We are capable of effortlessly parsing a complex scene presented to us. In order to do
this, we must segregate objects from each other and from the background. While this
process has been extensively studied in vision science, it remains relatively less
understood in auditory science. This thesis sought to characterize the neuroelectric
correlates of auditory scene analysis using electroencephalography. Chapter 2 determined
components evoked by first-order energy boundaries and second-order pitch boundaries.
Chapter 3 determined components evoked by first-order and second-order discontinuous
motion boundaries. Both of these chapters focused on analysis of event-related potential
(ERP) waveforms and time-frequency analysis. In addition, these chapters investigated
the contralateral nature of a negative ERP component. These results extend the current
knowledge of auditory scene analysis by providing a starting point for discussing and
characterizing first-order and second-order boundaries in an auditory scene. / x, 90 leaves : col. ill. ; 29 cm
