This study aims to investigate effects of time pressure and stimulus format on false recognition. The spreading activation theory offers an explanation for false memories. This study explores the range of the spreading activation theory, questioning if visual representations are included in a stimuli's activation. The study also tests the effects of time pressure on false recognition. Participants studied study categorical word lists. At test participants were be placed in a speeded or

It was expected that, while both should elicit false recognition, false word recognition rates would be higher than false image recognition rates. It was also expected that there to be greater false recognition in the timed condition because the effects of spreading activation would be stronger when less time is allotted and the critical item should be falsely recognized. The study found that images could elicit false recognition suggesting the effects of spreading activation are more conceptually driven rather than simply lexically driven. FAMILIAL PARAGANGLIOMAS AND PHEOCHROMOCYTOMAS: SUCCINATE DEHYDROGENASE DEFICIENCY AS A RESULT OF SDHB MUTATION Matthew Strickland ('10) and Jared Tepper ('10), Chemistry Succinate Dehydrogenase (complex II; or succinate:ubiquinone oxidoreductase, SDH) is a functional member of both the citric acid cycle (TCA) and the aerobic respiratory chain. Complex II couples the oxidation of succinate to fumarate in the mitochondrial matrix with the reduction of ubiquinone in the membrane. SDH is composed of two hydrophilic subunits, including an iron-sulfur protein (SDHB), both of which are anchored to the membrane by an additional pair of hydrophobic subunits. Recently, reports have shown that germline mutations in the genes coding for the catalytic subunits of SDH are associated with familial pheochromocytomas and paragangliomas. Paragangliomas are a type of neuroendocrine tumour, and are closely related to pheochromocytomas which generally manifest in the medulla of the adrenal glands. The purpose of this review was to investigate whether an association between SDHB subunit mutations and these conditions exists. Further, SDH deficiency as a result of this mutation was examined with respect to metabolism. These findings suggest that there is a strong association between SDHB mutation and the development of paragangliomas and pheochromocytomas thus extending the link between mitochondrial dysfunction and tumourigenesis. 'CONTENTMENT IN MY HEART': EVANGELICAL WOMEN AND SPIRITUAL JOURNEYS Elizabeth Doran ('09), Sociology This honors project is an in-depth, qualitative study of a central Maine evangelical church. My focus is on five women and their religious journeys and experiences as Christian women. I explore a number of issues: the appeal of this church community to contemporary women; the connections and the contrasts between what the church leaders espouse and what ordinary female members believe; the ways in which the women develop their own personal relationships with Christ, the evangelical tradition, and other members of the community; and my own journey as a student of sociology and a qualitative researcher.
