Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones
Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones
Master's Theses
All mammalian females undergo behavioral and neurological changes during pregnancy and motherhood. Many of these changes lead to an enhanced ability to be an effective mother including: increased memory, foraging behaviors, and boldness. Here, we examined the differences in rehearsal strategies between mother and virgin rats. Stops made by rats when exploring their environment have been found to result in reverse replay activity in the hippocampus (Foster & Wilson, 2006). Reverse replay is sequential replay that occurs in the hippocampus immediately after a spatial experience; this replay/activation is in reversed order of the initial spatial episode (Foster & Wilson, 2006). …
Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas
Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas
Master's Theses
The female rat, among other species, undergoes a fundamental brain re-modeling as a consequence of experiencing the normal and natural events of pregnancy and offspring stimulation. Compelling data show that maternal experiences produce neurobiological modifications in the female leading to specific maternal behaviors, affective states, and the basic underlying female neurobiology necessary to raise viable offspring. This study aims to evaluate the number, quality and selective activation of neurons that develop during the maternal experience. The study showed a trend toward supporting the hypothesis that a “maternal-circuit” is formed through the proliferation of neurons during late-motherhood and lactation, and is …
Visual Discrimination Training For Rats : Developing A New Methodology To Explore Laterality Differences, Tiffany R. Brunelli
Visual Discrimination Training For Rats : Developing A New Methodology To Explore Laterality Differences, Tiffany R. Brunelli
Honors Theses
The goal of this study was to examine right hemisphere specialization for faces at the neuronal level. Research has shown that facial recognition relies on the right anterior temporal lobe and involves integrating multiple features (Bukach, Gauthier, & Tarr, 2006). Evidence from rat studies confirms that the anterior temporal lobe is involved in integrating multiple object features (Eacott, Machin, & Gaffan, 2001). However, these studies did not examine differences between the brain’s right and left hemispheres. It was hypothesized that the right anterior temporal lobe is more important for feature integration. The current study aimed to develop a methodology for …
Can She Ever Be "The Man"? : The Effect Of Gender On Implicit Perceptions Of Leadership Ability In An Applied Hiring Task, Rebecca S. Frazier
Can She Ever Be "The Man"? : The Effect Of Gender On Implicit Perceptions Of Leadership Ability In An Applied Hiring Task, Rebecca S. Frazier
Honors Theses
Despite numerous advances in the eld of women's rights and a general decline in explicit discrimination, there still exists a dramatic lack of women in leadership positions across America. This research seeks to expand upon past studies suggesting that there is a basic cognitive incongruency between traditional male and leadership roles which leads ordinarily "unbiased" individuals to perceive women as less suited r leadership positions than men. Thus, this experiment investigates the implicit biases against women leaders by asking if the subtle addition of gender information alters individuals' initial impressions of leadership capability in an applied hiring task involving resumes, …
Motivation To Lead : Investigating The Power Of The Mtl Equation, Elizabeth Robinson
Motivation To Lead : Investigating The Power Of The Mtl Equation, Elizabeth Robinson
Honors Theses
Recent research has investigated a measurable way to determine an individual's motivation to lead in social situations by looking at specific aspects of an individual that make up his/her leadership ability and experience. The MTL (Motivation to Lead) construct is referred to as an individual differences construct that measures a person's motivation to acquire a leadership position based on specific personality traits and values (Chan & Drasgow, 2002). Chan and Drasgow's findings suggest that specific antecedents have calculable correlations to the three types of motivation to lead: Affective/Identity MTL, Non-Calculative MTL, and Social-Normative MTL. For example, Chan and Drasgow reported …
Size Of Food Packaging And Cognitive Performance, Shannon Henry
Size Of Food Packaging And Cognitive Performance, Shannon Henry
Honors Theses
Many factors have been shown to affect individuals' cognitive performance, such as sleepiness, hunger, motivation, etc. One such factor that has recently gained much attention is self-regulation, or one's ability to control, regulate, or change his or her behaviors. In lay terms, self-regulation may be thought of more or less as self-control. Together, this researchon self-regulation suggests that it is a limited resource, which, when depleted in one area, reduces self-regulationability across other areas. Many past studies regarding self-regulation have incorporated food as a way to deplete self-regulation. In particular, the size of food packaging may be a way to …
