Rethinking Attention Control: An Individual Differences Approach, Vincent A. Medina
Rethinking Attention Control: An Individual Differences Approach, Vincent A. Medina
LSU Doctoral Dissertations
While there is extensive literature on visual spatial attention, less is known about auditory spatial attention, especially in terms of attention control. There is also a growing literature highlighting the importance of considering individual differences in attention control ability. Given these points, the purpose of this study was twofold. The first was to understand how auditory attention control is influenced by spatial location as well as vision. The second was to examine whether individual differences in attention control ability can predict task performance in that context. We utilized two tasks for these purposes. Experiment 1a consisted of a cross-modal Stroop …

Previous Experiences Drive Attention, Sunghyun Kim
LSU Doctoral Dissertations
Traditionally, the allocation of attention was understood within goal-driven and stimulus-driven factors. However, the traditional approach cannot fully account for the mechanism of attentional orienting. Instead, a growing body of evidence shows that previous search experiences, irrelevant to both goal-driven and stimulus-driven factors, influence attentional allocation. For example, when contexts predict information of targets, the contexts guide attention toward the stimuli having the information predicted by the contexts: contextual cueing. In addition, more valuable stimuli attract more attention: value-driven attentional capture. However, two critical issues are present. First, contextual cueing has been found largely when the contexts and the target …
Leveling The Viewing Field: The Impact Of Target Prevalence On Searcher's Functional Viewing Field, Juan D. Guevara Pinto
Leveling The Viewing Field: The Impact Of Target Prevalence On Searcher's Functional Viewing Field, Juan D. Guevara Pinto
LSU Doctoral Dissertations
It is well known that target prevalence impacts various cognitive processes. In visual search, rare search targets are more difficult to detect than common targets. The present research investigated novel questions about target prevalence, focusing on observers’ functional viewing field (FVF) during passive search tasks. The FVF is the area in a display where attention is focused and item processing is enhanced. According the FVF framework (Hulleman & Olivers, 2017), the size of the FVF is modulated by the ease of target detections, such that visual search involving difficult target detection reduces the FVF. Although this would suggest that low …
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 …
