Show A SUPERNATURAL CAWVCITY FOR SECRECY IMAGINED EGOCENTRIC ROTATIONS: AN FMRI STUDY Leigh M. Moss (Kim Lau), Department of English, University of Utah, Salt Lake City, Utah 84112 This paper seeks to explore the world of secrecy in The Gospel of Mark. Theories of secrecy, regarding its structure and ef-fects, will be used to extrapolate mean-ing from Mark's text. Questions that will be proposed and discussed from the text will include, but not be limited to, the following: Why Jesus orders those he performs miracles on to be silent? Why Jesus insists upon secrecy and si-lence at the same time that he performs public miracles and teachings? What effects come of Christ's secrecy? And, how Christ manages to consistently sur-prise his disciples despite their knowing him? With the help of William Wrede's book The Messianic Secret, I will argue that despite Christ's public healings, his dramatically different, miracle-working body, his supernatural teachings, and enormous following, he remains hid-den. The Gospel of Mark is an interest-ing case of secrecy for this reason. Even after Jesus is set apart as secret, he de-fies the scrutiny that would reveal him. Jayson Neil, (Sarah Creem-Regehr) Deaprtment of Psychology, University of Utah Spatial transformations are a necessary part of interacting with the world on a daily basis. For example, humans must be able to recognize an object at a new orientation or keep track of the location of an object even when it is no longer in view. We used functional magnetic resonance imaging IfMRI) to explore one type of spatial trans-formation, imagined egocentric rotations. Subjects were presented with an image of a rotated hand while in the scanner. They performed two tasks, both of which required a right versus left decision. In the first task subjects imagined rotating their hand to de-cide if the hand was a left or right hand and in the second task subjects imagined rotat-ing their perspective around the hand, mak-ing a decision about whether a part of the hand was on their left or right. Behavioral data in the form of response time and accu-racy were recorded in order to verify task ex-ecution. Two types of fMRI paradigms were employed; a block paradigm and an event-related paradigm. The results showed that imagined egocentric hand and perspec-tive rotations share many regions common to imagined rotation tasks in general. This network consisted of frontal, parietal, and occipital activation in the cortex, along with significant activity in the cerebellum, cau- date, and hippocampus. However, there were differences in activation between the two tasks. The hand task elicited more acti-vation in "motor processing regions includ-ing the left inferior and superior frontal gyri, supplementary motor area, and regions of the temporal lobe and cerebellum. The per-spective task elicited more activation in the middle occipital gyrus and the medial frontal gyrus. These findings suggest that although some shared mechanisms across different types of egocentric spatial transformations exist, there are notable differences as well. Namely, imagined hand rotations recruit regions of the motor system involved in real movements to a greater extent than imagined perspective rotations. |
