Exploring Parental Experiences And Decision-Making Processes Following A Fetal Anomaly Diagnosis, Ramona L. Fernandez May 2013

Exploring Parental Experiences And Decision-Making Processes Following A Fetal Anomaly Diagnosis, Ramona L. Fernandez

Electronic Thesis and Dissertation Repository

Often the first indication that something may be wrong in a seemingly normal pregnancy occurs during the first detailed ultrasound appointment between 16 and 20 weeks gestation. Even the most tentative suspicions of fetal anomalies is jarring. Parent’s default reality of a normal pregnancy and a ‘perfect child’ changes to one of risk factors and the possibility of an ‘unhealthy child’. This study begins with the realization of this first loss in a series of losses that follow for parents as they grapple with diagnostic information to be able to make informed medical decisions regarding their fetus and pregnancy ...


The Neural Representation Of Value And Individual Differences In Human Intertemporal Choice, Nicole Cooper Jan 2013

The Neural Representation Of Value And Individual Differences In Human Intertemporal Choice, Nicole Cooper

Publicly Accessible Penn Dissertations

Intertemporal choices, or decisions that involve tradeoffs between rewards and time, are ubiquitous in our daily lives. The tendency to devalue, or discount, future rewards has been linked to maladaptive long-term health and financial outcomes. Despite their broad clinical relevance, individual differences in discounting preferences are poorly understood. In this thesis, we make progress on the understanding of the neural basis of these decisions and factors that affect individual differences. The first two chapters focus on neurobiology. Chapter 2 investigates the decision-related variables that best explain the observed patterns of BOLD activity in ventromedial prefrontal cortex (VMPFC) and ventral striatum ...


Assessing Naturalistic Decision Making By Experienced And Inexperienced Interrogators In High Stakes Interviews, Amy Bethany Ross Jan 2013

Assessing Naturalistic Decision Making By Experienced And Inexperienced Interrogators In High Stakes Interviews, Amy Bethany Ross

Open Access Theses & Dissertations

The current thesis aimed to improve the ecological validity of human intelligence interrogation research. Although field practitioners and researchers have worked together to improve the scientific validity and practical execution of interrogation techniques, research has yet to understand how, when and why interrogators implement such techniques. This thesis investigated the active decision making processes of interrogators that occur during high value interrogations. The theory of Naturalistic Decision Making was used to capture the naturalistic characteristics of high value interrogations- ambiguity, time pressure and high stakes. To capture the decision-making processes that are associated with skilled performance, this research conducted in-depth ...
