Shared Genetic And Environmental Influences On Fear, Anxiety, Posttraumatic Stress, And Brain Morphometry, Chelsea Sawyers
Theses and Dissertations
Anxiety disorders (ADs) and stress-related disorders are some of the most common psychiatric disorders in the United States. Like other c0mplex psychiatric illness, genetics and neuroimaging research has focused on understanding their underlying neurobiology. Areas within the fear-network play important roles in threat perception, fear conditioning/learning, cognitive processing, and modulation of fear responses including contextual modulation and extinction and have been implicated in ADs as well as stress disorders such as posttraumatic stress disorder (PTSD). The primary gap in the current search for underlying biological mechanisms is in whether biomarkers associated with disorders share genetic influences with the disorders they …
Phonological And Orthographic Repetition Effects Across Words In Adult Skilled Sentence Reading: An Eye Movement Analysis, Ti Yan
Theses and Dissertations
Visual word recognition is central to skilled silent reading. This project investigated the situation in which two words within a sentence share phonological information. Previous eye movement reading studies have made attempts to understand how prior exposure to a word could influence the speed of recognizing another phonologically and/or orthographically similar word. Results have been accounted for by different visual word recognition models which agree on the competition among similar words in the lexicon. However, a closer inspection revealed several concerns. First, there is little direct evidence demonstrating the across-word effect in normal reading. Second, the existing work in English …
