Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske
Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske
USF Tampa Graduate Theses and Dissertations
The contextual cueing effect was initially thought to be the product of memory guiding attention to the target location. However, the steep search slopes obtained in contextual cueing indicate an absence of attentional guidance. We hypothesized that crowding could be obscuring the presence of attentional guidance and investigated this possibility in 2 experiments. Crowding was manipulated by varying the density of items in the local target region in a contextual cueing task. We observed a significant reduction in search slopes between the novel and repeated conditions when crowding was reduced. Enhancing crowding eliminated the contextual cueing effect. These findings suggest …
The Neural Correlates Of Retrospective Memory Monitoring: Convergent Findings From Erp And Fmri, Jeremy Clark Roper
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 rating, …
Essential Oils Peppermint And Rosemary Exposed To The Olfactory Sense And The Effects On Cognition And Perceived Mood, Tara A. Ricciardelli
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 …

Nonverbal memory focuses on the remembrance of information that cannot be described or put into a verbal component, such as remembering a person's face, identifying abstract stimuli, or remembering objects. Because nonverbal memory focuses on the remembrance of things that cannot be put into words it is a difficult construct to measure accurately. One area that is of great importance in the assessment of nonverbal abilities is spatial memory (Reynolds & Coress, 2007, Foster, Drago, & Harrison, 2009). Most of the tasks that have been developed to assess this construct employ verbally mediated clues allowing the examinee to compensate for …
Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins
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 number of …
