Human cortical activity during streaming without spectral cues suggests a general neural substrate for auditory stream segregation.
The brain continuously disentangles competing sounds, such as two people speaking, and assigns them to distinct streams. Neural mechanisms have been proposed for streaming based on gross spectral differences between sounds, but not for streaming based on other nonspectral features. Here, human listeners were presented with sequences of harmonic complex tones that had identical spectral envelope...
متن کاملHuman auditory cortex activity shows additive effects of spectral and spatial cues during speech segregation.
In noisy social gatherings, listeners perceptually integrate sounds originating from one person's voice (e.g., fundamental frequency (f(0)) and harmonics) at a particular location and segregate these from concurrent sounds of other talkers. Though increasing the spectral or the spatial distance between talkers promotes speech segregation, synergetic effects of spatial and spectral distances are...
متن کاملActivity associated with stream segregation in human auditory cortex is similar for spatial and pitch cues.
Streaming is a perceptual mechanism by which the brain segregates information from multiple sound sources in our environment and assigns them to distinct auditory streams. Examples for streaming cues are differences in frequency spectrum, pitch, or space, and potential neural correlates for streaming based on spectral and pitch cues have been identified in the auditory cortex. Here, magnetoence...
متن کاملRelation between Working Memory Capacity and Auditory Stream Segregation in Children with Auditory Processing Disorder
Background: This study assessed the relationship between working memory capacity and auditory stream segregation by using the concurrent minimum audible angle in children with a diagnosed auditory processing disorder (APD).Methods: The participants in this cross-sectional, comparative study were 20 typically developing children and 15 children with a diagnosed APD (age, 9–11 years) according to...
متن کاملThe Effect of Working Memory Training on Auditory Stream Segregation in Auditory Processing Disorders Children
Objectives: This study investigated the efficacy of working memory training for improving working memory capacity and related auditory stream segregation in auditory processing disorders children. Methods: Fifteen subjects (9-11 years), clinically diagnosed with auditory processing disorder participated in this non-randomized case-controlled trial. Working memory abilities and auditory strea...
