Age Differences In Reward Anticipation And Memory, Kristen L. Cushman

Masters Theses & Specialist Projects

Aging research on item- and associative-recognition memory has demonstrated that older adults are deficient in forming associations between two unrelated stimuli. Although older adult performance on tests of item-recognition is similar to younger adult performance, older adults perform worse than younger adults on tests of associative memory (Naveh-Benjamin, Hussain, Guez, & Bar-On, 2003). In addition to the idea that younger adult performance on associative-recognition tests is superior to that of older adults, research has shown that reward cues can enhance motivated learning and item memory performance of younger adults. In an fMRI study that examined the influence of reward anticipation …

Teleconnective Influences On The Strength Of Post-Tropical Cyclones, Jeremy Young

Masters Theses & Specialist Projects

Over the 1951-2009 time period, 47% of all tropical systems in the Atlantic Basin transitioned to post-tropical storms. These storms are capable of producing hurricaneforce winds, torrential, flooding rains and storm surge that floods coastal areas. This study adds to previous climatological work by completing a case-study of Hurricane Ike (2008) and examining how teleconnections such as the El Niño Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO), the Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) contribute to the strength of a transitioning post-tropical storm.

Teleological Reasoning In Adults: Believing In The Purpose Of Events, Carrie Jeanette Guggenmos

Masters Theses & Specialist Projects

Teleological reasoning reflects the general tendency to view objects, behaviors and events in terms of their “purpose.” Although healthy educated adults tend to refrain from committing errors in teleological reasoning about objects, our knowledge regarding how adults reason about events is limited. It has been suggested that teleological reasoning biases our interpretations of emotionally significant and unexpected life events of which a physical or social cause is absent or unsatisfactory. The current investigation seeks to better understand the types of events that evoke a teleological perspective and the conditions and individual difference factors that facilitate it. The results revealed that …

Reading Ineffability And Realizing Tragedy In Stuart Moulthrop's Victory Garden, Michael E. Gray

Masters Theses & Specialist Projects

Victory Garden, Stuart Moulthrop’s 1991 classic hyperfiction, presents a nonlinear story of U. S. home front involvement in the First Gulf War in a way that facilitates confusion and mimics a "fog of war" sort of (un)awareness. Using Storyspace to build his complex narrative, Moulthrop incorporates poetry, fiction, historical references, and low-tech graphic novel type elements. Among the graphic components are all-black and all-white screens that function as variables. Overtly, these screens speak of closure and signify unconsciousness; however, their nonverbal role may also be linked to the ineffability trope as used by Dante Alighieri and re-interpreted by contemporary …
