The Neural Correlates Of Retrospective Memory Monitoring: Convergent Findings From Erp And Fmri, Jeremy Clark Roper Jul 2011

The Neural Correlates Of Retrospective Memory Monitoring: Convergent Findings From Erp And Fmri, Jeremy Clark Roper

Theses and Dissertations

Monitoring the accuracy of memory is an automatic but essential process of memory encoding and retrieval. Retrospective memory confidence judgments are making effective and efficient decisions based on one's memories. The neural processes involved in retrospective confidence ratings were investigated with EEG and fMRI using a recognition memory task designed such that participants also rated their confidence in their memory response. Correct trials (hits and correct rejections) were examined for differences related to the participants' level of confidence in their response. There were significant differences in electrophysiological activity (in the FN400 and the late parietal component) associated with confidence ...


Essential Oils Peppermint And Rosemary Exposed To The Olfactory Sense And The Effects On Cognition And Perceived Mood, Tara A. Ricciardelli Jun 2011

Essential Oils Peppermint And Rosemary Exposed To The Olfactory Sense And The Effects On Cognition And Perceived Mood, Tara A. Ricciardelli

Undergraduate Theses and Capstone Projects

Recent research suggests that essential oils of a certain quality can enhance memory consolidation and cognitive performance. The present study examined whether the essential oils rosemary and peppermint were powerful enough to significantly improve short-term memory in recall and recognition tasks. Participants were in a room with a device that diffused a scent or water (no scent) for ten minutes prior to their entry. The participants viewed word lists and were later tested for accuracy in terms of recall and recognition. Results from a one-way analyses of variance demonstrated that peppermint and rosemary did not significantly improve short-term memory or ...


The Role Of Epac Signaling In Memory Consolidation And Sleep Deprivation, Nan Ma Jan 2011

The Role Of Epac Signaling In Memory Consolidation And Sleep Deprivation, Nan Ma

Publicly Accessible Penn Dissertations

It is well established that cAMP signaling within neurons plays a major role in the formation of long-term memories. cAMP has three targets, protein kinase A (PKA), hyperpolarization-activated cyclic nucleotide-modulated (HCN) channels, and exchange protein activated by cAMP (Epac). Studies have revealed that both PKA and HCN channels are important for long-term memory formation. However, little is known about the role of Epac in this process. Epac is a cAMP- dependent guanine nucleotide exchange factor for the small G proteins including Rap1.The Epac2 isoform is highly expressed in the forebrain. This dissertation examines the role of Epac in memory ...


Initial Testing Reduces Eyewitness Suggestibility For Faces, Jessica Ann Lapaglia Jan 2011

Initial Testing Reduces Eyewitness Suggestibility For Faces, Jessica Ann Lapaglia

Graduate Theses and Dissertations

Past research has demonstrated that verbally recalling the appearance of a perpetrator after witnessing a crime can hinder one's ability to identify that perpetrator in a subsequent lineup (verbal overshadowing; Schooler & Engstler-Schooler, 1990). A recent study by Chan, Thomas, and Bulevich (2009) revealed that taking an initial memory test for an event increases one's susceptibility to later misleading information. These findings contradict those from the testing effect literature, which indicate that initial testing should enhance memory performance (Roediger & Karpicke, 2006). In the current study I investigated the effects of verbally describing a face on eyewitness suggestibility to later ...


Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins Jan 2011

Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins

LSU Master's Theses

Researchers have found fear to impact a variety of cognitive variables in individuals with specific phobia. Attentional bias is a cognitive variable that has received considerable attention in the specific phobia literature; however, the existing literature follows only one line of attentional bias—bias as encoded through images, words, or other content presented visually. This study aimed to expand on this area by assessing attention and cerebral laterality in individuals with specific phobia using a dichotic listening paradigm (i.e., via auditory means). Results indicated that participants with specific phobias do not significantly differ from controls in terms of the ...


Adaptive Memory And Social Influences, Aaron D. Leedy Jan 2011

Adaptive Memory And Social Influences, Aaron D. Leedy

UNF Graduate Theses and Dissertations

Recently, cognitive psychologists have focused their research on the survival aspects of human memory, showing advantages for remembering information encoded for adaptive qualities. When participants rated words related to survival relevance (stranded in grasslands), Nairne et al. (2007) and others found survival processing’s retention superior to many semantic encoding techniques, however, we questioned the global application of survival processing. In the present adaptive memory experiment we used the thematic word list paradigm pioneered by Deese, Rodeiger and McDermott, allowing us to measure false recall of critical items from sets of word lists. To investigate recall differences based on the ...
