Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp
Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp
LSU Doctoral Dissertations
Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …
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 …
An Examination Of The Effects Of Post-Identification Feedback On Jurors, Daniella Cash
An Examination Of The Effects Of Post-Identification Feedback On Jurors, Daniella Cash
LSU Doctoral Dissertations
Post-identification feedback (PIF) occurs when witnesses are given feedback following their identification choices. This feedback has been shown to alter witnesses’ retrospective judgments regarding their witnessing experience (e.g., they are more confident that they made a correct identification). PIF effects are robust; they impact witnesses’ memory of their experience, and also appear to act as confirmation to jurors who are asked to assess witness reliability. A current recommendation for eyewitness procedures is that identifications should be recorded and shown to jurors at trial, but this might be harmful if jurors are also negatively impacted by this suggestive feedback. The goal …
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 …
Examining Successful Aging And Resilience After Disasters, Katie Elizabeth Stanko
Examining Successful Aging And Resilience After Disasters, Katie Elizabeth Stanko
LSU Doctoral Dissertations
Resilience, a psychological adaptive process and outcome, is the ability to return to normal functioning after a traumatic event, such as a natural disaster. Successful aging entails biological, psychological, and social factors. The Great Flood of 2016 in the greater Baton Rouge area caused catastrophic structural damage to thousands of homes and businesses. Some of these individuals had previously moved to the Baton Rouge area after receiving catastrophic damage during Hurricane Katrina in 2005. In this study, I investigated the role that age group (younger, middle-aged, older) and disaster exposure group (control, single exposure, double exposure) had on post-disaster well-being. …
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 Mechanism Of Directed Forgetting In Visual Working Memory, Katherine Camille Moen
The Mechanism Of Directed Forgetting In Visual Working Memory, Katherine Camille Moen
LSU Doctoral Dissertations
The goal of the current study was to determine if forgetting in visual working memory (VWM) depends on the strength of the memory representations, and to examine different potential mechanisms of directed forgetting in VWM. The strength of memory representations varies depending on factors during encoding and maintenance, which may impact the likelihood of successful forgetting. Experiment 1 manipulated encoding time and cue onset, and utilized eye tracking in order to determine the extent of directed forgetting in VWM. Results support evidence for partial forgetting, and revealed that the strength of memory representations does not impact the likelihood of successful …
Experimentally Examining The Proposed Relationships Among “Rehearsal-Based” Effects, Corey Ian Mcgill
Experimentally Examining The Proposed Relationships Among “Rehearsal-Based” Effects, Corey Ian Mcgill
LSU Doctoral Dissertations
Despite the importance of rehearsal to most models of verbal working memory, its role has been recently called into question. Much prior work in support of rehearsal models has centered on the experimental effects of word-length, phonological-similarity, and irrelevant sound on serial order recall performance and the interaction of all three with concurrent articulation. However, recent research has suggested that confounding effects of stimuli, such as orthographic neighborhood, may be the true cause of the word-length effect. While these findings alone have significant implications for modern models of rehearsal, to understand them within the context of modern theories of working …
