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 …
The Relationships Among Emotion, Cognitive Dysfunction And Anosognosia In Huntington’S Disease, Danielle C. Hergert
The Relationships Among Emotion, Cognitive Dysfunction And Anosognosia In Huntington’S Disease, Danielle C. Hergert
USF Tampa Graduate Theses and Dissertations
Huntington's disease (HD) is a genetic, neurodegenerative disorder that is characterized by motor, cognitive and psychiatric disturbances. Anosognosia, or lack of awareness of symptoms, is commonly observed in neurodegenerative disorders, including HD. Most theories suggest that emotion, executive functioning, and memory play important roles in self-awareness. There is limited research of anosognosia in HD and no theoretical model of how it manifests in the disease. The purpose of this study was to examine Metacognitive Knowledge, or overall beliefs about the self, and Online Awareness, or the ability to predict (Anticipatory Awareness) and evaluate (Emergent Awareness) task performance, in …
Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry
Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry
USF Tampa Graduate Theses and Dissertations
According the linguistic relativity hypothesis, the language one speaks affects how one thinks. Because languages differ in how they categorize color, linguistic relativity has often been tested by conducting experiments on color perception and memory. This study examines the linguistic relativity hypothesis using ecologically valid stimuli: pictures of eyes. Because Russian-speakers are more likely to describe blue/grey eyes as grey, whereas English speakers are more likely to describe them as blue, English and Russian participants were asked to match the overall color of blue eyes to a color scale. There were three conditions. In the first condition (perception), participants saw …

Recognition memory accuracy is harmed by prior testing (a.k.a., output interference [OI]; Tulving & Arbuckle, 1966). In several experiments, we interpolated various tasks between recognition test trials. The stimuli and the tasks were more similar (lexical decision [LD] of words and nonwords) or less similar (gender identification of male and female faces) to the stimuli and task used in recognition testing. Not only did the similarity between the interpolated and recognition tasks not affect recognition accuracy but performance of the interpolated task caused no interference in subsequent recognition testing. Only the addition of recognition trials caused OI. When we presented …
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 …
