The Effects Of Divided Attention In Free Recall: Affecting Trace Accumulation By Dividing Attention, Anne Olsen
The Effects Of Divided Attention In Free Recall: Affecting Trace Accumulation By Dividing Attention, Anne Olsen
USF Tampa Graduate Theses and Dissertations
How environmental information stores in memory directly affects our ability to retrieve the information. This thesis investigates the effects that dividing attention during study has on the storage of contextual information. Through several experiments, participants were asked to study and later recall word lists using a mixed-pure design with strengtheners varying as either repetition or study time. Experiment 1 investigates the effects of divided attention on the formation of inter-item associations and Experiments 2-6 manipulate strengthening item and context information in a memory trace when cognitive load is strained at various levels. Experimental results indicated that dividing attention during study …
Temporal And Spatial Properties Of Orientation Summary Statistic Representations, Jacob S. Zepp
Temporal And Spatial Properties Of Orientation Summary Statistic Representations, Jacob S. Zepp
USF Tampa Graduate Theses and Dissertations
The aim of the current work was to determine the amount of information that contributes to the formation of summary statistical representations (SSRs), as well as the time course over which these representations are formed. While the prevailing interpretation of SSRs within literature is that the summaries are formed through a compulsory rapid integration across all information in a scene, debate exists on the necessity of this unique processing mode. To investigate the formation of SSRs, two experiments were conducted. In the first, results from an orientation averaging task were compared to results from a whole-report task, over equivalent stimulus …
Emotional Memory For Affective Words In Manifest And Prodromal Huntington’S Disease, Patricia Lynn Johnson
Emotional Memory For Affective Words In Manifest And Prodromal Huntington’S Disease, Patricia Lynn Johnson
USF Tampa Graduate Theses and Dissertations
Huntington’s disease (HD) patients have been found to have specific deficits in emotional processing, most consistently demonstrating impairment recognizing the emotion expressed on a static face. The purpose of this study was to examine emotional memory in HD, which has not yet been investigated, and its relationship with executive functioning, emotional facial recognition, and the disease progression in HD. An emotional memory task with pleasant, neural, and unpleasant words was administered to control (n=26), prodromal HD (n=26), and manifest HD (n=29) participants in addition to executive function measures, an apathy scale, and emotional facial recognition task. Free recall was not …
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 …
