Hearing Where Things AreOxtoby, Donald L. 10 1900 (has links)
<p>One of the central questions in the philosophy of sounds and hearing is the question of space: what spaces or locations, if any, do sound perceptions make one aware of? When I hear a sound, do I perceive the direction of the sound? The direction (or distance) of the sound's source? The boundaries or dimensions of the space the sound is produced in, or of the source itself? And if sound perceptions do make one aware of space, then with what level of determinacy?</p> <p>In the first chapter of this essay, I describe my approach to sounds and hearing, and state what I take to be the fundamental challenges for any view of sound perception. For one, I take the everyday experience of sounds to be one of the most significant obstacles to an account of sound perception, and one that has scarcely been recognized as such. In everyday hearing, we are not the least bit concerned with sounds. We use sounds to gather information about the behaviour of their sources, which are typically the object of our attention whenever we perceive a sound. If I hear the sound of a car honking or a person speaking, I immediately pay attention to the car and how I can avoid it, or to the person and the meaning they intend to communicate. In everyday hearing, our awareness of sounds is similar to our awareness of windowpanes while watching the goings on outside. Consequently, the everyday experience of sounds is problematic as a model of sound perception.</p> <p>In the second and third chapters, I discuss the two most popular views of sound perception in the philosophical literature, the remote view and the non-spatial view. Since these views have received much attention in the literature, I spend more time raising objections to them in chapter III than describing them in chapter II. One of the principle aims of this essay is to make the case that both of these views are mistaken, despite the valuable insights contained in each.</p> <p>In the fourth and fifth chapters, I discuss the medial view. While the idea that sounds are sound waves located in a medium is the predominant view of sounds themselves in auditory science and the history of philosophy, the view that we hear sounds to be located in the medium has received little attention. Some objections to the medial view have been raised, which I address in chapter V, but very little has been said to defend or even describe the medial view. Part of the motivation for this essay is that I am struck by the fact that the medial view, which would seem to follow naturally from auditory science and the history of philosophy, has been so little discussed. Consequently, the bulk of this essay is dedicated to a description and defence of the medial view.</p> / Master of Arts (MA)

Assessing the Presence of a Nonspatial Joint Compatibility Effect: Generalizability of the Joint Simon Task as a Measure of Self-Other Integration in Joint ActionSobel, Briana M 01 January 2024 (has links) (PDF)
The joint Simon task is a cognitive reaction time task used to assess shared representations and self-other integration when performing a collaborative task with a partner. However, it is unclear if the underlying mechanisms are specific to representing spatial information or are more general. The objective of the current study was to assess a nonspatial joint Simon compatibility effect. Participants completed the joint Simon task with a partner while seated side-by-side, face-to-face, back-to-back, or with their partner not in the room. They completed the task three times, once with horizontal stimuli (left/right of center), once with vertical stimuli (above/below center), and once with central stimuli (at center). In the central task, compatibility was in color where participant responses (assigned red or green response buttons and gloves) were compatible or incompatible to the stimuli (colored red or green). Results showed no significant compatibility effect for any task in any response orientation condition, indicating no evidence of a nonspatial compatibility effect. Results even failed to replicate the standard joint Simon effect of a spatial compatibility effect in the horizontal task when seated side-by-side. However, exploratory analyses showed a significant nonspatial color compatibility effect in the central task for those assigned green in the side-by-side condition only, indicating that the presence of color in the participants' response (i.e., colored responses button and gloves) may have interfered with representing spatial information. This finding has implications for both theory and application of the joint Simon task, indicating it is sensitive to small changes, occurs for features besides location, and may be most effective when seated side-by-side. Additionally, the broader implications for the cognitive and practical study of joint action show the importance of how different features influence shared representations, how different colors are perceived and represented, and how different response orientations influence performance.
