The Effects Of Timbre On Perceptual Grouping In A Melodic Sequence, Thomas Rohaly
The Effects Of Timbre On Perceptual Grouping In A Melodic Sequence, Thomas Rohaly
Masters Theses, 2010-2019
The current investigation sought to examine the effects of timbre on perceptual grouping in melodic sequences. While past research has shown that timbre shifts influence listeners’ pitch perception on a note-to-note basis (e.g., see Pitt, 2004; Russo & Thompson, 2005, & Creel, Newport, & Aslin, 2004), the current investigation extended this to timbre’s influence on pitch perception in the context of a melodic phrase. In Experiment 1, participants were presented with melodic sequences, made of sawtooth-like waves. Sequences, consisting of 6 tones, were followed by a target tone that had a static, dull, or bright timbre shift through the use …
The Effect Of The Similarity Of Events On Change Deafness, Caroline Cole
The Effect Of The Similarity Of Events On Change Deafness, Caroline Cole
Senior Honors Projects, 2010-2019
Change deafness is a perceptual phenomenon that occurs when an observer fails to rapidly detect an above-threshold change in a sound source. The present research represented an initial investigation into one stimulus factor, the perceived similarity between array events, that potentially gives rise to change deafness to continuously moving target events. Participants (N=13) were presented with arrays of three simultaneous tones of inharmonic, synthetic /a/ and /i/ vowels. Each array event had a distinct pitch [low (A2), middle (D#3), high (B4)] and starting location in perceived space on the azimuth (-40°, …
Context Effects Of False Remember Responses In Older And Younger Adults, Casey M. Williamson
Context Effects Of False Remember Responses In Older And Younger Adults, Casey M. Williamson
Masters Theses, 2010-2019
Although different theories attempt to explain the underlying mechanism of false remembers, none have been able to adequately describe this process. The current study aims to determine if a specific contextual detail (i.e., font color) can be tied to false remembers (i.e., false memory that contains contextual or perceptual details), and if there are age differences in this ability. Using the Deese, Roediger, McDermott (DRM) paradigm (Deese, 1959; Roediger & McDermott, 1995) and the contextual detail of font color, this study investigated if older and younger adults can tie a specific color to studied items and critical lures (non-presented semantic …
