The sequential organization of sound over time can interact with the concurrent organization of sounds across frequency. Previous studies using simple acoustic stimuli have suggested that sequential streaming cues can retroactively affect the perceptual organization of sounds that have already occurred. It is unknown whether such effects generalize to the perception of speech sounds. Listeners'...
The present study investigates the effect on auditory stream segregation of the duration of silent gaps between items of a repeating sequence of sine tone stimuli. While previous investigators had •hown that gaps reduced the tendency for items to segregate, the present experiment showed that this was not the case; rather, in adjusting tone durations for stream segregation thresholds, subjects i...
Individuals with Asperger syndrome (AS) often have difficulties in perceiving speech in noisy environments. The present study investigated whether this might be explained by deficient auditory stream segregation ability, that is, by a more basic difficulty in separating simultaneous sound sources from each other. To this end, auditory event-related brain potentials were recorded from a group of...
While cochlear implants (CIs) usually provide high levels of speech recognition in quiet, speech recognition in noise remains challenging. To overcome these difficulties, it is important to understand how implanted listeners separate a target signal from interferers. Stream segregation has been studied extensively in both normal and electric hearing, as a function of place of stimulation. Howev...
Auditory stream segregation is know as a process whereby sound elements are separated and integrated into some perceptual objects as a coherent whole, in the auditory scene analysis. Such a perceptual faculty is considered to be dependent on some factors in sounds such as similarity, good continuation, common fate, disjoint allocation, closure, and so on. For example, when we listen to fast alt...
Researchers of auditory stream segregation have largely taken a bottom-up view on the link between physical stimulus parameters and the perceptual organization of sequences of ABAB sounds. However, in the majority of studies, researchers have relied on the reported decisions of the subjects regarding which of the predefined percepts (e.g., one stream or two streams) predominated when subjects l...
