Homosexuality and the United Methodist Church: An Ecclesiological Dilemma

Since 1968 The United Methodist Church has publicly debated the status and roles of homosexual persons in the life of the Church, creating considerable conflict within the Denomination. Academic research on the question of homosexuality and the Church has often focused on theological understandings of homosexuality and on the ways the conflict reflects broader "culture wars" in society. Yet little attention has been given to how the Church's concrete practices and polity toward homosexual persons reflect underlying tensions within the ecclesiological identity of the Denomination. This dissertation proposes that the issue of homosexuality is a critically important case study for exploring the practical ecclesiology of The United Methodist Church. In an effort to identify tensions within contemporary United Methodism's practical ecclesiology, it traces in detail the history of the denominational debate over homosexuality since 1968 and articulates the diverse and often conflicting ecclesiological commitments embedded within that debate. Focusing on the debate itself as a practice of the Church, this dissertation illustrates the ways in which the controversy over sexuality reflects the Denomination's conflicted practical ecclesiology. By examining the rhetoric of the sexuality debates in The United Methodist Church from 1968 to 2008, and by articulating the ecclesiological commitments embedded in those debates, the dissertation reveals a fundamental conflict over interpretations of ecclesial unity. Moreover, the dissertation explores the extent to which the conflict over unity reflects ecclesiological tensions present in John Wesley's own practical ecclesiology; and it asks whether or not contemporary interpretations of United Methodist ecclesiology might provide a normative framework for assessing and resolving the underlying ecclesial conflict at work in sexuality debates. The dissertation concludes by exploring the practice of public narrative as a concrete strategy that might be employed by the Denomination to reconcile the diverging ecclesiological visions within the contemporary church so that a clear and consensual ecclesiology might emerge.

Task-Irrelevant Perceptual Learning Specific to the Contrast Polarity of Motion Stimuli

Studies of perceptual learning have focused on aspects of learning that are related to early stages of sensory processing. However, conclusions that perceptual learning results in low-level sensory plasticity are of great controversy, largely because such learning can often be attributed to plasticity in later stages of sensory processing or in the decision processes. To address this controversy, we developed a novel random dot motion (RDM) stimulus to target motion cells selective to contrast polarity, by ensuring the motion direction information arises only from signal dot onsets and not their offsets, and used these stimuli in conjunction with the paradigm of task-irrelevant perceptual learning (TIPL). In TIPL, learning is achieved in response to a stimulus by subliminally pairing that stimulus with the targets of an unrelated training task. In this manner, we are able to probe learning for an aspect of motion processing thought to be a function of directional V1 simple cells with a learning procedure that dissociates the learned stimulus from the decision processes relevant to the training task. Our results show learning for the exposed contrast polarity and that this learning does not transfer to the unexposed contrast polarity. These results suggest that TIPL for motion stimuli may occur at the stage of directional V1 simple cells.
