Description
“The Moral Sense of Touch: Teaching Tactile Values in Late Medieval England” investigates the intersections of popular science and religious education in the late fourteenth and fifteenth centuries. Taking an interdisciplinary approach, the project draws together a range of textual artifacts, from scientific manuals to private prayerbooks, to reconstruct the vast network of touch supporting the late medieval moral syllabus. I argue that new scientific understandings of the five senses, and specifically the sense of touch, had a great impact on the processes, procedures, and parlances of vernacular religious instruction in late medieval England. The study is organized around a set of object lessons that realize the materiality of devotional reading practices. Over the course of investigation, I explore how the tactile values reinforcing medieval conceptions of pleasure and pain were cultivated to educate and, in effect, socialize popular reading audiences. Writing techniques and technologies—literary forms, manuscript designs, illustration programs—shaped the reception and user-experience of devotional texts. Focusing on the cultural life of the sense of touch, “The Moral Sense of Touch” provides a new context for a sense based study of historical literatures, one that recovers the centrality of touch in cognitive, aesthetic, and moral discourses.

Description
Our ability to estimate the position of our body parts in space, a fundamentally proprioceptive process, is crucial for interacting with the environment and movement control. For proprioception to support these actions, the Central Nervous System has to rely on a stored internal representation of the body parts in space. However, relatively little is known about this internal representation of arm position. To this end, I developed a method to map proprioceptive estimates of hand location across a 2-d workspace. In this task, I moved each subject's hand to a target location while the subject's eyes were closed. After returning the hand, subjects opened their eyes to verbally report the location of where their fingertip had been. Then, I reconstructed and analyzed the spatial structure of the pattern of estimation errors. In the first couple of experiments I probed the structure and stability of the pattern of errors by manipulating the hand used and tactile feedback provided when the hand was at each target location. I found that the resulting pattern of errors was systematically stable across conditions for each subject, subject-specific, and not uniform across the workspace. These findings suggest that the observed structure of pattern of errors has been constructed through experience, which has resulted in a systematically stable internal representation of arm location. Moreover, this representation is continuously being calibrated across the workspace. In the next two experiments, I aimed to probe the calibration of this structure. To this end, I used two different perturbation paradigms: 1) a virtual reality visuomotor adaptation to induce a local perturbation, 2) and a standard prism adaptation paradigm to induce a global perturbation. I found that the magnitude of the errors significantly increased to a similar extent after each perturbation. This small effect indicates that proprioception is recalibrated to a similar extent regardless of how the perturbation is introduced, suggesting that sensory and motor changes may be two independent processes arising from the perturbation. Moreover, I propose that the internal representation of arm location might be constructed with a global solution and not capable of local changes.
