This study finds that attention enhances spatial release from informational masking using event-related potentials.
Spatial separation of multiple talkers reduces listener confusion (i.e. informational masking), improving speech processing. This spatial release from informational masking is thought to reflect automatic processes of stream segregation and improvements in selective attention. However, the relative contributions of bottom-up and top-down processing and their potential interactions remain unclear. This study investigated the role of attention in the spatial release from informational masking using event-related potentials.
