"Paper Sack Brown" : Effects Of Age, Skin Tone, And Stereotype Threat On Cognitive Performance And Self-Efficacy Among African Americans, Breonte Stephan Guy
Master's Theses
Divergent African American skin tones have led to negative stereotypes and outcomes regarding darker-skinned African Americans in many domains, including educational and occupational (Hill, 2002). This study assessed the effects of skin tone and stereotype threat (Steele and Aronson, 1995; Steele, 1997) on cognition in younger and older African Americans. A 2(Skin Tone: light, dark) X 2(Age: young, old) X 2(Stereotype Threat: Threat, Non-Threat) between subjects design was used. Seventy-four African American adults ranging in age from 18 to 86 years completed a battery of cognitive measures. Darker-skinned adults performed more poorly on three tests of intelligence, a paired-associates memory …
The Presence Of Pups After Birth : Effects On Spatial Memory And The Pre-Synaptic Protein Synaptophysin, Abbe Hoffman Macbeth
The Presence Of Pups After Birth : Effects On Spatial Memory And The Pre-Synaptic Protein Synaptophysin, Abbe Hoffman Macbeth
Master's Theses
A newly maternal rat goes through many changes when she gives birth, mostly due to prolonged elevation of hormones, particularly estrogen. Estrogen has been shown to increase memory capabilities by increasing synaptic activity in the CA1 hippocampus, but exactly how is still unknown. The current project uses reproductive experience to determine whether high hormone levels experienced during pregnancy and lactation affect spatial memory and synaptophysin, a pre-synaptic protein that controls vesicle exocytosis and thus may be responsible for enhanced synaptic connectivity. We found that reproduction itself does not affect memory of a spatial task, but the presence of pups has …
Brain-Derived Neurotrophic Factor And Maternal Behavior : Neuronal Alterations In The Medial Preoptic Area And Suppression Of Pup Attacks, Lillian Flores Stevens
Brain-Derived Neurotrophic Factor And Maternal Behavior : Neuronal Alterations In The Medial Preoptic Area And Suppression Of Pup Attacks, Lillian Flores Stevens
Master's Theses
Brain-derived neurotrophic factor (BDNF), by virtue of its relationship to various neurotransmitter systems, hormones, and to estrogen in particular, may play a role in maternal behavior. To explore this possible role, female virgin Sprague Dawley rats received continuous intracerebroventricular infusions ofBDNF sense oligonucleotide and were exposed to pups for maternal behavior testing. Behaviorally, BDNF sense had no effect on maternal behavior but did significantly suppress pup attacks during the first 24 hours of exposure. BDNF had a significant effect on neuronal morphology in the medial preoptic area (mPOA) as well, such that neurons in this region exposed to BDNF had …
Adviser Awareness Of The Kansas Student Publication Act (1992), Latisha D. Haag
Adviser Awareness Of The Kansas Student Publication Act (1992), Latisha D. Haag
Master's Theses
This thesis was a descriptive study examining adviser awareness of the Kansas Student Publication Act (1992) as reported by advisers who were members of the Kansas Scholastic Press Association during the academic year 2002-2003. Because there were no studies prior to the passing of the Act, there was no base line study to determine whether the Act has had an impact since its passing. For this study, 216 advisors, the complete membership of the Kansas Scholastic Press Association, were either given a cover letter explaining the questionnaire and questionnaire at one of the fall conferences, or mailed a cover letter …
