Cellular Specializations For Sound Localization, Kevin C. Rowland May 2003

Cellular Specializations For Sound Localization, Kevin C. Rowland

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the key elements in auditory perception is the localization of sounds in space. The major cues used for localizing sounds in the azimuthal plane have long been recognized as interaural differences in time of arrival of a sound and amplitude differences between the two ears (Rayleigh 1907; Thompson 1878). High frequency sounds are reflected by the head and thereby produce interaural level differences (ILDs) that are used for localization. The head does not reflect low frequency sounds and so interaural timing differences (ITDs) are used. One of the cell groups of the auditory brainstem, the medial superior olive …

Experimental Support For The Use Of Story Telling To Guide Behavior: The Effects Of Story Telling On Multiple And Mixed Fixed Ratio (Fr) /Differential Reinforcement Of Low Rate (Drl) Schedule Responding., Michelle Heffner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Story telling is universal, and the significance of stories may lie in their ability to guide behavior. An informal analysis of story telling suggests that stories provide a model of behavior, establish motivation, and stimulate the development of self-generated rules. In psychotherapy, stories illustrate points, suggest solutions, improve client insight, increase motivation, and establish rapport (Barker, 1996; Zeig, 1980). Despite the popular use of stories across theoretical orientations and treatment approaches, it is not clear if stories facilitate behavior change. Observational and correlational data suggest that stories may guide behavior, but there is no experimental support for these findings. The …
