Proximity, Touching, And Testosterone: An Observational Study Of Mate Retention Tactics In Humans, Kraig Shattuck
Wayne State University Dissertations
Mate guarding behaviors are strongly selected for in species that suffer from infidelity and cuckoldry. Two forms of mate guarding behaviors that have been found in self-report studies on humans are proximity and touching. Proximity actively prevents infidelity though the physical act of being present. Touching indirectly prevents infidelity by signaling to any potential rivals that their partner is taken, as well as signaling to the partner that they are being watched. Testosterone is a hormone implicated in competition and aggression. When in the presence of a potential rival, testosterone levels tend to increase. This increase should be related to …

Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang
Wayne State University Dissertations
The ability to remember past events is critical for everyday life and showed robust improvement over development from childhood to adulthood. With advances in noninvasive neuroimaging methods such as functional MRI in recent years, research efforts have been focused on identifying neural correlates underpinning developmental gains in memory performance. In my dissertation work, using a widely-validated subsequent memory paradigm, I aim to characterize functional MRI correlates of memory development. Specifically, I focused my investigation on identifying age differences in the functional patterns of two brain regions critical for memory, the prefrontal cortex and the hippocampus. Focusing on the prefrontal cortex …

The Protective Role Of Parenting Behaviors In The Development Of African American Adolescents, Kelsey Johanna Sala-Hamrick
Wayne State University Dissertations
This dissertation aimed to understand how African American parents protect their teens from developing psychopathology in the face of extreme adversity. To do this, I examined three dimensions of parenting behavior, stress exposure, and behavior problems in order to understand the direct and moderating relations between parenting behaviors, cumulative stress and youth internalizing, externalizing, and total psychological problems. 150 African American primary caregivers reported on their adolescent children’s internalizing, externalizing and total behavior problems, exposure to stressful events, and their own parenting behavior. 150 inner-city African American adolescents reported on their exposure to traumatic stressors and a subsample of 43 …
