In the current study, I proposed that previous occurrence of sexual or physical trauma would predict both decreased frequency of touch in a current intimate relationship and poorer individual well-being, and that these relations would be explained by negative touch attitudes. Results supported these hypotheses, suggesting that lingering negative touch attitudes following trauma could be an underlying mechanism affecting social and individual functioning. As seen in our model, these attitudes fully mediated the effects between previous sexual or physical trauma and individual well-being, as well as frequency of touch. This understanding can help provide further insight into the repercussions of trauma and the underlying mechanisms attributing to continued negative effects.
The goal of this study was to look at touch and dance from different views to gain a better perspective on the benefits of touch, mainly when used in dance and also perhaps in broader contexts. Part of this investigation also looked at the stigmatized view of touch in the American culture and in turn the lack of knowledge about, and comfort with touch in our society. A personal research component involved the creation of a solo reflecting about the question of why I connect with touch so intensely. The bulk of the study involved facilitating touch experiences in two introductory level dance classes for high school students. Daily journal entries were collected from each of the eighty students that focused on their personal experiences with touch in a series of six movement sessions. The study shows that bringing touch to the dance classroom has multiple benefits, including promoting a greater understanding and acceptance of the sense of touch, a positive impact on students' views about dance, and a break down of preconceived notions about the mind and the body.
Methods such as vibratory sensory substitution have shown promise for providing prosthesis users with a sense of contact and have proved helpful in completing motor tasks. In this thesis, two experiments were conducted to determine whether vibratory cues could be useful in discriminating between sizes. In the first experiment, subjects were asked to grasp a series of hidden virtual blocks of varying sizes with vibrations on the fingertips as indication of contact and compare the size of consecutive boxes. Vibratory haptic feedback significantly increased the accuracy of size discrimination over objects with only visual indication of contact, though accuracy was not as great as for typical grasping tasks with physical blocks. In the second, subjects were asked to adjust their virtual finger position around a series of virtual boxes with vibratory feedback on the fingertips using either finger movement or EMG. It was found that EMG control allowed for significantly less accuracy in size discrimination, implying that, while proprioceptive feedback alone is not enough to determine size, direct kinesthetic information about finger position is still needed.
