NEURAL DEDIFFERENTIATION IN RELATION TO RISK FOR ALZHEIMER’S DISEASE Nathan C. Hantke, B.A. Marquette University, 2010 Functional magnetic resonance imaging (fMRI) research indicates that as an individual’s age increases, the task-related spatial extent of neural activation increases. This decrease in neural specificity, or dedifferentiation, is often demonstrated by older adults during challen...

Older adults were less likely than young adults to spontaneously recollect the source of familiarity for previously read nonfamous names. Older adults were more likely to call old nonfamous names famous when subsequently encountered in a fame judgment task. Poor source monitoring by the elderly could not be accounted for by inability to recognize earlier read nonfamous names when specifically a...

Two fundamental factors affecting the speed of spoken word production are lexical frequency and sentential constraint, but little is known about their timing and electrophysiological basis. In the present study, we investigated event-related potentials (ERPs) and oscillatory brain responses induced by these factors, using a task in which participants named pictures after reading sentences. Sent...

Data are presented on two computerized tests of everyday verbal learning: Paired associate learning of First-Last Names (FLN), and the Grocery List Selective Reminding Test (GLSRT). MANOVA and multiple regression analyses demonstrated that performance on FLN and GLSRT was most strongly related to age, with significant secondary associations found for gender, with females performing better than ...

These patterns are part of an ongoing project to capture and document techniques for the design and construction of systems that must function under tight memory constraints. Some patterns from this project are already published in the book Small Memory Software in the Addison-Wesley Software Patterns Series. The full chapter will include three additional patterns, together with more structure ...

The problem of matching strings allowing errors has recently gained importance, considering the increasing volume of online textual data. In geotechnologies, approximate string matching algorithms find many applications, such as gazetteers, address matching, and geographic information retrieval. This paper presents a novel method for approximate string matching, developed for the recognition of...

We consider wait-free solutions to the renaming problem for shared-memory multiprocessing systems 3, 5]. In the renaming problem, processes are required to choose new names in order to reduce the size of their name space. Previous solutions to the renaming problem have time complexity that is dependent on the size of the original name space, and allow processes to acquire names only once. In th...
