Process Dissociation Analyses Of Memory Changes In Healthy Aging, Preclinical, And Very Mild Alzheimer Disease: Evidence For Isolated Recollection Deficits, Peter R. Millar
Arts & Sciences Electronic Theses and Dissertations
Recollection and familiarity are independent processes that contribute to memory performance. Recollection is dependent on attentional control, which breaks down in early-stage Alzheimer disease (AD), whereas familiarity is independent of attention. The present study examines the sensitivity of recollection estimates based on Jacoby’s (1991) process dissociation procedure to AD-related biomarkers in a large sample of well-characterized cognitively normal older adults (N = 519) and the extent to which recollection discriminates these individuals from individuals with very mild symptomatic AD (N = 64). Participants studied word pairs, e.g., “knee bone,” then completed a primed, explicit, cued fragment-completion memory task, e.g., “knee …
Exploring Animacy As A Mnemonic Dimension, Joshua Edward Vanarsdall
Exploring Animacy As A Mnemonic Dimension, Joshua Edward Vanarsdall
Open Access Dissertations
There is a great deal of evidence across cognitive science that animacy, or more generally, the features that make up what it means to be a living thing, is a foundational dimension of human cognition. In perception, animates both capture attention (Pratt, Radulescu, Guo, & Abrams, 2010) and are relatively immune to change blindness (New, Cosmides, & Tooby, 2007). Developmental work places the animate-inanimate distinction as one of the first categories children learn (Opfer & Gelman, 2011). Work in neuroscience points toward a fundamental role for animacy in semantic memory (Caramazza & Mahon, 2003), and linguists have identified animacy as …

Children’S Ability To Identify An Unusual Occurrence Of A Repeated Event, Mckenzie K. Vanderloon
Theses and Dissertations (Comprehensive)
Abstract
Research on script memory shows that individuals have a difficult time isolating single instances of a repeated event because a generic script (e.g., one has a generic script for typical grocery shopping; grab a cart, gather items, then pay) has formed over time. Scripts capture the “gist” of what usually happens and allow individuals to predict what probably occurred based on the robustness of the script. Thus, individuals are able to identify details of what occurs; however, piecing which details came from a particular incident poses its challenges, especially for children. Source monitoring is the ability to accurately differentiate …
