- Comparing the Cognitive Mechanisms of False Memories with the Misinformation and DRM ParadigmsO'Neill, Meagan (Virginia Tech, 2017-06-16)Many methodologies have been used to generate false memories, with the misinformation (MI) paradigm and the Deese-Roediger-McDermott (DRM) paradigm being the most commonly studied. The MI paradigm generates false memories based on retroactive interference across episodes, while the DRM paradigm generates false memories based on semantic similarities across stimuli. Since current research is ambiguous about whether the processes for different types of false memories are similar, the purpose of this project was to compare the neural mechanisms between MI and DRM false memories. We used a novel paradigm to limit methodological differences, while maintaining the defining characteristics of each paradigm. We made ERP predictions for false memories in both paradigms based on four current cognitive theories of false memories: fuzzy-trace theory, spreading activation/monitoring theory, global matching models, and source of activation confusion (SAC) model. We found no LPC, FN400, or N2 neural differences between the two types of false memories. This result is discussed in the context of the theories and the implications about our understanding of false memories. Our results support that there may not be mechanistic differences in false memory recollection when paradigms to produce the false memories are similar.
- Research Centers as Change Agents: Reshaping Work in Rhetoric and WritingGogan, Brian; Belanger, Kelly R.; Patriarca, Ashley S.; O'Neill, Meagan (National Council of Teachers of English, 2010-12)This article defines research centers as associative enterprises for solving scholarly and societal problems that cannot be adequately addressed by individuals. We identify more than fifty research centers in rhetoric and writing, past and present, and argue that they function as change agents by emphasizing collaboration and conducting research focused on publics.
- Source Memory Failures: Comparing Source Misattribution to Sources of False MemoriesO'Neill, Meagan (Virginia Tech, 2015-04-24)Successful episodic recollection occurs when an event properly binds with its context. Source misattribution demonstrates incorrect binding of a memory with its contextual information. By contrast, false memories are memories of events that did not occur. Although theoretically they should not be bound with contextual information, often, false memories are accompanied by contextual information. This phenomenon is known as content borrowing. This thesis project examined the differences between the two contextual memory errors. The DRM paradigm was used to induce both source misattributions and content borrowing. This allowed the neural differences between the two to be directly tested. No differences were found between source misattribution and content borrowing. However, false memories with content borrowing showed different neural activations from true memory with correct source, true memory with incorrect source, and correct rejection. This suggests that false memories and source misattributions may represent similar errors in memory that rely on gist memory traces.
