Does Chronic Stress Accelerate Late-Aging Cognitive Decline In Memory And Executive Functioning?, Diane Robinson
Does Chronic Stress Accelerate Late-Aging Cognitive Decline In Memory And Executive Functioning?, Diane Robinson
Electronic Theses and Dissertations
Few studies exist examining the relationship between self-reported stress and cognitive function in healthy nonpsychiatric older adults, and even less studies have examined whether high levels of self-reported stress accelerate the cognitive decline found in normal late-aging populations. A group of older nonpsychiatric adults, ages 54 years and above, were asked to complete three measures assessing their self-perceived stress over the past month, past year, and their lifetime. Sixty-one adults between the ages of 54 and 88 (52% female) participated in a second phase in which neuropsychological tasks were administered to assess three cognitive domains; memory, learning, and executive functioning. …
Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver
Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver
Electronic Theses and Dissertations
The current study examined verbal and visuospatial memory abilities as potential mediators of the relationship among ADHD behavior problems and near- and long-term scholastic achievement. Scholastic achievement was measured initially and at 4-year follow-up in an ethnically diverse sample of children (N = 325). Nested composite (reading, math, language) and domain-specific reading structural equation models revealed that ADHD behavior problems exerted a negative influence on scholastic achievement measures, both initially and at follow-up. Much of this influence, however, was mediated by verbal memory’s contribution to near-term achievement, whereas visuospatial memory contributed more robustly to long-term achievement. For the domain-specific math …
Tactile Working Memory And Multimodal Loading, Peter Terrence
Tactile Working Memory And Multimodal Loading, Peter Terrence
Electronic Theses and Dissertations
This work explored the role of spatial grouping, set size, and stimulus probe modality using a recall task for visual, auditory, and tactile information. The effects of different working memory (WM) loading task modalities were also examined. The Gestalt spatial organizing principle of grouping showed improvements in response times for visual and tactile stimulus probes with large set sizes and apparently allowed participants to effectively chunk the information. This research suggests that tactile information may use spatial characteristics typically associated with visual information, as well as sequential characteristics normally associated with verbal information. Based on these results, a reformulation of …
Empirical Modeling Of A Marijuana Expectancy Memory Network In Children As A Function Of Age And Marijuana Use, Jacqueline Alfonso
Empirical Modeling Of A Marijuana Expectancy Memory Network In Children As A Function Of Age And Marijuana Use, Jacqueline Alfonso
Electronic Theses and Dissertations
The present investigation modeled the expectancy memory organization and likely memory activation patterns of marijuana expectancies of children across age and marijuana use. The first phase of the study surveyed 142 children to obtain their first associate to marijuana use. From their responses, the Marijuana Expectancy Inventory for Children and Adolescents (MEICA) was developed. The second phase of the study administered the MEICA to a second sample of 392 children to model marijuana expectancy organization and probable memory activation paths of marijuana users versus never-users. Results indicated that irrespective of age, adolescents who have used marijuana tend to emphasize positive-negative …
