“…Research in psychoacoustics has already led to the identification of such tasks. For instance, several studies have shown that listeners are poorer at identifying the temporal order of sounds, or detecting changes in their relative timing, if these sounds fall into separate streams than if they fall into the same stream (van Noorden 1975;Roberts et al 2002Roberts et al , 2008Micheyl and Oxenham 2010). In such tasks, therefore, stream segregation impedes performance.…”

“…In general, faster presentation rates, or shorter tone intervals, and longer sequence lengths promote segregation (van Noorden 1975;Bregman 1978;Bregman et al 2000). Auditory streaming has been demonstrated using a variety of sounds, including pure tones, harmonic complex tones (Cusack and Roberts 1999;Grimault et al 2000Grimault et al , 2001Roberts et al 2002Roberts et al , 2008, synthetic vowels (Gaudrain et al 2007(Gaudrain et al , 2008, and noises (Bregman et al 2001;Grimault et al 2002), with streaming depending on differences in fundamental frequency (F0), spectral content, or temporal envelope modulation rate.…”

The perceptual organization of sound sequences into auditory streams involves the integration of sounds into one stream and the segregation of sounds into separate streams. "Objective" psychophysical measures of auditory streaming can be obtained using behavioral tasks where performance is facilitated by segregation and hampered by integration, or vice versa. Traditionally, these two types of tasks have been tested in separate studies involving different listeners, procedures, and stimuli. Here, we tested subjects in two complementary temporal-gap discrimination tasks involving similar stimuli and procedures. One task was designed so that performance in it would be facilitated by perceptual integration; the other, so that performance would be facilitated by perceptual segregation. Thresholds were measured in both tasks under a wide range of conditions produced by varying three stimulus parameters known to influence stream formation: frequency separation, tone-presentation rate, and sequence length. In addition to these performancebased measures, subjective judgments of perceived segregation were collected in the same listeners under corresponding stimulus conditions. The patterns of results obtained in the two temporaldiscrimination tasks, and the relationships between thresholds and perceived-segregation judgments, were mostly consistent with the hypothesis that stream segregation helped performance in one task and impaired performance in the other task. The tasks and stimuli described here may prove useful in future behavioral or neurophysiological experiments, which seek to manipulate and measure neural correlates of auditory streaming while minimizing differences between the physical stimuli.

“…Previous studies [36,55,[64][65][66] have consistently reported perceptual reset (i.e. a restart from the state at the outset dominated by the integrated percept, with the necessity to gather evidence for the segregated organization anew) when parameter changes were introduced in the auditory streaming paradigm.…”

Auditory stream segregation involves linking temporally separate acoustic events into one or more coherent sequences. For any non-trivial sequence of sounds, many alternative descriptions can be formed, only one or very few of which emerge in awareness at any time. Evidence from studies showing bi-/multistability in auditory streaming suggest that some, perhaps many of the alternative descriptions are represented in the brain in parallel and that they continuously vie for conscious perception. Here, based on a predictive coding view, we consider the nature of these sound representations and how they compete with each other. Predictive processing helps to maintain perceptual stability by signalling the continuation of previously established patterns as well as the emergence of new sound sources. It also provides a measure of how well each of the competing representations describes the current acoustic scene. This account of auditory stream segregation has been tested on perceptual data obtained in the auditory streaming paradigm.

“…Roberts et al [21] studied the build-up and resetting of streaming using an objective rhythm-discrimination task, for which performance was expected to be relatively poor when obligatory segregation occurred. A 2.0 s fixed-frequency inducer sequence was followed by a 0.6 s test sequence of alternating pure tones (3 low (L)-high (H) cycles).…”

A sequence of sounds may be heard as coming from a single source (called fusion or coherence) or from two or more sources (called fission or stream segregation). Each perceived source is called a ‘stream’. When the differences between successive sounds are very large, fission nearly always occurs, whereas when the differences are very small, fusion nearly always occurs. When the differences are intermediate in size, the percept often ‘flips’ between one stream and multiple streams, a property called ‘bistability’. The flips do not generally occur regularly in time. The tendency to hear two streams builds up over time, but can be partially or completely reset by a sudden change in the properties of the sequence or by switches in attention. Stream formation depends partly on the extent to which successive sounds excite different ‘channels’ in the peripheral auditory system. However, other factors can play a strong role; multiple streams may be heard when successive sounds are presented to the same ear and have essentially identical excitation patterns in the cochlea. Differences between successive sounds in temporal envelope, fundamental frequency, phase spectrum and lateralization can all induce a percept of multiple streams. Regularities in the temporal pattern of elements within a stream can help in stabilizing that stream.
