Affective and Cognitive Processing in Nonsuicidal Self-Injury
(2014-02-25)
Nonsuicidal self-injury (NSSI) is a behavior recently added to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a condition for further study. In this dissertation, I present findings from three studies ...
Simulating personal future events: Contributions from episodic memory and beyond
(2014-02-25)
Episodic simulation refers to the construction of imagined, hypothetical events that might occur in one's personal future. Damage to our capacity for episodic simulation can produce grave consequences, impairing our ability ...
High-level neural structures constrain visual behavior
(2014-06-06)
Visual cognition is notoriously limited: only a finite amount of information can be fully processed at a given instant. What is the source of these limitations? Here, we suggest that the organization of higher-level visual ...
Do Yourself a Favor: We Help Our Future Selves for the Same Reasons We Help Others
(2014-06-06)
As humans we have a remarkable capacity to sacrifice for the future, and an equally remarkable capacity to shortchange it, leaving our future selves to pay the price. The research in this dissertation suggests that sacrifice ...
Measuring, monitoring, and maintaining memories in a partially observable mind
(2014-06-06)
Visual memory holds in mind details of objects, textures, faces, and scenes. After initial exposure to an image, however, visual memories rapidly degrade because they are transferred from iconic memory, a high-capacity ...
Society in Mind: The manifestation of structural power and status differences in cognitive and regulatory domains.
(2014-06-06)
Where one stands in society matters for how one feels, thinks, and behaves. This dissertation provides evidence for this claim from the perspective of universal psychological mechanisms used to navigate the social world. ...
Profiles of Everyday Thought Suppression
(2014-06-06)
The present research assessed whether levels of depression, anxiety and worry, obsessive-compulsive distress, and psychopathy were differentially related to distinct thought suppression profiles. As a means to achieving ...
Cognitive Control of Emotional Information in Schizophrenia: Understanding the Mechanisms of Social Functioning Impairments
(2013-10-18)
Social functioning impairments are a core, debilitating, and treatment refractory feature of schizophrenia. The mechanisms contributing to these impairments are unknown. Cognitive control mechanisms, mediated by the lateral ...
Large-Scale Networks in the Human Brain revealed by Functional Connectivity MRI
(2013-10-18)
The human brain is composed of distributed networks that connect a disproportionately large neocortex to the brainstem, cerebellum and other subcortical structures. New methods for analyzing non-invasive imaging data have ...
A Social Neuroscience Perspective on Egocentric Influence
(2014-06-06)
This dissertation explores the cognitive mechanisms and motivations that guide two aspects of human social behavior: thinking about other's experiences and communicating with others. In both cases, studies investigated the ...
