Estimating working memory based on a divided-attention version of the spatial release from masking task

Spatial release from masking for an individual is dependent on the spatial separation between the target and the maskers, age, auditory capabilities, and working memory capacity. In this paper, a task is presented that estimates an individual's working memory capacity using a divided-attention version of the classic spatial release from masking task. Speech identification thresholds, temporal overlap thresholds, and working memory were measured for younger and older adults. The results showed younger listeners had better thresholds than older listeners across all the tests. Overall, this test can simultaneously estimate an individual's working memory and spatial processing capabilities.
