An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney
An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney
LSU Master's Theses
Co-speech gesture is an important part of human communication and aids in comprehension, learning, and memory. The addition of iconic gestures to speech has been shown in prior work to enhance memory for the speech. However, it remains unclear as to whether this benefit requires gestures to be meaningful, or, conversely, if any attentionally-engaging gesture will enhance memory. In the current study, we tested two theories to explain the mnemonic benefits of co-speech gesture: Dual Coding Theory, which attributes these benefits to multimodal encoding and enhanced imageability, and Attentional Highlighting Theory, which posits that gestures draw more attention to concurrent …
Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie
Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie
LSU Doctoral Dissertations
The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …
Modeling Melodic Dictation, David John Baker
Modeling Melodic Dictation, David John Baker
LSU Doctoral Dissertations
Melodic dictation is a cognitively demanding process that requires students to hear a melody, then without any access to an external reference, transcribe the melody within a limited time frame. Despite its ubiquity in curricula within School of Music settings, exactly how an individual learns a melody is not well understood. This dissertation aims to fill the gap in the literature between aural skills practitioners and music psychologists in order to reach conclusions that can be applied systematically in pedagogical contexts. In order to do this, I synthesize literature from music theory, music psychology, and music education in order to …
Forget Me Not: Are Stronger Memories More Susceptible To Retrieval-Induced Forgetting?, Laura Lee Heisick
Forget Me Not: Are Stronger Memories More Susceptible To Retrieval-Induced Forgetting?, Laura Lee Heisick
LSU Doctoral Dissertations
Successfully retrieving information sometimes causes forgetting of related, but unpracticed, information, termed retrieval-induced forgetting (RIF). One explanatory mechanism of RIF suggests related, but currently irrelevant, information is inhibited during retrieval, resulting in poorer memory for competing representations. Critically, this perspective suggests stronger memories are more susceptible to RIF because stronger representations produce additional competition when unpracticed. To resolve this competition, strong competing items are inhibited, resulting in the counterintuitive prediction that stronger memories are more likely to be forgotten. The aim of the current experiments was to replicate and extend recent work suggesting non-typical objects and own-race faces, both of …
The Effects Of Emotion And Action On Binding In Memory, Kacie Mennie
The Effects Of Emotion And Action On Binding In Memory, Kacie Mennie
LSU Master's Theses
The ability to successfully bind features and objects at different levels of abstraction is important for everyday functioning of memory. The current study examined how actions and emotional arousal influence item recognition and between-item binding across two experiments. According to the Arousal-Biased Competition Theory (ABC; Mather and Sutherland, 2011), binding can be enhanced by emotional arousal, depending upon what is the focus of attention within a scene. In the current study, participants viewed a series of slides, each of which depicted a person performing an action with an object, as well as an object that is not interacted with. All …
The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira
The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira
LSU Master's Theses
There are different ways of lying and these lies may have different impacts on memory. In this study, participants studied pictures of objects, and later lied and told the truth about these and other objects by describing them or by denying they had seen them. Forty-eight hours later, participants were tested on their source memory. Results revealed that participants had good memory for having falsely described a never-seen object, but poor memory for having falsely denied seeing a studied object. These results suggest that telling certain types of lies may make a person more likely to forget having lied at …
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 …
Intellectual Ability In Children With Anxiety: A Replication And Exploration Of The Differences, Melissa S. Munson
Intellectual Ability In Children With Anxiety: A Replication And Exploration Of The Differences, Melissa S. Munson
LSU Master's Theses
The purpose of this study was to examine the effect of anxiety on the intellectual functioning of children. Specifically, the current researchers sought to replicate previous findings that children with higher levels of anxiety have significantly lower scores on tests of intelligence. A second goal was to examine possible reasons for these deficits, including possible deficits in working memory and/or attention. Participants were divided into two groups with high and low anxiety, based on a self-report measure, though none of the children reported clinically problematic anxiety. The participants were 19 children (10 males, 9 females) who were recruited from the …
Under Construction: Recollecting The Museum Of The Moving Image, AndrÉe Elise Comiskey Betancourt
Under Construction: Recollecting The Museum Of The Moving Image, AndrÉe Elise Comiskey Betancourt
LSU Doctoral Dissertations
On February 27, 2008 the Museum of the Moving Image launched its $65 million renovation and expansion with a digital groundbreaking. Since opening its doors in Astoria, New York in 1988, the museum, originally devoted to film and television, has embraced digital media. From its “Hollywood East” Astoria Studio historic landmark site to its popular website, the Museum of the Moving Image provides a unique setting for studying the museumification of moving image culture, particularly the production and consumption of moving images. In response to the Museum of the Moving Image’s domestication of moving image culture in its core exhibition, …
Apolipoprotein Status And Cognitive Functioning In Adulthood: Role Of Physical Health And Social Network Characteristics, Jennifer Lee Silva
Apolipoprotein Status And Cognitive Functioning In Adulthood: Role Of Physical Health And Social Network Characteristics, Jennifer Lee Silva
LSU Doctoral Dissertations
This study examined the relationships among cognitive function, physical health, social network characteristics, and apolipoprotein (APOE) genotype in participants from the Louisiana Healthy Aging Study. Prior literature has shown that the ε4 allele of APOE is associated with cognitive deficits (Wisdom, Callahan, & Hawkins, 2009). This study failed to find any relation between APOE genotype (ε4 carrier vs. non-carrier) and cognitive ability after controlling for age and education level. Tests for physical health mediation and social network moderation did not alter the ε4/cognition null results. This finding conflicts with prior research suggesting that physical activity and health modify the association …
"Honduran Memories": Identity, Race, Place And Memory In New Orleans, Louisiana, Samantha Euraque
"Honduran Memories": Identity, Race, Place And Memory In New Orleans, Louisiana, Samantha Euraque
LSU Master's Theses
During the decade preceding the height of the civil rights movement, a small population of Hondurans established residence in the New Orleans area. This Honduran migration was largely due to the trade relationship that existed between Honduras and New Orleans. Honduras was also experiencing political unrest and economic instability due to military coups, fruit company strikes and floods during the late 1950s. In response, the advent of the 1960s brought with it the first wave of Hondurans. According to the 2000 Census there were 64,340 people of Hispanic origin in the four parishes included in the New Orleans metropolitan area, …
A Performance Genealogy Of "Etchings Of Debutantes", Melanie A. Kitchens
A Performance Genealogy Of "Etchings Of Debutantes", Melanie A. Kitchens
LSU Master's Theses
In this thesis history performs that which Della Pollock terms “historicity” in her “Introduction” to Exceptional Spaces: Essays in Performance and History. History as historicity is no longer an evolutionary master narrative that dictates essential Truths. Rather, it is a site for performance where unfinalized and partial fragments of the past cluster into stories that mingle fact and fiction. Historicity defines a space or an event where history is a doing. The performer of this history embraces agency, which she uses to place herself within history rather than dominate or be dominated by it. Observing history as historicity, Joseph Roaches …
The Body Politic: Burial And Post-War Reconciliation In Baton Rouge, Leah Wood Jewett
The Body Politic: Burial And Post-War Reconciliation In Baton Rouge, Leah Wood Jewett
LSU Master's Theses
Historians typically agree that reconciliation between the white North and South took place between the period of 1898 (Spanish-American War) and 1913 (before World War I). To test this hypothesis and identify when reconciliation took place in Baton Rouge, Louisiana, I will use the burial of R. L. Pruyn in the Baton Rouge National Cemetery. Pruyn served as a U.S. soldier during the Mexican War and a Confederate soldier during the Civil War. Anthropologists have studied rituals, beliefs, and practices associated with death since early in the discipline. Archaeologists, in particular, have focused on this aspect of culture, in large …
Relationship Between Neuropsychological Deficits And Cerebral Perfusion Abnormalities In Cocaine Abusers, Karen A. Tucker
Relationship Between Neuropsychological Deficits And Cerebral Perfusion Abnormalities In Cocaine Abusers, Karen A. Tucker
LSU Doctoral Dissertations
The purpose of this study was to investigate the relationships between the severity of cocaine/alcohol use, neuropsychological functioning, and cerebral blood flow abnormalities. Cocaine users (n = 60) and control subjects (n = 13) were administered a battery of neuropsychological tests that yielded the following factors: Attention/Executive Functioning, Memory, Simple Motor, and Sensorimotor. Participants were assessed for decreased cerebral blood flow with single-photon emission computed tomography (SPECT). Examination of group differences indicated that cocaine users performed significantly worse than controls on the Memory and Sensorimotor factors. The frequency/duration of cocaine use, alcohol use, and a combination of both substances were …
