| summary | Auditory stimuli are represented in multiple ways at different levels within the auditory system. The different representations or “maps” may reflect different stimulus features, such as bandwidth or modulation frequency, although audio frequency is usually one dimension of the maps (the tonotopic dimension). When a human listener is asked to detect or discriminate stimuli based on a specific auditory feature, performance may be best when attention is focused on the map which best represents that feature. In this talk, I will describe the results of a range of detection tasks in which cues are used to focus attention on the most appropriate stimulus representation. The cues may directly reflect the crucial stimulus features, or may represent those features in a more abstract way. Under some conditions, the cues are ineffective, and this provides insights into the limits of auditory processing. |
