Attention effects on auditory scene analysis in children.
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...
متن کاملComparing auditory sustained attention in children with auditory processing disorder and normal children
Introduction: Auditory processing disorder (APD) is a type of abnormal perceptual processing of auditory information within the central auditory nervous system that could be influenced by cognitive factors, such as attention. Attention is one of most important cognitive functions in the development of learning in children, so it is important to recognize and evaluate a variety of attention defi...
متن کاملTemporal coherence and attention in auditory scene analysis.
Humans and other animals can attend to one of multiple sounds and follow it selectively over time. The neural underpinnings of this perceptual feat remain mysterious. Some studies have concluded that sounds are heard as separate streams when they activate well-separated populations of central auditory neurons, and that this process is largely pre-attentive. Here, we argue instead that stream fo...
متن کاملEffects of location, frequency region, and time course of selective attention on auditory scene analysis.
Often, the sound arriving at the ears is a mixture from many different sources, but only 1 is of interest. To assist with selection, the auditory system structures the incoming input into streams, each of which ideally corresponds to a single source. Some authors have argued that this process of streaming is automatic and invariant, but recent evidence suggests it is affected by attention. In E...
متن کاملEffects of self-motion on auditory scene analysis.
Auditory scene analysis requires the listener to parse the incoming flow of acoustic information into perceptual "streams," such as sentences from a single talker in the midst of background noise. Behavioral and neural data show that the formation of streams is not instantaneous; rather, streaming builds up over time and can be reset by sudden changes in the acoustics of the scene. Here, we inv...
