Narrative, Lea B. Vaughn

Articles

What is the "how and why" of law's affinity for narrative? In order to explain why the use of stories is such an effective teaching and presentation strategy in the law, this paper will consider theories and accounts from cognitive as well as evolutionary psychology, neuroscience, and, briefly, cultural anthropology. This account seeks to address "how" narrative helps us learn and use the law as well as "why" we are so compelled to use stories in teaching and in practice.

Brain science, simplified here, suggests that the first task is to grab someone's attention. Emotionally charged events are more likely …
