The Effect Of The Similarity Of Events On Change Deafness, Caroline Cole May 2018

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°, …


The Effects Of Speaking Rate Manipulations On The Perception Of Voicing Contrasts, Sarah M. Howell May 2018

The Effects Of Speaking Rate Manipulations On The Perception Of Voicing Contrasts, Sarah M. Howell

Senior Honors Projects, 2010-2019

Phoneme-level research involving speaking rate has typically relied on a single method of synthetically manipulating rate of speech by compressing the vowel portion of a syllable. This does not mimic what occurs during natural speech production, and therefore could be influencing the perception of voicing contrasts. An experiment was conducted to address this problem by constructing a continuum of voice onset times for the velar place of articulation and then subsequently altering the rate of speech using three methods of manipulation: compressing the vowel, compressing the consonant and vowel proportionate to what occurs naturally, and compressing the total duration of …
