When a sequence of two tones is presented over headphones in an ascending or descending order of pitch, it is heard as correspondingly ascending or descending in space. The illusion of spatial change that accompanies pitch change can be induced onto a pair of noise bursts by presenting them in synchrony with the tones. When cues known to produce stream segregation are introduced, the perceived ...

The analysis of the auditory scene begins from the moment we hear sounds, making it possible for the infant to distinguish the mother's voice from other sounds in the environment. The purpose of the study was to determine, in two experiments, whether the frequency separation threshold, at which the perception of a mixture of sounds turns from being perceived as one stream to two streams, differ...

Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic theory of granular flow has been used. The mass fraction profiles of the different-sized partic...

This article presents a probabilistic model of polyphonic music analysis. Taking a note pattern as input, the model combines three aspects of symbolic music analysis— metrical analysis, harmonic analysis, and stream segregation—into a single process, allowing it to capture the complex interactions between these structures. The model also yields an estimate of the probability of the note pattern...

Our understanding of cortical electrophysiology and anatomy at the single-cell level has led to the present day insight in to the function of connections linking cortical areas. This made it possible to elaborate the cortical hierarchy in the early 1990s and was a prerequisite for the development of present day generative models of perception. These computational hierarchical models make strong...

There is uncertainty concerning the extent to which the auditory streaming effect is a function of attentive or preattentive mechanisms. The mismatch negativity (MMN), which indexes preattentive acoustic processing, was used to probe whether the segregation associated with the streaming effect occurs preattentively. In Experiment 1, alternating high and low those were presented at fast and slow...

Title of Document: Auditory streaming: behavior, physiology, and modeling Ling Ma, Doctor of Philosophy, 2011 Directed By: Professor Shihab A. Shamma, Department of Electrical and computer Engineering, Institute of Systems Research Auditory streaming is a fundamental aspect of auditory perception. It refers to the ability to parse mixed acoustic events into meaningful streams where each stream ...

Cortico-cortical projections for visual processing that originate from the striate cortex are organized into two streams. The dorsal stream projects to the parietal region and the ventral stream to the inferior temporal region. One hypothesis is that the dorsal stream processes visual spatial information, and the ventral stream processes visual object information. Although recognition of human ...

A comprehensive mathematical model based on the discrete particle model and computational fluid dynamics was utilized to investigate mixing and segregation of particles in fluidized beds at high pressure. To quantify the extent of mixing in the bed, the Lacey mixing index was used. Simulations were carried out with different mass fractions of small particles at various pressures ranging from 1 ...
