“…Critically, this and other previous studies using tone omissions [e.g., Yabe et al (1997Yabe et al ( , 1998Yabe et al ( , 2001, Shinozaki et al (2003), and Winkler et al (2005)] did not manipulate the sequential predictability of the omitted tone. The present study reveals that initial processing similarities are only observed with full predictability of the omitted tone, but not with partial predictability as given in the restorable and control conditions.…”

The auditory system has been shown to detect predictability in a tone sequence, but does it use the extracted regularities for actually predicting the continuation of the sequence? The present study sought to find evidence for the generation of such predictions. Predictability was manipulated in an isochronous series of tones in which every other tone was a repetition of its predecessor. The existence of predictions was probed by occasionally omitting either the first (unpredictable) or the second (predictable) tone of a same-frequency tone pair. Event-related electrical brain activity elicited by the omission of an unpredictable tone differed from the response to the actual tone right from the tone onset. In contrast, early electrical brain activity elicited by the omission of a predictable tone was quite similar to the response to the actual tone. This suggests that the auditory system preactivates the neural circuits for expected input, using sequential predictions to specifically prepare for future acoustic events.

“…We cannot determine whether attention modified the stream segregation process or the MMN process (or both). Previous studies have indicated that the two processes (auditory stream segregation and MMN change detection process) are distinct, by showing that the stream segregation process precedes the MMN deviance detection process in time (Sussman, 2005;Sussman et al, 1998Sussman et al, , 1999Sussman et al, 2001;Yabe et al, 2001). This suggests that the two processes might have operated independently of one another and attention could have modified one and not the other.…”

In natural situations, the auditory system is confronted with overlapping acoustic input from several simultaneously active sources at any given time. An important aspect of auditory processing is to sort the overlapping inputs into groups, each from a single source, a process called auditory scene analysis (ASA;Bregman, 1990). The ASA process facilitates our ability to choose one stream of information within a background of sounds emanating from many different sources, such as when listening to a stream of speech in a crowded room. The cocktail party provides an example of a situation in which it is common to attend to one stream of speech (one conversation in the room: the foreground ) while ignoring the rest of the auditory information (the other conversations and noise in the room: the background ).The present study focuses on a central scientific question in ASA theory: Which of the following views is more accurate?1. Streams are structured without focused attention, by preattentive processes operating over the whole set of sounds that are present. If this is true, more than one stream can be formed at the same time, despite the fact that attention may choose one or another for further processing.2. Attention is required to form a stream. Under this hypothesis, only a single stream is ever present as a structured perceptual entity-the one created by attention out of a subset of the sounds that are present. The unattended tones are simply an unstructured background. As attention shifts, different streams are formed, enduring only as long as attention remains focused on the stream.To address the question, we tested the extent to which unattended sounds are processed when one auditory stream is selected from a set of potential ones. Specifically, by using tones spanning three frequency ranges, we were In three experiments, we addressed the issue of attention effects on unattended sound processing when one auditory stream is selected from three potential streams, creating a simple model of the cocktail party situation. We recorded event-related brain potentials (ERPs) to determine the way in which unattended, task-irrelevant sounds were stored in auditory memory (i.e., as one integrated stream or as two distinct streams). Subjects were instructed to ignore all the sounds and attend to a visual task or to selectively attend to a subset of the sounds and perform a task with the sounds (Experiments 1 and 2). A third (behavioral) experiment was conducted to test whether global pattern violations (used in Experiments 1 and 2) were perceptible when the sounds were segregated. We found that the mismatch negativity ERP component, an index of auditory change detection, was evoked by infrequent pattern violations occurring in the unattended sounds when all the sounds were ignored, but not when attention was focused on a subset of the sounds. The results demonstrate that multiple unattended sound streams can segregate by frequency range but that selectively attending to a subset of the sounds can modify the extent to whic...

“…For instance, it has been suggested that streaming occurs preattentively, because the mismatch negativity (MMN), which can occur in the absence of attention, is elicited only within streams (Sussman et al, 1999;Yabe et al, 2001). In contrast, it has been shown that the MMN can be modulated by attention in experiments comprising complex attentional loads (Alain and Izenberg, 2003).…”

The brain is constantly faced with the challenge of organizing acoustic input from multiple sound sources into meaningful auditory objects or perceptual streams. The present study examines the neural bases of auditory stream formation using neuromagnetic and behavioral measures. The stimuli were sequences of alternating pure tones, which can be perceived as either one or two streams. In the first experiment, physical stimulus parameters were varied between values that promoted the perceptual grouping of the tone sequence into one coherent stream and values that promoted its segregation into two streams. In the second experiment, an ambiguous tone sequence produced a bistable percept that switched spontaneously between one-and two-stream percepts. The first experiment demonstrated a strong correlation between listeners' perception and long-latency (Ͼ60 ms) activity that likely arises in nonprimary auditory cortex. The second demonstrated a covariation between this activity and listeners' perception in the absence of physical stimulus changes. Overall, the results indicate a tight coupling between auditory cortical activity and streaming perception, suggesting that an explicit representation of auditory streams may be maintained within nonprimary auditory areas.
