An Online Vignette Study To Examine The Outcomes Of A Preclinical Alzheimer Disease Diagnosis, Matthew John Wynn
An Online Vignette Study To Examine The Outcomes Of A Preclinical Alzheimer Disease Diagnosis, Matthew John Wynn
Arts & Sciences Electronic Theses and Dissertations
As Alzheimer disease research forges ahead, and new potential treatments are developed, a conceptualization is emerging of a presymptomatic disease stage. This stage, known as preclinical Alzheimer disease, is characterized by the buildup of amyloid beta and tau proteins in the brain to abnormal levels in a cognitively normal person. There are unknown potential risks and benefits of communicating biological marker risk information for Alzheimer disease using the preclinical Alzheimer disease diagnostic label. The current study uses a vignette methodology to measure older adults’ understanding of risk information when presented with information regarding their risk for developing Alzheimer dementia. Participants …
Testing The Common-Mechanisms Theory Of False Hearing And False Memory: The Roles Of Executive Functioning And Inhibitory Control, Eric Failes
Arts & Sciences Electronic Theses and Dissertations
Recent studies have shown that older adults are more susceptible to context-based misperceptions in hearing than are younger adults, a phenomenon that has been referred to as false hearing (Rogers et al., 2012; Sommers et al., 2015). The authors of these studies have noted similarities between false hearing and false memories (Jacoby et al., 2005), suggesting that the two phenomena may arise from similar cognitive mechanisms. The present dissertation project investigated similarities between false hearing and false memories. In Experiment 1, I directly compared susceptibility to false hearing and false memories in younger and older adults. I then investigated two …
