Auditory scene analysis begins in infancy, making it possible for the baby to distinguish its mother's voice from other noises in the environment. Despite the importance of this process for human behavior, the question of how perceptual sound organization develops during childhood is not well understood. The current study investigated the role of attention for perceiving sound streams in a grou...

When human subjects hear a sequence of two alternating pure tones, they often perceive it in one of two ways: as one integrated sequence (a single "stream" consisting of the two tones), or as two segregated sequences, one sequence of low tones perceived separately from another sequence of high tones (two "streams"). Perception of this stimulus is thus bistable. Moreover, subjects report on-goin...

Three experiments explored the effects of abrupt changes in stimulus properties on streaming dynamics. Listeners monitored 20-s-long low- and high-frequency (LHL–) tone sequences reported number streams heard throughout. Experiments 1 2 used pure tones examined changing triplet base frequency level, respectively. Abrupt (±3–12 semitones) caused significant magnitude-related falls segregation (r...

Segregation has been widely discussed by social scientists and especially by urban geographers and planners over the past decades. However, regardless of their focus, most of these studies view segregation as an obvious case of spatial injustice. I argue that this implicit relationship between segregation, (in) justice, and space needs to be reexamined. This paper approaches this task by review...
