“…This interpretation in terms of perceptual masking is consistent with psychoacoustic data showing maturation of both auditory stream segregation (Sussman et al, 2007) and perceptual masking for non-speech stimuli (Hall et al, 2005). However, other data indicate that children are poorer than adults at recognizing speech based on spectrally and/or temporally sparse cues, even in cases where perceptual isolation of target cues is not thought to play a role in performance Elliott et al, 1987;Mlot et al, 2010).…”

Children perform more poorly than adults on a wide range of masked speech perception paradigms, but this effect is particularly pronounced when the masker itself is also composed of speech. The present study evaluated two factors that might contribute to this effect: the ability to perceptually isolate the target from masker speech, and the ability to recognize target speech based on sparse cues (glimpsing). Speech reception thresholds (SRTs) were estimated for closed-set, disyllabic word recognition in children (5-16 years) and adults in a one-or two-talker masker. Speech maskers were 60 dB sound pressure level (SPL), and they were either presented alone or in combination with a 50-dB-SPL speech-shaped noise masker. There was an age effect overall, but performance was adult-like at a younger age for the one-talker than the two-talker masker. Noise tended to elevate SRTs, particularly for older children and adults, and when summed with the one-talker masker. Removing timefrequency epochs associated with a poor target-to-masker ratio markedly improved SRTs, with larger effects for younger listeners; the age effect was not eliminated, however. Results were interpreted as indicating that development of speech-in-speech recognition is likely impacted by development of both perceptual masking and the ability recognize speech based on sparse cues.

“…Frequency separation between the highest, lowtone and the lowest, high-tone was four semitones. At a four semitone frequency separation between tone ranges, listeners perceive one integrated stream of sounds 50% of the time and two segregated streams 50% of the time (Bregman, 1999;Sussman et al, 2007). In other words, the sound stream organization was ambiguous.…”

Visual cues can modulate integration and segregation of objects in auditory scene analysis

et al. 2007

The task of assigning concurrent sounds to different auditory objects is known to depend on temporal and spectral cues. When tones of high and low frequencies are presented in alternation, they can be perceived as a single, integrated melody, or as two parallel, segregated melodic lines, according to the presentation rate and frequency distance between the sounds. At an intermediate distance, in the 'ambiguous' range, both percepts are possible. We conducted an electrophysiological experiment to determine whether an ambiguous sound organization could be modulated toward an integrated or segregated percept by the synchronous presentation of visual cues. Two sets of sounds (one high frequency and one low frequency) were interleaved. To promote integration or segregation, visual stimuli were synchronized to either the within-set frequency pattern or to the across-set intensity pattern. Elicitation of the mismatch negativity (MMN) component of event-related brain potentials was used to index the segregated organization, when no task was performed with the sounds. MMN was elicited only when the visual pattern promoted the segregation of the sounds. The results demonstrate cross-modal effects on auditory object perception in that sound ambiguity was resolved by synchronous presentation of visual stimuli, which promoted either an integrated or segregated perception of the sounds.

“…The sound sequence was perceptually ambiguous for hearing one or two sound streams, as determined in a separate behavioral study that used the same type of stimulus paradigm as in the current study (Sussman et al, 2005b). In the behavioral study, listener's heard two distinct streams approximately 50% of the time at a 5-semitone frequency separation.…”

Neurophysiological evidence for context-dependent encoding of sensory input in human auditory cortex

Attention biases the way in which sound information is stored in auditory memory. Little is known, however, about the contribution of stimulus-driven processes in forming and storing coherent sound events. An electrophysiological index of cortical auditory change detection (mismatch negativity [MMN]) was used to assess whether sensory memory representations could be biased toward one organization over another (one or two auditory streams) without attentional control. Results revealed that sound representations held in sensory memory biased the organization of subsequent auditory input. The results demonstrate that context-dependent sound representations modulate stimulusdependent neural encoding at early stages of auditory cortical processing.
