Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy Dec 2017

Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy

University of New Orleans Theses and Dissertations

The model of basal ganglia function proposed by Albin, Young and Penney (1989) describes two anatomically independent motor pathways, the direct and indirect. However, under normal conditions striatal dopamine (DA) is required for the expression of motor behavior, and DAergic control of the two pathways (via D1 and D2 receptors, respectively) is dependent on co-activation. We tested for a possible breakdown of D1/D2 synergism using transgenic R6/1 mice bearing the human huntingtin allele (Htt). Motor stereotypy, observed prior to the onset of HD-related symptoms, was rated on a 5-point scale following activation of: A) D1 receptors alone, B) D2 receptors …


Individual Differences In Adolescents’ Driving Practice During The Learner Stage, Yinan Zhao May 2016

Individual Differences In Adolescents’ Driving Practice During The Learner Stage, Yinan Zhao

University of New Orleans Theses and Dissertations

The implementation of Graduated Driver Licensing (GDL) policies has reduced the rate of car crashes among adolescents. However, limited research has focused on adolescents’ supervised driving during the learner permit stage of GDL. The study aimed to describe supervised driving practice during the learner permit stage and to test predictors of individual differences in the amount and the quality of supervised driving. 183 adolescents (M age = 16.4 years, 54.1% female) and their parents (84.1% mothers) participated. Adolescents reported driving an average of 25 minutes per day. Adolescents living in single-parent households, with less family income, and with a …


The Association Between Hostile Attribution Bias, Social Intelligence, And Relational Aggression In Detained Boys, Gregory M. Fassnacht Dec 2013

The Association Between Hostile Attribution Bias, Social Intelligence, And Relational Aggression In Detained Boys, Gregory M. Fassnacht

University of New Orleans Theses and Dissertations

Research on factors that contribute to the forms and functions of aggression (reactive, proactive, relational, and overt) is important for informing intervention efforts with aggressive youth. Previous research shows that aggressive youth often have cognitive and social deficits associated with their aggressive behavior. For example, aggressive youth may exhibit deficits in social variables such as social intelligence (i.e., the understanding of behaviors of people and ability to predict outcomes of situations). Hypothetically, this lack of social intelligence may be related to how youth interpret social situations, and could conceivably lead to hostile attributional bias, or the tendency to interpret ambiguous …


Anxiety Sensitivity And Its Association With Parenting Behaviors, Rebecca Graham Dec 2013

Anxiety Sensitivity And Its Association With Parenting Behaviors, Rebecca Graham

University of New Orleans Theses and Dissertations

The aim of this study was to examine the association between parent and child anxiety sensitivity in the context of parenting behaviors, specifically by testing parenting behaviors as moderators or mediators of the association between parent and child anxiety sensitivity. Past research implies that parent anxiety sensitivity may be more related to child anxiety sensitivity (moderation) in girls and in the context of certain parenting. Alternatively, parenting behaviors may better account for the association (mediate) between parent and child anxiety sensitivity. To test the hypotheses 191 families (n = 255 youth aged 6-17 and their parents) completed measures of …
