Separating Component Signals Of Episodic Simulation Using A Catch Trial Design, Adrian W. Gilmore Dec 2012

Separating Component Signals Of Episodic Simulation Using A Catch Trial Design, Adrian W. Gilmore

All Theses and Dissertations (ETDs)

Tasks that require mentally simulating events, such as remembering events from one’s past and imagining events from one’s future, have been shown to involve a highly overlapping set of brain regions. Across a growing number of studies, relatively few regions have been found that show differences in activity between remembered and imagined events. However, studies have not disambiguated neural activity related to task orientation: i.e., preparing to remember events from the past or imagine events in the future) from activity related simulating events, per se. The current experiment uses functional MRI and employs a catch trial design to test the …


Sensory And Cognitive Declines In Older Adults: A Longitudinal Study, Melanie Storm Bauer Aug 2012

Sensory And Cognitive Declines In Older Adults: A Longitudinal Study, Melanie Storm Bauer

All Theses and Dissertations (ETDs)

In a recent cross-sectional study, as has been found in numerous previous studies, Sommers et al.: 2011) found that age-related declines in hearing, as assessed by pure-tone thresholds, begin around age 20 and continue across the lifespan. In another article published from the same cross-sectional dataset, Hale et al.: 2011) found that working memory ability also begins declining around age 20 and continues throughout life. The present study is a longitudinal follow-up of these two studies in which a sub-sample of older adults: ≥65 years old at the time of original testing approximately four years ago) were re-tested on sensory …
