Attention to Suffering in the Work of Simone Weil and Käthe Kollwitz
(2018)This dissertation traces the ethical and conceptual connections between Weil’s account of attention and Kollwitz’s artistic practice of attention, especially attention to suffering. Attention, in Weil’s view, is a strenuous ... -
Determinants of Distractibility in the Rhesus Macaque
(2013)The visual world is full of potentially important information, but only a subset of the world can be evaluated at any time. An essential function of the central nervous system is to rapidly and adaptively select which stimuli ... -
Effects of Expectation, Experience, and Environment on Visual Search
(2009)A pervasive aspect of daily life is searching for a specific target amongst an array of distracting items. Studying such visual searches offers a useful and powerful tool for revealing the underlying aspects of visual attention. ... -
Frontoparietal activation during visual conjunction search: Effects of bottom-up guidance and adult age.
(Hum Brain Mapp, 2017-04)We conducted functional magnetic resonance imaging (fMRI) with a visual search paradigm to test the hypothesis that aging is associated with increased frontoparietal involvement in both target detection and bottom-up attentional ... -
Improvement in visual search with practice: mapping learning-related changes in neurocognitive stages of processing.
(J Neurosci, 2015-04-01)Practice can improve performance on visual search tasks; the neural mechanisms underlying such improvements, however, are not clear. Response time typically shortens with practice, but which components of the stimulus-response ... -
Inhibition-Induced Forgetting Results from Resource Competition between Response Inhibition and Memory Encoding Processes.
(J Neurosci, 2015-08-26)UNLABELLED: Response inhibition is a key component of executive control, but its relation to other cognitive processes is not well understood. We recently documented the "inhibition-induced forgetting effect": no-go cues ... -
Investigating the Effects of Fantasy Proneness and Instructions to Fantasize
(2011)Fantasy prone individuals spend much of their time fantasizing, focusing on a rich internal world of imaginary people or stories, vivid memories, or dreams. Fantasy proneness has been linked to psychological distress and ... -
Investigations into the Neural Basis of Consciousness
(2019)The overarching goal of this dissertation was to improve our understanding of the neural basis of consciousness by approaching the problem along two separate, complementary facets: examining the levels of consciousness and ... -
Task-related changes in degree centrality and local coherence of the posterior cingulate cortex after major cardiac surgery in older adults.
(Hum Brain Mapp, 2017-11-21)OBJECTIVES: Older adults often display postoperative cognitive decline (POCD) after surgery, yet it is unclear to what extent functional connectivity (FC) alterations may underlie these deficits. We examined for postoperative ... -
The Neurophysiology of Social Decision Making
(2010)The ultimate goal of the nervous systems of all animals is conceptually simple: Manipulate the external environment to maximize one's own survival and reproduction. The myriad means animals employ in pursuit of this goal ...
